Title: Splicing apparatus
Inventor: COLE ROBERT EUGENE
IPC: C09J5/00
Filed: 1968-08-23
Abstract: 1,243,342. Film splicing. EASTMAN KODAK CO. Aug.23, 1968 [Aug.23, 1967], No.40348/68. Heading G2C. A strip-splicing device comprises a pair of strip support tables movable towards and away from each other by drive means, a cutter for trimming the ends of the strips when the tables are apart and an applicator for applying tape to abutting ends of the strips when the tables are together. As shown, the cutter comprises a handle 45 which is depressed so that blades 48, 49 thereon trim film strips 10, 11 supported by tables T, T<SP>1</SP>; a sprocket-hole punch 53 also being depressed. The handle is returned by springs 56 and (55), Fig.1, (not shown) and closes a switch 57 of a motor (58) which drives the tables together through a pinion 63 and racks 62, 66; the handle and tables being mounted on a rod 20. The motor (58) has a slip clutch (61), Fig.5, (not shown) and continues to run when the tables meet. As the tables meet, the rack 62 engages a switch arm 77 of a motor 79 which drives, through levers 86, 87, 88, 95, a tape applicator comprising carriages K, R, which move perpendicularly to the direction of table movement to apply tape from a roll 104 to abutting ends of the strips; as described in Specification 1,243,343. When the tape carriages K, R have returned to their original positions, a cam 113 driven by motor 79 operates a switch 114 to reverse the direction of table drive and consequently to switch off motor 79. The tables are driven apart until rack 66 engages a switch 116 which stops the motor (58) and may connect a film take-up circuit, Fig. 9, (not shown).

Abstract: 1405672 Kneading plastics material L WITTROCK 31 Aug 1972 [2 Sept 1971] 40410/72 Heading B1C [Also in Division B5] Thermoplastics material is kneaded and plasticised solely by frictional heat in means 5, which has substantially no conveying action and is fed by means 1 and discharged by means 9; the speeds of the means 1, 5, 9 are independently controllable and the temperature in the plasticiser is controlled by regulating the pressure therein by varying the relative speeds of the feeding and discharging means. As shown the plasticiser is a rotor 6 having projections 7 and the feeding and discharging means are each a pair of intermeshing conical three-start screws 2, 3 and 10, 11; the screw cores have a greater taper than the envelope so that the capacity of the screws is constant or increases in the conveying direction. The feeding, plasticising and discharging means are each separately controllable by variable transmissions 18, 19, 20. The temperature in the plasticiser may be monitored by a sensor 27 and adjustment of the plasticising pressure may be effected automatically. The plasticiser may alternatively be a cone, wheel, disc, screw or planetary roller device. The discharging means also compresses the material and supplies it to an extension orifice 21 for forming a hollow shape.

Title: Containers formed of foamed thermoplastic materials
IPC: B29C44/02
Filed: 1964-10-15
Abstract: A foam thermoplastic resin sheet or tube is chilled on at least one surface, as it emerges from an extruder, to produce an integral skin, the foam resin comprising at least 50% of the total thickness of foam resin and skin.  Many examples of thermoplastic materials are given, including polymers and copolymers of vinyl compounds, particularly polystyrene, as well as chlorinated rubber, cellulose ethers and esters, polycarbonates, polyesters, polyethers and polyurethanes. A nucleating agent may be used comprising ammonium, alkali and alkaline earth carbonates or bicarbonates, with an acid or acid-reacting salt. A wetting agent may be added. The thermoplastic polymer may be pre-mixed in pelletized form with an absorbent, e.g. diatomaceous earth, in which is incorporated a volatile liquid, e.g. an aliphatic hydrocarbon, which is non-reactive with the polymer.  Thereafter the material is formed into a sheet or tube by hot extrusion.  The sheet may be vacuum-drawn into cups the open ends of which are joined by spin-welding (see Division B5) to form containers (see Division B8).ALSO:An infant's feeding bottle, Fig. 4 (not shown), is formed from foam plastics having inner and outer non-formed skins, produced by chilling the plastics tube or sheet (see Division B8) from which the bottle is made.  The teat is formed integrally with the bottle. The bottle is vacuum-formed in two halves which are joined by spinwelding (see Division B5).  After filling through the teat end, the bottle is sealed with a sterile metal foil cap, a hot fluid wax, or a heat shrunk plastics film.

Abstract: 1,055,139. Helical scan record tape systems. AMPEX CORPORATION. Oct. 5, 1965 [June 17, 1965], No. 42154/65. Heading G5R. In a domestic television recorder, the lower drum 18 is fixed, while the upper, carrying the head 21 is rotated against the direction of feed of a magnetic tape 14. Tape moving relatively to the upper drum 19 is air-spaced therefrom by air swept in by the drum between the guides 24, 26 at the tapeexit point. The head 21, while bearing on the tape, Fig. 6, raises a moving " tent " region. At 37 air is sucked in from the clearance gap between the drums and at 39 is trapped and squeezed between the tape and lower drum 18, at 41 to air-space the tape therefrom. In a modification (Fig. 4, not shown), the drum 19, besides the head 21, carries one or more passive tape-contacting members, since the amount of protrusion of the head 21 for good record/playback performance may be insufficient for good air-bearing performance at the lower drum 18. The arrangement may also be applied to 180-degrees wrap systems. The tape is guided into and out of the helical path on to the reels by conical guides (Fig. 1, not shown).

In a variable speed friction gear of the kind described in the parent Specification wherein discs 3, 4 on input and output shafts 1, 2 project between a pair of discs 6, 7 on another shaft 5 inclined to the input and output shafts 1, 2 to form V-shaped gaps between the discs into which friction rollers 8 are urged to make friction driving contact between the discs, the disc 6 is mounted on the shaft 5 for limited relative rotation and balls 16 between cams 15, 13 on a hub 14 fast with the shaft 5 and disc 6 urge the latter towards the disc 7 during said relative rotation. During torque transmission the roller 8 on one side of the disc 3 is urged into the V- gap whilst the roller on the other side of the disc is urged away from the V-gap which due to elasticity of the parts tends to drive the discs 6, 7 at slightly different ratios whereupon the relative rotation between the shaft 5 and disc 6 urges the latter towards the disc 7 and thus forces the rollers back to the correct position.

Abstract: 1521258 Dispersing gases in liquids IMPERIAL CHEMICAL INDUSTRIES Ltd 19 Sept 1975 [3 Oct 1974 8 Jan 1975 13 March 1975] 42923/74 763/75 and 10456/75 Heading B1C [Also in Division Cl] A gaseous liquid containing biologically degradable material in solution and/or suspension is treated with an oxygen-containing gas, and a culture of microorganisms is maintained therein. For a period of time not greater than 5 minutes the liquid is subjected to a low DOT of less than 30 millibars, and/or for a period of time not greater than 10 minutes the liquid is subjected to a high DOT of at least 450 millibars. In this way the ratio of carbon dioxide to cellular material produced by the culture is increased during the process. There is also a period during which the liquid is subjected to DOT between 30 and 450 millibars. The microorganisms are not detrimentally affected by this treatment. The term DOT means dissolved oxygen tension i.e. partial pressure of oxygen in the liquid. This process is useful as a stage in the biological treatment of sewage as described in U.K. Specification 1473665. In Fig. 6 a downcomer (14) and riser (15) are located in the same shaft A-A, separated by partition (23). The upper ends of partition and downcomer are bent over within basin (13) to give deflectors (25) which produce a circulation as indicated by the arrows. Initially air is injected into the riser via sparger (17) in order to start the air lift, but the bulk of the air may subsequently be fed to the downcomer via sparger (16) while the whole system continues to function as an air lift pump.
