Patent CA-2205212-C (CA)
Inventor: BEECH WALTER LEE
IPC: F04B13/02
Filed: 1997-05-12
Granted: 2004-07-13
Abstract: The present invention is directed to a method for dispensing a desired amount of liquid ("unit dose") from a stationary dispenser in a system. The method comprises: (a) opening a liquid outlet valve means to commence dispensing the unit dose; (b) opening an air inlet valve means to flow pressurizing air into the dispenser to maintain a superatmospheric pressure up to about 790 kPa; (c) receiving a first signal in a controller means, the first signal being proportional to the sensed weight of a plunger when a pre-zero reference point is sensed after a major portion of the unit dose is dispensed; (d) transmitting a first output signal from the controller means to at least one gas inlet valve means and the liquid outlet valve means to interrupt momentum of the liquid in the dispenser; (e) restoring a portion of the momentum; (f) receiving a second signal in the controller means, the second signal corresponding to the sensed weight of the plunger when a zero reference point is sensed; and thereafter (g) transmitting a second output signal to close the outlet valve means in less than one second; whereby the unit dose ~ 5 per cent is adapted to be dispensed within a predetermined portion of time, without measuring the level or the volume of liquid contained in the dispenser, or directly weighing the liquid dispensed therefrom. The method and system are particularly useful for the addition of admixtures to concrete.

Granted: 2001-06-12
Abstract: A method and apparatus for selecting a destination in a vehicle navigation system are described.  The vehicle navigation system includes a display and a selection control. A first destination is selected from a primary list of destinations in response to a selection signal generated by the selection control.  The first destination is placed on a secondary list of destinations in response to its selection. The secondary list includes previously selected destinations from the primary list.  For subsequent destination selections, the primary and secondary lists are presented on the display thereby facilitating selection of destinations from both the primary and secondary lists.  A feature by which the system may search for a destination across categories is also described.
Patent CA-2223289-C (CA)

IPC: G09B23/28
Filed: 1996-06-07
Granted: 2003-03-25
Abstract: A method and apparatus for interfacing the motion of an object (18) with a digital processing system (250) includes a sensor (14, 110) for detecting movement of the object (18) along a degree of freedom. A passive pneumatic or hydraulic damper (12, 108) is coupled to the object (18) to provide a damping resistance to the object (18) along the degree of freedom and resist a movement of the object (18). The damping resistance is provided by regulating the control of a fluid with a digital computing apparatus (52), thus providing a low-cost, low-power force-feedback interface that is safe for the user. The damper (12, 108) and sensor (14, 110) provide an electromechanical interface (10) between the object (18) and the electrical system. A gimbal or other interface mechanism can be coupled between the damper (12, 108) and the object (18). The interface is well suited for simulations or video games in which an object such as a joystick is moved and manipulated by the user.

Title: Improved contact toaster
Inventor: MARCH SCOTT P
IPC: A47J37/08
Filed: 1998-01-30
Granted: 2001-12-11
Abstract: An improved contact toaster for heating sandwich buns and other food items features a housing containing a toasting chamber with an inlet and an outlet. The toasting chamber contains a pair of conveyor belts with a heated platen positioned between them. Each conveyor belt features a platen-facing portion so that two pathways are defined. Each conveyor belt also features a heat-disitributing surface. Two auxiliary heaters are positioned so that one of each heats one of each of the platen-facing portions of the conveyor belts. One of each of a pair of tensioners engages one of each of the platen-facing portions of the conveyor belts so that each pathway tapers inward to a minimum thickness and then expands outward again. As a result, food items moving through the pathways via the conveyor belts are toasted on both surfaces and also absorb heat from both the platen and the conveyor belt surfaces in a sponge-like manner as they are compressed and released.

Abstract: To locate a defective one of filter/voltage arresters (20 1, 20 2, 20 3, 20 4,... 20n-1), each associated with a corresponding one of splice cases (18 1,18 2, 18 3, 18 4,... 18n-1) on a buried fiber-optic cable (10), an operator employs a locating apparatus (24) to detect the presence of an AM signal within a prescribed frequency range that is radiated when the filter/voltage arrester becomes defective. By determining the location along the cable where the AM signal has its greatest strength, the operator can accurately establish the location of the defective filter/voltage arrester, thereby avoiding unnecessary excavation of each splice case.

Abstract: A cooling structure around the output shaft of an L-shaped vertical gas turbine, for cooling the output shaft effectively by a natural ventilation.      A gas generator 5 is arranged horizontally whereas an output turbine 1 is arranged vertically, and a pump or the like is driven by an output shaft 3. A cylinder 20 is fitted in a space 12 between the output shaft 3 and a cylindrical easing 13 and is fixed at a cylindrical flange 20a.      Cooling air 30 is caused to flow upward from between the cylinder 20 and the output shaft 3 by the ejector effect of an exhaust gas from below a baseplate 8 and by the vacuum in the casing and then to flow downward from the upper end of the cylinder 20 between the cylinder 20 and the cylindrical casing 13, so that it flows out from the lower portion into the package. The output shaft of the L-shaped vertical type gas turbine having a compact narrow space is effectively cooled therearound by the natural ventilation without providing any fan or the like.

Abstract: Une méthode de dépistage prénatal du syndrome de Down consiste à effectuer un dosage de la gonadotrophine hyperglycosylée dans des échantillons de test biologiques tels que l'urine, le plasma ou le sérum prélevé sur une femme enceinte. La gonadotrophine hyperglycosylée comprend une population de variants constituée de la gonadotrophine chorionique, de la sous-unité  beta  libre du fragment de noyau  beta  et/ou de la sous-unité  alpha  libre de gonadotrophine chorionique, présentant des différences dans le contenu de glucides par rapport à ce que l'on a observé dans des échantillons prélevés sur des femmes enceintes porteuses de foetus normaux. L'observation qualitative ou quantitative de différences dans le contenu de glucides de la population de gonadotrophine hyperglycosylée provenant d'échantillons témoins correspondants contenant une population de gonadotrophine normale, ou l'observation directe de l'espèce de variant constaté dans le syndrome de Down, indique qu'un foetus porté par une femme présente un syndrome de Down. Les dépistages typiques consistent en des analyses de glucides, des immunodosages ou des combinaisons de ces méthodes. Certains modes de réalisation utilisent une lectine telle qu'une concanavaline A réagissant à la fraction glucidique, d'autres ont recours à des anticorps contre au moins une espèce de gonadotrophine hyperglycosylée.
