Abstract: 1,201,487. Digital positioning apparatus. FEINMESS DRESDEN VEB. 4 Oct., 1967, No. 45128/67. Addition to 1,175,992. Heading G4H. [Also in Division G1] In the apparatus of the parent Specification, for stopping a machine tool carriage or turntable at positions determined by photoelectrically sensed marks, each mark carrier is provided with a coded indication of its identity which is sensed and compared with a command signal. Coincidence between the sensed and command signals initiates the slowing down of the carriage or turntable. The code may be in the form of cams sensed by feelers, electrically conductive or magnetic marks sensed by suitable pick-ups or reflective and non-reflective areas sensed by photo-diodes. The code is four or five digit binary. The marks on the mark carrier are sensed by three photo diodes so staggered that their output pulses after differentiation give pulses which occur a distance a/2 on either side of the rest position of the carriage or table, the distance a/2 being equal to the distance travelled by the carriage or table in stopping from its slowest speed.

Title: Subscriber line interface circuit
IPC: H04Q3/72
Filed: 1975-10-31
Abstract: 1481750 Automatic exchange systems INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1975 [23 Dec 1974] 45275/75 Heading H4K In a subscriber line circuit the wires of the line are connected respectively to earth and to a power supply terminal via individual feed circuits and each feed circuit includes a gyrator circuit and a capacitor, the combination exhibiting an inductive impedance which operates as a low pass circuit. The feed circuits 34, 35, Fig. 2, including the gyrator circuits, e.g. 34a, approximate to resistances for D.C. currents and to inductances each of value α=R3.R2C1 for A.C. currents. One of the circuits 35, Fig. 1, is connectable to one of two power supply terminals - 30 v., - 48 v., the voltage - 30 v. being applied if the handset is on hook, if ringing current is applied or if the line current is above an upper tolerance level, and the voltage - 48 v. being applied if the handset is off-hook and the line current is below a lower tolerance level. Where no varistor circuitry is included in the substation circuits components Z2, T3 and R5, Fig. 2, are omitted from each feed circuit and a changeover of supply voltage requires no modifications of these circuits. However if varistor circuitry is included it is necessary to maintain the line current constant on voltage changeover and transistor T3 is turned off by a signal B from the selection circuit when the voltage is switched to - 30 v. and the Zener diode Z2 acts to maintain the line current constant. Transistor T2 is switched on to inhibit the feed circuit during ringing, by using a signal RX derived from the selection circuit. A differential amplifier arrangement 44, 45 (Fig. 1) is used to eliminate echoes which may occur due to the signal S2 on line 18 being fed via the feed circuits 34, 35 to the line 26; the circuit 45 is therefore designed to simulate the feed circuits in this respect. Diode arrangements 36-38, 40-43 are used to limit signal amplitude levels. Components 19, 20 constitute the line terminating impedance.

Title: Electroacoustic transducer
IPC: G10K11/28
Filed: 1970-09-25
Abstract: 1320551 Ultrasonic vehicle detector GENERAL SIGNAL CORP 25 Sept 1970 [20 Oct 1969] 45725/70 Heading H4D A transducer means has associated therewith guide means for guiding the acoustic energy propagated by the transducer means through an elongate slot, thereby producing a line source such that the radiation pattern thereof is broader transverse to the slot than along. A system for detecting vehicles on a roadway, Fig. 2, comprises a transmit-receive transducer unit 15, suspended above the roadway, having beam pattern of elliptical cross-section. Time base generator 10 produces sync. pulses for transmitter pulse timer 22, producing 5 ms. pulses and range gate generator 11, producing a range gate inhibiting response to the transmitted pulse and any reflections from the road surface. Receiver pulse timer 23 passes pulses inside the range gate of duration more than 3 ms. and memory 24 stores the pulse until the end of the range gate. Detector 35 detects received pulses in two successive transmission periods and sets detector memory 19 which provides an output for an indicator and a release timer 20. Timer 20 is reset by every received pulse such that if no pulses are received in a predetermined time memory 19 is cleared. A similar system is described using only single pulse detection, but incorporating pulse length, amplitude and frequency discrimination (Fig. 1, not shown). Transducer 15, Fig. 5 comprises a ferro-magnetic base 40 supporting a magnet 38 and ferromagnetic polepieces 41, 46 which produce a magnetic field in annular gap 42. Diaphragm 45 carries a coil 44 in said gap which coil is connected to terminals 47. A signal applied to terminals 47 vibrates the diaphragm 45 and viceversa. The sound waves so produced are guided by removable members 52 and removable wedge 51, Fig. 8. The top edges of members 52 define with the walls of casing 48 a rectangular slot, which lies above the ridge 49 of wedge 51. In a device not falling within the scope of the invention, wedge 51 is replaced by bullet shaped insert (70, Fig. 11, not shown) and a plate having a rectangular slot fitted over the casing. This arrangement also produces the desired directional characteristic.
