The yarn pieces to be joined are stretched between the two pairs of suction tubes (28, 29; 30, 31) and untwisted by being wound about spindles (20, 21). Hot compressed air fed along the surface of two blocks (32, 33) adjacent to the untwisted yarn portions remove free fibers and distribute the fiber tufts in the base of a channel formed in said blocks (32, 33). Said tufts are retained in the base ...

1. A process for the elimination or avoidance of troublesome edge displacement on the impacting faces of tube ends (1) that are to be joined together by means of a welded seam, in which each of the tube ends (1) is pushed on to a sizing plug (5) combined with a press die (3) and thereby the face of the tube end (1) is provided with a profile for the welding seam by compression against an end face ...

In order to obtain a good durable and strong yarn connection by splicing, the individual fibres of the yarn ends are made parallel and initially held next to and at a distance from one another in free space, in such a way that the fibres of the yarn ends overlap at a distance from one another, whereupon fibre tufts (147', 148') are formed by applying a homopolar electrical charge to the two yarn e...

The invention provides an apparatus for removing an animal from a shell. The apparatus has a tubular helical main portion having an inlet, an outlet and an attachment portion for coupling the apparatus to a source of high pressure fluid. The apparatus may be inserted into the shell and coupled to high pressure fluid which urges the animal from the shell.

Compositions for application to the interior surface of the tread of a pneumatic tire to facilitate relative movement between contacting portions of the interior surface when the tire is driven deflated, comprise a polybutene, an acrylic polymer or a polyolefin as a gelling agent for the polybutene, and a particulate solid puncture sealing material. Preferred gelling agents are polyethylenes, espe...

PURPOSE:To check on memory contents securely through simple constitution, by checking memories according check programs from other memories. CONSTITUTION:In ROMs 2, 3-, the control program of a microprocessor 1 is stored. According to the state of an FF14 after the power source is turned on, a check program 11 is read out of the ROM2 through a processor 1 and through the processing of the processo...

PURPOSE:To prevent the breakage of an offshore structure by lessening the force of icing by providing legs and ice breakers in a nearly circular form to a jacket type offshore structure. CONSTITUTION:Legs 3 for the outermost side are provided to the lower part of a platform 4 in such a way as to arrange them on a circle A. By this, even when jamming phenomenon occurs, the total force of icing is r...
