Title: A system for detecting specified objects by radio waves
Inventor: BOJKO GEORGE
IPC: G08B13/24
Filed: 1964-11-05
Abstract: 1,030,537. Radar; radio receiving apparatus; valve oscillating circuits. PINKERTON ELECTRO-SECURITY CORPORATION. Nov. 5, 1964, No. 45165/64. Headings H3F, H3Q and H4D. [Also in Division G4] In an electromagnetic object detection system (e.g. an intruder alarm system) where a standing wave pattern of radio waves is set up by reflexion from the object thereby influencing receiving aerial impedance, a pair of aerials are spaced apart by a distance greater than the distance at which they respond substantially identically to changes in the standing wave pattern by change in position of the reflecting object, separate means sense impedance changes at each aerial with the output of one sensing means being inverted with respect to the other and the outputs of the sensing means are differentially combined. Spurious fluctuations in the system are cancelled and Doppler-type response is minimized. In the embodiment, Fig. 1 (not shown), an oscillator (2) feeds 400 Mc/s. energy into spaced aerials (4, 6) inductively via respective capacitors (30, 32). The aerials are connected, Figs. 3, 4 (not shown), via capacitors (72, 72a) to oppositely-poled rectifiers (76, 78) the outputs from which feed a differential circuit (74, Fig. 1) connected to a low-frequency amplifier. Oscillator, Fig. 1 (not shown). The oscillator consists of a self-excited twin-triode valve (16) of sufficient inter-electrode capacitance to afford signal feedback of correct phase and amplitude to sustain oscillation, the valve is in an earthed-cathode configuration with grid bias provided by a grid leak resistor (18), and the anode tank circuit inductance is a U- shaped wire (20) connected between the valve anodes, the tank circuit being tuned by changing the distance between the flat tuning disc (22) of a capacitor and the inductance. Aerial combined with receiving apparatus, Fig. 2 (not shown). The components in a circuit, Fig. 3 or Fig. 4 (not shown), are mounted within the insulated hollow hemi-spherical base of the corresponding aerial (60). Features relating to the reduction of the effects of interfering signals and to the independence of system sensitivity with aerial loading are described. More than one pair of aerials may be utilized. It is stated that changes in transmitted wave frequency caused by changes in aerial impedance leads to increased system sensitivity.

Title: Flow rate control apparatus for an hydraulic system
IPC: F15B13/04
Filed: 1965-10-26
Abstract: 1,105,117. Tractor power lift mechanism. INTERNATIONAL HARVESTER CO. 26 Oct., 1965 [Dec. 9, 1964], No. 45246/65. Heading A1P. A tractor power lift mechanism having position and draft control linkages, similar to those described in Specification 994,992, operating on a main control valve 58 is characterized by a fluid line incorporating a valve 76 which controls the rate of flow of pressure fluid both to and from the ram. With the valve core 56 in the "raise" position as shown in Fig. 4, pressure fluid entering the valve along line 79 is directed to the flow control valve 76 via line 212. The fluid returns to the main control valve via line 214 and passes along channel 90 where pressure is built up to move piston 139 off its seat and so open the conduit 145 to the ram. In the flow control valve (Fig. 6) the valve core 196 is manually movable to restrict the flow of pressure fluid through opening 195 whereby a differential pressure is produced on either side of piston 180 to move it against its adjustable spring bias in order to restrict the flow of fluid into the outlet passage 170 which supplies the fluid for operating the ram. Thus the rate of operation of the ram and hence the lifting rate is controlled. A compensating valve 120 is acted upon, on one side, by the incoming pressure fluid via passage 88 and, on the other side, by the pressure fluid passing to the ram through passage 90. Thus, if the flow control valve is restricting the passage of pressure fluid, the compensating valve will open to exhaust some of the incoming fluid and so prevent a pressure build-up. When the valve core 56 is moved to the right to the "lower" position, fluid entering along conduit 79 is directed out along conduit 230 to operate a by-pass valve whereby the pump output is fed straight to the sump. The part 148 of the core 56 unseats the ball valve 152 to allow fluid to flow from the back of piston valve 138 via chamber 118 to exhaust. Pressure existing on the front of piston 138 then moves this piston to open a fluid flow path from the ram 26, along passage 90 and through conduit 212 to the flow control valve. This restricts the fluid flow to control the rate of descent of the lift linkage before the fluid passes along conduit 214, passage 86 and conduit 222 to the sump 66.
