A shaft is rotatably and displaceably mounted within the bushing. A cla...

An absorbent pad (11,13,15) for wearing during weak menstruation has a triangular cross-section to enable it to be fitted between the smaller lips of the vulva. The pad may have rounded ends and rounded apex. - The pad is made of several layers of flexible material so that it easily conforms to the shape of the anatomy. The pad is intended for use outside the time of normal menstruation and is con...

Supertwist liquid-crystal displays having excellent properties are obtained if the nematic liquid-crystal mixture is based on the component A, which contains - one or more compounds of the formulae IIa or IIb - one or more compounds of the formulae IIc to IIe - and one or more compounds of the formulae IIf to IIk in which R, L<1> and L<2> and X are as defined in C...

A process for making foamed metal bodies is described, in which a mixture (17) of a metal powder (15) and a gas-evolving blowing agent powder (16) is thermocompacted to form a semi-finished product (19), at a temperature at which the bond of the metal powder particles predominantly takes place by diffusion and at a pressure which is high enough to prevent the decomposition of the blowing agent, in...

A reusable textile urine storage pad has an anatomically conforming shape, pref. additionally inlaid during wrapping and positionable corresponding to the urine outlet point. The pad may have additional internal textile absorbent inlays. ADVANTAGE - The pad can be washed separately from a nappy which can be reused without washing thus reducing washing costs and pollution.

A coated reinforcement material comprises a reinforcement having a coating of the general formula: AxSi100-x wherein A is selected from the group consisting of Au, Pt, Ru, Rh, Ni, Pd, Ir and combinations thereof; and x is within the range of greater than zero to about 40. The reinforcement is preferably selected from Si3N4, SiAlON, Si, AlON, B4C and SiC. The invention further relates to a hig...

Improvements are made in a panty protector (10) of the kind comprising adhesive attachment (16) and provided with transversely extending flaps (24). The peripheral shape of the protector is such that it is possible to produce the sheet of material of construction for the protector (10) and simply cut said shapes out of said sheets with minimal waste.

Extrusion techniques for producing populations of liposomes having a substantially unimodal size distribution and for producing unilamellar liposomes. The unimodal size distribution is achieved by repeatedly passing previously formed liposomes through one or a plurality of filters, all of which have the same pore size. The unilamellar liposomes are produced by using a filter which has a pore size ...

LAS PERSIANAS HASTA AHORA CONOCIDAD PARA CERRAR APERTURAS SE COMPONEN DE LISTONES DE PERSIANA INDIVIDUALES OPACOS (2) POR LO QUE NO SON APROPIADAS PARA ESCAPARATES Y DAN LA SENSACION EN UN ESPACIO HABITABLE CUANDO, ESTAN ECHADAS, DE UNA CARCEL. PARA FACILITAR UNA VISUALIZACION CUANDO LAS PERSIANAS ESTAN ECHADAS, TANTO DE FUERA HACIA DENTRO COMO AL CONTRARIO SE PROPONE UN ESTAR DE PERSIANA DE LISTO...

The invention relates to a motor with a reduction gear unit and a gearbox output shaft which has an inner profile, for coupling to the externally profiled shaft of a shutter or some other device. The planet carrier of the motor is provided with a basic inner profile and an insert is inserted into the basic profile of the planet carrier before coupling to the shaft, to be driven, of a device in ord...

Proposed is a device designed to simulate the electrical behaviour of a spark plug. The device includes a series-connected circuit comprising at least one resistor (8) and two four-layer diodes (6, 7) connected in antiparallel arrangement. When a given high voltage is reached, breakover of the four-layer diodes (6, 7) occurs in the same way as in a spark plug, the voltage drop across the resistanc...

In a microwave circuit, constructed using triplate technology, the core of the stripline is formed from a carrier plate of dielectric material which is coated on at least two sides with a metallic layer and is held between the printed-circuit boards in a self-supporting manner by means of stays via narrow webs of dielectric material, which project laterally and are likewise formed from the carrier...

A switching-off device is represented and described for the geared motor of limit position-controlled devices such as sliding gates, roller shutters, furnace doors, sound-absorbing hoods, lowering windows etc. by means of fixed switches and at least one switch actuating element such as a switch cam or the like, moved by the motor drive by way of a switch actuating mechanism, the switches and the s...

An impulse ink jet apparatus capable of printing bar codes comprises a plurality of side-by-side chambers extending along a line slanted with respect to the direction of scanning. Each of the chambers includes a plurality of orifices arranged along a line extending substantially transverse to the scanning direction and means for ejecting a plurality of droplets from the orifices of each chamber.

The droplet ejector has a pool of liquid with a free surface and a source producing a pressure wave in the pool. A capillary wave emission controller for the injector includes a conductor and a counter electrode. The conductor is adjacent the surface of the liquid, near the focus of the pressure wave. A source is coupled across the condutor and the counter electrode to apply a periodic voltage ac...

A technique for handling filamentary material, especially optical fibre packages, in which the filamentary material (2) is coiled into an annular pan (1) in a series of turns each of which is offset from preceding turns. The turns each contain 360 degrees of torsion which is relieved when the filamentary material is paid out from the pan. A rosetting head for laying the pattern sequence is located...
