Abstract: A method for constructing an infrared detector array directly upon a detector interface device is disclosed. The detector interface device mechanically and electrically connects the infrared detector array to signal processing equipment. In a first embodiment of the invention encapsulated single crystalline material is formed within a cavity formed in a substrate. The encapsulated single crystalline material formed within the substrate cavity is suitable for use as a seed crystal for graphotaxial crystal growth of a detector element support layer across the surface of the substrate. Detector elements can then be formed upon the detector element support layer. In a second embodiment of the invention a plurality of detector element support layers can be formed within an array of cavities formed upon the substrate. An individual infrared detector element can then be formed directly upon each of the detector element support layers to form a detector array upon the substrate.

Abstract: A method for forming an array of single crystalline seed crystals separated by an insulator and suitable for use in the formation of infrared detector elements is disclosed. The seed crystals are formed from a single crystalline substrate having first and second planar surfaces. An array of grooves is formed in the first planar surface of the single crystalline substrate such that a plurality of protrusions are formed upon the first planar surface of the single crystalline substrate. The grooves are then filled with an insulator. A portion of the second planar surface of the substrate is then removed to expose the insulator disposed within the grooves to form an array of single crystalline seed crystals. The single crystalline seed crystals are separated by the insulator. The single crystalline seed crystals and the insulator are exposed upon both the first and second surfaces of the array.

Abstract: An obturator is provided which allows for placing and withdrawing of a single catheter obturator over an extended period of time so as to allow spaced intervals of use, and non-use of a catheter while in place in the patient's skin, while at the same time doing away with cumbersome, costly and time consuming administration and maintenance of saline and heparin locks. The device feeds the obturator in place for occluding the catheter lumen, when no fluids are being administered to the patient, and then may be retracted to a position allowing fluid feed through a supply tube connection to the catheter. The device includes a coating on the obturator rod which swells in contact with aqueous fluids to seal completely the catheter lumen which coating includes heparin to prevent clotting. Moreover, the entire internal functioning arrangement remains sterile during the entire period of use, thus avoiding infection.

Abstract: The specification discloses a spent seed recovery and regeneration process for an MHM power plant employing an alkali metal salt seed material such as potassium salt wherein the spent potassium seed in the form of potassium sulfate is collected from the flue gas and reacted with calcium hydroxide and carbon monoxide in an aqueous solution to cause the formation of calcium sulfate and potassium formate. The pH of the solution is adjusted to supress formation of formic acid and to promote precipitation of any dissolved calcium salts. The solution containing potassium formate is then employed to provide the potassium salt in the form of potassium formate or, optionally, by heating the potassium formate under oxidizing conditions to convert the potassium formate to potassium carbonate.

Abstract: A method and apparatus for establishing telephone communications between anonymous service subscribers and responding callers over public telephone lines employing the Direct Inward Dialing (DID) feature to enable complete confidentiality and mutual anonymity between a caller and a subscriber and to effect immediate connecting to a subscriber without touch tone or verbal input. The system also is used as an unpublished telephone number service to enable a caller to place a message that is relayed to a subscriber. The subscriber, based on the caller's message, then can return the call to communicate with the caller. Further, the system may be used to enable a subscribing caller to place calls to persons having caller identification telephone equipment capable of identifying the telephone numbers of callers.

Abstract: A golf sling, using a tether made up of a joined resilient and a non-resilient line, uses a conventional golf ball attached to one end and an anchor attached to the opposite end to permit practicing golf in a limited area. A connector from the tether to an anchor permits using either a pin forced into the ground or a snap attached to a golf bag as an anchor. An adjustable device for the length of the resilient section permits selecting a length to change the tether characteristics appropriate to the club in use. The resilient portion can be made of a plastic coil or an elastic strap. A modification to the coil uses a spring through the coil to permit selecting a spring constant separate from the damping constant for greater flexibility. The golf ball can be permanently attached to the tether, or can be adapted to be readily changed by a variety of attachment devices. A tee and a tee holding ring can be attached to the tether for golf club wood use.

Abstract: A method capable of detecting low concentrations of a pollutant or other component in air or other gas, utilizing a combination of a heating filament having a catalytic surface of a noble metal for exposure to the gas and producing a derivative chemical product from the component, and an electrochemical sensor responsive to the derivative chemical product for providing a signal indicative of the product. At concentrations in the order of about 1-100 ppm of tetrachloroethylene, neither the heating filament nor the electrochemical sensor is individually capable of sensing the pollutant. In the combination, the heating filament converts the benzyl chloride to one or more derivative chemical products which may be detected by the electrochemical sensor.

Abstract: A process for forming a single trench MOS transistor/capacitor cell for analog signal processing, and the resulting structure, are disclosed. The transistor is formed by foming a first trench in the semiconductor substrate, lining the trench with a layer of insulating material, a layer of conducting material, and filling the trench with a layer of insulator. A doped region is formed adjacent the trench, which serves as a transistor source. A second trench is then formed which extends through and excavates a portion of the first trench. The second trench is lined with a layer of doped material and insulator. The doped material is isolated from the conductive layer lining the first trench. The second trench is then filled with a body of conductive material. The layer of doped material lining the second trench serves as the transistor drain and a capacitor output is extracted from the body of conductive material.
