Title: Multiple product dispensing system including dispenser for forming use solution from solid chemical compositions
Inventor: MCCALL JOHN E
IPC: B08B3/02
Filed: 1995-11-20
Abstract: A multiple product dispensing system (100) includes a plurality of use solution dispensers (10a, 10b, 10c) and a controller (110) for selecting one of the dispensers (10a, 10b, 10c) according to a preset regimen, e.g., selecting different dispensers on different days of the week. Each dispenser (10a, 10b, 10c) dispenses a controlled concentration of use solution using a diluent delivery apparatus (13) that delivers a diluent to form a liquid concentrate from a solid chemical composition (22), and to form make-up diluent for diluting the liquid concentrate and forming a use solution of controlled concentration. A foam reducer (24) reduces the kinetic energy of the make-up diluent prior to mixing with the liquid concentrate to reduce foaming. An unskilled operator may operate the dispensing system (100) to dispense a use solution of carefully controlled concentration, and the controller (110) will automatically select the proper dispenser according to the preset regimen, without any additional input on the part of the operator. Therefore, the likelihood of operator error occurring is greatly reduced by the automatic selection of the proper dispenser (10a, 10b, 10c) and the control over use solution concentration.

Patent CA-2225063-A1 (CA)
Title: Pulsed plate plasma implantation system
Inventor: DENHOLM A STUART
IPC: C23C14/48
Filed: 1998-01-27
Abstract: Method and apparatus for treating a workpiece implantation surface by causing ions to impact the workpiece implantation surface.  An implantation chamber defines a chamber interior into which one or more workpieces can be inserted.  A support positions one or more workpieces within an interior region of the implantation chamber so that implantation surfaces of the workpieces are facing the interior region.  A dopant material in the form of a gas is injected into the implantation chamber to cause the gas to occupy a region of the implantation chamber in close proximity to the one or more workpieces.  A plasma of implantation material is created within the interior region of the implantation chamber.  First and second conductive electrodes positioned within the implantation chamber include conductive surfaces in proximity to the chamber interior occupied by the one or more workpieces.  A voltage source outside the chamber relatively biases the first and second conductive electrodes. A control circuit utilizes the voltage source for repeatedly relatively biasing the first and second conductive electrodes to energize the electrodes with a sequence of pulses that both ionize the gas molecules injected into the chamber and accelerate the ionized gas molecules toward the implantation surfaces of the one or more workpieces.
Patent CA-2226922-A1 (CA)
Title: Burst mode preamble
Inventor: EBRINGER LAWRENCE
IPC: H04L27/00
Filed: 1996-10-11
Abstract: In a burst mode communications system (figs. 1 and 2), bursts of information with a known preamble (402), fig. 4 are transmitted from a burst mode transmitter and are received by a burst mode receiver which uses the preamble to determine the presence of a burst and to determine the correct carrier frequency, carrier phase, symbol clock frequency and symbol clock phase in order to correctly recover the symbols transmitted, and thus the information contained within the burst. The present invention involves a method of burst transmission using a preamble (402) which contains an initial pulse (420) and a Barker sequence (440) following the initial pulse separated by a dead time (430) period equal to the transmission time of at least one symbol. The preamble can be transmitted on orthogonal carriers (fig. 5) and the order to the Barker sequence (440) can be reversed and multiplied by minus one on one of the carrier to reduce the probability that noise events on both carriers make the Barker sequence less detectable on each channel.
