Title: Improvements in locking means for nuts and bolts
IPC: F16B39/12
Filed: 1923-04-27
Abstract: 197,324. HÚreng, A. May 8, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Locking nuts and bolts.-A lock-nut comprises two nuts A, B threaded one upon the other, the intervening thread being of greater pitch than that on the bolt c. The surface of the nut A nearest the work d is roughened. To lock the device, the nut B is screwed gently against the surface d and then the nut A untdl the roughened surface engages the work. The nut B is then screwed strongly in the opposite direction. The same principle may be applied to lock a bolt-head, in which case the outer nut is threaded around the head.

Abstract: 178,863. Hasler Akt.-Ges. vorm. Telegraphen - Werkstõtte von G. Hasler. April 23, 1921, [Convention date]. Periodic-counter speed indicators.-A shaft 1 driven from the shaft whose speed is to be measured carries a loose pinion 4 having a clutchfaced collar 5, the pinion being moved axially into and out of engagement with clutch faces 8 fast on the shaft 1 by a lever 10 having a roller 12 bearing against a cam surface 14 on a uniformly driven shaft 2. A similar lever 16 carries a locking surface 17 adapted to engage locking teeth 7 on the collar 5 just after the clutch has been disengaged, the rollers 12, 18 of the two levers being coaxial but slightly to one side of the axis of the shaft 2. The pinion 4 gears with a loose positioning wheel 21, which tends to return to a zero position with a lug 23 against a stop 24 under the action of a spring 22. A wheel 25 fast on the indicator spindle carries a pin 26 which is engaged by the lug 23 of the wheel 21 while the clutch is engaged and the pinion 4 is driven, the wheel 25 being moved to take up a position dependent on the speed. This wheel is free to move in the direction of increased speed, but its return movement is controlled by a locking-wheel 27. 28 which is engaged by a locking-lever 29 during the time the driving clutch is engaged, the lever being actuated by tappets 31 on the cam-shaft 2. The wheel 25 and indicator thus remain steady during the measuring intervals. The shaft 2 is driven from the shaft whose speed is to be measured through a regulating device such as an escapement.

Title: Positive and constant-tension warp letoff mechanism for textile machines
Inventor: CLENTIMACK GEORGE ERNEST
IPC: D03D49/06
Filed: 1951-05-16
Abstract: 714,690. Hydraulic clutches. WHITIN MACHINE WORKS. May 16, 1951, No. 11492/51. Class 69 (2). [Also in Groups VIII, IX and XVI] A shaft 51, driving a warp beam shaft 65 through worm and worm gear 50, 60 carries a member 75, contoured to conform with the annularly recessed opposing faces of a constantly rotating clutch member 40 and a stationary brake member 70 : the members 40, 70, 75 are immersed in oil and member 70 is so positioned axially by a screw 55 that the oil drag between members 40 and 75 drives shaft 51 against the drag between members 70 and 75. An increase in yarn tension causes gear 60 to force shaft 51 to the right, against the action of a return spring 85, to increase the driving torque and decrease the braking torque, to speed up the shaft. The spring 85 may be adjusted initially by means of a thimble 89. The force of spring 85 is also reduced automatically as the yarn is consumed For this purpose, the shaft 65 carries a cam 140 by which a pawl 131, carried on a lever 137, is caused to rack round a shaft 114 to an extent determined by a screw 145. The shaft 114, in turn, carries a cam 115 which acts on a pawl 105, through link 111, to rack round a worm 100 to an extent determined by a screw 120. The worm 100 rotates a worm wheel 95, which has screw threaded engagement with a cylinder 83 containing the spring and which, as it is rotated, allows the cylinder to slide to the right. The clutch member 40 is rotated from the knitting-machine cam shaft. The pawl 105 may be raised clear of its ratchet, to permit manual reverse rotation of worm 100, by rotating a threaded knob to raise a collar 122 through which the link 111 slides.

Title: Data processing apparatus
IPC: G06F9/48
Filed: 1971-04-27
Abstract: 1343072 Data processors; interrupt WESTERN ELECTRIC CO Inc 27 April 1971 [27 April 1970] 11538/71 Heading G4A A digital electric data processing system has one or more interruptible units, there being circuitry for measuring the time that elapses between the receipt of the interrupt signal by a unit and the completion of processing by the unit. In the preferred embodiment interrupt in the synchronous units of a system is effected by stopping a master clock and interruption of asynchronous units is effected by measuring and recording the time taken for the asynchronous units to complete their respective current operations. The recorded data is used in restarting the system. The asynchronous units 202-1 to 202-M. These may be any systems where the output is delayed for some period after the input, e.g. a delay line (Fig. 1, not shown), a magnetic drum or a magnetic disc. The system.-The asynchronous units are connected to interrupt sources 200-1 to 200-N through a control unit 201 which may operate immediately or after a delay, and to respective reversible counters 230-1 to 230-M. When an interrupt is received further interrupts are inhibited, control unit 201 starts a local clock 225 which feeds the counters 230-1 to 230-M and each of these is incremented until its corresponding asynchronous unit has finished operation. Thus each counter will measure the time elapsed between receipt of the interrupt and completion of processing. The counter contents may be transferred to a memory 250. Restarting.-The counter contents are returned to the counters and each counter is counted down till it reaches zero, each asynchronous unit rejoining the system when its respective counter reads zero.  Other features mentioned include telephones, magnetic core or integrated semi-conductor memories and shift registers. A combined asynchronous unit and data generator is also described (Fig. 4, not shown).

Title: Improvements in mechanism for controlling the direction of rotation of synchronous electric motors
IPC: H02K7/118
Filed: 1939-04-18
Abstract: 527,673. Locking synchronous motors against backward rotation. ELMS, R. April 18, 1939, No. 11737. [Class 35] To prevent backward rotation the shaft 2 of a synchronous motor driving an electric clock is fitted with an eccentric 1 which reciprocates a rod 6. If the rotation is in the direction of the arrow the rod slides freely over the lower pin 13. If the rotation is in the opposite direction a friction washer swings the rod against the upper pin 14 which catches a shoulder 7, and thus stops the motion. With another form of device, reversal of rotation slightly tilts the axle of a friction spring bears upon the flat side of an idly rotating toothed wheel which upon reversal of rotation jams against a fixed pin.

Abstract: 1,161,956. Extruding tubing. V. MORRILL. 11 March, 1968, No. 11742/68. Heading B5A. [Also in Division C1] In a method of continuously forming highprecision tubing, a heat-softenable material is melted and then flowed between smooth surfaces of a vertically adjustable die 35 and a mandrel 36 and over the mandrel to form a tube, the tube then being drawn away from the die and mandrel and over a control member 37 within the tube while at the same time cooling the tube and flowing a gas through an annular zone between the tube and the control member, the flow of gas being regulated through the zone to control the final dimensions of the tubing, the tube being continually drawn away from the control member, its cross-section being reduced until the tube has cooled sufficiently for it to be no longer ductile under the drawing effort. Any change in the gas pressure flowing through the annular zone is automatically detected and this is corrected simultaneously with any changes in rate of material feed to be melted, melting temperature and molten material level. The die, mandrel and control member are rotated. A rod (104), Fig. 2 (not shown), of heatsoftenable material is regulably fed into the cup of die 35, is firstly preheated by an electric resistance source and a variable gas source (120) and is then melted by two sources, a high-frequency (or radio-frequency) induction heater and a controllable gas heater (120<SP>1</SP>), Fig. 17, not shown.
