Abstract: Method and apparatus for analyzing energy emanating from a source by converting energy from the source into spectral components distributed according to frequency along a flat field, combining the spectral components into a beam, detecting the beam which combines the spectral components and demodulating the spectral components.

Abstract: Analysis of energy emanating from a source having a focal plane by converting the energy from the source into modulated spectral components simultaneously distributed according to frequency along a flat field, using, for example, a modulator, and then detecting and demodulating the spectral components, for example by a fast Fourier transform or synchronous demodulator with a ruled grating interposable between the source and the detector and a linear variable bandpass filter interposable between the source and the detector.

Abstract: A rapid fire electromagnetic launcher system (EML) employs a plurality of capacitor modules which are charged by an equal number of modules of lead acid batteries. The invention comprises the combination of standard automotive lead acid batteries for charging an electrolytic capacitor array which is switched into an Electromagnetic Launcher (EML) by means of silicon controlled rectifiers, and a control circuit for controlling the loading and launching of projectiles at a very rapid rate. The system includes a multishot preinjector and rapid fire controller for operating the system in a safe and reliable manner. The system includes a preaccelerator, magazine and barrel. The combination eliminates the low power density limitation of the batteries, the requirement to repetitively commutate energy out of an inductor, and allows for a modular system than can be expanded to provide higher energy to each projectile in the burst.

Abstract: Method and apparatus for identifying a refrigerant by determining the spectrum of the refrigerant in the absence of a sensing reagent and converting the spectrum into an indicium of the type of refrigerant.

Abstract: Valve apparatus and method with an elastomeric disk fixedly disposed between inlet and outlet members and being deformable to permit flow through the inlet to the outlet. Deformation of the disk in the direction of pressure through the outlet is limited. The elastomeric disk can be circular with a linear or non-linear slit and be clamped between the inlet and outlet members. The structure for limiting disk deformation can take the form of a pilot integrated into, and extending across, the inlet member in centrally or non-centrally apertured form.

Abstract: Apparatus for detecting motion by producing a signal in response to motion, transmitting the produced signal and receiving the transmitted signal which is converted to auditory and electrical outputs, with an ear phone jack connected to an auditory output, an on-off switch connected to the signal converter and a set of indicator lights connected to an electrical output.

Abstract: Holding of a vehicular door by controllably and securely engaging the door in any of a large number of prescribed positions, particularly while leaving or entering the vehicle. The selected positions can be held securely by a ratchet and pawl, a friction brake or electromagnetic engagement. The door holding mechanisms can be mounted on the vehicular door and frame, and be activated and released by essentially the same actuator, which illustratively is electromechanical.

Abstract: Method and apparatus for protecting a device at a first location using an operational member, within the device at the first location, that is activated by a control unit at a second location, separated from the first location, including an activation switch that enables the generation of a signal for rendering the device operational at the first location.

Abstract: Method and apparatus for the display of objects by at least one screen disposed between inner and outer frames for suspending objects; a plurality of screens with different meshes can be employed in order to adapt the display to the suspension of different classes of objects; and the inner frame can have a beveled surface facing the screen to facilitate the placement of objects on the screen.

Abstract: An improved balloon catheter is disclosed that facilitates catheter release when a pull is entered upon the inserted catheter while the balloon is inflated in a body passageway. The catheter is provided with one or more weakened regions on the inflatable balloon portion. These weakened regions may be provided by portions of non-uniform thicknesses arranged circumferentially around the balloon. These weakened regions rupture and release the inflation when the catheter is pulled from its inserted, inflated position. This mechanism allows for a tight seal on the body passageway while alleviating the danger of accidental removal with the balloon in its inflated state.

Abstract: A self contained catalytic heating device within which a fuel/oxidizer mixture and combustion products are held out of physical contact with a heated medium, allowing the temperature of the catalytic material to be maintained at a level that is independent of the temperature at the surface in contact with the heated medium; materials and geometric dimensions can be chosen to achieve required temperatures for catalytically coated surfaces and heating surfaces, for example in a tubular construction.

Abstract: Thin polymeric films, coatings and ionic conductors by cross-linking a polymer matrix, such as a polyethyleneimine, polyetheramine, polyallylamine or polyacrlyamide, with a fluorocarbon containing epoxide or anhydride. The compositions are of high integrity and posses properties, such as insulation, ion conduction, anticorrosion, antifouling and self-adhesion. Specific compositions absorb and release acidic gases and liquids.

Abstract: Footwear which is adaptable for athletic events requiring different sole configurations for different playing surfaces, for example artificial turf and natural turf, by providing the soles of shoes with a prescribed pattern of protuberances which are suitable for one type of event, and altering the pattern to adapt the shoes for another and different type of event. In particular the sole of each shoe can have removable conical cleats for playing on natural turf, and removable stud or square cleats for playing on artificial turf.

Abstract: A flow control device with at least one flow channel in a housing that can contain an injection site and/or a pre-biased flow control diaphragm that is stabilized by a flexible contact member. Any flow channel, including that with an injection site, may include a plug acted upon by an external actuator, which can be self-sealing. The injection site with a flexible plug can be used for needleless infusion of fluids, or the flexible plug may be used with a needle for the conventional injection of fluid.

Abstract: Precision control of fluid flow by a body containing an inclined surface opposite an elongated opening, with a slider inserted into the opening to be movable along the opening in contact with discrete portions of the body which desirably includes a hinged detent for making contact with the body.

Abstract: A flow control device in which flow channels converge in a housing containing an injection site and a pre-biased flow control diaphragm. The injection site may include a diaphragm. The diaphragm can be acted upon by an internal actuator or plunger that extends into one of the flow channels where the plunger can be engaged by an external member such as a Luer fitting. The actuator or plunger may be of rigid or flexible construction is at the entry position of an intermediate channel and extends to an output channel of the injection site.
