Title: Electric signalling system
IPC: H04M11/04
Filed: 1961-12-27
Abstract: 919,909. Automatic exchange systems. HESSELGREN, T. G. Dec. 27, 1961 [Jan. 2, 1961], No. 46237/61. Class 40 (4). In apparatus at a substation for establishing a call automatically in the event of a fire, burglary or other alarm condition, the impulse transmitter comprises a rotating disc I having conducting and non-conducting portions which generates a train of impulses at wipers a, b by means of the gapped periphery A0 . . . A9, while a selected one of wipers c ... k serves to shortcircuit wipers a, b during a variable part of the rotation to determine the number of impulses transmitted. The sequence of operations is controlled by a second disc IV also having conducting portions and co-operating wipers n ... s, the disc I being geared to make 24 rotations for one rotation of the disc IV. A wiper m carried by disc IV engages annular contacts of a fixed disc III. A selecting device SW comprises two sets of spiral springs arranged in insulating holders in adjacent planes with one set crossing the other set at right angles, so that interconnections can be made by the insertion of pins through holes at the crossing points, thus selectively connecting segments M1 . . . M10 of disc III to wipers b ... k. Assuming that contacts x, y are closed as the result of an alarm condition, motor M starts and drives discs I, IV, being maintained independently of x, y over contacts r, s for one revolution of IV. After a short time, contacts q, s are closed to operate relay T which switches the line L to the alarm signalling apparatus. While wiper m engages segment M11 (which is connected to contact b) the line is closed over contacts n, o to initiate a call. In due course wiper m engages segment M1 which as shown is connected at the switching device SW to wiper j, during one revolution of disc I, which generates 10 impulses at wipers a, b by means of its gapped periphery. Wiper j ceases to engage segment E when the first gap comes under wiper a, and re-engages it when A8 comes under a, thus nullifying the last two impulses generated. Six trains of impulses are sent while wiper m engages segments M1 . . . M6. If any segment is connected to wiper 6, all the impulses are suppressed and thus less than 6 digits may be catered for. As disc IV advances, wipers o, p engage a short segment OP and an audio signal is sent from oscillator OS to the selected substation to start a recorder, for example. Subsequently wipers p, n are closed and 4 trains of audio-frequency impulses are sent as segments M7 ... M10 are engaged in the same way as the selecting impulses. On the return of disc IV to normal motor M and relay T are disconnected. If contacts x, y are still closed the cycle will be repeated. To avoid this a highfrequency signal, e.g. 1700 c/s. modulated at 20 pulses per second, may be returned from the receiving substation, which after demodulation operates relay FR. If x, y are closed, transistor TR conducts after a delay and energizes relay U to effect disconnection. The conducting portions of discs I, III and IV may be formed by printed circuit technique.

Title: Method of Filling the Cells of a Battery with Electrolyte
Inventor: HULSE MICHAEL ANTHONY
IPC: H01M50/627
Filed: 1966-10-17
Abstract: 1,193,959. Filling batteries. JOSEPH LUCAS (INDUSTRIES) Ltd. 10 Oct., 1967 [17 Oct., 1966], No. 46279/66. Heading H1B. The cells of a battery are filled with electrolyte by introducing metered quantities of electrolyte into reservoirs 21 positioned above the cells 11 respectively, the reservoirs and the respective cells being interconnected, exhausting the air from the spaces 28 above the reservoirs so that the air from the cells bubbles through the electrolyte and the cells become exhausted and then increasing the pressure in the spaces and thereby forcing the electrolyte into the exhausted cells. A filling device for an annular alkaline battery 11 is shown which comprises a base-plate 12 which supports and locates the battery, a manifold block 15 which sits above the battery and an annular member 24. The manifold block has two concentric rings of reservoirs 21 which correspond to the two concentric rings of cells in the battery and which are connected to the filling holes of the cells by passages 22 which are of reduced diameter at their lower ends. The spaces 28 in the annular member 24 correspond to the reservoirs 21 and are interconnected by annular passages 29 which are connected to the common conduit 31. To fill the battery it is located on member 12 and the manifold 15 and gasket 14 are positioned on top of it. Electrolyte is poured into trough 19 so that it fills the recesses 21. Air pressure in the cells prevents electrolyte from draining through the narrow parts of the passages 22. Excess electrolyte is drained from trough 19 through radial drainage channel 20 and passage 20a (Fig. 3, not shown) and the bottom of the trough is wiped with a flat wiper to remove the last of the excess. Member 24 with gaskets 23 and 23a is replaced and air is evacuated from the cells through the electrolyte, spaces 28, passages 29 and conduit 31 until the cells are exhausted. Conduit 31 is then opened to the atmosphere and electrolyte is forced into the cells.

Title: Data processing control system
IPC: G06F15/177
Filed: 1973-10-04
Abstract: 1420878 Data processing systems INTERNATIONAL STANDARD ELECTRIC CORP 4 Oct 1973 [9 Oct 1972] 46408/73 Heading G4A [Also in Division H4] The system includes a number of identical processors and a number of memory units. The processors are so arranged that at any time only one, the executive processor, can execute certain predetermined programs, e.g. interrupt programs. Other programs of the system can be executed by more than one of the processors. The executive processor monitors the system and, according to the result of the monitoring, determines which of the processors, including itself, is to become the executive processor when next required, e.g. when a fault is detected. The embodiment described employs four processors CPU0-CPU3, of which CPUO and CPU1 are connected to a telephone toll switching network SA. Data relating, for example, to the release and setting up of call connections is processed by one or more of the processors. Each processor can execute a number of base programs which can be interrupted by interrupt programs (IP). The most important IP is a diagnostic program occurring when a fault is detected; this may interrupt any program (trap interrupt) to determine the fault in known manner. The second most important IP is initiated periodically (clock interrupt) to detect and store releasing call connections. The least important IP is initiated whenever the status of any processor changes (status interrupt). The status of a processor, which is calculated whenever an IP is initiated is represented by a value which depends upon whether or not the processor is on-line, is connected by a bus to the network SA, and is connected to memory controllers PMBOC, PMPIC, TMBOC and TMBIC. When a change in status value occurs the status interrupt program causes the present executive processor to calculate the status values of all of the processors and that processor having the highest status value is then chosen as the executive processor. Irrespective of whether the processor remains as or ceases to be executive the call processing load is immediately redistributed as necessary over all the on-line processors, according to one of the predetermined programs.

Abstract: 472,078. R÷ntgen - ray apparatus. POWERS, F. T. June 24, 1936, No. 17492. [Class 98 (i)] In radiographic apparatus comprising a vertical frame on which a cassette, an X-ray tube and an immobilizer for holding the patient, are vertically movable, movement of the cassette to suit the patient automatically moves the immobilizer and the X-ray tube while maintaining constant their relative vertical positions. As shown, the film cassette 10 is mounted on a table 11 vertically guided on frame members 2, 3 by rollers 13. The table also bears a shaft 14, Fig. 2, carrying pinions 15 engaging racks 18 on the frames 2, 3, so that rotation of a hand wheel 17 on the shaft 14 vertically adjusts the cassette, which is counterbalanced by a weight 22 connected to the cassette by a wire passing over a pulley 21. The immobilizer band 37, Fig. 1, is carried on arms 34 supported on a shaft 26 rotatable in end-plates 28, 29 guided on the frames by rollers 33 and bearing a shaft 25 carrying pinions 30, Fig. 2, engaging racks 24 carried by the cassette. The immobilizer thus moves vertically with the cassette, and is also movable relative to the cassette by rotation of the shaft 25 by the hand wheel 31. The immobilizer is connected to a counterweight 55 by a wire 52 passing over pulleys 53, 54, the weight 55 being connected by a wire 59 to the X-ray tube 56 movable on the frame member 1 ; this movement of the immobilizer produces an equal movement of the tube 56. The shaft 26 carrying the band 37 also carries a brake wheel 38 engaged by a brake band 39 releasable by pressure on a lever 41, and an arm 43 serves for rotating the shaft when the brake is released. The patient stands against the cassette, which is adjusted to the desired height, and the vertical position of the band 37 is adjusted until it coincides with the part to be radiographed ; such adjustment automatically adjusts the position of the tube 56. The shaft 26 is then rotated until the band 37 presses the patient against the cassette, when the shaft is clamped and the exposure suitable to the particular patient is read on a scale 50 carried on a plate 44 bearing a pointer 45 pressed by a spring 47 against a lever 49 carried on the shaft 26.

Abstract: 1,105,272. Testing potentiometric recorders; dynamometers. CENTRAL ELECTRICITY GENERATING BOARD. Feb. 24, 1966 [Nov. 25, 1964], No. 47925/64. Headings G1U and G1W. A portable test equipment for testing a multi input potentiometric recorder incorporates a voltage divider R1-R25 energized from a battery 102, which supplies a series of voltage outputs which are applied simultaneously to the inputs of the potentiometer under test in order to test the functioning of the recorder over a full working range. The range of voltage outputs from the divider is variable, by means of coarse and fine variable resistors B, C and range changing switch D. The testing device also incorporates a calibrating potentiometer arrangement, including reference and standardizing batteries 150, and 152, variable resistors Z1, Z2, meter Y and range changing switch X for supplying defined voltages at the terminals W1, W2. Arrangements are incorporated in the testing device for determining the contact dwell times of the electro-mechanical converters in the recorder. These are connected at K or J and energized from an A. C. socket 104, the dwell time on either side being indicated on the meter M. The emission of the valves used in the recorder may be determined by connecting them into the positions F, G or H as appropriate. The valve heaters are supplied from the socket 104 and the valve anodes from the battery 102. Current through the valve is determined on the meter M. A variable microvolt output for testing the servosystem of the recorder is derived from the potentiometer RV4 and the potential divider R34, R35. The constant voltage source in the recorder is tested by applying its output to the socket S, selecting the range by switch R and applying the voltage appearing at the output T to the terminals W1, W2, so that it may be measured by the calibrating potentiometer. A separate torque tester is provided in the equipment to test the effort required to move the balance and chart drive systems. Suitable connecting rods are held in the chuck of the tester and coupled to the system. The tester is gently rotated and the torque required to move the system is registered on a memory needle on the end of the tester.
