Title: Improvements in or relating to a chuck control mechanism for a tool
IPC: A61C1/14
Filed: 1968-12-17
Abstract: 1,242,077. Dental handpieces. ATLAS COPCO A.B. 17 Dec., 1968 [29 Dec., 1967], No. 59863/68. Heading A5R. [Also in Division B3] A chuck control mechanism for dental or other tools comprises a tubular housing 1 with a drive shaft 6 and a chuck 15 for gripping the shank of a tool (not shown) mounted therein, a tubular carrier member 14 axially movable and rotatably mounted over a portion of said shaft, with a frustro-conical surface 20 engaged by a corresponding surface 17 on the chuck, and an axially fixed control ring member 42 rotatably mounted on the outside of the housing and acting on an axially displaceable ring segment 35 which engages with the tubular member 14 so that rotation of the ring in one direction tightens the grip of the chuck, and in the other direction disengages it. The chuck 15 consists of a sleeve with slots (19), Fig. 3 (not shown) extending parallel to the axis from both ends, and has tapered ends, 17, 18, and 18 engaging a tapered surface 12 in a sleeve portion 11 of the shaft 6. A spring 24 acts between a shoulder 13 of the shaft 6 and a bushing 21 which is fixed on the member 14 so that the surface 12 is pressed towards the surface 20, and the tapered surfaces 17, 18 of the chuck are subjected to a pressure which results in a gripping action on the shank of a tool in the chuck bore. The carrier member 14 is rotatably mounted in ball bearings 8, 9, the outer races of which are fitted in a tube 33 which is a sliding fit in a bore 32 of the tubular housing 1. Ring segment 35 is provided with screw threads 40 cooperating with threads 41 on the inside of the ring 42. Alternatively, camming means may be provided, to move the ring segment parallel to the housing axis to engage with a shoulder 45 on the carrier member 14 to brake its rotation and then relieve the chuck 15 of axial pressure from spring 24, whence the shank of the tool may be pulled out of the bore 16 of the chuck. Shaft 6 is rotatably mounted in the tubular housing 1, partly directly in a ball bearing (7), Fig. 1a (not shown) and partly indirectly in ball bearings 8 and 9. A plurality of ring segments 35 may be provided.

Title: Spindle driving mechanism
Inventor: PAGET ARTHUR AVERIL
IPC: D02G1/06
Filed: 1969-12-08
Abstract: 1298469 Friction gearing SCRIVEN & PAGET Ltd 4 Dec 1970 [8 Dec 1969] 59866/69 Heading F2Q [Also in Division D1] Means for driving a pair of spindles 3, 4 adapted to run at speeds of the order of 600,000 r.p.m., e.g. tubular spindles used in false-twist yarn crimping machines, comprises two coplanar driving and support wheels 1, 2 either or both of which may be power driven, and two horseshoe magnets 35, 36 with polepieces 38, 37 so shaped and located that each spindle is attracted more strongly into contact with the wheel by which it is supported than the wheel by which it is driven. Thus, with the wheels rotating anticlockwise, the spindle 4 is driven by the wheel 2 and supported by the wheel 1 and the magnet 36 attracts it in the direction 9, whilst the spindle 3 is driven by the wheel 1 and attracted by the magnet 35 in the direction 10 towards its support wheel 2. Each spindle 3, 4 is restrained against endwise movement by a flange coacting with peripheral grooves in the wheels 1, 2 or by a pair of flanges spaced to straddle the thickness of the wheels. The wheels have facings of tough, rubber-like synthetic material for frictional engagement with the spindles and are mounted on shafts 24 carried in eccentrically mounted bearings for adjustment purposes. The shafts may be driven by electric motor or have pulleys &c. by which they may be driven when brought into contact with a moving belt.

Abstract: 1,273,710. Change-speed control. FORD MOTOR CO. Ltd. 22 Dec., 1970 [8 Jan., 1970], No. 60765/70. Heading F2D. The slide-turn movement of a tube 20, surrounding a short vehicle steer-shaft 10, and under control of a shift lever 26 controlling, e.g. a manual transmission, is transmitted through a pin-and-slot connection 62 between arms 44, 60, to a second slide-turn hollow shaft 52, parallel to the steer column and having a clutch pin 96 selectively engageable with clutchelements secured to arms 92, 94 linked respectively to first-reverse and second-high shift arms on the transmission. A spring 50 at the bottom of the column biases to second-high channel 94. The tube 52 slides on a bearing 54 attached to a fixed bracket by a ball-ended stud 58, which accommodates misalignment. A spring 72 biases the tube 52 away from the bracket 40. The movement transmitting pin 62 passes through a releasable insulator bushing 66 which becomes detached by impact load on the steer column.

Title: Animated figures
IPC: A63H13/00
Filed: 1978-12-20
Abstract: Realistic life-like movement of the mouth 28,30 and other parts of animated figures, toys, puppets etc. is achieved by replacing the conventional solenoid of the animation control mechanism by a coil (16) movable in a magnetic field. One thereby obtains a linear instead of a logarithmic response. The movement of the coil (16) is preferably in response to changes in the amplitude of the envelope of the volume component of a voice signal. An intercom system comprising two units each having a loudspeaker/microphone, a mouthpiece and a mouth control mechanism can be wired up so that voice signals can be transmitted from one unit to the other and vice versa with accompanying movement of the respective mouthpieces. <IMAGE>

Title: Antigen from Streptococcus Mutans for Protection Against Dental Caries
IPC: A61K39/09
Filed: 1979-08-22
Abstract: An antigenic protein, termed antigen A, obtained from cultures of Streptococcus mutans, especially genetic group I (serotypes c, e and f) is separated from other antigenic proteins, notably those which cross- react with heart tissue, to give an antigenic preparation which may be used as a vaccine or to raise antibodies for use in protecting against dental caries. Antigen A has a molecular weight of about 29,000, and an isoelectric point of 4.1 to 4.5. Its amino-acid analysis is also given. The antigen may be obtained from the culture filtrate and/or cell extract and may be readily purified from these sources by, for example fractional ammonium sulphate precipitation and/or affinity chromatography on immobilised antibody. The antigen may be formulated into a vaccine with an injectable carrier and optionally an adjuvant (e.g. aluminium hydroxide), or alternatively may be injected into animals to raise antibodies which may be formulated with a pharmaceutical carrier into preparations for administration by injection or by swallowing, or for topical oral application (e.g. toothpastes and mouthwashes) for protection against dental caries.

Title: Butterfly valve
IPC: F16K1/226
Filed: 1979-10-22
Abstract: A butterfly valve member 4 pivotally mounted in a valve casing providing a valve seat has a peripheral sealing ring 6, for engagement with the valve seat, ring 6 being located in an annular groove 7 around the valve member. The sealing ring 6, in axial section, has the form of a 'U' with the base of the 'U' radially outermost and the limbs of the 'U' extending from the base of the 'U' towards the axis of the ring. An incompressible support ring 10 is disposed within the ring 6 between the parts providing the arms of the 'U'. In use the parts of the ring 6 providing the arms of the 'U' normally bear sealingly on the side walls of the groove 7 or on seals provided on these side walls but can be deflected resiliently whereby, in the closed position of the valve, the chamber defined between the ring 6 and groove 7 can be filled with the pressurised fluid upstream of the valve member and the ring 6 thereby expanded resiliently radially outwardly into more effective sealing engagement with the surface 5 of the valve seat formed in the valve casing. <IMAGE>
