A bipolar electrocautery surgical snare is described capable of performing the endoscopic removal of growths within a body cavity with improved precision and accuracy. The bipolar surgical snare comprises an electrically insulating elongated double lumen tubular member, a pair of flexible electrically conductive snare wires extending through the respective lumina of the tubular member and from eac...

Flexible layered product for use in waterproof garments or tents of a textile material covered with a waterproof material having a water vapor transmission rate of at least 1000 g/m2 day, the textile material being covered with a film of a copolyether ester consisting of a plurality of recurrent intralinear long-chain ester units and short-chain ester units which are randomly joined head-to-tail t...

A resilient polyurethane foam with improved resistance to ignition which passes the flame test of BS 5852: Part 1 for material-covered fillings as used for upholstered furniture when adapted for testing the foam only, which foam has on at least one surface thereof at least one coating of a vinylidene chloride polymer of a composition thereof which polymer or composition is substantially absent fro...

The glass (9) is surmounted by a grid, the ends (10a) of the rods (10) which constitute it forming feet passing through the bezel (8), an outer calibre (4) and the back (7) of the case. These ends (10a), which are threaded, serve as ties for assembling the elements of the case, axial tightening being ensured by nuts (15) screwed onto these ends (10a).

The back (3) has two projections (3a) extending over a width slightly less than that of the small sides of the case and which each terminate in a rim (3b). These projections (3a-3b) are engaged in blind hollows (6) in the strap (4) in which they are held fast. The strap (4) is prevented from inadvertently coming free of the two projections (3a-3b) by a ring (7) driven onto the case body (1). The f...

It includes a drive module (M) provided with a first power take-off consisting of a toothed wheel (2) solid with the cannon-pinion (15) and with a second power take-off consisting of a pinion (1) fixed to the axle of the centre-seconds (14). It also includes a chronograph module (C), the chronograph wheelwork of which is driven by the second power take-off (1) whilst the time-display wheelwork is ...

A process is provided for mechanically surface-finishing a textile fabric which comprises ccontinuously feeding said fabric from a source of supply, such that said fabric lies in a single plane, subjecting successive adjacent sections of the fabric to intermittent mechanical impact with an abrasive means across the width of said fabric thereby avoiding substantial sustained contact between the fab...

A light box is for supporting a stack of essentially transparent sheets including photo material which is insensitive to daylight and sensitive to shortwave light, and a record carrier film having transparent regions in the form of the characters or other representations to be produced and an opaque background to shortwave light. The illumination by the light box facilitates positioning of the rec...

A method and means are provided to facilitate the composition of the layout of material such as the comic and puzzle pages of a newspaper. This is accomplished by employing translucent plastic modules cut to established size standards upon which the artwork to be supported is pasted. These modules with attached artwork are then assembled as desired upon a translucent plastic copy board, locked in ...

A method and system for injecting coal and process fluids into a fluidized bed gasification reactor. Three concentric tubes extend vertically upward into the fluidized bed. Coal particulates in a transport gas are injected through an inner tube, and an oxygen rich mixture of oxygen and steam are injected through an inner annulus about the inner tube. A gaseous medium relatively lean in oxygen cont...
