Patent CA-2087821-A1 (CA)
Title: Photodetector amplitude linearity
Inventor: GANZ ALAN M
IPC: G01J1/08
Filed: 1993-01-21
Abstract: To calibrate a photodetector, a rotating disk with a slot is disposed in a light beam with decreasing speed from a defined maximum rotational speed to a defined minimum speed, while magnitudes and times of signals are read out and stored. Vernier pairs of signals occur in adjacent readout intervals, and non-vernier signals exclude the verniers. Readout times for verniers are used to estimate a preliminary function of rotations versus time. From the function are estimated an occurrence time for each pair and period of disk rotation at the time. Vernier fraction is the ratio of one signal in the pair to the sum of the pair. A time offset is the product of vernier fraction, slot fraction of the disk and the estimated period. Occurrence times corrected with the time offset are utilized to fit a corrected function of disk rotations versus time. Points of time for the non-vernier signals are determined from the corrected function, each point corresponding to disk rotations to a corresponding non-vernier signal. These points of time are employed with corresponding signals for linearly calibrating the photodetector.

Patent CA-2090653-A1 (CA)
Inventor: SLOKA ALAN
IPC: B60T17/00
Filed: 1993-03-01
Abstract: An air dryer having a turbosaver valve which prevents the supercharged air from the engine from being discharged through the air dryer.  The air dryer comprises a stepped control port bore adapted to slidably receive the turbosaver valve for selectively sealing the control port bore and the air intake bore. The turbosaver valve is intermediate the drying chamber and the purge valve so that the turbosaver valve controls not only the flow of air through the coalescing filter but also the discharge of the purge air and the contaminants.  Disposing the turbosaver valve intermediate the drying chamber and the purge valve insures that the compressed air must pass through the coalescing filter in the loading mode while permitting the purge air to by-pass the coalescing filter in the unloading mode.  In the loading mode, the compressed intake air forces the turbosaver valve to directly seal the control port bore in order to prevent the compressed air from the intake port from passing downstream of the coalescing filter and contaminating the desiccant filter.  In the unloading mode, the turbosaver valve directly seals the air intake port in response to a control signal, allowing the purge valve to be opened without purging the supercharged air from the engine to the atmosphere during the unloading cycle.  The turbosaver valve permits the purged air to bypass the coalescing filter which minimizes the back pressure in the desiccant filter to decrease the purge time of the dryer and to increase the efficiency of the air dryer.

Abstract: ABSTRACT       In the common use of a room or auditorium, when there is a press conference, with many reporter present, there is a number of microphones attached to the speakers podium, lectern, or dais.  These microphones are random in view of the speaker or his associates.  In this invention, a means is presented whereby the microphones can suitably be placed elsewhere,  without loss of sound quality,  so that the podium area is no longer obscured by the clutter of microphones.  This invention achieves this objective by reproducing the voice or other sounds from the podium,  or otherwise form the featured speaker, within an acoustically controlled enclosure which is designed specifically for the many microphones of the new media to fit within.  The enclosure may take on various shapes.  The enclosure may be specially padded to protect the microphones that are placed within it from damaging themselves or other items or microphones within the enclosure.

IPC: B09C1/06
Filed: 1991-10-31
Abstract: The portable soil remediation unit (10) includes, on a wheeled flatbed truck (18), a rotary drum (12) having a burner (14) at one end and an inlet (20) at its opposite end for flowing contaminated soil (5) in counterflow relation to the hot gases of combustion for volatilizing the contaminants. Also mounted on the vehicle is a baghouse (16). The hot remediated soil is discharged (30) into the baghouse for screw conveyance (40) along the bottom of the baghouse to a baghouse discharge. The particulate-laden gases from the drum enter the baghouse at the opposite end (32) and are separated into particles and clean exhaust gas. The hot remediated soil is in heat transfer contact (41) with the particles and the particles release residual contaminants. The particles flow to the bottom of the baghouse for combination with the remediated soil in the screw conveyor. The hot remediated soil is additionally screened (52) in the baghouse for large and small gradations, the large and small gradations, the large gradations being discharged (60) from the baghouse for reprocessing. Rocks or organic materials may be introduced into the drum to mechanically clean the drum and assist in heat transfer to the soil.

Title: Electrolytic cell and capillary gap electrode for gas-developing or gas-consuming electrolytic reactions and electrolysis process therefor
Inventor: WENSKE HANNO
IPC: C25B9/19
Filed: 1992-06-22
Abstract: The invention relates to an electrolytic cell and a capillary slit electrode for gas-developing or gas-consuming electrolytic processes and reactions, and an electrolysis process therefor.  According to the invention, the capillary slit electrode (2, 3) has conduits (10, 13, 11, 11') enabling the separate flow of reaction gas and electrolyte/permeate in the electrode. The electrode is preferably hydrophilic in a narrow internal region (10, 13) for mounting on a separator, while elsewhere (11, 11') it is hydrophobic.  Thus electrolyte/permeate penetrates only into the region of the capillary slit electrode near the separator, while the region away from the separator remains free of electrolyte/permeate, so facilitating the unimpeded flow of the reaction gas. The invention is applicable especially in electrolytic cells for chlor-alkali or hydrogen electrolysis, and in the construction of cells for the generation of electric power.

Title: Method for minimizing the effect of memory errors within a digital information storage system

IPC: G10L19/00
Filed: 1994-10-20
Abstract: METHOD FOR MINIMIZING THE EFFECT OF MEMORY ERRORS WITHIN A DIGITAL INFORMATION STORAGE SYSTEM            Abstract Of The Disclosure A method for the retrieval of digital information from a memory device wherein data representing temporally proximate samplings of a signal, or band-adjacent frequency components of a signal are stored in separate memory locations; each of these separate memory locations being subject to circuit failure independent of other such memory locations. In practicing a particular method of the invention, the effects of errors caused by memory circuit failures within the digital data system are reduced by testing for data losses upon retrieval of the information. In response to detecting a loss, data representing a signal sampling temporally proximate to the signal sampling represented by the lost data is substituted for the lost data. In yet another method of the invention, a similar testing/substitution scheme is employed to reduce the effects of memory circuit failure errors. However, in response to detecting a data loss, data representing a frequency component adjacent to the band of the frequency component represented by the lost data is substituted for the lost data.

Title: Method for saving and restoring the state of a cpu executing code in protected mode
Inventor: COMBS JAMES L
IPC: G06F9/445
Filed: 1994-03-28
Abstract: ABSTRACT A method of saving and restoring the state of a CPU operating code in protected mode on a computer system.  The save method makes use of BIOS operating in shadow RAM located in a region where linear addresses equal physical addresses while saving the state of the CPU.  The registers that cannot be directly saved to memory are determined by searching the system memory for  data  structures  that  correspond  to  the  particular register. The restore method uses dummy page tables that point to the shadowed BIOS to allow the CPU to reenter protected mode without generating a protection fault.
