Abstract: 1,101,756. Thermoplastic containers. U.M.P. VENESTA Ltd. 17 Aug., 1966 [17 Aug., 1965], No. 35194/65. Heading B8D. [Also in Division B5] A rigid or semi-rigid tubular container is made by pressing the open end of a body tube 7 of thermoplastic material against a sheet 9 of thermoplastic material, rotating the tube 7 about its axis so that frictional heat is generated and the tube 7 is caused to shear into the sheet 9 to sever a disc 12 therefrom and then, while holding the disc within the end portion of the tube 7, supplying or generating sufficient additional heat to cause the disc 12 to fuse to the tube 7 to form an end closure thereto. The pre-cut tube 7, Fig. 1, is positioned on a spindle, projecting from a turret 4, at a position C and is held near its inner end by a split collar 6 with the outer end of the tube projecting beyond the end of the spindle. The turret 4 is indexed through 90 degrees to bring this spindle to a position D. A tubular outer portion 5 of the spindle is rotated at a preset speed and, simultaneously, the spindle moves to the left of Fig. 1 to press the end surface of the tube 7 against the sheet 9 which is held against rotation and pressed towards the spindle by a friction pad 10 urged by springs 11, a non-rotating inner member 8 of the spindle being provided with a cross-hatched or scored outer end to help grip the sheet 9. The disc 12 is severed from the sheet 9 and the spindle 5 whilst still rotating continues to move forward carrying the disc 12 and additional frictional heat is supplied. The spindle is stopped and the disc 12 becomes welded to the tube 7. The spindle is indexed through a further 90 degrees to the position A and the completed container removed. In a modification, Fig. 3, the surface of the pad 10 is formed with an annular groove and the disc 12 is set inwardly from the end of the tube 7 so that its terminal portion 13 is flanged inwardly and fused against the outer face of the disc 12. In another modification (not shown), the required relative movements are produced by moving the base towards and away from the stationary spindle. In further modifications (not shown), the additional heat to effect welding of the disc to the tube is applied by hot tools or by dielectric heating. The tube and the disc may be made of the same or different thermoplastic materials but preferably the tube 7 is of higher melting point than the disc 12. Specified thermoplastic materials are high density polyethylene, polyvinyl chloride, polyacetyl, polypropylene and pclystyrene.

Abstract: 1,105,216. Measuring total load conveyed. MERRICK SCALE MFG. CO. 8 Aug., 1966, No. 35493/66. Heading G4H. An apparatus for measuring the total load carried on a member, e.g. a conveyer belt, moving at a variable speed, pulses induced in an induction coil 127 (Fig. 14) as a wheel 107 rotates at a speed proportional to the speed of the belt are accumulated in a counter 145 when a contact 105 is closed. The contact 105 is controlled by an induction coil 81 which moves axially in front of a rotating annulus with triangular teeth 70 in accordance with the weight of the loaded belt and which closes the contact 105 when it is adjacent an air gap between the teeth and opens the contact when it is adjacent the base 71 of the annulus or the teeth 70. Consequently the time during which the contact 105 is closed is proportional to the load on the conveyer belt. In the embodiment described a scale beam 59 (Fig. 2) is deflected in proportion to the load carried on the belt by a spring 64 and this movement is transmitted to the induction coil 81 (see Fig. 12). The position of the coil may be adjusted with the conveyer belt running empty until a predetermined count per unit time for a given conveyer belt speed is registered in the counter. The wheel 107 is rotated at a speed proportional to the speed of travel of the conveyer belt by a gear wheel 117 linked, via a gear 121 and a sprocket chain 125 to the shaft of a pulley 20 (Fig. 2) round which the conveyer belt is driven.
