Title: Improvements in the heat-sealing of thermoplastic film
Inventor: GATES WILLIAM ELLIOTT FREW
IPC: B31B19/64
Filed: 1952-08-13
Abstract: 740,811. Seaming non-metallic sheet material. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Aug. 12, 1953 [Aug. 13, 1952], No. 20341/52. Class 42 (1). [Also in Group XVII] In a process for forming transverse seams between two or more continuous, superimposed layers of thermoplastic film by passing them from a feed roller or rollers over a supporting plate or drum to a take-off roller or the like and bringing a heated seaming member, protected by a separating barrier, into contact with the film above the plate or drum and holding it there until the layers are seamed together across their width, at least one securing member is brought into contact with the film close to the seaming region, and on each side thereof, before the heat-sealing member is withdrawn from contact with the film, and is withdrawn from contact with the film after the heat-sealing member has been withdrawn, the seaming member or members being at a temperature below the heat-sealing temperature of the film. As shown, flattened tubular film 1 passes from a feed roller 2 to take-off rollers 3 over a supporting metal plate 4 surfaced with resilient silicone rubber 7. The feed of the film is interrupted at set intervals, and an electricallyheated metal sealing strip 5 and a securing member 6 are brought down simultaneously, under spring loading, to press the film against plate 4. The edge of strip 5 is coated with polytetrafluorethylene to form a separating barrier. Member 6 extends on each side of strip 5 across the width of the film and is preferably water-cooled. When a heat-seal has been formed, strip 5 and member 6 are raised successively and the film advanced for the next seal. In an alternative arrangement, plate 4 is replaced by a continuously revolving drum, surfaced with silicone rubber, around a part of whose circumference the film passes. The sealing and securing members are adapted to press the film on to the drum surface, to travel for a short distance with the drum to seal the film, to be raised in succession and to be returned to their initial positions for the next sealing cycle. For sealing polythene film, a sealing-strip temperature of 180‹ C. is used and the sealing and securirig members contact the film for 0.5 and 0.8 seconds respectively.

Abstract: 689,650. Drying apparatus. HARRISON, J. Aug. 10, 1951 [Aug. 21, 1950], No. 20677/50. Class 34 (ii) Apparatus for drying grass &c. has a chamber 18 open at the top and horizontal rails 19 on which containers 11, having open work tops and bottoms 16, are supported by central wheel supports 15 to form a ceiling to the chamber 18 so that drying gas ascending from the chamber passes through the grass, the containers 11 being transported along the rails on the wheel 15 and being rotatable about the wheels to reverse the position of the container. Heated air is passed into the chamber 18 through a pipe 22 by a fan 23 via a manifold 24 having control valves 25. In a modified form of chamber, a central partition provides two subchambers having separate supplies of air and in another modification one subchamber has a hood to enable the drying gas to be returned for re-circulation. In a further modification (Fig. 7) a central partition 26 is fixed and a movable partition 32 provides sub-chambers 33, 34. Wet grass is placed above chamber 34 and some of the air from chamber 27 is recirculated through chamber 33, the remainder passing through the wet grass over chamber 34 and thence to the atmosphere. The containers 11 have opposite side walls 12, 1, each provided with a pair or coacting hinged flaps 13, through which the containers are loaded or unloaded.

Abstract: 717,420. Water-tube steam boilers; regulating superheat. BABCOCK & WILCOX, Ltd. Sept. 3, 1952 [Sept. 5, 1951], No. 21004/51. Classes 123(2) and 123(3)  In a steam boiler comprising parallel gas paths 2, 3, Fig. 1, which lead from a combustion chamber 1 and locate, the pass 2, a bank of steamgenerating  tubes 7 screened by a tube bank 6 and, the pass 3, a steam-generating tube bank 10 with a screening bank 8 and intermediate superheater 9, the tubes 6, 7, 8, 10 extending, for example, between an upper steam- and-water drum (not shown) and lower water drums on opposite sides of the. chamber 1, the superheat temperature is controlled by a swinging damper 13 which is disposed in a gas pass 5 subsequent to the passes 2, 3 and is adapted differentially to vary the gas flows through the latter passes. The pass 5, which houses an economizer 4, is divided into separate passages by parallel baffles 14-18 with any one of which the damper 13 is adapted to coact. A second or auxiliary damper 27, which normally lies against a wall of the pass 5, may be provided for independently varying relative gas quantities flowing through the passes 2, 3, and, preferably, the two dampers are so arranged that they may be brought into alignment to prevent gas flow through the superheater pass 3 when starting up the boiler. In the practical embodiment of Fig. 4, the parallel gas paths 2, 3 (not shown) lead to spaces 64, 66 above the front and rear parts respectively of the upper steam-and-water drum 50. An economizer 61 extends above the spaces 64, 66, the gas flow through the lower part of the economizer being subdivided into fourteen gas passages by thirteen vertical baffles 86-89 with which co-operates a swinging damper 81. Similarly the flow through the upper part is subdivided by fourteen baffles 115-128 which are staggered with respect to the lower baffles and have associated dampers as shown, said dampers being operated simultaneously so that each coacts with one or the other of the baffles on the two sides of the pivoting axis thereof.
