Title: Improvements in or relating to electric protective systems
IPC: H02H3/30
Filed: 1925-08-19
Abstract: 262,842. Electrical Improvements, Ltd., and Grant, L. C. Aug. 19, 1925. Addition to 216,924. Cut-out arrangements.-Relates to a balanced protective system employing wireless or wiredwireless methods (instead of the usual field wires) and oscillating circuits one at each end of the section to be protected to supply high-frequency oscillations to the other, such frequencies being modulated, detuned, or controlled in respect of output by variations in the conditions of the protected circuit at the respective ends as described in the parent Specification. According to the invention, the control circuits F associated with the end of the section to be protected are connected up to the grid circuit of the transmitting valve B so as to vary the potential of the grid in accordance with variations in the conditions of the protected circuit. In the arrangement shown, current transformers F<1> in the ends of the section supply the primary 1 of an ironcore transformer F<2> the secondary of which is connected across the condenser E<5> in the grid circuit of the transmitting valve. The impedances of the windings of the transformer are chosen to suit the circuits to which they are connected. A second auxiliary valve C in parallel with the first serves as a stand-by and comes into action automatically in substitution for the first valve when the latter fails. This automatic substitution is achieved by the arrangement of resistances B<2>, C<2>, D<1> controlling the supply to the filaments and is described in Specification 258,718, [Class 40 (v), Wireless signalling &c.]. The control circuit F has the effect of modulating the normal oscillations of the transmitting circuit to a degree dependent upon the current in the power circuit without affecting the frequency. The oscillations at the other end are similarly modulated and, as the transmitting circuits are connected through a capacity coupling A<2> to the feeder, these modulated oscillations normally balance one another even with heavy straight. through currents and have no effect upon the detectors G which operate the relays G<2>. In the event of fault, however, the modulated oscillations operate the relays G<2> at each end and bring out the main circuit breakers G<3>. The relays G<2> may be tuned relays with holding coils as described in Specification 261,115.

Title: Improvements in or relating to the finishing and cutting of chamois leather

Filed: 1962-06-01
Abstract: <PICT:1007661/C6-C7/1> <PICT:1007661/C6-C7/2> <PICT:1007661/C6-C7/3> In finishing and cutting chamois leather into pieces having predetermined shapes and sizes, a sheet 4 of the seasoned, staked and ground leather or skin, Figs. 1 and 5, is laid on a relatively hard, flat cutting table 1, e.g. covered with synthetic plastic material 3, and a rigid frame or templet 5, having a rim 6, is placed on the leather and clamped, as by a pneumatic ram 18 having a thrust pad 19, which engages a member 20 projecting centrally from the frame.  The ram and the table are relatively movable horizontally, e.g. the ram may be moved in two horizontal directions, at right angles to each other, over the table. Alternatively, the frame may be clamped by cam-operated mechanism.  In another alternative construction, Fig. 2, the frame is made of magnetic metal and may include soft-iron armatures.  It is clamped by energizing electromagnets 7, located under the table; the provision of the member 20 then being unnecessary. An operator then cuts the leather with a knife, around the rim 6. Two frames may be placed, at the same time, on the leather sheet, and a bridging member may extend from one frame to the other to receive the thrust pad 19 of the ram.  Alternatively, the two frames may each be clamped by a ram. A constant is computed, on given costs of raw materials and labour, to represent the useful value which the operator should obtain from the leather sheet. Each frame is given an index value.  The operator then selects a frame, e.g. the largest possible, and subtracts its index value from the constant, to ascertain the index value of another frame for use on the remaining portion of the sheet.

Abstract: 983,142. Fluid bearings. HOVERCRAFT DEVELOPMENT Ltd. June 6, 1961 [June 16, 1960], No. 21263/60. Heading F2A. [Also in Division B7] Load-carrying apparatus for movably supporting a load comprises a bearing member 1 located in a concave housing 3 in a structure 2. Air is supplied to an annular port 4 in the housing 3 which forms a curtain 6 between the member 1 and the housing and maintains a cushion of air in the space 7. To improve the stability of the arrangement a further supply port 8 may be incorporated which divides the air cushion in the space 7. The bearing member may be spherical or cylindrical and in an alternative embodiment the housing may have an increased depth and a further annular supply port 10. Air thus supplied through ports 4 and 10 forms curtains 6 and 12 respectively on each side of the equatorial position of the member 1 which in conjunction with port 15 increases the number of air cushions. In the case of cylindrical bearing members, e.g. rollers, means are provided to maintain axial stability. In a further embodiment, means for spring mounting a member containing the bearing member is provided within a further member. The application of the load-carrying apparatus to air-cushioned road vehicles and track laying vehicles is described. Specifications 935,823, 935,824, 935,825 and 935,826 are referred to.

Title: Electrical circuits employing transistors
Inventor: WILLIAMS FREDERICK CALLAND
IPC: H03K5/07
Filed: 1953-02-10
Abstract: 750,988. Transistor circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 3, 1953 [Feb. 10, 1953], No. 21474/55. Divided out of 747,606. Class 40 (6). In an oscillator or pulse store, the emitter is . connected through a high impedance to the supply and over a diode to a reference voltage to limit its positive excursions, a low impedance collector connection being provided and an oscillatory or pulse forming network in the base lead so that the transistor conducts only during negative voltage swings of the pulse or the sine wave occurring on the base. As applied to a pulse store, Fig. 1, a delay line Zo with an open end is arranged in the base lead of the transistor T the base being returned to a small positive potential over inductor L. A negative pulse fed down the line is reflected without change of sign but is ineffective until a clock pulse, applied to diode D1, occurs whereupon the transistor T is switched on, the base falling to near - 10 volts. The duration of the resulting negative pulse at the base is equal to the pulse applied to D1 or the half period of inductor L, whichever is the shorter. When the circuit switches off, an overshoot occurs due to the inductor so that a wave symmetrical about +2 volts is propagated down the line. A pulse P is added to the store over diode D2 or erased by closure of a switch S. The delay line may be replaced by a mercury or magneto-strictive line. Pulse and sine wave generating and pulsedelaying circuits. When the cathode of diode D1, Fig. 2, is raised momentarily above the base potential, the transistor is switched on, and the emitter and base fall to nearly - 10 volts. Due to the. tuned circuit comprising the inductor L and stray capacities the base potential is carried positive, over-shooting the emitter and causing the transistor to switch off. The succeeding negative over-shoot causes the transistor to switch on and oscillation is thus maintained, the positive over-shoots being of large amplitude. If the coil is heavily damped, only one positive pulse results with a delay dependent on the tuned circuit. A positively biased diode may be connected to the base, Fig. 3 (not shown), to limit the positive overshoot and prolong its duration. The resistor R limits current flow,and capacitor C E  increases the time during which the transistor is on. In a modification, Fig. 4, when the transistor is switched on due to the base falling below the emitter it is arranged that the exponential fall of potentials due to Rc, Ce is approximately the same as the first quarter cycle of circuit LC. When the base rises in potential due to circuit LC the transistor switches off, the emitter rising as capacitor C E  discharges over resistor Rc until caught at earth by diode D1 conducting. At the beginning of the next negative half cycle, the transistor switches on again to maintain oscillation. Positive pulses are available at the collector. The circuit may be made self-running by returning the base to - 1 volts.
