Abstract: An apparatus, method, and computer-readable medium for high ping rate depth sounding. The apparatus may cause transmission of a first sonar beam having a first frequency and transmission of a second sonar beam having a second frequency with a transducer assembly. The transducer assembly maybe configured to transmit the first sonar beam and the second sonar beam into the underwater environment. The apparatus may receive sonar return data from the transducer assembly beginning either simultaneously with transmission of the first sonar beam or prior to transmission of the second sonar beam. The apparatus may further determine, based on sonar return data acquired after transmission of both the first sonar beam and the second sonar beam, that the sonar return data corresponds to the first sonar beam by determining that the sonar return data comprises the first frequency.

Abstract: This invention is a method to coat an object or non-ferrous plate with a non-porous polymeric coating that has excellent adherence to the non-ferrous substrate. The process includes the following steps: conditioning or chemically treating a non-ferrous substrate surface; heating the substrate to a temperature above 180° C. but less than the ignition temperature of the plastic coating; applying a first layer of plastic material to the heated surface, immediately applying a second plastic layer onto the first plastic layer which is maintained at a minimum temperature of 180° C.; reheating the two plastic layers at a temperature from 180-280° C., to produce a smooth non-porous surface: and allowing the substrate and plastic coating to cool.

Abstract: A device for treating anatomical parts, particularly intestinal segments, in isolation comprising an open-ended chamber, a flexible diaphragm attached to one open end containing a plurality of incisions defining an opening through which the parts to be treated can be inserted into the chamber, a drain applied to the other end including a perforate strainer, a coupling element for connecting the drain to a source of vacuum and a plurality of nozzles positioned at equal distances abut peripherally of the chamber and substantially midway between the ends of the chamber through which a treating fluid can be ejected into the chamber.

Abstract: A catheter in the form of a flexible T tube for insertion of an end thereof through a natural or incised opening in the body of sufficient length to extend from said opening and an anchoring member attached to the stem of the T tube containing openings for receiving suturing for attaching the anchoring member to the skin at the place of entry of the stem into the opening.
