Title: Actuator-overcap for a pressurised aerosol dispensing container
IPC: B65D83/14
Filed: 1972-04-28
Abstract: 1340320 Pressurized dispensing containers RISDON MFG CO 28 April 1972 [15 Feb 1972] 19873/72 Heading F1R A valve actuator button cap assembly for a dispensing container includes complementary keying elements formed on the button and a collar adapted to be mounted on the valved end of a container, which elements when aligned by relative rotation of the button and collar permit actuation of the valve, otherwise the elements prevent valve actuation, means being provided to indicate visually when the elements are in alignment. As shown in Fig. 2 button 32 is rotatable with overcap 30 to bring axial element 68 into alignment with notch element 66 in a collar 60 secured to the container; mark 70 may be viewed through window 72 when the elements are aligned. In the embodiment of Fig. 6 the collar 160 is rotatably mounted on the pedestal 162 and has an arm 163 having a mark 170 viewable through window 172 when a plug 173 is removed and the cap 130 is rotated to align the elements. With the plug in position it engages the arm 163 whereby the cap rotates the collar with the elements out of alignment. In a third embodiment Fig.10 (not shown) the collar has a lever which projects through a stepped aperture in the overcap, alignment being effected by lifting the lever from one step to the other.

Title: Improvements in or relating to hydraulic power transmission apparatus
IPC: F16H39/02
Filed: 1924-08-23
Abstract: 237,116. Rushen, P. C., (Winship, E.). Aug. 23, 1924. Revolving-cylinder pumps. - A hydraulic variable-speed gear comprises a pump body on the driving shaft 24, Fig. 1, a motor body on the driven shaft 157, Fig. 3, the pump swash-plate 44 bearing against an inclined disc 54 connected to the driven shaft, and the motor swash-plate against a disc 149 of variable inclination, the degree of inclination being variable in accordance with variations in the liquid pressure. A rotary distributing valve 71 on the driven shaft co-operates with a fixed plate 63 to govern the connection of the pump cylinders with high and low pressure chambers, which are connected with the motor by conduits 86, 87, valves 96, 97 being provided so that the direction of flow through the motor may be reversed. A short-circuiting valve is also provided. The pump and motor cylinders are so mounted that they may rock slightly on their shafts, the mounting comprising a collar 34 with radial pins 35, and blocks 36 on the pins with curved heads 38 and parallel sides received in longitudinal slots, and are spring-pressed against their valve or face-plates. The disc 149 is connected to pistons 165, 166, the piston of smaller area being permanently acted on by the high-pressure liquid through a port 167, while the piston 166 is only acted on by the high-pressure liquid through a port 176, Fig. 9, when the pressure increases sufficiently to overcome a spring 172 and move a valve 171 to uncover the port, the inclination of the disc 149 being then increased. When the pressure diminishes, the spring moves the valve so that the piston 166 is acted on by low-pressure liquid through ports 175, 178, and the inclination of the disc 149 is diminished. The pump and motor casings are connected to a vacuum tank for maintaining sub-atmospheric pressure in the casings and collecting leakage liquid, which is returned to the low-pressure chamber.

Title: Apparatus for cutting rubberized fabric
IPC: B26D1/20
Filed: 1973-04-27
Abstract: 1433211 Shearing B F GOODRICH CO 27 April 1973 20038/73 Heading B3W Cutting apparatus for cutting rubberised fabric, particularly bias cutting such fabric having longitudinally extending wires embedded in it, comprises a power driven carriage reciprocable on a support frame, a pair of driven cutters, rotatably mounted on the carriage and spaced in the direction of its reciprocation, a guide bar, secured to the frame, over which fab - ric is moved and under which a conveyor belt travels, anvil means, having a linear cutting edge, and biasing means connected to each cutter to bias it into shearing contact with the cutting edge of the anvil means. The support frame 15 is mounted on wheels 23 for movement about a pivot 22 to vary the bias angle. The carriage 32 is reciprocable between limit switches on a rail 31 secured to the upper frame member 18 by a chain and sprocket drive 77-80 from a motor 76. Cutter units 24, 25 are suspended from the carriage 32, a spring 52 biasing each cutter shaft 45, extending through a respective housing 44, to the right, Fig. 5, to bring a cutter disc 47 into shearing engagement with a straight cutter 71. Each cutter 47 is disposed at an acute angle to its cutter 71 and comprises a plurality of cutter inserts (48),Fig. 3 (not shown), each having converging cutting edges (49), (50). A mounting block 72 of each cutter 71 is mounted on a respective housing 44 or integral cutters may have a single mounting block mounted on the housing of a motor 37 which, through a belt drive, rotates both cutter discs in the same direction. A flange 73 on each cutter 71 is guided in a recess in a guide bar 68 which extends across the frame. The upper run 11 of the conveyor, carrying fabric 85, is lifted over the tapered leading edge 69 of the bar 68 by a rod 20, on a plate 13 supporting the conveyor run 11. In operation, the frame 15 having been immobilized at the desired bias angle, the conveyor is actuated to feed a predetermined length of fabric over the bar 68. Clamps 64 are actuated by pneumatic cylinders 62 and motors 76 and 37 are energized. Whichever is the leading cutting unit shears the fabric against its cutter 71. Limit switches (LS-1) (LS-2), Fig. 2, (not shown) control rotation of the cutters and reciprocation of the carriage. Further feed takes place and the carriage is moved in the opposite direction, the other cutter unit now leading and therefore shearing the fabric. The housings 44 may each comprise the cylinder of a pneumatic device which is pressurized to move the inoperative rotary cutter away from its cutter 71 to avoid interference with the action of the cutter. Means may be provided, Fig. 7 (not shown), for varying the cutting angle B, C between the cutter discs and their cutters 71.

IPC: H01B7/08
Filed: 1955-07-12
Abstract: 796,419. Slot winding insulation for dynamoelectric machines. ENGLISH ELECTRIC CO., Ltd. Oct. 12, 1956 [July 12, 1955], No. 20137/55. Class 35. Slot conductors are secured and insulated by obliquely winding tape alternately around and between the conductors, the edges of the tape abutting but not overlapping. As shown for an even number of conductors 10-15, a single tape 16 is wound from B across the front of the stack, over the top at C, and then interlacing the conductors down to D, and thence across the back in the reverse direction from D to E and so on. Conventional insulation is then wound on. Uneven numbers of conductors are secured by a pair of half-width tapes wound in opposite directions without overlap. Where a conductor leaves a group to make a connection, the conversion from odd to even method of binding is achieved by tapering the tape from the even section to half-width and winding the additional half-width tape down the conductor which leaves the group, and thence in conjunction with the reduced existing tape on the odd part. Instead of reducing the width by tapering, it may be done by doubling along its length. The overhangs may be secured in the same manner. The tape may be thick fabric of glass, asbestos, quartz or alumina fibres.
