Patent CA-2090794-A1 (CA)
Inventor: GROSS JAMES R
IPC: C08L5/12
Filed: 1993-03-02
Abstract: ABSTRACT OF THE DISCLOSURE            Described is a method for preparing a water-swellable, substantially water-insoluble material.  The method involves forming a first solution containing a water-soluble phycocolloid.  The first solution is then added to a second solution containing an ion capable of rendering the water-soluble phycocolloid substantially water insoluble.  The phycocolloid material is then removed from the second solution and subjected to a solvent exchange to remove water present in the phycocolloid material.  Hollow particles can be formed by including a gelation-retarding agent in the first solution.          Also described is a water-swellable, substantially water-insoluble particle defining an interior void.  The particle comprises an outer shell formed from a water-insoluble phycocolloid.  The outer shell defines an interior void which contains a phycocolloid.

Patent CA-2106715-A1 (CA)
Inventor: BUTTURINI RANDAL S
IPC: G06K7/10
Filed: 1993-09-22
Abstract: A wide bandwidth slope detector has a comparator with first and second time constant circuits coupled to first and second inputs thereof.  Where one time constant is on the order of three times the other, the comparator will change state in response to the slopes of an input analog signal coupled to the time constant circuit.  Feedback can be provided by a fixed resistor or by a tracking circuit.  A smoothing or clipping circuit can be used to pre-process the input analog signals to eliminate noise therefrom.  A bar code reading system combines first and second clipping circuits to smooth the highs and lows of the input signal, coupled to a slope detector.  The tracking circuit can be used to provide a symmetrical hysteresis characteristic.

Inventor: SCHOEN JERRY W
IPC: C21D8/12
Filed: 1993-09-30
Abstract: The present invention produces a regular grain oriented electrical steel using a single cold reduction step having excellent and highly uniform magnetic quality. The method includes the steps of providing an electrical steel band having Mn of 0.024% or less in excess of that needed to combine with S and/or Se. The band is provided with an anneal at a temperature of from 900-1125°C (1650-2050°F) for a time up to 10 minutes and slowly cooled to 480-650°C (900-1200°F) followed by rapid cooling to a temperature below 100°C (212°F). The annealed band must have a critical amount of austenite, .gamma.1150°C, of 7% or more. The annealed band is cold reduced in a single stage to the desired final thickness. The strip is decarburized and provided with an annealing separator coating on one or more surfaces of the strip. Before or during the final high temperature anneal a total S level at least 15 mg per square meter is provided. The strip is final annealed at a temperature of 1100°C or higher to effect secondary grain growth. The finished regular grain oriented electrical steel hasfar superior and more uniform magnetic quality than available from previous single stage processes and which magnetic quality is comparable to regular grain oriented electrical steels made using processes requiring two stages of cold reduction separated by an annealing step.

Title: Sanitary arrangement for cats (cat toilets)
Inventor: REINARTZ JOHANN O
IPC: A01K1/035
Filed: 1992-05-15
Abstract: Abstract The advantage of the disclosed cat toilets over commercially available cat toilets is that it is automatically cleaned and supplied with fresh cat litter after use.  Since the cat litter is conveyed in an air-tight closed drawer (6) provided with an exchangeable evacuation cassette (7), the annoyance caused by bad smell is largely excluded, not only obliging the human being but also complying with the cat's need for cleanliness.  The problem is solved in that after each use of the cat toilets, the flexible bottom (8) is drawn away underneath the fresh cat litter kept in the supply tower (9) which scrapes and cleans the flexible bottom (8), and the used cat litter falls into the drawer (6) provided with an exchangeable evacuation cassette (7).   When it moves back into its initial position, the flexible bottom (8) is supplied again with fresh cat litter by means of a dosing device (10) arranged in the supply tower (9).
