Title: Waste compactors
IPC: B30B9/30
Filed: 1973-06-21
Abstract: 1370856 Refuse compactors; filling bags R G DIXON & CO Ltd 21 June 1973 [21 June 1972] 29018/72 Heading B8C  A waste compactor comprises a ram and a drive arrangement operable to reciprocate the ram into and out of a container to compress waste material therein, the ram having a bottom opening to permit waste material inserted in the compactor at a level above the opening to pass through the ram into the container, and a closure assembly which closes the opening before the ram compresses the waste material in the container. As shown, a housing 1 houses a box-like ram 2 and a removable bin 3. The ram is supported by three feed screws 4 supporting ram frame members 8 and is reciprocable vertically by a reversible motor 9 which is connected by a belt 13 to one of the screws 4 from which the drive is transmitted to the other screws 4 by a further belt 14 through pulleys 15. An access door 16 allows waste to be passed through the ram and into the bin 3, the ram being provided with doors 17 which are automatically, opened by gravity or by door-operating mechanisms 18, Fig. 4, as the ram approaches the limit of its upward stroke. As the ram moves downwardly the doors 17 close automatically. In use, the ram is moved to its lowest position, waste is inserted through the door 16 and a shoot 30, the door 16 is closed and the ram then moves upwardly automatically, the doors 17 open to release the waste into the bin 3 and the ram then descends to compress the waste until a sensing device 32 is operative to stop the motor 9. The sensing device comprises a pivoted lever 34 on one end of which is held in engagement with a rum 37 of belt 13 by a spring 28, such that as tension in the belt rum 37 increases under loading of the ram the lever 34 is pivoted against the tension of the spring 38 to actuate a microswitch to stop the motor. A micro-switch 38 actuates a warning lamp 40 to indicate that the bin 3 is full. A full bin is removed by actuation of an unload button 42 to move the ram upwardly out of the bin, when the motor is automatically switched off and the bin may be withdrawn. Preferably the bin is lined with a removable plastics bag. A micro-switch 44 prevents operation of the motor in the absence of a bin 3. Rubber blocks 45 between wheels 43 of the bin and the underside of the bin prevent excessive loading on the wheels by the ram.

Title: Improvements in or relating to radar systems
IPC: G01S7/288
Filed: 1952-11-21
Abstract: 735,769. Radiolocations. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Nov. 21, 1952 [Dec. 1, 1951], No. 29529/52. Class 40 (7). In a phase modulated radar system the output of a V.H.F. oscillator which is phase modulated to provide the radiated signal is combined in an unmodulated condition with the received echo signals to produce a signal which is employed to display the target. The general arrangement is shown in Fig. 1 and comprises a V.H.F. oscillator 5 which supplies a continuous sinusoidal oscillation to the transmitting aerial 1, via waveguides 60, 61, 63 and phase modulator 3 and to a detector unit 7, via a coupling device 6 and waveguide 62. Echo signals received by aerial 2 are mixed in unit 7 with the energy fed thereto via waveguide 62 and the output from 7, which is a low-frequency voltage, is fed to a device 8 which selects the echoes and supplies an output signal to one set of deflecting plates of tube 9 the other coordinate of deflection of which is supplied by the modulating signal from source 4. The nature of the device 8 depends on the form of the modulating signal from source 4 two main forms of which are considered: (a) that in which the modulating signal comprises pulses of short duration; and (b) that in which the modulating signal comprises a sinusoidal wave frequency-modulated according to a sawtooth law. For case (a), in which the phase of the transmitted (and received) wave is impulse modulated, the device 8 comprises a low-pass filter 81 (Fig. 4), adapted to select the Doppler frequencies due to echoes from moving targets and a bandpass filter 82 the pass-band of which does not overlap that of filter 81 and which selects low-frequency signals due to phasemodulated wave echoes, both filters being fed from terminal a<SP>2</SP> of detector 7 (Fig. 1), and the output of filter 81 being employed, after amplification in 83, to control a " gated " amplifier 84 which is " opened " in response to echoes from moving targets and supplies a display signal via terminal a<SP>1</SP> to tube 9 (Fig. 1). For case (b), in which the transmitted (and received) wave is phase-modulated and the frequency of which varies in accordance with a sawtooth law, the device 8 comprises a low-pass filter 85 (Fig. 5), feeding a mixing circuit 86 to which is also fed a sinusoidal wave (from generator 89) frequency-modulated by a sawtooth wave derived from terminal a<SP>3</SP> (Fig. 1) which is connected to terminal a<SP>7</SP> (Fig. 5), and the output of mixer 86 is then supplied via a low-pass filter 87 and amplifier 88 to the oscillograph 9 (Fig. 1) to produce the required display. The Specification includes a mathematical treatment of the operation of the invention.

Title: Improvements in or relating to power transmission systems
IPC: B30B15/16
Filed: 1939-11-10
Abstract: 533,478. Hydraulic power transmission. VICKERS, Inc. Nov. 10, 1939, No. 29783. Convention date, Nov. 18, 1938. [Class 69 (ii)] In a hydraulic power transmission system in which a pump operates a fluid motor for actuating the ram of a hydraulic press, or a shear, punch or the like, a control means is provided which can be set to permit a single cycle or a repeated cycle of operations of the machine, and in addition an emergency stop mechanism is provided which can stop the machine quickly whether on its advancing or return stroke. As shown the platen 46 of a hydraulic press is actuated by a motor comprising a cylinder 40 and piston 42, which is driven by liquid supplied by an electrically driven pump 10 connected by a suction pipe 16 to a tank 14 and a pressure pipe 18 to a control valve 26 which is set to supply pressure liquid to the cylinder 40 via a pipe 36 for the downward stroke of the piston and via a pipe 38 for the upward stroke. The valve 26 is fitted with pistons 68, 70 at either end, and the liquid acts on these pistons to control the position of the valve. Adjustable check valves 80, 82 control the rate of movement of the pistons. In the control position of the valve 26 a detent 94 prevents movement of the valve to the right under pressure of liquid on the piston 70 on the left end of the valve spindle. In this position the liquid from pipe 18 enters a port 24 and moves past the bevelled parts of a land 62 and returns via port 28 and pipe 30 to the tank. On moving the shaft of detent 94 clockwise by means of a lever 98 the valve moves to the right and liquid passes through ports 24, 32 and pipe 36 to the upper part of cylinder 40, and returns via pipe 38, a piston valve 50 which opens against the action of a spring 52 to permit return of liquid to tank 14 via pipe 38, ports 34, 28, and pipe 30. To reverse the flow of liquid a pilot valve 100 is operated by means of an adjustable tappet 116 carried by the platen 46, or by means of a spring-controlled piston 122 in a pipe 128 which can be connected by a valve 130 to the pressure pipe 36, the piston 122 operating to rotate the valve 100 through 45 degrees when the pressure reaches a given value. In either case rotation of the valve 100 directs the liquid pressure to the right end of the valve 26 and by acting on the piston 68 the valve 26 is reversed by being moved to the left. The pressure pipe 18 is then connected via ports 24, 34 to the pipe 38, and the liquid flows past a check valve 56 in the valve 50 to the lower end of the cylinder 40. If the lever 98 is returned to the position shown the platen 46 is given one reciprocation only, but if it is retained in the adjusted position the motor 40, 42 continues to operate. By operating ari emergency valve 134 by means of a lever 136, which is normally maintained by a spring 138 against a stop 140, the actuation of the motor 40, 42 can be stopped at any time.
