An appts. is added to an open-end rotary spinning unit to provide liq. to the newly spun yarn. The appts. is positioned between the output and the cross winding creel. The feed may be applied directly before or indirectly at the take-up roller pair. Pref. the open-end spinning rotor unit has sliver input with action of the opening roller to release separate fibres. Suction through the tube allows ...

Filter comprises a bell-type base module having an outer annular chamber with a feed line for the impure liquid and an inner chamber with a discharge line for the filtered product. A container is connectable at its upper end with the base module. A telescopic tube element is slidable within the base module and additionally serves to lock the fastening between the outer annular chamber and the cont...

An apparatus (11) for inspecting the sealing surface (86) of a container (15) for dips, saddles and lean is disclosed. While the container (15) is rotated, a beam (77) of light is projected horizontally above and through a finish portion of said container. An optical detector (100) detects the height of said sealing surface (86) by detecting the location of a minimum in the light beam. Dips in the...

The apparatus includes means for directing a plurality of beams of radiation of different spectral compositions to a sample such as a film or coating. A part of the beams is transmitted through the sample and received by a radiation detector. Another part of the beams reflected by the sample is in turn reflected, preferably by a concave mirror, back through the sample onto another radiation detect...

PURPOSE:To increase greatly that effective light amount of the whole emitted light amount from a light emitting layer which is taken out to outside the panel. CONSTITUTION:A light emitting layer 5 is divided in mesa form at every intersecting region of striped upper electrode 7a and lower electrode 3, and a reflecting member 7b is furnished at each mesa slope 20my of this divided light emitting la...

PURPOSE:To offer a plastic film liquid crystal display element which causes no appearance failure such as irregularity of color and the like even when external stress is given to the element. CONSTITUTION:A resin having <=0.05Nm<-2> elasticity (Young's modulus) is used for spacers 4 which support the gap between substrates 1. Therefore, when external stress is given, this elastic resin balls absor...

A method for the production of a cavity in a piston (23) is described. The method comprises the steps of forming a porous body around an element which has the shape of the desired cavity (17), heating to a temperature such that the element melts and infiltrates the porous body at least in the immediate vicinity of the resulting cavity. The article may then, for example, be incorporated into a pist...

A device adapted to be mounted on a ski comprising a first maintenance element, a pivotable plate adapted to pivot around an axis substantially perpendicular to the ski comprising a second maintenance element; and a braking assembly. The braking assembly comprises at least one braking element adapted to shift between active and inactive positions and at least one boot-sensitive element adapted to ...

For supplying power to the electronic circuits during the flight phase of a missile, a piezo-electric body in the missile, in conjunction with a seismic mass, is subjected to the mechanical vibrations of the missile and supplies to its electrodes an alternating voltage which, via a rectifier circuit, is used as the power supply during flight.

Symbols (y(n - L)) in a symbol sequence transmitted via a fading channel are estimated (S/< ANd >(n - L)) in an equalizer having a channel estimating filter (CEST). An error signal (e(n)) influences an adaptation circuit (10) which controls adjustable coefficients (7) so as to form a channel estimate (c1(n), c2(n), c3(n)), which is adapted during the whole of the symbol sequence. The adaptation ci...

A hydrocyclone (10) establishes a first vortex (15) of fluent material at one end (e.g. in a top portion 4), and a second vortex at the other end (e.g. in a bottom portion 24). The first vortex is established within a porous surface of revolution (18) to which gas or other fluid is supplied, passing through the porous surface into the first vortex. The second vortex is established by a conical end...

The present invention provides a container (10), especially a resealable liquid dispensing container, for dispensing sterile liquids, the container (10) comprising a reservoir and a dispensing neck (50), the neck (50) being hermetically sealed, a cap (20) being locatable over the neck (50) and comprising a piercing member (30), the piercing member (30) being so configured as to pierce the seal (90...

Crosslinked plasticized or unplasticized PVC products having gradient crosslinking density, with a high crosslinking density on the outer surface and a low or none crosslinking density at the bulk of the product, are prepared by immersing the PVC product in a hot water solution of a crosslinking material and a phase transfer catalyst.
