Abstract: 1,162,258. Shrink-wrapping. REED PAPER GROUP Ltd. 22 Nov., 1967 [23 Nov., 1966], No. 52498/66. Heading B8C. A package comprises one or more articles wrapped in a heat-shrunk plastics film, a tear strand encircling the articles and being at least partially enclosed within the film, and having part of its length accessible from outside the package so that it may be pulled to tear through the film and thus open the package. In one embodiment, a nylon tear strand 3 is bound around a tray 1 filled with cans 2 and is tied with a slip knot 4. A plastics film 5, formed from two sheets of material and shrunk around the tray and cans, is sealed along two edges 6, openings 7 being left at each of the other sides, through one of which the ends of the strand 3 may be grasped and pulled so that the knot 4 is undone and the strand tears the film between the openings 7 to open the package. Apparatus for forming the package comprises a roller conveyer (1), Fig. 3 (not shown), with either two rolls of packaging film or a single roll of folded material at one end. The tray, filled with cans and tied round with the tear strand, is loaded on to this end of the conveyer between the sheets of film, and the latter are then sealed at each end of the tray by heating-wires (15, 16). The package is then moved along the conveyer to a heating box to shrink the film tightly about the contents. In alternative embodiments, the tear strand may be of cord or wire, and the film material may be completely sealed about the contents with part of the tear strand protruding through a seam. One end of the tear strand may be anchored within the package, and opening 13 then achieved by pulling only on the other accessible end.

Abstract: 1,205,809. Refrigerating. CARRIER CORP. 20 Nov., 1967 [3 Jan., 1967], No. 52667/67. Heading F4H. In an absorption refrigeration system having solution and refrigerant circulating pumps means are provided for maintaining the pumps in operation, after shut-down of the generator, when the solution temperature is above a predetermined value so as to reduce the solution concentration. As shown, the system comprises a direct-fired generator 10, a vapour lift tube 18, a separator 20, a strong solution line 40 leading from the separator to the absorber 47 via liquid heat exchanger 41, a pump 66 for returning weak solution from the absorber to the generator and a pump 36 for recirculating refrigerant from the evaporator sump 34 to spray nozzles 38 in the evaporator. A by-pass line 78 including a solenoid valve 79 leads from the discharge side of pump 36 to the inlet side of pump 66. An electric control circuit (Fig. 2, not shown) includes a switch which when opened normally shuts down the complete system, and a further switch which closes to maintain pumps 36 and 66 in operation when the solution temperature in line 40, as sensed by bulb 1001, exceeds a predetermined value. The further switch opens to complete shut-down of the system when the solution temperature is sufficiently low. During normal operation valve 79 is opened to dilute the solution with refrigerant when the refrigerant in sump 34 is above a predetermined upper level as sensed by a float 81. When the generator is shut down and pumps 36, 66 are still operating, valve 79 is opened when the refrigerent in the sump is above a predetermined lower level as sensed by a float 82. The control circuit is arranged to render float 81 inoperative in these circumstances.

In a stacking apparatus of the type in which articles are added to the base of the stack by being elevated past stack supporting ledges, the ledges are moved clear of the ascending articles automatically by means carried by the elevator. The machine described forms stacks and inserts them into cartons, means, not detailed, being provided to set up collapsed cartons and gum and seal the carton flaps after filling. Belts, as shown, provide sealing pressure while the gum sets. Articles P are fed in by a conveyer 12 to lie on rails 26 above the elevator 30. The stack supporting ledges 37 are mounted on pivoted arms 71, 72 linked to move simultaneously, Fig. 5 (not shown). The arm 71 carries a cam 80 which is engaged by a follower 86 on the elevator to pivot the arms outwards to remove the ledges from the path of the articles , being raised. The cam 80 is mounted on spring- biased linkage 81, 82 so arranged that, on the downward stroke of the elevator, the follower pivots the cam clear and the ledges, returned to their inner positions by a spring 79, support the stack. As the elevator raises two horizontally aligned articles at each stroke, two piles are formed and these are advanced by pushers 34, 35, arranged as shown, to each engage over the height of two articles at different levels. The pushers move in unison and on each stroke, they together move the leading pile of four articles into a carton while the trailing pile of two articles is moved to the leading position.
