Patent CA-2165710-A1 (CA)
Inventor: BENTLEY JON LOUIS
IPC: H04M1/27485
Filed: 1995-12-20
Abstract: An arrangement provides an interface between a telephone device and a personal computer in such a manner that enhanced capability for both the telephone device and the computer in processing information in an analog telephone environment is provided. The telephone device attaches to an analog telephone line and advantageously operates either as a stand-alone device when the computer is powered-off or in tandem with the computer when the computer is powered-on. A user is able to access any of the available telephony features from the telephone device at all times and from the computer when it is powered-on. Such available telephony features include, by way of example, Caller ID for decoding available information presented on the analog telephone line and an integrated telephone answering system, which provides for reception, transmission, and storage of voice, facsimile, and electronic mail messages.

Title: Anti-cinch automatic locking retractor with cam release
Inventor: CROOK JAMES E
IPC: B60R22/44
Filed: 1995-12-27
Abstract: An anti-cinch automatic locking retractor. A web spool is rotatably mounted between a pair of upstanding walls. The spool includes a pair of flanges each having a plurality of locking teeth with the teeth spaced apart by an included angle. A pawl is pivotally mounted to the walls and is lockingly engagable with the teeth. A cam plate mounted adjacent the spool and rotatable therewith includes a cam surface extending through an angle greater than the teeth included angle to limit cinching of the web spool as the spool rotates to and from the locking position and through the included angle. A cam release rotatably mounted to the upstanding walls limits movement of the cam plate.

IPC: H04L12/56
Filed: 1994-09-20
Abstract: An asynchronous data transfer and source traffic control system includes a bus master (100) and a plurality of bus users (112, 114, 116) coupled to a bidirectional data bus (120-128). The bus master (100) provides two clock signals (120, 122) to each bus user (112, 114, 116), a system clock (120) and a frame clock (122). The frame clock designates the start of a frame. A frame format preferably includes fifteen or sixteen system clock cycles, the first of which is designated the request field and the last of which includes a grant field. One or more other cycles may be assigned control and/or routing information and the remainder of the cycles comprise a data field of fixed length. During the request field, any number of bus users (112, 114, 116) may request access which is received by the bus master (100). During the grant field, the bus master (100) grants access to a selected bits user (112, 114, 116) for the entire data portion of the next frame. Which user (112, 114, 116) is granted access to the next frame is determined according to an arbitration algorithm in the bus master (100) which may be unknown to the bus users (112, 114, 116). The asynchronous data transfer and source traffic control system has particular application in accommodating the transfer of the contents of ATM cells used in BISDN systems.

Title: File transfer mechanism
Inventor: MCWILLIAMS GAVIN
IPC: H04L29/08
Filed: 1995-05-19
Abstract: In order to transfer a series of data files between two computers, each computer is provided with a file transfer mechanism. The file transfer mechanism is responsible for the overall control of the transfer of the series of files. Each file transfer mechanism controls the transfer of a series of files in accordance with a protocol. In this protocol, the computer receiving data files (the initiator) sends a poll request message (40) to the computer transmitting the data files (the responder). In response, the responder sends a reply message (42) to the initiator containing a list of files which are available for transfer. From this list, the initiator selects the files which it wishes to receive and then copies each file in turn. It then sends an acknowledge (48) to the responder.

Patent CA-2191169-A1 (CA)
Inventor: WHEELER ROGER D
IPC: B05B7/04
Filed: 1996-11-25
Abstract: The invention is directed to an improved pneumatic valve for use in paint spray guns of the type having a pneumatic trigger operating mode. When actuated by a trigger, the valve vents a pressurized chamber in the spray gun, causing a piston to move to open air and fluid valves for initiate spraying. The pneumatic valve is in the form of a snap in module which is easily replaced without the need to remove thespray gun from the spray booth and without the need to replace a number of smallparts. A small return spring and the pressurized air urge a valve poppet to a closed position. When the trigger is operated, the poppet is unseated to vent the pressurized chamber in the spray gun. The flow of air through the valve during painting prevents dirt and paint overspray from accumulating on the valve.

Patent CA-2197974-A1 (CA)
Inventor: HARTZEL RONALD DALE
IPC: H01H9/34
Filed: 1997-02-19
Abstract: An electrically insulated turbulator for use in an electrical device for automatically interrupting an overload current is a one-piece molded assembly with an arcuate portion arranged around a terminal screw and a downwardly turned flange for shielding the terminal from the ionized gases in the arc chute. The arcuate portion has several fins and spaced-apart planar portions, both of which are located in the path of the ionized gases. The planar portions have surfaces which cooperate with the fins to create a turbulent flow pattern to decrease the length of the gas flow, and thereby optimize the cooling effect on the gases and for directing the gas flow in a desired direction. The turbulator is preferably made of a gassing material which contributes to the deionizing of the gasses, which lessens the buildup of gas pressure. It also preferably has a blowout membrane in order to limit the back pressure in the device.

Abstract: A prediction-type medical thermometer (11) comprises a base housing (13) and an elongated probe (15) connected together by a flexible wire (16). The probe (15) includes an elongated base (21) and a special hollow probe tip (23) having a low heat capacity and which contains a thermistor (19) and a resistive heater (31) that is actuated only upon removal of the probe (15) from the base housing (13). The heater (31) regulates the temperature of the probe (15) to a value of about 93 °F. After the probe (15) is applied to the patient, a microprocessor repeatedly samples the thermistor (19) and estimates the patient's temperature based on the successive samples. For example, if a predetermined number of successive temperature estimates lie within a predetermined error range, the sampling is terminated and the most recent temperature estimate is displayed as the patient's temperature.
