Abstract: Mecanisme reducteur de vitesse fonctionnant comme un dispositif de vis-sans-fin et roue tangente forme par un arbre (1), des rouleaux filetes (2), le tout dans un boitier (5) muni d'une ouverture permettant l'acces de la roue tangente (4) dont les dents engrenent avec des filets (3) dont sont munis les rouleaux filetes (2). Les rouleaux filetes (2) tournent autour de l'arbre (1) des que celui-ci est mis en rotation. Les filets (3) agissent sur les dents inclines ou non de la roue tangente (4) soit par leur propre inclinaison, soit par le decalage des filets (3) en passant d'un rouleau au suivant. Ce mecanisme permet d'obtenir une precision meilleure dans la transmission de la rotation, un travail sans jeu aucun parce qu'il est possible de le precontraindre dans l'axe horizontal et vertical. Dans un meme encombrement il est aussi possible d'obtenir une gamme tres large de rapports de reduction, gamme se composant de nombres rationnels qui ne doivent pas etre necessairement des nombres entiers. Un tel mecanisme peut trouver son utilite dans un grand nombre de cas ou un reducteur vis-sans-fin/roue tangente etait utilise jusqu'alors, particulierement les cas ou une tres grande precision et un haut rendement est demande.

Abstract: Processeur d'images de trames et procédé permettant de générer des balayages récurrents binaires à partir de commandes d'entrées symboliques. Le processeur est particulièrement approprié à une utilisation dans un système de gravure au laser commandé par ordinateur tel qu'un clicheur au laser, un générateur de dessins-modèles pour des circuits imprimés, ou un copieur intelligent. Des données descriptives pour les caractères qui constituent une image de sortie sont générées par un ordinateur et stockées dans une mémoire de caractères, et des commandes d'entrées symboliques qui pointent sur l'adresse des données descriptives dans la mémoire de caractères sont générées par l'ordinateur et stockées ligne par ligne. Au fur et à mesure que le rayon de sortie balaye le support de sortie, les données descriptives pour chaque caractère successif à mettre en image sont extraites de la mémoire de caractères et traitées pour produire des données de sortie sérielles de modulation du rayon de sortie.

Abstract: In order to boil eggs or other foods not suitable for cooking with direct microwave radiation, a receptacle containing such foods is separated from a microwave source by a radiation shield overlain by a heating vessel partly filled with water which is exposed to the microwaves. This vaporizes the water and the resulting steam is admitted through one or more tubes into the receptacle for a rapid heating of its contents. The shield may reflect the incident microwaves into the water bath.

Abstract: An automatic pig-charging apparatus for hot-chamber pressure-diecasting machines is described, which enable small parts to be manufactured e.g., a Zamak alloy especially under mass production conditions. Excessive fluctuations of the level of the liquid metal melt have prove to have disadvantageous effects on the quality of small parts, and on the service lives of the pressure-diecasting machines and dies. The aim must accordingly be to minimize the fluctuations. The present invention provides a control system, which keeps the liquid metal level within narrow limits. A float switch automatically triggers a charging operation whenever the lower liquid metal level is reached. This operation involves the automatic replenishment of the liquid metal melt by addition of pigs supplied from a replenishing station.

Title: Method and apparatus for constructing multiple layer corrugated board containers
Inventor: GILLARD DAVID F
IPC: B31B50/34
Filed: 1982-10-14
Abstract: A method and an apparatus is disclosed for forming a multi-layered container of compressible sheet layers (10), such as corrugated board. The containers are formed in a single operation and avoids the known techniques of folding the layers (10) before laminating in multistep methods. Furthermore, the container may be foldered without the layers separating. The method of forming a multi-layered container having a plurality of flat sides with corners between adjacent sides comprises winding compressible sheet layers (10) on a forming mandrel (14). In the process, one edge of a layer (10) is attached adjacent to a corner of a mandrel (14), a shoe plate (15) applies pressure to the layer (10) against the mandrel (14) as it rotates to maintain a substantially constant pressure and tension on the layer (10). An additional momentary force is applied to the shoe plate (15) as each corner of the mandrel (14) passes over the shoe plate (15) such that the layer at each corner is compressed.

Abstract: A combined lubrication and brake actuating fluid system for a drive axle, separate from the transmission hydraulic system of the vehicle, utilizes the differential housing (32) as a reservoir and uses the extreme pressure gear lubricant therein as the operating fluid. A pump (150) distributes the gear lubricant through a pressure balanced spool valve (156), responsive to a brake pedal controlled pilot pressure valve (168) associated with the transmission hydraulic system. The spool valve (156) has ports (158 and 162) communicating with the brake pressure inlet (100) and lubricant inlet (126) of the drive axle. The brake port (158) is permanently connected to the spool valve inlet (154) and the lubricant port (162) is normally connected to the spool valve inlet. When the brakes are applied the spool (172) temporarily isolates the lubricant port (162) from the spool valve inlet (154) to apply the entire flow from the pump (150) to the brakes.

Abstract: The hearing aid (1) comprises a case to which a line (4) is connected. In a known connection of this type, it is disadvantageous that it is complicated to establish the connection and that the connection can be detached by a tensile stress on the line. In this respect, the invention provides a connection holder (5) which is a self-impeding hook, the contacts (38 to 40) of which, when hooked onto the case, engage contacts (30 to 32) of the aid (1) which are attached there. A connection according to the invention is particularly suitable for use in connecting behind-the-ear hearing aids with hearing training devices or connecting other devices (radio, television set and so forth) generating electroacoustic signals. <IMAGE>
