The yarn to be transferred is fed at high speed through a traverse mechanism and between a drive roll and a bobbin mounted on a first chuck and rotated by the drive roll to cross-wind a yarn package. An empty bobbin is mounted on a second chuck parallel to the first chuck. When the package is substantially full wound, the empty bobbin is engaged with the drive roll and the yarn package is retracte...

This invention relates to a liquid composition comprising a C3-C8 carboxylic acid, an ion selected from NH4+ and a Group I or Group II metal according to the Periodic Table due to Mendeleef, and water, the ratio of acid to cation is between 2.1 and 4:1 on a chemical equivalent basis.

The invention relates to a blood centrifugation cell, comprising an outer rotatable container (1) delimiting a portion of space in which a body is provided which is rigidly connected therewith and is formed by two revolution walls (2,3) connected at the ends, a stationary joint (10) being provided at the top of the container (1) and comprising two conduits (11,12) which are coaxial to the joint, t...

The invention relates to a continuous blood centrifugation cell, comprising an outer rotating container (1) which accomodates a body, rigidly connected therewith and coaxial thereto and formed by two walls (2,3) joined at the ends, the outer container (1) carrying at its top portion a stationary joint (9) comprising conduits (10,11,12) which are coaxial to the stationary joint (9), the outer condu...

One end of a drawstring which is connected to a catamenial tampon at the other end is pulled downwardly by suction while an intermediate portion of the drawstring is convoluted around a hollow mandrel to form a closed loop. The one end of the drawstring is then drawn into the mandrel by suction to convert the loop into a relatively loose knot which is or can be tightened by exerting a pull by suct...

A valve member is latched into open or closed positions by permanent magnetic poles against the force of compressed springs. A coil associated with each position, when activated with a current, cancels the magnetic field of the permanent magnetic pole holding the valve member and allows the compressed spring to move the member quickly through a central neutral position toward the other position, w...

In an electromagnetic switch for a starter motor, power produced by friction from repeated opening and closing of the stationary and movable contacts 22, 26 is prevented from entering between the sliding parts of the movable iron core assembly 4, thus ensuring smooth sliding motion of the movable iron core assembly at all times, and the penetration of external water into the spaced defined by the ...

A parallelogram bracket assembly with a force balance mechanism which utilizes a pneumatic spring situated in the parallelogram bracket assembly. The pneumatic spring has a cylinder receiving a piston which has a piston rod and the cylinder is supported against parts connected to one articulated axle and an end of the piston rod is supported against parts which are connected to an articulated axle...

Wundabdeckungen werden bekanntlich für Brandwunden, großflächige Hautwunden, Hautdefekte oder dergleichen benötigt. Derartige Wunden sind einer Kontamination durch Keime, und zwar einschließlich Pilze, ausgesetzt und können dann zu septischen Wunden werden, die schlecht heilen und eine spezielle Wundabdeckung und Wundbehandlung erfordern. Es soll eine Wundabdeckung geschaffen werden, die für Sauer...

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur automatischen exakten Anbringung der Wulstkernringe an eine Reifenkarkasse. Indem man die Wulstkernringe auf sogenannte Tragringe auflegt und dann gleichzeitig diese Tragringe konzentrisch aufweitet und die Wulstkernringe axial auf ihnen verschiebt und senkrecht zur Wickeltrommelachse ausrichtet, erreicht man ihre reproduzierbar genaue,...

Coatings, which act as barrier layers to inhibit migration of alkali metal ions from a glass surface and/or act as colour suppressing underlayers for overlying infra-red reflecting or electrically conducting layers, are deposited by pyrolysis of a gaseous mixture of a silane, an unsaturated hydrocarbon and carbon dioxide on a hot glass surface at a temperature of 600 DEG C to 750 DEG C.

The utility model discloses a box type inner chamber for a solar energy water heater. The upper end and the lower end of the box of the box type inner chamber are semicircular. A pulling strength pipe is welded between the inner walls of the box. A strengthening frame is arranged outside the box. The inner walls of the box are coated with anticorrosive layers. The utility model can be used as the ...

A method of producing a tension-proof thread connection by splicing includes preparing threads for splicing by contacting ends of the thread with a hot gas before splicing for dissolving the thread ends into open-ended individual fibers, for softening the individual fibers and for making the fibers better suited for splicing; and subsequently splicing the threads by alternatingly tangling, interlo...
