| No. Patentee. Title 525,864 C.T.Doscasile Apparatus for testing friction of bearings or efficiency of lubricating. A test lever is mounted on a rotatable shaft to measure the frictional torque exerted by the shaft on the lever and the friction or bearing pressure between the lever and shaft is applied by a force-exerting unit e.g. a spring, pendulum or weight bodily and completely carried by the lever. 525,877 J.J.V.Armstrong Fuel-injection (Bosch Ges) apparatus for internal combustion engines. Injection apparatus in which timing is varied hydraulically in dependance upon the rate of delivery of fuel by a pumping means alone. The invention concerns the hydraulic adjusting means which comprises a spring controlled piston dividing a cylinder into two chambers connected by a passage of varying cross-section area. 525,880 Fairey Aviation Co.Ltd., Signalling, indicating or like means for J.L.Hills and P.B. Howell use in fog. The invention is for means for making infra red light visible to the human eye for fog signalling 525,910 J.H.Pratt, G.E. Manley and Braking mechanism. A.H.G.Girling. The braking mechanism comprises a hydraulic cylinder carried by and fixed relatively to the said lever, a piston rod reciprocally mounted within the hydraulic cylinder and having at its outer end an operating head in which the braking effort is exerted and a flexible connection between the hydraulic cylinder and the operating mechanism for those of the brakes which are operated hydraulically and a mechanical connection between the lever and the brakes which are operated mechanically so that one execution of a braking effort this effort is transferred hydraulically to the hydraulic brakes and mechanically to the mechanical brakes by reason of the lever being | ||
