Patent GB-1169984-A (GB)
Title: Improvements relating to Dynamo Electric Machines
Inventor: BATES JAMES JOHN
IPC: H01R39/64
Filed: 1967-01-25
Abstract: 1,169,984. Commutation arrangements for dynamo-electric machines. NATIONAL RESEARCH DEVELOPMENT CORP. 24 Jan., 1968 [25 Jan., 1967], No. 3845/67. Heading H2A. A commutated dynamo-electric machine has rolling contact brushes backed up by a contact breaking device, e.g. a thyristor, which ensures that the brush-current is zero as it leaves the segment. This principle is especially suitable to machines of inverted construction in which the commutated winding rotates around a fixed field member. A commutating arrangement suitable for such machines consists of two pairs of contact wheels 14, 16 and 18, 19 carried on conducting spindles 14, 15 in a cross-piece 11. These wheels make contact with the inner surfaces of slip-ring 20 and commutator 21 connected to the stator winding. Preferably, there are few commutator segments. Preferably also, two commutators are used with successive winding tappings being taken to alternate commutators, each tapping being connected to opposite points on the same commutator to give parallel paths (Figs. 4-7, not shown). The extinction voltage for the thyristor may be derived from interpoles on the stator. In machines of conventional layout, the contact wheels roll on the outer periphery of commutator drums. The axles of the brush-wheels serve as slip-ring surfaces (Fig. 8, not shown). In a modification, Fig. 9b, the commutator 91 is of planar type and is engaged by wheels 92 connected through mercury-cups 94.

Abstract: 1438453 Printing apparatus FRITZ BUSER AG MASCHINENFABRIK 28 Jan 1974 [29 Jan 1973] 03845/74 Heading B6C [Also in Division F2] Cylindrical printing screen 1 is supported on end ring 4, e.g. by adhesive, and connected to drive connection 11 with the intermediary of a universal joint formed by gimbal ring 12. The pivoting axes of the universal joint lie in a plane transverse to the axis of rotation of the end ring, this plane being coincident with, or closely adjacent to, a plane containing the end of the end ring nearer the drive connection. 0-rings 17 and 18 seal the gimbal from ink. End ring 4 may be connected to connecting ring 7 by a bayonet connection which leaves slots to allow escape of surplus ink. The drive connection may be driven by motor M through gear wheel 31 and gear ring 29. A pair of grooves on end ring 4 and connecting piece 7, together with an associated pin fix the screen in the required position.

Title: Improvements relating to centrifugal pumps
IPC: F04D9/02
Filed: 1951-02-16
Abstract: 679,246. Centrifugal pumps. VOLLAND, G. Feb. 16, 1951 [Oct. 30,1950], No. 3866/51. Class 110(i) In a self-priming centrifugal pump having an injector 7 arranged on the discharge side of the pump, the injector surrounds the impeller 1 over the whole or part of the periphery; the internal width of the injector at entry is about equal to the internal width of the impeller at outlet, and the crosssection increases towards the pressure chamber 5. When the pump is started, a circulation of water between the injector and the chamber 5 is established, as shown at 10. The air in the suction pipe of the pump is thereby entrained and expelled at 11 into the pump outlet 6. The injector is of rectangular cross-section. Its side walls 7<SP>1</SP> may be eliminated. If the pump has two stages, only one stage need have an injector. The internal width of the injector may be adjustable, so that the passage area can be reduced during priming.

[Class 80 (ii)] A piston d, which is adjustably secured to a rod c hinged to an arm b<2> rigid with the clutch pedal b of a motor vehicle and which is mounted within a cylinder e hinged to one arm f of the clutch actuating lever, functions as a control valve for an engine-suction servomotor which assists in disengaging the clutch, the piston f<4> of the servo being adjustably connected to the other arm f<2> of the clutch lever while the cylinder f<5> is connected by a link f<6> to a fixed eye f<7>. In the normal position of the pedal, the piston d is pressed against an end cap g of the cylinder e by a spring g<1>, in which position a port k in the cylinder e, communicating with the servo through a conduit k<2>, is open to the atmosphere through an annular groove j<3> and ports j<1>, j<2> in the piston and a port j in the cylinder.

Abstract: 1,083,319. Lubricating; dash-pots. SHIBAURA KYODO KOGYO KABUSHIKI KAISHA. Feb. 2, 1966 [Feb. 3, 1965; March 25, 1965; Oct. 14, 1965], No. 4664/66. Headings F2A and F2S. Apparatus lubricating bodies translationally moving along a path comprises a support movable generally parallel to the path and which carries a guide member and a lubricating mechanism and means advancing and retracting the member and mechanism to and from said path. In Fig. 1 a support 13 forms part of a parallelogram linkage and moves in an arc while remaining parallel to the path of conveyer rollers 10. The linkage is returned by spring 23 to a first position and operates switch 21 to introduce fluid into cylinder 20 to extend guide rod 18. When a roller 10 engages rod 18 the support 13 is moved and nozzle 31 (Fig. 2) on the end of hollow cylinder 28 engages nipple 12 on roller 10 and is then depressed and the quantity of lubricant in cylinder 26 is forced through valve 30, nozzle 31 and nipple 12. The linkage moves on so that nozzle 31 is disengaged and piston 28 is extended by spring 32 and cylinder 26 refills from tank 25. When the linkage reaches a second position it operates switch 22 and fluid is discharged from cylinder 20 and rod 18 retracts and allows return of the linkage to the first position. In Fig. 3 (not shown), the lubricating and guide rod mechanisms are combined in a unitary structure comprising a number of concentric pistons and cylinders. Shock absorber.-When the linkage returns to the restored position it strikes a shock absorber, Fig. 4, not shown. Link (44) deforms resilient seat (74) and closes vent (75) and then depresses piston (72), air leaving the cylinder via valve (77) when it has reached a certain pressure.

The upper end of the lamp is mounted in a bearing in a rotary table 7 provided with a handle 5 which is operated manually to rotate the table 7 about its axis to clamp the end of the lamp in the bearing, and the table is provided with wire-capturing members 18 formed with teeth 20 to co-operate with teeth 19 to grip the wires 22. At the other end of the lamp a spindle 8 mounted in a cylindrical socket 9 in an annular plate 1 supports a rotary table 6 provided with vertical members 12 which terminate in teeth 13 arranged to grip the lead-in wires 21 against teeth 14 on the fixed contacts 4. Rotary movement is imparted to the table 6 by providing its spindle 8 with a radial pin 11 which engages within a helical slot 10 in the wall of the socket 9, the slot being formed with an upper offset 10<SP>1</SP> which provides an upper detent for the pin, and a lower offset 24 which retains the pin in a position such that the co-operating teeth grip the wires 21 after the pin has been freed from detent 10<SP>1</SP> and has descended, under gravity, with the table 6.
