The sodium bicarbonate ranges from about 35% to about 55% and preferably from 40% to about 44% by weight of the total weight. It includes a quantity of anionic detergent comprising at least about 18% by weight of the total weight of said composition, admixed into said compressed wafer prior to formation of said wafer in an amount sufficient to form a detergent solution in water. Preferably, the surfactant comprises about 6% to 10% of sodium lauryl sulfate, about 12% to 18% of alkyl aryl sulfonate, and about 4% to 6% of tetra sodium ethylene diamine tetra acetic acid. Also included is a quantity of mold release to permit easy release of the wafer after compression. The mold release comprises about 3% to 7% of silica by weight of the total weight of the formulation. The wafer is packaged in an outer package sealingly protecting the wafer from air and moisture until the package is opened for use.

Title: Cable management system with automatic mapping
Inventor: WISE JAMES H
IPC: H04N7/24
Filed: 1994-06-24
Abstract: ABSTRACT    A cable management system which provides routing of wired services between service lines (16) and user lines (18). Each service line enters the cable system at a service termination unit circuit card (22) which also holds a portion of a crosspoint switch matrix (126).          Each user line enters the system at a line termination unit circuit card (20).  The service termination unit circuit cards are all mounted to connectors (36) on a first side of a centerplane board (24) and the line termination unit circuit cards are mounted to connectors (36) on the other side of the centerplane board. Pins (37) extending through the centerplane board interconnect the connectors so that any service line can be connected to any user line.  A system controller card (26) mounted to the centerplane board communicates with the circuit cards via a bus (38) on the centerplane board.  Each of the service and line termination unit circuit cards is provided with a unique identification code corresponding to the connector in which it is installed, in addition to "as built" information characterizing the card.  The controller card polls all the service and line termination unit circuit cards to generate a "map" of all the "assets" of the system.          Further, each line termination unit circuit card provides a predetermined voltage to all of the service termination unit circuit cards.  The service termination unit circuit cards respond to the absence of that predetermined voltage from a connector on the second side of the centerplane board by opening all connections to that connector.

Title: Speech Recognition Using Bio-Signals
Inventor: DESIMONE JOSEPH
IPC: G10L21/02
Filed: 1994-12-12
Abstract: The recognition rate of a speech recognition system is improved by compensating for changes in the user's speech that result from factors such as emotion, anxiety or fatigue. A speech signal derived from a user's utterance, and a bio-signal, which is indicative of the user's emotional state, are provided to a speech recognition system. The bio-signal is used to provide a reference frequency that changes when the user'semotional state changes. An utterance is identified by examining the relative magnitudes of its frequency components and the position of the frequency components relative to the reference frequency.
Patent CA-2138220-A1 (CA)
Inventor: HOSHIZAKI T BLAINE
IPC: A63C17/22
Filed: 1994-12-15
Abstract: An improved fastening system for the axles of wheels of in-line roller skates is disclosed.  This tri-axle system includes a multi-position spacer which is mounted in a spacer aperture in the skate chassis, which spacer has an axle aperture to receive the wheel axle.  Both the spacer and the spacer aperture are generally triangular in shape. The axle aperture is offset from the geometric centre of the spacer so as the spacer is rotated in the spacer aperture both the vertical and horizontal position of the axle may be altered with respect to the chassis.  This allows a user to adjust both the wheelbase of the skate and the rocker easily and quickly.
Patent CA-2144285-A1 (CA)
Inventor: KOMOROWSKI KARL J
IPC: A47C3/20
Filed: 1995-03-09
Abstract: The chair of the present invention includes a power-assisted linear actuation drive mechanism having a lead screw nut which is linearly movable upon rotation of a power screw for selectively actuating the lift and tilt linkage mechanism for causing forward lifting and tilting movement of the chair when the motor is operated in a first direction. Rotation of the screw shaft in a second opposite direction acts to lower the chair to the normal seating position. Continued rotation in the second direction causes a first cam block pivotably mounted to the lead screw nut to engage a first follower assembly for causing extension of the leg rest assembly. Further rotation in the second direction causes a second cam block pivotably mounted to the lead screw nut to engage a second follower assembly for causing reclining movement of the chair. This sequential operation of the leg rest assembly and the reclining linkage are independent and may be easily disabled to selectively eliminate either of the features.

Title: Process for Producing Thermoplastic Products Having Oriented Components
Inventor: SUWANDA DEDO
IPC: B29C48/30
Filed: 1993-11-09
Abstract: There is disclosed a process for the continuous production of a thermoplastic product having oriented components. The thermoplastic compound may include filler. Preferably the filler material is characterized by high aspect ratios (length to diameter). The filler may be an inorganic filler such as mica and talc flakes, glass and carbon short fibers or organic cellulosic materials derived from wood/forest by-products and agricultural by-products. Plastics such as polyolefins, vinyls, styrenics, polyesters and polycarbonates may be used. The process may be used to manufacture both integral foam products and substantially solid products of various shapes which may have flexural/bending strength and modulus 2-10 times higher than conventionally produced products made of the same plastic/polymer material (foamed and unfoamed). The product produced by the process may have filler concentrations as high as 75 percent. The product is made by an extrusion process which orients the thermoplastic polymer and the filler, when present, in the longitudinal direction during extrusion, and which prevents relaxation of the thermoplastic polymer thereby substantially preserving the imparted orientation. With respect to the integral foamed core embodiment, the die assembly is designed to facilitate orientation of polymer molecules and filler particles, when present, in order to produce an oriented skin; to form a cavity in the thermoplastic compound; to foam thermoplastic compound into the cavity due to the action of a foaming agent; and to cool the thermoplastic compound to form an integrally foamed product.

Title: Force multiplier
Inventor: CROWDER KENNETH L
IPC: B63B22/12
Filed: 1994-08-15
Abstract: The present invention utilizes low-friction, stepped triggering of successively higher-pre-loaded, counterdirected, nested stages (FX1, FX2) in a compact configuration to efficiently multiply an input force (F1). The present invention thus presents a novel force-multiplying mechanism (500-504) for incorporation in any apparatus taking advantage of its ability to convert a force of a given magnitude into a force of greater magnitude. Such devices include, but are not limited to, those utilizing hydrostatic pressure for actuation of flotation, marking and retrieval devices, those actuated by barostatic, mechanical, and pneumatic pressure, and those which trigger chemical (including pyrotechnic), electrical, mechanical, and pneumatic devices. There is theoretically no limit to the force multiplication inherent in the design, given the option of successive stages and ever-increasing driving forces.

Title: Double-delta turnstile antenna
Inventor: PODGER JAMES STANLEY
IPC: H01Q1/36
Filed: 1996-03-04
Abstract: This antenna has two sets of conductors. Each set is two coplanar triangles with a corner from each triangle at the centre and with the two triangle sides opposite those corners being positioned parallel to each other. The planes of the two sets are perpendicular to each other, with the junction of the two planes being close to the lines through the centres of the parallel sides and the centers of the sets. If the two structures were positioned so that the junction of the two planes was vertical and if they were fed so that the currents in corresponding parts were equal in amplitude and different in phase by 90 degrees, a horizontally polarized omnidirectional radiation pattern would be obtained. Such an omnidirectional antenna would have more gain than a turnstile array of half-wave dipoles with less wind resistance than a Masters super turnstile antenna.
