Abstract

1337698 Boxes for tape cassettes SEILIB 21 June 1972 29098/72 Heading B8P A box for tape cassettes comprises two box elements 1 connected by a hinge 2, each box element 1 having ribs 3 which are spaced apart by a distance slightly greater than the thickness of a mini-cassette on two opposing side walls and ribs 4 which are spaced apart by a distance slightly greater than the thickness of a longperiod cassette on the other two side walls. The height h of each box element 1 is equal to the height of the cassettes. A resilient mat 5 is located at the bottom of each box element to raise the cassettes when the box is open and to urge the cassette in the two box elements into contact when the box is closed. The box is held closed by two identical semi-circular latches 6. The ribs 3, 4 may have grooves to locate partitions 11. The box may have an articulated handle or a tassel for gripping. A number of boxes may be placed in the open condition in a carrying tray (8) which has suspension lugs (9). 1337725 Unloading liquid cargoes EMCO WHEATON UK Ltd 12 Jan 1971 [9 Jan 1970] 1280/70 Heading B8E In a device for unloading liquids, the liquid flows through articulated pipes 15, 18, 16 which form a parallelogram linkage with a supporting jib 12 and this arrangement provides some counter-balancing for the pipe 13 to counteract the effect of the liquid therein. Additional counter-balancing may be provided by pumping liquid, e.g. water, in and out of the hollow jib 12 as required so that the apparatus is counterbalanced in both the "dry" and "wet" conditions. Weights 10 balance the jib 12 and weights 25 may be provided if required. Supports 3 for the upright pipe 1 are compensated for expansion by having liquid flowing through them. Gases from the vessel being filled pass through a hose 29. The jib turns about a vertical axis at 6.
