Abstract: A device for monitoring torsional vibrations in a rotary shaft (10) comprises a laser source (14), a 50% transmission-reflection beamsplitter (18) and a mirror (20) arranged to provide two spaced parallel laser beams (16 and 17) which strike the surface of the shaft (10) at points (A) and (B) respectively. Since the shaft surface is moving, light backscattered at the surface is Doppler shifted and since the velocity of the surface at points (A) and (B) differs, the frequency of light backscattered at the two points is shifted by different amounts. Light backscattered along the axes of the incident beams (16 and 17) is mixed and directed into a detector (22) where it heterodynes. The frequency at which the detected light intensity is modulated is directly proportional to the speed of rotation of the shaft (10). 
     The device, and the method it embodies, can be used to measure the difference in velocity at two points on any surface undergoing non-uniform motion and can, therefore, be used generally to characterise vibrational motion.

Abstract: A hot isostatic pressing apparatus comprising a pressure vessel (5), heater (9) and heat-insulating layer (10, 201 interposed between the wall of the pressure vessel (5) and the heater (9). The heat-insulating layer (10, 20) is formed of a least two layers, ie an inner layer (10) and an outer layer (20). The inner layer (10) surrounds an object (M), which is under treatment, and the heater (9). The inner layer (10) is loadable into and unloadable from the pressure vessel (5) together with the object (M) and heater (9) while maintaining a chamber, which is surrounded by the inner layer (10), hermetically isolated from the surrounding atmosphere. However, the outer layer (20) remains within the pressure vessel (5). When the hot isostatic pressing apparatus is incorporated in a modular HIP system, the cooling time is considerable shortened and the efficiency of the HIP treatment is hence improved to a considerable extent.

Abstract: Dans un système de surveillance anti-vol à l'étalage, un premier et un second récepteurs sont utilisés de chaque côté d'une porte surveillée ("COTE UN" "COTE DEUX" de la Fig. 1). Ces récepteurs détectent les perturbations d'un champ électromagnétique produites par la présence d'un marqueur à haute perméabilité et à faible coercivité. Les sorties (A, B ou A', B' de la Fig. 1) de ces récepteurs produisent un signal d'addition et un signal différentiel dans un pré-amplificateur (1). Les harmoniques supérieures du signal d'addition sont accentuées dans un amplificateur/filtre (2) et les harmoniques inférieures du signal différentiel sont accentuées dans un amplificateur-inhibiteur (3). Le rapport entre les harmoniques supérieures et les harmoniques inférieures est déterminé par un circuit logique de traitement (9) afin de contrôler la présence d'un marqueur. Pour augmenter la sensibilité à des orientations diverses d'un marqueur, un régulateur de phase (5) et une commande de phase (6) renversent périodiquement la phase d'un des récepteurs. Pour améliorer la réjection des bruits, un générateurde minutage (4) inhibe la réception pendant que les bobines de transmission du système sont activées, et limite en outre le traitement des signaux reçus au premier quart de chaque cycle (moment où les perturbations causées par un marqueur sont les plus probables).

Abstract: A thyristor semiconductor switching device is self-protected against forward voltage breakover by a localized avalanche voltage breakover zone which ensures that forward voltage breakover will occur in a known region of the device where a non-destructive, controlled turn-on process can be initiated. The localized avalanche voltage breakover zone in one form includes a recess extending into the P-base region of the device to locally increase the avalanche multiplication factor. In one embodiment, the recess extends only partly through the P-base layer. In another embodiment, the recess extends completely through the P-base layer. In another form, the avalanche voltage breakoverzone is planar and comprises a portion of the N-base layer extending through the P-base layer such that a portion of the PN junction between the P-base and the N-base has a radius of curvature and such that a gap is defined between opposed portions of the P-base layer. In the case of the recess the surface-adjacent region of the recess comprises a field-containing layer of conductivity type, but doped higher in concentration than the P-base region. Thus the field-containing layer comprises an electrical extension of the P-base region. The thyristor has a blocking PN junction having a depletion region extending into the field-containing layer. The thickness of the field-containing region is greater than the depletion layer width in the field-containing layer under device forward blocking conditions. In the case of the curved PN junction, the surface-adjacent region of the N-base extending portion comprises a field-containing layer of P conductivity type doped higher in concentration than the P-base region and comprising an electrical extension thereof. As a result, in either case no electric field lines terminate at the surface ofthe field-containing layer. No surface passivating film is required.

Abstract: A cellulosic hollow fiber which is being particularly adapted for use in hemodialysis or a similar extracorporeal treatment of blood, is possibly after rinsing with an alcoholic solution or fluorinated hydrocarbons- exposed to swelling with use of an aqueous solution prior to drying and/steriliza- tion of the hollow fiber. 
     Examples of aqueous solutions can be water, water/ glycerol, and water/glycerol/alcohol. Preferably said aqueous solution contains glycerol in an amount of4-35%, such as 12-35%, preferably 16-35%. 
     The aqueous solution can be applied to the inside and/or the outside of the hollow fiber so as to bring about a diffusive and/or a convective transport of water and/or glycerol into the hollow fiber wall. The rate of diffusion can be increased by increasing the temperature of the aqueous solution, by increasing the contact time between the aqueous solution and the hollow fiber, or by increasing the glycerol content of the aqueous solution, and the convective transport of said substances is achieved by applying the aqueous solution under pressure. 
     After drying, the hollow fiber can be sterilized either by temperature or by radiation without any substantial loss of permeability characteristics.
