Abstract: 1,130,645. Transistor switching circuits. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 5 Oct., 1967 [26 Oct., 1966], No. 47971/66. Addition to 997,214. Heading H3T. In an SCR control circuit, producing trains of pulses, of the type described in Specification 997,214, the oscillator VT7, producing the pulse trains, is controlled via a timing circuit which has a predetermined minimum reset period irrespective of distortions of the A.C. input wave shape. Passage of the A.C. input at 1, 2 through zero momentarily switches off transistor VT1 to trigger monostable circuit VT2, VT3 to its unstable state in which transistor VT3 is cut off. Diode MR8 is then forward biased, and capacitor C5 discharges to reset the circuit, the reset time being only dependent on the time constant of the monostable circuit. At the end of the reset period transistor VT3 switches on, cutting off MR8 and capacitor C5 commences to charge exponentially until the charging current at the base of transistor VT4 equals the control current from terminals 3, 4, transistors VT4, VT5 then switch off. Transistor VT5 fires SCR to connect the collector supply to oscillator VT7 and VT4 produces the base drive, delayed by time constant C6, R20. VT7 now produces a burst of oscillation which lasts until the next reset period. In order to prevent spurious resetting, capacitor C2 is charged during the time VT3 is off, and its subsequent discharge is arranged to hold VT1 conducting for a predetermined time somewhat less than the duration of half a cycle of the A.C. input signal. During this time spurious zeroes in the input supply will not therefore switch VT 1  off.

A fluid pressure braking system comprises a generator associated with a vehicle road wheel and producing an interrupted or alternating current of a frequency related to the wheel speed, which current is passed through a filter and a rectifier to produce a direct current used to control a solenoid-operated valve in the braking system to render the brake inoperative if the current frequency falls below a predetermined figure. The generator comprises a ring of metal studs 12 carried on the brake drum rim 13 and passing through the field of a magnet having a battery energized winding 15 and a secondary winding 16 from which pulses pass to a filter. The output, which is proportional to 50 c.p.s. at about 5 m.p.h. vehicle speed, passes to a filter which passes only current at a frequency above say 150 c.p.s. to a rectifier, the D.C. output controlling a relay which when deenergized energizes the solenoid valve to release the brakes. The valve (Fig. 2) is arranged, when deenergized, to connect the inlet port 18 with the brake supply port 19 through a passage in a spring-biased valve spool 21. On energization of the solenoid 9b the plug 25 moves against its spring to close the spool passage and move the spool leftwards to part the spool valve 22 from its seat 23 and connect the port 19 with the exhaust port 20.

Filed: 1968-10-30
Abstract: 1,224,190. Digital transmission systems. INTERNATIONAL BUSINESS MACHINES CORP. 30 Oct., 1968 [30 Nov., 1967], No. 51442/68. Heading H4P. Digital data words in one alphabet are translated into another alphabet consisting of ndigit words such that the frequency spectrum of the new alphabet has zero points at selected frequencies. In one embodiment, Fig. 5 (not shown), in which k = 2 and n = 8, 6-bit signals are converted to 8-bit signals in which the number of 1-bits in even positions equals the number in odd positions. The 6-bit signal passes via stores and addresses a core store which delivers a 16- bit signal unique to the address and consisting of 4 groups of 4 bits. The groups are passed sequentially to an encoder which generates sequentially 4 groups of 4 bits, the bits of the first and second groups being interleaved in an output register from which the 8-bit word is transmitted serially. Other inputs to the system provide signals of different length to be translated, these inputs time-sharing the core store. In the case of an 11-bit input, for example, the 4 groups of 4 bits from the core store are interleaved in an output register such that the first bits of each group form the first bits to be transmitted, followed by all the second bits &c. In another embodiment, Fig. 6 (not shown), in which n = 15 and k = 3, from a 10-bit input signal is derived a signal consisting of 3 groups of 4 bits which is translated to 3 groups of 5 bits, the bits of the groups being interleaved to give a 15-bit character for transmission. The circuit is such that alternate characters are transmitted inverted. In Fig. 8 (not shown), where n = 12 and k = 4, from an 8-bit signal is derived 5 groups of 3 bits. Four of the groups are translated to a further 4 groups of 3 bits, the bits of the latter groups being interleaved for transmission. The transmitted signal is inverted if the fifth group indicates that the input signal has a value greater than 81. In Fig. 9 (not shown) where n = 7 and k = 2, three-level signals are generated. From an 8- bit signal a 14-bit signal is derived, pairs of bits in this signal being translated to +1, 0 or - 1 as appropriate to give a 7-bit 3-level output.

A buckle comprises a channel shaped main frame having a bottom 27 and side walls 29, a rotary latch 31 extending between said side walls and pivotally mounted thereto, and having a pair of detent portions 39, 35 extending outwardly from the pivot axis of the latch, a tongue 13 guidably insertable between the walls of said main frame, and between the bottom thereof and said rotary latch, said tongue having a latch opening 37, a pivotal catch member 59 mounted to said main frame whereby the leading edge of said tongue upon said insertion of the tongue rotates the latch in one direction to urge one of said detent portions 39 into engagement with the catch member and to urge the other detent portion 35 into tongue retaining engagement with the latch opening, the catch member restraining the latch against rotation in the reverse direction and release means 19 for disengaging the detent portion 39 from said latch member to permit reverse rotation of the latch and release  of said tongue from the frame. In the construction shown a coiled spring 43 holds the latch in such a position that the tongue upon entering between the walls of the main frame first engages the detent portion 39 to rotate the tongue, the rotation causing the detent portion 35 to enter the opening 37 and subsequently to enter an opening 61 in one arm of the catch member 59, the engagement of the detent portion 39 with the catch member arm preventing the reverse rotation of the latch. The release means 19 has an elongated base portion 69 with anuear 71 at each end which engage in notches at the rear of each side wall 29. The release means 19 also has tabs 73 extending from the base portion 69, the ears 71 and the tab 73 being compressed in sandwich fashion between the side walls of the main frame and a cover of the buckle. Also extending from the base portion 69 of the release means is a pair of resilient biassing fingers 65 and an arm carrying a push button. The fingers 65 each press downwardly on a detent portion 67 of the catch member 59 to restrain the catch member from rotation to release the detent portion 39. When release of the detent portion 39 is desired the push button is depressed and since it overlies a release arm 41 of the catch member 59 the catch member is rotated to release the detent portion 39 from the aperture 61. The tongue has a slot 21 for receiving a belt end portion and the side walls of the main frame carry a bar 53 in slots, the other belt end portion being looped round the bar and tension in the belt end portion causing the bar to slide so that an increased surface area of the belt end portion engages the bar to resist slipping of the belt portion.

Abstract: 1507219 Facsimile scanning ASSOCIATED PRESS 17 Dec 1975 [13 Jan 1975] 51629/75 Heading H4F In a receiver of a facsimile system, a laser beam is modulated by an acousto-optical modulator causing the beam to oscillate transverse to its scan direction so as to expose the entire width of the scan line and reproduce a continuous picture free of a line pattern. As described a frequency modulated, radio frequency carrier is amplitude modulated by the signal received from a transmitter and applied to acousto-optical modulator 44, the amplitude modulation causing direct modulation of the intensity of the laser beam and the frequency modulation causing the beam to be oscillated through a small angle (viz spot wobble on a C.R.T.). Mirror 42 scans the beam across the width of photosensitive paper 40 which is moved perpendicular to the scan direction by a roller 48 which is synchronized through logic circuit 54 with the drive to mirror 42. Also described is a transmitter having substantially the same components as the receiver with the exception (i) that photodetectors pick up light reflected from a document and generate an electric signal representative of the intensity variations across the document and (ii) the signal applied to the acousto-optical modulator is frequency but not amplitude modulated. Both the transmitter and receiver can be used in conjunction with known receivers and transmitters respectively. Preferred values are given for spot size, line width and carrier and modulation frequencies. It is stated that the "dither frequency" should be at least 10 times the bandwidth of the signal produced by the line scan alone.
