Patent CA-2022208-A1 (CA)
Title: Safe acidic hard surface cleaner
Inventor: THOMAS MICHEL
IPC: C11D3/36
Filed: 1990-07-30
Abstract: ABSTRACT OF THE DISCLOSURE:         An acidic aqueous cleaner, preferably in emulsion or microemulsion form, which is of a pH in the range of one to four and is useful for cleaning hard surfaced items, such as bathtubs, sinks, tiles and porcelains, and even some such items which are not acid resistant, such as those of a European enamel known as zirconium white enamel, comprises synthetic organic detergent such as a mixture of anionic and nonionic detergents, e.g., sodium paraffin sulfonate, higher fatty alcohol ethoxylate sulfate and higher fatty alcohol or phenol ethoxylate, organic acid, e.g., mixture of succinic, glutaric and adipic acids, phosphonic acid, e.g., aminotris-(methylenephosphonic acid) and phosphoric acid in an aqueous medium.         The acidic cleaner is useful to remove soap scum, lime scale and grease from surfaces of the mentioned items without adversely affecting such surfaces, and removals of the scum, scale and grease are easy, being effected by applying the micro-emulsion to the surface to be cleaned, followed by wiping it off.  Although the cleaned surfaces may be rinsed that is often not necessary and the surfaces will be left clean and shiny after wiping, even without rinsing, or with minimal rinsing.         In the described emulsions the organic acid components effectively remove soap scum and lime scale, the detergents remove greasy soils and promote effective contact between the acid and the surfaces to be treated, and the combination of phosphoric and phosphonic acids prevents acidic attack by the organic acid(s) on the European enamel surface being cleaned.
Patent CA-2023338-A1 (CA)
Inventor: YANAGI SHIGENORI
IPC: G11B7/095
Filed: 1990-08-15
Abstract: An optical disk device for eliminating an offset of actuator which controls a fine adjustment of a tracking control.  In the device, in an offset measuring mode, an electric drive current of the actuator is changed and the drive current is stored and held when a detection output at a neutral position in a position detector of the actuator is obtained.  Then, in a usual operation mode, the obtained offset current is constantly supplied as the drive current of the actuator, whereby a spring force is cancelled and an offset of the tracking error signal is eliminated.

Title: Precast concrete panels, support pedestals constructed therefrom and an associated method
Inventor: LARSON GREG A
IPC: E04H12/30
Filed: 1990-11-21
Abstract: PRECAST CONCRETE PANELS, SUPPORT PEDESTALS CONSTRUCTED THEREFROM         AND AN ASSOCIATED METHOD        ABSTRACT OF THE DISCLOSURE A composite elevated storage  tank  is constructed utilizing precast concrete panels for a pedestal which supports a steel  storage tank.   The precast concrete panels are poured in a controlled environment not subject to  the  difficulties  inherent  with  sitecast  concrete construction,  A simple and practical method of attaching the panels to each other as well as to the foundation and steel tank ensures the concrete pedestal behaves as a shell to sustain all loads.  This method, which uses cast in plates welded together at vertical joints and vertical aligned threaded rods for horizontal joints, serves to reduce  the  length  of  time  required  to  construct  a composite elevated tank and also reduces the construction costs.

Title: Backwash method and apparatus
Inventor: LATERRA TERRANCE
IPC: B01D29/62
Filed: 1991-03-08
Abstract: BACKWASH METHOD AND APPARATUS     ABSTRACT          A method and apparatus for cleaning filter elements that are vertically positioned within a filter vessel that has a tube sheet dividing the filter vessel into a lower filter compartment and an upper plenum compartment.  A fixed volume of backwash liquid is rapidly directed from the plenum compartment above the tube  sheet through the filter elements into the filter compartment that has been drained of liquid.  The rapid movement of the backwash liquid is a result of a pressure differential between the plenum compartment and the filter compartment.  The volume of backwash liquid is maintained above the tube sheet by a pressurized condition in the filter compartment, which volume may be changed by adjusting the pressure in the filter compartment.

Title: Binary image processing for decoding self-clocking glyph shape codes
Inventor: BLOOMBERG DAN S
IPC: G06V30/224
Filed: 1991-06-12
Abstract: Binary image processing techniques are provided for decoding bitmap image space representations of self-clocking glyph shape codes of various types (e.g., codes presented as original or degraded images, with one or a plurality of bits encoded in each glyph, while preserving the discriminability of glyphs that encode different bit values) and for tracking the number and locations of the ambiguities (sometimes referred to herein as "errors") that are encountered during the decoding of such codes.  A substantial portion of the image processing that is performed in the illustrated embodiment of this invention is carried out through the use of morphological filtering operations because of the parallelism that is offered by such operations.          Moreover, the error detection that is performed in accordance with this invention may be linked to or compared against the error statistics from one or more alternative decoding process, such as the convolution filtering process that is disclosed herein, to increase the reliability of the decoding that is obtained.
