Title: Preserved cell preparations for flow cytometry and immunology
Inventor: CALDWELL CHARLES WILLIAM
IPC: C12N5/08
Filed: 1995-04-13
Abstract: This invention discloses a population of cells which have been preserved in non-frozen hydrated form, and which have been chemically treated in a manner that renders them metabolically inert and free of proteolytic enzyme activity, but without significantly altering the cell surface proteins that are of interest in flow cytometry. The absence of alteration of the surface proteins is indicated by the ability of the surface proteins to bind to monoclonal antibodies that bind to untreated proteins of the same type, with approximately the same affinity as proteins on untreated cells. The preserved cells and their surface antigens are stable for at least a month when stored at 4°C in buffered saline solution. These cell preparations are useful as quality control (QC) reagents for processes such as calibrating and standardizing flow cytometry equipment, and for use as "unknown" test samples for QC testing programs, or as patient specimens for archival storage and subsequent retrospective analysis. This invention also discloses methods of carrying out such treatment to preserve cell populations.

Inventor: OLSEN ROBERT CHARLES
IPC: B65B17/02
Filed: 1995-08-08
Abstract: Carrier stock for beverage cans or other cans of a type having a chime at an upper end and having a frusto-conical wall below the chime is formed from a single sheet of resilient polymeric material, such as low density polyethylene, with band segments defining can-receiving apertures, with webs extending generally transversely and separating the can-receiving apertures in each longitudinal row, and with finger-gripping straps arranged in pairs and configured such that each strap of each pair extends generally transversely between two of the inner band segments and is curved inwardly toward the other strap of the same pair.  Each finger-gripping strap has two legs, each being connected not only with an inner band segment but also with a connecting web, which extends therefrom, which extends generally along an inner band segment, and which connects such leg with a separating web.  At each leg, connecting web, and inner band segment, the carrier stock may have a dividing slit or a dividing aperture.  In a package comprising the carrier and associated cans, some of the lifting forces imparted to the finger-gripping straps are distributed to the separating webs through the connecting webs, so as to reduce tendencies of the carrier to peel off the cans where the finger-gripping straps are connected.

Title: Drying apparatus having rotating vane assemblies and drying method using the same
Inventor: KANAI MASAO
IPC: F26B17/22
Filed: 1995-08-09
Abstract: Disclosed is an improvement in a drying apparatus comprising a cylindrical drying vessel, the inner wall surface of which makes up a heat-transmitting surface, a heat-generating means encircling the cylindrical drying vessel, and at least one rotating vane assembly rotatably fixed in the cylindrical drying vessel.  The rotating vane assembly has vane sections, which leave between their circumferential edges and the heat-transmitting surface of the hollow cylinder an annular space small enough to allow wet material to cross and contact the heat-transmitting surface without falling therein.  Each vane section extends obliquely upward in the direction which is opposite to the rotating direction, and the circumferential edge of each vane section extends less than 360 degrees as viewed from the top.  All vane sections when rotating bear material on their upper surfaces to raise and push material against the heat-transmitting surface under the influence of centrifugal force, thus causing it to continuously climb along the heat-transmitting surface for drying.
Patent CA-2155719-A1 (CA)
Inventor: GLATT TERRY LAURENCE
IPC: G03B15/00
Filed: 1995-08-09
Abstract: A video surveillance system for monitoring an area is made up of a stationary pilot camera for monitoring the area and one or more moveable slave cameras for monitoring at least part of the area. Each slave camera is allocated to part of the area being monitored. The pilot camera produces a signal representative of the area. The location of a moving object in the area monitored by the pilot camera is determined. A signal is produced representing the location of the object. The slave cameras track the object based on the signal representing the location of the object. The pilot camera is provided with a fisheye lens and thus has a field of view wider than that of the slave cameras. The area being monitored is divided into cartesian, polar or spherical coordinates thereby enabling a microcomputer to instruct the slave camera to follow the object. The signal representative of the area is compressed and transmitted over a communications channel for remote monitoring.

Title: Allergenic peptides from cryptomeria japonica and their uses
Inventor: SAITO SABURO
IPC: A61K38/00
Filed: 1995-09-11
Abstract: Disclosed are peptides which essentially consist of T-cell epitope(s) of cedar pollen allergens, homologous peptides thereunto,   and  immunotherapeutic  agents  containing  such peptides as an effective ingredient.   These peptides do not substantially react with immunoglobulin E antibody specific to cedar pollen allergens, and significantly more activate T-cells specific to cedar pollen allergens than a negative control when assayed by the 3H-thymidine uptake method.  Thus, the agents can effectively treat and/or the prevent cedar pollinosis without fear of causing side effects when administered to mammals including human.

Patent CA-2165068-A1 (CA)
Title: Suspension for use in electrophoretic image display systems
Inventor: SCHUBERT FREDERIC E
IPC: G02F1/167
Filed: 1994-06-21
Abstract: The invention provides a working fluid for an electrophoretic image display device (fig. 1) including a dispersion of finely divided diarylide yellow pigment particles each having a charge of a given polarity and acidic hydrogen surface sites in a suspension medium. Each of the pigment particles are transportable within the suspension medium, under the influence of an electric field, toward or away from at least one transparent plate. Adsorbed on the surface of each pigment particle is a thin layer of a charge control agent having a polyisobutylene chain having a basic anchoring group (fig. 2) which reacts with the acidic surface sites to form charge pairs therewith. The polyisobutylene chains extend from the pigment surfaces on which the charge control agent is adsorbed, thereby providing a steric barrier between pigments and preventing agglomeration. The specific gravity of the suspension medium is matched with that of the pigment particles by combining effective amounts of secondary butyl benzene and tetrachloroethylene. A blue solvent dye (fig. 3) is added to absorb substantially all light scattered by the pigments when the pigments are transported away from the transparent plate being viewed.
Patent CA-2167395-A1 (CA)
Inventor: CUSSLER EDWARD L
IPC: C07C309/67
Filed: 1994-05-19
Abstract: An osmotic device that, following the imbibement of water vapor, provides for the controlled release of a beneficial agent to an aqueous environment. The device comprises a hydrophilic formulation including a beneficial agent, and if needed, an osmagent, surrounded by a wall. The wall is formed at least in part of a semipermeable hydrophobic membrane having an average pore size between about 0.1 µm and 30 µm. The pores are substantially filled with a gas phase. The hydrophobic membrane is permeable to water in the vapor phase and the hydrophobic membrane is impermeable to an aqueous medium at a pressure less than about 100 Pa. The beneficial agent is released, for example, by osmotic pumping or osmotic bursting upon imbibement of sufficient water vapor into the device core. These devices minimize imcompatibilities between the beneficial agent and ions (such as hydrogen or hydroxyl) or other dissolved or suspended materials in the aqueous medium, since contact between the beneficial agent and the aqueous medium does not occur until after the beneficial agent is released. This results from the semipermeable membrane's selective permeability for water vapor. In addition, the high water fluxes attendant with these vapor-permeable membranes facilitate the delivery of beneficial agents having low solubilities and the delivery of high dosages of beneficial agents.

Abstract: On effectue la synthèse extensive ("amplification") d'une séquence d'acide nucléique à étudier au moyen d'une série enchaînée de réactions d'extension d'amorces à plusieurs cycles. Les amorces utilisées dans chacune des réactions d'extension d'amorce du procédé contiennent des éléments non réplicables qui stoppent la synthèse d'acide nucléique et empêchent par conséquent les molécules synthétisées de servir de matrice dans les cycles subséquents. Les molécules synthétisées s'accumulent de manière mathématiquement linéaire pendant l'extension de l'amorce et confèrent au procédé une relative insensibilité par rapport aux acides nucléiques contaminants. Plusieurs ensembles d'amorces sont utilisés afin d'assurer l'accumulation d'un grand nombre de copies de la séquence d'acide nucléique à étudier. L'invention concerne également la détection d'une séquence d'acide nucléique à étudier ainsi que des trousses de réactifs permettant d'effectuer une telle réaction.

Title: A fault tolerant queue system
Inventor: HAULIN TORD LENNART
IPC: G06F11/00
Filed: 1994-11-23
Abstract: The invention relates to a fault tolerant queue system for buffering data in a packet switch with a common buffer memory for one or more output ports from the switch, said system using a number of pointers identifying storing positions in the buffer memory.  Multiple copies of the same pointer are handled in a controlled way by using a multiple pointer list where the number of copies included in the system of respective pointers are recorded.  A maintenance function checks that the number of copies of a pointer agrees with the value recorded in the multiple pointer list for the respective pointer.  The maintenance function cyclically checks all pointers and appurtenant buffer positions, one at the time.  This is preceded by an initiation procedure during which the pointer is taken out of operation by filtering out the pointer from the flow of pointers which from output queue lists for queueing pointers in queue to the output ports of the memory are returned to the idle list, until the queue system has been emptied of each copy of the pointer in question.  Thereupon the number of returned copies of the pointer is question is compared with the value in the multiple pointer list.  The maintenance function can thereafter work in accordance with one or more operating modes for performing the cyclical control.

Title: Dynamic visual acuity training method and apparatus
Inventor: FUERST RANDALL F
IPC: A63B69/36
Filed: 1994-12-19
Abstract: An apparatus and method for improving physical coordination and ability to react to moving and stationary objects is disclosed herein. A pair of voltage controlled liquid crystal lenses are mounted in a support frame which is worn by a user in the same manner as conventional eyeglasses. The lenses can be electronically pulsed between an opaque state and a transparent state. Further, the lenses scatter background light in their opaque state rather than block the light so as to provide a generally constant level of contrast and brightness. This prevents pupil dilation changes when switching between the transparent state and the opaque state. Each lens can be made to pulse from an opaque state a transparent state and then back again, and can be controlled independently or in synchronization. In operation, the user adjusts the control unit to pulse the lenses and an appropriate response is made. As the user's proficiency increases, the user decreases the pulse rate and continues to react to the object. Reduction in pulse rate is continued until the desired level of reaction proficiency is achieved. When the apparatus is eventually removed, the user will be able to react to objects moving at higher speeds with greater proficiency. Additionally, in the case of both moving and stationary objects, the user's ability to concentrate will be increased.
