Abstract: 1,060,835. Selective punching apparatus. OLYMPIA WERKE A.G. Dec. 4, 1963 [Dec. 24, 1962], No. 47868/63. Heading B4B. In apparatus for punching recording media in the form of tape or marginal punched cards in which the punches advance the recording medium through the punching station and perform for this purpose a rocking movement in the direction of feed and back again in addition to their punching movement and are adapted for selection by setting members for each punching operation, the feed rocker 3, which acts as a guide 3a, 3b for the punches 4 and at the same time as a matrix 5, is provided to impart the feed and return movements to the recording medium 7 and the punching and restoring movements of the punches and the drive of the rocker are separately derived from a drive shaft 14 in such a manner that the entry and exit of the punches into and from the recording medium take place regardless of its thickness when there is no relative movement between the rocker and the recording medium. The rocker is driven by means of a roller 25 engaging a cam 24 on the shaft 14. The cross-bars 3a, 3b of the rocker are connected to one another by lateral bars 3c which carry bearing extensions 8 for bolts 9 about which the rocker swings, the extensions 8 being arranged at the centre of gravity of the rocker. The recording medium is held during the return movement of the rocker by means of fixed and movable clamping jaws 27, 28, the jaw 28 being driven by means of a cam 38 on the shaft 14 which engages a roller 37 on a lever 36 carried by a shaft 35 to which is connected a cam 34 which coacts with a cam surface 28c on the jaw 28. The clamping jaws may be replaced by a pin which is driven by a cam on the drive shaft and intermediate members and which engages one of the feed holes in the recording medium and so ensures that the recording medium is held in position when it is stationary.

Patent GB-493632-A (GB)
Abstract: 493,632. Roller driving-gear for producing slub yarns. GROGAN, D. April 24, 1937, No. 11777. [Class 120 (ii)] In the manufacture of slub yarn an intermittent variation in the normal relative speeds of the front delivery and the back feed rollers' is obtained by mechanism controlled by an electromagnet the actuating circuit of which is closed and opened by a switch operated at irregular intervals. Where a number of machines are employed each may have a control switch, or all the machines may be controlled from one master switch. A shaft 25 carries a drum 1 with an helical groove 2 in which are secured studs 3 which close contacts 41, 42 in the carrier 6 as the drum rotates. The carrier 6 is moved parallel to the drum axis by a screw 5 rotated in one direction or the other by means of bevel wheels 12, 13 from the bevel wheel 11 on the motor shaft 10. As the carrier approaches the limits of its travel it operates a lever 45 to compress a spring 48, and then releases the end 51a, of the catch 51 from the collar 50 so that the spring actuates the rod 17 to operate the reversing lever 14 of the bevel wheels. The carrier 6 has two parts joined by a hinge 39 ; the part 38 is threaded on the screw 5 and the part'37 is held away from the other part by a spring 40. The studs 3 are arranged irregularly and whenever one passes the roller 43, the contacts 41, 42 in the actuating circuit of the solenoid 53 are closed. The drum 1 is driven from the screw 5 through gearing 18, 19, 23, 26, and the linkage system 21, 29, 24 associated with the gear wheels enables the independent rotation of the wheel 31 to oscillate the centres of the gear wheels 19 23 to produce intermittent variations in the speed of the drum 1. Where the slubs are produced by accelerating the feed of the yarn, the solenoid 53, Fig. 3, when energized, lifts its core and raises the bar 57 ; this causes the pawl 62 to engage the teeth of a wheel on the back roller 61 and so increase temporarily the speed of this roller relative to the front roller 67. The pawl is restored by the spring 64 to its position against the adjustable stop 65 when the solenoid core drops. Where the slubs are produced by intermittently slowing up the front roller, the driving clutch is disengaged by forks operated each time the solenoid is energized.

Filed: 1971-10-25
Abstract: 1361032 Electrophonic musical instruments WURLITZER CO 25 Oct 1971 [12 Nov 1970] 49472/71 Heading G5J A musical instrument comprises a plurality of key switches connected to means producing a repeating train of pulses, with a repetition rate dependent upon which key is operated, and integrating means connected to the pulse producing means to generate an audio-frequency electric wave corresponding to a musical tone. In one embodiment, Fig. 2, the pulse train is produced by means of a shift register 34 connected to a counter 42, the shift register and counter being driven from the same clock 36. Each key on the keyboard is associated with a respective switch 24 which is connected to one stage of the shift register, each stage of which is connected by a bus 40 to the counter. Upon closing a key switch the shift register shifts to the corresponding stage and the output from that stage of the shift register causes the counter to dump its count on to the line 46. The line 46 is connected through a distributer 48 to a succession of buffer memories 50 the number of buffer memories being dependent upon how many notes it is required to play simultaneously. Each buffer memory is connected to a variable clock 52, the variable clocks being controlled by a master clock, and the output of each variable clock is connected to an N-state register 54. The train of pulses supplied via the distributer passes through the N-state register and the density of pulses is controlled by means of a feedback matrix 56 connected to the register, the feedback pattern itself being controlled by means of a plurality of diode switches 60 and the pattern may be preset to give the desired pulse train at the output of the register. Integrating means 64 connected to the output of the shift register produce an audio-frequency output which is then amplified and connected to a loud-speaker. In a second embodiment, Fig. 7 (not shown), in order to produce the appropriate pulse repetition rate the octave and note position within the octave of each key is represented in digital form, the pulse train being produced by means of a master clock associated with a plurality of gates, the gates being connected to the key switches and the output of said gates being connected to a divider. The output from the divider is then connected to the N-stage shift register as before.

Abstract: 1,090,824. Controlling reactors. ATOMENERGI A.B. Dec. 8, 1964 [Dec. 20, 1963], No. 49938/64. Heading G6C. Shutdown and / or reactivity control, in a reactor having forced coolant circulation, is achieved by means of a neutron absorbing body in a tube passing through the core, the position which the body adopts being determined by coolant flow conditions; the tube is open at its lower end, the upper end being at a point in the reactor at lower coolant pressure and the lower end at a point of higher pressure, so that under normal coolant flow the body is situated in the tube above the core, but when coolant flow is reduced, the body sinks to a position in the tube within the core. Fig. 1 shows the reactor 1 combined with a heat exchanger 7, there being a roller bearing 21 between them to permit lateral movement. Water coolant passes from pump 11 through the core (dotted) within a tube 14 and thence through the heat exchanger within U-tubes 10, downwards through the outer core zone to the pump 11. The neutron absorbing bodies 32 are boron steel or silver-cadmium-indium alloy spheres, and their containing tubes 30 are of zircalloy; alternatively they may be of cylindrical shape. The invention is also applicable to gas cooled reactors. In Fig. 2 (not shown), the tubes 30 pass to the low pressure zone of the coolant circuit via a control valve, by means of which the reactor may be shut down, or power control achieved, by varying the position adapted by the train of spheres 30; the train, when withdrawn, from the core extends into a closed end pipe beyond the point at which coolant leaves the pipe 30.
