Title: Tyre building stitcher assembly
IPC: B29D30/00
Filed: 1975-05-20
Abstract: 1506774 Stitching tyres NATIONAL STANDARD CO 20 May 1975 [12 July 1974] 21444/75 Heading B7C A stitcher assembly in a tyre building machine comprises a pair of carriers 228 each pivotally carrying an arm 242 at the free end of which is a stitching means, e.g. a pair of stitching rollers 260. Each carrier 228 is slidable axially of a building drum along rod 218 of a respective unit 212 when lead screw 220 is rotated by an electric motor via a shaft 204, a pinion 196, shaft 194 and a worm 198. The units 212 are themselves rotatable about axes of shafts 194 by an electric motor via shaft 206, gears 190 and sleeves 188 to which the units 212 are secured. The axes of shafts 194 are normal to the drum axis. Supports 172 in which shafts 194 and sleeves 188 are journalled are indexable axially of the drum towards and away from each other upon manual rotation of shaft 154 due to interacting screw threads (138, 176 and 156, 176) (Fig. 12, not shown). The shaft 154 is journalled in a unit 138 and the latter is movable in a frame 108 upon manual rotation of shaft 120. The frame 108 is pivotally mounted on the machine frame about an axis parallel to the drum axis for movement upon inflation of air bags 118 between stops 113 and 117. Air bags 256 when inflated move the stitching rollers into engagement with tyre components on the building drum 58. Shafts 250 pivotally mounting the arms 242 on the carriers 228 are axially movable relative thereto against bias of springs (254) (Fig. 7, not shown), if the supports 172 are moved too close together upon rotation of shaft 154. For stitching the cylindrical carcass plies, air bags 118, 256 are inflated and the rollers 260 assume the radially innermost position of Fig. 3. Deflation of the bags, expansion of the central portion of the drum application of a tread, and sidewalls and subsequent inflation of bags 256 brings the rollers into stitching engagement with the tread. Stitching of the tread is accomplished by indexing the carriers 228 along the units 212 when the latter are parallel to the drum axis. The sidewalls are stitched by indexing the carriers 228 along the units 212 when the latter are positioned with their shafts 194 in the shoulder regions of the tyre and are rotated about the axes of those shafts (see Fig. 13). If the tread overlies the sidewalls or vice versa the rollers are indexed along the units 212 with rotation of the latter over the shoulders from the tread to the sidewalls or from the sidewalls to the tread, respectively.

Filed: 1943-12-22
Abstract: A filler, e.g. kieselguhr or kaolin, is incorporated in a thin film or sheet of plasticised ethyl cellulose, to impart a roughened surface and thus improve the bonding with an adhesive with which one face is coated.  Vegetable oils or derived fatty acids may be used as plasticisers and any suitable adhesive may be used.  In an example a film formed of four parts ethyl cellulose, four parts castor oil, and one part kaolin is described.  The Provisional Specification describes the use both of unroughened films and of films roughened by casting on to roughened glass.ALSO:A filler, e.g., kieselguhr or kaolin, is incorporated in a thin film or sheet of plasticized ethyl cellulose, for use as an adhesive surgical dressing or plaster, to impart a roughened surface and thus improve the bonding with an adhesive with which one face is coated.

In a clip, e.g. for braces, of the type comprising a base plate 3, a spring plate 8 movable about one of its ends relative to the base plate, said one end engaging against a portion 5 of the base plate bent upward from one end thereof substantially at right angles to the general plane of the base plate, and a ibiassing lever 14 pivotally mounted on the base plate and operable to bias the spring plate 8 into clamping engagement with the base plate 3, the end portion of the spring plate 8 is supported against an abutment surface 6 provided on the inner face of the portion 5. As described the abutment surface 6 is formed by bending up a flap having an aperture 25 from the base plate 3, and is engaged by inclined tongues 7 at the end of the base plate 8 which is stepped centrally. The lever 14 is pivoted by means of journals 13 in bearing posts 11 bent up from the base plate and having bent over end flanges 24. The journals 13 are displaced from the junction between the two arms of the lever 14 along the longer arm thereof to reduce the distance between the lever and the portion 5. The base plate 3 has strengthening ribs 4 and the plates 3, and 8 have jaw pieces 23, and 16 respectively rivetted thereto. In a second embodiment no flap is bent out of the base plate 3 and the tongues 7 are inserted into blind recess impressed in the inside face of the portion 5.

Title: A new or improved valve system for controlling intermittent movement of a piston in a cylinder under fluid pressure
IPC: F15B11/12
Filed: 1935-08-06
Abstract: 455,813. Fluid-pressure servomotors. BENDIX, Ltd., and WYNNE, C. H. L., King's Road, Tyseley, Birmingham. Aug. 6, 1935, No. 22094. [Class 135] A valve device for controlling the intermittent movement of a piston 2 in a cylinder 1, for instance in the gear-shifting mechanism of change-speed gears or of reversing gear for marine power units, comprises a main ported control piston 12 which can be moved a certain distance before entraining two auxiliary ported control-pistons 20, 24, the three pistons being slidable in a bore 4 having ports 5, 7, 8 leading to the cylinder 1 and a port 11 connected to a source of vacuum or fluid-pressure. The piston 2 may occupy either end position or the central position in the cylinder 1 according to the position of the piston 12. The latter has a groove 14 continuously in communication with the port 11, which groove communicates through passages 15, 16 with three ports 17, 18, 19 so spaced with respect to the ports 5, 7, 8 that only one of them communicates with the cylinder at once. The piston 20 is loose on a reduced part of the operating spindle 13 which is terminated by a collar 23 whilst the piston 24 is similarly loose on a headed rod 25 screwed into the piston 12. The ends of the cylinder 1 are connected to the ports 7, 8 by passages 9, 10 respectively and are vented through the open ends of the bore 4 by longitudinal passages 21, 26 in the respective auxiliary pistons when the piston 12 has moved out of contact therewith and clear of the respective port 7 or 8. Further ports 22, 27 lead into the passages 21, 26 respectively and vent the ends of the cylinder in the respective end positions of the valve device. Unlike the piston 12, the pistons 20, 24 need only be a loose fit in the bore 4 and their movement therein due to vibration may be prevented by spring-pressed balls 28. When the piston 12 is moved from the position shown back to the central position in which the ports 5, 17 register, the port 8 is first cut off from the atmosphere. The vacuum in the left hand end of the cylinder 1 then draws the piston 2 back to the central position where it cuts off the port 5. To prevent the piston 2 overshooting the central position due to a sudden cessation of the resistance to its movement, a passage 31 thersthrough is opened by a plunger valve 32 opened by the vacuum through ports 5, 33 against the action of a spring in the centre position. Alternatively the two sides of the piston may communicate through a small permanently-open passage in the piston rod 3. The ports 17, 18, 19 may communicate directly with a segmental groove which dispenses with passages 15, 16.

Preferably, the damping of the circuit is adjusted to make the degree of amplification the same for all frequencies. Similar correcting circuits tuned to lower frequencies may be added. The amplifier may be used at the receiver or transmitter.
