Title: Improvements relating to gear cutting machines
IPC: B23F9/10
Filed: 1961-12-14
Abstract: 929,164. Gear-cutting. GLEASON WORKS. Dec. 14, 1961 [Feb. 6, 1961], No. 44882/61. Class 83 (3). A machine for cutting spiral bevel or hypoid gears with a face mill cutter comprises a frame 10 having heads 11, 12 carrying rotary spindles 13, 16 for the gear G and tool C mounted for separate rectilinear horizontal adjustment, the work-spindle being inclined to the horizontal with the workpiece mounting at its upper end and the spindle lying in a vertical plane extending in the horizontal direction, the work-head being adjustable in a vertical plane perpendicular to the work-spindle, the cutter-head being adjustable about an axis 29 in a vertical plane and perpendicular to the work axis 14, the cutter head also being adjustable parallel to the work axis, and the axis 17 of the cutterspindle being perpendicular to the axis about which the cutter-head is adjustable. The cutter may be as described in Specification 884,741. The head 11 is adjustable on guides 18 on a slide 19 adjustable on guides 21 on a plate 22 by a piston-and-cylinder 23, 26 to move the work from a loading position G<SP>1</SP> to a cutting position. The plate 22 is adjustable transversely for cutting right- or left-hand spirals. The head 12 is adjustable on circular ways 28 on a slide 30 adjustable on guides 31 on a column 32 adjustable transversely on ways 33. The slide 19 is clamped by hydraulic means 34 during cutting, the only movements being axial and rotational movement of the cutter and indexing of the gear. The spindle 16 is moved by a cam 39 acting through a lever 42 having an adjustable bearing point 43 on a plate 45 on a block 36. The block 36 carries the rear bearings 37 for the spindle and is urged rearwardly by springs 38. The cam 39 is carried on a slide 47 which is urged forwardly by an hydraulic piston against an adjustable stop 54. In operation, when hydraulic pressure is released, the springs 38 withdraw the cutter spindle and the cam slide, and subsequently the work-slide is withdrawn. The cam slide 47 is clamped during cutting by hydraulic means 62. The machine may finish-cut gears in which case the cutter makes, say, ten axial reciprocations during a revolution to cut a tooth-gap, or may rough-out gears, in which case the cutter makes several revolutions to cut a tooth-gap.

Abstract: 991,689. Brushes for dynamo-electric machines. STACKPOLE CARBON CO. Nov. 19, 1963 [Dec. 18, 1962], No. 45636/63. Heading H2A. An electrical brush assembly adapted to be slidably mounted in a brush-holder 1 comprises a pair of thin carbon half-sections 7, 8, the outer portions of which are provided with a pair of opposing notches which together form a socket having side walls 13 converging towards the inner end walls 12 diverging towards the inner end, and a wedge 14 in the socket engaging the side and end walls and being pushed towards the inner end so as to force the sections 7, 8 apart. In Fig. 1, 3 the brushes 7, 8 are urged into position by a spiral spring 4 having an insulated portion 5 which bears upon the wedge 14, which is of rubber. The leads 9 from the two halfsections are joined at a common terminal 10. In Fig. 5, not shown, the wedge has a longitudinally extending ear which loosely encloses one of the wires of the lead 9, so that the wedge is not misplaced in transit.

Title: Improvements in disc brakes
IPC: F16D55/224

Abstract: 946,509. Disc brakes. D.B.A. S.A. Dec. 21, 1961 [Jan. 2, 1961], No. 45902/61. Heading F2E. A disc brake comprises a floating housing 12 extending across the inner periphery of an annular, peripherally driven, disc 2 and supporting pads 46, 48, the housing being slidable along and pivotable about an axle 36 carried by a fixed support so as to extend parallel to the axis of the disc, pivotal movement of the housing in one direction being prevented by engagement of the pads with abutment surfaces 9, 11 of the fixed support, and pivotal movement in the other direction being restrained by the engagement of a resilient buffer 52 inserted in a recess in the housing with another surface of the support. The housing incorporates an hydraulic cylinder 14 containing a piston 18 which has a reduced portion 22, seal 24 and dirt-excluding gland 20. The portion 22 carries a boss 44 which is received in an aperture in the backing plate of pad 48. A similar boss 42 is secured to the housing to be received in an aperture in the backing plate of pad 46. A spring 32 normally acts as a fixed abutment for the releasing movement of the piston but can be compressed in order to allow the pads to be inserted. A friction-type automatic clearance adjuster as described in Specification 938,976 is also provided in a backplate 26 of the cylinder which is provided with a seal 30 and is located against a shoulder of the cylinder bore by a stop ring 28. The housing is mounted on the axle 36 by providing an oversize hole 34 in a lug of the housing, the opening being shaped as shown, Fig. 3, and the assembly being sealed by a gland 38 which is packed with grease. In a modification, Fig. 5, alternative hand actuation with automatic adjustment of pad clearance is provided, comprising a cable connected to a lever causing rotation of a coarse pitch screw 66 which engages one pad 148 and threadedly engages a corresponding helical groove in a sleeve 68 which is screw-threaded into a lug 70 of the housing 12. The sleeve 68 has axial slots 72 so that when the brake is applied the sleeve expands radially and is thereby locked against rotation. A pawl 76 carried by the screw passes freely over the teeth of a ratchet wheel 74 carried by the sleeve when the brake is applied but is able to engage the teeth on release of the brake so that if wear has taken place sufficiently for it to have slipped over a tooth on brake application it rotates the sleeve upon release of the brake to reduce the pad clearance.

As shown the coil 28 is incorporated in the base circuit of a transistor 131 which controls a second transistor 58 having a resistor in its collector circuit. Output is derived from terminal 56 which may be connected by long leads or to the analyser circuit. In operation, with no signal induced in the coil 28 current flows through resistors 63, 57, 53, 52, to make transistor 131 conductive, but transistor 58 is non-conductive. When the potential across the coil 28 varies sinusoidally the transistor 58 is switched between conductive and non-conductive states to provide a rectangular output. In a modification (Fig. 6, not shown) the coil 28 is incorporated in a series circuit of resistors across the D.C. supply and the potential across it is applied to the base of a first transistor through a capacitor.
