Abstract: Polymers of butadiene in which at least 80% of the units are in a cis-1,4 configuration are made by polymerizing butadiene in the presence of a catalyst system formed by mixing (1) TiCl3I, (2) an organo-aluminium compound of the formula AlR3 or AlR2X, in which each R is a hydrocarbon radical and X is a halogen atom, and (3) an organic ether.  Specified aluminium compounds are aluminium trimethyl, triethyl, triisobutyl, trihexadecyl, triphenyl, monomethyldiethyl, monoethyldimethyl, diethylmonochloride, and diisobutyl monobromide.  The organic ether may be methyl, diethyl, din-propyl, diisopropyl, di-n-butyl, methyl ethyl, isopropyl ethyl, or isopropyl methyl ether, or ethylene oxide, furan, furfural, tetrahydrofuran, dioxane, or morpholine.  The catalyst system may be preformed or formed in situ.  The polymerization is generally effected in a hydrocarbon diluent, which may be dried by distillation over aluminium triisobutyl.

[Class 85.] In an oil or gas well with free flow or gas-lift, a flow-restricting device is arranged in the well, the opening in the device being controlled by moving tubing in a rectilinear path from the top of the well, the upper end of the tubing telescoping in the inlet end of a flow line. In Fig. 1 a valve head 10, with a cone tip 12 and flow apertures 11, is fixed at a desired point in the well and is secured to a tube 17 ; a sleeve 13 moves within the tube 17 and has an annular shoulder 14 co-operating with the head 10 to cut off or vary the flow, a skirt 16 depending from the sleeve 13. This sleeve is secured to tubing 20 held against rotation by a spline 23a and provided with a fixed flange 26 engaged by a divided, threaded member 28 which is raised or lowered by a right and left-hand threaded nut 31 to adjust the sleeve 13. Above the well is a further flow restricting means 34 as described in Specification 378,282. In Fig. 8 the flow adjustment is effected by a piston 26a secured to the tubing 18a, the adjustment being effected by pumping fluid from a container through pipe 36a to below the piston or by allowing the fluid to return to the container through pipe 40a. A gauge on the container, or indicating means 45a, 47a shows the position of the piston. The tubing 18a is held after adjustment by wedge slips 16a controlled by a handle 12a.

Title: Apparatus for the removal of projecting excess weld material
IPC: B23K37/08
Filed: 1977-09-23
Abstract: In the device, two cross members (15, 16) and two guide tubes (13, 14) for guiding two hydraulic cylinders (18) form a frame for the acceptance of the reaction forces which occur during the shearing-off process. The hydraulic cylinders are connected to one another by a further cross member (20), on which one (21) of the shearing cutters is arranged, the said cutter being moved towards the other shearing cutter (19), arranged on the cross member (16) of the frame, when the hydraulic cylinders (18) are pressurised. The piston rods of the hydraulic cylinders (18), which cylinders can be moved in the guide tubes (13, 14), are firmly connected to the cross member (15) of the frame. Due to the fact that the reaction forces can be taken up by the frame, the hydraulic cylinders and hence the entire device can be kept small. <IMAGE>

Abstract: 917,728. Television. TOKYO SHIBAURA ELECTRIC CO. Ltd. Nov. 22, 1960 [Nov. 30, 1959], No. 40165/60. Class 40 (3). Television signals derived from a magnetic tape 1 (Fig. 1), on which complete fields are recorded on each track, such as 2 1 , 2 2  by means of a single rotating transducer head with field synchronizing signals recorded on marginal portions 3, 4 have some of the latter signal periods blanked and during such periods regenerated synchronizing signals are inserted to replace such signals inevitably lost during the period in which the head transfers from the end of one track to the beginning of the next track. As shown in Fig. 2, the signals derived, by known means, from the tape are supplied via terminal 5 to one input of a switch 6, which, during field picture signal portions, supplies such input signals to an output terminal 7 and a synchronizing signal separator 8. The output from the latter is supplied to a pulse generator 9, and to a field pulse separator 10, the output from which controls generator 9 to produce pulses of line period and of half-line period. These pulses are then supplied to a second input of switch 6 which is operated by a gating pulse from a generator 11 controlled by field synchronizing signals from separator 10 to interrupt the signal input from terminal 5 and to supply instead the input signals from generator 9 to output terminal 7. The generator 9 includes an A.F.C. circuit of large time constant so that output signals continue to be supplied in the event that the tape signals are intermittently omitted. The length of the gating signals from generator 11 may be adjusted. U.S.A. Specifications 2,773,120, 2,866,012 and 2,919,314 are referred to.

A rotary fluid-actuated motor comprises a pair of abutment rings or stators 1, Fig. 1, which are separated from each other by a spacing piece 3 and are clamped between a pair of manifolds for inlet and outlet of working fluid, respectively, a rotor 5 being lodged within each stator and having a plurality of lobes 6, Fig. 2, which engage with radial vanes 12 in the associated stator. An outer stationary ring 2 coaxial with each stator is spaced apart therefrom so as to define an annular space 24 that is filled with fluid whose pressure balances the pressure of working fluid between the stator and the rotor. Each of the vanes 12 is situated in a groove providing a space 10 into which fluid enters from the high-pressure side of the vane through clearance spaces between the vane and the sides of the groove so that the vane is pressed against the periphery of the corresponding rotor. The radially outermost edge of each vane engages with a rocker arm 14 that is mounted on a pivot 13, which is pressed towards the rotor by spring-loaded plungers 15 lodged in a pair of slots 17 defined by a plugunit mounted in a cylindrical aperture or cut-out (9), Fig.4 (not shown), within the spacing piece 3, whereby initial loading of the vane is effected. Ports 19, 20 located on either side of each vane are connected to the manifolds by passages 20, 21, respectively. The space 24 is charged with fluid through passages 16, 18 connected to each of the spaces 10, said passages being in the plugunits and the lateral faces of the spacing piece 3, respectively. The rotors are arranged to operate in anti-phase relationship relative to each other so as to effect a smooth torque output, the vanes and the ports in the stators being situated accordingly as indicated by phantom lines in Fig.2. The stators may be made of a wear-resistant material e.g. spheroidal graphitic iron whereas the rings 2 may be made of high-tensile steel. Alternatively, the space 24 is charged with pressurized fluid supplied by an external source. The motor is capable of operating as a pump.
