Abstract: Chromic acid and inexpensive, coarse grained Cr.sub.2 O.sub.3 are dissolved in water prior to adding more costly fine grained Cr.sub.2 O.sub.3 to produce chrome pastes which are more economical than pastes prepared by prior art techniques employing only fine grained Cr.sub.2 O.sub.3. The pastes are equivalent to prior art pastes when reacted to form chromium dioxide.

A fluid passageway extends from the inside of the bundle carrier through the pivot joint and extends to the distal end of the instrument support leg. A cleanout passageway extends from the fluid passageway to the exterior of the bundle carrier.

Abstract: A device for treating aqueous solutions with magnetic lines of force includes a pipe through which the solution passes. An electromagnetic coil surrounds the pipe and a core consisting of endwise connected alternating short sections of magnetic and non-magnetic material is disposed coaxially with and spaced from the pipe. Located between the pipe and the core is a helical baffle. A housing is spaced from and surrounds the coil. Air circulation vents are located at the upper and lower ends of the housing. Annular cooling fins extend outwardly through the coil with their outer peripheries terminating in the gap between the coil and the housing. A plurality of apertures are formed in the exposed outer portions of each cooling fin with the apertures of one fin being staggered relative to the apertures of the adjacent fins.

Abstract: Mounting for ignition module in which a ferromagnetic flux carrying core includes a plurality of spaced, parallel leg portions. The ignition coil module has a generally central opening which is adapted to receive one of the core legs. A tapered slot is formed on one side of said coil module and is adapted to receive a correspondingly tapered bar portion of a synthetic plastic retainer. The retainer is an integral, thermoplastic block with a channel on the side opposite the tapered bar portion adapted to slide-fit about the inner edge portion of the core leg. A recess is provided in the leg of the core opposite the slot on said module. The retainer includes a frangible lug portion which is adapted to be displaced against the portion of the leg in which the recess is formed. Whereupon, when the lug is softened by ultrasonic energy, it flows into the recess and hardens therein while bonding to the contiguous portions of the retainer to fasten the module in fixed assembled relation on the core.

Abstract: A two pump skimmer system for recovery of lighter-than-water hydrocarbons from water wells. A water pump is used to depress the water table and a contaminant pump is used to remove the hydrocarbons. The pumps are located in individual chambers which are interconnected, with the water chamber below the hydrocarbon chamber and with limited one-way flow into the water chamber. Both pumps are independently controlled by sensors in the upper chamber to assure that each pumps only the proper liquid.

Abstract: An achor bolt assembly for securing a bolt in a bore hole is provided with supporting members for applying pressure against an area surrounding the mouth of the bore hole wherein contacting surfaces of the supporting members are provided with a coating of a latent lubricating material which becomes an active lubricant in response to heat generated as the bolt is rotated and tensioned in the bore hole.

Abstract: Stabilized acrylic resin having a core of acrylic polymer and a substantially linear stabilizer having one polymerizable functional group at one end of the stabilizer molecule, the resins being useful as rheology control agents for coating compositions.

Abstract: This invention relates to an aircraft having three lift surfaces, and precisely a main wing lift surface located in an intermediate position of the aircraft and two less extended lift surfaces positioned, respectively, in a position ahead of the main wing surface and astern thereof.

Abstract: The present invention is a magnetic tape-based "voice mail" multi-user message system. The system transmits audio prompts to callers to help guide them through the various procedures. The callers respond with Touch-Tone commands. A novel circuit is provided to detect these tone commands without significant interference from the audio prompt signals. This circuit is highly insensitive to deviations in the impedance of the incoming telephone line from its expected value. A circuit is also provided to prevent Touch-Tone commands which are recorded on tape from being re-executed when they are played back from the tape. A single L.E.D. indicator on each recipient's telephone set indicates the status of the system: idle with new message waiting; idle without new message waiting; busy with new message waiting; or busy without new message waiting.
