Filed: 1967-07-05
Abstract: 1,181,725. Adder arrangements. ELLIOTT BROS. (LONDON) Ltd. 3 July, 1968 [5 July. 1967], No. 30913/67. Heading G4A. A fast parallel binary adder comprises a series of stages (one for each corresponding pair of bits to be added) arranged in multistage groups which operate at two time-separated levels of logic, the first level being concerned with generating from corresponding pairs of binary bits signals representing first and second half sums, stage carry generate, stage carry propagate, group carry generate and group carry propagate, the second level being concerned with deriving sum outputs from the output signals of the first level taking into account any carry. The first level of logic for the first two stages of an embodiment in which each group comprises two stages is shown in Fig. 3. In logic block 10 signals A 1  and B 1  representing the first corresponding pair of bits to be added are used to generate stage carry propagate P and stage carry generate G signals in true and inverted form together with first and second half sum signals S 01  and S 11 . In logic block 11, the second pair of bit signals A 2 , B 2  are used to generate the half sum signals S 02  and S 12  only. Group generate GG and group propagate GP signals in true and inverted form are generated in blocks 12 and 13 from the same input signals. The second level of logic for stages 1 and 2 is shown in blocks 15 and 16 of Fig. 5, where the output signals of blocks 10 and 11 together with a control signal Co in true and inverted form are used to generate sum outputs S 1  and S 2  for the first two stages. The control signal Co is binary 1 for addition and 0 for subtraction. The group carry generate and group carry propagate signals from blocks 12 and 13 are used in blocks 17 and 18 which correspond to the second level of logic for stages 3 and 4 (i.e. the next group in the series). Generalized equations for the sum outputs for any stage are derived in the Specification, the only signals carried forward from one group to later groups in the series being the group carry generate and group carry propagate signals. The gates of the logic blocks may be formed of metal oxide silicon transistors (MOST's) using integrated circuit techniques.

IPC: H04Q3/00
Filed: 1929-10-11
Abstract: 341,099. T e l e - phone systems. AUTOMATIC TELEPHONE MANUFACTURING CO., Ltd., Strowger Works, Liverpool, and JACKSON, H., 5, Maple Grove, St. Helens, Lancashire. Oct. 11, 1929, No. 30939. [Class 40 (iv).] Automatic telephone systems and apparatus.- A switch of Strowgertype having no separate release magnet, when released, is advanced by the rotary magnet to a twelfth rotary position in which the double dog is mechanically tripped so that the switch restores to normal under the action of the cup spring and gravity in the usual manner. The double dog 5 which is pivoted about an axis 6 and is usually operated by the release magnet armature engaging a part 7 is provided with an extension 11 which co-operates with a cam 12 on the switch shaft. In the twelfth rotary position, a web on the cam 12 strikes the extension 11 and trips the double dog, which is held in the tripped position by the engagement of a projection 18 in a slot in a spring associated with the vertical magnet armature until the latter is next operated. The double dog carries contact springs which are closed at the first operation of the vertical magnet and remain closed until the double dog is tripped. The cam 12 may also control the eleventh step springs. Circuit arrangements. In the group selector (Fig. 3) relay G energizes at the first vertical step over double dog springs DD and subsequently interacts with the rotary magnet RM when changeover relay C falls back until an idle line is found, when test and switching relay H pulls up in the usual manner. Upon release, when relay H falls back relay C energizes over both windings and closes a fresh circuit for relay G, which now interacts with the rotary magnet RM until the twelfth rotary position is reached, when the double dog is tripped and the switch is restored to normal. The test wire is grounded by relay C until the normal position is reached. If there is no idle line in the level, the wipers stop in the eleventh rotary position and cam springs S are operated in the usual manner. The momentary operation of these springs during the normal release movement is without effect. In the connector (Fig. 4), relay E, which is rendered sluggish by a short-circuited winding, energizes at the first impulse of the final train, closing a direct circuit for the rotary magnet RM and an alternative circuit for line relay A independent of busy relay G. If the wanted line is free, switching relay H energizes and the connection is completed in the usual manner, while if the line is busy, relay G energizes and a busy signal is sent back. Upon release, when relays A, B fall back, relay E re-energizes and interacts with the rotary magnet RM. Relay C energizes over both windings, opening the shortcircuited winding of relay E and grounding the test wire. The double dog is tripped when the twelfth rotary position is reached and the switch is restored to normal.

Title: Improvements in or relating to demodulation circuits for colour television receivers
IPC: H04N11/16
Filed: 1964-08-04
Abstract: 1,080,231. Colour television. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Aug. 4, 1964 [Aug. 8, 1963], No. 31110/64. Addition to 1,046,275. Heading H4F. The invention relates to a synchronous demodulation circuit for a colour carrier signal, Fig. 1, of the kind which is modulated along two axes by two colour signals I and Q, the Q signal axis remaining fixed in phase and the I signal axis being periodically reversed (e.g. at line frequency) as indicated at - I. Demodulation may be effected along the R-Y and B-Y axis, and in accordance with the invention (from one aspect) the demodulation oscillations for the synchronous demodulator are formed as indicated in Fig. 2 (for the R-Y signal only) by combining together in appropriate proportions two quadrature oscillations A and jB with the jB oscillation being subjected to periodic reversals to - jB in synchronism with the periodic reversal of the I signal of the carrier. Demodulation thus takes place alternately at the two angles R-Y and #R-Y so as always to derive R-Y despite the reversal of the I signal. Demodulation for B-Y is similarly effected alternately at the angles B-Y and #B-Y. A circuit for carrying out the invention is shown in Fig. 4 where a signal from the reference oscillator 1 is applied in one phase to one end of resistor networks 14, 15 and 16, 17 and is applied in a quadrature phase to the other ends by way of 90 degrees phase shifter 18, transformers 19, 24 and a diode reversing switch 22, 23 which is changed over at line frequency by switching signals 4, 5. By appropriate adjustment of resistors 14, 15 the R-Y, #R-Y signal of correct phase appears at point 25. Similarly by adjustment of resistors 16, 17 the B-Y, #B-Y signal appears at point 26. According to the invention from another aspect, the circuit for Fig. 4 may be employed to operate on the carrier signal whilst the reference oscillation is applied to the synchronous demodulator as normal without phase change. Resistor network 14, 15 and 16, 17 may be replaced by tapped transformers. Reference is made to the use of the invention in the X-Z demodulation system (see " Colour Television " by Carut and Townsend, page 241 et seq.). In this case the two demodulation axes occur in the same quadrant and the demodulation oscillations may be derived from two separate tapping points in one resistor network.
