Abstract: Appareil et procédé dans le domaine de la thérapie des rayons X utilisés pour traiter par rayonnement une partie intercrânienne d'un patient. L'appareil et le procédé sont utilisés pour résoudre les problèmes d'imprécision géométrique dus à un fléchissement ou à des taux de dosage inappropriés lorsqu'un petit collimateur est utilisé. Ces problèmes sont résolus grâce au présent dispositif qui comprend un accélérateur linéaire pour envoyer des électrons énergétiques à un collimateur (14) qui envoie des rayons X à une région (F1). Le collimateur (14) comprend une pluralité de canaux (26) orientés vers la région (F1). Chaque canal (26) possède une cible (32) qui produit un rayonnement de rayons X lorsque la cible respective (26) est exposée sélectivement aux électrons. Le collimateur (14) possède une couche de couverture d'un matériau d'atténuation (54) du rayonnement qui s'étend sur la surface externe du collimateur (14), laissant les canaux (26) exposés aux électrons. De préférence, la couche de couverture (54) possède une épaisseur au moins égale à la portée des électrons énergétiques.

Abstract: L'appareil décrit sert à détecter la présence et/ou à mesurer la concentration d'un analyte (24) dans un milieu fluide (22). Ledit appareil se fonde sur la liaison biospécifique entre un système de liaison biochimique (20) et l'analyte (24), afin de faire varier les propriétés diélectriques d'un détecteur d'affinité capacitive. On optimise le détecteur d'affinité biologique en réglant l'épaisseur et les propriétés diélectriques d'une couche de passivation (16) pour les adapter généralement à l'impédance du système de liaison biologique (20, 21) et en réduisant au miniumum la capacitance de la couche double, de façon à maximiser les modifications de capacitance en volume associées au système de liaison biologique (20, 21).

Abstract: The invention relates to a process for the preparation of a storage material having photostimulated luminescence, in which a compound of barium with fluorine and bromine which contains a dope is sintered. According to the invention, barium fluoride BaF2 and barium bromide BaBr2 and cerium halide as dope are used to prepare a powder mixture, which is warmed to a temperature of from about 500 to 1150 DEG C. Excess barium bromide BaBr2 is subsequently washed out by a washing process, and conditioning at from about 200 to 1000 DEG C in a reducing gas is then effected. Using this storage material, the X-ray information can be stored in a stable manner, and a short read-out time is obtained. For example, an X-ray image containing about 4,000,000 pixels can be read out in about one second.

Abstract: A composite membrane comprises an inorganic support having interstices and porous inorganic films of sintered non-metallic particles carried by the support and bridging the interstices thereof. The support is preferably a woven metal mesh, with the films substantially coplanar with the support. The films may be formed by applying a suspenion of refractory particles in a polymer solution to bridge the interstices of the support, and heating the films to partly sinter the particles. Since the films are in compression at ambient temperature, any cracks that may be formed by damage to the composite membrane tend not to propagate.

Abstract: Apparatus for synchronising a clock signal to a pulse comprises a clock signal generator (1) for generating a first clock signal having a frequency equal to that of a desired clock signal. A delay circuit (2) to which the first clock signal is fed generates a number of time delayed versions of the first clock signal, each time delay being less than the period of the first clock signals. Logic (9) compares the time delayed versions of the first clock signal and the original clock signal at the time of occurrence of the pulse and selects as the desired clock signal, a version of the first clock signal which has changed state close to the time of occurrence of the pulse.

Abstract: In order to convert an interrupted clock into an uninterrupted clock, an integrated circuit is required in which no faults occur due to spikes. Said circuit consists of a phase control circuit in which the frequency (FE) of a read-in clock is fed via a frequency divider (2) to a phase discriminator (3) and the frequency (FA) of a read-out clock is fed to said phase discriminator via another frequency divider (15). A sequence of clocks (FHI - FHn) which are phase-shifted with respect to one another are derived in a generator (8) from an auxiliary frequency (FH) of a quartz oscillator (12) by means of a device (16). Which of these clocks gives rise to the read-out clock (FA) after division in the frequency divider (13) is determined by a switching frequency nFX which a frequency divider (7) controlled by the phase discriminator (3) transmits to the generator (8). This arrangement can be used in digital signal multiplexers.
