Filed: 1973-09-28
Abstract: 1401921 Hydraulic circuits TELDIX GmbH 28 Sept 1973 [12 Oct 1972] 45486/73 Heading F1P [Also in Division F2] A normally closed valve 16 connects respective output lines 1, 2 from two pumps 3, 4, and opens in response to means detecting that pressure in one of the lines has fallen below a predetermined value. Hydraulic accumulators 9, 10 operate respective switches 11, 12 such that the switches are open if the pressure in the accumulators falls below the predetermined value, the outputs passing through an AND gate 13 to control a common drive 5 to the pumps 3, 4 to stop the drive when the switches are closed. The outputs pass to an OR gate 17 with negated inputs so that if either switch 11, 12 is open, the valve 16 is actuated; a pulse extending timing element 19 extends the response time. However, the signal passes to the valve 16 only if fluid level in a reservoir 6 is above a given level, an AND gate 18 accepting the signals from the element 19 and from a level indicator 20. If a continuous drain occurs in one line 1 or 2, due to a leak, a wall 24 in the reservoir 6 separates the supply for each line, so that the valve 16 remains closed. A warning indicator 23 is actuated with the valve 16 through a pulse delaying element 21 and a bi-stable element 22.

Title: Conjugated diene polymers
IPC: H04Q1/45
Filed: 1963-11-19
Abstract: Rubbery polymers are made by polymerizing a C4 to C10 conjugated diene alone or in admixture with another monomer in the presence of an organometallic or metal hydride catalyst and controlling the molecular weight of the product by charging initially to the polymerization zone only a portion of the total monomers to be used togehter with the initiator, allowing polymerization of this initial charge to proceed until 20 to 50% conversion has been attained, then charging the remainder of the monomeric material in at least one additional increment, and continuing the polymerization until a polymer of the desired molecular weight is obtained.  The polymerization is preferably effected in a hydrocarbon diluent.  The conjugated diene may be butadiene, isoprene, 2,3-dimethyl-1,3-butadiene, 1,3-pentadiene, 2-methyl-, 2,3-dimethyl-, or 3-methyl-1,3-pentadiene, or 2-phenylbutadiene. The other monomer may be ethylene, propylene, 1-butene, 1-hexene, 1-octene, isobutylene, 2-olefines, di-non-conjugated- or multi-olefines, cyclohexene, styrene, acrylonitrile, methacrylonitrile, methyl acrylate, methyl methacrylate, 5-methyl-2-vinylpyridine, 2-vinylpyridine, 4-vinylpyridine, 3-vinyltoluene, 1-vinylnaphthalene, 2-vinylnaphthalene, or 4-vinyltoluene. The Specification contains a long list of suitable catalysts for making cis- or trans-polymers. Preferred catalysts are formed by mixing an organo-aluminium compound, e.g. triisobutyl-aluminium, with TiI4, TiI4+TiCl4, or TiCl4+I2. The polymers are recovered by known techniques, e.g. addition of methanol.

Title: Improvements in or relating to motor vehicles having liquid cooling systems
Inventor: BOOTH JOHN CECIL HOGARTH
IPC: G01F23/24
Filed: 1964-11-09
Abstract: 1,107,000. Liquid level indication. THOMAS ELECTRONICS Ltd. Dec. 14, 1965 [Nov.9, 1964], No.45659/64. Heading G1H. In a method of, or device for, detecting a low liquid level in a reservoir, such as a vehicle radiator, an emitter of a transistor TR 1  is biased to - 12 volts with respect to earth by means of a low resistance potential divider R 2 , R 3  and the base of the transistor is connected to the centre point of a potential divider R 1 , R x  where R x  is the resistance to be measured between an electrode, extending into the reservoir, and the reservoir body. When the liquid level falls to, or below, a minimum level, R x  reaches a high value and a lamp 2 is lit and when the electrode is immersed in liquid the lamp 2 is extinguished, or partially illuminated, depending on the voltage between the electrode and the reservoir body. Other circuits are described using two or more transistors but in each case the transistors have three terminals, one of which is controlled by the resistance to be measured and also in turn controls the current passing between the other two terminals.
Patent GB-1490866-A (GB)
Title: Light responsive detectors
IPC: G08B17/107
Filed: 1974-10-22
Abstract: 1490866 Smoke detectors CHLORIDE BATTERIJEN BV 22 Oct 1974 [26 Nov 1973 8 March 1974] 45706/74 Heading G1A A device responsive to a predetermined situation e.g. the presence of smoke, has a pulsed light source and a light detector whose output is connected to a threshold circuit such that a signal is delivered to an alarm only if the detector output exceeds a given level. The light source is pulsed to that it is typically emitting only for 20Á secs every 2 secs, and the level detector is also energized only during the time the source is pulsed; this reduces the likelihood of external light flashes affecting the device. In Fig. 1 the source is an LED, pulsed as above by a power supply P. The pulse from P also activates the threshold circuit L and operates switch S1 to disconnect that circuit's input from earth. The light emitted by the source is scattered by any smoke present to a detector C; the detector pulse passes via capacitor F to amplifier A and thence to the threshold circuit L. The capacitor prevents slow changes in ambient light being amplified. The threshold circuit compares the amplified pulse with a level pre-set by R2, and delivers a SET signal to flip-flop FF if that level is exceeded. At the start of the next power supply pulse the flip-flop is reset by a signal from differentiator D. The flip-flop can either activate an alarm K directly, or, as shown in Fig. 1, via an integrator T whose time constant is such that two consecutive pulses are required from the flip-flop before the alarm is activated. Power supplies: it is desirable to isolate the detector circuitry from the light source power supply. In Fig. 4 the power is supplied on line V1, and the pulse supply P activates a switch S2 as well as the light source and threshold circuit. During light emission the circuitry thus receives its power from a capacitor F1 which is recharged via R when S2 is closed at the end of each pulse. This use of a switch may be combined with or replaced by the use of smoothing chokes feeding capacitors F1, F2, as in Fig. 5 (not shown), or by resistors and Zener diodes feeding those capacitors, as in Fig. 6 (not shown).

Filed: 1970-09-30
Abstract: 1317625 Variable reactance circuits, transistor amplifiers RCA CORPORATION 30 Sept 1970 [1 Oct 1969] 46438/70 Headings H3R and H3T A reactance, variable in response to a control signal comprises: a reactance 10; a circuit 20 for sensing the current through the reactance; and an amplifier 30, 40, having a gain dependent on the magnitude of the control signal 25, and being arranged to amplify the output current from the sensing circuit 20 and feed it back in parallel with the reactive element. The reactive element 10 may be the inductance of the resonant circuit 10, 12 of an oscillator which includes a positive feedback amplifier 14. A similar control circuit may be employed to vary the capacitive reactance, the two control signals being applied in push-pull, Fig. 4, (not shown). As shown, the output stage 40 of the current amplifier comprises a splitter, whose gain is varied by the control signal. In a modification, Fig. 5, (not shown), two splitters (40a, 40b), each controlled by push-pull control signals, are connected in cascade. Current amplifier and sensing circuit.-Variation in current at point 18 varies the current through resistor 228, the resulting change in potential across the resistor being fed back via transistor 234 to the base of transistor 224, thus varying the conductivity of transistor 224 to maintain the current through transistor 222 constant. The varying base potential of transistor 224 is also applied to the base of transistor 310 to produce a collector current I s  which has a relationship to the magnitude of the collector current of transistor 224 in proportion to the relative base-emitter areas of the two transistors. As shown the collector current of 310 is one fourth that of 224 by virtue of the quadruple emitters of the latter. Transistors 310, 224, may be thermally coupled. In a modification, Fig. 3, (not shown), the circuit 20 is replaced by a single common emitter stage.

Abstract: 979,944. Seaming non-metallic sheet material. AQUARIUS GEB. Dec. 17, 1962 [Aug. 25, 1962], No. 47497/62. Heading B5K. [Also in Division B8] The sealing jaws 8, 9 (Fig. 3), for forming transverse welds across a hot-sealing foil tube to produce sachets are moved into engagement by one or more hydraulic rams with their cylinders 18 connected to the sealing head 9 and their pistons 19 connected to the counter head 8. In the form illustrated the counter head 8 is connected through springs 22 to a member 24 carried by the piston rods 20 and supporting a knife 12 for severing the sachets. Thus an initial pressure rise in the cylinder 18 brings the heads 8, 9 together, against the bias of springs 27, to effect sealing, and a further rise in pressure subsequently forces the blade 12 into a slot 60 in the head 9. The initial hydraulic pressure to effect welding is provided by a pump barrel 36 (Fig. 4), operated by a cam 32 to produce a pressure in the operating conduits 30 determined by a relief valve 43. The subsequent higher pressure to effect severing is produced by a further pump barrel 47 operated by a cam 56 and is terminated either when a further cam 54 releases a valve 52, or when a solenoid-operated valve 49 is opened under the control of a photocell which senses markings on the foil. The cam 32, 56, 54 can be changed to produce sachets of different sizes. The transverse welding heads 8, 9 (Fig. 3), are mounted for movement on a vertical support 13 so that they serve to draw the foil downwardly. The foil is tubed around a spout delivering material (Fig. 1, not shown), and is longitudinally welded while on the spout.
