Title: An improved vehicle suspension
IPC: B60G7/02
Filed: 1959-04-10
Abstract: 854,423. Spring suspensions. FORD MOTOR CO. Ltd. (Ford Motor Co.). April 10, 1959, No. 12237/59. Class 108(2). In a vehicle suspension system the driving wheels are suspended in such a manner that an assumed point on one of the wheels moves in different paths during vehicle acceleration and deceleration. A wheel 17, Fig. 2 is suspended from a chassis by levers 12, 19. The lever 19 is connected to a bracket 26 on the chassis by a shackle 23 resiliently held in a mid-position by springs 33, 34. When the vehicle accelerates, the lever 19 exerts a rearward force on the shackle 23, compressing the spring 34. A point 29 on the wheel now moves along a path PA. This path is at an angle with the vertical line through the wheel centre. When the vehicle brakes, a forward force is exerted by the lever 19 which compresses the coil spring 33. The point 29 now moves along a path PB. This path is also at an angle to the vertical line. through the wheel centre, but subtends a greater angle with ,the vertical than the path PA. Instead of coil springs 33, 34 a pair of hollow rubber blocks may be used to control the movement of the shackle 23. In a modification, a floating axle tube 51, Fig. 4, has its opposite ends connected to wheel support members 52. Trailing arms 53 are connected between the chassis and the members 52. Centrally of the vehicle a bracket 57, rigidly mounted on the tube 51, is supported on the vehicle frame 58 by means of a link 59 having pivotal connections 61, 62 to the frame and bracket respectively. Pivotal connections 61, 62 are mounted for limited resilient movements by springs 63, 64. In this embodiment braking and accelerating forces move the shackle 59 bodily against the reaction of springs 63, 64. To provide variable understeer in acceleration and braking, suspension arms 163, 164, Fig. 5, may be resiliently connected through pivots 161, 162, and springs 166 to the vehicle frame. The lower suspension arm 164 only may be resiliently connected to the frame. In a construction of the last embodiment, suspension arms 88, 89, Fig. 7, support an axle 86 from frame members 87. An air spring 95 and a shock absorber 97 are provided. The point 100 in which the axes of the spring 95, the shock absorber 97, and the suspension arm 88 meet is vertically above the axle 86. A resilient rubber block 102, having holes 106, 107 provides the connection between the end of the suspension arm 89 and the frame member 87. A metal reinforcement 108 is embedded in the block 102.

Filed: 1973-03-19
Abstract: 1370873 Digital data processing; radar HUGHES AIRCRAFT CO 19 March 1973 12991/73 Headings H4P and H4D A device for consecutively decoding and amplitude weighting groups of sequentially applied phase encoded signals, Fig. 9a (and continued in Fig. 9b, not shown) comprises a memory 200, to which the encoded signals are applied, and having a plurality of output circuits which are coupled to a plurality of processing subsections, e.g. 202 by weighting circuits, e.g. 210. Each processing subsection comprises: an accumulator 216 for providing, during each of a plurality of processing cycles, a subaccumulation signal that approximates the amplitude weighted phase decoded value of one subsequence of the applied phase encoded signals; a store 220 for storing the sub-accumulation signal; a multiplier 228 coupled between the store and the accumulator; and means, e.g. switch 212, coupling the accumulator output to the store input. The stored sub-accumulation signals are modified as a function of the amplitude weighted differences between one signal group and the next to form a new set of signals associated with the next group. The outputs from all subsections are combined in adder 226 to give the required decoded output. The arrangement includes a second channel 214, 221, 229, 217 in each subsection so that in one sequence one channel may be cleared while the other is used to decode the input data, and in the next sequence the roles of the two channels are interchanged. Although shown as single units, each unit of the decoder processes inphase and quadrature components of a received phase encoded signal, the various connections being multiple ones. In operation, the transmitter unit of a radar system, Fig. 6 (not shown), transmits a series of RF pulses, each of which comprises N<SP>2</SP> elements encoded to N discrete phases according to the Frank Code Fig. 3 (not shown). Encoding is providing by a phase shifter unit (70) which is controlled by a logic circuit (58). During the time between transmitted pulses, reflections from objects are received by the receiver unit, Fig. 7 (not shown), each reflector returning a similarly phase encoded signal which is demodulated in inphase and quadrature demodulators (92, 94). The operation of the demodulators are controlled by sampling pulses, and the resulting samples are stored in buffer stores (108, 110) before being shifted word-by-word into the decoding device (112) which applies the appropriate phase shifting and weighting factors to correlate one of the reflected signals, and decorrelate the others.
