SEPTEMBER 25, 1919 SIDE-WINDS RECENTLY a new Order in Council was issued by the Home Office touching upon the regulations which govern the manu facture and supply of acetylene compressed in cylinders, known as dissolved acetylene. The Dissolved Acetylene Co., Ltd., formerly the Acetylene Equipment Co., Ltd., sole manufacturers of D.A. (dissolved acetylene) and who, we understand, are the largest suppliers of this gas in Great Britain have made careful tests and experiments in regard to the question of acetylene cylinders and gas, with the object of maintaining their standard of quality and adhering in all respects to the Home OfEce regulations. SOME time ago, acting upon Home Office recommendations, they commenced the reconstruction and re-testing of all cylinders with the object of improving their durability. They have now introduced an entirely new form of cylinder made from a steel shell solid drawn from one piece. This type of cylinder has previously been obtainable only in heavy sections, which would have made the cost of transport pro hibitive. Final experiments, however, have now led to the production of this type of cylinder in a section light enough for transport, but at the same time heavy enough to with stand the hydraulic test pressure of 1,000 lb. per sq. in., which exceeds that specified by the Home Office regulations, i.e., four times the working pressure, the latter being in creased under the new Order from 150 lb. to 225 lb. per sq. in. These cylinders after testing, are filled with the necessary porous material and acetone, then fitted with valves and filled with acetylene ready for use. These pro cesses are carried out at the company's works, the cylinder being thus manufactured entirely in Great Britain by British labour. The Dissolved Acetylene Co. supply their gas under a guarantee of purity, and it may be mentioned that the gas, after generation, is treated by six processes of puri fication, so as to extract all moisture and impurities. " SUMMER-TIME " ends during the night of'September 29- 30 and at 2 a.m. we resume normal time again. It will be necessary for clocks to be put back one hour, and for the information of the many users of " Pulsynetic " clocks we are informed by the makers that the best method of altering electric clocks of the " Pulsynetic " class is to stop the pendulum of the transmitting clock for one hour, and this recommendation also applies to ordinary domestic striking clocks, as in these it is fatal to put the hands backwards. " Pulsynetic " clock systems which include in their circuits public or turret clocks, should be altered after dusk on Sunday night; but works and factory systems—of which there is now a large number—can be more conveniently stopped on Saturday after closing time, provided, of course, that a public clock is not connected with the system. An excellent suggestion in connection with watches—given by an expert watchmaker—is to put the watch quickly- back to, say, seven or eight minutes beyond the necessary- hour, then slowly turn the hands forwards to the correct time. When the watch is put back slowly to the correct time there is the danger of stopping the watch, and if not noticed the results may be, to say the least, inconvenient. IN order to cope with their greatly increased business— both export and in London and the Home counties—Messrs. Dunford and Elliott (Sheffield), Ltd., the well-known firm of steel manufacturers, have found it necessary to open their own offices in London, at 4, Copthall Buildings, Copthall Avenue, E.C. 2, and in future all communications in con nection with steel, etc., for export or for delivery in London and the south of England, should be sent to the new address. The general management of the London office is in the hands of Mr. Ivor S. Winby, who has hitherto controlled Messrs. Dunford and Elliott's export business, whilst the services of their London agent, Mr. E. St. Clair Duncan, are retained in the capacity of sales manager. IN these days, when so much is heard of the lauded enter prise of almost every other country but our own, it is refresh ing to record an instance of British brains, British capital and British inventiveness, making headway against all comers. Little more than two years ago Messrs. Madgwick, Ltd., patentees and proprietors of the well-known " M-Ten " crates and boxes, took in hand the problem of packing. They designed a collapsible crate or box so constructed that while it requires neither nails or screws, hinges or wires, it is capable when put together of holding any kind of mer chandise, from the heaviest to the lightest. An ingenious system of interlocking the parts makes it perfectly rigid, therefore it can be used for packing goods in precisely the same manner as the ordinary nailed-up crate or box, and can be used time after time. When empty the case can be collapsed, and top, sides, bottom and ends fold up as flat as a book. Thus saving 80 per cent, storage room. THAT this invention had a great future before it there was no doubt, but it is entirely due to the energy of the patentees and proprietors that, in the short space of time mentioned above, they have outgrown their original works at East Row, N. Kensington, and are removing to a splendid site in Sudbury, Middlesex. There they have erected large works to cope with the ever-increasing flood of orders. That these crates and boxes are appreciated alike by users and railway com panies is evidenced by the fact that, first, they are being used by the leading firms in nearly every line of business, and, second, the railway companies will accept goods packed in these crates and boxes at company's risk. Messrs. Madgwick will be in their new premises in October, and will be glad to demonstrate their speciality to any manufacturer who desires to find an easy way out of the packing problem. The new premises will be know as " M-Ten " Works. A METHOD of " sealing " these cases has been adopted and has met with the unqualified approval of the Railway com panies. Any ordinary rigid and nailed-up case—whether banded, wired or other means are used—is "easy" to the average railway thief armed with jemmy and nail-drawer, and not the slightest sign of pilferage is left behind. The " M-Ten " case, however, when sealed in the approved manner, is claimed to be positively pilfer-proof and will defy the efforts of the experts—goods cannot be extracted or tampered with without leaving behind the obvious signs that will '* stop " the case in transit and on which the railway companies will make good losses, without demur. MR. CLARENCE WINCHESTER'S resignation from the Grahame- White Co., Ltd., Hendon, takes effect at the end of this month. CAPT. TRUELOVE and his red and yellow Avro have arrived safely in xSpain. Gen. Echague, commanding the Spanish Flying Corps, has been taken up by Capt. Truelove, and much enjoyed his flight. He displayed great interest in the type of machine on which the British fighting pilots were trained. It is understood that His Majesty King Alphonso is acquiring'this Avro. " LA SociETfe FRANCHISE BARIMAR " is the title of a com pany which has recently been formed in Paris, with a capital of ^5,000, to exploit the Barimar scientific welding processes in France, Tunis and Algeria. The factory, which is situate at 48, Rue d'Alsace, Clichy (Seine), is under the personal supervision of Mr. Cyril Rose, an assiduous engineer, deeply interested in metalliferous subjects. Mr. Rose, who has taken a leading part in the establishment of the new com pany, is constantly investigating the problems of metal fusion, with the one object of obtaining the very best results from modern scientific welding processes, and, under his able management, the French branch should speedily thrive. THE Lep Transport and Depository, Ltd., whose confidence in commercial aviation was manifested by the opening of their magnificent Aerial Travel Office in Piccadilly Circus on May 1—the opening day of civil aviation—have now opened a temporary office as aircraft brokers at Hounslow. The functions of the department are similar to those of a shipbroker, i.e., clearing machines and their cargoes through Customs, both on outward and inward journeys, for which a scale of inclusive charges has been prepared. Mr. R. A. Loader, who is in charge of the department, will give all available assistance to aerial transport firms and their pilots, both in Customs formalities and in regard to the booking of passengers and facilities for collection, delivery and handling of freight. A BOOKLET which will be found of considerable use by those who use Exide Starting and Lighting batteries has just been issued by the Chloride Electrical Storage Co., Ltd. The booklet deals with the charging and operating of both Exide and Clifton batteries in ebonite boxes ; it is written in very simple language, and a diagram showing the connections of the charging circuit, when using lamps as resistances, is given. A copy is sent out with each battery, but the Chloride Co. will be pleased to send a copy to anyone who would be able to make use of it if they address their application to the head office at Clifton Junction, Manchester. 1299
