Patent GB-195648-A (GB)
IPC: B23P15/32
Filed: 1923-04-03
Abstract: 195,648. Wingfield, B. R., (Assignee of Hibou, E., and Schmidt, A.). April 3, 1922, [Convention date]. Shaping helical surface.-Twist drills are formed by a planing process wherein the blank, which is simultaneously fed forward and rotated, is passed between a pair of oppositelydisposed tools which form the flutes and relieve the cutting edges in one operation. The base plate 1 carries a support 2 having tool slides 3, 4 operated by a right and left-hand screwed spindle 5 and carrying spring-controlled tool-holders on which the tools 8, 9 are mounted. The spindle 5 carries a ratchet wheel 11 operated to feed the tools at each forward stroke of the reciprocating work spindle 19 by means of a pawl 13 mounteo. in a holder 12 actuated bv a lever 20. On the reverse stroke the feed pawl is disengaged by its head sliding over a curved arm 16 while the wheel 11 is prevented from moving backward by a second spring- pressed pawl 15. The feed continues until the desired groove depth is attained whereupon an adjustable stop 22 on the wheel 11 moves the pawl 15 so that it is disengaged by a stop on the pawl-holder 12. The spindle 5 is then returned by a spring 18, the pawl 15 being re-engaged on the next stroke for a fresh series of operations. A frame 24 on the base plate is provided with screwed bearing bushes 25 for the threaded spindle 19 which is driven from oppositely rotating pulleys 26, 28 mounted on the hub of a disc 27 feathered to the spindle. The pulleys may be engaged by keys 32 to drive the spindle in either direction, the keys being automatically actuated from adjustable collars 37, 38 acting through levers 39. During normal working a spring-controlled plate 46 is interposed between the collar 37 und its lever so that the length of stroke is limited to that required for cutting the grooves. On completion of the grooves the plate 46 is automatically moved by a lever 48 during the return of the feed-spindle and the longer stroke then obtained serves to take up a fresh blank. The blanks are transferred from a hopper 60 by a grooved drum 61 controlled by a wheel 62 actuated to allow one blank to drop into the bore 65 of the feed chamber at each long return stroke, the blank being subsequently enclosed by a guide-tube 67 actuated from the collar 38. On the next long return stroke the chuck is automatically opened by levers 57 and the blank transferred from the tube 67 to a second guidetube 54 mounted in the work-spindle. During its transfer to the tube 54 the blank is prevented from moving backwards by a fixed rod 71.

Title: Improved liquid-pressure relief valve for liquid filters
IPC: F16K47/00
Filed: 1953-04-07
Abstract: 734,965. Fluid-actuated valves. GENERAL MOTORS CORPORATION. April 7, 1953 [April 16, 1952], No. 9315/ 53. Class 135. A relief valve, e.g. acting as a by-pass valve for a liquid filter, comprises a valve stem 30 carrying a head 32 pressed by a spring 36 on to a seat 26, the head being so shaped relative to the valve through passage by an adjacent washer 34 that liquid flow, when the valve is open, produces an unbalanced lateral force on the head to move it laterally against an adjacent fixed valve part, e.g. the casing, whereby valve chattering is damped. An eccentric washer 34 having one side flush with and the opposite side overhanging the head is placed on the stem between the spring and the head, thus making the head asymmetrical so that the flowing fluid produces the lateral force on the head. The overhanging portion may be formed as a bevelled or per. pendicular thickened lip.

Title: Patterning system for knitting machines
Inventor: SUTTON JACK
IPC: D04B15/66
Filed: 1965-03-05
Abstract: 1,091,547. Programmed control of knitting. G. STIBBE & CO. Ltd. March 7, 1966 [March 5, 1965], No.9374/65. Heading G3N. [Also in Division D1] In a knitting machine, equipped with individually operable knitting needles, the needles are controlled by butts disposed in a multiplicity of planes, so that the butts in any one plane are well spaced apart with appropriate time intervals between, the butts are displaced by electro-magnetically operated devices arranged in the butt planes which are responsive to signals derived by electronically scanning the information borne by a pattern control means. As shown, the rotary cylinder and dial machine comprises a cylinder 1 in which are cut tricks 1a receiving a corresponding number of needles. Each needle is formed with a butt acted upon by cams mounted in a cam box supported on a plate 6. Beneath each needle a rockable control jack has an operating butt at its lower end and is provided with a plurality of frangible selector butts which are broken off so as to leave only the butt which is at the appropriate height. Each electromagnetically operated butt depressing device 28 consists of a pivoted cam 29 having a latch 30 which is coupled by a link 31 held by a tension spring 33 to a miniature solenoid 32. When a cam is projected inward to the surface of the cylinder 1, just after a selector butt has passed, it is held so as to press the following selector butt into the cylinder and then withdrawn before the third butt arrives. The relevant jack and needle will not then be raised by the raising cam at the feed and hence the needle will not knit. The solenoids 32 are disposed in groups in recesses formed laterally in vertical housing blocks 34, which are inclined so that the latches 30 are spaced vertically at equal intervals. The electronic pattern scanning system is responsive to a transparency which is scanned by a cathode ray tube whose X and Y scan generators are synchronized by the outputs of photo-electric cells responsive to the light from a source L shining through holes 44a drilled in a disc 44. The pulses derived from the cathode ray tube are routed through a matrix and a magnetic core store Figs. 11, 11A, 12, 12A, (not shown), to the solenoids 32.

Title: Variable speed power transmission for vehicles
Inventor: DUNDORE MARVIN WALTER
IPC: F16H61/14
Filed: 1956-03-26
Abstract: 803,444. Operating friction clutches. TWIN DISC CLUTCH CO. March 26, 1956, No. 9389/56. Class 80 (2). [Also in Group XXIX] A hydrodynamic convertercoupling comprises a pump 17 driven by an input shaft 15, a reaction member 27 mounted through a forward - over-run clutch 34 on a stationary member and turbines 19, 20 fast on a sleeve 22. An hydraulicallyoperated clutch 45 couples the sleeve 22 to an output shaft 49 to give hydraulic drive, and an hydraulically-operated clutch 57 couples the input shaft to sleeve 22 so that direct drive is obtained when both clutches are engaged. Liquid from the converter is continually passed through a cooler; an enginedriven pump 63 supplying oil from a sump 65 through pipes 75, 77, an annular passage 32 and ports 33 to the working circuit, and liquid draining from the working circuit outside of the carrier disc of the reaction member through a space 79, passage 80 and a pipe 81 to a cooler 82, from whence liquid passes through a pipe 83 and a pressure-regulating valve 84 to the sump. When the converter is functioning in its torque multiplying range the pressure in the working circuit increases flow through the cooler, and part of the oil leaving the cooler passes through a by-pass 87 directly back to the converter inlet pipe 77. Pump 63 also supplies liquid for actuating the clutches 45, 57, liquid passing through a pipe 67 and a distributing valve 68 to annular cylinders 41, 42 containing pistons for engaging the clutches 45, 57, respectively. The rate of engagement of the clutches is determined by means of throttles 69, 72 and an accumulator 70 interposed between the pump 63 and the distributing valve. A pump 89 driven from the output shaft 49 enables the vehicle engine to be started by pushing the vehicle, under which conditions pump 89 furnishes pressure to engage both clutches. The converter - coupling is particu-  larly intended to be used in conjunction with a sliding gear transmission and may be used in the drive of a crawler type tractor. Gear change is effected with the valve 68 in its neutral position, so that both clutches are disengaged, and the drag imposed by the pump 89 slows the output shaft sufficiently to facilitate gear shift.

Title: Improvements in distributor arrangements for multi-channel communication systems
IPC: H04J3/04
Filed: 1945-04-07
Abstract: 635,476. Thermionic distributers. STANDARD TELEPHONES & CABLES, Ltd., and LEVY, M. M. April 17, 1945, No. 9638. [Class 40 (v)] [Also in Group XL (b)] In a thermionic distributer, the channels are selected by means of a pair of pulse trains whose frequencies are different harmonic multiples of the distributer frequency. Pulses of the first frequency (e.g. 100 kc/s.) are produced by the oscillator 1 and pulse-forming circuit 3, pulses of the second frequency (e.g. 110 kc/s.) being derived by means of the locked multivibrator 5, selective amplifier 6, and pulseforming circuit 8. The channel gating means, 14<1> ... 14<10> operate in sequence and at the distributer frequency (e.g. 10 kc/s.) upon the reception in simultaneity of impulses from the circuits 3 and 8, the relative timing being determined by the delay network 10 following the circuit 8. In a modified arrangement (Fig. 3, not shown), the amplifier 6 and pulseforming circuit 8 are replaced by a synchronized multivibrator stabilized by the network 10 in the manner of Specification 578,690. Alternatively, both pulse trains may be derived in known ways from an oscillator operating at the distributer frequency (10 kc/s. as illustrated). In a modified arrangement (Fig. 4, not shown), for example, as a receiving distributer in a multiplex system, the oscillator. 1 is replaced by a selective amplifier to which the synchronizing pulses are applied. Specifications 587,939, 635,472 and. 635,474 also are refered to.
