Abstract: 1,184,454. Power assisted and telemotor steering systems. ROBERT BOSCH G.m.b.H. 6 April, 1967 [9 April, 1966], No. 15761/67. Heading B7H. [Also in Division F1] A steering cylinder 82, Fig. 4, is connected. in closed circuit with a reciprocating Hydraulic machine 1, see Group F1, which is operable as a pump by a steering wheel 12 to actuate the piston 83 and steering linkage 85 or is operable as a motor to rotate the steering wheeL by movement of the wheels 86 transmitted to the piston 83. The steering cylinder 110, Fig. 5, is connected to the connections of the machine 1 via a control valve 89 which also controls the connection of the machine and steering cylinder to a motor driven pump 87 and a liquid reservoir 101, respectively, to provide power assistance. The spool 121 of the control valve is biased by a spring 144 for limited movement to either side of the neutral position illustrated by the pressure applied to its opposite ends. In the neutral position the pump 87 merelydelivers to the reservoir via recesses 93, 96 and 94, 97 in-the spool housing 91 and the steering cylinder connections 106, 107 connect directly to the connections 140, 141 of the machine 1 via passages in the control valve 89. When the pressure from the machine-1 1 operated as a pump by steering wheel 12 is sufficient to move the spool 121 against spring bias in the direction corresponding to steering- wheel movement, the suctionconnection 140 or 141 of the pump is connected to the output of the pump 87 via recess 93 and spool passages 130 and 128 or recess 94 and spool passages 131 and 129. One side of the steering cylinder 110 is therefore subject to the pressure of the pump 87 increased by the pump 1. The remaining side of the steering cylinder 110 is connected to the reservoir 101 via recess 96 and passage 104 or recess 97 and passage 105. With the pump 87 inoperative and the spool 121 moved from its neutral position a check valve (150), Fig. 6 (not shown), provides for the connection of the recess 93 or 94, connected to the pump 87, to the reservoir 101. If shocks occuring at the wheels 114 create pressures in the steering cylinder connections 106, 107 sufficient to displace the spool 121, the cylinder connections are connected to the reservoir 101 via spool passages 128 and 130 or 133, 129, 131, recess 115, spring-loaded check valve 118 and recess 97.

Abstract: 1,218,622. Track apparatus. GENERAL ELECTRIC CO. 3 April, 1968 [5 May, 1967], No. 16078/68. Heading B7N. [Also in Division H4] An object identification system comprises a transmitter, Fig. 1., including an oscillator 19 providing a signal which is swept from 480 kc./s. to 450 kc./s. and is applied to a device 21 containing four piezo-electric elements resonant at 450 kc./s., 460 kc./s., 470 kc./s. and 480 kc./s., respectively. The output of the oscillator 19 also is supplied direct to the transmitter 23 and transmitted via a coil 29 to a transponder 10 carried by the object to be identified. As shown, the transponder includes two piezoelectric elements 15, 17 so that it has a low impedance at the two corresponding frequencies, e.g. 480 kc./s. and 460 kc./s., which are retransmitted as an identification number in binary form, the resulting oscillations having a slow decay rate. The four frequencies from device 21 are applied to a sequencing circuit 25 which controls a switch 36 to turn on the transmitter for a period of 500 microseconds at the start of each of the four frequencies and at the end of each period to switch off the transmitter and turn on the receiver 27 for a period of 150 microseconds. The output of receiver 27 is supplied via amplifier 31 to a discriminator 32 which also receives a sweep signal from oscillator 17 differing by 15 kc./s. from the sweep signal supplied to the transmitter. The resulting 15 kc./s. difference frequency is supplied to a digital detector 33 and logic circuit 34, Figs. 2 and 3 (not shown), which (a) provide a digital signal which switches on and off at the frequency of the input providing the input frequency is in the correct tolerance range and (b) provide an output only if the input signal is a true A.C. signal, thus eliminating noise signals. The signals passed by the logic circuit 34 are stored temporarily at 35 and read out either when the received signals cease for more than one sweep, or after a predetermined number of sweeps.
