Title: Lattice blade
Inventor: MORRIS CARL
IPC: B26D1/00
Filed: 1989-05-29
Granted: 1994-03-22
Abstract: ABSTRACT OF THE DISCLOSURE A integrally-formed knife for producing thick waffle-cut and lattice-cut potato slices has a blade and a shank extending rearwardly from the blade. The blade has opposing inclined surfaces which meet at a forward blade portion to define a thin corrugated cutting edge. Each blade surface has undulations defining a set of alternating grooves and ridges each extending rearwardly from the cutting edge and terminating at the shank. The relative inclination of the blade surfaces results in progressively greater blade thickness at a rear blade portion such that the blade is relatively rigid and self-supporting. This eliminates use of clamps on the opposing blade faces and consequent interference by clamps with slicing. The sets of grooves diverge relative to one another adjacent the rear blade portion where their bottoms are spaced in a direction transverse to the blade surfaces. The shank is unobtrusively connected to the relatively wide rear blade portion between the bottoms of rearward ends of the grooves. The shank has apertured mounting tabs extending laterally beyond either side of the blade to permit mounting in a conventional rotary-type potato slicer. -14-

Abstract: Provided is a process for the preparation of chlorine dioxide.  The process comprises separately feeding compounds, which when reacted together yield chlorine dioxide, into a diluting water stream.  The compounds react to thereby form chlorine dioxide.  Shutoff valves are provided in the feed lines of the compounds, which shutoff valves are in cooperation with a supply monitoring system and a pH meter.  The supply monitoring system monitors the feed lines of the compounds and the water stream.  When the monitoring system detects a loss in the supply of the water or one of the compounds, shutoff valves are closed to restrict any further flow of the compounds through the feed lines.  The pH meter is located downstream of the reaction and monitors the pH of the chlorine dioxide solution formed by the reaction.  When the pH is detected to be outside of a particular range, the shutoff valves are closed to restrict any further flow of the compounds through the feed lines.  This system for generating chlorine dioxide has the advantages of allowing one to prepare chlorine dioxide of optimal quality on a consistent basis.  Moreover, the system provides for immediate safeguards in the event of an emergency.  Such safeguards are extremely important when dealing with hazardous chemicals, such as those used in the generation of chlorine dioxide.

Date Apr. 30, 1981.A method for producing decorative glass objects in which the decoration is created by blisters formed by air bubbles within solid glass and/or by a pattern on the outer surface of the glass. When producing glass objects provided with air bubbles by means of known methods the bubbles remain on the surface of the objects which then easily break. In addition, the bubbles are formed at random, which may make them appear as dim impurities. When, in accordance with the invention, molten glass is poured from above in the shape of a band into a hot mould, the molten glass is spread into the mould in layers between which microscopic air bubbles remain. As the glass surface cools, the air enclosed within the bubbles expands in the molten glass which, while cooling, leaves the bubbles as clear pearls inside the glass. As the molten glass is spread in layers towards the wall of the mould, a pattern is formed as the glass surface cools.
