Patent CA-2051136-A1 (CA)
Title: An apparatus for separating sulphur and soil
Inventor: BRADLEY MAURICE E
IPC: B09C1/06
Filed: 1991-09-11
Abstract: An  apparatus  for  separating  sulphur  and  soil consisting of a liquid sulphur bath container having an upper compartment, and a lower compartment.   The upper compartment  has  a  bottom  sloping  downwardly  from  a peripheral top edge toward the lower compartment.   The upper compartment has a lower sidewall adjacent the lower compartment  with  a  liquid  aperture  whereby  liquids communicate between the upper compartment and the lower compartment.  A heating element is disposed in the upper compartment to maintain the temperature of a liquid sulphur bath.  Solid phase sulphur contaminants in soil are heated to liquid phase by the liquid sulphur bath.  As sulphur contaminated soil is placed into the liquid sulphur bath, a displacement of liquid sulphur occurs which results in a migration of liquid sulphur through the liquid aperture in the  lower  sidewall  into  the  lower  compartment  and ultimately through the outlet.  A belt conveyor extends parallel to the bottom of the upper compartment and through a slotted opening in the lower sidewall of the upper compartment  below the  liquid  aperture  into  the  lower compartment.   A layer of soil is carried by the belt conveyor  to  a  spillway  positioned  adjacent  the  top peripheral edge of the container.  The belt conveyor is of a filter material such that liquid sulphur passing through the  liquid aperture into the  lower compartment passes through the filter material of the belt conveyor thereby removing sediment from the liquid sulphur.

Patent CA-2052983-A1 (CA)
Inventor: DEVONALD DAVID H III
IPC: H02B7/06
Filed: 1991-10-08
Abstract: An interconnection arrangement is provided for the appropriate interconnection of predetermined assemblies and modules affixed to the exterior of an enclosure of pad-mounted gear, while also shielding the interconnections from the medium-voltage sections of the pad-mounted gear. The interconnection arrangement may be utilized either during manufacture of the pad-mounted gear or as a field retrofit installation. The interconnection arrangement includes a base assembly which defines predetermined enclosed cable pathways through which the interconnecting conductors are routed. The interconnecting conductors are provided by preassembled and pre-routed cable harnesses within the defined cable pathways.  The intercon-nection arrangement also includes internal and external duct structures that extend the cable pathways through the base assembly and into the individual enclosures for the assemblies and modules affixed to the exterior of the enclosure of the pad-mounted gear. The interconnection arrangement is of modular design so as to be easily configurable for installation to different configurations of pad-mounted gear and affixed assemblies. In addition to the interconnection arrangement being versatile, it also lends itself to ease of manufacture and the use of basic component parts to provide different configurations as either manufacturing assemblies or field retrofit kits.

Abstract: A two-stage high flow purge valve for an evaporative emission system of a vehicle. The valve body contains two valves for controlling fluid flow through separate parallel flow paths in the valve body. A fast-acting, pulse width modulated solenoid valve responsive to an electrical control signal from the engine control computer precisely controls flow through a low flow path, and a vacuum-responsive valve controls flow through a high flow path in accordance with the level of manifold vacuum at the engine intake.  A third valve member is provided to block flow through the high flow path when the engine is off and the manifold vacuum is zero. Means for calibrating both the solenoid valve and the vacuum-responsive valves are also provided.

Abstract: A balancing arrangement for a rotating member, especially for a hollow shaft made from lightweight metal, in which a counterweight of predetermined size and weight is affixed onto the external surfaces of the rotating member in predetermined position by the use of a clamping band made from a material normally devoid of any significant elastic stretchability. A plastically deformable ear structure is provided in the clamp structure for tightening the clamping band which includes two generally outwardly extending leg portions interconnected by a bridging portion that includes downwardly bent tab-like members along the longitudinal sides of the bridging portion to act as ramp surfaces and reinforcing elements for the ear structure. The counterweight is thereby connected with the clamping band in one place by spot-welding, particularly, when both clamping band and counterweight are made of stainless steel.

Title: High visibility tractor configuration
Inventor: WOODS TERRILL W
IPC: B62D49/00
Filed: 1992-02-20
Abstract: A work vehicle configuration has the engine directly over the front axle, the cooling system radiator far enough forward to allow even large tires to turn into the volume defined between the radiator and the engine, and a tall but very narrow transmission forward of the operator enclosure.  This allows the vehicle to be provided with a wasp-waist, significantly improving visibility. This also allows a recessed area in the vehicle body adjacent to the front tires, allowing a sharper turning radius and improved maneuverability.  This placement of the transmission frees space under the operator enclosure, allowing use of a significantly larger fuel tank.  Finally, the placement of the main vehicle components away from the front tires and out from under the operator enclosure allows improved access and serviceability for the tractor.

Patent CA-2082882-A1 (CA)
Title: A rotor type flow meter with optical detection
Inventor: TEUNISSEN THEODORA A
IPC: G01F1/115
Filed: 1992-11-13
Abstract: The flow meter has in a substantially cylindrical inner housing (1) a helically designed diffusor (4), which imparts a swirl to the medium flowing through the inner housing. Downstream of the diffuser there is rotatably mounted a rotor (8), which has blades (13) extending from its rotational spindle (9) as well as a ring (14) which connects the blade ends to one another and is coaxial to the spindle. The rotor (8) is set in rotation by impingement of the blades (13) by the flowing medium. On the outer circumferential surface (15) of the ring (11) there is on a circular line a multiplicity of markings (16) arranged at equal angular intervals from one another. Through a window (18) in the inner housing (1), a light beam strikes the outer circumferential surface (15) of the ring (14), provided with the markings (16). Upon rotation of the rotor (8), the sequence of the. markings is transmitted by an optical-fibre cable (20) and sensed by a sensor (21), so that from the signals received the flow rate can be determined. The flow meter has the advantage that the medium to be measured does not have to be transparent as in the application of the light barrier and that the multiplicity of markings allows an increase in the measuring accuracy.

Title: Cat waste elimination system
Inventor: WALTON ROBERT W
IPC: A01K1/01
Filed: 1992-11-17
Abstract: ABSTRACT OF THE DISCLOSURE    A total system to remove, store and dispose of feline (or other animal) bladder and bowel movements through the introduction of and a complete utilization of many features and sub-systems to provide ways of operating and managing a fully sanitary method of wet and dry feline bladder and bowel excretions.  The system encompasses a unique urine "purification by exposure to air process," via aeration.  It uses the aerification process by having the urine go through a sand or other porous material in a top tray and then through a pervious bottom of said top tray, thence dropping on a suspended porous aeration tablet or pad.  This produces an aerified urine.  The process is preferably aided by special chemicals implanted in the aeration tablet which is multi-layered.  This then dries the urine, producing no odor, and provides a complete, disposable, sanitary, odorless system of urine deposits.  The bowel movements lodge into the dry porous material for burial by the feline and/or disposal by the cat's owner, thus reducing to negligible any stool odor as there is no element to sustain a wet buried stool, as the sand or other porous material is dry.
