Patent CA-2125401-A1 (CA)
Inventor: KAUFMAN ROBERT J
IPC: A61K49/00
Filed: 1992-12-11
Abstract: This invention relates to compositions comprising highly fluorinated, chloro-substituted, non-cyclic organic compounds having 7 to 9 carbon atoms and to processes of using them. More particularly, this invention relates to emulsions comprising those highly fluorinated, chloro-substituted organic compounds in a sufficiently high concentration to be effective in the desired level of oxygen transport, which emulsions are capable of sterilization; have long term stability, persist for sufficiently long times in the bloodstream to deliver useful quantities of oxygen, yet be eliminated rapidly enough from the body to avoid toxicity arid retention in body parts and organs. This invention also relates to emulsions comprising non-cyclic perfluorochloroethers having 7 to 10 carbon atoms, preferably 7 to 9 carbon atoms, especially perfluoro-bis-chlorobutyl ether. These novel emulsions have various medical and oxygen transport applications, such as "artificial blood" and preserving organs.

Title: Detoxified lps-cholera toxin conjugate vaccine for prevention of cholera
Inventor: SZU SHOUSUN C
IPC: A61K47/48
Filed: 1993-01-14
Abstract: A vaccine formulation comprising conjugates of detoxified LPS  with proteins including cholera toxin (CT) is disclosed. Treatment with hydrazine (DeA-LPS) reduces the endotoxic properties of the LPS to clinically acceptable levels and results in a larger and more antigenic molecule than the saccharide produced by acid hydrolysis. The conjugates utilizing the cholera toxin of V.  cholerae) are disclosed which have low levels of pyrogen, no toxic activity upon Chinese hamster overay cells and elicit booster responses of vibriocidal and CT antibodies when injected subcutaneously as saline solutions into mice. The conjugates produced as a cholera vaccine induce the same antibodies as parenterally injected cellular vaccines but have improved safety and immunologic properties.

Patent CA-2140391-A1 (CA)
Title: Straw tip
Inventor: BARNWELL KEITH D
IPC: A47G21/18
Filed: 1995-01-17
Abstract: A straw for a drinking container that is self-ventilating and self-sealing.  The straw has two parts, a straw tip and a straw cover.  The cover is retained on the straw tip and is movable by manual pressure between a closed position and an open position.  The tip has a solid closed top and an open bottom to allow for a straw extension piece to extend into the container for drawing liquid up into the straw.  The straw is self-sealing in that a hole in the cover through which a user would suck is sized to sealingly fit the end of the tip in the closed position.  In addition, the cover and tip are sealed at the open bottom in the closed position and drainage holes in the tip allow any liquid that falls between the cover and the tip to flow back into the container.  The tip has an abutment surface around its perimeter between holes that release liquid in the user's mouth and holes that allow for air intake.  The straw is self ventilating in that when the cover, which is attached to the tip just above the abutment surface, is moved to the open position, ridges on the inner surface of the cover grasp the tip's surface at certain points so as to automatically allow air into the container to draw out liquid, while at the same time preventing air from entering the user's mouth.

IPC: A01K61/00
Filed: 1995-02-09
Abstract: This invention relates to methods of procurement and keeping of live feed for decorative animals, particularly for aquarium animals.      The principal object of the invention is development of a method of  procurement  and  keeping  of  live  feed  of  invertebrate hydrobionts distinguished by a long viability time in a closed spare, which facilitates transportation of the live feed without any additional servicing.            To achieve this objective, invertebrate hydrobionts are sorted, cleaned  and  packed  into  bags  of  10  to  100  µm  thick  food polyethylene  film;  the  bags  are  further  filled  with  liquid habitat medium and  sealed  by welding.  The ratio of  the  live weight of hydrobionts to the volume of liquid medium is taken to be 1 g of live weight per 10 ml of  liquid medium. The  liquid medium can be common tap water, natural water or distilled water. The  liquid  habitat  medium  can  be  additionally  supplied  with microbicides, antispasmodics, solutions of alcali and alcaline-earth metals, soluble salts of nickel, copper, zinc.

IPC: B66B3/00
Filed: 1995-03-14
Abstract: In a display in an elevator system, more than one floor symbol but less than all floor symbols corresponding to different floors in the elevator system are displayed at the same time. At least the floor symbol corresponding to the current position and that corresponding to the next floor in the travelling direction are displayed. The display is preferably so controlled that it scrolls the floor symbols with respect to a car symbol. When the elevator car is at a given floor, the floor symbol corresponding to that floor is under the car symbol. When the elevator car moves away from that floor, the floor symbol moves on from under the car symbol,and as the car comes to the next floor, the corresponding floor symbol comes under the car symbol.

IPC: H02P25/08
Filed: 1995-05-04
Abstract: Drive apparatus (10) for a dynamoelectric machine (M) for installation in an appliance (A) to provide a wide range of programmable features.  In the preferred embodiment, the drive apparatus includes a machine drive (12) operatively connected to the dynamoelectric machine.  The machine drive includes a microcontroller (14) having as a first and program memory (16) a ROM (read only memory) defining a processor module (13) for controlling machine operation during different appliance operating conditions, and as a second and data memory (18) an EEPROM (electrically erasable programmable read only memory) for storing machine and system operating characteristic information. Multi-position switches (SW1-SWN) are connected to the processor module.  The switch functions are determined by a program stored in the program memory as further developed by data stored in the data memory.  The switch settings, in combination with the program control, establish operating characteristics for the system.  This allows an appliance manufacturer, for example, to select one set of functions or operating characteristics for the machine, and the value of the function selected by making one switch setting, while another different set of functions or operating characteristics, and other independent function valves are provided by making a different switch setting, or by a data memory change for the selected switch setting.  The characteristics defined by the switches can be changed by changing the data in the data memory.

Patent CA-2160990-A1 (CA)
Title: Induction heating of loaded materials
Inventor: MONOVOUKAS YIANNIS
IPC: C09C3/06
Filed: 1994-03-21
Abstract: A system for employing induction heating to heat a non-magnetic, electrically non-conductive material in situ quickly, uniformly, selectively  and in a controlled fashion. Particles (4) which are essential to the improved use of induction heating for this type of application are added to the host material (6) and exposed to high frequency  alternating electromagnetic fields such as those produced in an induction coil. The particles are ferromagnetic, having high magnetic permeability  and high electrical  conductivity. . The heat-generating efficiency of these particles when exposed to alternating magnetic fields, permits a smaller volume fraction of these particles in the host material such that the desired properties of the article remain essentially unchanged. Overheating  of the article may be prevented by selecting the particle Curie point such that the particle autoregulates at a temperature about equal to the temperature to which the article is to be heated. These particles preferably have the  configuration of a flake, i.e., a thin disk-like configuration.    This configuration includes a first (x), second (y) and third (z) orthogonal dimension, wherein the first and second orthogonal dimensions (x, y) are each greater than the skin depth of the particle and are each at least about 5 times the third orthogonal dimension (z).
