Title: Motor vehicle battery charging system
IPC: H02J7/14
Filed: 1975-04-11
Abstract: 1499176 Battery charging systems DUCELLIER ET CIE 11 April 1975 [24 April 1974] 38989/77 Divided out of 1499175 Heading H2H A motor vehicle battery charging system includes an indicating lamp which is illuminated under two conditions which are when the battery charging voltage exceeds a predetermined value and when the output voltage of the vehicle alternator is less than the battery voltage. A vehicle battery is charged from an alternator 1 by way of a rectifier bridge 5-10, the field winding 16 of the alternator being excited by way of diodes A, B, C and a voltage regulator 15. Closure of a switch 14 causes the vehicle engine to drive the alternator 1 and applies the battery voltage to a resistive potential divider 20, 21 such that whilst the output voltage of the alternator is below the battery voltage a lamp 17 is illuminated by way of a diode 25, the regulator 15 and field winding 16. When the alternator output voltage increases to equal the battery voltage the diode 25 becomes non-conductive and the lamp 17 is extinguished. Should the alternator output voltage increase beyond a predetermined value due to a malfunction of the regulator 15 of an earth connection interrupted, breakdown of a zener diode 22 will occur to render the transistor 19 conductive and the lamp 17 illuminated to indicate the irregularity. A resistor 27 connected between the lamp 17 and the positive terminal of the divider 20, 21 has its value so chosen that the circuit bounded by terminals IND; L; + ; -, may be suitable for inclusion in an existing system.

Abstract: 937,207. Interrupters. C. S. DOUGLAS. Dec. 1, 1960 [Nov. 20, 1959], No. 39393/59. Class 38 (5). The relative durations of open and closed conditions of a cyclic switch for controlling input of energy to electrical appliances are varied by adjustment of the position of an otherwise-stationary switch unit with respect to a continuously running cam which acts on a switch-operating lever made of bimetal to compensate for changes in ambient temperature. In the embodiment of Fig. 1, a micro-switch 6 is pivoted at 5 on a plate 1 and its bimetal operating arm 7 is urged by a spring 9 into contact with a cam 3 driven by motor 2. Spring 9 also presses switch 6 against a screw 10 which is threaded in a bush 11 on plate 1 and is adjustable by a knob 12 with a pointer (not shown) moving over a scale 13. In another embodiment (Fig. 3), a motor 17 drives cam 18 to operate bimetal arm 27 of micro-switch 26 which is mounted on a plate 19 pivoted to a base-plate 16 at 20 and guided by pins 22 in slots 21. A spring 25 urges plate 19 counterclockwise with respect to plate 16 to engage a cam 23 thereon. Cam 23 is adjustable by spindle 24 to move plate 19, and hence switch 26, to vary the on/off ratio of the switch operation.

Abstract: 1,205,792. Adhesive sheet material. BOSTIK Ltd. 29 Aug., 1967 [30 Aug., 1966], No. 39422/ 67. Heading B2E. A laminate comprises a protective carrier sheet having a release surface and an adhesive sheet material comprising (a) a first layer comprising an activatable adhesive composition and (b) a second layer comprising an anti-blocking composition which second layer is adhered to the first layer and is lightly adhered to the rear surface of the carrier sheet so that the carrier sheet can be stripped from the second layer of adhesive sheet material, the anti-blocking composition being such that when the carrier sheet is stripped from the second layer of adhesive sheet material the adhesive composition is activated and the adhesive sheet material pressed against a surface to bond it thereto the antiblocking compositions is at least partially displaced to permit the adhesive composition to adhesively engage the surface and bond thereto. The adhesive composition may be heat-activatable and anti-blocking composition may be a thermoplastic material having a melting point not less than 20F. lower than the activation temperature composition. In such cases the antibonding composition may be soluble in the molten adhesive composition. The second layer may have a thickness of 0.0001 inches or less. The adhesive composition may be formed of a thermoplastic polyester formed from glycol and an aromatic or saturated aliphatic dicarboxylic acid, such as polyesters formed from butylene glycol, ethylene glycol and polypropylene ether glycol and terephthalic or isophthalic acids or such aliphatic acids such as sebacic, azelaic and dimerised linoleic acid. A preferred polyester is a condensation product of terephthalic acid, isophthalic acid and sebacic acid with 1,4-butanediol. Other adhesives specified are polyamides, polyester amides, or acrylic and methacrylic resins and mixtures of polyethylene and other resins as well as those comprising natural rubber or butadiene-styrene copolymeric rubber which are particularly suitable when the antiblocking material comprises polyethylene. Suitable anti-blocking compositions include homopolymers of ethylene, copolymers of ethylene with vinyl acetate or alkyl acrylates such as ethyl acrylate, natural waxes, high molecular weight wax-like polyethylene glycols, paraffin wax and polyisopropylene or mixtures thereof. The laminate may be made by depositing the layer of anti-blocking composition onto the protective carrier sheet and subsequently depositing the layer of adhesive composition onto the layer of anti-blocking composition. The deposition may be effected by spraying, brushing or dipping using solutions in volatile organic solventsemulsions or as hot melts. The protective carrier sheet may be paper and may be coated with or impregnated with a silicone composition or with polytetrafluoroethylene.

Abstract: 1484302 Checking a catheter-manometer NETHERLANDS ORGANISATION FOR APPLIED SCIENTIFIC RESEARCH ON BEHALF OF PUBLIC HEALTH 20 Sept 1974 [21 Sept 1973] 41148/74 Heading G1N The correct functioning of a catheter-manometer can be checked by applying a sudden change in pressure to a part of the catheter tube outside the body 1. The catheter-manometer comprises a deformable tube 3 and a pressure transducer 5 for measuring blood pressure &c. The resulting pressure waves set up inside the tube are analyzed to see if the expected resonance frequency signal and the expected damping has occurred i.e. the tube is not blocked or leaking &c. A part of the tube at one end is surrounded by a pressure chamber 6 pressurized from a pressure reservoir 7 by way of a line containing a restriction 8. The chamber is also connected to an exhaust line 10 having a valve 11. The test is initiated by detecting at a detector 13 the top of the "R" wave in the E.C.G. signal. The signal 16 from a delay circuit 15 controlled by a heart frequency meter 14 causes the valve 11 to open suddenly and also opens a "time gate" or "window" 17 which in conjunction with a high pass filter 18 eliminates low frequency components, due to the blood pressure variations, of the signal 22 from the transducer 5 output signal. The resulting signal 20 is analyzed by a circuit 21 to give signals, at B and C, representing the reasonance frequency and the damping ratio of the catheter system.
