Title: Band sealer for closing bags
IPC: B29C65/00
Filed: 1975-06-26
Abstract: 1476263 Seaming non-metallic sheet material DOMAIN INDUSTRIES Inc 26 June 1975 [13 Feb 1975] 27128/75 Heading B5K [Also in Division B8] A machine for closing and sealing bags by welding together film layers at the top of the bag comprises a pair of endless conveyer chains 17 having co-operating confronting bag-conveying runs 17a; a pair of endless heating bands 28 mounted above the chains 17 and having confronting film-heating runs 28a along which lie heating bars 30 to supply welding heat thereto, spring means 33 urging the runs 28a towards the film layers; and a pair of endless cooling bands 35 mounted above the chains 17 and having confronting film-cooling runs 35a and band-cooling bars 37. As shown, the runs 17a of the chains 17 extend along a bag top-receiving slot 15 formed between base plates 14, spring pressed guides 20 maintaining the runs 17a in predetermined spacing. The bands 28 are trained around mounting wheels 29, 29.1, the wheels 29 being offset relative to the wheels 29.1 to facilitate accommodation of bags of different thicknesses. Similarly, the bands 35 are trained around offset wheels 36, 36.1. The bands 28 each comprise a continuous strip of heat conducting material, e.g. steel, or fibre glass and are coated with a release agent, e.g. polytetrafluoroethylene. The bars 30 are heated by internal resistance heaters and are pressed against the runs 28a by springs 33 the pressure of each of which is adjustable by a device 34. If it is desired to produce a double seal at the top of each bag, the bars 30 are formed with dual heating faces. The cooling bands 35 may be continuous and constructed of heat conducting material, e.g. steel, or may be discontinuous and comprise individual plates 35.1, Fig. 8, carried on roller chains 35.2. Cooling bars 37 are urged against the runs 35a by springs 38 adjustable by devices 39. The bars 37 are cooled by the circulation therethrough of cooling liquid, e.g. tap water. Alternatively, the bars 37 are located along the return runs of the bands 35 rather than along the runs 35a. Guides 51 may be disposed between the bands 28 and the bands 35. The bags may be made of polyethylene and the seal 5, Fig. 5, may be a shrink seal having an area substantially thicker than either of the layers L 1 , L 2  from which it is formed.

Abstract: 1306697 Injection nozzle K AOKI 5 June 1970 [7 June 1969 29 Dec 1969] 2752/70 Heading B5A An injection nozzle 2, heated by heater 20 and engaged during injection with an inlet bushing 24 of a mould 5, includes a through passageway 3 within which a closure rod 4 is longitudinally reciprocable from an open position (shown in Fig. 1) to a closure position (shown in Fig. 2) in which the rod projects through the end of the nozzle and engages the inner surface 7 of the bushing. The rod is reciprocated by a lever 14, pivoted at one end to a slide 9 which is located in a housing 11 which projects into the passageway 3 and to which the rear end of the member is fixed. The lever is pivoted at its other end to the piston-rod 17 of a piston-andcylinder mechanism 16, 19 mounted upon the nozzle housing between plates 23. When the rod 4 is in its closure position, its flat front face is level with the inner surface of the mould cavity thereby eliminating any sprue. In a second embodiment the member may stop short of the mould surface thus allowing a sprue of reduced length to be formed.

Class 98(1) In an X-ray cassette a number of films are arranged one behind the other, spaced apart and parallel, and separated by layers consisting throughout of readily deformable resilient material, transparent to X- rays. As shown in Fig. 1, a box 1 has a hinged lid 2 with spring fasteners 3, 4 and receives an insert 5 which, as shown in Fig. 2, consists of a number of sheets 6 of resilient material bound together like the leaves of a book. Sheets 6a carrying intensifier layers may be bound with the sheets 6 and outer layers 8, 9 of e.g. balsa wood may act as book covers. The sheets 6 may be of foamed rubber with a slippery coating such as textile fabric. When the box 1 is closed with the insert 5 inside, the sheets are pressed together by the lid 2, which may bear on a pad 15 of foamed rubber, felt or the like, the films being placed between adjacent sheets 6 or sheets 6, 6a. The sheets may be slotted to achieve uniform pressure. Straps 11, 12 fixed to the covers 8, 9 prevent the book-like insert from opening completely, and also form loops 13, 14 when the insert is in the box to facilitate removal. To reduce X-ray reflection, a lead foil, e.g. 0.5mm. thick, is inserted behind the last film. The sheets may be bound in book form by threading them on rigid or flexible members. Either the lid or the base of the box may have means for retaining it in X-ray tomographic apparatus, in a position centred upon the central beam of the X-ray source.
