Patent CA-2149645-A1 (CA)
Title: Method of deposition
Inventor: THOMSON JAMES
IPC: G03F1/68
Filed: 1993-11-19
Abstract: 2149645 9411787 PCTABS00032 There is described a method of chemically depositing a substance.  The method is of utility in the direct manufacture of integrated circuits and in the manufacture of a photomask for use in production of integrated circuits. The method involves the use of a compound which degrades into a deposit and a residue when a radiant beam (e.g. a laser beam) or a particle beam (e.g. an electron beam) is applied. The residue and any unreacted compound may be washed off the substrate to which it has been applied. Nanoscale dimensions of the deposit can be achieved. A particularly suitable organometallic compound is tetra-sec butyl diaurum difluoride.

Title: Pumping process for operating a multi-phase screw pump and pump
Inventor: ROHLFING GERHARD
IPC: F04C13/00
Filed: 1994-04-28
Abstract: The invention relates to a pumping process for operating a multi-phase screw pump with at least one feed screw surrounded by a housing having at least one intake stub on one side and at least one discharge stub at its top, in which the intake medium is conveyed parallel to the screw shaft in a continuous low-pulsed stream and continuously discharged at the discharge stub.  The invention also relates to a multi-phase screw pump. In order to prevent the drawbacks usually occurring in dry running phases, the invention proposes that a partial liquid volume flow (liquid circulation) be separated on the pressure side and returned in metered quantities into the intake region and thus kept in circulation.

Title: Apparatus and process for cleaning polluted ground material
Inventor: KANITZ JURGEN
IPC: B09C1/06
Filed: 1994-06-02
Abstract: The present invention concerns an apparatus and a process for cleaning polluted ground material which is finely divided in a first step and heat-treated in a second step. The apparatus for cleaning polluted ground material has a pre-dividing device (4 5, 6) and a heat treatment station. To provide an apparatus and a process of the above-indicated kind which permit highly efficient removal of volatile substances from the ground material at a comparatively low energy consumption and at low cost it is proposed in accordance with the invention that in regard to the process the ground material is heated in the second step without contact with an open flame by way of heat exchangers to a temperature above the boiling temperature of water and below a temperature of 400°C and then the heated fine-grain ground material is exposed to hot, possibly superheated steam which removes the volatile constituents from the ground material grain. In regard to the apparatus it is proposed that the heat treatment station is an evaporator (10) at which there are provided heating devices (21, 11) circulating and conveying devices (11) and at a spacing from an intake of material into the evaporator (10) a steam feed device (12) for the feed of steam which is heated above the water condensation temperature to the ground material which is also heated in that region above the condensation temperature.

Title: Electric lamp with reflector
Inventor: ANSEMS JOHANNES PETRUS MARIA
IPC: F21Y101/00
Filed: 1995-03-24
Abstract: The electric lamp (10) with reflector (1) has a concave reflecting surface (3) of a rotationally-symmetric general shape, onto which flat four-sided facets (7) are superim-posed which are tangent to the general shape. The facets each illuminate a rectangular field (DP) in a plane (P) perpendicular to the opti-cal axis (4) of the reflector (1), which fields are of equal shape and size and have the same orientation.  Thereby, the electric lamp with reflector is able to illuminate a rectan-gular field with a high degree uniformity and of efficiency.  The electric lamp with re-flector may be used in an image-projection apparatus.

Patent CA-2173917-A1 (CA)
Inventor: POMPEI MANUELA
IPC: C08L21/00
Filed: 1996-04-11
Abstract: The invention relates to a rubber tire composed of carbon black reinforced rubber carcass and having a rubber tread which is quantitatively reinforced with an electrically non conductive filler pigment such as, for example silica, and which, in turn, is at least partially, and preferably substantially, enveloped by carbon reinforced rubber of a consistent, or continuous, composition.   In one aspect, said rubber layer extends across at least a portion of the outer surface of the tread which is normally intended to be ground-contacting and envelops both the ends and optionally an inner surface of a tire tread, which may be a tread cap of a tread of cap/base construction.     The said rubber layer connects with at least one other carbon black reinforced rubber component of the tire in a manner to provide a path of reduced electrical resistance from said layer on the outer surface of the tread to the bead portion of the tire carcass and, therefore, such a path from the vehicle to a road surface.     In one aspect, it is envisioned that the tread construction may be a dual extrusion of (i) said tread rubber, and (ii) said rubber layer composed of tread wings and associated rubber layer extension over the outer surface of the tread.

Inventor: BRUGGER JAMES M
IPC: G01F1/708
Filed: 1996-06-06
Abstract: A flow  rate  of a fluid  flowing in  a tube  is quantitatively determined by altering the electrical conductivity of the fluid by injection of a bolus of saline.  The electrical conductivity of the altered conductivity is measured over the time it takes the altered conductivity  fluid to pass a conductivity measuring location.  The measured conductivity is integrated over the time it take to pass the conductivity measuring location.  The integral is interpreted to determine the flow rate.

IPC: B08B15/00
Filed: 1996-10-31
Abstract: A magnetically-attached exhaust nozzle assembly for use as part of an exhaust extraction system for a fire truck includes an annular nozzle locator ring which is designed to slide over and secure to the exhaust pipe of the fire truck. The nozzle locator ring includes an inner sleeve which fits closely against the outside diameter of the exhaust pipe and an outer sleeve which receives a flexible exhaust nozzle. The exhaust nozzle is integrally connected with a flexible hose of the extraction system and establishes sealing engagement at two locations on the nozzle locator ring. There is axial sealing by abutment up against a flange of the nozzle locator ring and circumferential or radial sealing due to the fit of the nozzle on the outside surface of the outer sleeve.  The flexible exhaust nozzle includes a guide rail which helps with the initial alignment and a magnet housing which ultimately attaches by magnetic attraction to the surface of the exhaust pipe for securely holding the nozzle in position.  A spring-biased locator pin helps to keep the magnets of the magnet housing spaced from the exhaust pipe during initial assembly.
