Patent CA-2149015-A1 (CA)
Inventor: POW ERIC G
IPC: H01M8/06
Filed: 1993-11-12
Abstract: A load-following vaporizer (10) converts an inlet liquid reactant stream to an outlet vapor reactant stream. The vaporizer (10) comprises a containment shell (11), a nozzle (l7) and a fin block (12).  The fin block (12) has a base in thermal contact with a heat source, preferably a thermal fluid stream. The base has a plurality of evaporative heat transfer structures (44, 46) that are spaced from and generally radiate from the nozzle outlet. Each of the evaporative heat transfer structures has two principal surfaces oriented such that the extension of each of the surfaces intersects the nozzle (17) outlet. Upon contacting the evaporative heat transfers structures, the atomized liquid reactant dispersion is vaporized to produce a vaporized reactant stream (24). The vaporizer rapidly responds to changes in the inlet liquid (22) reactant flow rate to produce a corresponding change in the output vapor flow rate by minimizing the liquid inventory within the heated environment. The load-following vaporizer is compact, light-weight and compatible with other components of an integrated fuel processing system.

Title: Process for the separation and recovery of aspergillus niger acid protease and glucoamylase
Inventor: BRUMM PHILLIP J
IPC: C12N9/62
Filed: 1995-06-19
Abstract: Aspergillus niger acid protease is prepared by treating whole glucoamylase product containing a mixture of acid protease and glucoamylase with an anion exchange medium which selectively removes acid protease from the glucoamylase, producing a glucoamylase product which is protease-free.  The acid protease is then recovered from the anion exchange medium by elution with high salt or low pH solution.
Patent CA-2155045-A1 (CA)
Title: Off axis alignment system for scanning photolithography
Inventor: ANGELEY DAVID
IPC: G03F7/20
Filed: 1995-07-31
Abstract: The invention described herein is an alignment system used in semiconductor manufacturing.  It is the core component used to align a mask containing a circuit pattern to a wafer during a scanning sequence.  The alignment system images an alignment reticle pattern onto a wafer which contains alignment marks.          During scanning, the light from the alignment reticle image is reflected and scattered by the wafer and its alignment marks.          Multiple detectors are placed at a pupil plane of the alignment system to collect the reflected and scattered light in the bright-field and dark-field regions.  The resulting signals and their analysis results in determination of accurate alignment of a wafer.  The alignment system does not use or "look through" the projection optics of the scanning photolithographic device.  The broadband spectrum used for alignment illumination cannot be used in the projection optics designed for the deep UV wavelengths without undesirable results.  The broadband spectrum illumination utilized in the alignment system results in improved detection of wafer alignment marks independent of the various process wafer structures that can be encountered.

Abstract: An automatic, virtually leak-free filling system for filling a liquid tank (1), comprises a bulk supply tarlk (3), pump means (12, 22) and a liquid line (5, 11) connected to the bulk supply tank which at its open end is provided with coupling means (9) for a manually detachable, virtually leak-free to a filling neck (25) of a liquid inlet (10) to the liquid tank (1). The system is moreover furnished with overfill protection means which automatically cut off the liquid supply to the liquid tank (1) on reaching a predetermined filling level in the liquid tank (1). According to the invention, the liquid tank (1) is furnished with a localized vapour outlet (15) which, at least during operation, connects to a vapour return line (13). The overfill protection means comprise a float valve (20) which is capable of cutting of the vapour return line (13) when said predetermined filling level is reached. The overfill protection means further comprise a vapour flow detector (16) which is interposed in the vapour return line (16) and is capable of producing an electrical output signal when any vapour in the vapour return line (13) ceases to flow. This output signal is fed to the pump means (12, 22) causing the further supply of liquid to be cut off.

Abstract: A position control circuit having a demodulator with automatic tuning capability for use in an electro-hydraulic positioning system used to position a servo device.  The position control circuit includes the demodulator, an analog to digital converter with an input voltage range, and a microcontroller.  The demodulator has a gain and is operable to convert a feedback signal from the servo device to a position signal having a lower voltage value when the servo device is at its 0% position and an upper voltage value when the servo device is at its 100% position; the lower voltage value and upper voltage values being a function of the demodulator  gain.     Upon  operator   initiation,   the microcontroller automatically calculates the largest value for the demodulator gain that results in the position signal from the demodulator having a lower voltage value within a lower voltage range and an upper voltage value within an upper voltage range, where the lower voltage range and the upper voltage range are within the input voltage range of the analog to digital converter.

Title: A method for selecting two antennas_from which to receive a communication signal
Inventor: BONTA JEFFREY D
IPC: H04B7/08
Filed: 1995-02-09
Abstract: A base site (100) employs a method and apparatus for selecting two of a plurality of antennas (101-106) from which to receive a communication signal. A first signal quality metric is measured for a communication signal received from a first antenna (102) and a second signal quality metric is measured for the communication signal received from a second antenna (103). When the first signal quality metric differs from the second signal quality metric by a threshold, a signal receiver (113) is coupled to a third antenna (e.g., 101) and a third signal quality metric is measured for the communication signal received from the third antenna (101). Based on the three signal quality metrics, a primary antenna and a secondary antenna are selected from which to receive the communication signal.

Title: Conveyor for processing equipment having gas flow compensation

Abstract: A processing apparatus, conveyor and method for processing products or materials, such as food processing equipment or methods, is configured such that the conveyor travels in a generally helical path within a processing chamber to expose products on the conveyor to a gaseous processing media such as heated or cooled air.  The conveyor includes gas flow compensation including a plurality of gas flow compensation members which partially block a portion of the surface of the conveyor, preferably toward the exterior of the conveyor in the helical path, to deflect or direct more of the gaseous food processing media away from the less densely distributed products or materials at the exterior of the conveyor caused when the conveyor follows the helical path. The processing media is thus preferably forced in the direction of the more densely distributed products toward the interior of conveyor to uniformly expose product on the conveyor to the processing media. Alternatively, the flow compensation members may be configured to direct the flow of the processing media in other predetermined paths, such as counter to the travel direction of the conveyor.
