An inflatable bladder is defined by two superimposed outer sheets of heat-sealable synthetic plastic fused together about their peripheral edges. An Intermediate layer or baffle is disposed between the two outer sheets and is alternately sealed to one and the other of the outer sheets to form air cells on the opposite sides of the intermediate layer. Each of the air cells is defined by an opposed ...

A method of preparing ribbed ticks comprising a textile top sheet (60) and a textile bottom sheet (61) and partition-wall strips (1), said strips being welded along their opposite side edges to the top sheet and bottom sheet, respectively, by heating the entire surface of the joined webs of textile material after placing of lengths of folded partition-wall strips (1) in a given pattern, said strip...

A drive arrangement for a cutter blade, wherein operational cutting movement of the blade (11) is arranged to be derived from a servo-type motor (9) whose output is so controllable as to provide a drive output voltage/time relationship which produces a rapid initial acceleration from rest to a value which produces such angular velocity of the output shaft (10) of the motor as to establish a preter...

In a system for manufacturing and packaging cigarettes each production unit comprising a cigarette making machine and packaging machines has associated therewith a supply station to which bobbins of raw materials are supplied, that is tipping paper, cigarette paper, carton wrapping paper, inner frame material, box blanks, pack blanks, metallized paper and cellophane or polypropylene, this being do...

After a yarn interruption and a subsequent restoration of the yarn connection at the winding station of a textile machine, the yarn has to be transferred into its normal yarn running position on the yarn guide of the winding station. But the transfer of the yarn usually does not take place in synchronism with the movement of the yarn guide, and therefore the yarn may be deposited at one and the sa...

Salze organischer Carbonsäuren können von nicht salzartigen organischen Verbindungen mit Hilfe einer semipermeablen Membran aus einem Perfluorsulfonsäurepolymer oder Salzen dieser Polymeren getrennt werden, indem man eine Lösung der Salze und der organischen Verbindung in einem C1-C4-Alkanol mit einer Seite der Membran in Berührung bringt und sich auf der Gegenseite der Membran das reine Lösungsmi...

Biphenyl tetracarboxylic acid esters and derivatives thereof are prepared by the coupling reaction of 4-halogen substituted o-benzenedicarboxylic acid ester, carried out in an aprotic polar solvent in the presence of a pre-prepared triphenylphosphine-nickel chloride or trialkylphosphine-nickel chloride catalyst, zinc powder as the reducing agent, and an alkali metal halide promoting agent. The est...

An apparatus for applying a tire material such as carcass ply to a molding drum in a tire molding process wherein the cut leading end of the ply is caused to pressure-adhere onto the molding drum by a leading-end applying and pressure-adhering roller. The molding drum is caused to rotate at an angle less than one rotation, and thereafter the ply is cut by the cutter mechanism, and the molding drum...

An automatic transmission of a trans-axle type in which an input shaft is disposed above a differential across an axle of a vehicle. A case for the transmission is divided into a differential case for mounting a differential and a transmission case for an automatic transmission device. A bearing plate is disposed between the differential case and the transmission case. A drive pinion formed on an ...

A system for disengaging an electromagnetic clutch upon selection of an opposite driving range of an automatic transmission. When a forward driving range is selected during rearward driving or a rearward driving range is selected during forward driving, a loading shift signal is produced. In response to the loading shift signal at a vehicle speed higher than a clutch engaging vehicle speed, the el...

In a process and apparatus for spinning a package with a double yarn, which is used as a feed package for a subsequent twisting operation, it is provided that, when one or both fed slivers run out, an automatic splicing of new slivers is carried out.

The invention relates to a method of welding together plastic pipes which are unwound from a roll, and an apparatus for regeneration of the shape of plastic pipes before the welding operation. The invention consists in that first of all the shape of the plastic pipe is regenerated by closely enclosing the plastic pipe over part of its length in a cylindrical mould, then heating up the mould until ...

A machine for breaking up waste organic material such as the bark and branches of trees has a rotor (1) mounted inside a housing (3). The rotor has radial arms (4) which pass through a comb-like structure attached to the inside surface of the housing. The waste material is broken up by the radial arms (4) as they pass through the comb-like structure(2). The material is brought to the machine by an...

In an apparatus for the simultaneous winding of parallel tapes onto bobbins rotated by contact with an upper run of a conveyor mat carrying the tapes, each of the hubs for the bobbins is carried at the free end of a respective cantilever arm which is pivoted for movement in a vertical plane above the conveyor mat, the cantilever arms all being mounted on respective pivots on a frame structure posi...

Method for the knot-free connection of two threads formed of textile fibers of limited length having at least one twisted fiber strand, including a splicing device for mutually tangling, intermixing and intertwining individual fibers of the two threads, which includes inserting the two threads coming from opposite sides into the splicing device, trimming the end of each thread to a predetermined d...

A method and measuring instrument for determining photosynthesis quantum yield φp is provided.
