Title: Binding agent dispersible in hot water, based on fat-coated farinaceous particles
Inventor: THOMAS REMI
IPC: A23P1/02
Filed: 1995-07-17
Abstract: A process for producing a roux-like binding agent for foodstuffs. Fine particles of farinaceous material are transported into an enclosed particle coating zone where a molten, high-melting point fat is sprayed, in the form of fine droplets, onto the particles to coat them. At the same time, the coated particles are cooled to a temperature below the melting point of the fat using chilled gas. The coated particles are flowable and disperse readily in hot water.

Title: Mouse adapted to scan biometric data
Inventor: BORZA STEPHEN J
IPC: G06K9/00
Filed: 1997-02-12
Abstract: In the past, contact imaging devices were large and costly. It has been proposed that for contact imaging device adoption for the personal computing market, cost and size must be reduced. In an attempt to address these concerns, a biometric pointing device such as a mouse is presented incorporating therein a contact imager. The contact imager fits within a small enclosure. Further, data transmission means within the mouse provides a signal to a single port on a computer indicative of the output data from both the contact imaging means and the pointing device.

Abstract: A method of treating polyolefin comprises (i) a ligand-decomposition step of contacting polyolefin, which is obtained by the use of a transition metal compound containing ligands having cyclopentadienyl skeleton, with a ligand decomposer, such as water, oxygen, alcohol, alkylene oxide or peroxide, to decompose the ligands contained in the polyolefin, and (ii) a ligand-removal step of heating the polyolefin contacted with the ligand decomposer to remove the decomposed ligands from the polyolefin.          According to this method, the residual ligands having cyclopentadienyl skeleton, which are contained in the polyolefin produced by the use of a transition metal compound containing ligands having cyclopentadienyl skeleton, are decomposed and removed from the polyolefin, whereby polyolefin diminished in odor development in the molding process can be obtained.

Patent CA-2210943-A1 (CA)
Inventor: O'LEARY RAYMOND P
IPC: H02J3/38
Filed: 1997-07-21
Abstract: A control arrangement and method is provided for high-speed source-transfer switching systems (HSSTSS). The HSSTSS supplies an electrical load with alternating current from either a first source or a second source via respective first and second solid-state switches. The HSSTSS also includes a controller that samples the voltage waveforms of each of the first and second sources to detect when transfer between the sources is desirable, e.g. outages or voltage that is either too low or too high. The controller provides appropriate control signals to control operation of the solid-state switches and transfer supply of the load therebetween.   The control arrangement avoids undesirable current flow between sources via a comparison of the voltages of the sources and current in the outgoing source, i.e. a polarity comparison to ensure that the current that will flow in the incoming source after transfer will be in opposition to the current flowing in the outgoing source before transfer. Thus, the transfer is delayed until the polarity comparison is satisfied. Either separately or in combination with the polarity comparison, the control arrangement minimizes undesirable transfer delays by establishing a forced commutation condition before issuing control signals to perform the transfer between sources, i.e. the transfer is delayed until after a forced commutation condition of the current in the outgoing source is established. The forced commutation condition is preferably established by the incoming source voltage differential and the outgoing current being of the same polarity such that the voltage differential across the solid-state switch that is being turned on will establish an initial change in current flow in opposition to the current flow in the solid-state switch to be turned off.

A water dispensing system is coupled to the apparatus to controllably dispense a quantity of water for mixing with a quantity of powder dispensed from the hopper. A mixing assembly communicates with the hopper and with the water dispensing system to combine powder and water. The mixing assembly includes a frothing mechanism extending into a whipping chamber which communicates with a mixing chamber to mechanically agitate the powder and water combined in the mixing chamber. A weir is positioned in a dispensing tube to minimize the face surface of the angle of repose of the powder in the tube. A vapor removal assembly is positioned between the mixing chamber and the hopper to remove moist air from the mixing assembly to reduce intrusion of such moist air into the hopper and absorption by the beverage powder. A vent tube is provided in the heated water dispensing system to promote draining of a dispensing line communicating with the mixing chamber and to prevent the accumulation of gas bubbles in the dispensing line. A by-pass water system is provided in the apparatus which communicates with a water dispensing line to controllablyintroduce unheated water into the water dispensing system. Additionally, an illuminated display is provided on a front portion of the apparatus. A dispensing nozzle is attached to the mixing assembly for directing the dispensing of a beverage into a container.

Title: Local area network cabling arrangement
Inventor: FRIESEN HAROLD WAYNE
IPC: H01B11/02
Filed: 1998-01-29
Abstract: A cabling media which is suitable for data transmission with relatively low crosstalk includes a plurality of metallic conductors-pairs, each pair including two plastic insulated metallic conductors which are twisted together. The characterization of the twisting is important and relates to parameters such as twist length as well as core strand length/lay. More specifically, particular combinations of twist lengths and core strand length/lay are purposely selected for each insulated pair of the cable in order to achieve performance capabilities that significantly surpass those required under TIA/EIA-568A. In one particular embodiment of this invention, a cable comprises as its transmission media, four twisted pair of individually insulatedconductors with each of the insulated conductors including a metallic conductor and an insulation cover which encloses the metallic conductor. The twisting together of the conductors of each pair is characterized as specifically set out herein and the plurality of transmission media are enclosed in a sheath system which in a most simplistic embodiment may be a single jacket made of a plastic material. As a result of the particular twist scheme employed for the conductor pairs, operational performance of the resulting cable is improved. Also, the cable of this invention is relatively easy to connect and is relatively easy to manufacture and install.
