Patent CA-2199755-A1 (CA)
Inventor: TAICHER GERSH ZVI
IPC: G01V3/32
Filed: 1997-03-12
Abstract: An electromagnetic wellbore logging tool including an elongated sonde adapted for traversing the wellbore, a source of alternating current, an antenna connected to the source of alternating current, and a receiver circuit connected to the antenna. The receiver circuit provides an output corresponding to electromagnetic signals induced in the antenna. The invention includes at least one insulating insert disposed in an annular space between the exterior of the sonde and the wall of the wellbore. The insert extends in a direction so as to segment the paths of eddy current which would otherwise flow in the annular space. In a preferred embodiment, the logging tool includes a nuclear magnetic resonance apparatus having a longitudinal dipole antenna. The insulating inserts extend along the longitudinal axis of the tool so as to segment eddy current paths perpendicular to the longitudinal axis of the tool.

Title: Self-evacuating vacuum cleaner
Inventor: BERFIELD ROBERT C
IPC: A47L11/30
Filed: 1997-07-11
Abstract: A vacuum cleaner has an electric motor driving an air impeller for creating suction and a pump which draws liquid material through an inlet tube from the bottom of a tank and expels it from the tank.      The vacuum cleaner also includes a mechanical shut-off and override assembly that automatically shuts off the motor if the liquid level in the tank gets too high. A user, however, can mechanically override this automatic shut-off in order to continue pumping liquid out of the tank. A priming apparatus is. disposed in the tank in fluid communication with the pump, and a valve is selectively actuable to establish a pressure differential across liquid in the priming apparatus to thereby prime the pump.

IPC: F01K23/10
Filed: 1998-02-24
Abstract: In a combined cycle power plant, exhaust from a high pressure turbine is branched so that part of it is supplied to a steam cooling system, and the other part of it is supplied to an inlet of a reheater of an exhaust heat recovery boiler. The exhaust supplied to the steam cooling system performs predetermined cooling and becomes heated. Then, the heated exhaust is guided from an outlet of the steam cooling system to an intermediate position of the reheater, merged with the exhaust supplied to the inlet of the reheater, and temperature-adjusted in the reheater. Then, the reheated, combined steam is supplied to a downstream turbine for heat recovery. Thus, a safe, reliable steam cooling system is achieved by effectively using a sufficient amount of high pressure turbine exhaust.

IPC: H04N19/537
Filed: 1996-10-31
Abstract: In transmission of bit plane coded (23) digitalized moving pictures, which are subject to a motion compensation (19) and an object based segmentation the bit planes are transmitted in order of decreasing significance. An incremental motion estimation (15, 17) and segmentation (11, 13) is performed in the transmitter (1) and the receiver (5) after each transmitted bit plane of a frame of the moving picture. As a result thereof the information, in particular the segmentation information, which must be transmitted is, in particular in the case of a low transmission rate, significantly reduced, due to the heavy reduction of motion parameters which must be transmitted. This method is, in particular, well suited for employment in low rate transmission systems, such as the public telephone network.

Title: Delivery system for localized administration of medicaments to the upper respiratory tract
Inventor: PAN PAULINE C
IPC: A61K31/045
Filed: 1997-01-02
Abstract: The present invention pertains to delivery systems for the localized administration of a medicament to the upper respiratory tract. The delivery system comprises:  (a) a safe and effective amount of a medicament useful for treating the upper respiratory tract; (b) an ionic polysaccharide; and (c) a cross-linking agent. The present invention provides for the controlled, in situ formation of a thin, bioadhesive film which may bind to the buccal epithelial cells which form the surface of said upper respiratory tract. Said film formation occurs when the delivery system of the present invention comprising a medicament, an ionic polysaccharide and a cross-linking agent, in a pharmaceutically acceptable carrier, is slowly ingested by dissolution through salivation of the pharmaceutically acceptable carrier. By a series of cross-linking reactions, the cross-linking agent polymerizes the ionic polysaccharide to a film in the form of aggregates, which bind to the buccal epithelial cells in the upper respiratory tract. During the in situ cross-linking reaction, the medicament becomes entrapped in the bioadhesive polymer aggregate and thereafter is gradually released, i.e., becomes available through dissolution.
