Patent WO-9912594-A1 (WO)
Title: Gaine d'aiguille et seringue
Inventor: MOBBS WILLIAM LEONARD
IPC: A61M5/32
Filed: 1998-09-11
Abstract: L'invention concerne des gaines d'aiguille s'utilisant avec des seringues, comprenant un embout reliant un tube porteur flexible à une aiguille à usage médical. Les extrémités avant normalement ouvertes de la gaine peuvent être fermées une fois que l'aiguille et l'embout y ont été insérés par le tube porteur. Selon un exemple, (figure 4c), une gaine (10) présente une paroi latérale supérieure (24a) rigide en U inversé et une paroi latérale inférieure (26b) flexible qui s'ajuste dans la paroi latérale supérieure et est inclinée de manière élastique, afin que son extrémité avant (31) entre en contact avec celle (30) de la paroi latérale supérieure (24b), de manière à obturer l'ouverture avant de la gaine une fois la seringue (16) rentrée dans ladite gaine. La paroi latérale inférieure (26b) peut être bloquée ou clipsée dans la paroi latérale supérieure (24b) par pression de cliquets (72) au moment où la paroi latérale inférieure passe. L'aiguille se trouve ainsi entièrement enfermée de manière sûre après utilisation, afin de réduire le risque de blessure par piqûre d'aiguille et de contamination par projections de sang.

Title: Method and device for the extraction of blocks from a rock formation
Inventor: ANTUNES CACIQUE GERALDO
IPC: B28D1/00
Filed: 1992-07-16
Abstract: Extraction from rock formation of blocks of rock that are already of a paralellepiped shape and thus do not require final time consuming finishing operations involves cutting a long slot in the formation beneath a slice of rock to be removed and then drilling various orthogonal series of parallel aligned perforations to define cutting surfaces that are separated using metal plugs applied to the perforations. In this manner parallelepiped shaped small blocks are obtained directly and can be removed from the formation in a stage virtually ready for commercialisation. Equipment in the form of an extractor (1-28) permits the simultaneous formation of the slot and the perforations.

Title: Ammunition units
Inventor: GUSTAVSSON LENNART
IPC: F42B14/06
Filed: 1989-10-05
Abstract: ABSTRACT OF THE DISCLOSURE    The disclosure relates to an apparatus which makes possible the loading and automatic firing in a weapon of an ammunition unit provided with a sabot (2a), without consequential deterioration of the ballistics of the ammunition unit. The apparatus comprises a unit consisting of a number of prismatic or cuneiform elements which together form a rotationally sysmetrical body (3a) with an external  surface (3a'). This surface is truncated or curved and flares  rearwardly from its leading portion. The apparatus also comprises a device (3b) enclosing these elements at the trailing portions of the body (3a), and unifying the elements on loading of the ammunition unit into the barrel of the weapon. The device also encloses the leading portions of the sabot. This device (3b) is arranged  to  burst  on movement  of  the ammunition  unit  in  the barrel.  The elements will  namely execute flip movements about their trailing portions which are defined by the inner wall of the barrel  and  entail  that  the  rotationally  symmetrical  body  is splayed forwardly, which facilitates parting of the elements with the aid of aerodynamic forces on departure of the unit from the barrel.     Publication figure: Fig. 7.

Inventor: WILLIAMS DOUGLAS P
IPC: A47K3/00
Filed: 1990-07-30
Abstract: ABSTRACT      An improved bathtub with a door for easy access by older and physically handicapped persons is disclosed. The bathtub includes an entrance wall with an opening which conforms to the shape of the door, and a front wall adjacent to the entrance wall.  A seat is located in the tub with the forward edge of the seat located so as to provide a leg space between the seat and the front wall of the tub.  The front edge of the door is attached adjacent to the front wall of the bathtub by means of a double axis hinge.  When the door is opened, its front edge is guided directly inwardly in the tub by means of a tracking mechanism and the rear edge moves forward without any significant inward movement. In the fully opened position, the door is parallel to the front wall.  The door is so configured that during movement it does not swing over the seat, and an occupant of the tub can be seated while the door is moved between its closed and open positions.  The door contains a locking mechanism which can secure the door in a closed position.  The door can also be secured in an open position, providing stable support for a person entering and leaving the bathtub.

Title: Method and apparatus for forming a porous glass preform
Inventor: ABBOTT JOHN S
IPC: C03B37/018
Filed: 1991-01-23
Abstract: A method and apparatus for rapidly forming a porous glass preform is provided in which an array of burners is oscillated along a path parallel to the longitudinal axis of the preform. Unlike existing soot deposition techniques, the oscillation amplitude is limited so that each burner deposits soot on only a portion of the preform, e.g., 20% of the preform.      By controlling inter-burner variability and the air flow in the burner-array/preform region, preforms having substantially uniform axial properties are obtained notwithstanding the fact that different burners are used to laydown different parts of the preform.

Abstract: A wobble plate type refrigerant compressor having a lubricating mechanism provided at a ball-and-socket joint between a wobble plate and a piston rod is disclosed.  A wobble plate type refrigerant compres-sor includes a compressor housing having a cylinder block.  A plurality of cylinders are formed around the periphery of the cylinder block and a piston is slidably fitted within each of the cylinders and is recipro-cated by a drive mechanism.  A crankcase is formed between the cylin-der block and a front end plate of the compressor housing.  The drive mechanism includes a drive shaft, a rotor fixed to the drive shaft and a wobble plate disposed on an inclined surface of the rotor.  The piston rod connects the wobble plate to the piston.  A ball at one end of the rod is received in a socket formed at the wobble plate to form a ball-and-socket joint.  A hole is formed at the wobble plate to link one end surface of the wobble plate to the friction surface of the ball-and-socket joint.  A pair of grooves extending from one opening of the hole and terminating near the outer periphery of the wobble plate are formed at one end surface of the wobble plate.  Thereby, the lubri-cating oil adhering to one end surface of the wobble plate is effectively led to the friction surface of the ball-and-socket joint.
