Abstract: 1,125,132. Sheet forming. CALMEC EXTRUFORM Ltd. 26 Oct., 1965 [27 Oct., 1964; 17 June, 1965], Nos. 43759/64 and 25680/65. Heading B5A. Hollow articles are made by extruding a sheet of plastics material vertically downwards and drawing it, whilst still hot, by plungerassisted pressure forming, the forming means being mounted upon a carriage which is vertically movable in synchrony with the sheet. The sheet is fed downwards between rolls 8 and 10 and is clamped between two rectangular frames 26, 28, each comprising individual upper and lower frame members, the frames also being mounted upon the movable carriage. The upper individual frame members carry means such that the area of the sheet clamped therebetween is locally cooled in certain regions to ensure that the article subsequently formed is of uniform thickness and that no folding occurs during the forming operation. Whilst an upper area of the sheet is being locally cooled, heated male plungers 30, mounted upon a horizontally reciprocable platen 34 carried by said movable carriage, are forwarded to prestretch the area of the sheet locally cooled in the preceding cycle, the sheet being subsequently sucked on to said plungers. Female dies 32, carried by a similar platen 34, are then forwarded into co-operation with the plungers, the sheet being transferred thereto by a combination of blowing and vacuum. Further closure causes the thus formed articles to be severed from the rest of the sheet after which the plungers and dies are withdrawn the articles being removed from the female dies by a blast of air, and are returned quickly to their upper starting position to initiate another cycle in which a new area of sheet is locally cooled and the previously cooled area formed. Co-operating plunger and female die means for making a flip-lid cigarette packet are illustrated in Fig. 3 (not shown).

Abstract: 1,072,652. Hydraulic transmission of power. EATON YALE & TOWNE Inc. Oct. 27, 1964 [Nov. 1, 1963], No. 43862/64. Heading F2C. [Also in Division G3] In an industrial truck having an engine 13 powering pumps 10, 11, 12 connected through a valve 16 to motors 14, 15 and operated by backpressure in a sump return pipe 24 in such a way that one, two or all three of the pumps feed the motors, backpressure is produced by an adjustable restriction 26 in the return pipe through which low-pressure oil is returned to a sump 17 feeding the pump inputs, oil passing through the restriction and then either through a cooling radiator 29 or directly through a parallel-arranged pipe 30 to the sump. The restriction 26 is adjusted to regulate the relative volume flows through the radiator 29 and the pipe 30, by turning nuts 36, 37 to slide a nozzle 26a along a pipe 27a. The arrangement is such that at low temperatures the high viscosity of the liquid passing through the restriction 26 causes the greater part to return to the sump 17 directly through the pipe 30, thus relieving excess pressure on the radiator 29, but with increasing temperature and decreasing viscosity a greater proportion passes through the radiator. If the capacity of the radiator 29 is such that under high temperature conditions it will accept a greater volume than passes through the restriction 26, then liquid is drawn in through the pipe 30 from the sump 17.
