Filed: 1990-04-16
Granted: 1997-11-18
Abstract: A coloring system including a diluent and colorant in particle form. The dilution ratio and particle size can be utilized to control the color of the system during distribution and storage. The colorant can be any desired color, for example, brown, red, etc., and the system can be made such that it is generally invisible when applied to the product. When the food product with the associated coloring system is exposed to heat, e.g. radiation, the colorant becomes visible providing color to the food product in a reselected region. A carrier can also be provided in the coloring system to provide shelf life stability to the coloring system when the coloring system is applied to the food prior to distribution.

Patent CA-2069706-C (CA)
Inventor: CATES ROBERT E
IPC: F28F25/00
Filed: 1992-05-27
Granted: 1996-08-13
Abstract: A cooling system with at least one cooling tower and multiple upper pans or distribution manifold pipes is provided with a strainer tank assembly at the tower lower end in proximity to the sump to receive incoming fluid for cooling, which strainer tank includes a screen to strain particulate material from the inlet fluid communicated to the tower upper end and to equally distribute this fluid at the lowest elevation at a pressure with a higher static pressure component than its dynamic pressure component to avoid a requirement for a flow control valve to provide relatively quiescent fluid for fluid distribution to the tower and fluid transfer media therein.  A pressure relief baffle in the strainer tank is operable in response to a fluid overpressure condition to bypass the screen and open fluid communication to avert catastrophic failures within the fluid circuit.

Granted: 1999-06-22
Abstract: A method and apparatus for controlling data flow between a computer (10) and a group of memory devices (18A-18F) arranged in a particular logical configuration. The system includes a group of first level controllers (12A,12B) and a group of second level controllers (14A, 14B). The first level controllers and the second level controllers work together such that if one of the second level controllers fails, the routing between the first level controllers and the memory devices is switched to a properly functioning second level controller without the need to involve the computer in the rerouting process. The logical configuration of the memory devices remains constant The invention also includes switching circuitry (16) which permits a functioning second level controller to assume control of a group of memory devices formerly primarily controlled by the failed second level controller, In addition, the invention provides error check and correction (Figure 10) as well as mass storage device configuration circuitry.

Patent CA-2084253-C (CA)
Title: Lighting control system with set/reset ground remote
Inventor: ERWIN WILLIAMS RANDALL
IPC: H05B37/02
Filed: 1992-12-01
Granted: 1997-02-18
Abstract: A lighting load can be turned on/off manually from one or more remote switching stations as well as from a master switch controller station, with ON/OFF control  signals  produced  at  the  remote  switching stations being transmitted to the master controller circuit on the traveler conductor of a conventional single phase AC power distribution system.   The main controller has an internal dual mode DC power supply which is referenced to load potential.  The dual mode power supply derives operating power from the voltage across  the  gate  controlled  power  switch  which corresponds with essentially hot potential when the power switch is off.  The voltage drop across the power switch is boosted by a step-up transformer when the power switch is on.  Remote turn-on and turn-off signals are derived independently from the hot power conductor and ground safety power conductor, respectively.  Remote turn-on and turn-off of the master power switch is accomplished without interfering with automatic turn-off operation of the controller.

Title: Enclosure for painting and a method of enforcing evaporation from a coating on a panel surface
Inventor: JEFFS CHRISTOPHER S
IPC: B05D3/02
Filed: 1993-03-10
Granted: 1999-04-20
Abstract: A coating of paint on a panel is dried by directing a narrow jet of air from a supply, preferably from an air mover,  held at a predetermined distance from the panel towards  one edge  region  of  the  panel,  the  jet  being substantially narrower,  when it reaches  the panel  edge region,  than the length of the panel edge and the jet being inclined to the plane of the panel such that the air from the jet is entrained by the panel in a spreading laminar  flow across  the panel  surface  from  that  edge region to all the other edges thereof.  This induces such laminar  flow over  substantially the whole  surface  and replaces vapor-laden air closely adjacent the surface with fresh air to accelerate drying.   In a painting booth for cars several such air movers use part of the bulk air flow in the booth.

Abstract: A compact representation of a tree data structure and techniques for navigating the compact representation. The compact representation is a list. Each element of the list represents a node of the tree and the list is organized according to a preorder traversal of the tree. Each list element contains only the index of a data dictionary entry for the kind of item represented by the node corresponding to the list element. The navigation techniques permit the location of the list element for the sibling of the node corresponding to the given list element, the location of the list element for that node's parent, and in the case of a parent node, the location of the list element for any child of the parent.  The navigation techniques work by finding the listelements for subtrees. The subtrees are found by techniques based on the fact that the number of children of all of the nodes in a subtree minus the number of nodes in the subtree always equals -1. The number of children of a given node is determined by a valence function which takes the index of the data dictionary entry as iitsargument.

Abstract: Two major concerns associated with abrasive articles, particularly in fine grade articles, are loading and product consisten-cy. Loading is a problem caused by the filling of the spaces between abrasive grains with swarf, and the subsequent build-up of that material. If the abrasive article is made via a conventional process. the adhesive or binder system can flow before or during curing, thereby adversely affecting product consistency. This invention provides a coated abrasive article. The abrasive compo-sites have a predetermined shape, e.g., pyramidal. The dimensions of a given shape can be made substantially uniform. Further-more, the composites are disposed in a predetermined array. The coated abrasive article can be prepared by a method comprising the steps of: (1) introducing a slurry containing a mixture of a binder and a plurality of abrasive grains onto a production tool; (2) introducing a backing to the outer surface of the production tool such that the slurry wets one major surface of the backing to form an intermediate article; (3) at least partially curing or gelling the binder before the intermediate article departs from the ou-ter surface of the production tool to form a coated abrasive article; and (4) removing said coated abrasive article from the produc-tion tool.
