Filed: 1996-06-05
Abstract: A strip (10) for attaching a document to a binder without punching openings in the document or for reinforcing a document around openings formed in the document through which the document can be mounted in a binder. The strip (10) comprises an elongate layer (11) of thin flexible material, and a coating of repositionable pressure sensitive adhesive (20) on one major surface (12) along an inner edge portion. That layer is free of adhesive on both of its side surfaces along an outer edge portion. That outer edge portion is visually distinctive, and the juncture between the inner and outer portions is straight and visibly distinctive. The strip (10) has at least one opening through its outer edge portion adapted to receive a portion of a binder so that a document to which the coating of adhesive (20) along its inner edge portion is adhered with the edge of the document along the juncture between the inner and outer portions can be bound in the binder without punching the document, or, alternatively, so that a punched document having a through opening by which the document is bound in a binder can be reinforced by adhering the coating of adhesive (20) to the document with the opening in the outer edge portion in alignment with the opening in the document.

Inventor: WEIHRAUCH GEORG
IPC: A46D1/00
Filed: 1996-09-04
Abstract: The invention relates to a method for the manufacture of spiral bristles by extruding monofilaments. In order to provide a method with which spiral bristles can be inexpensively manufactured in the same way as conventional bristles with an identical, predeterminable quality, a monofilament having a non-circular cross-section is extruded and is prestretched after drawing off, accompanied by a reduction in its cross-section, followed by further stretch-ing, twisting to a spiral bristle material over at least part of its length and then stabilization by shrinkage. It is possible to extrude a monofilament with an oval or polygonal cross-section or having a core and at least one axially parallel rib. According to a further method, at least two monofilam-ents are prestretched on drawing off, accompanied by a reduction of their cross-section, followed by further stretching, twisting together to give a spiral bristle material and stabilization by heat shrinkage.

Title: Printing apparatus
Inventor: KASHIWABA TADAO
IPC: B41K3/06
Filed: 1997-08-06
Abstract: The object is to provide a printing apparatus wherein the rotation of endless printing bands is limited in a manner that keeps excessive rotational force from acting on the endless printing bands 7 themselves, thereby avoiding wear, cracking and other damage, and wherein forcible rotation of the endless printing bands causes idle rotation of selector wheels 5 and puts only moderate load on the endless printing bands.      Attention is directed to adoption of selector wheel 5 rotation restricting members of a movable type and to enabling the movable stop members 14 to move when excessive force acts on the selector wheels 5 or the endless printing bands 5. A stop bearing member 15 is provided to abut on elastic sections 14B of the movable stop members 14, and engagement between drive projections 7E and the elastic sections 14B with movement of the endless printing bands 7 enables movement of the movable stop members 14.

Patent CA-2251052-A1 (CA)
Inventor: WUESCHINSKI RUSSEL P
IPC: G05B13/02
Filed: 1997-04-11
Abstract: Chiller operating efficiency is optimized by controlling the system to maintain the condenser liquid refrigerant level at a value which will minimize or prevent gas bypass to the evaporator (110). This is accomplished by sensing the level of liquid refrigerant (170) in the condenser (100) and incorporating fuzzy logic to properly position a multi-position valve (140) which can variably restrict the flow of this liquid into the evaporator (110), according to this sensed parameter (170). The fuzzy logic utilizes as inputs both the level error from a set point level (501) and the rate of change of the sensed level (504). Each of these inputs is combined by fuzzy logic techniques to provide the required output signal to control the opening and closing of the valve.

Title: Polymeric membranes and polymer articles having hydrophilic surface and method for their preparation
Inventor: HESTER JONATHAN F
IPC: B01D67/00
Filed: 1997-08-26
Abstract: Polymeric articles, including membranes, with surfaces having a desired chemical functionality are created by surface segregation of a branched component blended with a compatible, matrix base component, the branched component having the desired chemical functionality. In particular, hydrophilic surfaces are created via surface segregation of a branched hydrophilic copolymer blended into a polymer matrix. The use of branched molecular architecture provides a thermodynamic mechanism for the segregation of the hydrophilic species to the surface and a means for achieving a high surface coverage of the hydrophilic moiety. The branched hydrophilic copolymer can be defined by a random copolymer including two or more methacrylate or acrylate monomers, at least one of which features a short hydrophilic side chain, such as a polyethylene glycol side chain. The branched hydrophilic copolymer is compatible, and well-entangled, with the acrylate polymer matrix.

Title: Method for producing aluminum alloy powder compacts
Inventor: PELLETIER SYLVAIN
IPC: B22F1/142
Filed: 1999-03-08
Abstract: This invention relates to a method for producing sintered parts of aluminum or aluminum alloy with improved mechanical properties using batch degassing, die compaction and liquid phase sintering. The batch degassing consists of holding a prealloyed aluminum powder at a temperature of about 350° to about 450°C in a stainless steel autoclave in which the pressure is reduced to less than 5 x 10-6 torr. Once the desired pressure is reached the powder is cooled down within the autoclave while still under vacuum. The resulting powder is then compacted at a pressure of 20 to 50 tsi at between room temperature and about 250°C, but preferably at a warm temperature of about 65°C. The final densification is completed by liquid phase sintering in argon atmosphere at 625°C. This method allows the production of sintered compacts characterized by a density close to 97% of theoretical, which makes it possible to eliminate the need for a hot working step.

Title: Puncturing of convolutional codes
Inventor: TONG WEN
IPC: H03M13/00
Filed: 1999-07-08
Abstract: In a turbo coder, rate conversion and/or rate matching is achieved by deleting parity bits P1 and P2 from the outputs of two constituent coders, one supplied with data bits to be coded and the other supplied with the same data bits after interleaving. Deleted bits are determined by a rate matching control unit directly for the P1 bits and via a similar position interleaving step for the P2 bits. A similar rate matching arrangement is provided for only two of the three outputs of a rate 1/3 convolutional coder, the third output corresponding to a strongest coding polynomial in terms of minimum free distance and none of its coded data bits being deleted.
