232 FLIGHT. MARCH 2, 1939 THE INDUSTRY (CONTINUED) New Companies in 1938 ACCOKDING to statistics compiled by Jordan and Sons, the company registration agents, 81 new companies concerned with aviation were registered during 1938 ; only one of these was a public company. The total capital involved was £736.299. Among the biggest capital figures recorded was the £100,000 of Simmonds Aerocessories (Western), Ltd., and the £125,000 of Crouch-Bolas (Aircraft Appliances), Ltd. A Water Degreasing Process REFERENCE to the sale by Brown Brothers, Ltd., of a degreasing preparation known as Gunk was made recently in these pages. The material is distributed in this country by Charles Mack and Co., 84-85, Trevelyan Buildings, Corpora tion Street, Manchester, 4. Some further tests have been carried out which indicate that Gunk has, in fact, some very valuable properties. It is a dark, heavy liquid with a strong "disinfectant" smell, but it will not damage fabric, paint, leather or wood; it is non- injurious to the hands and there are no toxic fumes. Its action is to saponify mineral oils so that a water-soluble emulsion is formed. Animal oils and fats can also be treated, but it does not react with vegetable oils. Since it is harmless to fabrics and paint, surfaces which have been covered by oil spray can—if lightly smeared or sprayed with Gunk—be washed down with water and, without rubbing, all oil is removed. Thus it has obvious possibilities for cleaning wings and fuselage and other parts liable to be spattered by oil spray. Fabrics, such as ckaning cloths, overalls, etc., no marl- how loaded with oil, if dipped bodily into the preparation ca be rinsed out in cold water, after the surplus Gunk has bee wrung out back into the container, and emerge quite as clea as if they had been boiled in soap suds, and suffer neither shrinkage nor weakening. Apart from mechanical parts, which may be either sprayed, brushed or dipped, before water washing, Gunk will enable oil to be hosed with cold water from concrete floors and even long-standing oil stains in concrete or wooden floors can be eliminated by two or three applications. Gunk will emulsify three or four times its own bulk of mineral oil, so that it is quite economical to use. Many appli cations, apart from the foregoing, have been tested independ ently of its sponsors, and it may be stated that oil can be removed completely from any material or mechanism that can be safely given the final wash with cold water. "Wetflex" Pistons EXHIBITED at the Birmingham section of the British In dustries Fair., and commented upon in these pages last week, the " Welfiex " products of Wellworthy, Ltd., are pistons, and not piston rings. Fastening the 95's Cowlings 'pHE name of Thos. P. Headland, Ltd., of 164-168, West- -*- minster Bridge Road, London, S.E.i, should be added to the recently published list of suppliers of equipment for the D.H. 95 ; their " DZUS " self-locking fasteners are used on the cowlings and elsewhere.
