Title: Improvements in or referring to terminal strips comprising a number of contact members which are insulated from each other
IPC: H01H63/06
Filed: 1953-12-02
Abstract: 741,269. Electric selectors and connectors. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 2, 1953 [Dec. 5, 1952], No. 33489/53. Class 40 (4). [Also in Group XXII] A connecting device comprises a metal supporting strip 1 with transverse holes 2 in which metal wires 3 projecting at either side of the strip are positioned by means of an insulating mass. In a selector as shown, the strip 1 has further holes 4 for the introduction of a resin such as polystyrene and the wires 1 are held against movement by a flattened portion 12. After the wires are assembled as shown at A, they are flattened, B, and finally cut to shape, C, when they have contacts 10 and terminals 9. In a modification, Fig. 4, the transverse holes may be enlarged at one end 13. The invention may be applied to distributing strips in an exchange or connecting strips in electromagnetic relays.

Title: Hydraulic mechanism
IPC: F15B11/024
Filed: 1961-09-20
Abstract: 912,003. Hydraulic apparatus. NEW YORK AIR BRAKE CO. Sept. 20, 1961 [Oct. 31, 1960], No. 33644/61. Class 69 (2). An hydraulic system for controlling a doubleacting differential area piston motor 11 which may be used for raising and lowering the bucket of a digger has means for maintaining the expanding side of the motor filled with liquid without unduly limiting the rate of movement of the motor when a control valve 12 controlling the supply to the motor is in a " float " position and liquid is expelled from the motor under the action of the load on the motor. The control valve 12 is of the fourposition type, such as is described in Specification 859,658, having " float " and " hold " positions, and is connected by conduits 15, 16, 17 and 18 to a pump 13, sump 14, the rod end of the motor and a valving device 19, respectively. The device is also connected by a conduit 25 to the piston end of the motor and by a one-way valve 36 and conduit 26 to the conduit 17. The device has a shuttle 27 which is urged into a first position, as shown, by a spring 32. When the control valve 12 is moved to the " raise " position, the conduit 15 from the pump is connected to conduit 18 and the pressure therein acts on the end face 33 of the shuttle which is moved against the spring 32 to a second position wherein it connects conduit 18 to conduit 25 to raise the piston, liquid from above the piston passing through conduits 17, 16 to the sump 14. If the control valve is then moved to the " hold " position, the conduits 17 and 18 are disconnected from conduits 15 and 16, the pressure in conduits 18 and 25 retaining the shuttle in its second position so that the motor is hydraulically locked in position. Movement of the control valve to the " float " position interconnects conduits 15, 16, 17 and 18 and the drop in pressure in conduit 18 permits the spring 32 to return the shuttle to its first position so that liquid expelled from beneath the piston under the action of the load on the motor can pass through conduit 25, one-way valve 36 and conduits 26, 17 to maintain the space above the piston full of liquid to prevent cavitation therein, excess fluid passing through conduit 16 to the sump. When the control valve is moved to the " lower " position, the conduit 15 from the pump is connected to conduit 17 and the pressure in the latter conduit acts on a plunger 34 to move the shuttle to its second position to connect the conduit 25 from the piston end of the motor to conduit 18 which is connected by the valve 12 to the conduit 16 and sump 14.

Title: Improvements in pilot deviation alarm circuits for transmission systems
Inventor: BARBER DONALD ROBERT
IPC: H04J1/14
Filed: 1965-08-06
Abstract: 1,056,640. Pilot level alarms; transistor switching circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 6, 1965, No. 33807/65. Headings H3T and H4R. Alarm circuit, for indicating when the level of a pilot signal in, e.g., a coaxial repeater system, deviates from normal, comprises a semi-conductor controlled rectifier interposed between an interstice pair of cables in the transmission system which rectifier is held high impedance under normal pilot level conditions but is caused to conduct when the pilot level deviates from normal. As described the pilot signal is rectified and applied to the input of the two transistors VT1 and VT2, Fig. 2, connected in cascade. Under normal pilot level conditions transistors VT1 and VT2 conduct to keep semi-conductor controlled rectifier SCR2 switched on, which keeps transistor VT3 operating as a blocking oscillator. The oscillator output is applied via transformer T1, Fig. 1, and diode D2 to supply a biasing potential to the trigger electrode of the silicon-controlled rectifier SCR1 to maintain it non-conducting. If the pilot level deviates in either direction from normal transistor VT2 will be shut off causing SCR2 to shut off so that the blocking oscillator ceases to operate. The capacitor C1 is no longer charged by the rectified blocking oscillator output, so that its charge leaks away through R1, causing SCR1 to fire and put a low impedance on the interstice pair to indicate an alarm condition. Since an overvoltage across the interstice pair could cause SCR1 to fire, a Zener diode is preferably connected in parallel with SCR1 to eliminate voltage surges on the line.

Title: Improved method of producing coloured photographic materials
IPC: G03C1/825
Filed: 1932-12-02
Abstract: 415,756. Colour photography ; photographic films &c. GASPAR, B., 38, Innsbruckerstrasse, Schoneberg, Berlin. Dec. 2, 1932, No. 34229. Convention date, Dec. 2, 1931. [Class 98 (ii).] In coloured photographic materials comprising one or more emulsion layers carried by a support and containing acid or substantive dyestuffs, diffusion of the dyestuff is avoided by the formation of a difficultly-soluble, non- diffusing salt of the dyestuff by double decomposition of the dyestuff with a salt of a colourless nitrogenous organic base. The non-diffusing salt may be produced within or above the layer or in the emulsion prior to its application to the support. It may be applied to the emulsion in fine suspension or in solution e.g. in alcohol, or may be applied, atomized or impressed upon a colloidal layer. The material may comprise a number of part layers poured one upon the other or different coloured particles. Antihalation layers may also be produced and applied to the front or rear of the emulsion support. In Examples, (1) Diamine Pure Blue FF solution is admixed with a solution of guanidine sulphate, and (2) Metanil yellow is admixed with the hydrochloric acid salt of 2 phenyl - 4 - amino - quinoline. Specifications 133,034, [Class 98 (ii)], and 372,620 are referred to. The Specification as open to inspection under Sect. 91 refers to the use of nitrogenous organic bases generally and includes a reference to alkaloids such as quinine or cinchonine ; and describes also the incorporation of such bases in gelatine-coated paper adapted to receive pinatype &c. impressions. An example refers to the hydrochloride of 2 phenyl-4-amino quinoline. This subject-matter does not appear in the Specification as accepted.

In the example the bale is tied simultaneously with four parallel loops of wire, rope or strapping which pass beneath the filling box 1, forwardly at 32 into grooves 15 in the floor of the pressing box 2, around a catch 16 and upwardly to a pulley block 22, the binding being threaded by hand before baling starts. Material fed into a shoot 7 is compressed in stages to form the bale by reciprocation of the plunger which has needle grooves 4b, a knife for severing material against a stationary knife 9 and an apron 8 for supporting material remaining in the sheet 7. When a bale is complete a hooked needle on a motordriven belt 29 passes through the groove 4b to form a loop 32, 33, Fig. 7, of the lower pass 32. The loop is now cut at Z and an eye 18 on the other end of the tie is pulled to the right by a carriage 21 and is twisted with the severed end 32 to complete the tie.
