Title: Clutch mechanism
IPC: F16D13/68
Filed: 1962-03-20
Abstract: 971,654. Friction clutches. BORG-WARNER CORPORATION. March 20, 1962 [March 24, 1961], No. 10713/62. Heading F2C. Free axial movement of a clutch driven disc 13 under its own weight on its splined and downwardly inclined shaft 16 when the clutch is disengaged is prevented by a semi-circular wire spring 30 having inturned ends 32 passing through radial holes in the disc-hub 15 to engage the shaft 16 frictionally. In a motor-vehicle with a rearwardly inclined engine, this prevents the disc 13 from sliding rearwardly under its own weight into spin engagement with the presser plate 18, which could otherwise render difficult the engagement of non-synchronized first and reverse gears from rest.

Title: Improvements in or relating to phase comparing or measuring apparatus
IPC: G01L3/10
Filed: 1945-04-27
Abstract: 601,460. Phase difference measurements. MITCHELL, J. H. April 27, 1945, No. 10720. [Class 37] [Also in Group XXXVIII] In an apparatus for measuring the phase relationship of two alternating sources having the same widely varying frequency, the outputs of these sources are mixed with the output of a third. alternating source having a different frequency and phase angle to obtain two outputs at a reduced frequency, out with a similar phase relationship for application to a phase measuring means. In use for torque measurement, the apparatus comprises two identical phonic wheels 3 and 5 and a dissimilar phonic wheel 4 mounted at each end and in the centre respectively of a torque transmitting shaft 1 with the teeth of phonic wheel 3 arranged in line with the spaces on phonic wheel 5 corresponding to 180 degrees phase displacement at zero torque. When the shaft 1 is transmitting torque phonic wheels 3 and 5 operating in conjunction with pick-ups 6 and 8 respectively, produce alternating E.M.Fs. having equal frequency variation, but a phase difference which depends on the torque. The two outputs thus obtained are each mixed respectively in apparatus 9, 10 with an alternating E.M.F. having a different frequency and phase angle produced by phonic wheel 4 in association with pick-up 7 to obtain two alternating outputs at a reduced frequency equivalent to the frequency difference between that of the supplies from pick-ups 6 and 7 and 8 and 7 respectively. The sinusoidal waveforms of the two outputs from apparatus 9, 10, after amplification in circuits 11, 12 are converted by means of squaring thermionic valve circuits 13, 14 and differentiating valve circuits 15, 16 into two trains of negative pulses which are fed to a low-frequency multivibrator 17 having two stable conditions of current output so thatwhen the phase relationship of the supplies from the outer pick-ups 6 and 8 alters in accordance with the torque transmitted, the two trains of negative pulses alter in phase relationship correspondingly and cause the multivibrator 17 to remain in one condition of output longer than in the other, the difference between the mean current outputs of the multivibrator 17 is therefore proportional to the torque transmitted by shaft 1 and measurable on a meter 18 which may be directly calibrated in lbs. feet. In a modified arrangement for use when the shaft 1 is subjected to high torsional oscillations, the multivibrator output currents are fed to low-pass filters 19, 20 and the resultant waveforms recorded by means of a cathode-ray tube 21 and a camera 22.

Title: Improvements in electric circuit arrangements for supplying luminous electric discharge devices
IPC: H05B41/232
Filed: 1935-04-06
Abstract: 453,446. Supply systems for discharge lamps. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London.-(Patent- Treuhand Ges. fur Elektrische Gl³hlampen; 11, Ehrenbergstrasse, Berlin) April 6, 1935, No. 10743. [Class 38 (iv)] Flickering of a luminous electric discharge device supplied from an alternating or intermittent source a, Fig. 1, is prevented by supplying an impulsive voltage b coinciding with the minimum values of the source. The discharge device 2, Fig. 2, is fed with alternating or intermittent current from terminals 3, and the circuit includes a stabilizing choke 4 and the secondary 5 of a transformer, the primary 7 of which is fed through a resistance 9 from terminals 8 supplied from the same source as the terminals 3, but through a phase shifting device, not shown. A condenser 10 and discharge tube 11 are connected across the primary 7 so that when the voltage across terminals 3 falls to a minimum, the voltage across condenser 10 attains the starting potential of tube 11 and the condenser discharges through the tube. The consequent change of voltage across the primary 7 induces the required impulsive voltage across the electrodes of the discharge device 2.

Title: Method and apparatus for binding loose sheets
IPC: B42B5/10
Filed: 1966-03-11
Abstract: 1,133,153. Bookbinding. CARTIERE PAOLO PIGNA, S.p.A. 11 March, 1966 [8 April 1965; 15 Feb., 1966], No. 10891/66. Heading B6A. Assemblies of perforated sheets are bound into book form by elements sold under the Registered Trade Mark "Wire-O", comprising hair-pin shaped prongs bent out of a straight wire at regular intervals along the length of the wire, by first causing the sheets to become impaled on the prongs of the elements with the latter in half-closed condition, and then completing the closing of the elements, the elements being brought into the impaling position by being conveyed thereto in the direction of their length. The closed binding element (12, Fig. 1) comprises a wire bent to form prongs (14) separated by aligned straight lengths (16) of wire, the prongs being passed through perforations (20) in the sheets of the assembly (10). As shown in Fig. 2, the binder element material 12 is stored on a drum 22 driven by a motor 24, and the free end passes through a known motor control means 30, and over a saddle 26 to a sprocket (28, Figs. 3-5) which is driven by a motor 36 and gearing (38). The binder material 12 is initially in unclosed condition, and is supported between the saddle 26 and the position where the prongs (14) engage assembly 10 of sheets, by a curved guide rod (32) which causes the binder material to hug the teeth on the sprocket (28). The sheet assemblies 10. are conveyed intermittently from right to left, Fig. 2, by pushers 44 on a pair of conveyer chains 42, and the leading edge of each assembly passes beneath a photo-cell device 46 which conditions the circuit of the sprocket motor (36). When the leading edge of the assembly 10 passes the cell 46, it is engaged by a feeler (48) which completes the circuit of the motor (36) and causes the binder material 12 to be drawn from the drum 22 for the period of time that the feeler engages the assembly 10. A cutter (60) on a further sprocket (58) driven from the shaft of the sprocket (28), severs a length of binder material 12 appropriate to the length of a sheet assembly 10, and further conveyance of the severed length is by means of an endless belt 64 which presses the binder 12 against a downwardly sloping continuation of the guide rod (32), and causes the prongs (14) to impale the perforations of the sheets. The binding edge of the assembly 10 then enters a tunnel (66, Figs. 6 and 9) having a helical rib (70) therein, which causes the binding element 12 to turn about its longitudinal axis to engage the sheet perforations fully (Fig. 9D). On emerging from the tunnel (66), the assembly moves into a press at station E, where a movable jaw (80, Fig. 9E) closes the binding element 12 into cylindrical form. This press is operated automatically when the pushers 44 on the chains 42 raise a contact (82, Fig. 10) to energize a solenoid (83) and cause a clutch (84, 86) to be engaged with a shaft (88) driven continuously by a motor 90, the shaft (88) being connected to the movable jaw (80).

Abstract: 512,750. Moulding sliding-clasp fasteners by injection. MORIN, L. H., and MABINSEY, D. March 4, 1938, Nos. 11196/39 and 11197/39. Convention dates, March 18, 1937 and July 10, 1937. Divided out of 512,714. [Class 87 (ii)] In forming fastener elements on a stringer tape 102 or other mounting member passing between relatively movable die parts, a cylinder 64 is charged with thermoplastic material, such as cellulose acetate, which is heated therein and intermittently injected therefrom into a mould cavity between the die parts, the cylinder being shifted into and out of register with a mould orifice and its discharge end being sealed by engagement with one of the die parts when in non-injecting position. In one form hopper73 and cylinder 64 are mounted on a frame 48 adapted to oscillate about pivots 49, 50 so as to move to and from the mould orifice. The plunger 70 is connected at 79 to the hopper feed-slide 78 and is operated by a bell-crank 71, rod 82, three-way crank 87 and cams 89 on a shaft 29, driven from a main shaft 24. The stroke of the plunger is adjusted by a nut 84 and spring 83. The dies are moved by rods 93, Fig. 1, operated from the shaft 29. The electric motor circuit is arranged to be cut off if there is differential action between the dies. In operation, the dies are moved together about the stringer tape 102 and a core-pin 141 is moved into position. The core-pin is carried by a slide 111 mounted on a rocker shaft 33 operated from the shaft 29. The frame 48 is urged against the dies by a spring 90 and is maintained in light engagement with a die surface when out of register with the mould orifice by a cam-operated lever 91. Grippers 116, 134 are provided to bold the tape during injection by the plunger 70. The grippers are operated from the cam shaft 29. After casting the dies and lower grippers 134 are opened and the core and upper grippers are moved down by the slide 111 so as to position the tape for casting the next fastener. The grippers 134 are closed again and the core and grippers move back to the initial position, the previous casting being stripped from the core. When the required number of fasteners are cast on the tape, a long quick feed of the tape is provided by a rotary segment 127 against which the tape is pressed by a roller 126 on a spring-pressed slide-bar 125 which is released for this purpose by a pawl 131 controlled by a trip chain 60 operated by sprocket and worm gearing from the main shaft. A finger 109 is moved upwardly between guide fingers 108 between each casting so as to kink the tape and provide sufficient slack. The tape is initially fed between a spring-pressed roller 104 and a recessed block 105 having a pin 106 which operates to cut off the electric motor when the supply of tape ceases. Specifications 431,209, 489,788, 512,714, 512,715 and 512,751 are referred to.
