Abstract: The switching of upper and lower switching elements (7,8) is controlled by respective upper and lower arm driving circuits (5,6). Those switching elements (7,8) are connected in series across a primary d.c. power source (1) and their successive switching generates a drive voltage which is applied to a load (9). A secondary d.c. power source in the form of a capacitor (4) is connected to the lower arm driving circuit (6) whilst the upper arm driving circuit (5) is connected to a further capacitor (2) connected to the high potential side of the primary d.c. power source (1). The capacitor (2) is charged from the secondary d.c. power source (4) through a charging circuit (3). The invention is particularly applicable to multi-phase driving circuits.

Abstract: Gases may be separated from liquids by permeation through a membrane comprising (i) vinyl alcohol cross-linked by an aliphatic polyaldehyde having at least three carbon atoms, or (ii) a silicone or silicone-polycarbonate. A pressure differential is maintained across the membrane between a high pressure charge side and a low pressure discharge side. 
     The process is especially suitable for separating acid gases (e.g. hydrogen sulfide or, preferably, carbon dioxide) from alcohols (e.g. methanol).

Abstract: Le dispositif de l'invention permet la distribution de doses de volume donné d'un liquide contenu dans un conteneur déformable. Il assure une sécurité renforcée. Il comporte notamment un organe de sécurité (5) déplaçable, monobloc, comprenant une partie supérieure de préhension (6) ayant une face de fermeture transversale (7), une partie médiane formant clapet (8) creuse, et une partie inférieure (9) formant coulisse et orifice de sortie également creuse. Cet organe de sécurité comportant ainsi un creux axial (10) est monté à coulissement axial sur la tubulure (1) par sa partie inférieure (9), entre deux positions extrêmes où il peut se trouver maintenu. Dans la position inférieure de fermeture où la partie médiane (8) de l'organe de sécurité (5) est active, il empêche alors le passage de liquide depuis le conteneur jusqu'à la cuvette via la tubulure (1) et ses trous d'amenée et de sortie (3). Dans la position supérieure d'ouverture où ce passage est rendu possible via des lumières axiales et latérales (11) de la partie inférieure (9) et le creux axial (10) avec lequel elles communiquent, la partie médiane (8) est alors inactive, la partie supérieure de préhension (6) de l'organe de sécurité (5) est saillante, en permanence, au moins partiellement, de la cuvette, l'organe de sécurité (5) étant tel qu'une fois le capuchon enlevé par l'utilisateur, ce dernier doit, pour pouvoir utiliser le dispositif de distribution de doses, faire passer volontairement l'organe de sécurité (5) de sa position inférieure de fermeture à sa position supérieure d'ouverture en actionnant la partie supérieure de préhension (6).

Abstract: A machine, by means of which seeds, especially cotton seeds not dehaired, can be moistened with liquid active substances. For this, the cotton seeds are separated in a feed and proportioning unit (2) comprising conveyor worms (12-15) and a baffle (22) and are introduced uniformly into a spray chamber (4). In the spray chamber (4) an atomiser (17) generates a fine spray mist and moistens the falling seed grains. The grains fall into a mixing and conveying space (10) and there are mixed by means of mixer and agitator shafts (24, 25). A conveyor worm (26) transports the seeds slowly to an outlet orifice (11) during the mixing operation.

Abstract: L'identité d'une unité (106) d'un abonné appelant est communiquée à une unité d'abonné appelé (ou plusieurs) (106') en demandant à l'appelant de s'identifier (112) à un central (102 et 104a-c) et de demander accès aux ressources de communication. Le central transmet l'identité de l'appelant à l'appelé (114), ce qui permet à l'appelé de décider de répondre ou de ne pas répondre à l'appel. Si l'appelé répond, une liaison de communication HF entre les deux abonnés téléphoniques est établie. Inversement, si l'appelé ne répond pas (ou répond négativement), l'appelant reçoit une indication ''occupé''. Eventuellement, le central peut fonctionner comme un système d'enregistrement de messages pour stocker des messages provenant d'appelants et destinés à des abonnés ne répondant pas (occupés). De cette manière, un appelant peut laisser un message pour que ce dernier soit pris par la suite.

Abstract: A coupling unit (10) mountable in the exhaust train of an engine immediately downstream of the exhaust manifold provides a significant reduction in engine noise levels. The coupling unit does not include a rigid liner but comprises a flexible tubular coupling (10) consisting essentially of inlet and outlet collar portions (18, 20) and an intermediate dual wrapped flexible central conduit portion (16). The flexible dual wrapped central portion (16) consists of a longitudinally undulating, pressure-carrying conduit member (26) and a concentric, vibration-dampening helicoidal covering (34). The flexible coupling (10) has a length to inside diameter ratio in the range of 1:1 to 8:1, and permits limited multi-axis movement of one of the collar portions (18, 20) relative to the other. The flexible metal coupling (10) is effective in reducing noise levels at engine speeds in the range of from idle speed up to about 5,000 rpm.

Abstract: Method of preparing a biologically degradable film, which film consists of synthetic polymer and biologically degradable polymer. In the met­hod small particles are made from said biologi­cally degradable polymer in a water suspension by means of enzymes that split and release small molecyles from the surface of the biopolymer particles. When the wished particle size is ac­hieved, vegetable oil is emulgated in the system and the particles coated with enzyme protein obtained in the step a) are coated with vegeta­ble oil at the same time as the act of degra­dation of the biopolymer particles by the enzy­mes are interrupted. The particles coated with oil obtained in the foregoing stages are separa­ted from the suspension to remove small molecy­les after which the particles are redried and thereafter pulverized. The final film is prepa­rated in a film extruder in which the biopolymer is mixed with the synthetic polymer and other additives that generally are used in a film.

Abstract: A process is disclosed for the production of a purified pigment, in which electrolyte ions and fine particles of the opposite polarity have been either completely or partly eliminated so that the purified pigment will not become a hard cake in a slurry state and will hardly undergo secondary aggregation even when dried. The purified pigment is obtained by bringing an aqueous dispersion of particles of the pigment into contact with an H-type cation-exchange resin or an OH-type anion-exchange resin, whereby counter ions are ion-exchanged to either lower or raise the pH of the aqueous dispersion. As a result, the dispersion stability of the pigment particles is destroyed, and only acidic or basic pigment particles are caused to sediment and are hence separated. A process for the production of a highly-classified purified pigment is also provided. An aqueous dispersion of pigment particles is used after con­ducting ion-exchange treatment and deflocculating the pig­ment particles. The aqueous dispersion is classified rely­ing upon differences in sedimentation velocity among the pigment particles. followed by ion-exchange treatment to destroy the stability of the aqueous dispersion.
