A rotary engine of the movable-abutment type comprises a cylindrical rotor g, Fig. 1, having one or more (two shown) arcuate recesses in the rotor circumference forming with the centre casing a and end flanges s thrust chambers r and a plurality of rotary (six shown) abutments v which through gearing (n), (o), (p), Figs. 2, 3 (not shown) rotate in timed sequence with the rotor in the same direction. Pressure fluid is admitted to each chamber through an axial-rotor passage h and radial rotor passages l to act on rotor faces b to drive an output shaft (3) and exhausts through rotor passages i, openings j  and apertures in end flanges (s) of the casing. During rotation the pressure fluid bears for part of the time on two abutments, the pressure automatically decreasing on the leading, i.e., downstream abutment in the rotational direction of the rotor and increasing on the upstream abutment. A fan (u) driven by the shaft (3) cools the casing and the cooling medium, e.g., air passes through passages (x) and t to cool the rotor. The rotor is shown in other embodiments having two recesses with eight engaging abutments, three equally spaced recesses with five abutments and one recess with three abutments. In another embodiment each abutment V is connected by a crank-arm to its gear O so that instead of rotating the abutment V oscillates. Several such engines may be coupled together.

Abstract: 918,764. Tyre bead breakers. DUNLOP RUBBER CO Ltd. June 5, 1959 [June 19, 1958], No 19587/58. Class 144 (1) A tool for breaking tyre beads away from their seatings on a wheel rim comprises a clamp 1 to grip the wheel rim flange 2 and a fluid-pressure operated jack 4 pivotally connected to the clamp so that in use its piston-rod 5 is directed towards the tyre bead, the piston-rod having a tapered end spigot 6 for loose detachable connection with a bead breaking wedge 8 whereby, on actuation of the jack the wedge is forced between the tyre bead and the rim flange seating surface 11, and on reverse actuation of the jack the wedge is left behind to hold the bead spaced from its rim seating. As shown, the clamp comprises a base-plate 12 having a lower jaw 15 attached to its front edge and an upstanding plate 13 at each side to journal a crosspin 17 on which are pivotally mounted a pair of upper jaw members 18. Each jaw member 18 carries a clamp bolt 19 at its rear end to bear on the base-plate 12 and provide for gripping adjustment of the jaw members relative to the jaw 15. A reaction bolt 24 is also pivotally supported between the plates 13 to bear against the wheel or wheel rim and prevent rotation of the clamp 4 during bead breaking oper tion of the jack. To avoid damage to the tyre engaging side of the rim flange 2, the clamp jaw members 18 have convex cylindrical gripping- surfaces 33 angularly disposed to conform with the contour of the flange circumference and to provide line contact therewith. The lower jaw 15, however, has a pair of circumferentially disposed inclined knife edges 31 and a pair of axially disposed knife edges 32 to bite into the underside of the rim flange. The side plates 13 carry mutually facing trunnion pins 20 at their upper ends for detachable pivotal engagement with recesses in a collar 29 carried by the front end of the cylinder of the jack 4, and the pistonrod 5 has a frusto-conical spigot 6 at its end for loose detachable engagement in a complementary bore in the wedge 8. The wedge 8 has a curved face to ride down over the bead and terminates in a tip 34 of soft metal, such as bronze, to avoid damage to the rim base. Reference has been directed by the Comptroller to Specification 791,572.

Title: New or improved process for the impregnation with rubber of textile yarns and fibres
Filed: 1932-07-13
Abstract: <PICT:0408931/IV/1> Textile materials such as yarns, threads, and cords are impregnated with a rubber-containing liquid such as latex or rubber solution by loosely winding on a foraminous holder, forcing the liquid between the windings, passing a compressed gas such as air between the windings and subsequently drying and vulcanizing the wound package.  Both the liquid and air may be passed through the material in opposite directions alternately.  The liquid is preferably diluted latex containing ammonia, ammonium polysulphide, an accelerator, an activator and an anti-oxidant. To remove materials such as oil prior to impregnation, the package may be boiled in soft water containing a wetting-out agent such as a sulphonated fatty alcohol and dried.  Wound packages 20, 21, 22 clamped at 23, 24 are contained in a fluid-tight vessel 11 which is supplied with liquid from a storage tank 13 by a circulating tank 12 in conjunction with pipe lines 26, 27, 28, 29, 30 (shown as continuous single lines), a centrifugal pump 14 and two-way cocks 15, 16.  Pipe lines 31, 32, 33, 34, 35 (shown as dot and dash lines) convey the liquid through the material in the opposite direction.  Air is supplied from a compressor 17 through a receiver 18, a two-way cock 19 allowing the compressed air either to be supplied to the vessel 11 by a pipe 40 or to force liquid from the tank 13 to the tank 12.  If desired, the material may be impregnated first with a dilute and then with a more concentrated latex.
