Patent CA-2088901-A1 (CA)
Inventor: HALL CHARLES E JR
IPC: B65D25/16
Filed: 1993-02-04
Abstract: The present invention provides an apparatus for storing and preserving food products and for selectively dispensing the food products from the apparatus, wherein the apparatus comprises a container, a flexible bag in-serted into and suspended in the interior of the contain-er, and a cover member releasably securable over a top opening of the container.  The bag is provided with a sidewall dimensioned to slide vertically through the interior of the container without the sidewall exerting a friction force against the inner surfaces of the contain-er sidewalls with the bag filled with a food product. The bag is constructed of a flexible material that en-ables a top portion of the bag sidewall to be stretched and folded back over the top opening of the container and the outer surfaces of the container sidewalls to suspend the food product container in the bag inside the contain-er interior and above the container bottom wall.  By selectively sliding the folded over portion of the bag vertically downward and upward over the exterior surface of the container sidewalls, the food product contained inside the bag and suspended in the container interior is raised up in the container to the top opening of the container and is lowered in the container toward the bottom wall of the container.

Title: Integral casted labyrinth ring for brake drum
Inventor: DEANE ALASTAIR R
IPC: F16D65/10
Filed: 1993-02-08
Abstract: ABSTRACT OF THE DISCLOSURE     A composite brake drum for motor vehicle applications incorporating an embedded annular ring insert.  The annular ring is positioned within a casting cavity to define the surfaces of a labrynth groove at the open rim of the brake drum.   The labrynth groove defines a region for a backing plate flange to define a labrynth seal to prevent entry of debris into the brake drum.   By defining the labrynth groove using an annular ring inserted within the mold, the post-casting machining requirements are significantly reduced.  Moreover, the presence of a steel ring in the rim of the brake drum provides structural benefits.          The annular ring further preferably incorporates locating means to assure accurate positioning within the casting mold cavity.

Title: Container lid
Inventor: LUBURIC FRANO
IPC: B65D43/02
Filed: 1993-05-07
Abstract: Abstract of the Disclosure:              A container lid is characterized by a tamper-evi-dencing tear-strip member having a tab that protrudes from a plane formed by adjacent portions of the lid. The tab preferably includes gripping rib members on opposing sur-faces  of the tab and is surrounded by a sufficient gap to permit the tab to be readily grasped for easier removal of the tear-strip member from the lid, prior to initial removal of the lid from the container. In container and lid embodi-ments that are substantially rectangular, the lid also preferably includes mating engagement structure between the lid and the container which is interrupted or not present at the corners of the lid. The tear-strip in this rectangular embodiment also preferably includes a widened portion at the corners, whereby the removal of the rear-strip results in a "scalloping" of the corners. These features on rectangular embodiments facilitate easier attachment and removal of the lid to and from the container, after the removal of the tear-strip.

Abstract: DISHWASHING MACHINE WITH WATER FILL CONTROL                     ABSTRACT OF THE DISCLOSURE    In order to complete a water fill phase, an electromagnetically actuated water fill valve (11) enables water from a supply source to flow into a dishwasher tank; this water being at the same time taken in by a circulation pump (3).  Both the valve and the pump are controlled by a timer switch arranged to be energized from a power supply source (4, 5) through a normally open pressure-responsive switch (14) that is arranged to close when the pressure at the delivery side of said circulation pump (3) rises beyond a pre-determined value (P2).  At the beginning of the water fill phase, the valve (11) is opened by the timer switch until the latter has been energized for a pre-determined total period of time (T) where T equals the summation of times T1 - T6.

Abstract: TITLE OF THE INVENTION          "PROCESS FOR PREPARING NOVEL HIGH SOLIDS NON-AQUEOUS POLYMER COMPOSITIONS"          ABSTRACT OF THE DISCLOSURE     The use of falling-film evaporation and a concentration means such as centrifugal separation to dehydrate and concentrate a water-in-oil polymer emulsion or suspension is disclosed.  In a preferred embodiment, a water-in-oil polymer composition containing less than about 25% active polymer solids is dehydrated in falling-film evaporator to produce an evaporator concentrate containing less than about 5.0% water.  The evaporator concentrate then flows to a separation device such as a centrifuge, wherein oil is removed to produce a composition that is substantially a polymer and emulsifying surfactant-in-oil composition containing in excess of about 60 weight % polymer solids.  The centrifuge raffinate may optionally be treated in a second separation means to capture additional polymer solids, with optional recycle of the oil-rich raffinate.  The concentrated polymer composition is preferably stabilized with a steric stabilizer to produce a free flowing liquid product.

Title: Method and system for designing a cutting tool
Inventor: WAYNE STEVEN F
IPC: G06F17/50
Filed: 1992-06-12
Abstract: A method of designing a cutting tool uses finite element numerical models (14) to predict a response of the toot during a simulated cutting operation on a workpiece, and to simulate a chip-flow phenomenon occurring during the cutting operation. The chip-flow model (14) incorporates representations of a fracture mechanism describing a chip separation phenomenon, a heat-gen-erating mechanism describing a thermal coupling phenomenon, and a shear localization mechanism describing a shearing pheno-menon wherein these phenomena occur during the cutting operation. The predicted tool response and the chip-flow simulation are evaluated by an artificial intelligence system (18) to render rule-based judgments which are embodied in recommendations for continuously modifying the models (14) and input design variables until the simulation and response converge to an optimal re-sult.

Title: Type c-like human retrovirus linked to multiple sclerosis (ms)
Inventor: SOMMERLUND METTE
IPC: C12Q1/70
Filed: 1992-10-12
Abstract: The present invention relates to a type C-like human retrovirus.  In nested PCR analysis using high stringency PCR conditions and primer pairs and probes used for HIV-I or HTLV-I detection, no genomic sequences are detectable; in immunofluorescence analysis, antibodies directed against HTLV-I antigens p19 or p24 or the retroviruses MuLV, SSV-1 (p28), FeLV or RD114 do not bind. When performed on purified retrovirus-containing material, reverse transcriptase activity is detectable. A cell culture which additionally is infected with a herpes group virus which enhances the production of the retrovirus has been deposited. Within the scope of the present invention is diagnostic agents comprising genomic fragments of the retrovirus which can be used as nucleotide probes in PCR  and diagnostic agents comprising retroviral antigens capable of binding antibodies specific for the retrovirus which can be used for the diagnosis of multiple sclerosis as well as a method for obtaining a protective immunity against multiple sclerosis comprising administering a vaccine against Epstein-Barr virus.
