Patent GB-635262-A (GB)
Title: Improvements relating to thermoplastic closures for bottles, jars and like containers
IPC: B67B3/02
Filed: 1946-11-07
Abstract: 635,262. Stoppers etc.; applying closure caps to containers. WEBB, E. T. Nov. 7, 1946, No. 33076. [Classes 125 (ii) and 125 (iii)] An organic thermoplastic cap, e.g. of cellulose acetate, for application to a bottle, jar or like container, having an externally screw-threaded mouth, has a flange formed with circumferentially-spaced interior axial ribs and is dimensioned so as to pass freely over the screw-threads on the container. Such a cap is heated to moulding temperature while applied loosely over the container mouth as the container is fed to pressure mechanism which then mechanically presses the top of the cap upon the container mouth, and mechanically applies a constricting pressure about the circumference of the cap flange, such as by an axiallyapplied tapered-throat die, to impress the counterpart of the container thread upon the interior ribs of the cap flange while such is at a moulding temperature. As shown, containers, with caps 3 already in position are fed by hand or by conveyor to a rotating feed table 51, where the caps are heated to moulding temperature (e.g. 170‹-180‹F) by electrical resistance elements 58a mounted in a channel member 58. Each container is then delivered to a spring-supported container rest 27 on a rotary table 25 under a capping head 31 rotating synchronously therewith. Each head 31 includes a pair of coaxial plungers 38, 33, one carrying pressure block 38a and the other a tapered-throat die 35. Engagement of a roller 42b with a stationary cam 9 causes block 38a to engage the top of the cap and compress the lining disc 6, and also causes die 35 to centre on the cap. A roller 43b then engages a stationary cam 10, forcing die 35 down over the skirt 4 of the cap. The tapered throat 36 of the die 35 constricts the skirt 4 and causes an impression of the threads 2 on the container neck to be produced on the circumferentially-spaced ribs 5 which project inwardly from the cap skirt 4. Upon leaving cam 10, roller 43b is raised, by a further cam and the action of a spring housed in a sleeve 32, to retract the die 35, following which roller 42b reaches a rise in cam 9 and the spring raises both die 35 and block 38a clear of the cap. The capped container is then removed by hand, or by star-wheel to a delivery conveyer. The Provisional Specification describes the cap as being pre-heated to moulded temperature before being placed on the container neck.

Title: Apparatus for pressing or consolidating and shaping plastic materials
IPC: A22C7/00
Filed: 1939-12-30
Abstract: 606,174. Hopper and plunger machines. ANTONIETTI, G. Dec. 30, 1939, Nos. 33105 and 33106. Convention dates, March 31, and Sept. 30. [Class 87(ii)] Plastic materials, e.g. meat, are compressed and severed into disc-like shapes in a machine of the hopper and plunger type in which the plunger is given a rotary as well as an axial motion and the hopper is provided with a removable end wall automatically withdrawn laterally to permit removal of the moulded disc and arranged on its return movement to separate the disc from the face of the plunger. A cylindrical hopper 1 is provided with a piston 2 and removable end wall 7. The piston is operated by an electric motor driving a worm wheel 35 through a worm 36, and is moved under a pressure determined by a spring 61 compressed by a four-cornered rod 29 which terminates at its rear end in an extension 30 connected by means of a ball race 31 with a slide 33 sliding within a prismatic guide 34. The drive from the worm wheel 35 is applied to a sleeve 56 mounted on the plunger and carrying a pinion 43 in which travels a pin projecting from the slide 33. The movement of the plunger is thus determined by the cam groove which is shaped to give a slow forward movement a period of rest, and a quick backward movement. The sliding withdrawal of the end wall is controlled correspondingly by a second cam formed on the other side of the disc 44 which actuates a rod 11 and lever 49 having a pin 51 moving in an arcuate slot in the wall 7. A cutting action is imparted to the plunger by notches 64 having cutting edges 65, Fig. 9. Cutters may also be provided on the perimeter of the hopper. The Specification as open to inspection under Sect. 91 describes apparatus in which the piston is rigidly attached to a rod rotated by a pulley engaging in double threaded projections provided on the surface of the rod which also carries a projecting arm which engages with a projection on a rod operating the end wall. Fig. 5 (Cancelled) shows a simpler form in which the meat fibres are compressed in the cylinder 1 by a plunger 2 operated by hand pressure. This subject-matter does not appear in the Specification as accepted.

Title: Shut-off valve for siphons
IPC: F16K1/38
Filed: 1954-11-16
Abstract: 787,585. Siphons; valves. CZERMAK, L. Nov. 16, 1954 [Nov. 21, 1953], No. 33131/54. Classes 69 (1) and 135. A shut-off valve for a siphon comprising a piston 25, Fig. 3, displaceable in a cylinder 24 provided with a suction line 26 through which liquid continuously flows when the valve is opened includes a liquid-carrying tube 1 connected to the piston over which a sleeve valve member 6 slides. As shown inFig. 1, the sleeve 6 is secured to a liner 12 slidable over a mouthpiece 2 secured to the tube 1. The mouthpiece is formed with inclined bores 4 and flexible lips 7, 8, 9 engageable with the liner bore, a further flexible lip 10 being formed on a conical nose-cap 15 secured to the mouthpiece. Stop rings 21, 23 limit the movement of the sleeve in its opening direction and engagement between the mouthpiece and the stop ring 21 limits its movement in the closing direction. When the valve is closed liquid pressure in the tube 1 urges the lips 8, 10 into effective sealing engagement with the liner bore. All parts of the valve may be made of thermoplastic material, e.g. polyvinylchloride and the liner 12 may be made integral with the sleeve 6. Other materials from which the mouthpiece may be made are polyacrylates, other polyamides or similar polycondensates or other highly-elastic and form-retaining plastics such as silicone rubber. In a modification, a mouthring 29, Fig. 2, is secured to the tube 1 and this coacts with flexible lips 9, 10 formed respectively on a nose-cap 15 and an adaptor 38 secured to the sleeve 6. Inclined holes 40 are formed in the adaptor. To open or close the valve the sleeve is first rotated to bring projections 33 thereon into alignment with spaces 34 on projecting rings 31, 32 formed on the tube 1 whence the sleeve may be slid along the tube into its new position and thence again rotated to lock it in this position. The mouthring is formed with an external lip 43 to provide a further seal.

Title: Improvements in or relating to electrolytic processes for the manufacture of beryllium
IPC: C25C3/34
Filed: 1936-12-04
Abstract: 482,468. Electrolytic production of beryllium. GARDNER, D. Dec. 4, 1936, No. 33311. [Class 41] Beryllium is obtained by electrolyzing anhydrous beryllium sulphide dissolved in a fused normal anhydrous fluoride or mixture of anhydrous fluorides, the melting point of which is substantially below 1900‹ C., suitably about 1500‹ C., e.g. in a melt of beryllium fluoride, cryolite, or barium fluoride or a mixture of beryllium and barium fluorides. The electrolysis should be carried out in an atmosphere of a reducing and /or inert gas at ordinary or at a reduced pressure and in absence of moisture, nitrogen and oxygen or oxygen-containing gases, for example in an atmosphere of hydrogen or argon. The electrodes may be of carbon, and the lining of the chamber may be of carborundum or a stable carbide such as zirconium or tungsten carbide, but not of any substance liable to evolve oxygen or oxygen-containing gases at the temperature of electrolysis. If the lining is of carbon (e.g. graphite or petroleum coke), precautions such as increasing the amount of beryllium fluoride are necessary to avoid formation of beryllium carbide. The process may be intermittent or continuous. Specification 482,467, [Group III], is referred to.
