Title: Improvements in sliding vane fluid-operated rotary piston machines
IPC: F02B53/00
Filed: 1965-05-31
Abstract: 1,068,505. Rotary sliding vane machines. ATLAS COPCO A. B. May 31, 1965 [June 19, 1964], No. 23175/65. Heading F1F. To reduce the weight and manufacturing costs of the housing of a rotary sliding vane machine usable as a pneumatic or hydraulic pump or motor, the housing comprises a tubular member 13, Fig. 3, cut from accurately dimensioned tubular stock and formed in its softened conditioned with groups of radial slots 14, 15, 16 and a separate member 32 cut from rolled stock or formed from sheet material seam-welded along its flanges 33, 34 externally of the tubular member to form an axial passage 26 communicating with the group of slots 14. The assembly may then be tumbled to remove burrs and case-hardened to improve its wearing properties of the bore of the tubular member which is subsequently polished. A spring- loaded pin 21 housed in one casing end plate engages a recess in the end of the tubular member 13 to prevent rotation of the assembly in the casing 1. In a modification, a lug 35 may be spot welded externally at one end of the tubular member 13 to receive a further spring-loaded pin. Operating as a motor, the slots 14 communicate through the axial passage 26 and a port 25 in the other casing and plate with a supply of pressure fluid and the slots 15, 16 into an exhaust and silencing chamber 39. Modified to permit the motor to operate as a reversible motor a mirror image of the member 32 is also fitted to provide an axial passage communicating with the slots 15. The slots 16 are then conveniently replaced by exhaust ports located diametrically opposite to the lug 35. A separate member formed with an axial passage and completely surrounding the tubular member with a snug fit may be banded to the tubular member by a suitable adhesive.

Patent GB-1273086-A (GB)
Title: Device for the controlled actuation of the basket of a washing machine
IPC: H02P7/292
Filed: 1970-05-13
Abstract: 1,273,086. Rectifying. INDUSTRIE A. ZANUSSI S.p.A. 13 May, 1970 [17 May, 1969], No. 23267/70. Heading H2F. [Also in Division G3] A washing machine is driven by a D.C. motor 2 which is supplied through a constant-current transformer 18 and a bridge including controlled rectifiers 11, 12. When the speed of the motor is below a predetermined value, a transistor 48 is cut-off at the instants when the full-wave rectified voltage derived from a mains-supplied network 24-27 reaches zero, the transistor becoming conductive immediately after. A transistor 45 is rendered conductive each time the transistor 48 is cut-off, whereby rectifier 39 operates to trigger the rectifiers 11, 12. The motor thus receives a continuous train of halfwave pulses having twice the mains frequency and in phase with the mains voltage. A reference voltage is developed across a capacitor 40 and is compared with a signal representing the motor armature voltage derived from bridgeterminals 57, 61. If the speed exceeds a predetermined value set by selector switch 60, transistor 52 becomes less conductive and Zener diode 51 breaks down. Transistor 48 is then rendered continuously conductive to cutoff the transistor 45 and prevent energization of the motor until the speed is reduced to the desired value, entire half-waves of the motorcurrent being suppressed rather than portions thereof. Steep-fronted pulses, which cause R.F. noise, are thus avoided. The components 39, 45 may be replaced by a multivibrator and amplifier, and the motor speed may be sensed by a tachometer.

Filed: 1952-09-18
Abstract: 726,672. Vehicle wheels. FRIED, J. M. April 7, 1953 [Sept. 18, 1952], No. 23446/52. Class 144 (2). In a detachable-flange wheel with the detachable flange D movable transversely of the wheel rim A into, and secured in, operative position by rotary movement of a ring-like clamping member C having a screw threaded or other rotary engagement with the wheel rim the arrangement is such that removal of the ring-like clamping member C is not necessary for detachment of the flange D and that only transverse movement of the detachable flange can occur, there being interfitting projections G and recesses on the detachable flange and wheel rim to ensure only such movement. For example the ring-like clamping member C may have threads of opposite hand engaging with corresponding threads on the under surfaces of the wheel rim and of the detachable flange. Or, as shown in Figs. 1 and 2a, the ring- like clamping member C rotatably held on the wheel rim may have upstanding castellations E with helical faces to act upon corresponding downward helically faced castellations F on the detachable flange D after the castellations of the detachable flange have been inserted axially through the gaps between the castellations of the ring-like clamping member with subsequent rotation of the ring-like clamping member. The rotational turning of the ring-like clamp member may be effected by a pinion and rack device.

Title: Method of and apparatus for drawing sheet glass
IPC: C03B15/18
Filed: 1925-09-23
Abstract: 247,862. Golby, F. W., (Libbey-Owens Sheet Glass Co.). Sept. 23, 1925. Drawing.-Relates to sheet-drawing apparatus of the Colburn type, as described in Specification 114,977, and consists in applying drawing-forces to the sheet edges at a series of spaced points and at successively greater drawing-speeds as the sheet is drawn away from its source. The sheet 1 is drawn upwards from a mass of glass 2 towards a bending-roll 4, and each of its edges is gripped near its source by a pair of rollers 7. These rollers are driven at a slower peripheral speed than the speed of the sheet in order to maintain the width of the sheet. In accordance with the invention, a second pair of rollers, 9, is arranged to grip each edge of the sheet at a point between the first pair and the bending-roll, and they are driven at a peripheral speed between that of the first pair, 7, and that of the bending- roll. Due to the additional stretching-force applied by the rolls 9, the narrowing of the sheet which usually takes place between the rolls 7 and the bending-roll, and also the tendency to form surface inequalities, is reduced. The rollers 7, 9 need not be cylindrical but may be shaped to form a thicker edge or bead on the sheet.

Abstract: 1,098,574. Electromagnetic brakes. LAMBERT BRAKE CORPORATION. June 3, 1965 [June 4, 1964], No. 23757/65. Heading F2E. An electromagnetic disc brake of the kind in which energization of a winding 78 causes the engagement of primary friction surfaces provided by a lining 86 on the magnet with one face of a rotor 36 or of a disc 88 secured thereto, resulting in rotation of a ring 62 which by the camming action of balls 72 causes engagement of the main friction surfaces provided by rotor discs 34, 36 and stator disc 38 and casing 24, includes a force-multiplying arrangement between the magnet ring 80 and the ring 62 consisting of a pair of levers 98, 100 which are pivoted on a stator or driven plate 20 by pins 102, 104 and which pivotally engage at one of their ends, by pins 90, 92, the magnet ring 80, and at their other ends, by pins 110, 112, engage pivotally the ring 62. In operation, the engagement of the primary friction surfaces upon energization of the magnet winding causes rotation of the magnet ring which, via the levers 98, 100, rotates the ring 62 to a less extent but with greater force, this force being then further multiplied by the action of the balls 72 to give a self-servo effect. Springs (74) (Fig. 2, not shown) acting between the ring 62 and the plate 20 overcome the servo effect on release of the magnet to release the brake. Disc 38 is guided by slotted ears 58, 60 on splines of the casing 24 so as to rotate with the latter but allow relative axial movement. Discs 34, 36, which are provided on both faces with linings, are guided for axial movement on a hub 14 by pins (52) (Figs. 1 and 2, not shown). The assembly is located within a vehicle wheel 12 and secured to studs carried by the wheel hub.

Title: An improved process and apparatus for coking coal
IPC: C10B47/00
Filed: 1920-08-21
Abstract: 175,319. Roberts, A. Aug. 21, 1920. Drawings to Specification. Coking processes; retorts.-A process for coking coal consists in introducing heat into the mass of the coal so rapidly that the temperature is raised high enough to effect the decomposition of the resinous content of the coal (660‹-750‹ C.) before excessive oxidation or distillation of such content occurs, whereby a cementing or binding material necessary for the production of metallurgical coke is formed. A suitable retort for carrying out this process has a relatively large mass compared to the mass of the charge. and a relatively la.rge area for the transmission of heat to the charge and for absorbing heat from the heating-flues. The retort may have a relatively narrow charge-containing space and may be, in consequence, extended in length.

Abstract: 1,016,932. Fluid-pressure servomotor systems. ROBERTSHAW CONTROLS CO. June 19, 1963 [Aug. 17, 1962], No. 24455/63. Heading G3P A pneumatic force balance device for producing an output pressure as a function of a number of input pressures comprises a pair of balance levers 60, 62, Figs. 2 and 6 (not shown), acted upon by four flexible diaphragms 98 and having fulcrum points constituted by rollers 63, 66 on a carriage 68 which is movable by a spring-loaded diaphragm motor 34 in response to changes of pressure in a chamber 52 connected by a port 124 with a valve member 126 movable by the lever 60 relatively to a nozzle (not shown). Further rollers 76, 78 on the carriage engage tracks on a plate 72 but do not engage the levers 60, 62, whilst the fulcrum rollers 64, 66 do not make contact with the plate 72. The diaphragms 98, which are free portions of a single flexible sheet clamped between apertured plates 94, 100 have button assemblies at their centres with pins 108, 110 engaging the levers, and three of the diaphragms, which have loading springs 142, define chambers A, B, D which have inlets 90 for input pressures. The fourth diaphragm, loaded by an adjustable leaf spring 150, defines a chamber C in which the output pressure is established. In operation, any change in pressure in the chamber A or B will result in actuation of the valve member 126 to cause the diaphragm motor 34 to move until the fulcrum roller 64 is positioned such that the lever 60 is rebalanced. The accompanying movement of the roller 66 will throw the lever 62 out of balance so that the pressure in chamber C is altered, by lifting a valve member 144 from a seat in a partition 146 to admit pressure from a supply port PM or by lifting a seat 148 away from-the valve member to open an exhaust E to atmosphere, whereby the lever 62 is brought back into balance. The output pressure C will be a function of the product of the input pressures A, D divided by the input pressure B. If the pressure B. If the pressure D is maintained equal to the pressure A and the pressure B is constant the output pressure will be proportional to the square of A, and if B is maintained equal to C and D is a constant the output pressure will be proportional to the square root of A. The surfaces of the levers 60, 62 engaged by the rollers 64, 66 may be curved to give non-linear action. In a modification, the diaphragm motor 34 moves only the fulcrum roller for the lever 60, that for the lever 62 being adjusted by a second diaphragm motor controlled by a valve influenced by the position of the motor 34 through its loading spring 54.
