Abstract: Pharmaceutical compositions and methods of treatment are useful for treating myelosupression and viral infections associated with AIDS, particularly cytomegalovirus retinitis. Such compositions and treatments utilize an antiviral effective amount of 9-­(1,3-dihydroxy-2-propoxymethyl) guanine (DHPG) in combination with an anti-myelosuppressive effective amount of granulocyte macrophage colony stimulating factor (GM-CSF). The use of DHPG and of GM-CSF for the preparation of a pharmaceutical composition for use in this combination treatment as well as kits containing pharmaceutical compositions containing DHPG and GM-CSF are also disclosed.

Abstract: One embodiment of the transmission system comprises a transmitter with linear MSK modulator (1a) and a coherent differential MSK receiver (2a) which are connected by a transmission medium 3. A system according to the invention is essentially characterised by reception filters (21r and 21i) in the receiver including analog or digital equalizers, as well as by the differential encoding carried out on the symbols of a message to be transmitted (Me) by a differential encoder (11) included in the transmitter. The function of the equalizers is to eliminate, on reception, noise due to interference between the symbols. The differential encoding carried out is such that an encoded symbol of order k delivered by the coder depends on the corresponding symbol of the message and on the encoded symbol of order k-M, where M is an odd integer preferably greater than 1. On reception, the decision error probability relating to a received symbol is all the smaller the higher the integer M. The value M = 3 is an appropriate value.

Abstract: Dans un système d'injection de carburant pour un moteur à combustion interne, ledit système calcule la largeur d'impulsion des impulsions d'injection de carburant synchrones en angle provenant d'un capteur de charge principal, tel qu'un capteur de pression (22) du collecteur d'admission, ou un compteur de masse d'air (24) à film chaud ou à fil chaud. Dans des conditions de charge du moteur changeant rapidement, le signal provenant du capteur de charge n'est pas suffisamment précis pour maintenir un mélange étroitement stoïchiométrique. L'invention concerne un capteur d'angles d'étrangleur destiné à controller le degré d'ouverture d'un étrangleur (18) de moteur, ainsi qu'un moyen destiné à changer le calcul du signal d'injection du carburant synchrone en angle, lorsque la vitesse mesurée du changement de l'angle de l'étrangleur atteint une valeur prédéterminée. Le changement du calcul peut consister à modifier les caractéristiques de filtrage d'une fonction de filtrage appliquée normalement au signal de base d'injection de carburant synchrone en angle, à modifier l'échantillonnage du signal provenant du capteur de charge du moteur ou à dériver le signal de base d'injection de carburant synchrone en angle à partir du signal d'angle de l'étrangleur, et non à partir du signal du capteur de charge principal. En outre, on peut changer la compensation du changement de la charge par un calcul effectué à partir du signal de charge de l'étrangleur et non à partir du signal de charge principal. Le système peut également être agencé pour injecter une ou plusieurs impulsions intermédiaires d'injection de carburant asynchrone entre les injections normales synchrones en angle, afin de permettre au mélange de carburant/air d'effectuer un changement rapide en rappport étroit avec la charge du moteur.

Abstract: To ensure that such an actuator (17) has a linear response, the piston of its control valve must have zero valve lap with the fluid conduit to be controlled. However, manufacturing tolerances lead to negative valve laps and these lead to lost flows. In order to eliminate static friction and hysteresis, a dithering movement is imposed continuously on the control-valve piston of the actuator (17) the lost flow then depends on the magnitude of the valve lap and on the frequency and amplitude of the dithering movement. The dynamics of the actuator (17) are improved and the power loss limited by choosing a positive valve lap and raising the amplitude of this movement adaptively to the valve lap using an adaptation circuit (3).   <IMAGE>

Abstract: Detaching a cured tire from mold sections (12, 14) of a tire mold (10) during opening of the mold by com­municating air under pressure into the space between the mold sections (12, 14) and confining the air in this space with a sleeve member (32) supported on the upper mold sec­tion (12) and slidably urged into sealing engagement with the lower mold section (14). Air under pressure is then communicated from the space between the mold sections to the spaces between the cured tire surface and the molding surfaces of the upper and lower mold sections to detach the tire. Sealing rings (50, 60) on the sleeve (32) and on the upper mold section (12) prevent leakage of the air under pressure from the space between the mold sec­tion. Spring means (38) between the upper mold section (12) and the sleeve member (32) provide extension of the sleeve member (32) into sealing engagement with the lower mold section (14).
