Patent CA-2001266-A1 (CA)
Title: Digital phase aligner and method for its operation
Inventor: LONG JOHN R
IPC: H03L7/00
Filed: 1989-10-23
Abstract: In methods and apparatus for aligning the phase of a local clock signal with the phase of a data signal, an incoming data signal is delayed to provide a delayed data signal and regenerated with a local clock signal to provide a regenerated data signal. A difference between the phase of the delayed data signal and the phase of the regenerated data signal is detected. The phase of the local clock signal is retarded by a predetermined fraction of a bit period if the regenerated data signal leads the delayed data signal and is advanced by the predetermined fraction of the bit period if the regenerated data signal lags the delayed data signal. The retiming, detecting, retarding and advancing steps are repeated continuously to obtain and maintain approximate alignment of the phase of the local clock signal with the phase of the delayed data signal. The methods and apparatus are useful in high speed packet switches.

Title: Oxygen sensor having a flat plate element and heater
Inventor: KER ERIC L
IPC: G01N27/406
Filed: 1989-10-31
Abstract: OXYGEN SENSOR HAVING A FLAT PLATE ELEMENT AND HEATER     Abstract of the Disclosure An oxygen sensing device is proposed which has a unique sensing element.  The sensing element is substantially flat and comprises a solid electrolyte material, preferably yttria stabilized zirconia.  The sensing element has a measuring electrode which contacts the external gas to be measured and a reference electrode which contacts a known concentration of gas.  A positive resistance heater element may also be provided on the solid electrolyte body of the sensing element.         A unique feature of the flat sensing element is that the sides of the solid electrolyte body converge at an apex located between the two ends of the body, so that the width of the body is greatest at the apex and tapers from the apex toward the two ends.  The tapers facilitate secure and rigid retention of the sensing element within a housing.  The sensing element is fixtured within the housing by packing the sensing element in a pressure media between two bushings located on either side of the apex, and crimping the two bushings.  Fixturing the solid electrolyte body within the housing in this manner advantageously results in the crimping force being distributed over the surface of the ceramic sensing element and the ceramic sensing element being held in compression.

Patent CA-2004160-A1 (CA)
Inventor: ROLAND PAUL G SR
IPC: A47J31/44
Filed: 1989-11-29
Abstract: A temperature attenuator (32, 42 or 64) is provided for spacing a container, such as a coffee container (24), from a warming hot plate (14 or 14').  The temperature attenuator has a thermally insulating spacer (34, 66 or 66') which may be secured to the container or to the hot plate by an adhesive (70), by a harness (44) or any other suitable retainer.  The spacer (34, 66 or 66') is of closed peripheral configuration, for example, it may be an O-ring or gasket ring, so that heated air is trapped in an enclosed space(s) sealed between the container bottom and the hot plate.  Hot spots which otherwise would result from direct contact of the container (24) with the hot plate (14) are thus avoided and beverages such as coffee may be heated for protracted periods without developing an acrid taste.  A method of heating the container contents includes spacing the container by means of the spacer about 1/32nd to 1/8th of an inch (about 0.8 to 3.2 mm) from the heating surface (14s) of the hot plate, and maintaining the hot plate at an elevated temperature of from about 200°F to 450°F (about 93°C to 232°C).
