Patent CA-1306007-C (CA)
Title: Power regulator for a contactless credit card system
Inventor: BILLINGS ROBERT L
IPC: H02M11/00
Filed: 1987-04-13
Granted: 1992-08-04
Abstract: Abstract:               1 A power transfer arrangement provides regulated power transfer from a station to a contactless portable data card without the need for regulation circuitry on the card itself.  The station includes a primary coil for magnetically coupling power to a secondary coil, located on the card, when the data card is brought into close association with the station.  The arrangement includes a microprocessor, a power amplifier including the primary coil, a variable voltage source and apparatus for measuring current flow in the primary coil.  When the portable data card is not in close association with the station, the microprocessor causes the variable voltage source to provide a sequence of stepped voltages.  Quiescent current flow is measured at each step and stored in memory. When the portable data card is brought into close association with the station, the microprocessor causes the variable voltage source to provide a sequence of stepped voltages.  Active current flow is measured at each step and stored in memory. Power delivered to the data card is calculated as the difference between active and quiescent currents multiplied by the magnitude of the variable voltage source.  The sequence of active current measurements continues until the calculated value of power delivered to the data card exceeds a predetermined threshold power, at which time the data card is receiving a precise, predetermined amount of power.

Title: Acylation of aromatics
Inventor: HENKELMANN JOCHEM
IPC: C07C45/46
Filed: 1987-05-28
Granted: 1992-07-28
Abstract: ABSTRACT OF THE DISCLOSURE:           Aromatics are acylated by a Friedel-Crafts method using AlCl3 or AlBr3 as a catalyst.   The acylation is carried out in the additionnal presence of metalalkyls or metalalkyl halides of metals or semimetals of main groups two to five and/or of metals of subgroups two or four of the Periodic Table.  The addition of organometallic compounds results in binding of the hydrogen chloride present or formed in the reaction mixture,  and causes suppression of side reactions by interaction of AlCl3 and hydrogen chloride, thereby giving aromatic ketones in high yield.

Granted: 1991-07-16
Abstract: AUTOMATED INTERFACE TO PROJECT MANAGEMENT TOOL    ABSTRACT OF THE DISCLOSURE      A method for the automatic interfacing of a conceptual design tool with a project management tool  is  disclosed.    The  conceptual  design  tool provides  for  the early manufacturing  involvement information needed to aid and  improve  the  total design and manufacturing effort to produce a final product.   The conceptual design tool  is used to build and modify a product structure.   Using the conceptual design tool, a user inputs manufacturing details by item in the product structure.  When the user invokes the project mangement tool interface, the system prompts the user to select items of the product structure which are critical.   The system then orders the selected items according to lead times from manufacturing detail data gathered by the conceptual design tool.   The ordered data is then formatted in a file of the project management tool.  The formatted file is then imported into the project  management  tool.    In  addition,  data modified by the project management tool can later be reformatted for export to the conceptual design tool to allow the design process to continue with updated project data.

Abstract: An auxiliary air amount control system for an internal combustion engine has an auxiliary air passage bypassing a throttle valve arranged within the intake pipe of the engine, and a control valve controlling the amount of auxiliary air supplied to the engine through the auxiliary air passage by varying the opening of the passage.  The opening of the control valve is set in response to the opening of the throttle valve, and is decreased progressively from the set value as an initial value when the engine is in a predetermined decelerating condition.  The set control valve opening is varied to a larger value as the reduction ratio assumed by a transmission connected to the engine is larger.  The minimum value of the throttle valve opening at which the control valve opening can be set to a value larger than zero is varied to a smaller value as the reduction ratio is larger.  The rate at which the control valve opening is progressively decreased is varied to a smaller value as the reduction ratio is larger.
