Patent GB-789915-A (GB)
Title: Improvements in or relating to record controlled statistical machines
Inventor: PARMENTER RAYMOND OWEN
Filed: 1955-12-28
Abstract: 789,915. Statistical machines. POWERSSAMAS ACCOUNTING MACHINES, Ltd. Nov. 12, 1956 [Dec. 28, 1955], No. 37164/55. Class 106 (1). In a statistical machine of the kind having a reciprocable pin-box having columns of sensing pins 29, Fig. 3, for sensing the columns of the record cards, an intermediate element 31 and a set pin 30 for each sensing pin, the intermediate elements 31 being movable to an active aligned position when the sensing pin senses a perforation and a shutter element 32 being appropriated to each column of intermediate elements to prevent or permit them to move to the aligned position and to reset them after each sensing operation, each shutter element is controlled by a pair of arms 8 or 9 pivotally mounted in a unit 1 which can be detached from the machine to allow the appropriate elements to be manually set. The unit 1 has pivot pins 16 at each end which engage in bearing slots in a framework attached to the machine. The bearing slots are closed to retain the pins by the operation of a lever at each end, and the levers are connected together by a cross bar for simultaneous operation. The sensing mechanism is adapted to sense normal and interstage perforations and to allow a column of sensing pins to be active for sensing one set and inactive for sensing the other, the unit 1 is rocked by means of a solenoid to bring one arm 8 or the other 9 into latching engagement with the shutter. The arms are set by inserting a key between appropriate guide plates 7, the key having pins adapted to engage locating slots 35 in these plates. There are three keys to prevent sensing of a column of pins under three different conditions. Fig. 9 shows a key 33a having a nose 36 engaging a recess in arm 8, the unit being rocked to bring this arm into engagement with the shutter when the machine is set to sense normal positions. This prevents sensing of normal card positions in the column controlled by the shutter but permits interstage positions to be sensed the unit being in the upright position when the mechanism is set for such sensing, so that the arm 8 is out of the path of the shutter. In Fig. 10 a different key 33b engages arm 9, the unit being in the upright position for sensing interstage positions so that this arm engages the shutter. This prevents sensing of the corresponding card column in when sensing interstage positions, but allows normal positions to be sensed, the unit being rocked by the solenoid for such sensing so that the arm 9 clears the shutter. The third key has projections engaging both arms so that one or the other engages the shutter whether the unit is rocked for sensing normal positions or not. Accordingly no sensing takes place in the corresponding card columns. Specifications 401,012 and 473,757 are referred to.

Title: Improvements in or relating to high-current pulse systems
IPC: G05F7/00
Filed: 1964-09-15
Abstract: 1,086,852. Charging and discharging capacitors; rectifying. GENERAL DYNAMICS CORPORATION. Sept. 15, 1964 [Sept. 25, 1963], No. 37624/64. Headings H2F and H2H] A magnetic forming coil 8 is energized by the closure of a contact 34a causing a discharge of capacitors 6 through resistors 29, which being connected to the igniters of ignitrons 31 cause them to fire and discharge the capacitors through the coil. Recharge of the capacitors 6 is initiated by closure of a switch 2 which through a tuning circuit 3 discharges a capacitor 109 through the upper winding of a bi-stable relay 73, closing a contact 73b which energizes the relay 34 and opens contact 34a. This removes a short circuit from the rectifier 22 output and from a network 36-38 across the capacitor 6. When the threshold voltage of the Zener diode 38 is reached, a transistor 49 normally maintained non-conductive by reference circuit 9 is rendered conductive thus switching another transistor 51 to its non- conductive state energizing the lower coil of relay 73 which closes contacts 73a and deenergizes the relay 34 to discharge the capacitors 6. By means of a tuning capacitor 117, resistors 111-113 and unifunction transistor 118 in circuit 3 the capacitor 109 is prevented from recharging until a determined time delay to prevent the circuit resetting until the capacitors 6 have had time to discharge. Continued pressure on the switch 2 will cause a succession of spaced pulses through the coil 8. An overload protective circuit includes a winding 18c tightly coupled to winding 18b which when the voltage thereacross rises to a value determined by autotransformer 122 and a Zener diode 124, energizes a bi-stable relay 20, 20a which de-energizes another relay 19 which disconnects the supply also de-energizes relay 34, thereby discharging the capacitor 6 through the work coil due to contact 34a closing. The circuit is reset by a switch 125.

Abstract: 1431107 Mandrels for yarn winders MASCHINENFABRIK RIETER AG 10 Aug 1973 [7 Sept 1972] 38034/73 Heading DIJ A sleeve 2, for a tube 11 on which a package is to be wound, carries at one end yarn cutting ring 6 that has circumferentially extending teeth 12 pointing away from the end face of the tube 11, each tooth having an inner cutting edge 16, Fig. 2. Facing the ring 6 is a yarn catching ring 4 that has a conical yarn guide surface 17, this surface 17 extending at least partly under the teeth 12 when the tube 11 is pushed fully on the sleeve 2. The rings 4 and 6 also act as yarn clamping means. The yarn clamping means may be a gap between the rings 4 and 6. This gap (19), Fig. 3 (not shown) may be a rectangular one. In Fig. 4 (not shown) the gap (23) is V- shaped. In Fig. 5 (not shown) the gap (25) is defined by the boundary between a conical surface (24) on the ring 4 and a resilient ring (27) on the end face of the ring 6. The invention is applicable to co-axial bobbins when used for winding-up continuously supplied yarn. As the yarn leading to a fully wound package is moved across to the empty sleeve 2 it slides over the conical surface 17 into the yarn clamping gap (19, 23 or 25) and hence into the range of the teeth 12 where the yarn is cut. At the same the yarn passes through the gaps between the teeth 12 and onto the tube 11 where reserve windings 32 are first wound. After these reserve windings have been applied a package 33 is built up by establishing a regular traversing stroke.

Filed: 1969-07-30
Abstract: 1,216,796. Feeding sheets. INTERNATIONAL BUSINESS MACHINES CORP. 30 July, 1969 [22 Aug., 1968], No. 38211/69. Heading B8R. In card-feeding apparatus wherein two members 34, 36 define a throat gap 38 allowing one card only to be fed forward from the top of a pile 14, the members 34, 36 are carried by a frame 40, 42, 44, Fig. 4, pivoted at 60 to permit the members 34, 36 to have limited rotation about an axis parallel to the plane of card feed. The arrangement allows the gap 38 to move to accommodate warped cards whilst still preventing the passage of more than one card. The pile 14 is spring-pressed upwardly against an oscillating or rotary separator member 26, and the member 36 rests on the top card of the pile whilst the member 34 abuts against the front edge of the pile. The pivot 60 as shown is constituted by a thinned part of a plastic block 54, one section 56 of which is fixed to the main frame 32 and another section 58 to the frame member 40. With unwarped cards, the gap 38 would be horizontal and approximately in line with the pivot 60. If the cards are warped, the gap would be above or below the horizontal position depending on the direction of the warp in the cards. The member 36 may be adjustably mounted on the frame 42 so that the size of the gap 38 may be varied. The member 36 may be spring-biased against the top of the pile 14.
