Title: Telephone tone ringer
Inventor: ROHNER PAUL
IPC: H04M19/04
Filed: 1966-08-19
Abstract: 1,097,047. Sub-station tone ringer; transistor pulse circuits. STANDARD TELEPHONES & CABLES Ltd. Aug. 19, 1966, No. 37189/66. Headings H3T and H4K. In a telephone sub-set tone ringer a transistor circuit supplies rectangular pulses at the low frequency of the ringing current to a little damped electro-acoustic receiver, preferably the rocking armature type, the harmonics of the pulses causing the receiver to resonate and produce a high-frequency tone output. In the circuit shown in Fig. 1, capacitor C1 charges alternately positive and negative with the 400 c.p.s. ringing current. The charging current in a positive half cycle induces a voltage in windings W1 and W2 of the anti-side tone coil of the subset to hold off transistor Tr, which voltage reverses as capacitor C1 begins to discharge and charge oppositely and is sufficient in the negative half cycle to turn-on the transistor, the collector current rapidly increasing due to the positive feedback induced in windings W1 and W2. However, negative feedback from the emitter resistor soon decreases the collector current and with the ensuing negative feedback in windings W1 and W2 and with the falling input voltage as the peak of the negative half cycle is reached the transistor is rapidly turned off. The resulting pulse of collector current passing through the receiver Rx2 causes it to resonate, the sound output being enhanced by a tuned horn and its level decided by resistors R1 to R3. Capacitor C2 and resistor R5 provide an optional damping stage to reduce the possibility of continuous oscillation of the transistor and also block high-frequency currents from passing to line.

Title: Hydraulic driving, braking and free wheeling mechanism for vehicles
IPC: B60K17/10
Filed: 1946-12-23
Abstract: 619,928. Hydraulic couplings and valveactuating. mechanism. CORNWELL, R. E., and McRAE, A. L. Dec. 23, 1946, No. 37670. [Classes 69 (ii) and 135] [Also in Groups XXVI, XXXI and XXXIV] Relates to a hydraulic transmission system for vehicles (see Group XXXI), consisting of four sets of rotary positive displacement motors and pumps, each set being hydraulically coupled, each motor and pump having a throttling partition and all sets being controlled from a single actuation device. Mounted on each road wheel W, W<1>, Fig. 1, is a hydraulic motor M consisting of a casing 10a, Fig. 7, and concentric rotor 11a mounted on the wheel spindle and having radially movable blades 16a, movement of which is controlled by a cam ring 18a with rollers 17a fitted to the blades riding on the cam ring. Controlling the inlet 46a and outlet 47a to the motor M is a throttling partition 13a which in the open position impinges on the rotor 11a. Each motor is hydraulically connected by pipes 58 and 59 to its respective pump, Fig. 4, which is similar in construction to the motors, each pump being driven from the vehicle prime mover. In the closed position of the partitions 13, 13a, there is no driving connection between each set of motor and pump. If the partition 13 on the pump only is closed, a braking effect on the motor is caused by hydraulic pressure in the pipe 59. The reversal of flow of liquid from the pumps to give a reverse drive to the vehicle is obtained by rotation through 90 degrees of a cylindrical plug 80, Fig. 4, having diametrical passages 81, 82 and at right-angles to these crossing, but not intersecting passages 83, 84. Each throttling partition 13, Fig. 5, is actuated reciprocally from its open to closed positions by an integral rack 53 engaging a worm 55 connected by a flexible shaft 56 to a pinion 67 carried in a compartment 64 of an actuation device A, Fig. 2. In the compartment 64 is rotatably mounted an internally toothed ring 65 having a control lever 71. Since the gear ring 65 meshes with the pinions 67, identical movements are caused on each partition 13 by movement of the lever 71. A similar set of controls for the motors is provided within a compartment 64a in the actuation device A being actuated by a lever 71a. Spring-loaded pistons 100, Fig. 4, and safety plugs 101 are provided in the fluid system to prevent excessive hydraulic pressures.

Abstract: 363,818. Fire-extinguishing sprinklers. MATHER & PLATT, Ltd., Park Works, Manchester. - (General Fire Extinguisher Co. ; Providence, Rhode Island, U.S.A.) Dec. 13, 1930, No. 37680. [Class 47 (ii).] In a sprinkler system of the kind in which the distributing pipes 10, 12, filled with gas under pressure, are connected to a tank 16 charged with a liquid under the gas pressure in the distributing pipes, a restricted con. nection between the pipes and the gas space of the tank, which serves normally to equalize the pressure therein, is closed by a float valve when a, sprinkler head opens and liquid commences to flow from the tank. As shown, a coupling unit 18 has a passageway 26 connecting the pipe 10 with the discharge pipe 30 of the tank. This passageway is connected by an opening 32 with a chamber 34 in which a float 46 is arranged. The chamber is connected by a restricted vent 44 and pipe 42 to the gas space in the tank. When liquid begins to flow from the tank, it enters the chamber 34 and tilts the float about a flexible coupling member 56. The float then engages the stem of a. valve 58 that closes the vent 44. At the same time, the stem 48 of the float moves a wedge member 62 to close contacts (not shown) in an alarm circuit to give a notification that the system has come into operation.

Title: Superconductive current measuring circuits
IPC: H03M1/12
Filed: 1975-09-16
Abstract: 1475847 Superconductive analogue-to-digital conversion INTERNATIONAL BUSINESS MACHINES CORP 16 Sept 1975 [31 Dec 1974] 37920/75 Headings H3X and H3H A Josephson superconducting tunnelling device 25 shunted by an inductive superconducting path 26 provides a sample and hold circuit for measurement of a varying unidirectional current Ia(t) from a source 40. In Fig. 1 the Josephson device is switched periodically by current pulses Ic in a control conductor 30, 31 from its resistive to its zero voltage state, the instantaneous current I L (t) in the inductive path at the time of switching being circulated in the closed path provided by the zero state Josephson device until such time that the device goes resistive at the end of a control pulse. The circulating pulse I L (t) remains at its initial value for the duration of the sampling period and may be applied to an analogue to digital converter 15. In an alternative arrangement, Fig. 4, the Josephson device is normally superconducting, and is set by design parameters or a control conductor current to switch to the resistive state whenever its gate current I G (t) exceeds a given threshold I MAX . With a source current Ia(t) increasing from zero, the Josephson device goes resistive when the current threshold I MAX  is reached. The current Ia(t) = I MAX  is then diverted into the inductive path. The Josephson device then reverts to its zero voltage state and remains there until the source current reaches 2 I MAX . At this threshold the device again becomes resistive for a short period and injects a further flux quanta into the inductive path. In this way a positive flux quanta is injected into the inductive path as each successive threshold increment is reached, the quanta being recorded over a superconducting transformer T in a bidirectional counter. If the current Ia(t) decreases, the Josephson device goes through successive resistive and zero voltage states as each I MAX  decrement is reached, and transfers a negative quanta each time back to source 40, each transfer being denoted by a pulse of reversed polarity from the transformer. Measurement of a varying current can therefore be effected by forward and backward movement in the counter.

Abstract: 385,293. Photographic processes photo-mechanical printing- surfaces. TECHNICOLOR MOTION PICTURE CORPORATION, 110, Brookline Avenue, Boston, U.S.A.-(Assignees of Troland, L. T. ; 110, Brookline Avenue, Boston, U.S.A.) May 14, 1931, No. 14281. Convention date, May 23, 1930. Drawings to Specification. [Class 98 (ii).] Positive films, particularly for imbibition printing, adapted to give correct contrast gradients in the high, middle and low ranges of exposure light, are produced by treating a light-sensitive photographic film with one or more sensitizing agents to render it sensitive to a broader spectral range and also by dyeing it with three or more dyes selectively absorptive in separate spectral zones within the sensitized range. The absorptive zones are preferably distinct but may overlap. In an example, a gelatine silver-halide emulsion is sensitized to blue, blue-green, green and yellow with erythrosin and is rendered absorptive in the blue, blue-green to green, and yellow zones by additions of tartrazine, Rose Bengal, and acid magenta. A film coated with the emulsion is exposed through a negative to light having a spectral range corresponding to the aggregate spectral range of the composite dye. If desired, a filter or filters may be introduced to adjust the ratios of the light components for the different spectral zones. The exposed film is then converted into a relief image, e.g. as described in Specification 204,034, [Class 98 (ii), Photographic processes &c.], or the film is developed with a non-tanning developer, fixed, bleached, etched with hot water and further fixed and dried, giving a gelatine relief suitable for imbibition printing. Specifications 263,331 and 263,650, [both in Class 98 (ii), Photographic processes &c.], also are referred to.
