Title: Telescopic Suspension Units
Inventor: CHELL PETER JOHN PEARSE
IPC: B60G17/048
Filed: 1967-11-09
Abstract: 1,187,599. Springs. VAUXHALL MOTORS Ltd. 24 Oct., 1968 [9 Nov., 1967], No. 51014/67. Heading F2S. In a telescopic suspension unit an outer casing 20 of a telescopic damper is sealingly connected to a cylinder member 36 to form a variable-volume chamber 48. The damper has flow-control valves 30, 66 arranged so that reciprocatory movement of a damper piston 10 in a cylinder tube 16 of the damper causes hydraulic fluid to flow from a reservoir space 22 within the outer casing 20 into the chamber 48, via the tube 16. The return flow of hydraulic fluid from the chamber 48 to the reservoir space 22 is controlled by a reservoir supply valve 72 which is open when the length of the unit exceeds a design value and is closed by a valve control member 76 when the length of the unit is less than the design value. In an embodiment the outer casing 20 is connected to the cylinder member 36 by means of a tubular rolling diaphragm 34; the valve control member 76 is urged by a spring 80 towards an annular projection 84 formed in the cylinder member 36; flow-damping valves 50, 52 are provided between the chamber 48 and a pipe 54 which connects to a separate displacement chamber 56, Fig. 2, having a rubber diaphragm 62 therein which divides the chamber 56 into a gas chamber 64 and a fluid chamber; the damper piston 10, Fig. 1, carries one-way damper valves 12, 14 and is reciprocable by means of a piston-rod 18; an annular resilient bump-stop 32 is provided in the cylinder tube 16; and a gas chamber 26 is formed within the cylinder tube 16 by means of flexible diaphragm 24. The unit has a self-levelling action. As the vehicle travels over relatively small undulations, the piston-rod 18 is reciprocated and hydraulic fluid is pumped from the reservoir space 22 to the chamber 48. During a bump-stroke the piston 10 moves towards the valve 30 and has its one-way valve 14 open to allow fluid to flow from chamber 28 to chamber 68. During rebound-stroke the piston 10 displaces fluid from the chamber 68, through the flow control valve 66 into the chamber 48, the valve 30 opening to allow fluid to flow from the reservoir space 22 to the chamber 28. In a modification the spring 80 may be replaced by pressurizedgas.

Title: Doppler radar systems pulsed doppler radar systems
IPC: H03D3/00
Filed: 1973-11-16
Abstract: 1455832 Pulse doppler radar SIEMENS AG 16 Nov 1973 [17 Nov 1972] 53173/73 Heading H4D A Doppler radar system converts echo signals to digital form and supplies them to two parallel channels each containing a digital mixer, the mixers having different heterodyne frequencies, followed by respective digital low pass filters, having the same cut-off frequency, the channel outputs being fed to a comparator stage, the output of which is fed to a control circuit which generates control signals to lower the cut-off frequencies of the low pass filters and alter the heterodyne frequencies of the mixers. The arrangement enables a sequential narrowing of the system Doppler pass band around the received echo Doppler frequency. An antenna RA, Fig. 1 emits RF pulses supplied by transmitter ST, the echoes being passed to receiver ET. After being mixed the Doppler signals are passed to analogue to digital converter W feeding two channels UK1, UK2. Each channel comprises a digital oscillator 01,02, a digital mixer M1,M2, a digital low pass filter TP1,TP2, and a squaring stage B1,B2. An inverter IV1 is placed in channel UK1 and the inverted signal is passed to comparator AD together with the signal from channel UK2. A control device AS operates on the low pass filters and oscillators in response to the output of the comparator. In Fig. 2, the frequency characteristics DK1,DK2 of channels UK1,UK2 are shown together with frequencies f01,f02,fD of the oscillators 01,02 and the Doppler signal respectively. The low pass filters are initially given a cut-off frequency of e.g. 2 KHz by control AS and this, together with the mixers M1,M2 results in a pass band B of 4 KHz about frequencies f01,f02. Doppler frequency fD is for example 16À2 KHz and produces a relatively large signal S1 and a very small signal S2 at the outputs of channels UK1, UK2 respectively, f01,f02 being 15 and 11 KHz respectively. In the example, fD-f01=1À2KHz, fD-f02=5À2 KHz. Comparator AD therefore detects S1 is greater than S2 and control AS increases frequencies f01,f02 to 17 KHz (f01<SP>1</SP>) and 14 KHz (f02<SP>1</SP>) and lowers the cut-off frequencies to 1À5 KHz. This gives a band pass B<SP>1</SP> of 3 KHz and f01-fD=0À8 KHz, fD-f02<SP>1</SP>= 2À2 KHz. S1,S2 are again compared and AS alters the frequencies f01,f02 and cut-offs accordingly. In this case, the heterodyne frequencies are again increased to f01<SP>11</SP> = 17À4 KHz, and f02<SP>11</SP> = 15 KHz and the cut-off frequencies are lowered to 1À2 KHz, giving a band pass B<SP>11</SP> of 2À4 KHz, f01<SP>11</SP> - fD being 1À2 KHz and fD - f02<SP>11</SP> also being 1À2 KHz. Signals S1,S2 are now equal and doppler frequency fD is within the much narrower band pass filter characteristic. This enables a more accurate determination of fD and improves the signal to noise ratio. Frequency fD is indicated by device AF. Detailed circuitry suitable for oscillators 01,02 and filters TP1,TP2 is given.

[Also in Division B7] A storage installation comprises a fixed shelf unit 8 and a plurality of wheeled shelf units 1-5 arranged in a row and movable on rails 7 so that a service passage may be provided selectively between any two adjacent units, an end unit 1 being provided with a reversible electric motor 9 driving a wheel 6 and the installation including an electric control circuit remotely operable to effect selective coupling and uncoupling of adjacent units 1-5. The coupling devices may comprise pairs of electromagnets 14-18 which co-operate with magnetisable plates (19, Fig. 3) on adjacent units. Alternatively (Fig. 5), a mechanical coupling is effected by interengagement of a pin (50) on one unit and the hooked end (48) of a two armed lever (44) which pivots under the control of an electromagnet (47). In use, to create a service passage between units 4 and 5 from the position in Fig. 1, a push button switch 28 on the unit 4 is pressed and held to power the motor 9 so that units 1-3 are advanced to unit 4. The switch 28 is in parallel with similar switches 25-27 and 29 on other units. When the unit 3 reaches unit 4 a limit switch (13) effects a reversal of the motor 9 with the switch 28 held depressed. Simultaneously, electromagnets 14-16 are energised to affect a coupling of the units 1-4 which move away from unit 5 until operation of a limit switch (12) stops the motor 9. A safety switch (23) is actuated to stop the motor 9 by a pivoted guard rail (22, Fig. 3) when the latter meets an obstacle.

Abstract: 1,242,594. Cylinders. A. FUNICIELLO. Nov.13, 1968 [Nov.24, 1967], No.53723/68. Heading F1B. In a two or four-stroke I.C. engine, a cylinder provided with at least one combustion zone and at least one squish zone formed between the piston crown and the cylinder head, has at least two ignition means. In the embodiment shown an engine cylinder having at least two valves (not shown) has two combustion zones 16, 17 and two spark plugs 8, 9. After ignition, combustion is completed in the smaller zone 17 before it is completed in the larger zone 16. The resulting higher pressure in the zone 17 before completion of combustion in zone 16, forces unburnt mixture trapped in the squish zone into the zone 16 for combustion thereof. In an alternative arrangement in which the combustion zones 16, 17 are of the same or different volume, the ignition is advanced in one of the combustion zones to provide the differential combustion. In other arrangements there are more than two combustion zones, or only one combustion zone. In the latter case one of the spark plugs is located at the combustion zone and the other is located at a portion of the squish zone and is arranged to spark in advance of the combustion-zone sparkplug. The combustion zone spark-plug can be located in the combustion zone or at the edge of the squish zone adjacent the combustion zone.

[Also in Division H1] A battery plate grid is made by placing a conductive plate lug 16 having an integral extension 17 of lead in a mould containing an impression of the grid, filling the mould with particles of synthetic resin, such as polyvinyl chloride, heating without pressure to cause the particles to adhere to one another such that extension 17 is trapped by the resin, removing the grid from the mould and rendering the grid conductive, e.g. by coating with molten lead or lead alloy. The resin particles may be heated to such a temperature that entrapped air is driven off leaving the resin grid with a substantially non-porous inner region and a pitted surface, and the conductive coating then enters the indentations of the pitted surface. In a continuous process, Fig. 3, a conveyer 18 carrying aluminium moulds 19 each containing an impression of battery plate grids first pass through a filling station 21 where a lead member constituting a pair of interconnected battery plate lugs is inserted into each mould, the rest being filled with P.V.C. particles.

[Also in Division D1] A web-reel support comprises a fixed post 5 upon which is keyed a sleeve 7 having a conical portion 8. The reel 11 is clamped on a sleeve 17 between a plate 19 and packing rings 21 and 22 by a retaining nut 18. An inner sleeve 24 screwed to the sleeve 17 has a recessed portion in which the outer ring 25 of a ball-bearing 14 is retained by a locking ring 26. The inner ring 13 of the bearing 14 is held against the conical portion 8 when a pawl 28 of a brake plate 27 with a lining 30, is slid over sleeve 7 to engage ratchets 29. The sleeve 7 can be moved axially on the post 5 against the force of spring 9 by a hand nut 10, thereby transversely registering the reel 11. With this arrangement, the pressure between the retaining nut 18 and the brake lining 30 varies proportionally with the weight of the web-reel, thereby controlling the web tension as the web roll diameter decreases.
