Inventor: LLOYD DAVID DOUGLAS
IPC: B04C5/081
Filed: 1997-02-06
Abstract: A dehydrating hydrocyclone having a cylindrical inlet portion (8) the length (l1) of which is at least twice its diameter (d1). The cylindrical portion leads into the tapered portion (9) the length (12) of which is at least twice the length (l1) of the cylindrical portion.

Title: Water jet propulsion device for marine vessel
Inventor: ISHIGAKI EIICHI
IPC: B63H11/08
Filed: 1997-12-08
Abstract: A pump frame (7) is fixed to a ship bottom (1b) such that an inflow port (19) in a lower portion thereof is open in the water near a stern (1a). A mixed flow pump (8) is fixed to a pedestal (12) provided on the ship bottom (1b). A  suction port (26) of the mixed flow pump (8) is connected to a connection port (17) at an upper portion of the pump frame (7), and a discharge pipe (13) is connected to a discharge port (27) of the mixed flow pump (8).

Title: Method of cutting blocks of hard substances into plates by means of a wire saw, and wire saw for carrying out this method
Inventor: VOJTECHOVSKY KAREL
IPC: B24B27/06
Filed: 1997-02-25
Abstract: The invention concerns a method of cutting blocks (1) of hard materials into plates by the action of an abrasive, which is added in the loose state and a continuous circulating fixed carrier (7). As a result of being guided in peripheral grooves in coaxial rollers (2, 3) of a roller system, the carrier forms a chain which presses through the material to be cut. The carrier, for example a sawing wire, which runs in the peripheral grooves in the rollers of a roller system comprising at least one pair of deflection rollers (2) and at least one pair of guide rollers (3), is pressed into the material to be cut such that it is guided in opposite directions in two adjacent cuts in the block.

Title: Process for producing fluorinated aromatics and fluorinated nitrogen-containing hetero-aromatics
Inventor: KLEINER HANS-JERG
IPC: C07B39/00
Filed: 1997-02-28
Abstract: The production of fluorinated aromatic compounds of general formula (I), in which W, X, Z, R1 and R2 have the meanings given in the description, from corresponding C1 or Br-containing compounds with fluorides, e.g. KF, with halogen exchange in a reaction medium, is known. According to the invention, the "halex" reaction (exchange of a halogen for fluorine) is performed in a reaction medium containing compounds of general formula (III), (IV) and/or (V) in which R16 to R24 have the meaning given in the description. This provides a particularly advantageous process in which gentler conditions may be applied while providing higher output and fewer by-products. Fluorinated aromatic compounds of formula (I), e.g. are used as intermediate products for active agent synthesis.

Title: Protective cover for an infrared thermometer
Inventor: HOWE RANDALL R
IPC: G01K1/08
Filed: 1997-05-05
Abstract: A first protective cover (8) for the probe (2) of an infrared thermometer (1) comprises a thin sidewall (31) linked to a film window (10) by a collar structure (34). The collar structure (34) includes one or more of a sill (14), first fold (12) and second fold (16) that receive any forces applied to the sidewall (31) so as to prevent the translation of these forces into a stretching force applied against the window (10). A second protective cover (8) comprises a sidewall (31) between a window (10) and a cover retention rim (71) to retain the cover (8) with the window (10) positioned over the opening of probe (2). The cover retention rim (71) provides points of contact at two separate planar locations (90, 91) on the rim (71) with the probe (2) so as to form a snug fit that precludes vertical movement of the cover (8) after the cover (8) is installed on the probe (2).

Patent CA-2260512-A1 (CA)
Title: Improved cutting matrix
Inventor: LYNDE GERALD DAVID
IPC: E21B29/00
Filed: 1999-01-28
Abstract: A method for applying cutting elements to a tool for cutting or milling a metal item in a well is disclosed, along with the cutting element used in the method. The tool can include one or more blades extending outwardly or downwardly from the tool for cutting a metal item such as the wall of a casing string, or for removing a predetermined length of a casing string in a cutting action. The blade or blades have cutting elements positioned on the leading faces of the blades to engage the casing string or other metal item in the bore hole. Each cutting element is composed of a plurality of effective cutting faces. Each cutting face can have a substantially triangular shape, or a substantially square shape, or some other geometric shape. The cutting elements can be arranged in a random pattern. Each cutting element can be oriented in a random orientation relative to the blade. The cutting elements are shaped so that, regardless of the positioning or orientation of a given cutting element, it will continually present a sharp cutting edge to the metal object being cut. Each cutting face of each cutting element can also have one or more surface irregularities to cause the metal chips cut from the casings to break off at short lengths.
Patent CA-2264163-A1 (CA)

Title: Vehicle collision warning system
Inventor: FARMER MICHAEL E
IPC: B60R21/00
Filed: 1998-02-05
Abstract: A vehicle collision warning system (10) converts collision threat messages from a predictive collision sensor into intuitive sounds which are perceived by the occupant to be directed from the direction of the potential collision.  The type and volume of the sounds are dependent upon the estimated likelihood, severity, and commencement time of the collision. The types of sounds are chosen to evoke the proper corrective action by the driver as necessary to avoid the collision or mitigate the effects thereof. Examples of the sounds include a horn, screeching tires, a siren, sounds of various types of vehicles and objects, and voice commands. The sounds are stored monaurally and are converted to directional sounds using known techniques.
Patent CA-2279881-A1 (CA)
Inventor: CHALMERS DEREK T
IPC: C07K14/72
Filed: 1998-04-14
Abstract: Les récepteurs de surfaces cellulaires se trouvent en équilibre entre un état inactif et un état actif. Jusqu'à présent les approches antérieures pour étudier la fonction des récepteurs et pour sélectionner les récepteurs destinés à permettre l'élaboration de nouveaux médicaments se sont concentrées d'abord sur l'identification du ligand endogène du récepteur (ou d'un substitut synthétique) et ensuite sur l'identification des antagonistes de ce récepteur se trouvant dans une conformation structurale inactive. Il est maintenant reconnu qu'on peut directement obtenir des informations très valables pertinentes pour le traitement de maladies causées par des récepteurs, en identifiant les composés qui agissent comme agonistes inverses des formes constitutivement activées du récepteur, c'est-à-dire ceux pour lesquels l'équilibre a été déplacé vers l'état actif. Des procédés pour activer constitutivement les récepteurs sont utilisés pour spécifier les informations génétiques codant pour les récepteurs qui sont ensuite exprimés dans des systèmes d'expression appropriés. Des dosages qui mesurent la réponse cellulaire induite par les composés agissant sur les récepteurs peuvent identifier à la fois les agonistes inverses et les agonistes du récepteur. Une sélection à fort rendement peut être utilisée pour identifier rapidement ces composés. Une caractéristique particulièrement pertinente consiste en ce que les modulateurs de l'action des récepteurs peuvent être identifiés sans connaissance préalable de la fonction du récepteur ou du ligand endogène. Le procédé faisant l'objet de cette invention est particulièrement applicable aux récepteurs orphelins.

Abstract: A light weight transportable aid for training hockey players in stickhandling techniques has four L-shaped legs which extend radially from a central hub.  Each leg has a radially extending portion which is spaced at least three and one quarter inches of all the surface of the ice. A player trains by passing a puck or ball beneath and through the legs of the training aid. Alternatively, a straight fiberglass rod extends through upwardly extending plastic supports which space the rod about 1/4 inches above the ice. A plastic coupling extends from the rod to permit multiple training aids be connected together and a single extended aid which provides training for the skater advancing along the rods.
