Patent CA-2188002-A1 (CA)
Inventor: YEUNG PETER KWAN WAH
IPC: F24C7/06
Filed: 1996-10-16
Abstract: A supplementary electric range heating element having a spiral coil arranged in concentric rings of successively greater elevation for heating cooking pans having curved lower surfaces, such as woks. The supplementary heating element is used in conjunction with a separate, primary heating element having a planar heating surface of conventional design. A modified support tray is also provided for supporting the primary heating element on a lower ledge thereof and supporting the supplementary heating element on an upper edge thereof surrounding the primary element. Each heating element has its own terminal which is insertable through a side slot formed in the support tray into a respective element block. Each element block is preferably wired to a separate switch so that the primary and supplementary heating elements are independently controllable. The combined wattage of the primary and supplementary heating elements exceeds that of a conventional element and is therefore better suited for stir-fry cooking techniques. The combined elements are also particularly well adapted for use with woks having flat bottoms and curved sides.

Title: Apparatus and method for a highly parallel pipetter
Inventor: GORDON STEVEN J
IPC: G01N35/10
Filed: 1995-05-11
Abstract: An actuator (18) operates an upper plate assembly (14) which holds a plurality of metal rods (40), such that all the rods are moved together along parallel longitudinal axes into respective tubes (42). The plurality of tubes (42) is held by a lower plate assembly (16), a different tube (42) for each rod (40). Liquid (sample fluid) is drawn into the individual tubes (42) by the actuator (18) raising the upper plate assembly (14) with respect to the lower plate assembly (16) and hence causing the rods (40) to simultaneously traverse the length of the respective tubes from the distal ends of the tubes (42) to the proximal ends of the tubes (42). The collected liquid is dispensed by the actuator (18) lowering the upper plate assembly (14) such that the metal rods (40) are simultaneously lowered into the corresponding tubes (42). The rods (40) are lowered very rapidly and stopped abruptly. This imparts sufficient velocity to the collected sample fluid within the tubes (42) such that the samples under inertia separate from and cleanly exit the distal ends of the tubes. As such, low volume (microvolume) dispenses are enabled in a manner free of sample contact with the target (receiving) tray (58).

Inventor: ECKMAN HAROLD J
IPC: F24H9/06
Filed: 1996-12-06
Abstract: An improved baseboard heater and method of manufacturing the same is provided.  The baseboard heater has a back panel with at least one perforation therethrough for receiving a fastener.  The perforation is comprised of intersecting slits through the back panel.  Prior to receiving the fastener, the perforation is closed or essentially undetectable.  A fastener can be easily inserted through the perforation without the need for additional tools or for drilling holes.  The perforations are made by piercing the back panel with a die piece.  The back panel is then passed between rollers to close the perforations, or to press the pierced metal flush with the remainder of the back panel.  The baseboard heater has a heater rod with fins attached in a manner to restrain their movement on the heater rod.  Hemi-spherical or conical indentations on the collar of the fin protrude into corresponding, similarly-shaped indentations on the heater rod.  The specially configured indentations are formed by opposing press elements, at least one of which has a protrusion for forming the corresponding indentations.

Title: Installation tool with selectable pintail collector
Inventor: ROSIER HENDRIK E
IPC: B21J15/06
Filed: 1995-09-07
Abstract: A pintail fastener installation tool includes a nose piston cylinder (12) which surrounds a nose piston (14) having bore (20) which is aligned with a jaw opening (22) of a nose assembly (30).      The nose piston (14) also has a venritri bore (50) which meets the bore at an angle. When connected to pressurized air the venturi bore (SO) creates a venturi effect which suctions detached pintails out of the nose assembly (30) into a container (100). The venturi bore (50) is disabled by a slide valve (56) which separates the venturi bore from the air feed. The slide valve includes a ring (58) which is positioned around the exterior of the nose piston cylinder. The slide valve (56) is slidable between a position, which allows pressurized air to flow from the air feed to the venturi bore, and a position, which prevents air flow from the air feed to the venturi bore.

Title: Single-wire guidance system for drilling boreholes
Inventor: KUCKES ARTHUR F
IPC: E21B47/022
Filed: 1995-11-08
Abstract: A single guide wire system for use in continually directional drilling of boreholes, includes a guidewire extending generally parallel to the desired path of the borehole (14). The guidewire (20) is connected at a first end (20) to one side of a reversible source of direct current (30), and at a second end (22) to ground (24). A second side of the DC source is also connected to ground (32). A known current flow in a first direction for a first period of time and in a second direction for a second period of time produces corresponding static magnetic fields in the region of the borehole (14). The vector components of the fields are measured in the borehole by a 3-axis magnetometer, and from these vector components the effects of the Earth's magnetic field are canceled and the distance and direction from the borehole to the guidewire are determined. These values permit control of further drilling of the borehole along a desired path.
