Title: Electrical signal receivers selectively responsive to different voltages
Inventor: OBERMAN ROELOF MAARTEN MARIE
IPC: H04L25/49
Filed: 1947-12-30
Abstract: 656,184. Electric signalling systems. STAATSBEDRIJF DER POSTERIJEN TELEGRAFIE EN TELEFONIE. Dec. 30, 1947, No. 34844. Convention date, Aug. 22, 1944. [Class 40 (i)] [Also in Group XXXIX] A receiver for responding selectively to a potential applied to a signalling wire comprises a chain of four valves BA ... BD with relays A ... D in their anode circuits, the grid bias of the valves being derived from a potentiometer including resistances which are switched in and out by relays B ... D to shift the bias of the valves earlier in the chain, with the result that different combinations of relays are operated as the signalling potential is varied in steps. As shown, the signalling potential is variable from a normal value of - 30 volts by steps of - 2 volts to - 60 volts, and the valves, which are pentodes, have a normal bias of - 32, - 34, - 38 and - 46 volts respectively. A signalling potential of - 32 volts operates A, whereas a potential of - 34 or - 36 volts operates B which immediately makes the bias of BA 4 volts more negative, so that A operates only in the latter case. In the same way, the operation of C by a potential of - 38 to - 44 volts alters the bias of both BA and BB to determine the potential more accurately. The relays A, B, C have opposing windings in series respectively with operating windings of B, C, D, thereby preventing momentary and possibly false operation of, say A, by a signalling voltage sufficient to operate B ; the possible operation of A being delayed until B has shifted the bias on BA, whereupon the opposing winding of A is short-circuited and A may operate if the signalling voltage and the new bias bear the correct relationship. Specification 655,369 is referred to.

Abstract: 1,159,996. Laminating process. W. R. GRACE & CO. 4 Aug., 1967 [5 Aug., 1966], No. 35257/66. Heading B5N. A process for the production of a laminate comprises extruding a 0À3 to 3 mils thick film 14 of an ethylene polymer at a melt temperature of 280-310‹ C. on to a cooled roller 15, and contacting this film with a film 1 of a vinyl chloride polymer in the nip between roller 15 and a further roller 10, the film 1 having a thickness of at least 0À5 mil and a temperature of less than 25‹ C. when it contacts the film 14, the film 14 on reaching the nip, having its surfaces adjacent and remote from the roller 15 at temperatures respectively below and above the crystalline melting point of the ethylene polymer. The laminate 16 is maintained in contact with the cooled roller 15 after passing through the nip and is thereby cooled to room temperature in not more than 1 sec., eg. ¢ sec. The roller 15 is cooled internally by water at 10-12‹ C. Roller 10 is cooled internally by water at 5-8‹ C. and externally by water drawn via a roll 11 from a bath 12. The film 1, drawn from a supply roll 2, is subjected to an oxidative treatment, e.g. corona discharge at 4, is coated with a primer at 6 and is dried at 8. The primer may be a melamine-formaldehyde resin or a polyalkylene imine, e.g. polyethylene imine. The vinyl chloride polymer may be p.v.c. containing 0-25% by weight of plasticizer or copolymers of vinyl chloride and any one of vinyl acetate, styrene, acrylonitrile, dialkyl fumarate or maleate, an alkyl acrylate or methacrylate, or vinylidene chloride. The ethylene polymer may be polyethylene, e.g. of density 0À91 to 0À94 and copolymers of ethylene with any one of the salts and esters of acrylic or methacrylic acids, e.g. alkylacrylates or methacrylates.

Title: Improvements in or relating to fuel injection pumps
IPC: F02M59/02
Filed: 1955-12-09
Abstract: 778,127. Starting direct injection engines. BOSCH GES., R. Dec. 9, 1955 [Dec. 11, 1954], No. 35343/55. Class 7 (3). [Also in Group XXVIII] In a fuel injection pump in which a pump member is adapted to be driven with a compound motion having both axially and rotary reciprocatory components one end section 3 forms an injection pump piston and the opposite end section 4 a fuel supply pump, the inlet and outlet of both the injection and supply pump being controlled by the rotary oscillatory motion of the piston. Fuel is drawn by the supply pump from an inlet 64 and is forced into a passage 41 and through an adjustable throttle 50 to the inlet of the fuel injection pump which forces fuel through a spring loaded valve 15 to the outlet connection 16. The end of the fuel injection pump cylinder is closed by a piston 7 loaded by a spring 10. Fuel also passes from the passage 41 through a throttle valve 42 loaded by a spring 43 to a chamber 22 and passes through a spring loaded ball valve 24 and a throttle passage 34 to an outlet 36. The piston 7 is subjected to pressure in the chamber 20. On starting the engine fuel supply pressure is sufficient only to lift the valve 24 against the force of its spring 28 hence the pressure in the chamber 20 is controlled by the spring 28. Injection pressure at starting is insufficient to overcome the pressure in the chamber 20 acting on the piston 7 together with the spring pressure and hence injection commences immediately the inlet is closed and continues until the spill port 61 communicates with the pasage 41. The pressure in the passage 41 may however be sufficiently high that injection takes place throughout the full stroke of the piston. As the engine speeds up the fuel supply pressure increases and this pressure acting on a sleeve 26. forces it to the right until grooves 33 communicate with the passage 36, the valve 24 is then relieved of spring pressure. In this condition the initial stroke of the injection plunger forces the piston 7 upwards until it contacts a stop 17 thereafter injection takes place until the spill port 61 is opened.

Abstract: In continuous mode, the device operates with ultrasonic pulses (11) and only operates additionally with microwave radiation pulses (12) when the device section (1) operating with ultrasound emits a signal. The device component (2) with microwave radiation is only switched on (4) with delay after detection of the signal which indicates an event which, per se already exists. Radiation pulses of the two device components (1 and 2) are then used for carrying out a coincidence detection (15), preferably with speed comparison, which only then decides on an alarm signal (151). <IMAGE>

Abstract: 1,218,664. Photographic processing. INTERNATIONAL POLAROID CORP. July 25, 1968 [July 25, 1967], No. 35630/ 68. Heading G2A. A pod 31 of photographic processing liquid is ruptured and its contents spread between a pair of image transfer sheets 40, 41 by pulling the sheets through the narrow gap between two spreader members 14, 15. The upper member 15 has a rearwardly extending guide portion 21, and the lower member 14 has a rearwardly extending guide portion formed of a guide platform 16 which has a relieved part 25 just before the gap, which helps to control the flow of the liquid. The part 25 is formed by making a U-shaped cut in the platform 16, and bending down the cut-out part to form a tongue 29. The members 14, 15 themselves are mounted on a pair of U-shaped springs, as at 11 see also Fig. 2 (not shown), so that they are resiliently biased towards each other. As the pod 31 is squeezed between members 14, 15, it is distended just prior to being ruptured, and this could force the members 14, 15 momentarily farther apart. Since the width of this gap is quite critical, this could upset the proper functioning of the device. The provision of the relieved portion allows the momentarily distended pod to occupy this space, and so prevents undesirable widening of the gap.
