Patent CA-2177943-A1 (CA)
Inventor: GANNAWAY EDWIN L
IPC: F24H4/04
Filed: 1996-05-31
Abstract: A water heater using the heat pump principle includes a hermetic compressor mounted within a well defined within a water tank. The outlet fitting of the compressor is connected to a condensing tube within the tank that heats the water. The compressor includes a radially outwardly projecting flange that is supported on a support surface on the upper header of the water tank through a resilient pad. The pad includes ribs, dimples, or other projections to partially support the flange away from the surface of the pad and/or to support the pad off of the support surface on the header, to thereby vent the volume defined between the compressor and the well.

Title: Method and system for skin effect correction in a multiple transmit frequency induction logging system
Inventor: MITCHELL WILLIAM K
IPC: G01V3/28
Filed: 1996-06-27
Abstract: An induction logging tool is disclosed for utilization in conjunction with surface electronic equipment for measuring a characteristic of subsurface formations. A transmit signal which is comprised of a repetitive sequential series of at least three transmit frequencies is generated by coupling an oscillator to a transmitter coil and a plurality of selectable tuning capacitors. A signal characteristic of the response of the formation to this transmit signal is detected at a receiver coil array and two phase sensitive detectors are then utilized to generate output signals indicative of the magnitude of the X and R components of the formation signal which is in phase with a reference phase signal. The output signal of each phase sensitive detector is then utilized to accurately determine the X and R component of the receiver coil signal for each frequency by nulling the output of the phase sensitive detector utilizing a closed loop conversion circuit which eliminates errors due to phase and gain variations. The X and R signals from two or more frequencies are then utilized to correct for skin effect in both magnitude and spatial response.

Patent CA-2188050-A1 (CA)
Title: Data embedding
Inventor: HANDEL THEODORE G
IPC: H04N7/08
Filed: 1996-02-22
Abstract: A method of embedding auxiliary information into a set of host data, such as a photograph, television signal, facsimile transmission, or identification card. All such host data contain intrinsic noise, allowing pixels in the host data which are nearly identical and which have values differing by less than the noise value to be manipulated and replaced with auxiliary data. As the embedding method does not change the elemental values of the host data, the auxiliary data do not noticeably affect the appearance or interpretation of the host data. By a substantially reverse process, the embedded auxiliary data can be retrieved easily by an authorized user.
