Abstract: 1,207,072. Centrifugal pumps. R. M. FAYS, R.J. FAYS and R.H. FAYS. March 4, 1969 [March 5, 1968], No.11483/69. Heading F1C. [Also in Division H2] A centrifugal pump comprising a casing 1, Fig. 1, having an inlet 2 and an outlet 3, has one or more magnetizable rolling pumping elements 6, 7 rotated around an annular race 4, 5 by a rotating magnetic field. The elements also rotate about their own axes and thereby produce the centrifugal pumping effect. The elements may be spherical as shown, or ellipsoidal or cylindrical. The rotating magnetic field is created by a rotating U-shaped permanent magnet 9 or a rotating electromagnet, or by a circular group of stationary electromagnets energized by an A. C. current through a rotary contact. The inlet 2 need not be central as shown, and may be inclined to the casing to introduce fluid into the casing with a swirling motion. The outlet 3 may be radial or tangential. The elements may be coated with corrosion resistant p. t. f.e. or polyacrylic resin. The race may be coated with polyacrylic resin, and the casing may be of p. t. f. e. or of reinforced transparent material.

Title: Improvements in or relating to doors for motor-cars or like vehicles
IPC: B60J5/04
Filed: 1930-04-11
Abstract: 352,536. Vehicle doors ; fastenings. MACKENZIE, D. G., 388, Olivier Avenue, Montreal, Canada. April 11, 1930, No. 11506. [Class 103 (ii).] In order to increase the available height of the door space for passengers entering a motor-car or like vehicle and to lessen the projection of the doors when .open, the doors 12 are supported and adapted to turn about horizontal pivots 13 arranged upon a central longitudinal roof beam 10, and open in an upward direction. Preferably the doors, as shown, are of L-shape and control members comprising springs 14, cords or cables 16, and hinged straps 18 are connected between the angle of the L and the remote side of hinge plates 11, so that, after an initial lifting of the door by the passenger, the springs 14 exert a continuously increasing effort on the door and ultimately complete the opening movement. During the closing movement the pull of the springs gradually decreases, thus allowing the door finally to slam to under its own weight or with little effort on the part of the passenger. Locking-bolts 23 and operating-rods 22, Fig. 4, are arranged at the lower end of each door and are connected to opposite sides of the pivot of a lever 21 actuated from the inside of the vehicle by a handle 20 and from the outside by a handle and cam 24. A weathertight joint between the door and vehicle body is obtained by fitting on the door a U-shaped channel 12a, Fig. 5, having a base strip of fabric 25, and by forming the door frame with a complementary channel 26, a fabric overlap 27 on the door completing the joint. The portion of each door extending across the roof may have an opening therein closable when desired by a strip of fabric or by other means.

Title: Ac power transmission
IPC: H02J3/00
Filed: 1975-03-20
Abstract: 1488442 Interconnected three phase systems OTDEL ENERGETICH KIBERNETI AKAD NAUK MOLDAVSK SSR 20 March 1975 [21 March 1974] 11562/75 Heading H2H A power transmission system comprises a link which interconnects two three phase systems, the conductors of the link being arranged in three pairs, means being provided whereby the voltages applied to the conductors of each pair of lines may be shifted in phase relative to one another. Two three phase systems 1 are interconnected by a link which includes conductors 2, 3, the conductors of the link being arranged in three pairs, each pair having a conductor 2 and a conductor 3. The conductors 2 are connected to the systems 1 by voltage phase shifting devices 4 and switches 7 whilst the conductors 3 are connected by similar devices 4 and switches 8. Furthermore the conductors 2, 3 of each pair have capacitors 5 connected thereacross whilst inductors 6 are connected to conductors 2, 3 of different pairs. The voltage phase shifting devices 4-which may be a type of transformer-allow adjustment to be made of the angles # between the voltages applied to the conductors 2, 3 of each pair in the interconnecting link whereby the power transmitted along the link may be controlled, the adjustment of the angles # between the conductors 2, 3 of each of the pairs being equal. The provision of the capacitors 5 serves to increase the power transmitted whilst the provision of the inductors 6 serves to decrease the power transmitted, both as a function of the angle #. The variation of the angle # may be made in one discrete step by an extra set of switches where the conductors 3 may be connected in phase or anti-phase to the conductors 2. The system may also function as a fault protection system by opening the relevant set of switches 7 or 8 so that one set of conductors 2 or 3 is open-ended to serve as a balancing resistor. Alternatively systems of spark-gaps, switches and variable resistors may be connected to the conductors 2, 3 between the switches 7, 8 and the devices 4 so that the variable resistors are connected to the conductors when these conductors become disconnected, the resistors being adjustable according to the loading on the transmission link.

Abstract: 967,384. Milling. KEARNEY & TRECKER CORPORATION. March 30, 1961 [May 27, 1960], No. 11693/61. Heading B3K. [Also in Division F2] A manually operated valve 981 of a horizontal or vertical milling machine controls feed and rapid traverse clutches 992, 993 of the worktable drive and an interlock servo 988 normally moves the valve spool 981 to a neutral position, in which both clutches are connected to drain 996 when a spindle brake 181 is energized. The manual control 986 may override the servo action to selectively engage either clutch 992, 993 when the brake is engaged. Selective engagement of the clutches 992, 993 drives a shaft 1042 at rapid traverse or feed speed respectively for each ratio of a worktable gear, and the shaft 1042 drives the worktable 41, saddle spindle 51 and knee spindle 55 selectively in either forward or reverse direction upon selective engagement of reversing clutches 1072, 1051, 1061. The work spindle 57 or 761 is driven from an electric motor 58 through a change-speed gear providing twenty-four forward ratios and in which gear sliding gear pairs 101, 121, 126, 146 and 166 are operated by two position differential pistons and cylinders 300 ... 304 under the control of a manually operable rotary distributer valve 275. During ratio shift an hydraulically operable main friction clutch 77 is disengaged and a liquid pressure actuated brake 181 applied to the work spindle 57. Gradual clutch engagement is ensured by a timer valve 576 and an interlock prevents ratio shift whilst the clutch is engaged. A similar gear (Fig. 17, not shown) and control 979 is provided for the worktable drive.

[Class 74 (ii).] In a knitting-machine having means to supply ground and warp threads to the needles the warp thread draw-off device is formed or fitted, with means to impart tension to each warp thread substantially at the moment of completion of the loop-drawing movement of the needle. After each needle has been raised, its associated thread feeder is moved outwardly by cam 17, and simultaneously a cam 21 draws off sufficient warp thread to wrap round the needle. The feeder is then deflected by a cam 19, and retracted by a return cam not shown, the yarn being yielded to the needle down the rear slope of the cam 21. A cam 22 now draws off sufficient warp thread for loop formation, and finally, as the needle nears the lowest point of the stitch-cam 26 a cam 18 re-projects the feeder, so as to hold the thread forwardly into the hook of the needle. As the needle reaches its lowest point, a cam 23 applies tension to the warp thread.
