Abstract: 613,473. Coiling. LOCK JOINT PIPE CO. May 14, 1946, No. 14518. Convention date, Oct. 15, 1945. [Class 83 (iv)] In a method of applying a tensioned line, e.g. wire &c., winding to an object such as a pipe core, a loop 19 is formed in the wire between its anchoring point 20 at one end of the object, and a few snubbing turns 17 temporarily applied to the core. A weighted sheave 18 is received in the loop 19 and applies balanced torques to the object so that although the wire is greatly tensioned the power required to rotate the object is low. The sheave 18 and a wire guide 16 are traversed longitudinally as the core is rotated to apply the main winding 29. The movement is stopped when the snubbing turns 17 run on to a mandrel or chuck face at the other end of the pipe and the wire is anchored to the pipe at this end. Specification 582,553 is referred to.

Title: Improvements in and relating to thermo-plastic materials
IPC: C04B28/36
Filed: 1930-05-14
Abstract: A thermoplastic material is made by heating selenium sulphide with a filler and then subsequently converting the mass to a hard dense product as for example by pressing and subsequently heating. The filler may be admixed with selenium and sulphur and then fused with subsequent conversion to a hard dense product.  The filler may be asbestine, slate, iron oxide, talcum, clay, marble dust, ground flint, black natural slate such as keystone filler or diatomaceous earth, wood flour, mica, &c.  In an example selenium sulphide is fused with such a filler at about 125 DEG  C., cooled down, pressed cold and then cured for about half an hour at 80-90 DEG C.  By heating this dense product at about 105-115 DEG  C. it becomes soft and plastic again.  The selenium sulphide may be used as a binder for cloth and paper.  In an example a suspension of SeS2 and Fe2O3 in denatured alcohol is painted on cloth or paper which, after evaporation of the solvent is pressed up at about 125 DEG  C. and then cured.  The product is useful for gears, insulating material, &c.  To make an acid-proof coating on, for example iron, a suspension of the selenium sulphide and filler or the selenium sulphide fused in with the filler is sprayed thereon, the volatile suspension medium is evaporated and the surface heated to about 105-115 DEG  C. and then cured for about half an hour at 80-90 DEG  C.ALSO:A thermoplastic material is made by heating selenium sulphide with a filler and then subsequently converting the mass to a hard dense product as for example by pressing and subsequently heating.

IPC: B65B43/42
Filed: 1958-05-09
Abstract: 875,810. Discharging pleated cups from a stack. FORGROVE MACHINERY CO. Ltd. April 16, 1959 [May 9, 1958], No. 14936/58. Class 117 A slide 22 (Fig. 1) which carries a separating head 30 and a suction member 21, is reciprocated in the vertical plane by handle 25 so that the head and members together effect the separation and discharge of the innermost cup of stack 18. Thus the stack 18 of pleated cups is contained in cavity 16 formed in foamed plastic layer 14 carried by a second slide 11 which may be displaced rightwards by handle 12. Head 30 is rotated at 33 by a motor carried by slide 22. Suction member 21 is supplied by suction at 43 and controlled manually at 44. The sequence of operations is as follows:- the operator depresses handle 25 to lower head 30 into the stack so that the rotation of the head frees the innermost cup. The operator then elevates handle 25 to raise head 30 and displaces stack 18 to the right so that, when he again depresses handle 25, the suction member 21 grips the freed inner cup for subsequent removal as in Fig. 1. Alternatively, the freeing may be by means of arms 49, Fig. 10, carried by rotating spindle 31 (see Fig. 1) so that, when the arms are pressed downwards against the innermost cup, the downward movement of cam 48 causes the arms to move inwards and to pucker and thus free the innermost cup.
