Title: Steering mechanism for road vehicles
IPC: B62D7/16
Filed: 1945-07-18
Abstract: 603,244. Motor-vehicle steering-gear. SOC. GRAM ELECTRIC. July 18, 1945, No. 18381. Convention date, Oct. 18, 1944. [Class 79 (v)] A steering device for the front wheels of a motor vehicle comprises a transverse shaft in front of the axle and rotatable by a steering wheel, a drag link secured to each end of said shaft and coupled to a steering arm on the respective road wheel hub, so as to leave a clear space between the front wheels extending forwardly to the transverse shaft. Fig. 1 shows a transverse shaft 1 rotatable by a steering wheel 2 and column by means of a worm and sector. The ends of the shaft are provided with levers 3, 4 respectively coupled bv rods 5, 6 to the steering arms 7, 8 on the wheel hubs 9, 10. Coupling is effected by ball and socket joints. The levers 3 and 4 are angularly displaced from the vertical and towards each other by an angle α, the effect of which allows the correct angular displacement of the wheels when cornering so that the turning circles of the wheels have a common centre. Alternatively the arms 7, 8 may be swept back to achieve this result, or the angular displacements of both arms and levers may be combined.

Abstract: 692,757. Frequency measuring. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 9, 1951 [Aug. 11, 1950], No. 18780/51. Drawings to Specification. Class 37. [Also in Group XL (c)] In a tuning system for the klystron local oscillator of a radar transmitter-receiver a sweep voltage varies the frequency of the oscillator, and the indication of the mean frequency is obtained by applying the sweep voltage and the output from the intermediate frequency amplifier to the deflecting electrodes of a cathode-ray tube. A sinusoidal 60 c/s. sweep voltage is used to sweep the frequency of the oscillator and also to operate as the time base of the normal display tube. The resulting output from the I.F. amplifier due to an incoming signal is used to displace the spot vertically so that in effect the tube displays the frequency response characteristic of the receiver, the position of the peak of the response curve indicating the relative frequency of the signal and the local oscillator. The tuning of the oscillator is then adjusted until the peak occurs at the centre of the sweep, i.e. when the instantaneous sweep voltage is zero. The incoming signal may be the reflected signal or may be derived from the adjacent transmitter either directly or by use of an " echo box." Specification 639,133, [Group XL (c)], is referred to.
