Abstract: 1,267,922. Diaphragm pumps. DISTILLERS CO. (CARBON DIOXIDE) Ltd. May 30, 1969 [May 31, 1968], No. 26097/68. Heading F1A. [Also in Division A4] In a liquid dispense system, carbon dioxide at 27 pressurizes beer in tank 12 and pipe 13 up to combined reed switch and closed valve 14. On depressing one switch button 32 or 33, relays are energized to open a solenoid dispenser valve 30 or 31, close an exhaust valve 10 and open a solenoid valve 8 whereby air-pressure acts on diaphragm pump 5 to displace and dispense a predetermined volume of beer via pipes 15, 18 and check valve 17. When the diaphragm stops, reed switch/valve 14 opens to de-energize relay, closing valve 8 and the operated dispense valve 30 or 31 and opening exhaust valve 10 whereby pressurized beer at 12, 13 passes valve 14 and refils the diaphragm chamber via 15 for dispensing the next volume via either dispense point. On depressing one dispense switch e.g. 32, a relay renders the other 33 inoperative.

Abstract: 1345468 Multi-disc brakes; fluid friction braking; friction clutches ADOLF-SAURER AG 7 June 1972 [7 June 1971] 26575/72 Headings F2E F2F and F2C A device for the frictional interconnection of two relating rotatable members, i.e. a brake, a clutch, or a clutch-brake combination, comprises a plurality of substantially parallel coaxial discs 5, 23 connected non-rotatably and in alternation to the respective members and displaceable axially to effect engagement and disengagement of axially adjacent discs relative to each other, the discs 5, 23 having openings 7, 25 therethrough which at least partly overlap in certain relative angular positions of said members to form passages extending through the assembly of discs for the passage of a working fluid.  In the embodiment illustrated the device is a multi-disc brake for braking a rotor shaft 2 relative to a stator 1. The discs 5 are stator discs of tempered steel and guided for axial displacement on bolts 6 secured to a stator housing 3, the discs 23 are rotor discs of tempered steel and guided on bolts 24 secured to the shaft 2. The discs 5, 23 are brought into engagement by fluid actuation of pistons 9 arranged in cylinders 8 around the circumference of stator housing 3 and interconnected by a distribution line 10; the pistons act on a circular plate 14 guided by bolts 6. The working fluid acts as a hydrodynamic braking agent by virture of the internal friction generated in the working fluid as it passes between the discs 5, 23 and also acts as a cooling agent for the surfaces of the brake discs 5, 23 heated by dry friction. The working fluid is fed into the housing 3 from a pump or other pressure source through a supply line 17 and a distribution line 18 feeds bores 15 and a slot arrangement 16 in the plate 14 whereby the fluid reaches the discs 5, 23. A pump impeller 26 carried by the shaft 2 is arranged opposite a collecting pipe 20 in the stator housing 3, from whence it is fed to a discharge pipe 19 and thence through a cooling system to a reservoir. The openings 7 in all the discs 5 are axially aligned as are all the openings 25; these openings 7, 25 which act as they move relative to one another to assist the hydrodynamic braking are arranged on each disc with their centres on two series 28, 29 of parallel lines, the lines of one series forming an angle of 60 degrees with the lines of the other series; the centres of any three adjacent openings form an equilateral triangle whose side length is equal to or less than twice the diameter of the openings. After braking the discs 5, 23 are moved apart by spring units. When used as a clutch discs 5 are connected to a drive shaft. Coupling is hydrodynamic, hydromechanical or mechanical. When used as a clutch-brake combination a disengageable locking mechanism is provided for the stator.

Title: Improvements in and relating to rotor winding for asynchronous motors without starters
IPC: H02P1/26
Filed: 1922-10-02
Abstract: 204,532. Shenfer, C. Oct. 2, 1922. Alternating-current induction machines.-In a polyphase induction motor for starting without the use of a starting-device, each phase winding of the rotor is divided into two approximately equal parts which at starting are so connected that the two parts of one phase oppose one another magnetically and act as an ohmic resistance in a path through which current is caused to flow by an e.m.f. generated in a part of another phase. Corresponding conductors of the two opposing parts of a phase are placed in the same slots. Fig. 1 shows windings for a 3-phase rotor, each limb of which comprises two parts 1, 1<1>, 2, 2<1>, 3, 3<1>, the extremities of the parts 1<1>, 2<1>, 3<1> being connected to the mid-points a, b, c of the other parts 1, 2, 3. The two parts, such as 3, 3<1>, neutralize one another so that in the circuit o, a, 3, 3<1> the parts 3, 3<1> act as a pure resistance to the volts generated in the part o, a. By moving the points a, b, c towards or from the point o smaller or larger starting currents may be obtained. Transition to the running condition may be made by short-circuiting, step by step, portions of the windings so that the neutralization between the two parts is gradually removed, as shown in Fig. 2. The parts 1, 2, 3 are provided with contacts a0, a, a<1>, a<11>, b0, b - - c0, c - - which are successively closed in the order a0, b0, c0, - - a<11>, b<11>, c<11>, producing the equivalent of a polyphase winding having short-circuiting connections between corresponding points of the phases. In the case of small motors, where the starting current rush is not great, the half phases may be directly short-circuited at a<11>, b<11>, c<11>. In an alternative form, the inner ends of the parts 1<1>, 2<1>, 3<1> are connected to the mid-points of the parts 2<1>, 3<1>, 1<1> respectively instead of 2, 3, 1 as shown in Figs. 1 and 2.

Abstract: 741,344. Drilling. MERCER, A. C. Sept. 29, 1953, No. 26682/53. Class 83 (3). A system for controlling the feeding speed of a drill &c. 9 comprises fluid pressure means 5 for moving the drill, the means being controlled by an electrically-operated valve 12 in a circuit which includes a contactor 19 movable in unison with the drill over a series of contacts 22. In operation, a switch 14 is closed manually to advance a valve 3 to admit air under pressure to a piston 5 and to close contacts 24. The piston 5 forces fluid at an increased pressure against a piston 8 carrying the drill 9. The piston 8 carries with it a switch-operating arm 18 and the contactor 19. As the contactor passes off an insulating strip 21 on to one of the contacts 22, a solenoid 23 is actuated to close the valve 12. Fluid then passes through an adjustable orifice 11 to move the drill at a lower feeding speed. When the drill reaches the end of its travel, the arm 18, after a delay, actuates a switch 17 to release the solenoid 15 and open the exhaust line 2. At the end of the fast return stroke the arm 18, after a delay to allow possible indexing of the work, actuates the switch 16 to repeat the cycle.
