Abstract: A toothed belt drive consisting of a toothed belt and a toothed pulley engaging in the teeth of the latter, power being transmitted between the belt and the toothed pulley by the mutually contacting flanks of the teeth of the respective part of the toothed belt drive, is to be configured in such a way that the relatively high shear forces which occur when a high power is transmitted can be absorbed without premature damage to the toothed belt. 
<??>For this purpose, the invention provides that the belt teeth are each provided with an approximately conically tapering recess which starts from their top surface and the mutually facing walls (5a, 5b) have a curvature which corresponds to the curvature of the outer flanks of the belt tooth (3a, 3b), the size (G) of the recess allowing the inner walls of the recess to be designed as power-transmitting flanks, and a correspondingly designed projection of the belt pulley, the said projection being arranged between two pulley teeth, in each case engaging in the recess.

Abstract: A slit valve apparatus (10) associated with an aperture (14) in a chamber wall (12) through which a semiconductor wafer may be passed along a transfer plane (20). The apparatus (10) is characterized by a valve seat (22) which is angled relative to the transfer plane (20) and a door (28) which moves linearly along an axis (54) substantially perpendicular to the valve seat (22). All frictionally engaged parts of the slit valve assembly (10) are isolated from the interior of the chamber (48) by a bellow sleeve (46) to reduce the formation of particulates. The method is characterized by the steps of surrounding the aperture (14) with a first seating surface (24) defining a sealing plane (26) which is angularly disposed with respect to the transfer plane (20) and engaging or disengaging a second seating surface (30) with the first seating surface (24) by linearly moving the second seating surface (30) in a direction perpendicular to the sealing plane (26).

Abstract: A dynamic pressure bearing (4) equipped with a moving side bearing member (4b) and a fixed side bearing member (4a) and rotatably bearing a rotor (1) by generating a fluid dynamic pressure between the moving side bearing member and the fixed side bearing member is disclosed. 
     The dynamic pressure bearing includes exciting means (6) for applying a high-frequency vibration to the fixed side bearing member (4a) at the time at least of start-up or shutdown of the rotor. By this, both bearing members (4a,4b) are kept almost free from contact with each other and a frictional resistance at start-up and/or shutdown is minimized.

Abstract: An open reading frame from the DNA which codes for interleukin-2 (IL-2) is suitable for preparing fusion proteins. A part-sequence of the DNA which corresponds approximately to the first 100 amino acids of IL-2 suffices for this. The gene for the required protein can be placed upstream or downstream of the open reading frame. The resulting fusion proteins are sparingly soluble or insoluble and can easily be separated from the soluble proteins intrinsic to the host.

Abstract: L'invention permet la fusion nucléaire des deutérons et des lithons. On expose un réseau cristallin (14) possédant des lacunes octaédriques alignées avec un champ électrique (24), sur une première surface, à une solution électrolytique d'eau lourde et de deutéroxyde de lithium, laquelle solution est contenue dans un canal (22). Des atomes de deutérium et de lithium provenant de l'électrolyte sont absorbés par la structure cristalline et leurs électrons sont dépouillés afin de produire des deutérons et des lithons, ces derniers gardant deux électrons. Sous l'influence du champ électrique, des deutérons se frayent un chemin à travers le réseau et se rassemblent dans les lacunes de sorte qu'ils forment un réseau de deutérure de palladium (la phase beta du palladium). On introduit une barrière, qui peut comporter une électrode (12) sur laquelle est déposé le réseau cristallin, afin qu'elle forme la limite du réseau de manière perpendiculaire au champ électrique pour empêcher un passage ou une diffusion supplémentaire des deutérons à partir des lacunes contiguës à la barrière. Le chauffage de la solution électrolytique augmente le chevauchement entre les énergies des particules diffusées et les niveaux énergétiques de la résonance de transmission spécifiques au réseau de deutérure métallique et aux particules qui s'y diffusent. Ceci favorise la diffusion des deutérons et des lithons de l'électrolyte dans le réseau afin d'augmenter la probabilité des réactions thermonucléaires entre les particules diffusées et les deutérons qui se trouvent déjà dans les lacunes du réseau. On extrait du réseau cristallin la chaleur générée par les réactions thermonucléaires et on l'utilise pour la production d'énergie.

Abstract: Procédé d'hydrolyse sélective de triglycérides en mélanges de 1,2 ou 2,3-diacyle glycérides et 2-acyle glycérides. Le procédé utilise un alcool d'alkyle choisi dans le groupe comprenant 2-méthyl-2-propanol, 2-butanol et les alcools d'alkyle à chaîne ramifiée ou droite primaire, secondaire ou tertiaire contenant 5 à 8 atomes de carbone, ainsi que leurs mélanges, dans un système tampon aqueux et une 1,3-lipase. On estérifie les 2-acyle glycérides se trouvant dans le mélange afin de produire des 1,2-diacyle glycérides ou des 2,3-diacyle glycérides stéréospécifiques à l'aide d'anhydrides d'acide et d'un catalyseur de lipase. Etant donné les conditions de réaction, on constate peu de redisposition des diacyle glycérides dans le mélange et moins de 20 % de triglycéride sont formés. On peut obtenir des 1,2,3-triglycérides stéréospécifiques à partir de ces matières par des réactions d'estérification classiques dans des conditions permettant la régulation de la redisposition.
