Title: Time multiplexer for high prf pulse doppler radar
IPC: G01S13/64
Filed: 1971-09-30
Abstract: 1351376 Radar WESTINGHOUSE ELECTRIC CORP 30 Sept 1971 [27 Oct 1970] 45565/71 Heading H4D A digital time multiplexer receives the output signals of the n range gate channels of a pulsedoppler radar receiver as inputs to a sampler unit 52, which has m output lines, and which is controlled by a synchronizer circuit 55. Each of the said m output lines is coupled through an analogue-to-digital converter 54 to a digital memory, comprising two memory units 58, 60 and a time sharing circuit 61. Sampling, which may be at least at the Nyquist rate, is carried out sequentially between successive transmitted pulses, and results in sequences of n digital words, each word relating to a particular range gate channel. Sequences are fed alternately into the memory unit 58 and into the memory unit 60. Each memory unit is associated with a respective digital-to-analogue converter 62, 64 and it is read out, by means of a memory select switch 66, whilst the other memory unit is receiving an input. The output from the switch 66 is taken through a filter and amplifier 68 to a single doppler filter bank. There is a delay of one pulse repetition period in the analysis of the pulsed doppler radar signal and an effective multiplication of all frequencies, such that the bandwidths are a minimum of n times the originals. An associated pulse-doppler radar receiver is described (Fig. 1, not shown) in which a stable local oscillator is coupled both to a transmitter R.F. amplifier and to a receiver mixer. The R.F. amplifier is pulse modulated at a frequency which is varied in a pre-determined manner under the control of a master synchronizer. The mixer feeds the range gate channels through a distribution amplifier having n outputs. Each channel comprises, after its range gate, a band pass filter, a zero doppler notch filter (for excluding altitude line clutter in an airborne installation), means for tracking and rejecting main beam clutter, and a doppler amplifier feeding the multiplexer.

Abstract: 1350706 Inductive control systems WAGNER ELECTRIC CORP 22 March 1972 [24 March 1971] 47287/72 Divided out of 1350705 Heading H4U A key-operated electronic control circuit for operating door locks V and VI and the power control circuit VII of a vehicle as described in Specification 1,350,705 comprises a tank circuit L 1 , C 2  which is responsive to the juxtapositioning of a key circuit, Fig. 2, to suppress its resonance, to thus release the lock of at least one door by means of solenoid SOL1, and at the same time the control circuit enables the engine to be started if starting switch S8 is closed within a certain time of the unlocking sequence. On closure of a key-operated switch S1, power is fed to the oscillator I. This is rectified at II, and amplified at III and IV. In this last stage, a transistor Q4 is maintained normally conductive thereby earthing the base of transistor Q5 to make it non-conductive. This prevents energization of relay K1. However, when the key circuit is placed in position, the base of transistor Q5 is energized, enabling current to reach relay K1 to operate its contacts. This lights an indicating lamp Il and current passes to the power control circuit VII, and through N.C. test switch S2 and capacitor C9 to momentarily energize relay K2 and the unlocking solenoid SOL1, and the locks of other doors, if desired, to give access to the vehicle. The key circuit need not include resistor R19, and the tank reactor L1 may be divided into two series components (Fig. 3, not shown).

Abstract: 1,020,077. Pile driving. RAYMOND INTERNATIONAL Inc. Dec. 2, 1963 [Dec. 10, 1962], No. 47557/63. Heading E1H. [Also in Division B3] A pile driving hammer comprises a cylinder 12, piston 13, connecting rod 14 secured to ram 11, a cam 32, 33 linked to said ram, a rotory cam follower 28 oscillated by said cam and a slide valve 18 having an arm 18a linked to cam follower 28 for reciprocation thereby between a pair of valve actuating positions. Hydraulic fluid passes from pumps 41, 42 through valves 50, 51 into pressure line 55 connected to pipeline 15 which passes the fluid into distribution box 16. From box 16, pipe 17 leads to cylinder 12 below piston 13, pipe 21 leads to an inlet accumulator 22 precharged with gas to a pressure two-fifths that of the hydraulic fluid supplied over pipeline 15, and pipe 20 leads to slide valve 18. From valve 18 pipe 23 extends to the top of cylinder 12 and drain pipe 25 extends to an outlet accumulator 27 precharged with gas to 100 p.s.i. When the piston 13 rises, the cam follower 28 is rotated clockwise and through linkage 29, 29a, 30 and 18b pushes arm 18a to the left which allows pressure pipe 20 and pipe 23 to communicate and pressure fluid to enter the top cavity of the cylinder. This forces the piston 13 down which rotates the cam follower anticlockwise and moves arm 18a to the right which allows pipe 23 to communicate with drain pipe 25 and thus the pressure on top of the piston is removed and the piston rises again under fluid pressure from pipe 17. When the piston rises and the valve 18 is actuated to reverse the piston, this reversing effect does hot act immediately since the piston accumulates a considerable velocity in its upward travel, and therefore while it continues to rise will discharge liquid from the upper cylinder cavity through pipe 23 into box 16 where most of it will go through pipe 21 into accumulator 22. The accumulator 22 is 5 to 20 times the cylinder volume. The valve 18 is designed with an overlap between its two actuating positions. The cylinder 12 is suspended by a universal coupling from plate 60 and piston rod 14 is connected to ram 11 by means of knob 83 and rings 93 and 94 (Fig. 3, not shown).

[Also in Division G1] In an electrical measuring device four transducers e.g. strain gauges, are connected to form a bridge 9, Fig. 1, having the output diagonal connected in opposition with that of a second compensator bridge 10 through an amplifier 15 controlling a servomotor 14 which moves a sliding-contact 13 of a potential divider or potentiometer 12 until the two bridge outputs balance when the position of contact 13 indicates the output voltage of bridge 9. The input diagonals of bridges 9, 10 are fed by current transformers 5, 6 whose primary windings 3, 4 are connected in series with a low-resistance A.C. source, whereby the excitation currents of the two bridges have a constant magnitude ratio. Alternatively, the device comprises a single current transformer, Fig. 6 (not shown), whose secondary winding energizes the transducer bridge, whereas the primary winding energizes the second bridge or vice versa. Rectifiers may be included in the secondary circuits of the current transformers and a plurality of bridges formed by transducers may have their outputs connected in series each bridge being fed by a separate current transformer, Figs. 2, 3, 4 (not shown).
