Patent CA-2061519-A1 (CA)
Inventor: ASAKAWA NAOKI
IPC: C07K17/14
Filed: 1992-02-19
Abstract: This invention relates to a packing for chromatography whereby a low molecular weight substance contained in biological samples can be analyzed directly with a high-level of accuracy without any pretreatment. In the packing of the present invention a protein such as avidin or ovomucoid is bound to the support via a straight or branched spacer optionally having a functional group such as a cyano group. Given that enantiomers interact differentially with proteins, a substance can thereby be separated into its optical isomers. Furthermore, a purification column packed with said packing is disclosed.     According to the present invention, a low molecular weight substance can be directly and accurately analyzed without requiring any pretreatment for the purpose of removing biological macromolecules. When the packing of the present invention is employed in the purification column, the time required for the pretreatment can be shortened.

Title: Method of producing products from rubber compositions
Inventor: KUC JOHN SR
IPC: B29B7/00
Filed: 1992-03-16
Abstract: This invention directs itself to a process for producing thermoplastic resin products where granulated or particulate vulcanized rubber is sprayed by a heated heavy paraffin distillate composition to form a first intermediate mixture composition. The first intermediate mixture composition is passed through a heating chamber (22) on a conveyor (20) and combined with particulate thermoplastic scrap material in an approximating weight percentage of 30% thermoplastic material to 70% first intermediate mixture material. The combination forms a second intermediate mixture composition which is masticated in a masticator (30) and extruded through a single screw feed mechanism (32) for palletizing and producing thermoplastic resin products which are useful for molding.

Title: Process and composition for cladding optic fibers
Inventor: MINNS RICHARD A
IPC: C08F20/26
Filed: 1992-05-05
Abstract: CLADDING OPTICAL FIBERS Abstract of the Disclosure In a process for cladding an optical fiber, a photoinitiator monomer having both a photoinitiating group and an ethylenically unsaturated group is reacted with a fluorosubstituted monomer having an ethylenically unsaturated group, thereby preparing a copolymer having pendant photoinitiating groups. This copolymer is then mixed with a fluorosubstituted diacrylate, thereby forming a photopolymerizable composition, which is coated on to the optical fiber and exposed to ultraviolet light, thereby curing the photopolymerizable composition to produce a cladding on the optical fiber. Preferred claddings can have refractive indices below 1.35.

Abstract: A pneumatic tire is provided herein comprising a tread portion having a pair of tread edges. The tread portion is provided with at least two main circumferential grooves and with axial grooves to define tread blocks which are arranged in two or more circumferential rows. The tread blocks comprise shoulder blocks which are between each axially-outermost main circumferential groove and each tread edge.

The axial width of the axially-outer shoulder block part, measured from the tread edge to the narrow circumferential shoulder groove is 0.06 to 0.25 times the tread half-width between one tread edge to a tire equator.      The mean groove depth of the narrow circumferential shoulder groove is 0.3 to 1.10 times the groove depth of the main circumferential grooves. Each of the tread blocks in the two or more circumferential rows is provided with one or more sipes extending circumferentially of the tire to divide the tread block into two or more axial parts. The sipe or sipes have a width of 0.2 to 1.5 mm. The sipe or sipes are disposed in the axially-outer shoulder block part. The mean depth of each of the sipe or spies is 0.25 to 1.25 times the mean groove depth of the narrow circumferential shoulder groove.

Title: Isolated drive sprocket assembly
Inventor: DIEKEVERS MARK S
IPC: B62D55/135
Filed: 1991-06-03
Abstract: A drive sprocket assembly (16) for driving an endless track chain assembly (22) for propelling a vehicle (10) includes a support hub (24), which is mountable to the power drive system (14) of the vehicle (10), and a plurality of replaceable sprocket segments (26) which are secured to the support hub (24). Each sprocket segment (26) includes replaceable teeth (40) which are resiliently isolated from the other components of the sprocket segment (26) by a plurality of non-metallic resilient discs (42), thus reducing noise generated by the sprocket teeth (40) striking the endless chain assembly (22). Conventional drive sprocket assemblies use a one-piece toothed sprocket, or tooth segments having several teeth, bolted directly to a support member. These prior sprocket assemblies generate considerable noise and vibration from impacting of the teeth with an endless chain. The subject sprocket assembly (16) produces low levels of noise by utilizing individual replaceable teeth (40), or teeth segments (62), which are isolated from the other components of the sprocket segments (26) by resilient discs (42).

IPC: B29C49/00
Filed: 1992-10-08
Abstract: Personal leather goods (PLG's) such as wallets, billfolds, pocket calendars have a portion which is required to bend repea-iedly. This bending causes cracking and extreme wear which adversely affects the look of the item and reduces its useful life. Dis-closed is a mechanical hinge which attaches to leather-like panels of such PLG's. The hinge (20) includes a set of interleaving knuckles (32) of relatively soft material which form an axial bore (34) along the length of the hinge, the bore receiving a thin pin-tle (80) made of a relatively stiff but resilient material. The pintle (80) is shorter than the axial length of the bore (34) and is held into the bore by end caps (90), either separately applied or integrally formed with the hinge leaf (30). The leaves (30) of the hinge (20) have an overall curving shape having a concave side and convex side to permit the panels (12) to which the hinge (20) is att-ached to remain parallel when materials are received between them. Alternative constructions are shown, including a third panel comprising a paper binder-like spine (45) or a body (48) made of a series of independently attached knuckles (32) and tubular body portions (40a) which in turn form a second, expandable hinge-like body.

Abstract: An optical filtering device incorporates first and second prisms, the latter prism counteracting the angular dispersion of the former prism. A spatial light modulator provides a positionally variable optical stop located to block radiation within a wavelength interval and received from a location within a scene. Unobscured radiation from that and other scene locations passes to a camera, which produces an image on a display.      Opaque pixels in the stop are positioned to block unwanted light sources.      The invention attenuates potentially dazzling monochromatic radiation while retaining radiation at other wavelengths for imaging purposes.

IPC: H03K17/62
Filed: 1993-10-19
Abstract: A multiplexer, preferably on an integrated circuit chip, receives a plurality of buses each having a plurality of lines responsive to binary indications and passes the binary indications in the lines of a particular one of the buses.          The multiplexer includes a plurality of circuit blocks each responsive to the binary indications in the lines of an individual one of the buses.  Each block has a plurality of recursive circuits each having first and second stages.  The second stages of the recursive circuits in an individual one of the circuit blocks receive an individual one of a plurality of control indications at a first side of the block to activate the first stages in such recursive circuits.  The first stage in each recursive circuit in each individual circuit block receives at a second side of the block the binary indications in an individual line in an individual one of the buses to obtain a signal from such first stage in accordance with such binary indication upon the activation of such first stage.  The output lines of the same binary significance in the different circuit blocks are connected in an OR relationship.  Each output circuit in a plurality is responsive to the signals in the OR relationship of an individual binary significance from the recursive circuit in the activated block to provide output signals from the multiplexer.  The multiplexer accordingly provides a recursive and expansible arrangement for passing signals at each instant from a selected bus without any wire crossovers.
