Patent CA-2083446-A1 (CA)
Title: Curling Stone
Inventor: THOMPSON ALBERT N
IPC: A63B67/14
Filed: 1992-11-20
Abstract: A curling stone is manufactured of a two layered material, a main body and a bottom layer on which the running edge is formed. The two layers are joined along a flat mating surface that is readily formed on the main body usinga stone saw. The stone may be manufactured by the refurbishing of existing stones on which the running edge has been damaged or it may be manufactured as an original stone. A granite that is resistant to water penetration may be used for the bottom layer and a less expensive, more shock resistant granite for the main body, including the striking band.

Patent CA-2085724-A1 (CA)
Inventor: CHUNG YUE C
IPC: G01R19/155
Filed: 1993-02-09
Abstract: Abstract A load energized electronic test pencil including a main probe, an energy-storing circuit, a RC detection indicator, and two other probes.   During voltage testing, the energy-storing circuit is charged and energized, thereafter behaves as a built-in power supply for the RC detection indicator. Incorporated  with  a  conventional  low  impedance  voltage-indicating circuit, it can further be composed into a multi-functional electronic test pencil which can perform voltage, resistance and capacitance testing without the need of a built-in power supply.  This novel test pencil preserves the features of being simple-constructed, small-sized, inexpensive and pocketable as a conventional test pencil, yet it is more practical and advanced than the old type.   It is an ideal appliance both for electricians and for household use.
Patent CA-2088550-A1 (CA)
Inventor: LEWANDOWSKI RAYMOND D
IPC: A61M5/32
Filed: 1993-02-01
Abstract: A safety needle device includes a barrel having an inside surface defining a chamber  and an open proximal  end.   A  distal  end  includes  a  needle cannula  attached  thereto.    The  needle  cannula includes a distal tip and a lumen therethrough in fluid  communication  with  the  chamber.

Title: Surface hardened biocompatible metallic medical implants
Inventor: DAVIDSON JAMES A
IPC: A61L27/06
Filed: 1993-02-04
Abstract: ABSTRACT      This invention provides surface hardened, abrasion resistant high strength, biocompatible metal medical implants, in particular, titanium alloy implants which do not include any elements which have been shown or suggested as having short term or long term potential adverse effect from a standpoint of biocompatibility. Further, the invention provides methods of strengthening and hardening the surfaces of other titanium, zirconium, and cobalt-based alloy implants with small concentrations of a metal solute such as zirconium, yttrium, tantalum, aluminum, silicon, chromium, or thorium via internal oxidation or nitridation.  Alternatively, nitrogen, oxygen, or carbon can be diffused directly into the surface of the implants by interstitial hardening to further increase the surface abrasion resistance of these internally oxidized or internally nitridized implant metal or metal alloys.

Title: Process for recycling waste paper
Inventor: DOERFLINGER HANS-DIETER
IPC: D21B1/32
Filed: 1993-03-04
Abstract: PROCESS FOR RECYCLING WASTE PAPER     ABSTRACT OF THE DISCLOSURE      The invention concerns the recycling of waste paper in a deinking process with flotation with at least one other cleaning stage downstream.    According to the invention, selective flotation is performed in multiple stages.    After no more than a third flotation stage, the flotation foam collected up to that point is removed and purified by means of flash flotation, which produces sludge, clear water and separated foam that contains the contaminants from the waste paper feed.          Subsequently, the sludge is removed from the paper recycling process.    Large impurities are removed from the sludge (foam)  (except for the foam from up to the three last stages) in up to two washing units (including thickeners) or screen units.  The fibers are then separated from the relatively fine contaminants, and these contaminants are primarily removed as sludge from the resulting low-fiber fractions by flash flotation.  The fiber-containing fraction and the clear water from flash flotation is recycled to a point prior to the selective flotation system.

Patent CA-2092883-A1 (CA)
Inventor: HOHMANN RALF
IPC: B25B23/153
Filed: 1993-03-29
Abstract: A screw can be driven home in response to the application of a preselected torque by placing over the head of the screw a tubular first section of a plastic adapter wherein the first section is connected with a polygonal second section by a frangible joint.  The joint breaks in response to the application of preselected torque to the second section, and the separated second section then expose a destructible diaphragm which is provided in the first section and overlie the head of the screw.  The head can be engaged by the working end of a tool in response to at least partial destruction of the diaphragm.  The first section can be of one piece with the head or it can be affixed thereto by an adhesive or is in mere frictional engagement with the head.  Integrity and accessibility of the diaphragm indicate that the screw was driven home in response to the application of preselected torque as well as that the head of the screw was not tampered with subsequent to separation of the second section from the first section of the adapter.

Title: Tubular Hitch Member Ball Connection for an Implement
Inventor: ESSEX DUANE A
IPC: A01B59/00
Filed: 1993-07-15
Abstract: Hitch ball assemblies for implement hitches are welded directly into holes formed in sidewalls of tubing ends which have been flattened to provide direct load transfer from the tubing to the implement frame.  Several different flattened end cross-sectional configurations provide strong ball joint areas with a pleasing appearance.  In one embodiment, an additional plate is supported between the sidewalls prior to flattening, and the hole is formed in the two sidewalls and the plate in the same hole-forming operation.  The reduced number of hitch parts and welding steps decreases cost and dimensional variations.

Patent CA-2102197-A1 (CA)
Inventor: EDWARDS RICHARD C
IPC: G01J5/04
Filed: 1992-01-21
Abstract: A wafer processing cluster tool (10), having one or more load-locks (32, 34), is provided with one or more batch preheating modules (42, 44) that receive wafers only from the cluster tool transport module (12, 14) at the internal vacuum pressure of the machine. The loading, unloading, handling and processing of wafers in the machine can occur while other wafers are being preheated. The preheat module has a vertically moveable rack (64) and is loaded with various sized batches of wafers with no vacant positions between them. Wafer shaped shields may occupy positions adjacent top and bottom wafers to cause them to heat the same as other wafers in the rack. Infrared lamps (90) positioned outside of quartz windows (60) heat wafers in the preheat module. The rack may rotate to improve heating uniformity. Temperature sensors (93, 94), such as pyrometers, that do not contact the wafers being preheated, measure temperature for control of the heating of the lamps.
