Title: Seam-welding of thermoplastic material in sheet or strip form
IPC: B29C65/04
Filed: 1947-05-09
Abstract: 636,747. Seaming non-metallic sheet material. COMMUNICATIONS PATENTS, Ltd., JACKSON, R. D. C., and ZADE, H. P. May 9, 1947, No. 12605. [Class 42 (i)] In seam-welding thermoplastic material in sheet or strip form, a " jig " seam weld is followed, in continuation thereof, by an " uninterrupted " seam weld over such portions of the contour of the seam which are sharply curved or otherwise cannot be conveniently " jig " welded. Apparatus for carrying out this method comprises means serving to intercouple separate " jig " and " uninterrupted " welding means, whereby either of such electrode means can be brought into service alternatively for performing a seamwelding operation. With the apparatus shown, when " jig welding pedal 20 is depressed it causes dog clutch 24 to rotate lever 25, thereby raising rod 26 and lowering upper " jig " electrode 1 towards lower " jig " electrode 2 which is connected via contacts 39, 32 to the output terminal 33 of a high-frequency oscillator 35 energized from a power supply through switch 36. Rotation of lever 25 also closes a switch 43 controlling the high-tension supply for oscillator 35. For " uninterrupted " welding, a lever 8 is rotated clockwise by a handle 10 to (a) connect dog clutch 24 with a lever 28 ; (b) swing electrode 1 back out of the path of an upper roller electrode 3 ; (c) move a shoe 5 carrying " jig " electrode 2 and lower roller electrode 4 so that roller 4 comes beneath roller 3 and contact 40 is connected to contact 32, and (d) move a switch 31 to connect roller 4 to oscillator output terminal 34, and a switch 41 to energize a motor 42 driving roller 4. Depression of pedal 20 now rotates lever 28 to lower roller 3 towards roller 4 and to close a switch 44 similar in action to switch 43. When electrode 1 descends to within a predetermined distance of electrode 2, contacts 46 close to operate a relay 45 which cuts off high-tension supply to oscillator 35 and thereby de-energizes the " jig " electrode system. A similar arrangement may be provided in respect of roller electrodes 3, 4. With the above apparatus, the lines of welding of the two sets of electrodes are in alignment ; as an alternative arrangement, the two sets of electrodes may be spaced apart so that it is necessary to move the material from one zone of operation to another when changing from one manner of welding to the other. According to the Provisional Specification, " uninterrupted " welding means may be arranged as an auxiliary unit to a " jig " welding equipment. Specification 555,054 is referred to.

[Class 64 (ii)] A heating unit adapted for attachment to a vessel such as a food container 1 for heating the contents of the vessel comprises a chamber or cup 2 containing a mass of solid fuel mixture 4 and having means for attaching it externally to the bottom of the vessel, and the solid fuel mixture comprises between 12 and 25 parts of magnesium powder and between 88 and 75 parts of an iron oxide for example Fe2O3 and/or Fe3O4, which may be in the form of mill-scale, which mixture reacts without external air supply at a slow rate and is free from shrinkage in volume during the reaction whereby the reacting mass retains conducting contact with the walls whereby it is enclosed. The cup contains a storm match 5 the head 6 of which is covered by a case 7, and may be attached to the vessel by one or more peripheral grooves or by indentations. A cup as shown in Fig. 5 may be employed with cans high relative to their diameter, and a peripheral step may be provided to facilitate piling. The heating mixture may also include up to 12 parts of aluminium. The Specification as open to inspection under Sect. 91 states that the heating mixture may comprise light metal powder and iron oxide, and also that a substance which does not react, for example excess iron oxide may be included in the mixture to mitigate the violence of the reaction. This subject-matter does not appear in the Specification as accepted.
