Patent CA-2029426-A1 (CA)
Inventor: DERR WALTER R JR
IPC: C10G47/20
Filed: 1990-11-07
Abstract: High octane gasoline and high quality distillate are co-produced by a hydrocracking process in which a catalytic cracking light cycle oil is hydrocracked under conditions of low to moderate hydrogen pressure and severity to produce a high octane, hydrocracked gasoline. The distillate fraction which boils immediately above the gasoline fraction is recycled to the hydrocracker to increase the paraffinic content of this fraction by partial saturation and cracking of the aromatics contained in it so as to form a paraffinic distillate of low sulfur and high cetane index which is useful as a road diesel fuel. A higher boiling distillate fraction of relatively lower aromaticity may also be produced for use as a low sulfur fuel oil. The recycled fraction may be cooled to provide quench for the hydrocracker.

Patent CA-2031804-A1 (CA)
Inventor: TEARE JOHN W
IPC: B32B13/14
Filed: 1990-12-07
Abstract: The invention relates to a light-weight concrete construction panel having a layer of reinforcing mesh bonded to each of the two faces. Such panels are used on walls and floors as backerboards for the installation of ceramic tile and other facing materials. In this invention the web of mesh or other fabric wraps around the edge of the panel and is bonded in place on the top and bottom faces. The strip of mesh covering the edge is left unbonded and open; when two panels are placed abutting each other the unbonded strip of mesh along the edge captures the mortar that is applied to fill the joint. This permits improved edge-to-edge bonding.

Title: Metal pouring method and apparatus
Inventor: GRIFFITHS WILLIAM A
IPC: B22D41/38
Filed: 1991-01-15
Abstract: ABSTRACT:            METAL POURING METHOD AND APPARATUS      Flow of molten steel from a tundish to a continuous casting mould is controlled by a sliding gate valve.   The gate valve comprises a stationary refractory member having a metal pouring orifice and a slidable refractory member also having a metal pouring orifice and movable between an open condition in which its orifice is aligned with the orifice of the stationary member, and a closed condition in which the two orifices are out of alignment.  Freezing of molten steel at the sliding gate valve when it is closed is prevented by imparting an incremental stepping motion to the slidable member in its closed condition.

Filed: 1991-03-28
Abstract: ABSTRACT OF THE DISCLOSURE     A  silica-based coating for, and a method for coating glass, metal, ceramic, and plastic surfaces by forming single cross-linked O-Si-O polymer chains. The coating generally comprises a binder and a filler.  The binder is a mixture of silica-based polymers, colloidal silica, and metal oxide particles in an aqueous suspension.  It includes four main ingredients: an alkali metal silicate; silica gel; a cross-linking agent such as methyltrimethoxysilane or tetraethoxysilane; and water.  After curing, the binder forms an amorphous layer that binds the fillers to the surface.  The protective coating is formed at room temperature, without the addition of energy in any form.  The fillers are chosen to provide the coating with mechanical strength, abrasion resistance, and increased corrosion resistance.  Fillers may also be chosen to modify the coating's dielectric constant, to improve the coating's surface lubricity, and to alter the coating's thermal coefficient of expansion.  Typical fillers include clay, wollastonite, nepheline syenite, talc, flint, ceramic fibers, metallic fibers, ceramic microspheres, glass microspheres, cerium dioxide, and dichromium trioxide.
Patent CA-2040850-A1 (CA)
Inventor: KAMPER HANS-WERNER
IPC: F16G11/12
Filed: 1991-04-19
Abstract: A tensioning assembly for the stepwise tightening and releasing of a tensioning strap includes a frame (1), a tensioning lever (2), and a wind-up spindle (4) supporting ratchet wheels (3, 3').  A driving pawl (19) which is movably mounted on the tensioning lever (2) serves to rotate the wind-up spindle (4) when the strap is being tightened.          Reverse rotation of the wind-up spindle (4) is prevented by a pair of locking pawls (5, 5') which are movably mounted on the frame (1).  The lower or bearing end of the tensioning lever (2) has an unlatching cam (37) which permits the locking pawls (5, 5') to be alternatingly moved out of engagement with the teeth of the ratchet wheels (3, 3'), thus promoting safety by relieving the strap tension in stages.          An isolating cam (40) at the bearing end of the tensioning lever (2) permits both locking pawls (5, 5') to be disengaged after the strap tension has been reduced.

The rings have opposed, radially extending faces, one of which has a plurality of downstream pumping spiral grooves extending from one circumference. The grooves of the grooved ring of the upstream module have a pattern which upon shaft rotation creates shear heating of the liquefied hydrocarbon fluid. The pattern has a land/groove surface area ratio greater than one and preferably a ratio of approximately three. The dam portion relative to groove portion surface area is also preferably greater than one and the preferred dam/groove ratio is approximately three.

A demodulator and filters circuit for demodulating the modulated carrier signal and recovering the modulating signal therefrom is connected to the output  of  the  sense  amplifier.    The  modulating  signal  is proportional to instantaneous stroke volume of the patient's heart and the demodulator and filters circuit develops a control signal therefrom called a stroke volume signal.  The control signal is applied to the pulse generator so as to control the rate of stimulating pulses.

Title: Wavelength detecting apparatus
Inventor: WAKABAYASHI OSAMU
IPC: G01J9/02
Filed: 1991-02-15
Abstract: ABSTRACT    A wavelength detecting apparatus which assures that the wavelength of a laser light (1) or the like can be detected with a  high accuracy  is disclosed.   With the wavelength detecting apparatus of the present invention, the temperat-ure of a vapor obtained from a specific element such as a mercury or the like containing plural isotope is elevated in excess of a predetermined temperature so that an oscillation line of the specific element is divided into plural oscilla-tion lines.  One of the divided oscillation lines is used as a reference light (Lb) so as to practically detect the wave-length of  a  light  (La)  to be detected.   In addition,  a specific isotope contained in the specific element such as a mercury or the like is selected from plural isotopes contai-ned therein so as to practically detect the light (La) to be detected under a condition that an oscillation line derived from the vapor of the specific isotope is used as a refere-nce light (Lb).  Since each of the divided oscillation lines or an oscillation line derived from the specific isotope has a narrow wavelength width, the position of an interference fringe (8a) appearing on the detecting surface of an optical detector (8) can be detected at a high accuracy when the oscillation line is irradiated toward the detecting surface of the optical detector (8).  Additionally, the wavelength of the light (La) to be detected can practically be detected at a high accuracy based on a difference between the posit-ion where the interference fringe (8a) is detected and the position where an interference fringe (8b) appearing on the detecting surface of the optical detector (8) is detected when the light (La) -to be detected is irradiated toward the detecting surface of the optical detector (8) as well as a known wavelength of the oscillation line.  When the wave-length detecting apparatus of the present invention is used to detect the wavelength of an excimer laser light oscilla-ted by a narrow-band oscillating excimer laser light unit, oscillation of the excimer laser light can be stabilized within the narrow-band oscillatory range by properly contro-lling the wavelength of the excimer laser light based on the detected wavelength.  Further, with the wavelength detecting apparatus of the present invention, the detected wavelength can be unchangeably maintained at  a high accuracy while assuming a preset wavelength.
