Patent CA-2120025-A1 (CA)
Title: Fire-Protection Valve with Shutting Spring for Automatically Shutting Off Conduits
Inventor: SCHULZE KLAUS
IPC: F16K17/38
Filed: 1992-09-22
Abstract: A fire-protection valve is disclosed with a shutting spring, for automatically shutting off conduits, in particular gas conduits, such as those that are mounted upstream of gas fittings.          The valve according to the invention comprises a metallic closure body having a spherical shape, at least in the sealing area.  Its diameter forms a slight tight fit with the diameter of the first bore shaped in the housing of the valve, when the valve is closed.      A second bore that extends in the axial direction of the first bore is arranged upstream thereof, in the direction of the closure body.  The diameter of the second bore forms a loose fit with the diameter of the closure body.  A spherical guide that tapers in the direction of the closure body in its open position is located between the closure of the second bore.  The closure body is normally seated on three fixed points, one of which is a temperature-sensitive element.  When the temperature of the element rises above a pre-determined level, the element becomes deformed and the closure spring forces the closure body through the opening between the fixed points, enlarged due to this deformation.  The moving closure body is centered on the valve axis by the spherical guide and the second bore and, due to its kinetic energy, is pressed into the first bore, producing a tight moulding fit.  After getting in touch with the housing, the closure body rapidly acquires its temperature, whereby the moulding fit increases resulting in a gas-tight connection which no longer requires the closure spring to keep the valve closed, even under shocks or concussions.

Title: Surface Preparation and Deposition Method for Titanium Nitride Onto Carbonaceous
Inventor: NIEH SIMON K
IPC: C23C14/02
Filed: 1993-08-11
Abstract: Wear-resistant titanium nitride coatings onto cast iron and other carbon-containing materials (18) is enhanced by means of a new surface preparation and deposition process. The conventional pre-deposition surface cleaning by Ar+ ion bombardment is replaced by a hydrogen-ion bombardment process which cleans the substrate surface (16) by chemical reaction with minimal sputtering and simultaneously removes graphite present on the cast iron surface.  Removal of the graphite significantly improves the wear resistance of titanium nitride, since the presence of graphite causes initiation of wear at those sites.  Hydrogen ion bombardment or electron bombardment may be used to heat the substrate to a chosen temperature.  Finally, titanium nitride is deposited by reactive sputtering with simultaneous bombardment of high-flux Ar+ ions from an independently generated dense plasma (10').  The resulting titanium nitride coating on cast iron evidences superior wear properties and adhesion compared to conventional reactive evaporation deposition techniques for titanium nitride.

Title: Septal defect closure device
Inventor: DAS GLADWIN S
IPC: A61B17/00
Filed: 1993-01-21
Abstract: The present invention provides a system and a method for closing septal defects and the like. The system includes a closure device (10) having a pair of occluding disks (20, 30) each disk being formed of membrane (22, 32) and an elastically deformable frame (24, 34) carried about the periphery of the membrane (22, 32). The frame (24, 34) which may be formed of a superelastic material is capable of being collapsed for passage through a catheter and elastically returning to predetermined shape for faulty holding the membrane. A central portion of the membrane (22, 32) of each disk (20, 30) is attached to a central portion of the other membrane to define a conjoint disk (40). The method of the invention involves collapsing the frames (24, 34) of the disk (20, 30) inserting the closure device (10) into a catheter and positioning the distal end of the catheter adjacent a septal defect. The disk (70) is then urged out of the distal end of the catheter to permit its frame (24) to elastically return to a predetermined shape, pulling the membrane (22) taut on one side of the defect. The second disk (30) is then similarly deployed on another side of the defect, automatically positioning the conjoint disk (40) within the defect to occlude it.

Said  easel consists of a generally U-shaped hook at the top that removably fastens across the top and two faces of said armature. Said easel angles out across one face of said armature to allow for the secure placement and easy viewing of books and/or documents that are held in place by a generally L-shaped extension at the bottom of the easel.
Patent CA-2133496-A1 (CA)
Inventor: KOVACS GREGORY J
IPC: H01S3/23
Filed: 1994-10-03
Abstract: The present invention is a novel multiple laser diode structure and method for using such structures to optically isolate the light from the different diodes. The novel structure comprises a submount on which the individual lasing elements are mounted and a back facet monitoring plate coupled to the submount. The back facet monitoring plate comprises a plurality of optically sensitive detectors that monitor the amount of laser light emanating from the back facet. Ideally, one detector should be mounted opposite a back facet for each lasing element. The submount is designed with an isolation bar that optically separates the light from individual lasing elements. The radiation thus detected by each detector emanates from the back facet of a single lasing element. The amount of back facet radiation captured by the detector is proportional to the amount of radiation emanating from the front facet of the lasing element. This information enables the system to individually monitor and subsequently control the spot power of the lasing element in a continuous closed loop fashion.

Inventor: ALCORN LARRY H
IPC: B08B15/02
Filed: 1995-04-05
Abstract: The apparatus of the present invention may be implemented in software which performs the following steps: calculating a desired air velocity in the exhaust duct from a first input signal representative of the side of a variable sash opening and a first user defined setpoint representative of a desired face velocity; comparing successive values of the desired air velocity to determine any absolute and percent change therebetween; comparing the absolute change to a user defined reset deadband value; producing output signals, responsive to a second input signal representative of the measured air velocity in the exhaust duct and the second comparing step, for input to the fan so as to force the measured air velocity toward the desired air velocity. The production of the output signal is accomplished by adaptive, feedforward techniques when the absolute change is greater than the reset deadband and is accomplished by proportional/integral techniques when the absolute change is less than the reset deadband.  A timer is provided to lockout the production of output signals produced by employing proportional/integral techniques for a predetermined period of time after an output signal is produced by employing adaptive, feedforward techniques.
