Filed: 1974-10-02
Abstract: 1488824 Time division multiplex systems SOC ANON DE TELECOMMUNICATIONS 2 Oct 1974 [3 Oct 1973] 42682/74 Heading H4M In an intermediate station for a TDM system wherein at least one channel component is to be dropped and a new one inserted, while others are relayed unchanged, the different channel components being initially plesiochronous and synchronized to a single digit rate by positive pulse stuffing, the channels to be relayed are passed directly from the station demultiplexer to the station multiplexer without being resynchronized. Each channel component comprises information and stuffing digits and stuffing indication defining the status of the stuffable slots. The demultiplexer and multiplexer clocks in the station are synchronized in frequency and phase. The station incorporates a desynchronizer for each channel to be dropped and a synchronizer for each channel to be inserted which comprises at an output connected to the station multiplexer a mixer receiving information and stuffing digits, stuffing indications and a timing signal at the stuffed digit rate. The mixer output comprises during the first half of each time slot the information and stuffing signal and during the second half the stuffing indication. To insert a new signal into a spare channel in the multiplex frame the signal bits recovered at 24 of the synchronizer, Fig. 3 are fed into memories 29 in accordance with the bit frequency (which is applied at 23 to a recording counter 30 which controls the memories). Signals at the multiplexer bit frequency are supplied at 26 and pass to a reading counter 32. This counter controls gates 31 such that the data stored in the memories 29 is passed at an appropriate rate, synchronous with the multiplex frame, to line 27. A comparator 33 compares the recording and reading counter rates and in the event of discrepancy, a signal issues on line 34 to control the stuffing circuit 35 such that stuffing pulses are provided with are added to the data pulses. Furthermore, digits indicating the presence of stuffing pulses are combined with data and stuffing pulses as the second half of the transmitted pulses. The multiplexer (Fig. 4) is synchronized with the demultiplexer at the input to the station by signals applied at 37, 38 to a clock 39. The output from this passes to dividers 40, 41, 42. Divider 40 provides an output to control the read signal control circuit 47, which controls the gates 52-59 each receiving individual channels and operating to apply channel pulses to the stages 43 of a shift register, which is driven out to the output line at the multiplex frame rate determined by clock 39. The system is synchronized by a frame synchronization detector 46. Pulses to the reading counter 32, Fig. 3, are delivered by a reading registers control 48 operated from the various divider stages while those for enabling stuffing are delivered from a control 49.

Abstract: 935,693. Measuring instruments; voltage and current measurements. VERBUNDNETZ OST VEB. Dec. 18, 1959, No. 43062/59. Class 37. In a measuring apparatus for fault values of voltage and current in a supply line occurring, e.g. at short-circuit or transient overload, a supply line energizes current transformers 1, 11 in series, of which 11 is saturated and energizes relay 2 through variable resistance 22 to operate at a given threshold level of current whereby contacts 21 are changed over to energize bridge rectifier 3 from transformer 1 to develop a voltage representing fault current. Contacts 23 of relay 2 close an energization circuit for a variable delay relay 5 having shunt capacitance and variable series resistance, which after a predetermined time closes contacts 51-52 whereby capacitance 4 is charged from rectifier 3 and capacitance shunted relay 6 is energized over series resistance to operate after a predetermined time delay and close holding contacts 63 to energize an alarm signal. Contacts 61 then close to discharge capacitance 4 over time delay circuit 7 into ammeter 5 while contacts 62 open to allow a pointer arresting device 9 having a capacitance resistance delay circuit matched to delay line 7 to release the ammeter, which then reads proportionally to the fault current in the line. At the end of its preset time delay the arresting device releases and holds the pointer at maximum deflection, and after measurement a pushbutton de-energizes relay 6 and the alarm signal. Fig. 2 shows an associated fault voltage measuring circuit operative on fault current exceeding a predetermined value, wherein the voltage between faulty phase wires is selected by relays 2, 12 to energize transformer 13 feeding rectifier 14, which is connected over contact 54 of time delay relay 5 (Fig. 1) to charge capacitance 15, which on operation of changeover relay 6 (Fig. 1) discharges over delay line 17 into voltmeter 16 indicating the fault voltage; the pointer being retained in its maximum position by a drag spring bearing on a friction track from which it is releasable by a mechanical control.

Abstract: 1,035,240. Valves. WAGNER ELECTRIC CORPORATION. Nov. 8, 1963 [April 23, 1963], No. 44124/63. Heading F2V.  A dual valve for two separate brake systems 8, 13 has the two inlets 26, 26a supplied with fluid from separate reservoirs 4, 10 connected to a common pump 15. Upon manually operating a pedal 52 a force is applied to a piston 39 through a plate 47 and a metering spring 46 and the piston extension 42 is moved into abutment with a movable closure 37; concomitantly the resulting compressive force on a return spring 43 effects rightward motion of the housings 18, 18a against the compression force of return spring 43a and since these return springs are balanced the " follow-up " movement of the housings 18, 18a causes a movable closure 37a to abut a piston extension 42a. These valve movements close-off the outer chambers 24, 24a and hence outlets 27, 27a from atmosphere; further motion of the housings causes closures 37, 37a to disengage seats 29, 29a to connect the inlets 26, 26a with the outlets 27, 27a. The forces and reaction forces established by fluid pressure acting on the housing and the components in the inlet chambers 23, 23a and the outlet chambers 24, 24a are both equal and self-cancelling. When the reaction on manually applied forces are equal the extensions 42, 42a and closures 37, 37a are "lapped"; the reaction force acting via the spring 46 also provides " feel." In the event of failure of either valve or associated brake system the other valve and system are operated normally but the pedal requires an increased stroke. The two valves may be operated in sequence rather than simultaneously, one being operated mechanically and the other by the pressure fluid controlled thereby. Piston 39a is connected to a fixed member 56.
