Patent CA-2098023-A1 (CA)
Inventor: MACKLIN DAVID
IPC: F16N7/32
Filed: 1991-12-17
Abstract: An air/oil mixture can conveniently be used as a lubricant. To produce the lubricant, oil under pressure is supplied alternately to a pair of separate oil lines (4, 5) and at least one dual-line metering valve (8) is connected to the lines to receive oil from each line in turn and to inject a predetermined quantity of oil into a mixing zone each time the supply of oil is changed from one line to the other. Air under pressure is supplied to the mixing zone to mix with the oil injected into the zone.

Title: Process of screening plasma samples for effective antibody titers against respiratory viruses
Inventor: SIBER GEORGE R
IPC: G01N33/569
Filed: 1992-04-10
Abstract: A process for identifying plasma samples containing effective antibody titers for the treatment and/or prophylaxis of in-fections caused by a respiratory virus. The process comprises contacting a plasma sample containing antibodies against a respira-tory virus with the respiratory virus. The mixture of plasma sample and virus is then contacted with a plurality of cells. The re-maining non-neutralized virus in the sample is then determined through an immunoassay following replication of the virus in the cells. Plasma samples which, at a preselected minimum antibody titer value, prevent viral replication in the cells, are then select-ed. Plasma from which the selected samples were derived are then pooled to provide an immunoglobulin preparation having in-creased effectiveness in the prophylaxis and/or treatment of infections caused by the respiratory virus.

Title: Timer controlled cigarette dispenser
Inventor: LEVENBAUM WARREN G
IPC: A24F15/00
Filed: 1992-08-24
Abstract: A cigarette dispenser (11) useful for aiding a person to stop smoking utilizes a movable belt (23) for the controlled dispensing of cigarettes.

Title: Method for rapid prototyping of programming problems
Inventor: LEBLANC RENE
IPC: G06F11/36
Filed: 1994-04-26
Abstract: A METHOD FOR RAPID PROTOTYPING OF PROGRAMMING                   PROBLEMS                          ABSTRACT     Two major Forth extensions provide high-level sup-port for building rapid prototypes for systems.  These extensions form distinct language vocabularies available in the Forth environment.  One is a Finite State Machine Language, named FSML, and the other is an object oriented language, named 200L.  Using these extension and the in-herent expandability of the Forth language, a prototype can be rapidly created.  The modeling method requires four steps.  First, using 200L, the system is described as a set of objects.  At least one of the objects must be a controlling object and so identified.  Second, using FSML, the controlling object is described as a finite state machine.  Third, the system's operation is ex-pressed as a collection of one or more finite state ma-chines.  Each finite state machine type is defined with a unique machine type name.  Any number of instances of a finite state machine type can be dynamically created at execution time.  Fourth, communication is allowed between the finite state machines.

The user can also group a set a remote facsimile machine together so that an outgoing facsimile message can be specified as going to any one of the remotefacsimile machines in the group, and the facsimile machine will send the outgoing facsimile message to all members of the group.
Patent CA-2127364-A1 (CA)
Title: A single- or multicoloured water paint
Inventor: ROSSETTI EDOARDO
IPC: C09D5/00
Filed: 1993-01-28
Abstract: The single- or multicoloured water paint, particularly for wall coverings which simulate decorations in plasterwork or decorative materials, does not need to be applied by a skilled painter. The paint is constituted by an aqueous dispersion of agglomerations produced by reacting one or more macromolecular colloids with one or more insolubilising agents, in the presence of a water dispersion of elemental particles obtained by insolubilising a macromolecular colloid in a water dispersion of solid pigments or filler and a film forming emulsion polymer. During application, the agglomerations break up into small particles and react with each other as they break up. The paint is applied by brush, roller, spatula or even by spraying, to produce decorative effects which differ in pattern and colour shading in dependence on the tool used and the method of application.

Abstract: A cassette eject mechanism for a recording or reproducing apparatus can remove a cassette eject button from a housing and can reliably eject a tape cassette only when a tape cassette should be loaded or unloaded. A battery loading mechanism for an electronic equipment can make the loading of battery simple and reliable, and becomes easy to handle. The locking mechanism can be simplified in structure so that the number of assembly parts can considerably be reduced. Further, a mechanical chassis supporting mechanism in a recording apparatus is for use with an apparatus in which a mechanical chassis or cabinet can be reduced in thickness. According to this mechanical chassis supporting mechanism, it is possible to prevent an external stress from being applied to the mechanical chassis as a twisting deform force.

Title: Water-tight flow controller for a ship
Inventor: POLE CHARLES DOUGLAS
IPC: B63B27/22
Filed: 1995-04-18
Abstract: ABSTRACT A flow controller for the hopper of a self-unloading ship controls the flow of particulate material from the hopper.  The controller is a throat having an opening and a movable gate to open and close the opening.  The gate has a sloped central surface that blocks the opening.  When the gate is open, particulate material in the hopper flows out of the hopper through the opening and onto the central surface.  From the central surface the particulate materials flow onto the conveyor system of the self-unloading ship.  The throat has a seal surrounding the opening with a corresponding bead surrounding the central surface on the gate.  When the gate and throat are in a closed position, the gate is water-tight. When the gate is open, the seal is located away from the flow of material.
