Title: Method for detecting contamination and/or damage in a face running through a nip in a paper machine or in a paper finishing machine
Inventor: MAEENPAEAE TAPIO
IPC: D21F7/00
Filed: 1998-10-19
Abstract: The invention concerns a method for detecting contamination and/or damage in a face (11, 12') running through a nip (N) or nips in a paper machine or in a paper finishing machine, such as a calender or a coating device. In the method, vibrations formed in connection with constructions of the machine are detected and processed. The vibrations are detected by means of at least two detectors (20, 21, 25). Based on the point of time of detecting of the vibrations detected by means of the detectors (20, 21, 25), the location of the damage and/or contamination (M; M1, M2) on the face (11, 12') to be monitored is determined.

Patent CA-2277640-A1 (CA)
Inventor: OTOSHI KOTA
IPC: H02M7/538
Filed: 1999-07-19
Abstract: A DC-to-AC converting circuit generates an alternating current by alternately switching a set of switching elements. The alternating current is supplied to a load Lo via an output filtering circuit. If a current detection resistor R1 in the DC-to-AC converting circuit detects an output current that exceeds a reference voltage Vref corresponding to an over-current set value, certain switching elements are turned off to disconnect the DC-to-AC converting circuit from the power source. However, the DC-to-AC converting circuit continues to generate an alternating current from energy stored in one or more inductors that are coupled to the DC- to-AC converting circuit. Preferably, a closing circuit is formed from a diode, a switching element, the load Lo and the inductors. Thus, even if the DC-to-AC converting circuit is disconnected from its power source, an alternating current continuously flows to the load Lo.

Inventor: BURNS GARY T
IPC: C01B33/16
Filed: 1998-02-18
Abstract: The present invention is hydrophobic silica gels having reduced surface area and a method for their preparation. The method comprises three steps, where in the first step a mixture comprising a silica hydrosol and colloidal silica is formed. In the second step the mixture is heat treated in the presence of a strong mineral acid at a pH less than about 1 to form a silica hydrogel having incorporated therein colloidal silica. In the third step the silica hydrogel is contacted with an organosilicon compound in the presence of a catalytic amount of a strong acid to effect hydrophobing of the silica hydrogel thereby forming a hydrophobic silica gel having a surface area within a range of about 100 m2/g to 450 m2/g as measured in the dry state. In a preferred method the hydrophobic silica gel is contacted with a sufficient quantity of an organic solvent immiscible with water to convert the hydrophobic silica hydrogel into a hydrophobic silica organogel.

A dose actuating mechanism for use in a dosing inhaler is also provided.
Patent CA-2291551-A1 (CA)
Inventor: KLYMYSHYN DAVID M
IPC: H04L27/20
Filed: 1999-11-26
Abstract: A phase modulator for direct wideband linear phase modulation of a microwave continuous wave carrier signal which is suitable for many analog and digital phase or frequency modulation techniques. Linear phase modulation range in excess of 360 degrees is provided as a result of linear variation in the modulating signal. A conditioned baseband modulating signal is injected into a highly linear fractional range phase shifter, operating at a subharmonic of the desired output frequency. A  nonlinear circuit is used to perform frequency and instantaneous phase multiplication, thus expanding the linear phase modulation range to greater than 360 degrees at the desired output frequency. With special conditioning of the baseband modulating signal, the phase modulator can be made frequency agile in ultra-small frequency steps, without requiring a stable, frequency agile reference signal or frequency synthesizer.

Title: Preparation of functionalised polyethers
Inventor: SHEN JIANZHONG
IPC: C08G65/10
Filed: 1998-08-24
Abstract: Unique, well defined polyethers containing both hydroxyl-functionality and unsaturation-functionality are prepared by oxyalkylating an unsaturated monomer having at least one oxyalkylatable hydrogen in the presence of an effective amount of a double metal cyanide complex catalyst, optionally, when necessary, in the presence of a free radical polymerization inhibitor. The resulting polyethers are eminently suitable for such uses as polymer polyol stabilizers or stabilizer precursors, and both in situ and ex situ impact modifiers for thermoplastics. Unique, well defined macromonomers containing hydroxyl-functionality, unsaturation-functionality, and polyoxyalkylene segments are prepared by oxyalkylating an unsaturated initiator molecule having at least one oxyalkylatable hydrogen in the presence of an effective amount of a double metal cyanide complex catalyst, optionally, when necessary, in the presence of a free radical polymerization inhibitor. The resulting unsaturated macromonomers are eminently suitable for such uses as copolymerization with ethylenically unsaturated monomers containing carboxylic acid-based groups such as acrylic acid to form effective superplasticizers and water reducers for cement and concrete applications.

Patent CA-2306265-A1 (CA)
Title: Gas scrubber
Inventor: TRIVETT GORDON S
IPC: B01D47/02
Filed: 1998-10-07
Abstract: An exhaust gas scrubber including a tank of scrubbing liquid into which a downcomer pipe(s) feeds inlet gas and fresh scrubbing liquid from a plenum. The inlet gas flows through slotted vortex generators forming fine-scale bubbles encapsulated within a scrubbing liquid. The bubbles mix and coalesce in a turbulent motion, and are then passed through another set of vortex generators which break up coalesced bubbles and form fresh fine sized bubbles, and impart an angular velocity to the mixture. Formation and coalescence of the bubbles produce gas phase to liquid phase mixing and scrubbing. Centrifugal forces created through the slotted vortex generator produce liquid circulation and recycle. The bubbly mixture then rises, bubbles coalesce and break, and the liquid scrubbing solution falls back, flowing into a relatively quiescent down flow zone around the perimeter of the scrubber outside of an overflow weir or weirs.  The outlet gas rises into a freeboard section where de-mister and heat exchanger pipes remove scrubbing vapour from the outlet gas. The scrubbing liquid flows downward into a quiescent settling tank where honeycomb vortex breakers inhibit turbulence to ensure settling of particulate into the sediment. Internal solids separation is accomplished in quiescent zones between the outer walls of the overflow dam(s) and the inner walls of the housing, and below the honeycomb vortex inhibitors. A conical bottom to the tank permits the settling sediment to be flushed out of the scrubber with the outlet scrubbing liquid. Scrubber solution liquid level is controlled by a flow and level control valving arrangement. Scrubber solution temperature is controlled by a complementary arrangement of flow controls.

Abstract: An article for use in putting on and removing a shoe. The article includes a seat assembly including a seat resting above a support. The article further includes a foot rest assembly attached to the seat assembly, and a shoe support retained by the seat assembly. The foot rest assembly includes a foot rest positionable at a selected location in front of the seat assembly and angled upwardly towards the seat assembly to present an inclined surface to a person sitting on a seat of the seat assembly. The shoe support is positionable to extend horizontally and laterally outwardly of the seat assembly at a selected location. A person may therefore sit on the seat, pick up a shoe which is resting on the shoe support, and put it on his or her foot which is resting on the foot rest. Alternatively, the person can remove a shoe from a foot resting on the foot rest and place the shoe on the shoe support.  The need to bend over to reach the ground for a shoe is eliminated through use of the article and a shoe rack. The foot rest assembly and shoe support may be retractable to improve the appearance of the article when it is not in use.
