A fault monitoring circuit is arranged to continuously monitor signals IP(0) to IP(N) from a number of different signal sources. A modulo-2 adder (3) combines the signals from the sources to produce a signal which is used by a linear feedback shift register to produce a signature indicative of those sequences within the signals from successive time intervals, so as to provide an indication of any ...

Date Dec. 23, 1992.A heel unit (10) of a safety ski binding comprises a unidirectional blocking arrangement (60') with at least one blocking member (62') arranged between a sole holder (16) and a spring biased return cam (26). The unidirectional blocking arrang...

The invention relates to a front ski-binding element which is intended to hold the end of a boot bearing on a ski. The element comprises a base (3), and a body (8) which is movable with respect to the base (3) parallel to a median longitudinal and vertical plane of the ski. Moreover, the body carries a member (15) for holding the front end of the boot. The body (8) and the base (3) are connected t...

Bead portions of a tire are supported during tire manufacture by a bead support assembly (100, 1100, 2100) having relatively movable parts that cooperate to define an elongate, outwardly opening groove (200, 1200, 2200) that receives and supports the bead portions (B). The relatively movable parts include a flexible cover (170, 1170, 2170) that overlies a relatively rigid underlying support (120, ...

La presente invención se refiere a una película de polímero de etileno encogible con calor, caracterizada porque tiene un encogimiento térmico de área de cuando menos 20 por ciento a 90 grados C y una variación de espesor de no más de 20 por ciento, siendo la película de etileno encogible con calo una película biaxialmente estirada de un polímero de etileno que comrende por lo menos un copolímer...

The invention comprises polymer compositions containing cross-linked biodegradable derivatives of chitin for use in preventing adhesion between body tissues.

An absorbent cellular polymeric material is provided which exhibits enhanced water retentivity and may also exhibit enhanced compressibility. Such a material is provided by foaming the reaction product of a poly(aminoether) and an epoxy resin and quaternizing the resulting reaction product with, for example, an acid. The foam is particularly usable in products for absorbing body fluids.

A highly absorbent polymer comprises water-insoluble, hydrophilic, crosslinked polymer particles having carboxyl or carboxylate groups, characterised in that said water-insoluble, hydrophilic, crosslinked polymer particles have an absorbing capacity satisfying the following requirements (i) to (iii), said absorbing capacity being imparted by enhancing the crosslinking density of the surfaces of sa...

The present invention relates to a method for determining at least one dynamic flow characteristic of a multiphase flow circulating in a pipe, said flow being composed of at least a lighter dispersed-phase and a heavier continuous-phase. A tracer is discharged (or activated) into the flow at a chosen first location in the pipe by mixing (or activating) at least a portion of the tracer with the con...

A differential gear unit includes a viscous coupling for restricting the differential rotation of output gears (27, 29), with the conneciton of one of the parts (31) of the viscous coupling to one output gear being by way of a releasable connecting device so that the viscous coupling can be brought out of operation when required, e.g. under vehicle braking.
