Patent CA-2070458-A1 (CA)
Title: Process for electroplating
Inventor: GESTAUT LAWRENCE J
IPC: C25D21/18
Filed: 1992-06-04
Abstract: PROCESS FOR ELECTROPLATING                          Abstract In the electroplating of certain metals, such as zinc, a metal build-up in the electroplating bath occurs due to a higher anode efficiency than cathode efficiency, in the cell, and also due to chemical dissolution of the anode in the electroplating bath.  An electrowinning cell is provided to remove metal from the electroplating bath.  The electrowinning cell is operated with a current sufficient to remove metal from the bath substantially equal to that chemically dissolved into the bath as well as the build-up due to the difference in the anodic and cathodic efficiencies.

Title: Hot water tank energy controller
Inventor: HEIDARY ANWAR
IPC: F24H9/20
Filed: 1992-06-09
Abstract: Form 24 (ss 21. 31. 34 and 142) ABSTRACT  The idea of saving energy by turning off electric or gas water heaters during low- or no-demand periods is not new. However, the concept of automatically controlling the times on a fixed schedule is revolutionary. The new invention, Energy Saving Device, is a computerized hot-water tank energy-use manager that can enable users to save a significant amount of money on their monthly water heating bills through efficient and comprehensive control of the heating unit.    Energy  Saving  Device  is  a  programmable,  computer-controlled device that controls water heater duty cycles over a period of hours, days and weeks. A control panel is provided for the user to change the shut-down schedule, manually over-ride the system and monitor  current  system settings.  The  device  works  with  both electric and gas water heaters. An additional solenoid controlled valve is required for gas units.

Title: Method and system for asepticizing contact lenses and storing device
Inventor: BARON NEVILLE A
IPC: G02C13/00
Filed: 1991-01-11
Abstract: Light-transmitting contact lenses (14) of Polymethylacrylate, Gas Permeable or Hydrogel materials may be immersed in an aqueous liquid medium (16) contained in a storing and processing device (10), all of which are substantially transparent to the ultraviolet radiation spectrum. The lenses (14), liquid medium (16) and storing device (10) are all irradiated with ultraviolet radiation in a preselected frequency range, while simultaneously being subjected to ultrasonic frequency vibrations to thereby cause asepticization of lenses (14), liquid medium (16) and storing device (10).  The ultraviolet irradiation and ultrasonic vibrations are insufficient to cause detrimental molecular modification to the lenses (14) or storing device (10), but does cause the formation of oxidation free radicals in the liquid medium (16). The unique combination of ultraviolet irradiation and ultrasonic vibration in the presence of the liquid medium (16) containing oxidation free radicals cause rapid destruction of all microorganisms associated with the lenses (14), liquid medium (16) and storing device (10).

IPC: B03C3/00
Filed: 1992-01-10
Abstract: A method and apparatus for efficient removal of particulates from a gas is described which incorporates a barrier filter (44)  (e.g. baghouse) internally of an electrostatic precipitator (34).  An alternative embodiment is disclosed which incorporates an electrostatic precipitator (34) and a barrier filter (44)  (i.e. baghouse) in series, with a pre-charger (40) interposed therebetween.  The series arrangement enables the barrier filter (44) to operate at significantly higher filtration velocities than normal 4.06-20.32 cm/s (8-40 ft/min) versus 0.76-2.54 cm/s (1.5-5 ft/min) and reduces the size of the barrier filter (44) significantly. The pre-charger (40) adds an additional electrostatic charge to particulates exhausted from the electrostatic precipitator (34) and replaces charge lost in lengthy and poorly insulated conduits.

Title: Existing alcohol retainer cartridge and method for using same
Inventor: KHARTCHENKO SERGUEI V
IPC: G01N33/98
Filed: 1992-11-23
Abstract: ABSTRACT   The suggested invention, presents itself as a two part device, which can be attached by friction joins, to existing reactive ampoules relating to the detection of the presence and concentration of alcohol in the human body through breath analysis. The novel effect of the invention becomes apparent in that when used in conjunction with existing devices, significant improvements in the specificity and accuracy of results are met. These are occasioned by decreasing the range of false detection of like substances, which can overlay and otherwise cause an incorrect positive results. Additionally the suggested device allows one to control the sample volume as well as the speed in which the sample is introduced to the detective reaction. Finally, the device introduces a new reagent to the process, which reacts specifically with a single by-product of existing reactions, namely acetaldehydes and provides a colourmetric response from which it is possible to determine the degree of alcohol intoxication in an accuracy heretofore only possible by blood analysis. The net result of the improvements is a significant improvement in sensitivity and specificity over methods and devices presently in use.   The time needed for use of the suggested invention, inclusive of device, reagent and method is just 1.5-2 minutes, and the accuracy and specificity correlate with such a high degree of certainty to results obtained during blood control comparisons, that this device will eliminate the need for any other device inclusive of the extant corroborative blood analysis. The more accurate results are complemented not only by cost savings to law enforcement agencies by the elimination of corroborative measures but also by the absence of any need for transportation from the road-site.

IPC: G06V30/146
Filed: 1991-05-23
Abstract: A computer system and a method for a mail sorting operation in which the computer system determines the location of the ZIP code within a digital image of an address block (20) from a piece of mail. An interstroke distance is calculated for the image and the strokes of the image are thinned (38) to enhance vertical separation between the lines of the address block. A medial axis for each line is determined and the medial axis is superimposed upon the digital image. A bleeding operation is conducted on the digital image from the medial axis at which data bits that do not connect to the medial axis are notated as punctuation and interlinear connected strokes are then divided between the two lines. The last line which is determined to be large enough to contain a ZIP code based on bounding box size is then selected. Alternate splits of words are formed and the best split is selected (50) in which the last formed group is detected to be the ZIP code.

Title: Method and apparatus for breast imaging and tumor detection using modal vibration analysis
Inventor: PARKER KEVIN J
IPC: A61B8/08
Filed: 1991-10-31
Abstract: A system for using Doppler modulation parameters for producing an estimation of the vibration amplitude of an object under investigation is disclosed in which a low frequency vibration source is used to force the oscillation of the object under investigation and a coherent or pulsed ultrasound imaging system is utilized to detect the spatial distribution of the vibration amplitude of the object in real-time. The reflected Doppler shifted waveform generated by reflecting the ultrasound waves off of the vibrating object under investigation is used to compute the vibration amplitude and frequency of the object using two alternative methods, either on a frequency domain estimator basis or on a time domain estimator basis. The system may also be utilized for breast imaging and tumor detection. By conforming the breast to a regular geometry, exciting specific vibrational eigenmodes, and analyzing the Doppler modulation parameters, the inherent shear and longitudinal wave parameters of breast tissue can be calculated. These are useful for detection of tumors and other abnormalities.
