Title: Piperidyl- and benzoate-based stabilizer system for polyolefin pigmented fibers and thin films
Inventor: KLETECKA GEORGE
IPC: C08K5/3435
Filed: 1992-02-11
Abstract: PIPERIDYL- AND BENZOATE-BASED STABILIZER SYSTEM FOR     POLYOLEFIN PIGMENTED FIBERS AND THIN FILMS                   ABSTRACT OF THE DISCLOSURE Excellent color stabilization as well as integrity is obtained in thin film and fibers exposed to bright sunlight at relatively high temperature, in polyolefin (PO) articles pigmented with blue and green phthalocyanine, and red azo and disazo pigments. The pigment is combined with two 'large molecule' primary stabilizers, the first a piperidyl-based (PDYL) hindered amine light stabilizer (HALS), and the second, a 3,5-disubstituted-tert-butyl-4-hydroxybenzoate (3,5-DHBZ). The first contains at least two polysubstituted piperidyl rings in its molecule; the second is a hindered phenol with an ester group in the para- position. Stabiliz-ation of the PO's color is obtained for as long as the PO articles themselves are stabilized by the combination of primary stabilizers, typically, their useful life. With the combination, the pigmented articles are not only thermo-oxidatively and light-stabilized, but there is exceptionally low color fade. Because fibers may be extruded twice for better distribution of pigment, a small amount, no more than 0.1 phr of secondary melt-stabilizers, may be used. Blue-green- and red pigmented PO articles exhibit less than a ?3 change in color (color fading) due to degradation of the pigment, over a period of exposure resulting in absorption of 1240 Kjoules/m2. Such exposure of pigmented articles, deemed equivalent to normal outdoor use over a period of more than 10 years, results in essentially no visible loss of color due to degradation of the pigment.

Title: Etirement de fibres discontinues
Inventor: PHILLIPS DAVID G
IPC: D01H5/22
Filed: 1990-08-16
Abstract: Un procédé pour étirer un ensemble, par exemple un ruban ou une mèche, de fibres discontinues non retordues (12), afin de réduire leur diamètre et d'accroître leur longueur, met en oeuvre une fausse torsion pour permettre une friction entre les fibres en vue d'assurer la réalisation d'un étirage des fibres et non d'un étirage de l'ensemble. Les fibres sont premièrement plastifiées par traitement avec un agent approprié dans un bain (16) puis elles passent dans un appareil utilisant un certain nombre d'agencements rotatifs (24, 25, 29, 32) de galets menés (26, 33). Ces agencements sont montés pour tourner entre deux points de contact de blocage pour le tordage (18, 18') et sont rotatifs autour d'un axe longitudinal correspondant au sens de déplacement de l'ensemble dans l'appareil pour imprimer une fausse torsion dans ledit ensemble. Ce dernier est étiré entre deux des agencements de galets (24 et 25), les galets de l'agencement aval (25) étant entraînés à une vitesse supérieure aux galets de l'agencement amont (24). L'étirage est ensuite fixé par chauffage à la vapeur dans une chambre (17) tandis que la fausse torsion est maintenue par d'autres agencements de galets rotatifs (29). Des étapes de traitement ultérieur (14, 46) peuvent être ajoutées pour stabiliser davantage les fibres étirées. Les fibres sont des poils animaux, par exemple de la laine.

Title: Absorbable anastomosic fastener means
Inventor: MILLER MICHAEL B
IPC: A61B17/115
Filed: 1992-06-01
Abstract: ABSTRACT          A mechanism which is capable of anastomosis of two lumens by an absorbable fastener.  The fastener is made from two washer-like plates. One such plate has holes to receive latching prongs protruding from the other plate. Fastening is done through a single linear motion that causes the prongs to pierce the tissue, latches the prongs into a receiver and causes a knife blade to cut through excess fastener material and tissue.  The ease of removal, by pulling the mechanism thorugh the formed anastomosis, is greatly enhanced.  The system can be used such that the plates can be placed in any configuration to properly anastomose tissue.

Title: Device for ejection of ground coffee pressed into a cake from a brewing apparatus of a coffee machine
Inventor: LUESSI ANDRE
IPC: A47J31/24
Filed: 1992-07-28
Abstract: The ejecting device comprises an ejector (17) which is pivotably secured to an infusion cylinder (9) arranged to move along a parallel drive spindle (6) and a lug (22) arranged towards the bottom of a side-membee (2) of a frame (I). A second piston (8) arranged to move in the infusion cylinder (9) can be moved to the upper end of said infusion cylindee (9) as the latter moves downwards. A compressed block of ground coffee (40) is forced out of the infusion cylinder (9) during the movement. It lies on the convex surface (42) of the second piston (8). The ejector (17) comprises two pivoted levers (18, 19) extending along the infusion cylinder (9) and beside it. In the lower region of the infusion cylinder (9) they are pivotable about an axis (23). The ends of the pivoting levers (18, 19) away from the axis are connected to an ejector plate (20). One of the pivoting levers has an L-shaped extension (21). This co-operates with the lug (22) as an actuator to cause the ejector (17) to pivot outwards. Because both one end (41) of the infusion cylinder (9) and the surface (42) of the second piston (8) are convex and mutually matched in such a way that a sliding surface (50) of the ejection plate (20) passes across the surfaces (41, 42) virtually without any gaps when the ejector pivots, the compressed block can be stripped off without any significant quantity of grounds' being left behind.

Title: Door lever handle arrangement
Inventor: QUAM GARY L
IPC: E05C3/12
Filed: 1993-05-18
Abstract: Abstract of the Disclosure The arrangement includes an elongated base mount housing having a front wall and a mounting surface defining between them a hollow interior.  A lever arrangement includes a connecting member which has a driver extending from one end thereof.  The driver extends through an opening in the front wall and into the hollow interior.  A pivotable lever extends at right angles to the  second end of the connector.   A detachable plate mounting a spring is mounted in the interior surface of the mounting wall in the hollow interior and in alignment with the driver.  The ends of the spring are bent to form spring engagements, and the driver includes fingers for  engaging  the  spring  engagements.    Thus,  when  the pivotable lever is pivoted from an initial position at right angles to the elongated base mount, the driver rotates with the pivotable  lever  and,  because  the  fingers  engage  the spring  ends,  the pivotable  lever  is  pivoted  against  the tension of the spring during its pivoting motion.  When the pivotable lever is released after pivoting, the tension of the spring, acting on the fingers of the driver through the spring  ends,  returns  the pivotable  lever  to  the  initial position.
