Patent CA-2048107-A1 (CA)
Title: Liquid crystal projection apparatus
Inventor: INADA TOMOHIDE
IPC: H04N9/31
Filed: 1991-07-30
Abstract: ABSTRACT OF THE DISCLOSURE A liquid crystal color projection apparatus includes a light source, dichroic mirrors, transmission type liquid crystal panels, a beam mixing section, two parallel side plates, and bar members.  The dichroic mirrors separate light, supplied from the light source, into red, green, and blue beams.  The transmission type liquid crystal panels are respectively arranged on the optical paths of the three color beams separated by the dichroic mirrors so as to form images corresponding to the three color beams.  The beam mixing section mixes image beams from the transmission liquid crystal panels to reproduce a color image.  The side plates have plural pairs of engaging portions, arranged at symmetrical positions, for fixing the dichroic mirrors and the liquid crystal panels at predetermined positions.  Each of the bar members has two end portions fixed to one pair of engaging portions of the side plates, thus fixing and holding two arbitrary end portions of each of the dichroic mirrors and the liquid crystal panels thereon.

Title: Tank monitoring system
Inventor: GREGORY EDWARD M
IPC: G01F23/28
Filed: 1991-08-02
Abstract: TANK MONITORING SYSTEM            ABSTRACT OF THE DISCLOSURE     The height of a liquid level from the bottom of a storage tank or the like is accurately determined by using a probe with dual isolated channels to measure the time for an acoustic signal to travel between fixed submerged points and from a transducer in one of the channels to the surface of the liquid. Elapsed time measurements are converted to liquid volume using predetermined velocity-temperature values to compensate for temperature variations in the tank.

IPC: G02B6/38
Filed: 1990-06-13
Abstract: High strength optical fiber splices are obtained using an inert flowing gas (82) to remove frit and discoloration produced during a fusing process. The fibers (50) being spliced are protected from chemical and particulate contamination by preventing such contaminants from coming into contact with the exposed fiber ends as can occur when the fiber end is placed into a solvent to soften the jacket prior to stripping. Finally, a post fusion heat treating step is added after the fibers have been spliced to re-move any surface damage that may have been produced.

Abstract: ABSTRACT     A flushing mechanism and method of reducing the flushing volume of a cistern A method of reducing the volume flushed from a toilet cistern during a full flush.  A forcing means is provided part way along a tube connected to a valve means of a toilet cistern.          As the water level in the cistern lowers about the forcing means it applies downward force which closes the valve means at a predetermined water level.   In this way the maximum volume of water flushed from a cistern may be varied for any cistern  without  reducing  the  maximum  head  of  pressure available.

Title: Dipping composition for the treatment of chromatized or passivated galvanizing coatings
Inventor: FLAMME BURKHARD
IPC: B05D7/00
Filed: 1992-11-16
Abstract: A dipping composition for the treatment of a chromatized or passivated zinc or zinc alloy coating deposited on a steel substrate is disclosed. The composition comprises titanic, acid esters, titanium chelates or mixtures thereof, organo-functional polysiloxanes and a solvent selected from the group consisting of organic solvents, preferably alcohols and hydro-carbons, water and mixtures thereof. The weight ratio of titanic acid esters to polysiloxanes in the composition is from about 1:1 to about 1:4. Using the composition, a coating having thickness of, for example, 4 to 6 microns can be applied using a dipping process, which coating is subsequently dried at 80°C and burnt in at up to 250°C. The coating so obtained provides corrosion protection times at least 5 to 10 times longer than those which may be achieved without it. In particular, it can be used to improve the corrosion resistance and durability of chromatized coatings obtained using chromium III compounds, which chromatizing, normally less durable than that obtained using chromium VI com-pounds, is preferred because of its lesser environmental impact.
