Title: Improvements in and relating to oxidation products of rubber
IPC: C08C19/08
Filed: 1935-12-24
Abstract: Rubber derivatives are prepared by adding an oxidizing catalyst, e.g. cobalt linoleate, to rubber and oxidizing or depolymerizing the rubber by mixing therewith a large quantity of powdered, granular or porous inert material and working the mixture in oxygen or air; the inert material enables a larger surface area of the rubber to be exposed to oxygen or air.  Inert materials specified are wood flour, silica flour, kieselguhr, and powdered asbestos; examples refer to the addition of 100-230 parts of wood flour to 100 parts of rubber. The reaction is accelerated by raising the temperature and is preferably carried out at 80-85 DEG  C.  It is stated that according to the degree of oxidation three different resinous products may be obtained varying in their solubility in white spirit, alcohol and acetone; the degree of oxidation may be increased by increasing the proportion of wood flour used and by milling the rubber in air prior to the addition of the catalyst.  The rubber derivatives prepared according to the invention may be used for varnishes or for moulding purposes with or without other thermo-setting resins, e.g. condensation products of formaldehyde with phenol, urea or thiourea or of glycerol with phthalic anhydride.  Specifications 417,912 and 462,613 are referred to.

Title: Process and apparatus for the manufacture of thermoplastic films
IPC: B29C55/10
Filed: 1956-12-03
Abstract: <PICT:0849466/IV(a)/1> A tube of artificial thermoplastic material capable of being orientated is "distended" to form a tube of larger diameter while the zone of transition between the narrower and wider portions of the tube is in an elastic state and at a temperature within a range extending from the softening point or crystallite melting point of the thermoplastic material to 60 DEG C. below this point and in such manner that the said zone is "distended" by the application of an internal pressure to cause orientation in all directions, and the wider portion of the tube is maintained in its distended state while being cooled to set the orientation. "Distended" is defined as being stretched beyond the upper stretch limit and is characterised by local necking constituting a flow spot limited to a very restricted area determining the new distended cross-section.  The tube of artificial thermoplastic material may be distended by internal pressure against the inner wall of a hollow guide member such that the tube is cooled while in contact with the guide member.  As shown in Fig. 7 apparatus for carrying out the process of the invention may comprise heating means, e.g. copper guide tube 2 surrounded by heating bath 3, means for creating a pressure within the tube, e.g. compressed air, hollow guide member 6 for cooling the tube and tube advancing means.  Specified artificial thermoplastic materials are polymers and copolymers of vinyl chloride, trifluorchlorethylene, ethylene and propylene.  If desired, after subjection of the tube of artificial thermoplastic material to distention, it may be axially stretched at a lower temperature.  The distending may be carried out in stages at different temperatures falling within the range defined above and cooling the tube may be achieved by use of an annular stream of cool fluid.  Examples are given.  Specifications 799,392, 799,823, and 801,031 are referred to.

Title: Improvements in or relating to hydraulic spacing tables
IPC: B23Q5/36
Filed: 1959-11-02
Abstract: 938,422. Drilling; machine tool details. S. H. HOLMES. Nov. 2, 1959 [Nov. 7, 1958], No. 37144/59. Class 83 (3) A table assembly for a milling or a drilling machine comprises an hydraulic motor 15 for moving a slide 11 and an abutment 58a contactable by the table to control a valve 17 in the line to the motor. A table 12 is moved by hydraulic means 16 on the slide 11. The valve 17 controlling the hydraulic means 15 for the slide 11 is biased by oppositely-acting springs which are adjustable. The stronger spring 53 acts through a bar 58 carrying equally spaced abutments 58a. To cause movement of the slide to the right, a lever 75 is moved counter-clockwise causing a cam 76 thereon to raise a cam bar and lift a dog 72 on the slide 11. When the next desired abutment is approached, the operator releases the lever 75 and the dog 72 engages an abutment and causes centring of the valve. For opposite movement, the lever 75 is moved clockwise and a cam 78 moves the bar 58 to overcome the force of the spring 53. A rack 84 on the base 10 causes rotation of gearing 83, 82 so that movement is indicated on a dial 80. To adjust the table by a fraction of the distance between abutments 58a the dog 72 is carried on a slide 71 which can be manually adjusted by a screw 86 for a distance indicated on a dial 87. The dial 87 may be zeroed by a screw 89. The table 12 is adjusted in a similar way. The abutments on the bar 58 may be nuts and the bar may have several sets of abutments which can be indexed into position by angular adjustment of the bar. In a modification, the valve 17, Fig. 5, is contacted by a threaded member 111  which is rotated by a drive 112. The member 111 engages a nut member 173 on the table 113  so that the valve is caused to control the motor 114 in such a way as to maintain the movement of the table equal to the relative movement between the nut and screw 173, 111. Specification 938,423 is referred to.

Abstract: 1371274 Seaming non-metallic sheet material IKEGAI TEKKO KK 9 Aug 1972 [9 Aug 1971] 37149/72 Heading B5K [Also in Division B8] A strapping machine comprises a press member incorporating a heater to soften a plastics band to be joined while pressing two parts of the band uniformly the press member being oscillatably mounted on a base section of the machine. As shown, a package a is strapped with a band b of plastics material which is drawn from a reel 15 and the free ends of the strap are welded under heat and pressure before separation from the material on the reel. The strapping material is fed from the reel through a passage 26 on a press member 23 by operation of a lever 16 and is passed by hand over a clip 58 beneath a table 52 to anchor the free end of the material by further operation of the lever 16. The feed of the material is continued to form a loop over the table 52, into which the package a is then placed. Further operation of the lever 16 then causes the direction of feed to tighten the material about the package after which the reel is clamped by a magnetic brake 21 on its shaft. A motor (36), Fig. 6A (not shown), is then started by operation of a switch (82) in an electric circuit, Fig. 10 (not shown), to move the press-member 23 anticlockwise to disengage the band b from a groove 24 on the press-member, Fig. 13, which raises a lever 43 carried by the press-member so that a heater 37 carried on the lever 43 is applied to the two sections b<SP>1</SP> and b<SP>11</SP> of the band which are then pressed together by a press surface 25 of the press-member 23. As the press-member reaches the end of its travel, a lever (61) which is oscillated by a cam (35) driven by the motor (36), releases the clip 58 and the table 52 from the loop, which action temporarily increases the tension in the band causing it to break off close to the sealed sections. The press member then moves back to its original position and the other parts return to their original positions.
