Patent CA-2090258-A1 (CA)
Inventor: WARREN PRESTON A
IPC: A63B69/36
Filed: 1993-02-24
Abstract: ABSTRACT A golf monitoring device and method of use thereof relates to a one-piece elongated layer of rigid but slightly flexible plastic that has fold lines and can be folded into three sections.  The device has a front edge and rear edge with one straight side edge and one curved side edge.  The device fits entirely between the golfer and the ball with the golfer's feet adjacent to the straight edge and the ball adjacent to the curved edge. The ball is located on an opposite side of the device from the golfer's feet and neither the ball nor the golfer's feet are supported or located on the device.  The curved edge approximates a two-dimensional path of a golf swing.  Along the straight edge is a rear foot indicator, which is variable within a defined limit, and a front foot indicator which is fixed.  On the curved edge, there is a ball indicator which is variable.  The ball indicator is located near to the front of the device and provides for placement of the ball in a location where the ball will form an acute-angled triangle with the foot indicators.  Since the foot indicators are located along the straight edge, it is relatively easy for the golfer to square himself relative to the device.  The device has one set of indicators on each of an upper and lower surface thereof, the two sets of indicators being mirror images of one another so that the device can be used by left-handed or right-handed golfers simply by flipping it over so that an appropriate surface is up. Previous devices are too complex, too restrictive, too cumbersome or they create artificial playing conditions.

Title: Apparatus and process for the preparation of silver nitrate
Inventor: HENNENKAMP JEFFERY R
IPC: C30B7/04
Filed: 1993-02-24
Abstract: An apparatus and process are disclosed for preparing silver nitrate crystals by evaporative crystallization.  A feed silver nitrate solution is introduced into an evaporative crystallizer (10). Steam is provided to a steam jacket (30) to heat the solution in the crystallizer (10) and form a slurry comprising silver nitrate crystals.  The crystallizer (10) has an agitator (20) to mix the slurry and promote crystal growth.  Slurry density is maintained within a desired range by controlling the rate of steam flow to the steam jacket (30) via a control valve (34).  Slurry containing silver nitrate crystals is withdrawn from the crystallizer (10) and introduced to a centrifuge separator (78), for separating and drying the crystals. Liquors are recycled through a redissolver (82) to the crystallizer.  Separated, dried crystals are fed through a compactor (100) to produce a compacted product.

Abstract: The invention relates to a process for disposing of bromofluorocarbons or bromochlorofluorocarbons (termed halons below) or mixtures thereof with fluorocarbons (FCs) or chlorofluorocarbons (CFCs).        The invention comprises thermally cleaving halons or halon-containing FCs or halon-containing CFCs, for example by means of an oxyhydrogen flame, cooling the resulting gas stream, oxidizing the hydrogen bromide formed in the cleavage to bromine by feeding excess elemental chlorine into the gas stream, absorbing the resulting HF or HCl from the gas stream with recovery of hydrofluoric acid or hydrochloric acid and finally separating elemental bromine and chlorine from each other by distillation or reducing both to give the salts.

Title: Induction heater
Inventor: GEISSLER STEVEN J
IPC: H02M7/48
Filed: 1992-08-21
Abstract: An induction heater comprises a coupled pair of inverters and an induction head for generating heat, coupled to the second inverter. The first inverter operates at a constant frequency, but the total output current is controlled through pulse width modulation.  The output current is rectified and provided as a DC input voltage, proportional to the total output current of the first inverter, to the second inverter. The second inverter operates at an adjustable frequency which is selected by the user to optimize heating. The power delivered to the induction heater is dependent on the output voltage of the second inverter, which is dependent on the input voltage to the second inverter, and the output current of the first inverter.

Inventor: KREIDER EDWARD W
IPC: F22B37/24
Filed: 1993-04-02
Abstract: A buckstay system for a membraned-tube wall having a first wall section which meets a second wall section at an angle to form a corner, utilizes the natural load carrying ability of membraned tube wall construction to simplify or eliminate structural components previously utilized at such locations. Some embodiments use the membraned-tube wall corner configuration alone, or in combination with corner reinforcing plates and/or stiffening members to distribute combustion gas pressure loads to adjacent membrane-wall panels. Other aspects provide reinforcement only to accommodate transient overpressure conditions.

Abstract: Précis Les containers à déchets ou à contenu maladorant sont soit laissés à l'air libreà l'extérieur ou soit entreposés dans un local réfrigéré pour ralentir la propagation des odeurs du contenu. La présente invention sert à éliminer les odeurs produites par les container à déchets. De fait en raccordant un système de ventilation approprié muni d'un caisson de filtres au charbon relié directement au container à déchets pour maintenir ce dernier en pression négative, on obtient alors un container à déchets qui ne provoque plus d'odeurs malodorantes.
Patent CA-2098469-A1 (CA)
Title: Device for controlling an asynchronous motor
Inventor: JEANNERET RENE
IPC: H02P27/06
Filed: 1993-06-15
Abstract: The present invention concerns a control device for an asynchronous motor, notably intended for the drive system of an electric vehicle. This control device comprises electric supply means able to produce an AC supply voltage whose frequency (FAL) and amplitude (UAL) may be adjusted independently of one another. For a given frequency of the supply voltage, the amplitude of this voltage is able to vary between a minimum value and a maximum value, the difference between the frequency of rotation of the turning magnetic field in the vicinity of the motor and the frequency of rotation of the rotor being maintained substantially constant as long as the amplitude of the supply voltage is less than said maximum value. Once this maximum value has been reached, the torque on the shaft of motor is increased by an increase of the slip.
Patent CA-2100969-A1 (CA)
Inventor: HAMMOND MARK S
IPC: G06Q10/00
Filed: 1992-01-31
Abstract: 2100969 9214212 PCTABS00014 A system is disclosed for funding future losses incurred by an insurance carrier on active workers' compensation insurance claims. Forecasting accuracy is improved by generation of statistical models (22) for the various claim types presented. Each model is applied to active claims (30) to obtain cost and duration predictions (46). Total cost predictions are proportioned among various cost categories to more accurately reflect acaudal and predicted claim costs. A reserve amount is calculated based on predicted cost less any amount paid to date. Balancing of the computed reserve amounts is achieved by use of a hypothetical fund for transferring reserve money from overpredicted claims to the reserves of underpredicted claims. A total reserve amount is calculated for each claim, and an aggregate reserve amount is calculated for all active claims.

Abstract: ABSTRACT       The use of surfactants in miscible and near-miscible floods for enhanced oil recovery is disclosed,  wherein the selection of the surfactant used is tailored to accommodate one of two types of gas sweep problems.  The first type is conventionally caused by viscous fingering,    gravity    override,    and    moderate    permeability stratification, and the second type is conventionally known caused by highly conductive thief zones.  The surfactants are generally certain alkyl ethoxy and/or propoxy sulfonates or sulfates, or alpha-olefin sulfonates.

Title: Method and device for triggering of x-ray image sensor
Inventor: NELVIG PER
IPC: H05G1/60
Filed: 1992-06-01
Abstract: The present invention demonstrates a method and a device in the technique of using an image sensing member, preferably a CCD ("Charge Couple Device") cell instead of a film sensitive to X-ray radiation. The method and the device is applicable to a general X-ray arrangement without any necessary direct connection between the image sensing member and the X-ray arrangement. A number of detector points for X-ray radiation are provided at or in the CCD cell. The method and device of the present invention result in minimizing of the radiation dose to exactly that which is needed for exact imaging exposure of an image, and therefore more images may be obtained within the same total normal radiation dose.
