| No. Patentee. Title. 525,636 V.Seklehner Direction indicators for automobiles. To warn driver that he hasn't returned his direction indication a second circuit in parallel with indicator circuit is provided with a resistance which heats a bi-metallic strip which in turn closes a circuit including a warning light or noise. 525,658 Automotive Products Friction coupling Co.Ltd and G.R.C.Yates devices for servo-brake mechanism. A brake servo of the frictional type employs a multi plate clutch. The abutment member towards which discs are urged when clutch is engaged carries an intermediate member between itself and the discs coupled to the abutment but capable of slight tilting movement relative thereto in angular so that angular relation of discs to axis of device is independent of angular relation between abutment member and said axis. 525,664 R.Bosch Ges. Fuel injection apparatus for internal combustion engines. Invention applies to known apparatus in which the overflow through a constant relief valve between a feed pump and an injection pump operates apparatus which adjusts the timing. The invention is concerned with the means by which this overflow operates the timing control so as to vary the same in dependance on the amount of fuel supplied to the injection pump and the amount consumed thereby. 525,665 R.Bosch Ges. Fuel injection apparatus for internal combustion engines. Specification says that fuel injection apparatus is known in which the timing is responsive to difference between rate of delivery by a pump and rate of consumption of injection pump. P.T.O. | ||
