IPC: B29C48/90
Filed: 1968-06-17
Abstract: 1,202,961. Making tubular film; sizing dies. IMPERIAL CHEMICAL INDUSTRIES Ltd. 19 May, 1969 [17 June, 1968], No. 28681/68. Headings B5A and B5B. Apparatus for producing tubular film comprises a vacuum sizing die and a " contraction die " connected together to form a continuous passage therethrough. The vacuum die disclosed has a highly polished central passage 1 at each end of which is a ring of holes 16, 17 connected to a source of vacuum via chambers 7, 8, pipes 10, 11 and outlet 13. The centre of the passage is cooled, e.g. by water, circulated through zone 9 via pipes 14, 15. The " contraction die " has a central passage 23 accurately aligned with that of the vacuum die and which decreases in diameter towards the outlet, but which may have the walls of its final portion parallel. This die allows the tube to contract while preventing water entering the vacuum die from a cooling bath in which the whole may be submerged. The manufacture of tubes of poly- (4-methylpentene-1) is exemplified, and the taper on the contraction die for a 1 inch dia. tube of this polymer is about 0À01 inch.

Title: Improvements in engine starter drives
IPC: F02N15/06
Filed: 1932-10-15
Abstract: 410,465. Turning-gear. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. Oct. 15, 1932, No. 28866. Convention date, Oct. 17, 1931. [Class 7 (v).] In an engine starter, a pinion or other engaging member is moved axially into and out of engagement with an engine member by a pin-and-slot connection with a driving member, and in the engaging position is driven through a resilient connection. As shown, the pinion 21 is connected through a drive spring 22 to a collar 18 slidable on a sleeve 12 mounted between seat portions 5, 6 on a driving member 2 secured by a set screw 4 to the starter shaft 1. The sleeve 12 is formed from a blank shown in Fig. 6, having edges 16, 17 which, when the blank is rolled into a sleeve, form an inclined slot for engagement by a pin 19 on the collar 18. The member 2 is formed adjacent to the seat portion 5 with an arcuate flange 7 terminating in abutment faces 9, 11 and undercut at 8, Fig. 5. A lug 13 on the end of the sleeve 12 engages between the abutment faces 9, 11. On rotation of the shaft 1, axial movement of the collar 18 and the pinion 21 is effected by the pin-and-slot connection between the collar 18 and the sleeve 12, and the abutment face 11 comes into driving engagement with a projection 28 on the collar 18, through which and the spring 22 the pinion is then driven. If the teeth of the pinion clash with those of the engine gear 27, the spring 22 will be compressed sufficiently to allow the pin 19 to move from the part 16<a> of the edge of the slot to a part 16c of higher pitch ; a force having a high rotary component is thus applied to the pinion, which is turned into meshing position. The pin 19 co-operates with one edge of the slot during the engaging movement of the pinion and with the other edge during the disengaging movement. The pinion is yielding- ly held, in either its retracted or its driving position, by the engagement of a spring detent 29 with one of the grooves 31, 32 in the shaft 1.

Abstract: 1,240,940. Ground anchors. H. WATANABE and S. GENMA. 11 June, 1969 [29 Nov., 1968; 14 Feb., 1969], No. 29509/69. Heading E1B. A ground anchor comprises first and second resistance plates 22, 23 pivotally interconnected by a rod 31 welded to plate 22 passing through connecting plates 31 which are welded to plate 23, a rotary plate 38 pivoted to the plate 23 by a similar rod 39, and a regulating plate 24 pivoted at one end at 48 to a bracket 47 mounted on the plate 22, and pivoted intermediate its ends at 51 to a guy plate 25 and a slotted connecting rod 26 which is also pivoted to the rod 39 of the rotary plate. The opposite end of the regulating plate has catch pawls 49 which engage the edge of the rotary plate when the anchor is in position to be driven into the ground by driving rod 50 which engages a screw threaded rod welded in a notch on the rotary plate 46 and the end of the regulating plate. Relative pivotal movement in clockwise direction of the plates 22, 23 and 38 is limited by stop plates 32 and 41 having extended arms 35 and 43 respectively, and the limited pivotal movement in the clockwise direction allowed by the shorter arms 36 is prevented by the rod 50 preventing movement of the regulating plate. When the anchor has been driven to almost its final position the driving rod is partially unscrewed and on further driving in the regulating plate can pivot and therefore the first and second resistance plates can pivot relative to one another and the rotary plate and they now follow an arcuate path until they are both substantially at right angles to the direction of the guy plate. In modifications additional resistance plates are included between the first and second plates. In a second embodiment the guy rod passes through a sleeve on the guy plate and has limited sliding movement therein, and the end thereof is screw threaded to engage a screw threaded recess on the rotary plate to prevent pivotal movement in the early stages of driving.
