Provision is also made for the control of an RF power source to maintain power at the load at a preset level irrespective on impedance fluctuations and reflections.

Abstract: A radio fequency amplifier-combiner using series fed directional couplers in an input distribution network each coupler having an amplified output to a respective coupler in an accumulator providing a high energy output with low accumulator losses. The invention can be used in waveguide with capabilities of output power levels reaching hundreds of watts and more.

Abstract: High temperature furnaces are described containing a movable viewing window that is heated so that the work charge can be scanned along the length of the furnace without creating a thermal disturbance. A system is also disclosed for controlling the operation of the furnace based on comparison of viewed images with stored sample images.

Abstract: A ball valve is described having a latching handle with a latch plate having raised lugs that engage the handle, a latch mechanism or both to act as detent stops in predetermined rotational positions. A flat spring rolled at one end urges the latch mechanism into the latched position and a pivoting cap secured to the handle is latched by simultaneous action of the latch mechanism to block access to a nut securing the handle assembly. Provision is made for attaching a padlock.

Abstract: Small scale recrystallization apparatus is described using a container tube and a plastic plug with the end of the plug and a constriction in the tube mismating in a precisely controlled ellipticity of one so as to allow passage of solution while blocking formed crystals.

Abstract: A swimming pool cleaning brush is disclosed having a pivotal vane that uses fluid dynamics for increasing contact pressure of the brush with the surfaces being cleaned during forward motion and then pivots to a nonimpeding position upon backward motion. The vane is designed to enable after market installation and is economically formed from two or three pieces of flat metal or plastic with necessary fasteners.

Abstract: Spinning band fractionating column apparatus is disclosed having a spinning band formed with a magnet embedded in its bottom end in the manner of a magnetic stirring vane for rotation by a rotating external magnetic field at the bottom of the apparatus. Reflux is controlled by an angled drip edge on a rotatable condenser column that passes a portion of dripped condensate to a collecting spout with the portion varying as rotation of the condenser column brings the drip from said edge closer or further from center opposition with the spout.

Abstract: Apparatus and a process for collecting the output of a gas chromatograph are disclosed in which a heat sinking adapter at the output port of a gas chromatograph is connected to a collection tube having bulbous enlargements for collecting condensate and a ground tapered end for making a tapered seal to a tapered throat in the adapter. A collection vial with a conical cavity and having the same tapered throat as the adapter accepts a transfer of the collection tube from the adapter and is suited for direct installation into a centrifuge. The disclosure is of particular interest in microscale preparative gas chromatography.

Abstract: A pilot valve for connecting a source of fluid under pressure to an actuator where the pilot valve may be connected to the actuator in any of 360.degree. of rotation so that the fluid connections may be made from any desired direction. Further disclosed is a coupling adapter joining the pilot valve to the actuator with passages so arranged in the adapter that 180.degree. rotation of the coupling adapter reverses the fluid flow connections between the pilot valve and the actuator simultaneously exposing indicia indicating the condition. Still further disclosed is a spring return manual override that is slotted to enable operation by a coin and has a mating slot in the pilot valve body allowing locking in the override position by insertion of a coin or similar device. A ball valve actuator is described as an actuator device.

Abstract: Disclosed are fiberoptic cables with angled coupling adapters such that the finished face of the terminal connector has an axis offset from that of the primary terminal assembly.

Abstract: A watering container for birds having spaced inner and outer walls integrally molded from plastic with electrical heating elements contacting the inner wall controlled so that energy is provided to the heating elements is progressively increased with the fall of ambient temperature below freezing.

Abstract: A watering container for domestic animals having spaced inner and outer walls integrally molded from plastic with electrical heating elements contacting the inner wall controlled so that energy provided to the heating elements is progressively increased with the fall of ambient temperature below freezing.

Abstract: Handle assemblies for fluid control valves are described that can be operated from various positions and in either direction of rotation to open and close 90.degree. operating valves. A detenting element passes through a selectable one of a plurality of notches in a handle arm to engage fixed stops on the valve and sets limits at various positions depending on the selected notch.

Abstract: A fiberoptic cable assembly is described with terminal connectors in which a coupling element encloses the fiberoptic fibers and has a sleeve portion over which the fiberoptic sheath is secured and a larger diameter hollow portion carrying discontinuities on its exterior surface for engaging a strain relief tubing. A cup washer is locked against the coupling element by a locking element that serves as the connecting terminal of the cable. The cup washer is designed so that its cupped portion encloses the end of the strain relief tubing and presses it into the discontinuities securing the tubing in place.

Abstract: A furnace and method producing a precisely controlled temperature gradient within a central bore by a plurality of heating elements sandwiched between respective insulating layers with each heating element loosely thermally coupled to a thermally conductive ring extending concentrically outward from the furnace bore. Thermal sensors at each layer provide data to data processing equipment which controls and moves temperature gradients within the furnace by program.

Abstract: A surgical headlamp is disclosed that is removably mounted to a headband and which utilizes a remote light source connected via a fiberoptic cable. The mounting arrangement includes frictional sliding members permitting adjustment of the lamp to an exact in between the eyes location.

Abstract: A flash beacon is described which uses a strong bright initial flash to attract attention followed by a series of weaker flashes to enable a person to easily locate the beacon source. The weaker flashes may be broken into code groups for identification or other purposes. An electrical circuit utilizing three capacitor banks interacting with each other, is described for operating the flash sequences.

Abstract: A pollutant storage system that provides substantial wall strength with greatly reduced concrete mass. Reinforced concrete panels precast with a pattern of surface cavities and supported by precast reinforced concrete A-frames enclose a paved floor area.

Abstract: A biocidal composition suitable for use as a stabilizer in polymer systems using 2-mercaptopyridene-1-oxide or a derivative combined with an organophosphorous compound and a benzotriazole wherein the organophosphorous compound and the benzotriazole act together to stabilize the mercaptopyridene against degradation and discoloration of the polymer system.
