Patent GB-1401436-A (GB)
Title: Pulse transmission systems
IPC: H04L5/14
Filed: 1971-10-14
Abstract: 1401436 Digital transmission; signalling by DC GENERAL ELECTRIC CO Ltd 20 Dec 1972 [14 Oct 1971] 47884/71 Heading H4P A transmission path carrying data in both directions during a similar period has pulses transmitted from a second terminal only during gaps between adjacent pulses received from a first terminal, each terminal having inhibiting means for substantially preventing pulses from a transmitting terminal from being detected by a receiver at that terminal. In the embodiment described the first terminal is a master and the second terminal a slave. Preferably timing pulses are issued by the master and controlled by a clock which pulses are regenerated at the slave, conveniently by a phase locked loop. The total delay of the transmission path may be arranged to be an integral number of half periods of bit frequency which ensures that incoming pulses from the slave fall into gaps from the master hence will not be suppressed by gating means at that terminal. If the path delay is not an exact multiple, incoming pulses may coincide with transmitted pulses hence may be suppressed; this may be overcome by making incoming pulses of greater duration than outgoing pulses. A further method is to insert a fixed delay of “ operating period or alternatively transmit from the slave terminal double pulses spaced ¢ period apart at least one of which will be unsuppressed.  Master terminal 2 receives binary input through pulse shaper 4 and transmits through line driver 5 binary or bipolar signals of period To determined by master clock 6 of duration shorter than To determined by pulse shaper 4. At slave 3, pulses are fed through gates 10 which allows pulses only to pass to amplifier 11 during periods t2 hence outgoing data through pulse shaper 7 and driver 8 is prevented from reaching amplifier 11. Output of 11 is applied to one input terminal of phase detector 12 the other input of which is supplied with a reference signal from oscillator 9 via 90 degree phase shift 13. Detector circuit 12 compares rising edge of reference waveform with centre of incoming pulses; if on either side of centre oscillator frequency adjustment is made. As a result pulses transmitted by a slave 3 are interleaved with incoming pulses from master 2. Incoming pulses are sampled by circuit 14 and samples above a threshold pass forward. At the master station incoming pulses pass through gate 15 controlled by clock 6 to prevent driver pulses reaching amplifier 16. The clock regeneration circuit may be similar to circuit 20. Incoming and outgoing pulses will be correctly interleaved if transmission delay is equal to an integral number of half periods of clock frequency which is ensured by a variable delay element 19. Where a fixed delay is employed, incoming pulses are taken from either before or after the delay element dependent on which point gives better degree of interleave.

Title: Concrete body
IPC: E01F9/506
Filed: 1977-11-17
Abstract: The concrete body consists at least partly of reflective concrete containing Portland cement, a hard filler, a pigment and crystal glass beads (E). The refractive index of the filler is at least approximately equal to that of the crystal glass beads. The particle size of the filler is smaller than that of the crystal glass beads. The crystal glass beads are approximately half exposed at the surface (D). Preferably the concrete body has a basic body (A) of normal grey concrete which is covered at least partly with a layer (B) of reflective concrete. In order to produce the concrete body, the dry components of the reflective concrete are mixed and water added. The resulting viscous mortar is either filled into a mould in an approximately 10 mm thick layer, the mould thoroughly vibrated and the concrete body pressed, or it is filled into a tubular hollow mould and moulded by centrifugal casting. After the concrete body is removed from the mould and allowed to harden, the surface of the crystal glass beads is exposed by etching with an acid. The concrete body can be used for reflective markings. <IMAGE>

Abstract: 1483518 Gain control circuits SONY CORP 7 Nov 1974 [13 Nov 1973 14 Dec 1973 15 Dec 1973] 48318/74 Heading H4R In a gain control circuit a common emitter amplifying transistor 36 has a variable impedance, formed by the drain source path of a resistive layer insulated gate field effect transistor, 10, in its emitter circuit to control the gain of the amplifying transistor 36. As described the emitter circuit of the transistor 36 includes a constant current source formed by transistor 40, which provides that the drain of FET 10 is held to the same D.C. potential as the source so that no D.C. current flows in the drain source path. If the two gate electrodes are held at a potential which is the control potential plus the signal potential on the respective source or drain electrode, the FET will present a source drain impedance bearing a linear relation to the control voltage. This is provided by resistor 17 which couples the gate electrodes 8 and 9 for D.C. control potential and capacitor 14 which has a low impedance for signal frequencies and a high impedance for the control voltage. In order to allow a higher frequency variation in the control voltage the coupling between the drain and the gate 9 may be via capacitor 14 and an emitter follower 50, Fig. 11, which has a constant current source provided by transistor 51 in its emitter circuit, the constant current source being coupled to the control voltage source by resistor 56 so that the collector potential of transistor 51 equals the control voltage and therefore the control appears on both terminals of capacitor 14, reducing the time constant of the feed of control voltage to gate 9, which would otherwise be C14 x R17. Capacitors 45, Fig. 9 and 57, Fig. 11, are provided to compensate for the drain source capacitance of the FET 11. In both Figs. 9 and 11, capacitor 34 decouples the gate 8 to the source potential. In an alternative arrangement for reducing the charging time constant of capacitor 14 to the control potential a switching transistor 60, Fig. 12 (not shown) is connected between the two gate electrodes 8 and 9 to be periodically rendered conductive, e.g. during the horizontal flyback period of a television video signal whose gain is being controlled.

A method of producing an insulating angle ring (for H.V. transformers) includes wrapping one or more insulating annular discs 27, 28 with a plurality of layers of insulating tape 32 (stuck together and/or to at least one annular disc) and then cutting the wrapping around the inner or the outer circumference 33 of the disc, the strips of tape so released being erected by withdrawing one disc 27 in the axial direction and being then supported by introducing insulating cylindrical sleeve(s). 35, Fig. 3, substantially perpendicular to the plane of the disc. A wrapping 34 may hold the tapes against the sleeve 35, and tape 36, 37 may be used to retain the outer edges, while extra annular discs 29, 30 may be included to maintain an equal overall flange thickness, allowing for the build-up of tape 32 at the inner circumference of discs 27, 28. Modifications include the provision of further annular discs and cylinders to reinforce the flanges and the tubular portions respectively (Figs. 4, 5, 6, 8, not shown), the discs and cylinders being secured by a loose outer wrapping of tape (51, Figs. 4, 5, not shown).
