IPC: H04Q11/04
Filed: 1965-02-19
Abstract: 1,103,602. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. 18 Feb., 1966 [19 Feb., 1966], No. 7254/65. Addition to 1,040,833. Heading H4K. The system of the parent Specification which is concerned primarily with an inter-exchange telephone network and which employs an independent signalling system for the establishment of connections is extended to cover the transmission of digital data messages as well as speech messages. Such data transmission need not include all the exchanges or switching centres of the network. In one arrangement signals from a telephone switching unit and a data transmission unit pass through check generators to a channel modulator. In the former case the check elements accompany each signal, whereas in the latter case they are associated with a block of signals. Thus at the incoming end the signals are distributed in accordance with the service address to appropriate check units which determine at different times whether the signals are acceptable and pass them to buffer stores.

Abstract: 589,516. Distilling and gasifying carbonaceous materials. BABCOCK & WILCOX CO. March 23, 1945, No. 7375. Convention date, March 23, 1944. [Class 55 (i)] In the distillation of hydrocarbon and carbohydrate materials comprising coal, lignite, peat, sawdust, heavy oil, shale &c. a mass of the material mixed with hot solid heat transfer material is passed downwardly through a retort 10 in which it is first subjected to low temperature distillation, then to a higher temperature distillation followed by a final combustion of the carbon deposited on the heat transfer material which is withdrawn at 260- 520‹C. to supply heat to the low temperature zone, ash being first removed as by a steam blast in section 91 of the discharge pipe. In the apparatus shown a gasification of the material with superheated steam is effected below the high temperature distillation zone. Circumferential outlets 35, 36 leading to pipes 42a and valved discharge lines 43, 45, provide for separate withdrawal of the low temperature distillates and the gases from the lower zone at which a temperature of 927-1,250‹C. is reached. Air for the combustion zone is introduced by a fan through a pipe 30 into which steam is also admitted to cool the heat transfer materal; a supplementary steam inlet for the water gas reaction comprises a vertically adjustable spider 29. Combustible material such as suitably sized coke may be used as heat transfer material, but it preferably comprises pellets of ceramic refractory or corrosion resistant alloy. In starting up, the retort is filled with the pellets and feeding and elevating means for their circulation through the retort started. Fuel gas is admitted through the outlet ports 35, 36 and burnt, the combustion products escaping through a top outlet 81. The coal &c. crushed, e.g., to ¢in. mesh size, is then introduced from an overhead bin through a feeder co-ordinated with the discharge feeder 52 and when operating temperatures are reached the fuel gas supply is discontinued and outlet 81 closed. Some gases may, however, be withdrawn from a top outlet 82 in addition to either of the ports 35, 36.

Filed: 1974-02-20
Abstract: 1466691 Spinning yarns HEBERLEIN HISPANO SA 20 Feb 1974 [20 Feb 1973] 7772/74 Headings DID and D1F In a spinning machine, the number of thread breakages in individual stations is continuously surveyed and, according to whether such number exceeds or falls short of a predetermined limit value, so the speed of a (common) spinning spindle drive is reduced or increased. Thread breakages may be detected by a single travelling sensor, cooperating and/or moving with a patrolling automatic thread knotting device: alternatively the breakages may be assessed in terms of the time taken by the latter device for each working cycle thereof which time is a function of the number of stoppages to repair breakages. In the controlled machine represented by Fig. 1, a sensor 3 signals (by transmission conductor 4) the breakages to a counting device 5 which measures breakages occurring in a predetermined time. A resultant value together with a limit value delivered by a preselector device 6 is fed to a comparison device 7 whence a signal is delivered to an adjusting device 8 which regulates a stepping motor of a device 10 which drives the spindles through a belt 11. In a modified control apparatus, Fig. 2, a sensor 3a, fixed to an automatic knotting device and moving therewith cyclically along the spindle stations, transmits the number of thread breakages each time it passes a stationary interrogator 14. The sensor comprises an electromagnetic moving element 15 which surveys the travellers rotation (and cessation thereof representing a thread breakage) and passes impulse signals representing breakages to a counter 16 whence strengthened signals are transmitted to a coding matrix 17: this is connected to coils 18 which induce a reverse magnetic polarity in soft iron cores 19 to represent the actual amount in the counter in binary code and this is transmitted to the interrogator by means of reed contacts 20, one or more of which are closed to effect transmission of the information. A coil 21 is so excited after the measured value has been transmitted to interrogator 14 as to close a contact 22 on counter 16 to reset to zero in readiness for a new cycle. The measured number of breakages is transmitted to comparing device 7 through amplifiers 23 which deliver a control signal to a step motor 24 movement of which operates a potentiometer 25 to adjust the speed of motor 10. Motor 24 may be replaced by electromagnetic and/or hydraulic devices and potentiometer 25 by on-load switch(es) or electronic devices. Lamps 26, 27, indicate whether or not the control device is operating and the sense of any deviation from the predetermined limit value. The apparatus of Fig. 3 (not shown) based on the times of each working cycle of the knotting device employs, inter alia, a time transducer and a time signals comparison device the output signals of which correctively operate a step motor which adjusts the speed of the spindle driving motor.

The phases # 1  # 2  are 90 degrees out of phase with each other. In # 1  time C1 charges negatively if A is negative, and C2 charges negatively through T3. After # 1  time T3 is off and C2 discharges to earth (line 10) through T2 since C1 has a negative voltage. T4, T5, T6 operate similarly in # 2  time and after; the output voltage 16 on C4 being negative since C3 adopts the earth potential of C2 so that T5 is not turned on to discharge C4. A plurality of these circuits may be arranged, on a single integrated circuit chip, to form a shift register.
