Filed: 1973-06-12
Abstract: 1412520 Automatic exchange systems SIEMENS-ALBIS AG 12 June 1973 [27 June 1972] 27865/73 Heading H4K A signalling data receiver in a TDM system utilizing a superordinate frame for conveying signalling data relating to the speech channels of an exchange time frame, comprises a storage matrix having as many rows as there are bit positions in a signalling time slot and as many columns as there are signalling time slots in a superordinate frame, each storage location in the matrix being connected via an individual amplifier to a bit-recording device, e.g. an electromagnetic relay. Each 125 Ás time frame comprises 32 time slots of which the first is used for synchronization, the 16th for channel related signalling data and the remaining 30 for information data. The superordinate frame spans 16 exchange frames. Its first time slot is used for synchronization while its second time slot contains 4 bits of data for the first channel and 4 bits for the 17th channel, and so on. The serial bits of each signalling time slot are inserted into a shift register SR for parallel read-out into a column of bi-stables SE which is selected by a sequence circuit TV in dependence on the particular position the slot occupies in the signalling frame. Each bi-stable is connected via an individual transistor amplifier SA to a bit-recording relay SB whose on or off condition is interpreted as a " 1 " or " 0 " bit by a not shown control system. In the amplifier, divider R1, R2 and resistor RE serve as a load current limiter, the RC circuit reduces HF peaks of the output pulse waveform and the diodes D1, D2 and Zener diode Z serve to divert surge voltages. The amplifiers are mounted on a common circuit board. In the event of a fault in the system a blocking pulse is applied via terminal B to reset all the bi-stables.

Title: Device for transmitting motion applicable among other uses to actuating the brakes of automobiles and the like
IPC: B60T11/04
Filed: 1925-11-11
Abstract: 257,780. Andersson, G. K. K. Nov. 11, 1925. Force-transmitting mechanism; compensating for wear.-Mechanism more particularly applic. able for operating band brakes and comprising toothed gear members adapted to give a quick movement for bringing the band into engagement with the drum followed by a relatively slower tightening movement is combined with an adjusting device by which the extent of the movement during which the slack is taken up can be varied in relation to the tightening movement. Adjustment may thus be made for wear or other purpose. Rods 1, 1<1> connected, respectively to the operating pedal and the brake are connected respectively to a slide 15 working in a fixed guide 16 and to an arm on a toothed wheel 18 pivoted on the slide and engaging a rack 21 formed on the guide. The arrangement is such that during the initial movement to apply the brakes, the rod 1<1> moves more rapidly than the rod 1 by reason of the rolling movement of the wheel 18 on the neck 21, the movement of the rods becoming equal however when the pivots 19, 14, 13 are in alignment as shown. The toothed wheel may be composed of two segments of different radii adapted to co-operate alternately with each rack. The guide and rack 16 is secured to a casing 4 and to effect the adjustment a nut 7 has right- and left-handed screw-threaded engagement with a fixed rod 8 and a rod 6 forming part of a bar secured to the casing 4, which may thus be shifted to vary the initial position of the pivot 14 and thus to take up wear in the brake.

Abstract: 1,049,457. Travelling wave tubes. INTERNATIONAL STANDARD ELECTRIC CORPORATION. July 6, 1965 [July 7, 1964], No. 28533/65. Heading H1D. A travelling wave tube helix assembly comprises three equally angularly spaced dielectric support rods disposed within a tubular metallic envelope and engaging three longitudinal grooves formed on the inner periphery of the envelope, and a resilient helix structure which applies pressure to secure the rods in the grooves. A signal attenuating coating, e.g. carbon, is formed on the rods, the coating being divided into two isolated longitudinal portions, one portion being in contact with the helix the other in contact with the metallic envelope by forming two diametrically opposed flats along opposite sides of the rods. In a method of assembly, the helix is wound about a shaft by rotating one end of the helix, the other end being fixed, thus reducing the diameter of the helix, and the assembly is inserted within the envelope with the rods; upon release of the helix it expands and forces the rods into engagement with the grooves.

Abstract: 739,029. Dispensing liquids; delivering measured quantities of powder. HARMON, F. Oct. 19, 1953, No. 28765/53. Classes 106 (5) and 116. Apparatus for dispensing beverages by introducing a charge of powdered beverage base into a liquid and having one or more containers for storage of the beverage base is characterized by means for tumbling the contents of the container or containers combined with means for dispensing a charge of beverage base from a container. The charges of beverage bases are contained in a series of containers 30 removably mounted in a yoke 31 mounted in bearings and rotated by a motor 33. Beneath the containers is a compartmented mixing chamber 38 with a top opening and outlet' spouts 39a. A hot water storage chamber 40 has a control valve 41 having delivery outlet 42 and nozzle 43 for each compartment. The motor is operated to rotate the containers 30 when a coin is placed in the machine and clockcontrolled mechanism may also operate the motor to tumble the contents periodically. The containers have each a valve 46 fitted on the yoke 31, the valve having a butterfly 45 which is opened by a solenoid operated member 45 which contacts a member 49 on the axis of the butterfly. A solenoid magnet is energized when a person presses a button to select the required drink and so moves the required member 45 into position to engage and rotate the member 49 and open the valve. Simultaneously the hot water and a cup are dispensed. To provide a weak or strong beverage a vane 47 is pivotally mounted on a shaft in the valve. The shaft carries two cranks with pins engaging in slots in two spaced levers pivotally mounted, the lower end of one of which may be arranged to be engaged by the member 45 as it is moved to engage the member 49 by pressing a strong or weak liquid button. This energizes one of two solenoids to move one of two levers whereby the lever 45 is made to contact one or other spaced lever, to rotate the vane to the more open or closed position. If neither button is pressed the vane is not moved. To disable the apparatus should the supply of beverage base run out a weighing pan 71 is also attached to the container 30 so that some of the base is retained on the pan during the tumbling. If there is sufficient in the container contacts 76 to 78 remain open, if not they close and a warning lamp lights up. In an alternative form for use for dispensing liquid of only one strength the valves are hinged to the containers and butterfly valves with four leaves are used. The follower 49 has four projections and the member 45 is a corresponding shape. The member 45 is moved radially by the solenoid into engagement instead of axially. The valve is turned through 90 degrees instead of 120 degrees and the supply for next delivery is retained in the valve.
