Abstract: The problems of shadows cast by the bars of the anti-diffusing diaphragms in radiographic equipment, in particular mammographs, is solved by using vibrating pots (10) mounted on a line (F) passing through the centre of gravity (G) of the diaphragm (8) corresponding to the direction of movement (F) to be imparted to this diaphragm. It is shown that much shorter exposure times can then be used. This is favourable to the repetition of radiographic examinations. <IMAGE>

Abstract: New process for obtaining sucrose derivatives modified in position 4' consisting in a) performing the esterification of all hydroxyl functional groups of the sucrose or substituted sucrose derivative starting material to give a perester of the said starting material; b) performing a partial hydrolysis, with the aid of a lipolytic enzyme, of the said perester from stage a) leading to a sucrose ester which has a free hydroxyl functional group in position 4'; c) performing any suitable reaction on the said free hydroxyl functional group in position 4' of the product from stage b) to obtain the desired sucrose derivative modified in position 4'. Stage b) of this process leads, in a simple manner and with a remarkable structural selectivity, to monoalcohols derived from sucrose which have a free hydroxyl functional group in position 4', which are intermediates in the synthesis of sucrose derivatives modified in position 4'. Sucrose derivatives modified in position 4' have advantageous properties such as, for example, a very high sweetening power in the case where the hydroxyl in position 4' is replaced by a halogen atom.

Abstract: A method and apparatus for preventing transmission of data packets with a greater intensity than a given value for the channel on any one of a number of channels on a common transmission link. A variable counter value (r) is associated with each channel. This counter value is increased for a given channel by a predetermined value (I) when a data packet arrives at this channel. The counter values (r) for all channels are decreased at uniform intervals by a value (d), which is less than the predetermined value (I). Data packets arriving at a channel, the counter value (r) of which exceeds a given limiting value (C) are rejected.

Abstract: On obtient un anticorps modifié par une toxine ou un fragment de cet anticorps en liant une substance susceptible d'induire chimiquement ou physiquement une toxicité contre les cellules humaines infectées par un virus avec un anticorps pouvant réagir spécifiquement avec un ou plusieurs antigènes dudit virus ou un fragment dudit anticorps par une liaison covalente via un support pharmaceutiquement inerte. Cet anticorps ou son fragment peut inhiber la prolifération des cellules infectées par le virus (cellules produisant le virus) même lorsqu'on l'utilise à faible concentration, et tue ces cellules sans inhiber la prolifération des cellules non infectées, tout en neutralisant efficacement le virus. On envisage d'utiliser cet anticorps dans le traitement d'infections virales chroniques telles que le SIDA et le syndrome apparenté au SIDA (ARC).

Abstract: Les détecteurs montés sur les pédales servent dans les véhicules à moteur à fournir un signal électrique en corrélation avec la position de la pédale d'accélération. Le signal électrique est ensuite utilisé par un régulateur moteur pour régler la quantité de carburant fourni au moteur. Certains de ces détecteurs produisent des signaux analogiques susceptibles de défaillances qu'un régulateur moteur ne peut distinguer de bonnes conditions de marche. Les détecteurs à distance sont difficiles à installer et à réparer. La présente invention concerne les détecteurs montés sur les pédales (10) munis d'un potentiomètre (52) et d'une plaquette de circuits imprimés (46) hermétiquement scellés et montés sur la pédale (14) afin de produire un signal modulé impulsion-amplitude dont le coefficient d'utilisation réagit en fonction de la position de la pédale.

Abstract: In an improved circuit module (9) with a flat chip-­carrying substrate (10) and cylindrical pistons (19) that contact the chips (12) for cooling, each piston has an axial bore (38) that carries a dielectric liquid to the chip and the lower face (23) of the piston (fac­ing the chip) is spaced away (22) from the chip to establish radial channels that carry the liquid across the surface (14) of the chip. The face of the piston, as seen in a section through the axis, is shaped to provide a selected flow pattern across the surface of the chip. The piston face reduces the channel height in the direction of flow where the liquid is non-boiling and thereby offsets the tendency for the flow rate to de­crease as the circumferential width of the channel widens. The piston face increases the channel height in the direction of flow where the liquid is boiling to handle the increase in volume caused by the vapor. In one embodiment, the piston carries a shroud (70) around the chip which causes the coolant to flow across the edge (71) of the chip to provide additional chip cool­ing and to impinge on the nearby region of the sub­strate that supports the chips to remove heat that flows from the chip to the substrate. 
     In one embodiment, the pistons are thermally conductive, and the temperature of the coolant at the inlet to the pistons is lower than the temperature required at the outlet to cool the piston. The pistons have fins that help to condense the vapor. In this embodiment, the lower face of a piston has radial fins that establish pie-shaped channels for the coolant to flow in. The fins (36) also provide heat transfer by conduction from the chip to the piston supporting structure (the "hat") (17).

Abstract: A high-speed electro-optical light gate (40) includes a pair of matched variable optical retarders (54 and 56) positioned between a pair of light polarizing filters (42 and 44) to promote rapid switching between optical transmission states for light rays of the wavelength to which the variable optical retarders are tuned. The projections (62 and 68) of the optic axes of the variable optical retarders are orthogonally aligned so that the response time characteristics of the transitions between optical transmission states of the light gate reflect only the turn-on time response characteristic of the variable optical retarders. A field sequential color display system (78) incorporates a switchable color filter (80) which utilizes the alignment configuration of the variable optical retarders of the light gate to provide light output states of white light and light of three different colors to form an image in full color.
