Abstract: SURGE ARRESTER            Abstract of the Disclosure A surge arrester for protecting telephone lines and the like from overvoltage has opposed carbon electrodes separated by an insulating spacer that houses one of the electrodes and provides a means for spacing the electrodes to define the arc gap therebetween.  The other electrode has one round plateau with a flat end surface that defines one side of the gap.  The plateau is surrounded by a valley structure which provides a maximum of relief or cavity space for carbon particles that erupt from the electrodes during discharge.  The cavity space is used for venting erupted particles across the end of the spacer and thereby provides an increase in the surge life of the arrester,

Abstract: ABSTRACT     Disclosed is a dual loop heat pump system which includes an expansion-compression device defining a chamber therein and including a linearly movable free piston slidably carried in the chamber for linear movement along the chamber.  The free piston divides the chamber into a first subchamber of varying size as the free piston moves along the chamber and a second subchamber of varying size as the free piston moves along the chamber.  The system further has a Rankine cycle power loop having a working fluid and a vapor compression heat pump loop having a working fluid.  Control means provide for selectively introducing the power loop working fluid into the first subchamber at a first pressure to move the free piston linearly toward the second subchamber while inducing linear kinetic energy in the free piston, and for stopping the intro-duction of the power loop working fluid into the first sub-chamber when the free piston reaches a prescribed velocity and linear kinetic energy so that the power loop working fluid and the induced linear kinetic energy in the free piston continues to move the free piston toward the second subchamber. The heat pump loop working fluid is operatively associated with the moving free piston so that the heat pump loop working fluid is compressed and substantially all of the linear kinetic energy induced in the free piston is transferred to the system working fluids as work of compression.

Abstract: ABSTRACT OF THE DISCLOSURE           A stable, dry, non-dairy fat emulsion product suitable for use as a coffee whitener is prepared without the use of protein by incorporating a chemically modified dextrinized starch having a lipophilic character in the formulation.  The chemically modified starch is included in an aqueous emulsion containing fat or oil and a conventional emulsifier to stabilize the emulsion through the drying step so that upon reconstitution in coffee a stable emulsion is formed.  The pH of the liquid emulsion must be controlled in order for the chemically modified starch to be effective in stabilizing the emulsion through the drying step.  A buffering agent is mixed with the dried emulsion to improve the taste of coffee whitened with the dried emulsion.

Flavor enhancement is also shown.  It has also been found that the drying of mineral containing delactosed or deproteinized whey by-product solutions can be improved by mixing from about 5% to about 50% casein or the sodium and potassium salts thereof with the solution prior to drying.  The solution can then be effectively spray dried.  The dried product exhibits reduced hygroscopicity as well as improved physical and chemical properties par-ticularly in the area of comminuted meats.  The percentage is based on the dry solids in the final dried product.

Abstract: ABSTRACT OF THE DISCLOSURE      Acidic gases are substantially removed from a normally gaseous mixture by a process comprising contacting the normally gaseous mixture with an amine-solvent liquid absorbent comprising (1) an amine mixture comprised of at least about 50 mol % of a sterically hindered amine and at least about 10 mol % of a tertiary amine alcohol, wherein said sterically hindered amine contains at least one secondary amino group which is part of a ring and is attached to either a secondary or tertiary carbon atom or a primary amino group attached to a tertiary carbon atom, and (ii) a solvent for said amine mixture which is also a physical absorbent for said acidic gases.  The liquid absorbent may also include up to about 35 weight percent water.  The coaction of the sterically hindered amine and the tertiary amino alcohol in conjunction with the solvent pro-vides an increase in the amount of CO2 containing acidic gases absorbed compared to the use of the same sterically hindered amines alone and lowers the heat of reaction.

Abstract: ABSTRACT OF THE DISCLOSURE         An internal combustion engine comprises a casing and a rotor rotatably mounted in the casing with a plurality of blades formed in the surface thereof.  A power shaft is connected to the rotor and extends out of the casing.  A plurality of circumferentially spaced nozzles in the casing are in line with the rotor blades and extend tangentially in a common direction towards the rotor.  A combustion chamber has an outlet port in communication with the nozzles.  There are exhaust ports in the casing between and aligned with the nozzles.  The combustion chamber has an apparatus for supplying an explosive fuel mixture to the combustion chamber through the fuel inlet port thereof, a spark plug for firing the explosive mixture therein and a mechanism for supplying gas under pressure to the nozzles to start the rotor turning in the casing.   The mechanism to start the rotor turning comprises a piston in the chamber normally urged towards the inlet port. The outlet port in the chamber is closed by the piston when the latter is in its normal position.   The expanding gases of the fired charge force the piston to uncover the outlet port to permit gases to travel to the nozzles to start the rotor turning.  There is a locking mechanism for sewing the piston in a lower position, uncovering the outlet port, when the engine has started.
