Title: Method and apparatus of machining with improved chip control
Inventor: YANKOFF GERALD K
IPC: B05B17/06
Filed: 1991-08-27
Abstract: A nozzle apparatus (10) adapted for use with machine tools of different configuration, which perform different machining operations, comprises a nozzle body (26) having a nozzle insert (42) mounted within an outlet passageway (36) formed in the nozzle body at its intersection with a coaxial, larger diameter inlet passageway (28) connected to a source (34) of coolant.

Title: Molded case circuit breaker low friction latch assembly
Inventor: PANNENBORG ERICH J
IPC: H01H71/12
Filed: 1993-06-03
Abstract: MOLDED CASE CIRCUIT BREAKER LOW FRICTION LATCH ASSEMBLY         ABSTRACT OF THE DISCLOSURE A circuit breaker latch assembly eliminates the need for polishing the opposing latch surfaces to reduce static surface friction and lower the latching force.  The end of the circuit breaker cradle operator is offset relative to the restraining surface of the armature-latch to reduce the static friction that must be overcome to move the armature-latch away from the cradle operator.  Subsequent release of the cradle operator then allows the circuit breaker operating mechanism to separate the circuit breaker contacts upon the occurrence of predetermined overload current conditions.

Patent CA-2101301-A1 (CA)
Inventor: KLEIN ERNST G
IPC: F27D19/00
Filed: 1993-07-26
Abstract: A system for cooling a single or plural zones of the exterior of a furnace or similar hot device, e.g., kiln, calciner, etc.   Each zone is cooled by a respective cooling assembly.   The operation of the assemblies is effected by a common control system.   Each cooling assembly comprises a shroud,  an induction cooler, e.g.,  an exhaust fan,  and at least one atomizing spray nozzle.  The shroud is in the form of a jacket disposed over the associated exterior zone of the furnace and is spaced therefrom to form a cooling chamber therebetween.   The exhaust fan is coupled to the shroud for inducing the flow of cooling air through the cooling chamber so  that  it  absorbs  heat  from  furnace's  exterior.    The atomizing spray nozzle is also coupled to the shroud and to a water and an air supply for introducing atomized droplets of water into the chamber, whereupon the droplets vaporize to absorb heat from the furnace's exterior.  The exhaust fan vents the air and steam from the shroud means.  A controller controls the operation of each cooling assembly pursuant to feed-back signals from respective thermal sensors mounted in each cooling assembly.

Title: Esophageal-stomach displacement electrode
Inventor: ANDERSON JOHN
IPC: A61B5/296
Filed: 1992-02-10
Abstract: An esophageal-stomach displacement electrode comprises a flexible tubular member (10) designed to be inserted through the esophagus (E) into the stomach (S). An electrode (14) is carried by the tube (10) in the region of its distal end (12).

Title: Sludge treating process and apparatus
Inventor: BARR DEREK J
IPC: C02F11/13
Filed: 1993-09-23
Abstract: ABSTRACT            In a continuous process for drying a sludge composed of combustible material and water, the wet sludge is first mixed with a proportion of material which has been dried in the process and is then fed into a hot gas stream from a burner.  The hot gas stream carries the mixture along and dries it, and a proportion is tapped off and mixed with the incoming wet sludge.  A part of the remainder is fed, with supplementary fuel if necessary to the burner to create the hot gas stream.  The rate of fuel supply is varied in dependence on a temperature of the hot gas stream when it exhausts from the mixture drying operation.

Patent CA-2109942-A1 (CA)
Inventor: KOTLARIK JOHN J
IPC: G06T1/00
Filed: 1992-06-12
Abstract: A method for agglutination detection using optical imaging of reaction wells containing agglutination objects in a programmable random access automated apparatus for perforing agglutination assays is provided. An image of the agglutination objects in the reaction wells is taken with analyzation of the intensity values and transitions through relative portions of the image and background which provides intensity values suitable for classifying. The method utilizes slope information from a derivative (Fig. 34 A-E, second row) rather than absolute intensities, thus allowing scoring algorithm based on slope total information. The agglutination detection method uses a CCD camera to take an image at each well (Fig. 34 A-E, first row) of a multiple well cartridge, thus providing information suitable for analyzing from the image detection apparatus, the apparatus processes the information to generate a visual indication of the results of the assays being performed. A  micro-processor is provided to assist in the operation of the apparatus as well as the image processing data collection and analysis.
Patent CA-2109966-A1 (CA)
Title: Can crusher
Inventor: BELONGIA DAVID C
IPC: B30B9/32
Filed: 1993-11-25
Abstract: ABSTRACT OF THE DISCLOSURE A can crusher is provided with a can feed hopper having an open inlet at the top of the can crusher through which opening a plurality of cans may be inserted one after another to fill the hopper.  Sequentially, each can falls by gravity into a crushing compartment where a power-driven ram crushes the can axially to crumple the can's cylindrical wall thereby reducing the can's length to about one-fourth or less of its original length.  The crushed can falls by gravity through a discharge chute to be automatically discharged.  Each can in the hopper automatically falls in succession into the crushing compartment to be crushed and discharged.  To prevent human fingers from being inserted through the hopper inlet or the discharge chute and into the crushing compartment, the guiding chute paths are non-linear and/or tortuous to reduce the length thereof and to block a straight finger insertion into the crushing compartment.  To remove an uncrushed can from the crushing compartment, the can feed hopper may be detached; and this detachment operation automatically operates an electrical switch to disable a power drive for the ram to thereby prevent crushing of the human fingers removing the uncrushed can.  The preferred can crusher can be mounted on a vertical wall or it can be seated on a counter or table support.  The cans are fed into the top of the can crusher, and travel in A straight vertical fall through the can feed hopper, the crushing compartment and the discharge chute to discharge at a lower portion of a front wall of the can crusher housing.
