Title: Liferaft
Inventor: MARTIN MICHAEL
IPC: B63C9/06
Filed: 1998-06-04
Abstract: A liferaft has a floor (52) surrounded by one or more inflatable tubes (50, 51). Two canopies (54a, 54b) are provided, one (54a) covering one side of the floor (52) and the other (54b) covering the other side of the floor (52). When the liferaft is deployed on water, support means, which may be an inflatable column (63), erect the canopy (54a) that is above the water. The other canopy (54b) is unerected and lies in the water. The system of weights (67) and elastic ropes (66) forms the canopy in the water into stabilizing means in the form of water pockets. Similar means are provided on the deployed canopy (54a) but, when the canopy (54a) is erected, they lie flush with the canopy surface and so do not interfere with the operation of the liferaft.

Title: Use of herpes simplex virus orf p protein in repression of viral protein synthesis and related methods
Inventor: BRUNI RENATO
IPC: C12P21/08
Filed: 1997-08-28
Abstract: The present invention is directed to methods and compositions relating to the treatment of herpes simplex virus infections and the screening of compounds for activity that inhibit or promote viral latency. The previously identified ORF P gene product now has been shown to interact with certain eukaryotic splicing factors and, in a cell infected with a herpesvirus containing a derepressed ORF P gene, ORF P can limit the splicing of at least two viral products. Given this function, it now is possible to screen for inhibitors and inducers of ORF P and, further, provide methods for maintaining and preventing viral latency.

Abstract: A method and apparatus for mounting auxiliary eyeglasses on conventional eyeglasses in which magnets are attached to appendages on the auxiliary eyeglasses mating with magnets mounted on the temple extensions of conventional eyeglasses.      The magnets on the auxiliary eyeglasses are mounted in sockets formed on the appendages of the auxiliary eyeglasses such that their maximum magnetic force is oriented vertically or parallel to the plane of the conventional eyeglass frame. The appendages on the auxiliary eyeglass frame fit beneath the temple extensions on the conventional eyeglasses frame to hold the auxiliary frames in place solely by the magnetic attractive force. The orientation of the magnets is such that the maximum magnetic force resists any downward movement of the auxiliary eyeglasses on the conventional eyeglasses when installed. In a modification of the embodiment, a clip is attached to or formed on the bridge of the auxiliary eyeglasses for fitting over the bridge of the conventional eyeglasses. In yet another embodiment, clips are formed on the frame of the auxiliary lens to fit over the frame of the conventional eyeglasses. Magnets are embedded in the bridge of the auxiliary eyeglasses that mate with complementary magnets in the bridge of the conventional eyeglasses when the bridge is slid beneath the bridge of the conventional eyeglasses.

Patent CA-2274516-A1 (CA)
Inventor: KATO YOSHITERU
IPC: A61K9/20
Filed: 1998-10-07
Abstract: Emulsified powders are prepared by emulsifying an oil-soluble substance, a chemically modified starch and, if desired, a vegetable gum in water. The emulsified powders obtained according to this process show less disintegration of emulsified particles caused by compressing impact, which leads to less oil exudation. The tableted product of the emulsified powders of the oil-soluble substance is easy in handling, weighing, ingesting and others and thus can be utilized over a wide range of technical fields such as foods and drinks, medicaments or the like.

Patent CA-2278075-A1 (CA)
Inventor: SNYDER ALAN
IPC: G06F21/41
Filed: 1999-07-21
Abstract: A method and apparatus of securing access to a service manager for the administration of services residing on multiple service host computers from an administration server computer is described. A user identifier, such as a user name, and a corresponding password are provided to the service manager. The user identifier is associated with a system administrator having administrative access to the services. The service manager authenticates the user by comparing the user identifier and password against a list of user identifiers and corresponding passwords stored in a persistent memory. A list of services to which the system administrator has administrative access is derived from the data in persistent memory. When the system administrator makes a request to administer one or more services from the list of services, the administrator's access control is verified at the service host computers on which the requested services reside by examining access control data in the persistent memory.      Management files are transferred from the service host computers to the administration server computer thereby facilitating manipulation of the management files utilizing the service manager.

Patent CA-2284629-A1 (CA)
Inventor: HUEN TONY S
IPC: B66F3/30
Filed: 1998-03-16
Abstract: The invention includes a brake system for a hydraulic ram (3) or another cylinder, that can be employed as an emergency brake for a lifting elevator. When actuated, the brake arms (27) contact the ram circumferentially to slow and stop the falling ram. The brake arms are preferably lined with accretable material that frictionally engages the ram to stop the downward motion of the ram. The brake system may be actuated by the loss of hydraulic pressure, by an electronic signal from a hydraulic pressure detector, by down overspeed sensor (40) or by an uncontrolled down motion detector. According to another aspect of the present invention, a controller, which is preferably a programmed control system, compares the actual motion of the elevator as sensed by a detector to a desired motion. Under certain conditions, if the actual motion differs from the desired motion, the controller actuates the brake.

Patent CA-2292450-A1 (CA)
Inventor: OLDER WILLIAM JOSEPH
IPC: H04Q11/04
Filed: 1998-06-02
Abstract: A new asynchronous message processing system and method are provided in which a process is completely defined by a state and a type. Incoming messages received by a network node are stored in an input message queue and are handled in sequence in the order they arrive, and outgoing messages are stored in an output message queue and are transmitted in sequence in the order they are generated to a destination network node. Incoming messages addressed to a process are handled by invoking a particular message handling application code which runs to completion, and which may modify the process state. Process state modifications are atomic in the sense that they either completely happen or do not happen at all; partially implemented process state modifications are undone.
