Patent CA-2036817-A1 (CA)
Title: Method of making an excitation coil for an electrodeless high intensity discharge lamp
Inventor: FARRALL GEORGE A
IPC: H01J65/04
Filed: 1991-02-21
Abstract: An excitation coil for a high intensity discharge lamp has an optimized configuration for maximizing efficiency and minimizing output light blockage. The coil comprises a conductive surface having a shape which corresponds to rotating a bilaterally symmetrical trapezoid about a coil center line in the same plane as the trapezoid without intersecting the center line. The conductive surface is disposed on a conductive core for efficient heat removal from the coil, resulting in reduced coil losses. In one embodiment, the coil cross section is increased by adding a rectangular portion to the trapezoidal portion, thereby extending the coil outwardly from the coil center line so as to remove heat from the coil more quickly without affecting light output from the lamp. The coil is constructed by separately casting the coil turns and brazing a connecting member therebetween, and then cutting a slit in each turn so as to electrically connect them in series.

Title: Mechanism and method for accumulating and folding sheets
Inventor: MARTIN SAMUEL W
IPC: B65H29/00
Filed: 1991-03-06
Abstract: ABSTRACT OF THE DISCLOSURE      An apparatus for producing items in selected configurations and a system and method for controlling the same.  More particularly, an apparatus for producing mail pieces and a system and method for controlling it to produce mail pieces in a variety of configurations are disclosed. The apparatus includes a laser printer and folding sealing apparatus controlled by a data processor.  The folder sealer apparatus combines sheets printed by the laser printer with pre-printed sheets and envelope forms, which also may be printed by the laser printer or may be windowed envelopes, folds the sheets as necessary and folds and seals the envelope form about the folded sheets to produce a mail piece.  A user inputs a configuration for the mail piece which is translated by the data processor into a data structure and transmitted to the controller of the folder sealer apparatus.  The controller controls devices comprised in the laser printer and the folder sealer by executing state routines in accordance with the data structure to produce the mail piece in the defined configuration. Concurrently the data processor transmits text from an output file to the laser printer for printing on printed sheets and envelope forms.  The data processor also controls the laser printer to print an address for the mail piece either on an envelope form or on a printed sheet in a position where it will be visible through the envelope. Thus the apparatus is controlled to process an output file stored in the data processor into a mail run having a selected configuration.  A mechanism and method for accumulating and folding sheets is also disclosed.

Abstract: An automatic power control (APC) circuit for use with a radio telecommunication apparatus. The apparatus transmits radio frequency signals at a power level prescribed by a level control signal.          In the automatic power control circuit, transmission power level is detected from the output of a duplexer. Accordingly, even if signal loss in a filter of the duplexer varies on the frequency of signals passing therethrough, transmission power level is accurately detected and the detected level is feedbacked to an amplifier of the APC circuit.

Title: Floating roof of synthetic material for liquid storage tank
Inventor: VAN DER KUIL PIET H A
IPC: B65D88/34
Filed: 1991-03-22
Abstract: ABSTRACT            The improvement relates to a method for the installation of a floating roof structure in a closed liquid storage tank and also it relates to the tank roof structure obtained thereby. It is the purpose of the invention to compose out of a great number of interconnectable syntheitic modules or synthetic sandwich boards 3 backed up by a large number of prefabricated low frame profiles 4, an integral floating roof structure 1 of extremely lightweight construction. Furthermore it is particularly important as a feature that this floating roof structure 1, by its own rigidity and its overall strongness, can fully operate itself as a building site because of the fact that the traverse frame profiles 4 used for strengthening the roof surface structure by interconnecting sandwich modules 3 have a height of e.g. no more than 2 times the single height of a module, i.e. no more than 15 cm. The level of liquid in the storage tank is now covered to a high degree, and apparently it is now possible to suppress even the recent tolerable rate of vaporization enormously, thereby contributing much to the desired degree of environmental purity.
