Abstract: ABSTRACT OF THE DISCLOSURE          A flexible implant for replacing the scaphoid bone of the wrist includes a one-piece body of resilient material.          The body defines an inferior surface of slightly convex and oval shape with the apex of the surface lying in substantially a single plane and defining a trapezium articulate facet and a trapezoid articulate facet.  A stabilizing stem extends outwardly from the inferior surface and generally perpendicular thereto.  The body further defines a superior surface having a smooth, slightly convex shape and being adapted to articulate with the radius.  An internal surface defined by the body has a lunate articular facet and a deep concavity, the latter adapted to articulate with the capitate.  An external surface of generally smooth and convex shape is bounded by the inferior surface and the superior surface and defines a dorsal edge of the internal surface concavity.  A posterior surface extends between the external surface and the proximal edge of the lunate articular facet.  An anterior surface of generally triangular shape is bounded by the lunate facet, the deep concavity and the superior surface.

Abstract: GAS ANALYZER AND GAS ANALYZING METHOD             ABSTRACT           A gas analyzer and gas analyzing method are described of the non-dispersive infrared type wherein infrared energy is passed through a sample cell contain-ing an unknown mixture of gas.  The infrared energy passing through the cell is received by a detector and an electrical signal is produced representative thereof.  A rotary fitter wheel positions at least one filter in the path of the infrared energy, resulting in a pulsating detector output.  The electrical signal is processes to produce an output indicating the concentration of the constituents of the gas mixture in the sample cell. Synchronization with the processed electrical signal is obtained by deriving synchronizing pulses directly from the electrical signal produced by the detector.

Title: Power generation by exchange of latent heats of phase  transition
Inventor: EHRLICH STEFAN
IPC: F01K25/10
Filed: 1980-04-08
Granted: 1982-05-18
Abstract: ABSTRACT OF THE DISCLOSURE    A power system is provided that uses the latent heat of fusion of water to raise the potential energy of a working fluid to a level that upon release generates power, preferably electrical power.  The system is self-sustaining except for the energy that is supplied in water entering the system.          The inlet water can be at any temperature within its liquid range under atmospheric or super atmospheric pressure, can advantageously contain the sensible waste heat typical of effluent from fossil fuel or nuclear power plants, can be relatively pure or be contaminated as with sewage or be the medium of a colloidal suspension, or consist of marine or other saline waters.  In every case, purification of the water by freezing, for example, desalination, is accomplished without additional power consumption.    A selected working fluid that boils at a temperature substantially below the freezing point of water is brought in the liquid state into contact with the water or other aqueous medium, causing the water to freeze and the working fluid to vaporize under pressure; the produced ice is removed; a portion of the so-produced ice is admixed with a eutectic forming salt to create a cooling medium at a temperature below the condensation temperature of the cooling fluid; the working-fluid vapors are preferably superheated by inlet aqueous medium and are released from autogenic elevated pressure to drive a turbine.  Working fluid vapors are condensed by said cooling medium and returned by pumping into contact with inlet aqueous medium.

Title: Use of microwave energy in the  production of plasticizer esters
Inventor: BHARGAVA NARESH
IPC: C07C67/08
Filed: 1980-06-12
Granted: 1982-07-20
Abstract: ABSTRACT OF THE DISCLOSURE:           The invention is concerned with an improved process of preparing plasticizer esters by reacting aliphatic or aromatic dicarboxylic or tricarboxylic acids or their anhydrides and aliphatic alcohols of 1 to 15 carbon atoms while continuously removing the water of reaction,  wherein the improvement comprises carrying out the esterification under irradiation with microwaves.          The invention provides an esterification process which has very short reaction times  achieves high conversion of reactants, reduces the degradation of materials and results in products having significantly low contents of free alcohol and moisture.          In particular, it has been found that the use of microwaves in the production of plasticizer esters has the effect of accelerating the rate of reaction considerably.

The tool is powered and includes a fluid motor typically energized from a remote source of high pressure air.  The data processor is energized by either a battery or an AC source.  Termination of tool operation is effected by energizing a solenoid in response to a shut off signal generated by the data processor.  In a battery operated embodiment, tool operation is initiated by manual depression of an operating lever while tool termination is effected automatically in response to the shut off signal,  This mode of operaton reduces the number of required batteries, prolongs battery life and reduces the number and size of electrical components in the tool.

Abstract: ABSTRACT            A hydraulic elevator is employed having the usual call buttons at the respective floors and selector buttons for all floors located in the elevator cab.  When a button is pushed to select a floor to which the cab is to travel, up or down, as the case may be, the cab starts moving slowly in the selected direction.  During initial movement a cam on the cab triggers components in an electric cir-cuit which, by motivating hydraulic valving causes the cab initially to accelerate to a selected rate of travel after which travel proceeds at the selected rate to a slow down point.  At that point another component is trig-gered and the valving causes the cab to decelerate for a selected interval of travel, after which the cab moves slowly to the level to which it was called.
