Title: Stamp Formed Connector for Achieving Equal Length Exhaust Pipes
Inventor: CLEGG MICHAEL W
IPC: F01N13/08
Filed: 1994-03-10
Abstract: An  exhaust  system  is  provided with  a  stamp  formed connector for joining a pair of upstream exhaust pipes to at least one downstream exhaust pipe.   The connector includes a pair of plates that are formed to define opposed channels.  The plates are secured in face-to-face relationship such that the channels define exhaust passages extending between the plates.  The passages are curved to achieve the most desireable routing of exhaust pipes.          Additionally, the exhaust pipes may be bent in close proximity to the connector to achieve most efficient routing of pipes on the vehicle.  The bending of the pipes and the curved configurations of the passages in the muffler are intended to substantially equalize travel lengths for exhaust gases between upstream ends of the exhaust system and the muffler.

Patent CA-2124648-A1 (CA)
Inventor: SIMMONS MICHAEL L
IPC: H02G3/08
Filed: 1994-05-30
Abstract: There is no prior way to retrofit one or more laterally extending electrical boxes for extra switches, outlets or accessories such as rheostatic controls in existing walls without tearing out a portion of the wall, removing the box, rewiring a new ganged box and refinishing the wall. This invention provides modular lateral box extensions constructed to be installed from the open front end and supported by the installed box anchored to a beam with the wall being cut only enough to receive the extension modular box. This efficiently requires the wiring of only additional modules and avoids repair and repainting of walls.

Patent CA-2134182-A1 (CA)
Inventor: CHEN LONG J
IPC: B65G53/42
Filed: 1994-10-24
Abstract: A nozzle for fluidizing particulate material, such as mine tailings, comprising a body having a rear inlet end and a cylindrical surface adjacent a front end, the body having a passageway leading from the rear end to an outlet orifice located in the cylindrical surface, with the passageway including an outlet portion diverging at an acute angle from a central axis of the cylindrical surface. The nozzle also has a resilient sleeve surrounding the cylindrical surface and which is capable of sealing the orifice when pressure in the passageway is low relative to pressure in the slurry outside the nozzle. The sleeve is expandable to allow fluid under pressure to exit the nozzle in a generally forward direction when fluid such as water is supplied to the rear end of the nozzle. The invention also includes a self-closing mounting fixture located in the wall of a vessel such as a silo, which prevents escape of slurry from the silo when the nozzle is removed from the fixture for servicing or exchange.
Patent CA-2135300-A1 (CA)
Inventor: MILLS DAVID E
IPC: C08L67/02
Filed: 1993-05-07
Abstract: This invention relates to a copolyester/polyamide blend having an improved flavor retaining property and clarity. More particularly, the present invention relates to an essentially noncrystalline copolyester containing poly(ethylene terephthalate) un-its blended with a critical amount of a nonhydroxyfunctional polyamide. The use of a nonhydroxyfunctional polyamide in a criti-cal amount reduces the concentration of acetaldehyde contained in the poly(ethylene terephthalate) copolyester, and thus, im-proves the storage property, flavor-retaining property, and fragrance retaining property of a food or the like.

Title: Method and apparatus for controlling an actuatable restraining device in response to discrete control zones
Inventor: MAZUR JOSEPH F
IPC: B60R22/20
Filed: 1994-12-01
Abstract: An apparatus for controlling an occupant restraint system, such as an air bag (102), includes position sensors (80, 84, 86) for sensing position of an occupant and a weight sensor (70) for sensing weight of the occupant.          Both the position sensors (80, 84, 86) and the weight sensor (70) are connected to a controller (24).  A seat position sensor (30), a seat back incline sensor (36), and a belt payout sensor (64) are also used to determine occupant weight and position.  A vent valve (120) is connected to the reaction can (103) of the air bag (102) and is controlled by the controller (24).  The controller (24) establishes an occupant weight range from the weight sensors and an occupant position range from the position sensors.  The controller (24) selects one of a plurality of discrete control zones dependant upon both the sensed occupant position range and the sensed occupant weight range.  The controller (24) then provides a regulating signal to the vent valve (120) based on the selected one of the discrete control zones.

Title: Improved electrophysiological mapping and ablation catheter and method
Inventor: LIPSON DAVID
IPC: A61B5/296
Filed: 1995-01-25
Abstract: A mapping and ablating catheter having a short distal tip electrode comprising a bio-compatible outer surface and a thermal dissipating mass for dissipating heat received by the electrode. The outer surface may be formed by plating a thin layer of gold or platinum on the dissipating mass, or the entire electrode may be formed of a homogenous material such as a gold alloy that is bio-compatible thereby forming the outer surface with the mass itself.   An alloy having a thermal conductivity greater than pure platinum is used so that the ablation procedure can be completed before exceeding the temperature limits. In one case, the entire electrode was formed of a 88% gold 12% nickel alloy. The electrical feed to the electrode is oversized to also dissipate heat received by the electrode. The electrode is no greater than five mm in length yet produces an ablation volume equal to or greater than longer electrodes.      One or more band electrodes may also include thermal dissipating masses.

Patent CA-2143766-A1 (CA)
Title: Circuit tracer
Inventor: SATTERWHITE JAMES R
IPC: G01V3/08
Filed: 1993-08-18
Abstract: A circuit tracer for determinating the location of a conductor, such as a wire, which is either an open or closed circuit, and which may lie underground. The tracer includes a transmitter which is connected to the conductor, a hand-held probe, and a re-ceiver which is connected to the probe. The probe has three different sensors:  an electric field sensor (62), primarily for locating the terminus of an open-ended conductor or for distinguishing such a wire in a bundled cable or wires; a differential electric field sensor (64, 66), for determining the direction to and location of an open-ended conductor located above ground; and an inductive sensor (68) for determining the direction to and location of a current-carrying conductor, including an open-ended conductor ly-ing below ground. A switch selectively provides the output from one of the sensors to the receiver unit, which determines the mag-nitude of any signal based upon the direction the probe is pointing. By swinging the probe back and forth, and observing the re-ceived signal, the direction to and location of the conductor may be determined.

Title: Animal fluid applicator
Inventor: GROSS ANDREW M
IPC: A01K13/00
Filed: 1995-04-11
Abstract: A free-standing animal fluid applicator comprising a frame constructed from pipe having two spaced upright members.  Two mechanism support hanging arms are pivotally attached to upper end portions of the upright members.  The heights of the hanging arms are adjustable to the heights of differently sized animals.  A vessel extends between the hanging arms.  The bottom of the vessel has two downwardly directed valves.  Below the valves is an open trough having a cotton material hanging therefrom.  When an animal passes through the cotton portion, it pulls a chain which is guided to pull down on an exterior end portion of a rocker arm.          The interior end portion of the rocker arm lifts one end of a valve closure member.  The other end of the valve closure member moves downwardly opening the valves.  The fluid then runs down through the valves, into the trough; it then soaks the cotton which rubs the animal applying fluid thereto.
