Abstract: It consists of an electrical connector with a "U" shape, having its upper wings (8) folded downwards, and provided with grooves (17) in its lower inner part (11), having a plurality of transpassing holes (9) which are coplanar with holes (9) provided in wings (8) and the internal body (21) is capable of housing in holes (9) a conductor (3) that intersects the holes (9) and comes to rest on latch (7) and (23) through its central slot (10) which, on being intersected by conductor (3), is ready to receive conductor (4), that is housed in the lower part (11) where it lays itself over retaining grooves (17). In this manner when the wedge (18) with grooves (19) is pressed downwards, it causes a rotational movement around the conductor (3) causing the eccentric part (12) to position itself between the conductor (4) and the slot (10) that compresses the conductors against the connector (A). The lower convex part of the eccentric part (12) is provided with grooves (16) that ensure the latching and the electrical contact of conductors (3) and (4) with the connector (A). The latch (23) actuates over the conductors in the same manner, but obtains through the movement of the lever exerted by the pliers (24) during its application over the wings (25) a force or pressure several times larger than the force of latch (7), and is recommended for connections of cables that demand a contact pressure and a spring effect with high and constant force.

Filed: 1995-07-27
Abstract: A stand-alone takeaway and correction conveyor system for a food loaf slicer or other food product machine that produces groups of food products that must be held to close tolerance as to weight or some other readily measurable characteristic includes two conveyors, one for reject groups and one for acceptable groups.  The two conveyors are mounted on one base, in spaced parallel relation to each other, with the reject conveyor above the accept conveyor.  Both conveyors are driven, at related speeds, from one drive; the drive is mounted in the base and is energized and controlled, as to speed, from the food product machine.  The conveyor for acceptable groups has a pivotal outboard section to allow for service of packaging equipment without moving the system.          Both conveyors have eccentric mounts to compensate for large elevation differences in packaging equipment.  A correction tray is used for correction of reject groups of food products.  Controls on the base enable an operator to stop the food product machine and the conveyors and to jog the reject conveyor.

Inventor: DILENGE ANGELO
IPC: A61L2/26
Filed: 1994-03-24
Abstract: The invention at hand relates to a micro-filter disc based on kieselguhr, also known as diatomaceous earth, particularly for a complete sterilization of water. The micro-filter disc contains at least two kinds of silicately bonded kieselguhr at least one of which is pre-calcined and later burnt or sintered. The micro-filter disc has pore sizes in preferred magnitudes of 0.1 to 0.3µ whereby bacteria are mechanically and safely retained. A method is disclosed making possible the use of three kinds of kieselguhr and kaolin in connection with a careful drying and sintering thereafter. Thereby, it is possible to produce discs having diameters larger than 35cm and a thickness of 1 to 1.5cm. Such discs can be cleaned by way of rotating brushes slightly scraping off the discs. This enhances a simple construction of self-cleaning filter installations. The thus constructed filter installations require very little service and can be serviced by inexperienced operators.

Abstract: L'invention se rapporte à un compresseur du type à turbine utilisable dans un appareil à laser à gaz pour mettre en circulation un gaz le long d'un tracé d'écoulement du laser, un agencement d'étanchéité étant placé autour d'un arbre d'entraînement du compresseur pour empêcher les substances indésirables de migrer vers la turbine du compresseur en longeant l'arbre d'entraînement de ce dernier et de contaminer ainsi le gaz du laser comprimé par ladite turbine. Cet agencement d'étanchéité comprend un premier joint étanche, constitué de préférence par un joint à dépression, destiné à former une jointure d'étanchéité autour de l'arbre au moins pendant sa rotation, et un second joint étanche constitué par une vessie élastique qu'on déploie et contracte sélectivement pour la mettre en contact étanche et hors de contact étanche avec l'arbre d'entraînement, respectivement pour, d'une part, exercer une force d'étanchéité contre l'arbre, lorsque celui-ci est immobile pendant le pompage du laser et, d'autre part, éloginer la vessie de l'arbre, lorsque celui-ci est en rotation. Un tel agencement d'étanchéité est fiable et relativement économique et utilise moins de gaz que les agencements d'étanchéité de la technique antérieure.

Title: Single-piece self-guiding high mill plug
Inventor: NERY VICTOR WILLIAM
IPC: B21B25/00
Filed: 1996-01-03
Abstract: A single-piece self-guiding, high integrity high mill plug for producing seamless tubular steel products in rolling mills is provided. The high mill plug is produced from a single a casting having a substantially bullet shape with an opening at each end and a passage therebetween to allow gases which develop during the casting process to escape. By designing the high mill plug to be produced from a single casting with no dead-end cores, the latent surface defects associated with the prior multi-piece casting designs are substantially avoided and the casting used to produce the single-piece self-guiding high mill plug has a very high integrity. The single-piece self-guiding high mill plug substantially improves rolling mill operations for producing seamless tubular steel products by eliminating both time and labor expenses associated with disassembling and reassembling the worn work plug sections as required by the prior art multi-piece high mill plug designs.
