Abstract: The present invention describes a pipe sealing compound/adjunct lubricant used to prevent gas or liquid leaks when applied to pipe threads and other connections of the same. The compound relies on silicone oil lubricant(s) and one or more friction modifier(s), viscosity builder(s) and filler material(s). The compound contains a viscoelastic liquid that does not have a curing phase and is resistant to hardening and/or drying. The compound is chemically resistant to a wide variety of liquids and gases, is food safe and can withstand extreme high or low temperatures and precipitous temperature fluctuations. The compound has been found to exhibit an inverse pressure to leak rate phenomena.

Abstract: An aqueous bubble solution includes at least one water soluble polymer, at least one surfactant, and at least one fast drying solvent or solvent blend. The water soluble polymer forms a strong and resilient bubble wall. The surfactant(s) lowers the surface tension of the solution to create a bubble blowing film. The fast evaporating solvent or solvent blend acts to harden the bubble wall by dehydration and rapid evaporation. Bubbles blown from the solution will air dry within seconds and exhibit extraordinary strength. The bubbles do not evaporate and resist breakage upon collision with a dry surface. The bubbles remain translucent and fully preserved for hours or even days while resting on a surface.

Abstract: A display device which provides an entertaining and relaxing visual display while showing the formation of a stretched and moved sheet of a viscoelastic solution. A viscoelastic solution is contained in the bottom chamber of a container and a drawing element is slowly moved into and out of the viscoelastic solution. The drawing element is held above the surface of the viscoelastic solution and a portion of viscoelastic solution which has been drawn up with a drawing element falls slowly off of the drawing element to provide an entertaining and interesting display. Preferably, the drawing element has a horizontal bar which is slowly rotated into and out of the viscoelastic solution providing an ever-changing display.

Abstract: A process and apparatus for determining the amount of contamination in the lubricant phase of a refrigeration system. The process utilizes a clear glass tube which contains an inert substance such as glass beads coated with a solvatochromic compound, preferably the solvatochromic compound is a mixture of Benzophenoxazine and Benzophenoxazone. A sample of the lubricant to be tested is passed into the glass tube and passes over the glass beads, picking up a portion of the solvatochromic compound. A white absorbent material such as sterile cellulose is positioned adjacent the coated substrate and the color reaction between the lubricant and the solvatochromic compound is clearly evident on the white absorbent material which then can be compared with a standard set of colors to determine the amount of the contamination.

Abstract: A method for determining the amount of a contaminant in a refrigerant gas under pressure and the detector tube and tube holding assembly. The method involves preparing a predetermined length of refrigerant hose and connecting a pressure gauge to an exit end of the hose. The entrance to the hose is connected to a sealed detector tube which is held in a fitting which connects to conventional refrigerant hose. This fitting is connected at its other end to a source of refrigerant gas under pressure to be tested. The gas is allowed to pass through the detector tube into the known length of empty tube until the pressure gauge reaches a predetermined value depending upon the refrigerant gas to be tested. This causes a known volume of gas to pass through the detector tube and the detector tube changes color and the distance that the color change has taken place is a measure of the contaminant. Different detector tubes are used for different contaminants.
