Title: Orienting and feeding articles
Inventor: BERGLUND JAN
IPC: B65G47/14
Filed: 1983-01-05
Abstract: Apparatus for orienting and feeding articles 1, in particular closure cap blanks of the type having a disc- like panel 1b, surrounded by a skirt terminating in a free edge from which a gripping tag or ring 1a extends, wherein the closure cap blanks 1 are randomly deposited on a carrying surface formed by the interior of a rotating drum, or the surface of an endless conveyor belt 18; and are held in contact with that carrying surface magnetically by means of magnetic strips 22 underlying the carrying surface The caps engaged with the carrying surface are conveyed by rotation of the drum or advancement of the conveyor and are subjected to a force tending to dislodge them, such as the force of gravity or the force of an air jet. Closure cap blanks retained with their top surfaces 1b, against said carrying surface are held more firmly than blanks disposed in other orientations and are thus retained on the carrying surface whilst other blanks are dislodged and returned for resorting. A guide member spaced from the carrying surface entrains the blanks by their gripping tags or rings 1a as the blanks are conveyed past the guide member, to arrange the blanks in a row with a common desired orientation. <IMAGE>

Patent GB-2123913-A (GB)
Title: Quick-release couplings
Inventor: LUNDBERG CARL MAGNUS
IPC: F16L37/23
Filed: 1983-06-28
Abstract: A quick-release coupling for a pressurized medium network, having a male coupling half (3) and a female coupling half (4) with an exterior, axially movable latch release member (6) on the female half activating a latch member in a normal position to prevent the insertion of the male half (3) into the female half (4), as well as its removal therefrom and in a retracted position disabling said latch member, such that the male half can be moved into the female half or removed from it. The arrangement has support members (8, 15) for the male and female halves (3, 4). At least one support member (8) is movable for providing a relative axial movement between male and female halves. A retracting member (10) can move the latch release member (6) to its separated position and is resilient via spring 9, when the male and female halves (3, 4) are completely mated. The retracting member (10) and both halves (3, 4) can be given a mutual axial latching movement causing the retracting member to assume a position in which it allows or causes, the latch release member (6) to assume its normal position. They can also be given the opposite mutual movement, whereby the retracting member, at least temporarily, moves the latch release member to its retracted position. <IMAGE>

Title: A process for the preparation of fatty substances
Inventor: TRAITLER HELMUT
IPC: C11B1/10
Filed: 1983-10-14
Abstract: The oil of pips of fruits of the Ribes genus is an abundant, cheap source of  gamma -linolenic acid. It is extracted by pressing, or by using solvents, from dried and ground residues from the production of juices, preserves and jellies or brandies, liqueurs and schnapps of fruits, such as blackcurrant, redcurrant or gooseberry. The residues may be treated with a polar solvent, before being extracted with a non-polar solvent or supercritical fluid, in order to free the oil from most of the free fatty acids, waxes, colourings and odorous compounds. A preferred embodiment comprises flaking the washed pips and protecting them against oxidation before pressing the flakes prior to solvent extraction. The refined oil is a valuable ingredient in cosmetic, dermatological, dietetic and pharmaceutical compositions.

Title: Tissue dispenser
Inventor: PAINTER HARRY
IPC: A47K10/42
Filed: 1984-11-08
Abstract: A dispenser for tissues, paper towels, medical wipes, serviettes and the like comprises a container, which is approximately an open-topped cube with an opening 6 at the front. Tissues are placed in the container interleaved in a stack with their edges accessible through the opening 6. A plate 10 is then placed on top of the stack. Whenever the uppermost tissue is pulled out of the container it draws the next tissue part of the way out so that at any time the uppermost tissue sticks through the opening ready to be grasped. The plate 10 keeps the stack neatly pressed down and enhances friction between the top two tissues which assists in providing that pulling out the top tissue also pulls the next part way out. <IMAGE>

Patent GB-2173096-A (GB)
Title: Improvements in or relating to baths
Inventor: BENTLEY MICHAEL STEVEN
IPC: A61H33/02
Filed: 1985-04-02
Abstract: A domestic bath 10 has an air supply pipe 12 through which air under pressure is supplied from a pump for agitating the water in the bath. The air from the pipe 12 is admitted to the bath through a plurality of openings 14. In one embodiment a small bore pipe 16 leads to a venturi 18 in the air supply pipe 12, and the reduction in air pressure in the venturi causes water to be sucked through the pipe 16 into the air stream to form a particulate suspension within the air stream. Thus, as the air bubbles are formed within the water in the bath, these bubbles themselves contain the moisture provided by the water flowing through the pipe 16. Other embodiments are described which also provide a water suspension in the air stream. <IMAGE>
