Title: Circuit for generating cipher pulse series
IPC: H04L9/22
Filed: 1962-12-31
Abstract: 973,537. Ciphering telegraphic messages. GRETAG A.G. Dec. 31, 1962 [Jan. 10, 1962], No. 49150/62. Heading H4P. A circuit for generating a long series of cipher pulses to be mixed with message pulses for transmission comprises a binary counting chain with at least 20 stages interconnected as described in Specification 973,536, the outputs being mixed with the outputs of the stages of a shift register so that the signals resulting from the mixing of a stage of the counter with a stage of the shift register are passed to the next stage of the shift register. In the form of Fig. 2, the counter stages Z 1 -Zn have outputs E 1 -En which are applied to gates TE 1 -TEn controlled by a switching device SV. The shift register SR 1 -SRn has mixers MS 1 -MSn interposed between stages. The mixers each comprise a scale-of-two adder. The counter and shift register are stepped by timing pulses T 1 . The output of the last stage SRn of the shift register is further modified by a reducer stage consisting of a flip-flop U and a final mixer MU. The output then passes back to the first stage of the shift register and is also available at S1P for mixing with the message to be transmitted. An exactly similar circuit at the receiving end makes an identical series of pulses, which are subtracted from the ciphered message to effect deciphering. In Fig. 3, the outputs of the counter stages are mixed with the shift register outputs as before but in addition the stages are tested in pairs for coincidence and And gates KD 1 -KDn. The outputs are applied in combination to Or gates TD 1 -TDn for controlling the gates TE 1 -TEn. Another input 50 enables a further control of gates TE 1 , TEn to be imposed from another source. In another form there are three or more parallel shift registers to which ones of each successive group of three or more counter stages are connected. There are interconnections between the shift registers further to complicate the pattern. A series of cipher pulses is available from each shift register.

Abstract: 1415183 Pulse delaying circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 2 Nov 1972 [5 Nov 1971] 50547/72 Heading H3T [Also in Division G4] Fig. 3 shows one of a series of stations, each of which sends to the next station a delayed version of a pulse received. A negative pulse at 20 (left) turns on transistor TR 1  to charge C 1  to turn on TR 2  and keep it on even after the input pulse has ended. C 3  is charged via TR 2  and R 8  and when the potential at 34 reaches the Zener Z 2  voltage, TR 4  is turned on. The turning off of TR 1  at the end of the input pulse lowered the potential at 37 and thus at 36 via C 2  which was then charged via TR 2  and R 7 . When the potential at 36 reaches zero, TR 3  is turned off to turn off TR 4 . The on period of TR 4  produces the output pulse at 35.

Abstract: 1332135 Injection-moulding shoe soles BRITISH BATA SHOE CO Ltd 23 Oct 1970 [31 Oct 1969] 50593/70 Heading B5A Injection-moulding apparatus for shoe soles comprises two mould sections movable in different directions, means to grip and remove sprue remaining on the moulded shoe sole after moulding during the movement of that mould section carrying the sole, the sprue removal means being moved between an operative position and an inoperative position out of the path of this mould section. As shown in Fig. 1, upper mould section 12 is vertically reciprocable by piston 26 of cylinder 28 and has a cooling plate 30. Lower mould section 14 and cooling plate 20 are mounted on a carriage 2, reciprocated horizontally by cylinder 6. When the mould sections are closed, a member 49 contacts microswitch 48 to start injection through nozzle 45 into cavity 16 to form a sole 22 with sprue 46 thereon. When full, the upper mould section 12 is raised sufficiently to disengage micro-switch 48 to stop injection. After a cooling dwell period, upper mould section 12 is raised and air passed through ducts 42 therein to retain the sole 92 in the lower mould section 14. Carriage 2 is then retracted, and sprue gripping mechanism swung into position behind the mould section by means of cam surface (86, Fig. 5, not shown) on carriage 2 and cam follower (80). Jaws (62, 64, Fig. 7, not shown) of the mechanism are closed to grip the sprue and remove it on continued movement of the carriage 2, which passes under wiping blade 94. Air is supplied through passage 32 in the lower mould section 14, raising pins 35, 37, 39 and the moulded sole 92 thereon. On return movement of carriage 2, the heel portion of sole 92 engages the wiping blade 94 and is removed thereby from lower mould section 14.
Patent GB-506621-A (GB)
Abstract: 506,621. Phase - difference measurements. TELEFUNKEN GES. FUR DRAHT LOSE TELEGRAPHIE. Aug. 13, 1938, No. 23943. Convention date, Aug. 14, 1937. [Class 37] [Also in Group XL] Relates to circuit arrangements for indicating whether two voltages of the same frequency are of the same or opposite phase in which one of the voltages is periodically reversed in phase and the two voltages are then combined and applied to an indicator circuit. According to the invention, the indicator circuit includes a voltage source which alternately opens and closes two rectifiers in synchronism with the phase reversal of one of the alternating voltages, and the currents passed by these rectifiers bias two further rectifiers connected in series which rectify the combined alternating voltages to produce direct currents which traverse an indicating instrument in opposite directions. The invention is applicable to a "homing" radio direction finder and as shown in the Figure the pick-ups from the directional and non-directional aerials 2, 1 are alternately combined additively and in opposition by means of the switch 3 and are then heterodyned in the receiver 7<SP>1</SP>. Current from the alternating voltage source 23, which is synchronous with the switch 3, alternately passes through rectifiers 22, 21 and the biassing voltages developed across resistances 16, 15 alternately open and close rectifiers 19, 20 which alternately rectify the beat frequency output from the receiver 7<SP>1</SP> causing direct currents to traverse the indicating instrument 24 alternately in opposite directions. Alternatively the beat note may be rectified in the receiver 7<SP>1</SP> and the alternating voltage of switching frequency passed through the transformer 14. In order to reduce the effect of variations of the pass resistances of rectifiers 19, 20, the resistances 15, 16 are much higher than these pass resistances. One or both of the resistances 15, 16 may be variable to facilitate balancing. Similarly to avoid errors due to variations in the rectifiers 21, 22, may be provided in series with the source 23, Figs. 4 and 5 (not shown). A known form of "homing " receiver is described in which it local voltage of switching frequency and the alternating signal from the aerials are to a dynamometer indicator.

Abstract: 1,103,358. Electro-physical measurement. RICHARDS FOUNDRIES Ltd. Nov. 14, 1966 [Dec. 11, 1965], No.52713/65. Heading G1N. The composition of a sample of metal, e.g. the silicon content of iron, is determined by measuring the thermoelectric potential generated by a heated and a cold electrode in contact with the sample, the temperature difference between the electrodes being automatically maintained constant. The sample 5 is contacted by hand-held electrode assemblies 2. The heated electrode assembly, Fig. 2 (not shown) consists of copper tip 9 on a steel shaft which carries an electric heating element 10. The tip is connected by lead 19 to one side of a mirror galvanometer 3, the other side of which is connected to the copper tip of the unheated electrode assembly 2 so as to measure the thermoelectric potential of the two thermojunctions formed with the sample 5. Embedded within, but electrically insulated from, the unheated tip is a copper/constantan thermocouple 26, Fig.3 (not shown), the output of which opposes the output of a thermocouple formed by welding a constantan wire 15 to the heated copper tip 9. The difference between these signals controls an automatic regulator 4 to cause the heater 10 to be intermittently energized so as to maintain a constant temperature gradient between the two copper tips. In a modification, Fig.4 (not shown) the unheated electrode is constituted by a copper cup into which the sample to be measured can be placed in the form of powder or drillings.
