Title: Data transmission systems
IPC: H04L7/04
Filed: 1972-02-25
Abstract: 1374357 Digital transmission; synchronization SIEMENS AG 25 Feb 1972 [18 March 1971 25 Jan 1972] 8870/72 Heading H4P In a synchronizing arrangement in which redundant bits are utilized, the redundant bits may also be used for synchronization of bit fault recognition. The blocks are received into a shift register having test circuits connected to individual cells which emit test signals on application of a series of timing signals if the bits in the shift register belong to the same block, there being as many trains of timing signals as possible data blocks. The outputs of the test circuits are passed to counters connected to a logic arrangement which determines which one of the timing trains are relative to the correct block. Preferably as many test circuits are provided as possible block arrangements. In a simple case each block B = 4 bits, the first and fourth being redundant bits which serve for synchronization. Trigger stages K1-K4 form a shift register having a test circuit P1-P4 connected thereto and a correct block arrangement exists when bit A1 = 0 and A4 = 1; the test circuits check bits in stages K1-K4 at different times. When correct lines h1-h4 emit Is or when incorrect this is signalled on lines g1-g4. Timing signals TB1-TB4 from LOG are supplied to terminals c of P1-P4. When inputs to half adder F are equal a O is emitted to AND gate U1 resetting counter AZ, also through inverter N1 to AND gate U2 which steps AZ forward; at max. count nAZ-# 1. Counters Z1-Z4 are stepped by signals a and reset by b ; at maximum count k a 1 is issued to LOG from which signals TA, TS, TB1-TB4 are derived. If the data bits A2, A3 have the values 0, 1, at time t3 a 1 is emitted from P3 through line h3 to Z3 thus a correct block arrangement is signalled. On the other hand incorrect blocks have no effect because counters are reset before arrival of the k counting pulse. Preferably A1, A4 are parity bits calculated from bits A2, A3 hence may be used for error correction in addition to block synchronization.

Abstract: 1339223 Selective signalling BURROUGHS CORP 29 Feb 1972 [1 March 1971] 9190/72 Heading G4H [Also in Division H1] A code signal sender has a plurality of electric switches scanned repetitively, and a shift register the number of stages of which is at least as many as the number of switches (as disclosed, this number plus one), a bit being entered into the shift register upon detection of a closed switch -and being shifted along to the last stage, gating means being responsive to the first and last stages of the shift register to transmit a signal representative of any closed switch detected by the scanning means when a "bit" appears only in the first stage but being inoperable to signal in such manner when a "bit" is concurrently present in both the first and last stage. Each electric switch is operated by a respective key on a keyboard, and the gating means prevents more than one signal per key actuation even though the key may be held actuated for more than one cycle of the scanning means. The scanning means is a "binary to 1-out-of-n" converter driven by a clock-fed binary counter, the signal from the gating means also gating the count to an output to identify the key actuated. If a "repeat enable" key is pressed, actuation of certain predetermined ones of the keys will produce repeated signals, either as long as the key is held actuated or until a predetermined number of repetitions has occurred. A keyboard construction is disclosed (see Division H1).

Abstract: 885,690. Positive clutches; change-speed gear. CHICAGO AERIAL INDUSTRIES Inc. March 24, 1958 [March 28, 1957], No. 9374/58. Class 80 (2). [Also in Group XX] A gear change is effected by a coupling having a spring tongue which can occupy one of two positions. In the form shown, gears 95, 96 are secured to the driving shaft 91. These gears mesh with gears 103, 104 which are rotatably mounted on, but not secured to, the driven shaft 17. Pins 119, 120 project from gears 104, 103 respectively. The coupling 107 has a body part 108 which is secured to, and may be integral with, shaft 17. This encloses a spring having a tongue 112, which engages in a notched pin 115. Pin 115 is normally in the position shown in Figs. 4 and 5, i.e. it engages behind pin 119, so that gear 96 drives gear 104 which in turn drives coupling 107 and hence shaft 17. When the spring tongue 112 is pushed across into its second position (Fig. 6), pin 115 moves clear of pin 119 and engages behind pin 120 instead. Thus shaft 91 now drives shaft 17 via gears 95, 103. The gear change is effected by an axially mounted selector pin 116, actuated by a solenoid 117, 118. Specification 868,200 and U.S.A. Specification 2,413,349 are referred to.

Title: Devices for conducting excess heat away from heat sources
IPC: G21H1/00
Filed: 1973-02-28
Abstract: 1458371 Conducting excess heat away from heat sources UNITED KINGDOM ATOMIC ENERGY AUTHORITY 19 Feb 1974 [28 Feb 1973] 9762/73 Heading F4U A device 1 for conducting heat away from a heat source 2 to a heat sink 3 comprises a plurality of relatively high heat-conductive bodies 4, 5 disposed in spaced relationship along a relatively low heat-conductive elongate housing or tube 6. As shown, the bodies are held in the tube 6 by thermally responsive fusible brazings 8, 9. The braze is selected so that it has a melting point at a temperature above the normal operating temperature of the heat source 2. In the event of the source 2 overheating, the brazing 8 around the upper "hot" end body 4, that is the body integral with a ball joint 7 located in a mating socket 12 in the source 2, melts allowing the body to drop under the weight of the heat source 2 down within the tube into engagement with the next adjacent body 5. Excess heat is then conducted away through both bodies 4, 5. This process may continue depending on the temperature until there is thermal contact between all the bodies 4, 5. In another embodiment (Fig. 2, not shown), the "hot" end body has a plurality of fingers which interfit in sliding engagement with fingers formed on the ball joint 7. The two sets of fingers are brazed together. The bodies are hollow and a tie member comprising a steel wire extends through the bodies between the "hot" end body and the "cold" end body and is tensioned by a spring. Should the heat source 2 overheat, the brazing securing the fingers softens and allows tension in the wire to pull the bodies into contact. The lengths of the fingers are so arranged that they always remain slidably engaged. In another embodiment (Fig. 3, not shown) the "hot" end body is formed with a central recess which houses a fusible plug. A tubular member extends through the hollows in the bodies to contact the fusible plug. Compression is applied to the tubular member by a spring fitting. The bodies are spaced apart by further springs. In this case, should the source 2 overheat, the plug softens, allowing the tubular member to move towards the heat source under the action of the spring fitting. A boss portion to which the "cold" end of the tubular member is attached compresses the bodies together, overriding the springs between the bodies. In a further embodiment (Fig. 4, not shown), the bodies are supported in a resilient frame in the form of at least two interacting helical springs having opposite pitches. The tubes may be filled with xenon or may be evacuated.
