Title: Synchronous motor
IPC: H02K21/14
Filed: 1967-02-20
Abstract: 1,116,293. A.C. motors; motor driving arrangements. MALLORY TIMERS Ltd. 20 Feb., 1967 [23 Feb., 1966], No. 7942/67. Heading H2A. A synchronous motor comprises a pair of housing shells each having a plurality of radially-shaped polepieces lanced out therefrom and extending axially inwards to interdigitate, forming a circle of stator poles; a field coil annularly disposed between the stator poles and the housing walls; a permanent-magnet rotor having peripheral salient poles and mounted so as to provide a uniform air gap; means for ensuring one-way rotation of the rotor including a member fixed to the rotor and a restraining member fixed to the housing; and a speed-reduction means, entirely disposed within the area circumscribed by the field coil, for coupling the rotor to an output shaft. As shown, stator poles bent inwards from each housing shell 10, 11, Fig. 5, are interdigitated and formed so that one narrow pole is followed by two broad poles sequentially around the pole ring to ensure starting. Field coil 12 is disposed betweeen this pole ring and the external wall of the housing. The rotor consists of an axially-polarized permanent magnet disc covered by end plates providing interdigitated poles 14, 15. It has extending through it at one side a shaft 17 on which a pinion 21 is freely rotatable. As the rotor rotates, pinion 21 is driven around a gear 34 secured to housing plate 11 and a gear 35 secured to output shaft 36 to rotate the latter. Gear 35 has one tooth more or less than gear 34 to provide the necessary speed reduction. Rotating with the rotor is a disc 16 with a raised edge and radial ribs 22, 24 which co-operate with a Z-shaped piece of wire 33 secured at its centre in a fixed bushing 29. The ends of the wire are turned down so that when the rotor rotates from right to left (as viewed in the drawing) the ribs may pass under the wire ends, but in the opposite direction the ribs abut against the wire ends to stop the rotor. Fig. 12 shows an alternative oneway device where ramps 69, 71 on member 68 mounted on the rotor raise magnetic balls 73 into holes 74 in a fixed non-magnetic member 72 on rotation from right to left (arrow 76); rotation in the opposite direction is prevented by trapping of the balls (held down by magnetic attraction by the rotor) between the vertical ramp portions and the sides of the holes. In an alternative gear device a pinion is mounted on an eccentric shaft, secured to the underside of disc 16 and extending below the rotor; the pinion rotates inside two internallytoothed gears which perform the functions of gears 34 and 35.

Title: By-level broaching machine
IPC: B23D37/06
Filed: 1957-03-11
Abstract: 811,253. Broaching. LAPOINTE MACHINE TOOL CO. Ltd. [Lapointe Machine Tool Co.). March 11, 1957, No. 7967/57. Class 83 (3). A broaching-machine comprises two broaches A, B mounted in a holder to cut on opposite strokes, and alternately brought into operative position by relative transverse movement of the broach-holder and a work-holder 22. The broach-slide 12 is reciprocated mechanically or hydraulically. The work W is mounted on a stud 16 on a holder 20 angularly adjustable on a slide 22 movable vertically by a fluid-operated piston between stops 34, 35. The work is clamped by a fluid-operated device 55 acting through a wedge 50 and a bar carrying a clamping head 42. In operation, a switch is closed to clamp the work W. Downward movement of the wedge 50 operates a switch to start a motor for traversing the slide 12 through rack-and-pinion gearing. The slide 12 moves to the left and the broach A takes a roughing-cut. At the end of its movement, the slide actuates a switch to release the clamp 42. As the wedge 50 moves upwardly it actuates a switch to lower the slide 22. At its lower position, the slide 22 actuates a switch to return the slide 12 so that the broach B takes a finishing cut. During the latter cut, the clamp is not engaged, as the cutting force holds the work steady. At the end of the cut, the slide 12 actuates a switch to raise the slide 22 and to cause the work to be indexed by a solenoidoperated pawl-and-ratchet device. The clamp 42 is also re-engaged and the cycle continues until a switch is automatically operated to stop the machine.

Title: Process for the production of fibre-coated sheet formations of high pile density
IPC: D04H11/00
Filed: 1964-02-26
Abstract: 1,057,276. Flock-fibre coating. FARBENFABRIKEN BAYER A. G. Feb. 26, 1964 [March 2, 1963], No. 8042/64. Heading B2E. Fibre-coated sheet material having a high pile density is made by introducing short fibres endwise into an adhesive layer applied to the upper surface of a backing sheet by means of an electrostatic field, so that excess short fibres remain on and between the short fibres anchored in the adhesive, the fibre-coated sheet then being guided over rotating polygonal rods. The fibre-coated sheet, when guided over the rotating polygonal rods may be subjected to an electrostatic field weaker in intensity than that used for the initial deposition of fibres. As shown backing cloth 1 with adhesive layer 2 is passed through fibre-coating zone A and vibration zone B. Short fibres 3 are introduced into the adhesive layer using an electrostatic field created across electrodes 4 and 4'. Rotating polygonal rods 7 cause vibration of the fibre-coated fabric thus permitting, with the aid of the electrostatic field across electrodes 8 and 8', excess fibres to anchor in the adhesive layer.

Title: Improvements in machines for generating the teeth of gear wheels
IPC: B23F5/12
Filed: 1922-03-22
Abstract: 199,462. Soc. Anon. des Anciens Etablissements Hotchkiss et Cie, and Taylor, H. E. March 22, 1922. Gear-cutting.-Gears are generated according to the " tangent, rack " system wherein instead of the usual linear rack, the basic form is a crown wheel whose teeth are involute curves in a plane normal to the wheel axis. The normal pitch thickness of tooth. and space is constant thus permitting the generating of two adjacent tooth faces by means of a single tool whose cutting plane is maintained normal to the sides of the teeth. The wheel blank is mounted and actuated so as to roll as though in engagement with the basic crown wheel while the tool traces out a curved path corresponding to one tooth of the crown wheel, the tool path being derived from an angular movement about the imaginary crown wheel axis combined with a movement tangential to a circle of adjustable radius. In this manner the cutting plane of the tool is kept normal to the sides of the teeth which it generates. The blank A is mounted on an arbor B in a work head C which is movable about the axis 0-0 of the imaginary basic crown gear, the angle X being adjustable according to the gear to be cut. The motion about the axis 0-0 is derived from worm and sector gearing C<3> driven through change gears, shaft E and bevel gearing operated by ratchet and pawl mechanism from a shaft G which is oscillated by means of a cam 0 from the main shaft N. The shaft E is operatively connected to the gear blank arbor through bevel gearing, telescopic shaft H<3> and worm gearing, this movement together with the movement about the axis 0-0 producing correct rolling of the blank. The rack-tooth tool K is mounted on a slide J<2> carried by an oscillating member J on a shaft L oscillated by means of a rack M which is reciprocated by a crank from the main shaft. A rack J<3> on the tool slide engages a pinion J<4> connected to a pinion J<6> fixed to the member J so that as the latter oscillates the slide J<2> is reciprocated to impart the required curved path to the tool as shown in Fig. 4. In order to withdraw the tool from the work on the return stroke the bearings of the shaft L are mounted in a headstock L<3> engaged by a quick pitch screw P actuated by a cam P<4> and lever P<2> to withdraw the headstock on the return stroke along guides D<@>. For cutting wheels whose axes do not intersect the axis of the imaginary crown gear a cross slide may be provided for laterally displacing the respective axes about which the head C and member J move. Specification 199,463 is referred to.
