Title: Improvements relating to hinges
Inventor: FERNBERG ERIC BIRGER
IPC: F16C11/04
Filed: 1960-02-12
Abstract: 945,547. Hinges and pivots; clips. F. T. PRODUCTS. Feb. 13, 1961 [Feb. 12, 1960], No. 5076/60. Headings E2B and E2F. In an assembly of two members articulated together with the aid of a U-shaped clip at least one of the members is formed with an aperture or a projection, a registering member, or a part thereof, is located in the aperture or around the projection, and the clip resiliently embraces the two members to hold them securely together so that relative pivotal movement can take place about the registering member. In Fig. 5 the members are flat shafts 38, 39 and the registering member 42 is integral with the shaft 38, but alternatively both shafts may be formed with an aperture 41 to receive a separate cylindrical or spherical registering member or both shafts may have raised portions 42 engaging an apertured registering member. The clip 30 has bent-up circular lugs 34, 35 to locate it in position. In Fig. 10 a shaft 68 is seated in a yoke at the end of a shaft 67 and is articulated by means of a cylindrical registering member 69 and washers 70, 71 which may be integral with the member 69 are provided between the shaft 68 and the limbs of the yoke. In Fig. 12 a dimple 83 formed in a member 81 engages an aperture 79 in a plate 76 and inwardly directed prongs are provided in the shorter limb 86 of the clip 78 to prevent its withdrawal. In Fig. 15 the registering member has a flat body 93 and a split cylindrical portion 98 with one end closed.
Patent GB-720739-A (GB)
Title: Improvements in or relating to circuits for separating two pulsatory signals
IPC: H04N5/10
Filed: 1953-02-25
Abstract: 720,739. Pulse discriminating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 25, 1953 [Feb. 29, 1952], No. 5264/53. Class 40 (6). In a circuit for separating signals of different pulse recurrence frequency, such as frame and line pulses, the composite signal is fed to the grid of a valve and a negative feedback circuit is effective only at the lower pulse recurrence frequency. The video signal of a television receiver is fed to the grid of valve 1 where the picture component is removed by grid current biasing the valve beyond cut-off between pulses. During the line pulses, the cathode and screen grid are held effectively at earth potential so that amplified line pulses are fed out from the anode. During the frame pulses, the capacitors 5, 7 exhibit reactances of at least the same order as the corresponding resistors 4, 6 so that heavy negative feed-back is effective. Pulses occurring at the frame frequency are fed out from the screen grid.

Filed: 1960-02-16
Abstract: 904,154. Testing thermionic tubes. DAYSTROM Inc. Feb. 16, 1960, No. 5408/60. Class 37. In apparatus for measuring the leakage resistance between a selected electrode 20 of a valve 17 and the remaining electrodes; switch means connect the selected electrode to one terminal 24 of a D.C. voltage source 10, and connect all other electrodes to the other terminal 25 by way of a D.C. measuring instrument 28. The D.C. voltage source and a subsidiary filament voltage are provided by secondary windings of transformer 10. A double throw switch 27 enables the measuring instrument 28 to be connected either directly across terminals 24, 25 for calibration purposes, or in operative position for measuring leakage resistance. The required electrode connections are effected by a selector switch, shown diagrammatically as the bars 37, 38, 39, 40, which are movable jointly from left to right. The apparatus may be incorporated in a mutual conductance tester.
Patent GB-1518643-A (GB)
Title: Stepped pulse generator circuit
IPC: H03K5/156
Filed: 1977-02-09
Abstract: 1518643 Stepped pulse generator LICENTIA PATENT VERWALTUNGS GmbH 9 Feb 1977 [12 Feb 1976] 05427/77 Heading H3T A pulse having a step, or pedestal, on both rising and falling edges is produced by connecting a falling ramp voltage at 2 to the commoned base inputs of two differential transistor amplifiers T 15, T16 and T17, T18 which have a common output connection and load R6. Different potentials are connected to the other inputs from different taps on a divider R9, R 11, R12. One output conducts from the start of the ramp, the second starts to conduct part of the way along the ramp, then the first ceases to conduct and finally all are off. The currents supplied to the differential amplifiers are equalised by the use of a controlling current mirror T 10, T 12, T13; and this ensures the mid point of the pulse is double the height of the two pedestals, themselves of the same height, either side of it. The pulse commences when a negative input is applied at 1 to turn off T6, and hence T3, T4, T5 permitting C to discharge, and T10 to conduct to supply current to the two amplifiers.

Title: Improvements in and relating to electric amplifying tubes
IPC: H03F1/08
Filed: 1935-04-11
Abstract: 454,760. Thermionic valves. VEREINIGTE GLUHLAMPEN UND ELECTRICITATS AKT.-GES., Ujpest, near Budapest. April 11, 1935, No. 5451/36. Convention date, April 11, 1934. Divided out of 454,606. [Class 39 (i)] An amplifying tube has four grid electrodes, the first grid 5, counting from the cathode 2, being connected metallically to the fourth grid 8 and the second and third grids 6, 7 being connected metallically to each other. The connections are made within the bulb or cap of the tube. In a modification, the fourth grid is connected, within the bulb or cap, to the cathode 2. The tube shown is used in the circuit claimed in Specification 454,606, grids 6, 7 being connected to a constant positive potential and grids 5, 8 acting as input grids. Higher sensitivity is obtained at low anode voltages. For high-frequency amplification, screens may be applied to either of the second or third grids and also to the fourth grid if this is connected to the cathode ; or the screens may be insulated from the grids and earthed or connected to the cathode. To reduce current to the grids 6, 7 the wires forming the grids may be arranged to cover each other in planes perpendicular to the cathode.

Title: Improvements in or relating to bathythermograph and sea sampler
IPC: G01K1/02
Filed: 1946-02-22
Abstract: 627,490. Sampling liquids. SUBMARINE SIGNAL CO. Feb. 22, 1946, No. 5550. Convention date, April 18, 1941. [Class 106(v)] [Also in Groups XIX and XX] A number of detachable tubular chambers 44 for capturing samples of sea water as described in U.S.A. Specification 2,314,372 are a rranged around the lower part of the cylindrical casing 1 of an instrument for recording the temperature of the sea as a function of the depth (see Groups XIX and XX). The valves 52, 53 at the upper and lower ends of these chambers are connected by links 56 and urged by springs 61 to the closed positions. Latches 68, however, hold the valves in the open position until notches 64 in a block 3, which slides in the casing 1 in accordance with depth as a result of the action of hydrostatic pressure on the sealed bellows 6, move opposite projections 67 on the latches. The distance of the projection 67 from the latch pivot determines the depth at which closure shall take place. The slight shock caused by the closure of the valves causes the stylus to make a mark on the temperature depth record. U.S.A. Specification 2,297,725 also is referred to.

Title: Improvements in or relating to methods for automatically charging iron-nickel accumulators
IPC: H01M10/44
Filed: 1925-03-03
Abstract: 230,816. Naamlooze Vennootschap Machinerieen-en Apparaten Fabrieken. March 13, 1924, [Convention date]. Void [Published under Sect. 91 of the Act]. Systems of charging batteries; lighting systems.-Iron-nickel accumulators are charged intermittently, with periods of rest between the periods of charge. Such a period of charging prevents during each charge the final rise of voltage occuring sooner than it did on the previous charge, and the consequent diminution of the effective capacity of the accumulator, which can only be restored to its normal state by excessive overcharging. The connection and disconnection of the accumulator from the source of supply is effected automatically, and the battery may be divided into two parts so that one part can be resting while the other is on charge, and thus the full output of the charging generator can be utilized. The method is applicable to the charging of accumulators in train illuminating systems.
