Patent CA-2172344-C (CA)
Title: High speed, dual head, on-line winding apparatus
Inventor: KOTZUR FRANK W
IPC: D01H1/36
Filed: 1996-03-21
Granted: 1999-08-03
Abstract: A winding apparatus is disclosed for winding of filamentary material. The apparatus includes a first and second spindles. They are independently operable and rotate about parallel spaced horizontal axes. First and second mandrels are removably mounted on the respective spindles. A traverse guide is mounted to the frame of the apparatus for reciprocating movement along an axis parallel to,  and  spaced  from,  the  horizontal  axes.  The reciprocating of the traverse guide is effected in cooperation with independent rotary drives of the spindles to consecutively wind the filamentary material on the first and second mandrels. The apparatus is further equipped with transfer device movably secured to the frame and adapted to guide the filamentary material which extends from the traverse guide from a completely wound first or second mandrel to the other unwound mandrel for winding thereon. A control device governs the operation of the drives   for   independently   rotating   the   spindles,   the reciprocating means and the transfer means for successively winding the material onto one or the other mandrel in a desired universal wind. The advance in the art is in that a high speed winding apparatus is provided for automatically transferring the filament from one rotating winding diameter to another non-rotating winding diameter to enable the filament to be wound in an  essentially  non-stop  operation.  The traverse  mechanism operates  at  higher  speeds  than  that  of  the  barrel  cam configurations of known traverse mechanisms thereby improving the productivity of the operation.

Granted: 2000-05-23
Abstract: This invention is a gaming apparatus in-cluding a series of rotatable reels (23, 25, 27) having indicia on the peripheries for displaying game results. The gaming apparatus includes a number of computers (52, 54, 56) for con-trolling the various functions of the game. One of the computers (52) includes a random num-ber generator which generates a first random number that is compared to the hit frequency defined as the probability of a game being a winning game to determine whether the game played is a winner or a loser, and if the game is a losing game, the reels are stopped to display a losing combination. If the game is a winning game, a second random number is generated which is compared to the win probability set to determine the value of the win, and the reels are stopped at positions indicating a winning combination corresponding tto the value won.

Title: Heat treatment process for aluminum alloy sheet
Inventor: WHEELER MICHAEL J
IPC: C22F1/04
Filed: 1995-09-05
Granted: 2001-05-01
Abstract: A process of producing solution heat treated aluminum alloy sheet material comprises subjecting hot- or cold-rolled aluminum alloy sheet to solution heat treatment followed by quenching and, before substantial age hardening has taken place, subjecting the alloy sheet material to one or more subsequent heat treatments involving heating the material to a peak temperature in the range of 100 to 300 ~C (preferably 130-270 ~C), holding the material at the peak temperature for a period of time less than about 1 minute, and cooling the alloy from the peak temperature to a temperature of 85 ~C or less. The sheet material treated in this way can be used for automotive panels and has a good "paint bake response", i.e. an increase in yield strength from the T4 temper to the T8X temper upon painting and baking of the panels.

Filed: 1997-03-21
Granted: 2003-08-05
Abstract: A universal receiver includes a database of communication protocols which allow the receiver to configure itself for communication with the different panels. The receiver obtains certain information from the alarm panel which is initiating the communication. In the simplest form this is the DID number used by the alarm panel. The receiver uses this information to retrieve the appropriate protocol parameters stored in the database. The receiver can also add further identification codes to the address of the alarm panel for storage in a combined database serving many alarm panels. This allows convenient recording of communications received by the Security Station which serves different alarm panel systems some of which may have the same address code.

Title: Method for treating mineral material having organic carbon to facilitate recovery of a precious metal
Inventor: SIMMONS GARY L
IPC: C22B11/08
Filed: 1995-11-14
Granted: 2004-03-09
Abstract: Provided is a process for treating refractory precious metal-containing ores, particularly gold-bearing ores, to reduce the ability of organic carbon to interfere with recovery of the precious metal. The ore may also contain sulfide materials with which the gold is associated and from which the gold is difficult to separate. The ore is comminuted (104) to a size at which at least about 80 weight percent of the ore is smaller than about 40 microns in size. The comminuted ore is then slurried and subjected to pressure oxidation (108) at severe operating conditions. The treating temperature is greater than about 190 degrees C. When sulfide minerals are present, substantially all of the sulfide sulfur must first be oxidized prior to obtaining significant benefit from the treatment of the organic carbon. Greater than about 96 % of the sulfide sulfur must be oxidized. Neutralization (114) occurs after the oxidation treatment to prepare the slurry for CIP cyanidation (118) from which gold is then recovered (128).

Abstract: A method of detecting microbiological fouling in an aqueous system. The method includes determining a baseline corrosion rate. A corrosion rate is continuously monitored. A change in the corrosion rate in measured. A maximum corrosion rate is measured. A baseline fouling factor is determined by measuring and monitoring parameters of a fluid in the aqueous system. An increase in fouling factor over the baseline is determined. A change in the corrosion rate is integrated with respect to time over an interval of from a time of the determination of the baseline corrosion rate to a time that the maximum corrosion rate occurs. A change in the fouling factor is integrated with respect to time over an interval from a time of the determination of the baseline fouling factor to a time of the determination of the increase in fouling factor. The fouling factor and the corrosion rate are compared to determine if the fouling is microbiological.

Title: Compact radio frequency transmitting and receiving antenna and control device employing same
Inventor: SPIRA JOEL S
IPC: H04B1/38
Filed: 1997-02-05
Granted: 2003-09-23
Abstract: A radio frequency antenna for use with a wall-mounted transmitter and/or receiver for receiving and/or transmitting signals adapted to control a control device and/or indicate status of the control device. The antenna includes an insulating substrate sized to fit within an area defined by a faceplate sized to cover an outwardly facing opening of an electrical wallbox.  Conductors are disposed on both sides of the substrate forming a capacitive component. At least one of the conductors is adapted to radiate radio frequency energy into the environment. The one conductor is electrically coupled to the other conductor, and the one conductor has a pattern such that the conductor is absent in areas so as to provide the antenna with an inductive component. The at least one conductor further provides a connection to the transmitter and/or receiver. The antenna provides an antenna near-field which is substantially at the edges of the substrate and which provides insubstantial electromagnetic field coupling to an electronic circuit disposed adjacent the antenna connected to the antenna and further provides a radiated field substantially isotropic in the antenna far-field.
