Patent CA-2078372-A1 (CA)
Inventor: CONN GERARD
IPC: H04M11/00
Filed: 1992-09-16
Abstract: An agent at home (12) is enabled to receive a call from a customer (14), originally directed to a transaction-processing center (16), by first identifying, at an exchange (20) of a public switched telephone network (22), the identity of the transaction-processing center and the agent(s) designated to receive calls directed to that center. Once the agent (12) has been identified, the call is routed from a first local exchange carrier central office (18) serving the customer to a local exchange carrier central office (26) serving the agent and then to the agent across a combined voice and data line (44). Upon receipt of the call, the agent simultaneously establishes a data link with the transaction-processing center so as to complete a transaction for the customer.

Title: Electrohydraulic fluid monitor system
Inventor: WILHELM PETER L
IPC: G05B23/02
Filed: 1992-10-01
Abstract: 56,201 ABSTRACT OF THE DISCLOSURE               An electrohydraulic fluid system monitors the fluid line 1, reservoir 2, motor pumps 4 and 6, accumulators 10 and drain line 13 in an electrohydraulic fluid system. The electrohydraulic fluid monitor system includes sensors 14-40 to detect temperature, pressure, fluid level and motor pump current in the electrohydraulic fluid system.  Signals from these sensors are converted 54 by an analog to digital convertor into digital signals read by a processor unit 58 and stored by the processor unit as data for diagnostic analysis.  In one embodiment of the present invention, the processor unit 58 stores the information and compares the information to predetermined threshold amounts or to previous values and outputs a malfunction indication to a status display, responsive to results of these comparisons, which indicates the presence or nonpresence of a malfunction in the electrohydraulic fluid system.  In another embodiment of the present invention, the microprocessor outputs the information to an artificial intelligence system 94.  The artificial intelligence system 94 applies a set of diagnostic rules from a rule storage 96 to obtain a malfunction diagnosis or hypothesis that indicates other rules to be applied to diagnose the malfunction.  As a result, the present invention rapidly detects or diagnoses malfunctions in the electrohydraulic fluid system.

Patent CA-2104757-A1 (CA)
Title: Pressure regulator
Inventor: ALSOBROOKS DANIEL E
IPC: G05D16/06
Filed: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE           A fluid pressure regulator of compact construction including  an  improved  diaphragm-valve  assembly  interposed between a flow body and a second body cap element. The flow body has an inlet and outlet passage and a valve cavity with a centrally disposed ported valve insert to allow the regulated passage of fluid.  Mounted to the flow body, the cap element confines a diaphragm of the diaphragm-valve assembly and houses an adjustable coil-spring biased against the assembly.  The diaphragm-valve assembly  includes  a  ring-shaped  diaphragm element interlocated between a circular element central to the diaphragm and a diaphragm compression limiting clamp plate ring. The circular element has a central recess over the valve insert which houses a spring-backed self-aligning ball valve element having a flat chordal surface adjacent the insert.  A convolute in the diaphragm element provides a more consistent effective area in relation to the valve stroke during operation improving pressure regulation and reducing stretching of the diaphragm preventing tearing, rupture or undesirable hysteresis.

Abstract: HIGH DENSITY INTERCONNECT APPARATUS      FOR AN INK JET PRINTHEAD            ABSTRACT OF THE DISCLOSURE    The body of a piezoelectrically operable ink jet printhead is mounted in an upper side surface groove formed in a mounting plate member.   A rear bottom section of the printhead body has an exposed top side surface portion which is flush with the top side of the mounting plate member and terminates forwardly of its rear end.  A high density parallel array of mutually spaced linear conductive traces is formed on this exposed top side surface portion of the printhead body, these  traces  being  used  to  transmit  electrical operating signals from a separate electronic driver to piezoelectrically drivable channel sidewall sections within the interior of the printhead body.  A multi-tiered printed circuit board secured to the top side of the mounting plate member  is used to connect  the printhead to the electronic driver.  The circuit board has a series of linear traces formed on its bottom side which register with and are soldered to the closely spaced printhead body traces, a spaced series of lower density spacing contact pads formed on its top side and releasably  engageable  with  correspondingly  spaced contact pads on the electronic driver, and internal crossover circuitry that operatively connects the high density underside linear traces of the circuit board to its lower density top side contact pads.

Title: Organic Pesticide
Inventor: WILSON WALTER R
IPC: C05G3/60
Filed: 1993-06-23
Abstract: This invention relates to a capsaicin-based, refined wax based pesticide which is, environmentally safe pesticide. The pesticide is coupled with a naturally-produced central nervous system stimulant and other naturally-produced irritants, antioxidants; insect repellents, scents, and soil nutrients. Through the synergy between the physical contraction of the wax base, containing capsaicin, as it dehydrates coupled with the higher vapor pressure (volatility) of the scent package, leads to a natural migration of the scent package to the surface of the waxy base thereby maintaining effectiveness for a longer period of time with a decreased frequency of application.
