Title: Data processing apparatus
IPC: G01S7/295
Filed: 1977-04-05
Abstract: 1525048 Data processing systems I CATT 5 April 1977 [12 April 1976] 14908/76 Heading G4A A data processing system comprises a serial store formed of segments 15 between nodes 16, a fast data line 13 having access to each node, a plurality of by-pass lines 30 selectively bypassing respective portions of the store, each of which portions comprises one or more segments, switching means 33, 34 at the nodes controllable by commands to connect-in selected by-pass lines and link the correspondingly by-passed store portions into closed loops via respective feed-back lines 31, and a plurality of data processing units 36 each operable to perform a data processing operation involving information passing along the respective by-pass line and around the closed loop associated therewith. The commands may be sent on the fast data line 13 or on a slow data line 12 which comprises the linked segments 15; each segment 15 may comprise a shift register and may store one or more words of information, each word including address, data and instruction fields. The slow data line 12 may be divided into major loops, each comprising a plurality of the portions; each major loop may be set up with data and instructions and used to execute autonomously a sub-routine. A plurality of the major loops may be used for the parallel execution of sub-routines. In a preferred form, a major loop comprises four non-recirculating segments (A) followed by four recirculating segments (B) followed by four non-recirculating segments (A) and so on, the A data interacting with the B data in the data processing units 36 as it by-passes the recirculating B data as the data string passes along the major loop. Every four segments the recirculating/non-recirculating character of the A and B segments is interchanged, so that the B data then interacts with the A data as it by-passes the recirculating A data. This allows relatively complex data processing operations to be performed with simple data processing units 36, e.g. serial adders. The invention may be applied to data compression wherein common letter patterns in a stored text are searched for and replaced by single characters outside the normal alphabet. It may also be applied to process stored information derived from radar samples for collision avoidance purposes.

A spacing sleeve 20 and tie rod 21 axially space the rings 18, 19 by a predetermined distance. The rings 18, 19 abut the inner periphery of the clutch engaging pistons 9, 10 and have bores in which valve closure pins 24 are axially slidable. The valve loading springs 11, 12 bias the pins 24 to close the valves 25 and additionally bias the rings 18, 19 and clutch engaging pistons 9, 10 to a central clutch disengaged position. When clutch engaging pressure liquid is supplied to one of the clutch engaging pistons 9 (or 10) the resulting leftward (or rightward) clutch engaging movement of the piston 9 (or 10) is transmitted to the rings 18, 19 to open the valve 25 supplying the discs 13 (or 14) of the clutch which is being engaged. The leftward (or rightward) movement of the rings 18, 19 compresses the springs 12 (or 11) which return the rings 18, 19 and clutch engaging pistons 9, 10 to the central position when the clutch is disengaged.

IPC: H04B17/40
Filed: 1966-04-05
Abstract: 1,135,667. Pulse signalling. GENERAL ELECTRIC CO. Ltd. 5 July, 1967 [5 April, 1966], No. 15180/66. Heading H4L. Means are provided for testing repeater stations in a P.C.M. communication system by utilizing the low-frequency component of a P.C.M. -type of signal. A bi-polar type of signal is transmitted using pulse "trios", Fig. 1 (a), each trio consisting of three successive pulses of alternate polarity. Each trio will have a net positive or negative value, and by transmitting groups of "positive" trios alternately with groups of "negative" trios the low-frequency waveform (b) is transmitted as a test signal. Each repeater 7 includes a blocking oscillator 10 supplying a pulse output transformer 5 which tends to suppress the audio test signal as shown by waveform (d). Waveform (c) shows complete suppression. The rectifier 8 acts as a slicer for the signal (d) passing a range (e) which is displaced from zero by the forward volt drop of the diode 8. By this means the low-frequency test signal is recovered and returned via a filter 13 tuned to the frequency characteristic of the particular repeater, and line 4, to the terminal station.

Title: Improvements in or relating to modulated carrier wave systems
IPC: H04B1/68
Filed: 1938-05-21
Abstract: 506,306. Wireless transmitting and receiving systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 21, 1938, No. 15229. Convention date, March 8. Addition to 472,214. [Class 40 (v)] In a modulated carrier wave receiver or transmitter either sideband is reduced or suppressed, generally for the purpose of reducing interference caused by overlapping sidebands of adjacent carrier waves, by means of two coupled circuits fed simultaneously but with different phase from the same modulated carrier source. In the single sideband transmitter shown in Fig. 3, the carrier from source 1 is modulated at 4 and passed to the amplifiers 26, 27 whose inputs are connected in parallel. Valve 27 is resistance-capacity coupled to a further valve 8. Valve 26 is coupled by tuned circuit 18, 19, to valve 7, reaction being applied by coil 31. The output circuits of valves 7, 8 consist of the two coupled circuits 9, 10, 11 and 12, 13, 14, tuned to the carrier frequency, the coupling being provided by the mutual inductance between coils 11 and 12. Circuit 9 10, 11, due to the tuned circuit 18, 19 is excited with amplitude J and phase #1 as shown in Fig. 4, where fo is the carrier frequency, and circuit 12, 13, 14 is excited with approximately constant amplitude and phase #2. As a result in one circuit the upper sideband and in the other circuit the lower sideband is accentuated, as indicated by curves J and J2. The output from either circuit may be selected by switch 17 and passed to any suitable utilization means. Various degrees of sideband suppression may be obtained by varying the damping of tuned circuit 18, 19,-by adjustment of the reaction,- and by adjustment of the potentiometer 23. If a fixed additional phase-shift is introduced between the amplifiers 7 and 8 by means such as a capacity-resistance bridge, Fig. 6 (not shown), the characteristics of the coupled circuits are no longer symmetrical but a sharp cut-off is produced in one of the circuits at a frequency controlled by the initial phase displacement. This arrangement may be employed to provide ultra-selective band-pass circuits by providing two such circuits in cascade with appropriate cut-off frequencies. The single side-band suppression obtained with the symmetrical characteristic circuits may be improved by connecting a number of such circuits in cascade, one circuit of a group being fed via a valve from one tuned circuit of the preceding group, the other tuned circuits of each group being fed from the same source.

Title: Improvements in or relating to electric signalling systems
IPC: H04Q3/62
Filed: 1939-05-24
Abstract: 529,650. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. (Hertog, M. den, and Berden, A. C.). May 24, 1939, No. 15363. [Class 40 (iv)]  In a system employing break-impulsing over a direct current circuit, a further signalling condition is established during a break impulse by the connection of a rectifier across the impulsing contact. This may serve to prevent the setting up of certain calls, such as toll or rural calls, from a sub-station or from a P.B.X. As shown in connection with a substation, a rectifier RT is bridged across the line L by relay CR which energizes when the receiver is lifted. Authorized persons may disconnect the rectifier by means of a key K which is accessible only to such persons. Upon initiation of a call, the loop is extended by Lr to the impulse relay Is of a register-controller, and Pb, Le operate. The first digit is received in the customary manner, and if it indicates a toll call, Fd energizes and opens the original circuit of Lr, so that it is held over front contacts of itself and Is. At the first impulse of the second digit, therefore, Lr falls back and transfers the loop to Pb. This relay has its battery feed reversed compared with Is, consequently it remains held if the rectifier bridge at the sub-station is present and allows the operation of Es, which locks and brings about release, or alternatively sends a busy signal. If, on the other'hand, the rectifier bridge is not present, Pb falls back followed by Le. and the loop is extended to Is over a fresh circuit, so that the setting up of the connection continues in the normal manner. In the case of a P.B.X. at which dialled impulses are repeated, the repeating contact is shunted by the rectifier without the provision of a relay such as CR, and it may be arranged that the shunt is controlled by a relay which operates only on calls from certain subscribers. The signal may also be used to determine one of two metering tariffs on calls from rural exchanges.
