Abstract: A fuel pumping apparatus of the rotary distributor type includes a spill passage (20) connected with the bore (12) which houses the pumping plungers (9). A seating (22) is defined about the spill passage and a valve member (23) is provided for cooperating with the seating. A piston (25) is coupled to the valve member and is slidable in a cylinder (21).

Abstract: The invention relates to civil engineering. It is concerned with a method for making a trench by the technique of a wall cast in the ground, according to which a wall (10) cast in the ground and surrounding the trench to be made is produced, and then the trench is made by installing boards at various levels of the trench which perform the function of stays for the said wall, characterised in that boards (1) consisting of prestressed board elements are installed, and in that, after said installation, the prestress applied to said elements is released in such a way that said elements exert on the cast wall a counterthrust opposed to the thrust exerted on said wall by the ground. The invention makes it possible to reduce the thickness of the cast wall. <IMAGE>

Abstract: A device for making grooves in the surface of workpieces has a bearing part (1), on which are arranged deflecting devices for a roller chain (6) which consist of rotatably mounted chain wheels (2') and of sliding shoes (2'') having a curved guide surface (5). At least one of the chain wheels (2') is driven, with the result that the roller chain (6) is offset in rotary movement. The run of the roller chain (6) in its plane of movement is determined by the design and arrangement of the deflecting devices (2', 2''). Material-removing tools (7) project from the roller chain (6) perpendicularly to the plane of movement of the latter, by means of which tools grooves having a curved path are made in the surface of a workpiece. The configuration of these grooves can be varied, as desired, by the design and arrangement of the deflecting devices (2', 2''). <IMAGE>

Abstract: Aménagement de circuits donnant des accès multiples (11-18) à une très grande base de données dans laquelle se trouvent plus de dispositifs de mémoires (28) qu'un seul tampon de sortie peut entraîner. Les portes d'accès multiples donnent accès à des données allant vers la mémoire ou venant de celle-ci, qui passent par un point d'étranglement (22) comprenant au moins un bus de lecture de données (24) et un bus d'adresse (23). Le flux de données et de signaux d'adresse est acheminé vers le système, lesdits bus de données d'adresse se reliant aux dispositifs de mémoire, par l'intermédiaire d'un système de bus disposés en pyramide ou branchés (42) en une pluralité d'étapes de manière à créer un système arborescent de tampons. Ledit aménagement peut se relier à une mémoire morte; pour la connexion à une mémoire vive (28) le point d'étranglement comprend en plus un bus d'écriture de données séparé (25) et au moins un fil de contrôle de logique (23) aménagés de façon à acheminer également le signal de commande. De cette manière on réalise l'acheminement des données et des signaux d'adresse et de commande à travers les bus, de préférence de telle manière que les signaux qui commandent l'acheminement sont décalés d'un retard semblable à celui inhérent aux données. Ledit retard des données, des bus d'adresse et de contrôle et/ou des signaux qui commandent l'acheminement est obtenu par l'utilisation de registres de décalage commandés par une horloge de haute fréquence.

Title: Badk-up safety device and method.
Inventor: MIELE JOSEPH R
IPC: B60T7/22
Filed: 1990-04-18
Abstract: The device senses the impact of a vehicle backing into an object, and automatically applies the brakes of an ordinary hydraulic brake system to stop the vehicle very quickly, before any significant damage can be done. The device uses a pneumatic cylinder to quickly and powerfully pull on the brake pedal of the vehicle when the vehicle is in reverse gear and an impact is sensed. A small, light-weight and relatively inexpensive air compressor which runs off of the battery of the vehicle and a reservoir are used to supply the air cylinder. The brakes stay in the actuated condition until the vehicle is taken out of reverse gear; then the air cylinder is vented to atmosphere automatically, and the brake pedal is released to return it to its initial position and enable the normal operation of the vehicle. The device can be supplied in the form of a kit to be used to easily modify existing vehicles without invading the hydraulic brake lines or vacuum system of the vehicle.

Abstract: Un système de construction en briques moulées et en ossatures porteuses légères sert à construire des bâtiments écologiques, ayant notamment des grandes ouvertures entre les appuis. Ce système de construction convient à la préfabrication industrielle d'éléments de paroi individuellement dimensionnables en briques à coques de support en sable calcaire qui peuvent être pré-empilées à sec par un robot à commande numérique par calculateur et montées ultérieurement dans l'usine ou sur place, même par des ouvriers non spécialisés, par exemple par des bricoleurs, des sections de paroi ayant plusieurs mètres carrés pouvant être mises en place avec un seul accessoire de levage. Les briques sont ensuite remplies avec une armature, des conduits et du béton, du plâtre, de l'argile ou similaire. En particulier, on peut intégrer dans les parois internes des conduits de chauffage ou de refroidissement et dans les parois externes des conduits d'absorption, la masse des parois et des fondements pouvant servir de surface de chauffage par rayonnement et/ou de masses d'accumulation. L'ossature porteuse légère comprend des tôles rigides dans plusieurs sens et/ou des barres de treillis, notamment en acier de construction soudé à la machine. L'invention concerne finalement des éléments de liaison des éléments de construction et des dispositifs de fabrication de ceux-ci. Ce système de construction permet de construire avec des matériaux écologiques d'une manière rapide qui économise l'énergie et les matériaux, et est donc peu onéreuse.

Abstract: 5 n7 The production of an active Pseudomonas glumae lipase isolated from P. glumae PG1 (CBS 322.89) and other lipases suitable for application in detergent systems is described in homologous, but particularly in heterologous hosts, e.g. Bacillus subtilis. For the latter a "helper function" or "lipase-specific stabilization/translocation protein" is needed, for which a gene is provided which, when expressed in concert with the lipase gene, can improve the stabilization of the intermediates involved in the production and translocation/secretion of the lipase. The hosts are transformed by recombinant DNA methods and modified lipases can be made by site-directed mutation or classical mutation techniques. The lipase gene and the gene encoding the helper function can be part of one operon that can be transcribed to form a polycistronic messenger or be present as separate genes yielding two mRNA's on transcription. The production level can be further improved by optimising the regulation sequences. It can be advantageous to use at least part of the signal sequence of the lipase gene in addition to a signal sequence homologous to the host in which the lipase is produced.

Abstract: A roller leveller comprises a raisable upper work roll group (14), and a lower work roll group (16), between which strip material is passed longitudinally along a first path, to be surface levelled by the rolls of the upper and lower groups. The upper and lower work roll groups are arranged in a zigzag form so that the axes of three work rolls (18, 32) adjacent to each other at upper and lower sides and three points of intersection with the plane crossing these axes may make three vertexes of an isosceles triangle (T, T'). Additionally, the lower work rolls at either the odd or even number positions in the lower work roll group are raisable to produce a second path for strip material between solely the rolls of the lower roll group. The second path typically can process strip material of greater thickness than the first path.
