Patent CA-2100738-C (CA)
Inventor: TREFZ HARLIN J
IPC: F16H7/08
Filed: 1993-07-16
Granted: 1999-02-09
Abstract: A belt clutch control apparatus is disclosed having a control handle and linkage means for selectively controlling the transmission and power from a driving pulley to a driven pulley through a driving belt. In a preferred embodiment, the apparatus is specially adapted to control the operation of the cutting blades on a riding mower. The linkage includes an undercenter connecting link for transmitting rotational movement of the control shaft to a bellcrank, which engages a tension spring to operatively move an idler pulley between engaged and disengaged positions relative to the driving belt. The undercenter link moves exclusively between first and second undercenter positions, and is never forced into an overcenter position. An assist spring is provided for securing the undercenter link in both its on an doff undercenter positions, thereby relieving the idler pulley spring for this purpose. The linkage significantly reduces both the travel and effort required to move the control handle between its on and off positions.

Abstract: A channel for lapped siding includes an elongated nailing strip and an abutment strip with an upper cover strip. This provides a generally C-shaped cross-section. Inside the channel is a rectangular tab that extends at an angle away from the nailing strip up to the cover strip.      The channel is nailed to a building. Lapped siding is also nailed to the building with edges of the siding positioned in the channel. The edge of the siding is slit horizontally to allow the tab to intersect the edge of the siding. Any water that gets into the channel will run along this tab away from the building wall to an exterior surface of the siding. This keeps the water from flowing behind the siding.

Title: Data analysis apparatus and methods
Inventor: BORGIDA ALEXANDER TIBERIU
IPC: G06F17/30

Granted: 2000-03-14
Abstract: An information retrieval system implemented as a virtual data base management system which uses a knowledge base management system to provide a problem-oriented conceptual schema for one or more standard data base management systems. In the conceptual schema, a hierarchy of concepts is used to organize individual objects. A classifier determines which concepts an individual object is a representative of and determines the relationship of new concepts to existing concepts. The use of a knowledge base with a classifier permits conversion of queries into concepts and detection of changes in the relationships between individual objects and the concepts. A window-based user interface permits flexible and experimental access to the information. Special features of the user interface permit the user to specify conversion of a query into a concept, to establish monitors to detect such changes, and to define a query by specifying a portion of a graph.

Title: Thermoplastic polyurethane elastomer, process for producing same, apparatus for producing same and elastomer fibers made from same
Inventor: OGAWA YASUHIRO
IPC: D01F6/70
Filed: 1992-04-08
Granted: 2000-10-10
Abstract: A thermoplastic polyurethane elastomer containing a very small amount of small grains, and having a high molecular weight and a narrow molecular-weight distribution. Such high-quality thermoplastic polyurethane is excellent in melt moldability and allows to prevent yarn breakage in producing fibers by melt spinning, for example. Such polyurethane elastomer can be produced by melt-polymerizing a prepolymer and a low-molecular diol at a relatively high temperature in a short period of time. This invention also provides an apparatus for producing the polyurethane elastomer, and fibers formed of said elastomer.

Abstract: A filter tow from cellulose acetate filaments and/or staple fibers is described on the surface of which an additive from cellulose chain-splitting enzymes is present, at least the surface of the filaments and staple fibers consisting of a cellulose acetate having an acetyl number of less than 53%, preferably less than 49%.  The method for the production of such a filter tow comprises spinning cellulose acetate filaments from a solution in acetone, of cellulose acetate of an acetyl number of at least 53% if necessary, cutting the filaments to staple fibers, gathering the filaments and/or staple fibers to a filter tow and applying an additive, the filaments and staple fibers being hydrolyzed and as additive one of cellulose chain-splitting enzymes is used.  There are described also a tobacco smoke filter element from such a filter tow and a method for its production.  The filter tow and the tobacco smoke filter element show improved biodegradation under the action of environmental influences, but without danger of degradation when they are stored under the conditions customarily used today.

Abstract: A modular endless track assembly which bolts to the wheel of a wheeled vehicle (e. g. pickup truck or ATV). The assembly includes a wheel retainer plate, drive drum, track frame and plurality of idler wheels, track tension adjuster, and vehicle support bracket. The drive drum and idler wheels cooperate with lugs and channels at the track. The support bracket includes an anti-torque coupler mounted between the vehicle and track frame.      The coupler centers the track to an equilibrium position and prevents over rotation. The mounting position of the coupler and mounting brackets is varied at the track frame to accommodate front and rear wheel track assemblies. A recurring, W-shaped groove pattern at the track cooperates with the idler wheels to self-clean the track and maintain controlled vehicle steering.

Abstract: A gate valve assembly for controlling fluid flow is provided with wireline-cutting inserts loose-fitted in either of, or both of, the gate opening and at least one of the seats. Each insert has a length that prohibits it from extending beyond the opening in which it is received so that the contact surface between the gate and an adjacent seat forms a continuous seal and the inserts serve only a wireline-cutting function, thus eliminating the possibility of sealing surfaces being damaged by wireline-cutting.

Abstract: Lighting fixtures which feature indicia illuminated more uniformally and with greater brightness than in conventional lighting fixtures.  LEDs which operate at a higher frequency/shorter wavelength, such as blue LEDs, emit light which causes the transformation material to reemit, reradiate or emit light at a lower frequency/longer wavelength with increased brightness and uniformity.
