Title: Compressor discharge temperature control for a variable speed compressor
Inventor: DUDLEY KEVIN F
IPC: F25B49/02
Filed: 1991-08-01
Abstract: ABSTRACT OF THE DISCLOSURE            In an air conditioning system with a variable speed compressor drive, the discharge temperature is sensed and if it is found to exceed a predetermined threshold limit for a predetermined period of time, then the compressor speed is reduced by an incremental amount. If this condition persists, the compressor speed will continue to be reduced in incremental steps until the temperature of the discharge gas is reduced to a level below the predetermined threshold limit.

Title: All purpose integral rivet and method of forming same
Inventor: SCHUBERT JAMES R
IPC: B65D17/34
Filed: 1991-10-29
Abstract: Abstract of the Disclosure An improved integral rivet button and resulting rivet, and a process and tooling for forming such button, utilizes successive coining steps on material surrounding the base of an initial bubble formed on a can end, causing flow of material along the wall of the button toward its center. The successive coining at progressively lesser radii affords adequate metal in the bubble region to assure ultimate formation of an accurate button, assures a strong boundary region about the base of the button, and assures the rivet head is sufficiently large to prevent tear out of the tab at its juncture with the rivet.  The initial coined boundary is located close to the juncture of the initial bubble wall with the remainder of the shell, where curvature of the initial bubble wall is concave in the direction of the bubble top and toward the ultimate public side of the end. Subsequent coining at one or more locations radially inward from the initial coined boundary causes material to flow into the region from which the button ultimately is formed, and such material is reshaped into a precise button form having improved overall thickness and strength.  Tooling design is such that intermediate shapes formed at progressive tool stations are compatible with next tooling stations to promote smooth transition of metal.

Patent CA-2056199-A1 (CA)
Title: Treatment of gas
Inventor: RATHBONE THOMAS
IPC: F25J3/04
Filed: 1991-11-26
Abstract: ABSTRACT TREATMENT OF GAS   A gas stream comprising hydrogen sulphide is partially burned in a furnace 2 to form sulphur dioxide and water vapour.  Some of the sulphur dioxide reacts with some of the residual hydrogen sulphide to form sulphur vapour and water vapour.  Sulphur vapour is condensed out of the resulting gas mixture in condenser 14.  Part of the hydrogen sulphide in the resulting gas mixture is then burned in a second furnace 16 to form more sulphur dioxide and water vapour.  Some of the sulphur dioxide reacts with some of the residual hydrogen sulphide to form further sulphur vapour and water vapour.  Sulphur vapour is then condensed in condenser 26.  Oxygen for the combustion of the hydrogen sulphide is provided from an air separation plant.  Nitrogen from the same air separation plant is employed at a pressure of at least 2 atmospheres to provide cooling for the condensers 14 and 26 and is thereby heated.  The resulting heated nitrogen is then expanded in turbine 52 with the performance of external work.

Title: Anti-iridescent coatings with gradient refractive index
Inventor: PROSCIA JAMES W
IPC: B32B7/02
Filed: 1992-05-12
Abstract: ABSTRACT OF THE DISCLOSURE       A substantially transparent glazing article has an optically functional coating on a transparent substrate. The coating has an optically functional topcoat layer and an anti-iridescence layer between the topcoat and the substrate.  The refractive index anti-iridescence layer is (i) higher than the refractive index of the substrate in a first high refractive index zone directly on the substrate surface, (ii) lower than that of the first high refractive index zone in a low refractive index zone directly on the first high refractive index zone, and (iii) higher than that of the low refractive index zone in a second high refractive index zone directly on the low refractive index zone.  The refractive index of the anti-iridescence layer varies in at least one of the zones substantially continuously with distance from the substrate surface.  Contiguous zones may together form a single gradient index zone.  The anti-iridescence layer is less thick than the optically functional layer and substantially reduces or eliminates iridescence without significantly impairing the optical functionality of the top coat layer.

Title: Alkyl sulphooxyalkanoate compounds and compositions
Inventor: CHO SUK H
IPC: A61K8/00
Filed: 1992-07-27
Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to novel sulfooxy alkanoates surfactants in which a portion of the surfactant molecule has a so-called "benefit reagent" function, and compositions containing these surfactants. It is believed that this benefit reagent portion comes to play when the surfactant is metabolized or hydrolyzed.            The surfactants used in these compositions are calcium ion insensitive, show mildness benefits and foam well.  Thus the surfactants have been demonstrated to be useful surfactants in addition to delivering a beneficial reagent.

IPC: E06B9/24
Filed: 1992-10-13
Abstract: Abstract of the Disclosure The invention relates to a guide rod for a fabric for window decoration or shading system, wherein the fabric can be gathered essentially perpendicularly to the guide rod. The rod comprises a pair of sliding pins (2), telescopingly mounted one at each end of the rod so as to be slidable in the longitudinal direction of the rod, each of these sliding pins (2) having a head (3), which is held by the free edges of a C-shaped cross-section of a respective one of a pair of stationary rails (1), which may be fastened to opposite sides of the frame of the window. Each sliding pin (2) has a disc (8) seated thereon adjacent the rail. The disc is pressed toward the head (3) of the respective pin by a compression spring (9) which is braced against the adjacent end of the central rod portion and acts to clamp the pin to the rail so as to frictionally maintain the pin and thus the entire rod, in desired position along the rail. The sliding pin (2) has an abutment means (6), which prevents the telescoping pin from being withdrawn from the end of the rod beyond the point at which the abutment engages a cooperating shoulder at the interior of the central rod portion.
Patent CA-2082094-A1 (CA)
Inventor: GOODWIN GEORGE B
IPC: C08J7/046
Filed: 1992-11-04
Abstract: A method and article are disclosed wherein a glass substrate is provided with a more durable non-wetting surface. High water repellancy and high lubricity are provided by perfluoroalkylalkyl-silanes which bond directly to a silica surface, preferably by treatment with a perfluoroalkylalkylsilane and a fluorinated olefin telomer on a glass surface on which has been deposited a silica primer layer in accordance with the present invention. The durability of the water and dirt repellancy of a glass surface is improved by applying a silica primer layer to the glass substrate prior to treating the surface with select fluorinated compounds. The silica primer layer may be applied to the glass surface by pyrolytic deposition, magnetron sputtering, sol-gel condensation reaction of e.g. alkyl silicates or chlorosilanes or other conventional methods. The silica primer of the present invention provides more durability to a glass surface treated with perfluoroalkylalkylsilanes for high water repellancy and high lubricity.
