Title: Improvements in and relating to gauges of ring and plug type
IPC: G01B3/46
Filed: 1945-10-22
Abstract: 603,510. Linear-dimension gauges. WILKINSON, E. Oct. 22, 1945, No. 27782. [Class 106 (ii)] A ring or plug gauge comprises a ring which is slotted substantially radially from its inner to its outer periphery and is reduced in crosssection at a single opposite point to the slot so as to be more flexible at this zone than elsewhere and adjustment means adapted to flex the said ring by contraction in the case of a ring gauge or by expansion in the case of a plug gauge, to take up wear or for adjustment. A ring gauge for screw threads, Fig. 1, includes an internally threaded ring 5, broken by a radial slot 6 and having an opposite slot 7 of keyhole form. The ring may be contracted by two grub screws 8 in a circular housing 9 having an internal flange 12 to receive a shoulder formed on the ring 5 which is held in the housing by means of a clamping plate 13 engaging a shoulder on the opposite side of the ring 5. A third screw 10 engages the slot 6. A screw-thread plug gauge, Fig. 3, includes a similar gauge ring 5 which is threaded externally and mounted on a holder 19, a locating pin 22 entering the slot 6 of the ring. A cone 17 engages a conical bore in the ring 5 and has a shank 18 provided with adjusting and locking nuts 20, 21 by means of which the cone may be drawn inwardly to expand the ring 5. Rotation of the shank 18 is prevented by means of a screw or key secured to the holder which projects into a slot in the shank. The housing 9 or holder 19 may be used with different gauge rings 5, which, when threaded, may have the central part of the thread undercut. The temper of the gauging rings 5 is preferably drawn slightly adjacent to the slot 7.

Title: Improvements in or relating to signalling or remote control systems
IPC: H04Q9/06
Filed: 1936-10-14
Abstract: 469,869. Electric signalling and remotecontrol systems. COMPAGNIE DES TELEPHONES THOMSON-HOUSTON. Oct. 14, 1936, Nos. 27951 and 27952. Convention dates, Oct. 19, 1935 and March 31, 1936. [Class 40 (i)] The direction of the first pulse of an alternating-current signal determines the signal or control effected. A time relay may also be provided to effect control only if a current persists for more than a predetermined time and several units may be operated over a single line by using different frequencies. When one of the keys 15<1>, 15, Fig. 1, is operated pulses of unidirectional current pass from the generator 5 to the transformer T. Alternating current thus flows through the relay 9, but the direction of the first pulse enabled one or other of the control relays 14, 13 to energize and to open the circuit of the other relay, the operated relay closing a shorting circuit for itself to enable it to hold during the oscillations of armature 10 of relay 9. The control relays may be connected directly across the transformer as shown in Fig. 2, the relay operated being determined by the current flow of the first pulse which is passed by rectifier 18 or 19. When one relay operates it opens the circuit of the other relay and connects its lower winding to the other rectifier, the windings being arranged so that the flux is in the same direction when either winding is energized through the appropriate rectifier. Circuits in which a slow-to-operate relay maintains the control circuit open until the control current has persisted for a predetermined time and in which glow-discharge tubes, known under the Registered Trade Mark " Thyratron" are used to determine the direction of the first pulse, are also described in the Specification.

Classes 83 (ii) and 83 (iii). [Also in Group XXIII] A cutting element for use in or as a file, rasp or cutting disc, similar to those described in Specifications 666,621 and 666,622, comprises a rigid bar or sheet of hardenable steel having through holes with cutting edges formed by upset portions of the edges of the holes, the edges having positive cutting clearance and rake angles relative to the general plane of the bar &c. and all facing in the same general direction, and the bar &c. being hardened. The bar may be surface-hardened, as described in Specification 695,821, or hardened throughout. The cutting edges may also have angles of shear as described in Specification 666,621. As the extent of upset of the cutting edges from the element surface is small, the surface itself limits the depth to which each edge may cut but the element may be reversely bent along the edges and between the rows to give rubbing surfaces as described in Specification 695,830. Specifications 267,563, [Class 61 (ii)], 488,925 and 638,474, [both in Group VI], also are referred to.

Title: Improvements in talking moving picture machines
IPC: G03B31/00
Filed: 1924-11-24
Abstract: 225,840. Forest, L. de. Dec. 7, 1923, [Convention date]. Optical apparatus.-An attachment to a kinematograph, which enables " talking moving pictures" to be reproduced comprises as its main feature a light slit and a " presser foot " device provided with yieldable pressure shoes, adapted to keep the film close against the slit when required, or to be pushed back and held away from the film when the machine is being used only for projecting pictures. The slit can be readily adjusted as to its width, is accessible without difficulty, and can be easily widened when cleaning is necessary. The apparatus shown (Fig. 2 being a plan seen from underneath), comprises a frame or casing 1 through orifices in the end wails of which extend respectively a photo-electric cell 15 and a case 11 containing a light source. Between the case 11 and the cell 15 are arranged a tube 12 fitting into a plate 20 secured to the side plate of the frame 1, an adjustable slit-member 30 mounted on the plate 20, and a pair of pressure shoes 65 yieldingly supported on a block or " pressure foot " 50 which is mounted in guides on the side wall of the frame 1. The pressers 65 serve to keep the soundrecord portion of the film against the slit as the film passes over rollers 16 and between plates 47, 48 fixed on either side of the slit plate 30. The slit proper 42 is formed between a bevelled edge 38 on the plate 30, Fig. 9, and a bevelled edge 41 on a smaller plate 39 slidably recessed into the plate 30. Adjustment of the slit is effected by means of a handle 26, mounted on a spindle 25 from the end of which projects a pin 27 engaging in a slot in the plate 39. After the necessary adjustment has been made, the spindle 25 is clamped by a set-screw. An air duct in the plate 20 connects a nozzle 24 to a chamber 22 in the plate 20 behind the slit 42, so that air can be blown through the slit to clean it when required. The block 50 carrying the pressure shoes 65 is removably held in the casing 1 by means of lugs 59, 60, engaging with flanges 61, 62 on the casing, a pawl controlled by a lever 75 serving to lock the block in the operative position. Fitting in a recess at the rear of the block is a sleeve 52, which is pressed bv a spring against the end wall 2 of the casing. The sleeve carries a pin projecting through an L-shaped slot in the block 50, and this enables the pressure-shoes to be held away from the film when desired, after the block has been pushed back and slightly turned. A hinged door 90 having a window therein is provided on the casing 1. Specification 214,938 is referred to.

Title: Improvements in or relating to apparatus for connecting an input member and an output member together for unitary rotation
IPC: F16D13/54
Filed: 1961-08-02
Abstract: 997,418. Friction Clutches; ratchet clutches. DANA CORPORATION. Aug. 2, 1961 [Aug. 9, 1960], No. 28106/61. Heading F2C. A self-tightening unidirectional or bidirectional multi-plate friction clutch comprises, as shown in Fig. 1, a unidirectional clutch having clutch plates 24, 26 mounted on a driving gearwheel 14 and on a member 28 which has internal helical teeth 58 meshing helical teeth on a sleeve 62 fast with a driven shaft 12. The member 28 is centred on the sleeve 62 by Belleville springs 64, 66 and is provided with cam grooves 40 receiving balls 42. The clutch is engaged by shifting a manually operated sleeve 44 to the right so that the balls 42 are cammed inwardly by a surface 50 and compress a Belleville spring 36 which acts on a clutch presser plate 30 to give light clutch engagement. If the gear 14 is rotating forwardly, the member 28 is screwed along the sleave 62 against the bias of spring 66 to fully engage the clutch. Reverse rotation of the gear 14 screws the member 28 to the left to disengage the clutch. As shown, two multiplate clutches having a common control sleeve 44 and a common member 28 having two sets of ball receiving pockets serve to selectively clutch the driven shaft to two gear-wheels for opposite directions of rotation. Fig; 2 shows a bidirectional clutch having plates 90 splined to a sleeve 88 which is splined to an input gear 80 and plates 86 splined to a driven gear 83 which is keyed to a driven shaft 78. Balls 99 are received in apertures 98 in the sleeve 88 and are cammed inwardly on shifting a manually operated control collar 101 to the left. The balls 99 act against a cam surface 97 of a presser plate 92 which is thereby shifted to the left to give initial clutch engagement. A reaction member 91 at the other end of the clutch plate pack is moved leftwards against the bias of a spring 95 until a surface 93 on the reaction member abuts a surface 94 on the driven gear during the initial engaging movement. The input gear 80 has helical teeth meshing helical teeth on a driving gear 81, and for one direction of rotation gear 80 is shifted to the left and acts through a spacer ring 103 to shift the presser plate 92 to the left to give full engagement. If the torque is reversed the input gear 80 is shifted to the right into engagement with a stop shoulder 107 on the driven shaft 78. As the gear 80 shifts its hub portion 104 engages a snap ring 105 mounted on the sleeve 88 and shifts the sleeve to the right, and a snap ring 96 on the sleeve acts through the spring 95 to shift the reaction member 91 to the right. Movement of the spacer ring 103 to the right is limited by a stop shoulder on the driven shaft 78 so that the initially applied engagement pressure of the clutch is increased.

Abstract: 1,020,639. Phase and frequency modulation. PHILCO CORPORATION. July 19, 1963 [July 19, 1962], No. 28666/63. Heading H3R. Modulation is applied to two or an even number of cascaded transistor (or valve) amplifiers having collector (or anode) circuits approximately resonant with the collector (or anode) circuit capacitance and each producing a variable phase-shift in the same direction of an applied carrier dependent on the modulation applied in like phase to a common electrode of the amplifiers, e.g. the emitters of transistors with common emitter configuration, to vary the collector circuit capacitance. Amplitude modulation is thereby avoided at the output. With an integrating network in the path of the modulation, frequency modulation is produced. Successive phase modulators in cascade may be used. The phase modulator may be part of an amplifier with output back-coupled to its input to form a frequency modulated oscillator. R-C circuits in the feed-back path between the collector circuit of one stage and the base of a following stage may limit the gain to prevent squegging.
