Title: Improvements in or relating to the extrusion of organic thermoplastic materials
Inventor: CANN JOHNSON RALPH
IPC: B29C48/90
Filed: 1955-02-07
Abstract: 783,449. Extruding thermoplastic tubing. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 30, 1956 [Feb. 7, 1955], No. 3549/55. Class 87(2). Polythene &c. tubing is formed by upward extrusion through a space formed between a die 3 and a core 4, the tubing emerging from the space being forced into contact with the interior of a cooled sizing die 6 by the pressure of cool liquid within the tubing. The liquid is introduced upwardly into the tubing by means of a pipe 9 disposed within the core, and forms a pond which overflows at O into a small pipe 10 disposed within pipe 9. To protect the core from the cooling action of the liquid (a) the tube 9 is lined with or made of heat-insulating material, e.g. compressed asbestos or polytetrafluoroethylene, or is insulated from the core by means of an air space ; (b) a disc 11 of insulating material is disposed on top of the core ; and (c) the core is heated by means 12. The core is centred by screws, one of which is shown at 5. The (brass) sizing die has hollow walls, water entering at 7 and leaving at 8. As shown the internal diameter of the sizing die is greater than that of the extruded tube, but it may be smaller than or equal thereto ; if it is smaller the haul-off rate is greater than the rate of extrusion.

Abstract: 1,216,572. Photographic camera. EASTMAN KODAK CO. Jan.25, 1968 [Jan.27, 1967], No.4010/68. Heading G2A. In a photographic camera, transport means for winding a strip of film from a supply member past an exposure station to a take up member, and for subsequent re-winding, include an operating member driving a power transmitting element, movable between two positions to wind or rewind the film. As shown in Fig.1, in the winding position, clockwise rotation of a winding knob 42, rotates a shaft 33, and film 14 is wound, from a supply cassette 16 past an exposure position 15, on to a take up core 27 rotated by the engagement of a stud 48, on a gear 46 on shaft 33, with a pin 49 on the core. In the rewinding position Fig.2 (not shown) axial movement of knob 42 away from the camera case 11, disengages the stud and pin, but engages gear 46 with gear 24, so that a further clockwise rotation of the knob rotates cassette 16 anti-clockwise, through gear train 46, 24, 23, 19, to rewind the film. The shaft 33 is maintained in either axial position by the engagement of spring-loaded detent balls 38 in groove 39 or 41 in bore 37 of core 27. The winding knob may be replaced by a lever, or the operating member may be power-operated. A sprocket, driven by the operating member may directly move the film.

Title: Improvements in and relating to methods of protecting the tools and the billet during extrusion processes
IPC: B21C23/32
Filed: 1963-02-04
Abstract: In the hot extrusion of metal there is applied between the billet and extrusion tools a lubricant comprising a mixture of at least 0.5% of an oxide or oxides of the metal to be extruded. The mixture may also contain other metal oxides having a greater affinity for oxygen than the extrusion metal oxide and another component which renders the mixture plastically deformable but not viscous or liquid at the extrusion temperature and pressure, whereby the extruded product is coated with the mixture to protect it from oxidation.  When extruding steel, iron oxide is used and may be mixed with sodium tetraborate. Alternatively, for extruding steel at 1100 DEG  C. a metal oxide compound such as FeSiO3 or Fe2SiO4 may be used. Other examples of mixtures are:  Fe2O3, SiO2, Al2O3, Na2O, FeO; Fe2O3, SiO2, Al2O3, K2O, Na2O; Fe2O3, Na2O, B2O3; FeO, SiO2, Fe2O3, MgO, H2O; FeO, SiO2, MgO, H2O; sodium borosilicate and Fe2O3.  The mixture is introduced into the press as a powder, paste or a preformed disc using water glass as a binder.  Powder may be applied to the billet whilst it is being heated and rotated or to the tools by means of a powder flame spraying device.  The coating is removed from the extruded product by stretching or by surface-heating.

The strips may be of paper or synthetic resin. The adhesive may be glue. As shown, strips 2 from rolls 5 (only one shown) are coated on one side by rolls 11 and 12 with adhesive from trough 13. Strips 3 are laid across them mechanically or by band. Strips 4 from rolls 6 (only one shown) are then laid over the strips 2 and the assembly pressed together between rolls 9 and 10.

Abstract: 1,128,163. Dischargers for pyrotechnic devices. SCHERMULY Ltd. 1 Feb., 1966 [2 Feb., 1965], No. 4424/65. Heading F3A. A discharger for a pyrotechnic device is provided with a spring- stressed striker held in a retracted position by a slotted plate and has a firing member 4 attached to or integral with the plate 3, the member 4 being linked to the barrel 1 of the discharger at the end remote from the plate 3 and spaced from the barrel in the region of the plate 3 in such a way that by moving the member 4 in the said region towards the barrel, the plate 3 moves through the distance necessary to release the striker. In Fig. 1 the member 4 is integral with plate 3 and at its free end has an eye-piece secured to brackets 15 by a split-pin 14. Near the plate 3 the member 4 is held away from the barrel 1 by split-pin 16 extending through brackets 17. To fire a rocket or the like, the rocket is placed in barrel 1 and the pin 16 is then removed. By squeezing the member 4 against the barrel, it pivots around pin 14 and forces plate 3 to the release position. The member 4 may be fixed at its free end and is then made of flexible material deforming under pressure to move the plate 3. The movement may alternatively be produced by allowing pivot 14 to ride in slots (23), Fig. 6 (not shown).

Title: Polymerisation process
IPC: C08F297/02
Filed: 1957-02-08
Abstract: Block polymers are produced by polymerizing a polyunsaturated compound containing an ethylenic double bond in conjunction with a second centre of unsaturation represented by the formula: <FORM:0852823/IV(a)/1> in the presence of an active hydrocarbon polymer produced by anionic polymerization of a polyunsaturated hydrocarbon containing an ethylenic double bond in conjugation with a second centre of unsaturation represented by the formula: <FORM:0852823/IV(a)/2> under substantially anhydrous conditions in the absence of oxygen, the polymerizable compound being different from that used in the last previous polymerization step in the production of the active polymer.  Polyunsaturated compounds specified are styrene, alpha-methyl styrene, butadiene, isoprene, 2, 3-dimethyl butadiene, pentadiene-1, 3, cyclopentadiene, methyl acrylate and methacrylate, acryonitrile and methacrylonitrile.  In the anionic polymerization step there may be used the unsaturated hydrocarbons specified above.  The anionmic polymerization may be effected by contacting the unsaturated hydrocarbon with the addition compound of an alkali metal with a polycyclic aromatic compound e.g. naphthalene, anthracene or phenanthrene, the reaction preferably being carried out in a solvent such as tetrahydrofurane, dioxane and dimethyl and diethyl glycol ethers.  The block polymerization reaction occurs when the polyunsaturated compound is added to the anionically polymerized unsaturated hydrocarbon, and when the added compound is itself a hydrocarbon the resulting block polymer is capable of functioning as a promoter for the polymerization of a further polyunsaturated compound.  The following block polymers are described in the examples: (1) polystyrene-polymethyl methacrylate; (2) polyisoprene-polystyrene; (3) polystyrene-polyisoprene; and (4) polybutadiene-polystyrenepolyisoprene.
