Title: Telecommunication systems
IPC: H04Q11/04
Filed: 1972-12-22
Abstract: 1380480 Automatic exchange systems STANDARD TELEPHONES & CABLES Ltd 22 Dec 1972 59386/72 Heading H4K  In a telecommunication exchange which is dependent for part of its operation on a parent exchange, communications within the exchange and to the parent exchange are effected in T.D.M. manner, subscriber lines are scanned repetitively for loop state signals, detected changes of state as compared with stored representations of the loop states during the preceding scan are used to compile digits in a register seized when an initial off-hook condition is detected, a wanted number or part thereof is compared with the directory numbers of subscribers connected to the dependent exchange and in the case of a local to local subscriber call a match is detected and the connection is set up independently of the parent exchange, the numbers being stored in the equipment/ directory number translator. As shown signals from subscriber lines and trunks of the parent exchange are received at the left hand side of the figure at receive terminating units RX TERM and are selectively gated via a highway H1 or H2 and corresponding demultiplexer DEMUY 1 or DEMUX 2 to subscriber lines or outgoing trunks. For a bidirectional connection two separate paths must be set up. The lines, trunks and highways may employ delta sigma, P.C.M. or pulse amplitude T.D.M. transmission. The exchange control includes an equipment number counter and addressed synchronously therewith connection stores CS1 and CS2, channel state and connection state code stores giving the calling state of the subscriber associated with a currently scanned equipment number and the current state reached in that connection, and a translator giving the directory number and class of service of that subscriber. This subscriber is the called subscriber in that the transmit terminating units TX TERM are enabled cyclically and the addresses read out of the connection stores CS1 and CS2 identify the called subscriber gates to be enabled. The line scanner(s) and dialled digit receivers are connected on the called subscriber side and operate only during their allotted time slots. The call state stores during ringing &c., override the normal control of the connection stores address decoders D1 and D2 to cause them to open alternative crosspoints to gate appropriate tones to the subscribers. In the case of call to or from the parent exchange the identity of the trunk used may be transmitted with the directory number of the wanted subscriber. A separate signalling channel between the exchanges is employed.
Patent GB-1459816-A (GB)
Title: Printer
IPC: B41J11/48
Filed: 1973-12-27
Abstract: 1459816 Control of printers SINGER CO 27 Dec 1973 [5 Jan 1973] 59815/73 Heading G4H A dot matrix printer 12 comprising one or more print carriages is capable of printing in both directions of motion of the carriage(s). It may incorporate means 60 for ensuring alignment of printed characters. As described, printer 12 comprises two 7-wire printheads 56, 58 for printing 9 Î 7 matrix characters on two out of three record media 36, 38, 46 simultaneously (e.g., a bill of sale and an audit trail in an electronic cash register). As the printer moves back and forth across the media, photosensors co-operate with coded apertures in a bar 60, Fig. 3A, to generate character strobe signals 71, 73 each of which triggers a one-shot 81, Figs. 5A (not shown). The trailing edge of the one-shot output initiates the printing of a new character on both media, the time for this being divided into 14 column times, Fig. 4. Each column time is divided into "A" and "B" halves for alternate printing on the two media. Data is input from a keyboard to a recirculating shift register (91) whence it is used to access a read-only memory (92) which produces printhead character control signals. The output from one shot 81 starts up and down counters (for left/right and right/left printer movement) which cause a multiplexer (86) to send alternate control signals to ROM (92). A comparator (88) compares the printer position 71 or 73 with the print positions of the characters at the output of register (91) in turn, and controls latch circuits (93) located between ROM (92) and the printheads (94), which are enabled alternately by sync. signals # A , # B , Fig. 4. The printer may include means for printing data upside-down on one of the media (e.g. for summing a bill).

Patent GB-749403-A (GB)
Abstract: 749,403. Electrostatic voltmeters. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Oct. 8, 1954 [Dec. 14, 1953], No. 34771/53. Class 37. An electrostatic voltmeter comprises a first electrode in the form of a rotatable vane, a second electrode co-operating therewith and a cylindrical screening electrode, interposed between the electrodes and connected to the first electrode, the cylindrical electrode being apertured so that it does not completely screen the first from the second electrode and the vane as a consequence rotates when a potential difference exists between it and the second electrodes, the aperture or apertures being so dimensioned as to provide a desired law of variation of deflection with applied potential difference. The vane 3 is mounted between jewelled bearings 5 and within the screening electrode 2 which is connected thereto. The vane is biased to a particular angular position by the hair-springs 6 and comprises a pair of part-cylindrical members 3a mounted on opposite ends of radially-extending arms 3b. By virtue of the apertures 7, the electric field due to the outer electrode 1 can act upon the vane 3 to cause it to rotate against the action of the springs 6. The apertures are in the shape of suitably tapered slots, Fig. 3 (not shown), to provide a desired scale shape for the instrument. A mirror 8 fixed to the shaft of the vane 3 and a window 9 are provided to enable the deflection to be indicated optically on a scale. Magnetic damping of the movement of the vane is provided by the damping vane 10 and permanent magnet 11. A further adjustable electrode 12, electrically connected to the outer electrode 1 may be provided to permit variation of the voltage range of the instrument by variation of the axial position of the electrode 12. It is stated that the optical indicating system may be replaced by a pointer or by a magnetic follow-up system providing a remote display. The invention is preferably applied to instruments mounted in an evacuated envelope but it is also applicable to instruments mounted in gas at atmospheric pressure, compressed gas, or oil. The hair-springs 6 may be replaced by a magnetic or gravity control. In an alternative arrangement the fixed electrode may be mounted interiorally of the screening electrode while the vane, comprising, for example, a pair of part-cylindrical members, carried on arms extending from a cross-member, traverses a path just outside the screen.

Title: A fixing rail for securing the pipes of an under-floor heating system
IPC: F24D3/14
Filed: 1979-12-05
Abstract: A fixing rail (12) is formed from a plastics material and is laid on a bearing floor (40) for fixing the heating pipes of an under-floor heating system. On its upper face it has recesses (24) at mutual intervals, for accommodating the heating pipes (38). In its lower region reinforcing wires (18) extend in the longitudinal direction.
