    Abstract: An alloy of composition (by mole) around Fe80B15Si5 with additions of up to 4 mole % Ag or Cu or up to 2% Zn or mixtures thereof when rapidly cooled solidifies to a non-crystalline glass structure, which is ductile and magnetically "soft", i.e. offering a reasonable saturation magnetisation yet with low losses. Exemplary glassy alloy: Fe79.5B15Si5Cu0.5.

    Abstract: Procede d'identification de beta-lactamases en controlant specifiquement les reactions de concurrence entre un substrat chromogene, par exemple la nitrocefine, et divers substrats en concurrence, de preference certains des beta-lactames les plus recents, par exemple la cefoxitine, le moxalactame, MK 0787 etc. Une etude detaillee de ces reactions par l'inventeur a revele des variations accentuees auxquelles on ne s'attendait pas dans la reactivite (affinite) de ces enzymes pour les differents beta-lactames. Sur cette base l'invention fournit un test d'analyse pour l'identification des beta-lactamases'inconnues'basee sur la comparaison de leur comportement dans la reaction de concurrence avec des donnees d'affinite sur des beta-lactamases connues. Le substrat chromogene et une selection des beta-lactames les plus utiles sont fournis sous forme de 'kit'. Il peut contenir des melanges prepares des beta-lactames et du substrat chromogene. Le test d'analyse peut s'effectuer visuellement en utilisant des plaques de micro-titrage et un simple systeme de comptage ou plus quantitativement par analyse spectro-photometrique. Il peut etre utilise pour l'identification rapide des beta-lactamases dans un laboratoire d'hopital ou pour l'identification des bacteries gram-negatives basees sur les beta-lactamases qu'elles produisent.

    Abstract: A syringe is provided comprising a barrel (10) open at one end, a piston (20) sealably located in the barrel and being partly formed by a membrane (23), a plunger (30) slidable into the barrel to engage and move the piston, and a needle (40) projecting through the plunger into and out of the barrel. A material to be dispensed is located between the barrel and piston, and plunger movement causes the needle to pierce the membrane and also causes the piston to move to eject material through the needle. Preferably a protective cap (50) is connected with the barrel to cover the plunger/needle projection. Typically the dispensed material is pharmaceutical and it can be maintained sterile by suitable sealing of the piston and/or cap with the barrel. The plunger can interlock with the piston to allow withdrawal movement useful in intravenous injection. Also the barrel closed end can include another membrane (62) allowing mixture of another material, such as a solvent or diluent liquid.

    Abstract: In apparatus for sensing and controlling the deposition of a thin film on to a substrate (12) from a gas or vapour phase, the optical reflectance or transmittance is sensed, the resonant frequency of a crystal (14) also exposed to the deposition is sensed, and the quotient of the change in each signal over a predetermined time interval is determined. The deposition can be terminated at a suitable thickness, for example a reflectance or transmittance maximum or minimum. Instead of an optical property, the electrical resistivity of the film may be sensed and used in the same way.

    Abstract: A surface on which there is a regular periodic pattern, often a relief pattern (12), is deformed, and in-plane deformation is sensed by illuminating the deformed pattern with a beam (12) of coherent light so that light is reflected as one zero order beam and a plurality of diffracted beams, and combining two of the beams (16, 18) so that they interfere in a manner related to the deformation along the direction of intersection of the surface plane with the plane in which the two interfering beams lie. The magnitude and direction of in-plane deformation in one or more directions and the magnitude and direction of the maximum in-plane stress or strain, can be determined automatically.

    Abstract: A crop cutting apparatus has two vertical axis rotary drum cutters (13), each having an upper rotor with a crop conveying surface (19) and a lower rotor carrying knives (21). Gears drive the upper and lower rotors at different angular velocities. The lower rotor has an annular rim (18) having an upper surface shaped to continue the outline of the conveying surface (19). The knives (21) protrude outwardly from beneath the rim (18) and rotate with the rim. A wiper brush (34) mounted on the conveying surface (19) projects outwardly over the rim (18) for lifting and transferring crop to the surface (19). The upper rotor may have conditioning brushes (35) for conveying crop and conditioning crop by relative movement between the brushes and the crop. The upper and lower rotors may be rotated in opposite senses to effect at least partial shear cutting.
