FLIGHT, 1 July 1955 THE INDUSTRY Kelvin Hughes Directorships SEVEN appointments have been made to Boards of three of thesubsidiary companies of Kelvin and Hughes, Ltd. Details are as follows: To the Board of Kelvin and Hughes (Aviation), Ltd.:Mr. F. W. Bates, recently appointed to the Board of the parent company; Mr. R. W. Dunn, A.F.R.Ae.S., chief engineer (aviationinstruments); Mr. D. H. Perkins, works manager, Kelvin Hughes Works, Basingstoke; and Mr. G. Wikkenhauser, chief develop-ment engineer, Barkingside factory. To the Board of Kelvin and Hughes (Industrial), Ltd.: Mr. P. J. A. Turner, chief engineerat the Glasgow factory. To the Board of Kelvin Hughes (Marine), Ltd.: Mr. H. R. Whitfield, chief radar engineer; Mr. R. M.Stephenson, overseas sales manager. Broadly, the relationship of the companies within the group isthat Kelvin and Hughes are responsible for research, development and the manufacture of all equipment produced by each of thefactories at Barkingside (London), Basingstoke (Hants) and Hill- ington (Glasgow). The subsidiary companies, covering aviation,industrial and marine products, are responsible for the sales and servicing of this equipment. Delay Relay FROM Electro Methods, Ltd., of Caxton Way, Stevenage,Herts, come details of a new D.C. pneumatic time-delay relay. It is intended for such 240v duties as controlling motor-contactors, timing the opening and closing of valves in various types of apparatus, and controlling sequential-process operationsin which accuracy and reliability are essential. Consisting basically of a solenoid and a spring-loaded bellowsof synthetic rubber provided with an adjustable air-valve, the relay operates in the following manner: When the solenoid isde-energized, its plunger is withdrawn from the coil by the spring loading and the bellows are compressed. On the solenoid-being energized, the plunger is retracted into the coil, thereby f permitting the bellows to expand under their own spring tension.[Expansion time is pre-determined by the setting of the air-valve. I At the end of the expansion cycle a snap-action double-break-tand-make switch is automatically engaged and held until the [solenoid is de-energized, whereupon the switch-contacts snap* over, and the plunger is withdrawn from the coil to re-compress ? the bellows. Family Business Centenary THE firm of Herbert Terry and Sons, Ltd., well known asmakers of springs and spring components, are celebrating their 100th anniversary.The firm was founded by Mr. Herbert Terry, who, starting in a small way with wire parts for the fishing-tackle trade, waspresently able to supply the needs of the expanding engineering, cycle and motor industries. In 1902, Mr. Terry relinquished control of the firm, and histhree sons, Charles, Victor and Alfred, took control. The first- named was chairman for 41 years and concerned himself withthe financial side; the second was the inventor; and the third was mainly interested in the sales side. Today the firm is under the control of Mr. Norman V. Terry^ (chairman), son of Victor Terry; Mr. H. Philip Terry, son of [Charles; and Mr. David E. Terry, son of the late C. Douglas[Terry, and grandson of Alfred Terry. I To celebrate the centenary, the workers are being awarded, in•addition to their profit-sharing bonus, £1 for each year's service (with the firm; this will mean a share-out of about £25,000.

The American company specialize in the manufacture of aircraft freight-lashing equipment; they also produce automaticbelts for ejection-seats, and have introduced a new helicopter sling release hook. Rollason Aerocessories—who have recently receiveda M.o.S. order for quick-release lashings for airborne-cargo drop- ping—will be undertaking such work in addition to their usualproduction of testing and servicing equipment and sensitive con- trol valves and regulators. Design Councillor T^EWLY elected a member of-1-' the Hawker Siddeley Group design council is Mr. Charles A.Grinyer, vice-president and chief engineer of Orenda Engines, Ltd.The council provides for an in- terchange of ideas and experi-ence among the technical heads and chief designers of Groupcompanies, and meets twice a year. Mr. Grinyer joined OrendaEngines, a member of the A. V. Roe Canada group, in 1952 fromthe Bristol Aeroplane Company. His early training included workin combustion problems and centrifugal and axial-flow compressors when they were virtuallyunknown in the aero-engine industry. During the early years of World War II, while Technical Assistant to the Deputy Director of Engine Inspection at the Ministry of Supply, he co-ordinatedall gas turbine test procedures in Great Britain. Non-destructive Testing A SPECIALIST in methods of non-destructive testing, Mr.William C. Hitt, assistant chief of quality control at the Douglas Santa Monica plant, recently visited London. Whilethere he gave an informal lecture—organized by Inspection Equipment, of 19 Broad Court, Drury Lane, London, W.C.2, andillustrated by an Eastman colour film—on the inspection tech- niques used at Santa Monica. Among the methods shown was the use of fluorescent penetrantsfor the examination of wing spar caps; the vibration-and-sand method of detecting lack of bond in such assemblies as honeycombsandwiches; ultrasonic examination of bars and forgings; and Magnaflux examination of the depth of scratches on skin panels.The main theme of Mr. Hitt's talk, however, was to describe applications of X-ray photography for the examination of certainprimary and secondary structures without the need for dismantling. He showed a number of X-ray slides which demonstrated thevalue of this method. IN BRIEF Mr. John W. R. Taylor, who has been engaged on the publicityside of the Fairey business for the past eight years, has left in order to devote all his activities to free-lance journalism—inwhich connection he is particularly well known as a writer on aircraft recognition and historical subjects, and as a reviewer. Thecompany has "accepted his resignation with regret." * * * Mr. C. G. F.
