Abstract: A shield device for use in sheathing a hypodermic needle (11) includes a pair of flap members (26, 27) which are hinged to a central elongate narrow plate (25) within which an open mouth (15) of the sheath is defined. The flap members (26, 27) are hinged on either side of the central plate (25) so that they can move from a retracted position lying parallel and on respective sides of the central sheath (13) to a deployed position in which they form with the central plate (25) a protective shield to hide fingers of the user from pricking as the needle (11) is inserted into sheath (13). The flap members (26, 27) are retained in the retracted position by a simple latching arrangement (40, 41, 43) which is released by compression of the flap members (26, 27). The sheath (13) and shield can be packaged as a disposable item in conventional manner with the disposable needle (11) and needle base (10) and can be used without modifying traditional handling techniques.

Abstract: In dashboards formed by a multilayer film arrangement which is foam-backed by PUR foam, there is a risk of the films tearing on significant exposure to heat since the PUR foam layer decomposes at elevated temperatures and the resultant decomposition products enter the film, where they catalyse decomposition of the film. 
<??>In order to avoid this disadvantage, the film arrangement is designed, in a novel manner, so that at least one film layer contains light-reflecting material or powders or pigments, which reduce warming of the film due to radiant heat.

Abstract: The invention relates to a device for generating a plasma with the aid of circular-polarised microwaves. In this case, the linear-polarised microwave emerging from a microwave oscillator is converted in a commercially available mode converter and a standard round waveguide into a circular-polarised wave and is then passed via a horn to the cross-section of a plasma chamber. In consequence, there is no need for special matching of the mode converter to the source geometry. In addition, the plasma volume and hence the substrate area can be selected to be very large.

Abstract: A technique for permanently joining thermoplastic parts (10,20) in a single stroke converts kinetic energy into thermal energy. In this technique, one of the thermoplastic parts (10) includes a linear shaft (12) while the other includes a cavity (22) having the same general shape but being slightly smaller in its cross­section. The thermoplastic parts are permanently joined when the shaft is thrust into the cavity at a velocity that exceeds a predetermined minimum value which is a function of the thermoplastic materials used and the relative dimensions of the shaft and cavity. An interference fit between the shaft and cavity causes frictional heat to be generated which melts the contacting surfaces and thus welds the parts together after a brief cooling period.
