Title: Heating apparatus for vehicle
Inventor: BAN TAKASHI
IPC: B60H1/08
Filed: 1998-01-05
Abstract: A heating apparatus for a vehicle includes a heat exchanger for implementing heat exchange between coolant which has cooled an engine and air directed to a vehicle interior to heat the vehicle interior. A viscous heater has a rotor and a heating chamber containing viscous fluid. The rotor rotates when being subjected to rotational power of the engine. The viscous fluid is subjected to a shear force and is heated when the rotor is subjected to the rotational power. The viscous heater heats the coolant fed to the heat exchanger as the viscous fluid in the heating chamber is heated. A clutch is operative for selectively permitting and inhibiting transmission of the rotational power from the engine to the rotor. A belt transmission device connects the engine and the clutch. A physical quantity detecting device is operative for detecting a physical quantity related to a rotational speed of the rotor. A control device is operative for controlling the clutch to inhibit the transmission of the rotational power from the engine to the rotor when the physical quantity detected by the physical quantity detecting device is equal to or less than a predetermined value.

Patent CA-2227475-A1 (CA)
Title: Removable adhesive tape with controlled sequential release
Inventor: HAMERSKI MICHAEL D
IPC: C09J7/26
Filed: 1996-07-10
Abstract: Double-sided stretchable adhe-sive tapes are described for use in conventional applications, particularly including the mounting or joining of an object to another surface. An im-provement lies within the ability to control the timing of the debonding of both surfaces so that one adhesive surface releases before the other. The earlier release can be either on the ob-ject side or the surface side, depending on the desired effect. The present in-vention is applicable to all stretchable tape constructions including the use of plastic backing materials and/or elas-tic backing materials and allows such an object to be removed without risk-ing substantial snap-back of the ad-hesive tape or catapulting of the ob-ject.   The afrmentioned advantages can be achieved by a double-sided ad-hesive tape having a stretchable back-ing layer, plastic or elastic, and having a lower-adhesion or non-adhesive por-tion of one adhesive surface, so that a corresponding greater adhesion adhe-sive portion of the other side remains more aggressively adhered to a sur-face during stretch removal while the portion of the one adhesive surface is less aggressively adhered or completely released from its surface. A non-adhesive portion may be adhesive-free, or may be an adhesive layer portion which is rendered non-adhesive. A lower-adhesion portion may comprise a low adhesion material, i.e., a weaker adhesive, or may be rendered lower in adhesion by a treatment or coating.

Abstract: Acquired hypoparathyroidism (AH) occurs frequently as a component of type I autoimmune polyglandular diseases (APS-I) or as a sporadic isolated disease in adults. Whereas autoantibodies to the parathyroid glands have been reported in AH, their very existence remains controversial. We report here the detection of autoantibodies as identified through immunoblotting using sera from AH patients. The antibodies were specific to parathyroid autoantigens obtained through differential centrifugation of fresh human hypercellular parathyroid glands, obtained shortly after their surgical removal for tertiary hyperparathyroidism in patients with renal failure. Autoantibodies were detected against several parathyroid specific proteins in the 17 AH sera tested. Twelve (70 %) reacted to a protein of 70 kDa, while 16 (94 %) reacted to a protein of 80 kDa, and 3 (18 %) reacted to a protein of 120-140 kDa, respectively. The 70 and 80 kDa proteins were localized to the cytosolic fraction of the parathyroid extract, and the 120-140 kDa protein to the membrane fraction. The autoantibodies were also detectable using a dog parathyroid gland as an antigen source. However, they could not be identified using cultured human melanocytes or in rat pituitary cells as antigen sources. Sera from 50 patients with various other autoimmune diseases as well as 22 normal controls were also tested, and none reacted with any of the above specific parathyroid proteins. It is concluded that autoantibodies to 3 major autoantigens in the human parathyroid gland extract have been detected in AH patients. Furthermore, our data indicates that the 120-140 kDa autoantigen is the calcium sensing receptor and that the reactive epitope largely resides in its extracellular domain. These data confirm the autoimmune nature of AH, and the invention provides a method for detecting AH or propensity for AH as well as a method for treating AH.

Title: Pipelined phase detector for clock recovery systems
Inventor: KWASNIEWSKI TADEUSZ
IPC: H03L7/089
Filed: 1998-03-30
Abstract: A method of phase detecting a data input NRZ signal comprises applying the input data signal to a pair of parallel channels each comprising the same phase delay, and each clocked using the same clock signal. The phase delayed input data signal is coupled to respective inputs of a pair of phase comparators. The input data signal is coupled to a further channel comprising the same phase delay, and the further channel is clocked using the same clock signal. The phase delayed input signal is passed from the further channel through a further delay which is a fraction of that same phase delay, and the further delay is clocked using the clock signal. The further delayed input data signal is applied to another input of one of the phase comparators. The input data signal is applied through another phase delay which has the fraction of the aforenoted same phase delay (but is unclocked), to another input of the other of the phase comparators. Output signals are obtained from each of the phase comparators.

Filed: 1998-04-28
Abstract: Printed electrochemical display cells are arranged in layer form with two electrode layers and an electrolyte layer occupying distinct areas of a substrate. An electrolyte layer overlaps most of one electrode layer but contacts a smaller portion of the other electrode layer, which is made of a thin film. When activated, an electrochemical reaction progressively increases the area occupied by the electrolyte layer and progressively decreases the area occupied by the thin-film electrode layer. The thin-film electrode layer recedes at a boundary in common with the electrolyte layer and provides an irreversible indication of change at a rate governed by the electrochemical reaction.

Patent CA-2239821-A1 (CA)
Inventor: HADLEY HOWARD C
IPC: F16D11/14
Filed: 1998-06-25
Abstract: A wheel motor disconnect includes a rotatable plate with sized apertures including locking detents. A depressor pin extends perpendicularly from the plate. The apertures are received over shouldered spacers or guides which are connected to the wheel hub. In the drive position, the plate is located at the outermost ends of the spacers, and the pin is offset from the spring-loaded drive shaft to allow the shaft to drivingly engage a reduction gear arrangement. To disconnect the drive, the operator urges the plate axially inwardly against the bias of the drive shaft so that the apertures slide inwardly along the spacers to move the shaft out of driving relationship with the reduction gear arrangement. The operator then rotates the plate in a first direction so smaller apertures move into the shouldered area and prevent the plate from moving axially outwardly. The locking detents prevent rotation of the plate away from the shouldered area until the operator depresses the plate slightly and rotates the plate in the direction opposite the first direction.

Title: System and method for manipulating data fields in a call structure for synchronizing billing information and retaining original calling party information
Inventor: MALIK DALE W
IPC: H04M15/00
Filed: 1998-08-05
Abstract: A system and method for synchronizing billing information and maintaining original calling party information when providing an enhanced communication service. A communication is received from a first network element and directed to a feature access code. In connection with the communication, a string of data is received containing call information for correction of parameters of a call structure. In response to receiving the communication directed to the feature access code, the string of data is manipulated within the parameters of the call structure based on instructions provided by a database, whereby original calling party information located in the call structure is retained and billing information is ultimately synchronized with an associated subscriber. Advantageously, the tasks of synchronizing billing information and maintaining call origination are accomplished by providing a standard format for processing long strings of data representing information on how a call is to be configured and by reformatting the data fields based on this information so that the final call structure resembles that of the original call structure.
