Title: Improvements in or relating to moulds for thermoplastic pipe ends
Inventor: KILBURN ROBERT MARSHALL
IPC: B21J9/06
Filed: 1956-06-05
Abstract: A method of using the portable flange-forming tool of the parent Specification comprises placing an unflanged thermoplastic pipe in the tool with a length of pipe protruding, applying a setting device to the protruding pipe end to force it into the segmented collar of the tool until the portion of the pipe left protruding is of a length determined by the setting device, removing the setting device and operating the tool.  A washer with inwardly protruding prongs may be placed on the pipe before the setting device so that, on moulding the washer forms the back face of the flange formed on the pipe.  The setting device may be a metal sleeve with a bore for the mandrel of the tool and a bore for the thermoplastic pipe, the two bores at their junction forming an internal shoulder which contacts the end of the pipe and pushes it into the segmented collar until the end of the device contacts the collar.  This end of the device may have a recess for the washer.

Title: Apparatus for tensioning strip material for binding boxes, bales, crates and other bodies
IPC: B65B13/02
Filed: 1943-10-21
Abstract: 573,064. Strip-tensioning machines. PACKERS SUPPLY CO., Ltd., and ABBOTT, G. J. Oct. 21. 1943, No. 17372. Addition to 514,625. [Class 45] The apparatus of the parent Specification for tensioning strip material round boxes, bales, &c., is modified by providing a movable guard for the strip. It comprises a base 11 on which are mounted two cams 16, 17 carried by spindles 14, 15 and operated by handles 18, 19 respectively. The cam 16 holds the inner end 29A of the strip and the cam 17 holds the tensioned end 29B, springs 21 effecting the gripping and manual operation of the handles producing release. The gripping jaws for engaging and pulling the end 29B consist of a yoke 32 pivoted at 31 to the base 11 and formed with a curved foot 34A furnished with a central serrated plug. Pivoted at 37 to the yoke 32 is a mating shoe 39, the operating handle 38 being fixed on the shaft 37. The handle 38 in its final forward movement strikes a stop 45 about which it pivots and opens the gripping surfaces 34A, 39B, thus releasing the strip. On moving the handle 38 back, the gripping surfaces lightly slide over the strip, but when the handle is moved forward the strip is gripped and pulled through the clasp of the cam 17. Repeated to-and-fro action of the handle thus gradually tightens the strip, and the ends 29A, 29B are finally clamped together in any suitable manner. A side shield 41 tiltable about a pivot 42 may be moved aside to admit the strip 29B between the grip faces 34A, 39B and then turned down to retain the strip laterally. The cam 16 is stepped to allow the strip to pass it, and the end of the curve 39B is made tangential to the oncoming strip.

Filed: 1967-04-19
Abstract: 1,182,153. Sutures. ETHICON Inc. 19 April, 1967 [20 May, 1966], No. 17975/67. Heading. A5R. [Also in Division D1] A silk suture strand comprises a plurality of silk filaments coated with a silk substance comprising fibroin. The silk suture may comprise a plurality of silk fibres twisted together or a plurality of fibres braided together about a central core strand. The suture is coated with the fibroin such that it is non- capillary and so that the silk filaments become bonded together. The fibroin is extracted from natural silk in a solvent of aqueous lithium thiocyanate or lithium bromide which is then, after further treatment, used to coat the silk suture. After being used for dissolving the fibroin the thiocyanate or bromide and fibroin solution is either diluted using acetamide or diethylene dioxide or the thiocyanate or bromide is removed from the solution by dialysis against, e.g. urea. The suture is coated in the fibroin by immersion in the solution under a vacuum and then it is removed from the solution and drained and dried optionally while under tension. The fibroin coating may be fixed by salt solutions. The suture may be coated twice or three times and the thickness of the coating may be limited by passing the wet suture through an orifice.

Title: Improvements in and relating to boring or reaming apparatus for use on internal combustion engine cylinders
IPC: B23Q9/00
Filed: 1933-06-23
Abstract: 414,502. Drilling-machines. AUTOMOTIVE MAINTENANCE MACHINERY CO., 816, West Washington Boulevard, Chicago, U.S.A. June 23, 1933, No. 17979. Convention date, July 16, 1932. [Class 83 (iii).] In a portable machine for removing the ridge left at the top of the cylinder of an internal-combustion engine by the wear of the piston rings on the cylinder walls, a member X, Fig. 4, is adapted to be secured to the worn part 11 of a cylinder and to rotatably support a boring-head 22 for acting on the unworn ridge 12. The member X comprises a sleeve 21 attached to a disc 13 which carries three pins 14 on which a disc 15 is slidable. Radial slots 17, 18 in the adjacent faces of the discs receive and guide three gripping pieces 16, whose lower faces are bevelled at 16b to coact with similar surfaces 18a in the slots 18 so that movement of the disc 15 towards the disc 13 will expand the gripping pieces against the cylinder walls 11. A spring band 19 passes round recesses in the gripping pieces 16 to contract them. Axial movement of the disc 15 is caused by a central spindle 20 screwing in the disc and rotated by a knurled wheel 29. The spindle 20 is prevented from moving axially by a collar 31 thereon engaging the end of the sleeve 21 and by the wheel 29 engaging between upper and lower surfaces on a head 28 attached to the boring-head 22. Axial movement of the boring-head on the sleeve 21 is prevented by a spring-pressed ball 25 on the head engaging an annular recess 24 on the sleeve, this ball also serving to give a restraint to the free rotation of the head on the sleeve. The cutter 33, Figs. 3 and 5, is slidably mounted in a transverse recess 35 in an offset portion 34 of the head 22 and is adjusted to the required cutting position by means of an inclined cam groove 41 therein engaging a projection 43 on a vertically slidable block 42. A cover plate 36 rests in a groove 37 in the head 22 and is clamped by a screw 39. The block 42 is guided in rectangular slots 44, 46, Fig. 4, in the head 22 and in an enlargement 38 thereon and is moved vertically by a nut 48 engaging the threaded end of a shank 47 on the block. The nut 48 is confined against axial movement between the head 28 and the top of the projection 34 on the head 22. The opposite cutting edges A, B of the cutter are formed parallel and inclined to the axis respectively, as shown in Fig. 5, and an additional cam slot 40 on the opposite side to the slot 41 is provided so that the cutter may be turned end for end to use either cutting edge. The edge A is used when the cylinder has not been worn oval in section to any great extent, whilst the edge B is used to chamfer the upper end of the cylinder and thus avoid ridges when it has been worn considerably oval. The boring-head 22 may be rotated by hand through a rectangular shank 32 on the head or may be rotated by power.

Abstract: 1,002,384. Lasers. PHILLIPS ELECTRICAL INDUSTRIES Ltd. April 30, 1964 [May 3, 1963], No. 18002/64. Heading H3B. A light amplifying system comprises a first semi-conductor laser 1 to which stimulating light from a source 4 is applied, and a second semi-conductor laser 2 which is optically coupled by a lens 3 to receive the output of the first laser; the two lasers being operative only while they are supplied with current from respective pulse sources 5, 6 with the pulses supplied to the second laser lagging with respect to those supplied to the first laser by a time difference substantially equal to the transit time of light between the lasers. In addition the duration of each current pulse is less than double the transit time and the pulse repetition period is at least twice the pulse duration. Consequently any light reflected back from laser 2 to laser 1. cannot be amplified as the latter will not be operative at the time the backwardly-transmitted light is received. The system is therefore unable to go into oscillation. Each of the sources 5, 6 includes a gate, and timing of the pulses is determined by controlling the gates from a transmission line 7 which is connected at one end to a pulse source 8 and is terminated by its characteristic impedance 9.
