Abstract: 1366850 Fluidic elements HITACHI Ltd 29 July 1971 57398/73 Divided out of 1361207 Heading G4P A fluidic element 14 issuing an output alternately from two output ports 2, 2<SP>1</SP> is provided with an amplifier in the form of a monostable element 15<SP>11</SP> which is provided with a forced reverse control nozzle 43<SP>1</SP>. The monostable element 15<SP>11</SP> is such that its output issues from port 42 except while there is a control flow through a port 43. To speed up the device and allow switching at a higher frequency the nozzle 43<SP>1</SP> is arranged in opposition to port 43 and produces a flow to assist restoration of the output flow to port 42 when the control flow through 43 ceases. Port 43 is coupled to one output port 2 of the element 14 while nozzle 43<SP>1</SP> is coupled to the other. The nozzle 431 may provide a fluid resistance or an additional fluid resistor 13 may be included and this may be adjustable to match the element 14 to the element 15<SP>11</SP>. In Fig. 8 the amplifier is shown connected to a bi-stable counter element of the main Specification 1,361,207. It may equally be applied to any other two state output device such as a feedback type bi-stable (Fig. 11, not shown); a one-shot multivibrator (Fig. 12, not shown); a fluid AND-gate (Fig. 14, not shown); a shift register (Fig. 16, not shown).

Title: Time division multiplexer-demultiplexer for digital transmission at gigahertz rates
IPC: H04L5/22
Filed: 1972-12-20
Abstract: 1414467 Time division multiplex; transistor gating circuits SPERRY RAND CORP 20 Dec 1972 [22 Dec 1971] 58733/72 Headings H3T H4L and H4P In a time-division multiplex arrangement for microsecond binary digital signals the transmitter comprises a number of gates 14, 15 &c., Fig. 1, each with a signal input 17, 22 &c., a gating input 16, 21 &c. and an output 20, 23 &c. The gating inputs 16, 21, &c. are coupled to tapping points on a first delay line 24, a first end of which is fed from a nanosecond pulse generator 50, while the outputs 20, 23, &c. are connected to tapping points on a second delay line 26. The receiver comprises a number of corresponding gates 33, 34, &e. each with two inputs and an output; the one set of inputs 35, 40 &c. is connected to tapping points on a third delay line 44, one end of which is coupled by way of a first transmission line 30 to the second end of the first delay line 24. The other set of inputs 36, 41 &c. is coupled to tapping points on a fourth delay line 46 one end of which is coupled via a second transmission line 31 to one end of the second delay line 26. The path comprising lines 24, 30, 44 is terminated by resistor 52 while the path comprising lines 26, 31, 46 is terminated at both ends by resistors 53, 54. Nanosecond gates.-The gates 14, 15, Fig. 1 each comprises an avalanche transistor 62, Fig. 3, with its emitter coupled to the corresponding tap on the delay line via a fast switching diode 66; e.g. a hot carrier diode. When a zero value signal is applied to the digit input line, fast switching diode 63 is forward biased, connecting the base of transistor 62 to ground through a low resistance path; a narrow positive coincidence pulse on the coincidence pulse line will then cause transistor 62 to break down and apply a positive pulse to its output. If however the digit input line has a positive signal on it, diode 63 is cut off, the input impedance of transistor 62 high, and it is not rendered highly conductive by a positive pulse on the coincidence pulse line. Receiver gates.-The gates 33, 34, &c., Fig. 1, each comprises a first avalanche transistor 71, Fig. 4, coupled via a capacitor 73 to a second avalanche transistor 74. Coincidence pulses on the concidence pulse line only render transistor 71 conductive when there is not a positive pulse applied from the digit stream line to the cathode of diode 72, which is a fast switching diode. Transistor 74 is biased to be normally conducting, being driven non-conductive when transistor 71 conducts.

Title: Mobile radio systems
IPC: H04B7/08
Filed: 1971-12-23
Abstract: 1357779 Mobile radio systems WESTERN ELECTRIC CO Inc 23 Dec 1971 [29 Dec 1970] 59905/71 Heading H4L A base station transmitting to a mobile station (Fig. 1, not shown) through one of a plurality of transmitting antennae (25, 26) responds to a tone, transmitted by receiver (12) at the mobile station when its received signal fades below a certain level, by switching the base station output to another antenna. The base station also has a plurality of receiving antennae (20, 21) connected to a diversity receiver (22). Filters (31, 30) extract message and tone signals respectively the tone being above the message frequency band. At the mobile station a diplexer (13) connects the antenna to receiver (12) and transmitter (11), and the tone generator (28) is controlled by a comparator (27) responsive the output of the receiver (12). The comparator (27) responds separately to fast, multipath phase-cancellation type, fading and to slow fading due to terrain effects (Fig. 2, not shown). Slow fades are detected by comparing the means level (43) of the received signal with a fixed level (45) in a comparator 51, Fig. 3, whose output changes from one level to another when the mean level (43) falls below the fixed level (45) and disables a NAND gate 60 which triggers the tone generator 61. Rapid fades (42, 47) are detected by an amplifier 54 and envelope detector 64, having an a.g.c. circuit 55, 56 with a time constant short compared with the slow fade period and long compared with the rapid fade period. A rapid fade consequently produces a signal output from the amplifier large enough to cause another fixed level comparator 57 to generate an output disabling NAND 60 and initiating a tone signal at 61. To modify the a.g.c. time constant according to speed of the mobile station, R56 is varied by a counter 58 responsive to the number of fast fades, the frequency of which increases with speed. When a tone has been generated to select a different transmitting antenna, no further tone can be generated until both fast and slow fades have been corrected, since the NAND gate will produce no further change in its output of a suitable polarity until both its inputs have first been restored. This gives time for a new antenna and motion of the receiver to reduce the fading. If the mobile station is stationary however, and it is desired to continue selection of new antennae until a satisfactory signal is received, a switch 62 is closed and a timer 63 causes tones to be sent at intervals until the NAND is reset.
