Patent CA-2127510-A1 (CA)
Title: Temperature Sensor Probe and Sensor Detection Circuit
Inventor: JONES THADDEUS M
IPC: G05B9/02
Filed: 1994-07-06
Abstract: A sensor probe and sensor detection circuit used  in an electronic temperature control circuit for preventing the control circuit from driving an external device such as a heater when the sensor probe has been disconnected from the control circuit.  The sensor probe includes an NTC thermistor and a limiting resistor that are connected in parallel and potted in epoxy.  The thermistor and limiting resistor of the sensor probe form part of a lower leg of a voltage divider in the control circuit.  The sensor detection circuit compares the voltage signal generated by the sensor voltage divider to a predetermined threshold or ceiling voltage value.          During normal operation, when the sensor probe is attached to the control circuit, the resistance of the sensor probe insures that the voltage signal from the sensor voltage divider remains within a predetermined voltage range and does not exceed the predetermined ceiling voltage value.  When the sensor probe is disconnected from the control circuit, the resistance of the sensor voltage divider is decreased and the voltage signal exceeds the ceiling voltage value.  When the voltage signal exceeds the ceiling voltage value, the sensor detection circuit interrupts the normal operation of the control circuit and shuts down the heater.

Patent CA-2139863-A1 (CA)
Inventor: HOGEN DELMAN R
IPC: B09C1/10
Filed: 1993-07-08
Abstract: Methods for treating aqueous/sedimentary systems, sediments and soils are disclosed for prevention of activation and for control or clean-up. The method involves intentionally adding to an aqueous system containing unwanted sulfur and phosphorus in the water and hydrocarbons in the sediment, iron species selected from the group consisting of elemental iron, iron carbonates and iron oxides. Iron-phosphorus compounds and iron-sulfur compounds are precipitated and thereby removed from the system. Hydrocarbons are converted into water, carbon dioxide and small amounts of methane. In a practice of this invention, propagation of aquatic vegetation dependent upon phosphorus species and sulfur species is inhibited by the removal of these species therefrom. Heavy metals are inactivated.

Abstract: An  indexable  cut-off  saw  is  used  for  cutting  metal components,  e.g.  cutting a bearing cap cluster into separate caps.  The saw has a circular tool body for mounting on an arbour and this tool body has  flat side faces and a narrow outer periphery.   A plurality of circumferentially equally spaced cutting inserts are mounted at the outer periphery of the tool body, these inserts being arranged in groups of three such that the total width of the saw cut is divided between the actions of three cooperating cutting inserts.   These three cooperating cutting inserts include a central insert mounted centrally on the outer periphery of the tool body and left and right side inserts mounted in pockets extending into the side faces of the tool body.   The left and right  side inserts  are of rectangular configuration presenting  straight  cutting  edges,  while  the central cutting insert of each group presents a curving cutting edge.  The central cutting insert is preferably in the form of a cylindrical cutter disc with flat side faces providing a cutting edge disposed about the periphery of a side face.  Each cylindrical cutter disc is mounted on a side face thereof at an angle within about 1-15° of coincidence with the direction of travel of the insert during cutting.  It is also possible to use as the central cutting insert a circular cutting disc mounted axially into a pocket in the periphery of the tool body.

Patent CA-2153186-A1 (CA)
Inventor: SENSENIG DARRYL L
IPC: E04B1/86
Filed: 1995-07-04
Abstract: This invention describes two products both with a plain, fine textured, nonperforated surface visual consisting of a fiberboard substrate with or without a laminated porous nonwoven scrim and then a finished painted surface. The finished painted surface decorates or finishes the board, but most important, must remain acoustically transparent to retain the sound absorption properties of the fiberboard prior to painting. The fiberboard substrate is made to be porous or modified with hole perforations to cause it to be a good sound absorber. If the fiberboard substrate is sufficiently porous without hole perforations, then the sprayable, high solids, porous paint can be directly applied. If hole perforations are used to improve the sound absorption properties of the board substrate, then a porous, nonwoven scrim is attached and painted using the same high solids porous paint. This painted scrim must be sufficiently optically opaque to hide the hole punched board, yet sufficiently open to render it acoustically transparent.

Title: Syringe plunger with intermediate pushing surface
Inventor: MINKUS MARC STEVEN
IPC: A61M5/315
Filed: 1995-07-19
Abstract: The present invention is directed to a syringe plunger for use to administer a solution from a syringe of the type having an axially slidable piston sealing an axially extending barrel having a nozzle. The plunger includes a rigid stem member axially extending from a distal end to a proximal end. The plunger also includes threads or other attaching means at the proximal end of the stem for removable attachment to the slidable piston. The stem member includes a first surface at the distal end of the stem for application of axial force to the stem so as to move the slidable piston in the barrel. Advantageously according to the invention, the stem also includes a second surface at an axially intermediate position on the stem for alternative application of axial force to the stem so as to initially move the slidable piston in the barrel, which is especially convenient for syringe users with small hands.

Title: Conserved motif of hepatitis c virus e2/ns1 region
Inventor: WEINER AMY J
IPC: C12P21/02
Filed: 1994-05-03
Abstract: The hypervariable region (E2HV) of the putative hepatitis C virus (HCV) glycoprotein F2/NS1, between about amino acid 384 to about amino acid 414, is a rapidly evolving region of HCV, and is likely to be under positive immune selection. A newly discovered motif within this hypervariable region is immunogenic and conserved with respect to the character of the amino acids. In many isolates, this motif falls between amino acids 401 to 406 or 407. The discovery of this motif allows for additional materials and methods to treat and diagnose HCV.
