Abstract: The activity of angiotensin converting enzyme (ACE) is measured in biological samples as body fluids. ACE-activity is estimated in minimally diluted specimens, using the natural substrate angiotensin I at close to physiological concentration. Femtomoles of generated angiotensin II are trapped by specific high affinity monoclonal antibodies and thus protected from degradation by angiotensinases during the incubation step. The same antibodies are subsequently used for quantitation by radioimmunoassay.

Abstract: The system possesses a guide body (1) with a continuous bore having an outlet orifice (3). A needle body contains a continuous yarn channel which is oriented coaxially with the bore of the guide body (1). One end of the needle body extends into a conical entry portion of the guide-body bore and forms with this a passage gap for the blowing air. The blowing air is introduced through two feed bores (11, 12) into the annular space in front of the passage gap. A baffle body (9) is arranged in the region of the outlet orifice (3). A yarn (FT) issuing from the outlet orifice (3) is deflected in front of the baffle body (9) out of a mid-plane (M) which contains the axis of the guide-body bore and the surface centre of gravity (A) of the mouth cross-sections of the feed bores (11, 12). The textured yarn thereby becomes more compact and has only small, regularly distributed projecting loops.

Abstract: In the optical fiber, the concentration of fluorine doped in the core portion (2) is made nonuniform in the radial direction to be greater at the center portion of the core portion (2) and less at the outer circumferential portion of the core portion (2). As a result, the distribution of the refractive index of the core portion (2) and the cladding portion (4) before the process of transparent glassification becomes a profile which is high at the outer circumferential portion of the core portion (2) and which is low at the center portion. The reduction of the refractive index at the outer circumferential portion of the core portion (2) due to the dispersion of the GeO₂ etc., the oxide included in the core portion (2), in the cladding portion (4) in the transparent glassification processed is and as a result, the profile of the refractive index of the core portion (2) becomes one which sticks out in a step form with respect to the cladding portion (4).

Abstract: An armrest attachable to a tool to provide support for a worker's wrist while the tool is being manipulated or actuated. The armrest underlies the worker's forearm so the weight of the tool is borne partly by the worker's fingers and hand and partly by the worker's forearm. Stress on the wrist is minimized and good wrist posture is maintained. Due to the location of the armrest, the worker's forearm is located directly behind the tool handle where it can absorb kickback forces that occur as an incidental part of a lockbolt installation process.

Abstract: The invention relates to a method of forming a plasma (32) for assisting in the production of a ceramic material such as diamond (33). The method includes the steps of providing a bell jar (28), and introducing a selected gas into the bell jar. The gas may comprise an active gas such as hydrogen, and a gaseous carbon compound. A beam of microwave radiation (16) is generated from a remote source (10), and is focused using an array of lenses or mirrors (18, 22) to a focal region (26) within the reaction chamber so as to form a plasma (32) in this region. The shape of the plasma is independent of the inner profile of the chamber and dependent on the geometry and position of the focusing array. A substrate (30) is located within the reaction chamber, and the plasma interacts with the substrate so as to cause chemical vapour deposition of, for instance, a plasma activated carbon component of the plasma onto the substrate. The invention extends to apparatus for use in the method.

Abstract: L'ensemble (10) utilise l'imagerie en temps réel pour détecter le rayonnement en provenance du champ d'un objet (12) dont une composante est périodique dans le temps. Une caméra vidéo (14) détecte le rayonnement émis et réfléchi en provenance du champ de l'objet (12) et produit un signal vidéo comprenant une série de pixels représentant une image complète de l'objet. Une valeur moyenne de décalage obtenue dynamiquement et dérivée du signal vidéo original est soustraite du signal vidéo, laissant seulement les informations relatives à la composante variant dans le temps du champ de l'objet vidéo. Le signal résultant de cette soustraction est numérisé par un numériseur (18) contenu dans un processeur (16). Le processeur (16) établit la valeur moyenne des images complètes successives en tant qu'images synchrones, sur la base de la périodicité du champ de l'objet (12) pour éliminer le bruit asynchrone de l'image et pour afficher une image synchrone en fonction de la périodicité du champ de l'objet (12). Etant donné que l'image vidéo finale est le résultat de la numérisation de la différence amplifiée, la plage dynamique de l'image corrigée est très augmentée.
