Abstract: The present invention is a method of extracting the oxygen-containing flavor and fragrance compounds from oils obtained from natural products. Extraction is accomplished by the use of cold water typically below 100° C., but more typically below 50° C., to produce a weak aqueous solution. The oxygen-containing compounds are then concentrated by adsorption on to an appropriate solid material and then washed off by an organic solvent, such as ethanol. The resulting product is a solution in the organic solvent.

Abstract: A cable reel comprises a casing defining a cable exit opening and an access opening; a static electrical connection located externally of the casing; a spool rotatably received within the casing and having a circumferentially extending recess opening radially outwardly of the spool, the spool further having an inner axially extending recess and an axially open notch communicating between the circumferentially extending recess and the inner axially extending recess; a handset cable having a first end and a second end, the handset cable first end being attachable to a handset in use, at least a portion of the handset cable being windable into or out of the spool circumferentially extending recess upon rotation of the spool so as to extend from or retract into the cable exit opening; a ribbon cable having a first end and a second end, the ribbon cable first end being attached to the handset cable second end and the ribbon cable second end being attached to the static electrical connector whereby the ribbon cable

Abstract: A compressed gas, e.g. carbon dioxide, is injected under pressure into a press to increase the yield of oil from a natural material. The effect is brought about by the gas dissolving in the oil. The mass of gas required is typically less, often much less, than the mass of natural product.

Abstract: A cradle 13 for a handset for a telephone or other electronic apparatus is dimensioned to fit within a chair arm, for example an aircraft seat arm. The cradle includes an integral cord spool 16 having a rewind bias spring 34, and a catch (not shown) for maintaining the handset in the cradle. The cord is locked in an extended condition by a braking cam 53, releasable for rewinding the cord by a pushbutton 36. Latching means 54 are provided for maintaining the pushbutton depressed until the cord is rewound. Other brake and latching means, including a ratchet and pawl arrangement, are disclosed.

Abstract: The method of the present invention is adapted to manipulate the chemical properties of water in order to improve the effectiveness of a desired process. The method involves heating the water in the vessel to subcritical temperatures between 100° to 374° C. while maintaining sufficient pressure to the water to maintain the water in the liquid state. Various physiochemical properties of the water can be manipulated including polarity, solute solubility, surface tension, viscosity, and the disassociation constant. The method of the present invention has various uses including extracting organics from solids and semisolids such as soil, selectively extracting desired organics from liquids, selectively separating organics using sorbent phases, enhancing reactions by controlling the disassociation constant of water, cleaning waste water, removing organics from water using activated carbon or other suitable sorbents, and degrading various compounds.

Abstract: A track circuit receiver with a synchronous detector is provided wherein the phase of the reference voltage is caused to automatically follow that of the input voltage, so that there can be no reduction in output signal level as a result of phase differences between input voltage and reference voltage. Fail-safe operation is achieved by inverting the phase of the reference voltage and monitoring the rate of phase change at the output. The track circuit receiver of the present invention additionally utilizes simplified circuitry to achieve the foregoing.
