Abstract: A gas containing methane and water is treated in order to remove water therefrom. The process comprises a step of contacting the gas with a liquid phase formed of water and solvent, whereby water free of solvent can be removed, and a subsequent step of cooling the resultant gas. The process is applicable to natural gas and to refinery gas.

Abstract: Heat and/or cold are produced in an absorption heat converter operated with a solvent and at least two distinct working fluids condensed and vaporized in a temperature range, whereby the yield is increased.

Abstract: Process for separating the components of a gaseous mixture, saving energy and operating by demixing wherein the mixture to be separated is contacted under extracting conditions with a solvent which is then cooled down to a demixing temperature to provide two liquid phases, one of which has an increased extract content and the other an increased solvent content. The extract is recovered and the solvent recycled. The process can be used for numerous applications in the field of gas treatment.

Abstract: Cold is produced in a phase separation cycle comprising the steps of (a) compressing a refrigerant fluid and dissolving it in a solvent, (b) cooling resultant solution to form two distinct liquid phases, (c) separating the liquid phases, (d) recycling the heavy phase, (e) expanding and vaporizing the light phase to produce cold, and (f) recycling the vaporized light phase. A portion of the cold produced in step (e) is used to cool the solution from step (a), and another portion is used to cool an external medium.

Abstract: System for storing thermal energy obtained from a heat source operable in a discontinuous manner, such as a solar collector, comprising the successive steps of using this thermal energy to raise the temperature of a solid substance, dispersed in a liquid, above its melting point so as to obtain an emulsion of said substance in said liquid and of using a cold source in thermal exchange with said emulsion to decrease the temperature of said emulsion so as to obtain a dispersion of solid substance in the liquid and further comprising means for storing the obtained emulsion or dispersion under adiabatic conditions before proceeding to the following step.

Abstract: A miniature manually actuated switch is grippingly received over an edge of a printed circuit board or card and has a selector for selectively bridging circuit paths on opposite sides of the card. Electrical contacts with the selector captivated there between are resiliently biased into positive gripping relationship on the card.

Abstract: The invention relates to a manually actuated switch of miniature size wherein a circuit path is completed between poles of the switch by a contact having independent cantilever beams contacting a respective switch pole. The contact is carried by a manually displaceable sliding element in the form of a carriage. Movement of the carriage causes wiping of the cantilever beams over a substantial length of the switch poles. To interrupt the circuit the sliding element is moved to an extreme position whereby one of the beams is slidably traversed off a corresponding switch pole and into abutment against a dielectric projection which prevents chatter of the disengaged beam. Detenting action for precise positioning of the slider element is accomplished by sliding at least one of the cantilever beams over an irregular surface of one of the switch poles.

Abstract: A rocker action switch is disclosed of dip configuration to be pluggably mounted in a printed circuit board or mounted to a panel with clips. A carriage having bridging contacts is slidably displaced within the housing to selectively engage the bridging contacts with selected switch poles. A pivotable control knob has a projecting lever that engages and slidably actuates the carriage. The switch may be constructed with interchangeable parts to perform various switching functions such as momentary, double-pole single-throw or double-pole double-throw with positive detent action. Assembly of the switch is simplified by vertically stacking the component parts within the housing.

Abstract: A manually actuated switch includes a pair of terminals forming switch poles and a knob which is manually actuated to complete or interrupt an electrical circuit across the poles. A pair of spaced contacts are embedded in the knob and resiliently grip therebetween a diode which controls current direction of the completed circuit.

Abstract: A miniature switch utilizes a flexible diaphragm which seals the switch. The diaphragm is compressed sealably against a cover by a spring biased inverted cup which compresses the diaphragm outwardly against the cover. The switch is actuated by pressing the diaphragm to displace the cup against the biasing action of the spring. The cup is conductive and bridges across poles of the switch to complete a momentary switch operation.

Abstract: A manually actuated momentary switch completes an electrical circuit for lighting a low voltage indicator light advantageously used for testing circuit continuity. The switch and indicator light are in combination within a miniature size housing having depending electrical terminals for pluggable connection on a printed circuit board.

Abstract: A miniature momentary push button switch includes a light emitting diode mounted in a dual-in-line package having rows of electrical leads for pluggable connection in a printed circuit board. The electrical leads provide an interruptible circuit path through the package and are fabricated from a standard lead frame. The circuit is normally open and is momentarity closed by manual actuation of a push button. For ease in manufacture, the interruptible circuit path is not electrically connected to the diode within the package. Instead the depending electrical leads are capable of pluggable connection to a circuit means which connects the diode electrically in series with the interruptible portion of the circuit by any one of a variety of techniques.
