Abstract: The invention provides methods and devices for the electrochemical generation of nitrogen from organic nitrogen compounds, such as hydrazides (RCONHNH2), the corresponding organic hydrazino-carboxylates (RCO2NHNH2) and amino-guanidine salts (e.g. aminoguanide bicarbonate H2NNHC(NH)NH2.H2CO3). In the hydrazides and hydrazino-carboxylates, “R” may be an alkyl, alkenyl, alkynyl or aryl group, in some embodiments methyl, ethyl, or benzyl. The alkyl, alkenyl and alkynyl groups may be branched or unbranched, substituted or unsubstituted.

Abstract: Apparatus and a process are disclosed for cleaning and/or fluxing circuit card assemblies. The assemblies are moved through an enclosure in which they are sprayed with cleaning and/or fluxing liquid from fenestrated cylinders rotating above and below the path of the assemblies and disposed laterally thereacross. The complex spray impact pattern created by the simultaneous movements of the assemblies and the cylinders effects thorough cleaning and/or fluxing of the assemblies. Separate control of liquid pressure from the cylinders prevents unsoldered components from being dislodged from the assemblies during cleaning and or fluxing.
Abstract: A modular "full bleed" panel system with interchangeable interconnecting elements for creating display booths, room dividers and the like. The system comprises a series of modular panels of different shape, construction and function, together with a series of modular connector elements adapted to interconnect with each of said panels to form any of a variety of highly stable structures which present a visually unitary appearance and in which the connector elements are not significantly visible.
Abstract: An in-line pipe coupling comprising a joint housing which encloses a piston means having a standard diameter pipe section which protrudes from one end of the joint housing may be compressed and inserted into a small cutaway section of existing pipeline and then expanded to fit over the two free ends of pipe, forming a continuous water-tight connection. The slip joint may be utilized in conjunction with either a standard straight pipe coupling or a T-coupling or cross coupling in order to facilitate addition of one or more branch lines to an existing pipeline.
Abstract: A swimming simulation exercise device is described. The device comprises a frame supporting a platform on which the user rests, arm cranks for simulating swimming stroke motions and resistance means for the user's legs to allow the user to simulate a kicking motion. The platform is preferably mounted on a gimballing apparatus which allows the user to simulate the normal rocking motion inherent in swimming. The apparatus incorporates means for providing a "simulated water line" effect such that the user encounters resistance to arm strokes during the lower half of the stroke (in which the arm would normally be in the water during swimming) and little or no resistance on the upper half of the stroke. Accessory devices such as heart rate monitors, lap/distance counters and the like can be attached to the device.
Abstract: An improved catalytic heater for heating an oxidizing gas, normally air, that contains a small percentage of a catalytically oxidizable gas, normally hydrogen, and a novel method of operation within the catalytic heater. A preheat catalytic chamber is defined within a primary catalytic chamber, and the air/hydrogen mixture is first flowed through the preheat chamber and then through the primary chamber, so that the gas will first be catalytically preheated as it passes through the preheat chamber and will be further heated within increased thermodynamic efficiency because of the preheating as it passes through the primary chamber.
Abstract: A copper-based alloy is described consisting essentially of:______________________________________ Tin 25-225 ppm Tellurium or Selenium 25-225 ppm Phosphorus 10-50 ppm Copper Balance ______________________________________The alloys can be used in many forms, including sheet, strip, bar, rod and wire. Sheet stock made from this alloy is useful as automotive radiator fin stock. In addition, electrical components can be made from the alloy of this invention. All of these materials have thermal and electrical conductivity properties and softening temperatures equal to or better than the prior art alloys adapted for these applications. In addition, the alloys of this invention can utilize relatively inexpensive materials and do not present significant toxicity problems and are readily analzyed using common industrial analysis equipment.
Abstract: An improved lubricant and coolant removal system for a roll stand includes suction boxes surrounding the sheet formed by the roll stand and a series of pipes connecting the suction boxes to various coolant traps. Special doctor blades and air knives remove coolant from the rolls. An enclosing shroud prevents coolant overspray and mist from escaping.
Abstract: An image-forming composite image member and subtractive photo process employing that composite, in which composite, a spectrally reflective light-blocking layer, a secondary thin optically functional layer and a subtractive photosensitive layer are carried on a base in an association, in which the reflective layer and the secondary layer cooperate after imagewise exposure and development to define an image member in which the secondary layer and reflector layer may provide a guide to orientation of the composite and may provide a unique polarity-reversing ability to display both a negative and a positive image. In a preferred form, the reflective and secondary layers provide superior uniform light-blocking with a minimum combined thickness, and also cooperate in the photo process during the development to insure rapid and complete clearing of areas with at most minimal mechanical action under portions of the photosensitive layer which are soluble after imagewise exposure and have been removed in development.

Abstract: A process is described for the direct chlorination of hydrated alumina (preferably alumina trihydrate) to aluminum chloride hexahydrate (ACH) by reaction with concentrated hydrochloric acid. Preferably all of the initial hydrated alumina is converted to ACH. The ACH partially calcined to form an amorphous mixture of aluminum oxides and oxychlorides. This mixture is then reductively chlorinated to form anhydrous aluminum chloride which is suitable as a source of electrolytically produced aluminum metal.
Abstract: An audio processor which converts monaural input to a realistic pleasant sounding binaural output in which optical coupling means, having a nonlinear transfer characteristic, creates an unbalanced output to a pair of audio outputs. The system provides for a high or low level input, which may be selected by a switch, to an emitter follower which drives an optical coupling circuit. The optical coupling circuit is comprised of a light emitting diode and a phototransistor connected in a phase splitting network. The phase splitting network provides an unbalanced output to terminals for connecting to preamplifiers, amplifiers, etc. An alternative embodiment employs two optical coupling circuits in two separate signal processing channels, including two phase splitting networks.
Abstract: A remote camera viewfinder has a fiber optic bundle with a fitting at one end adapted to attach to the eyepiece of a camera and a fitting at the other end for allowing a photographer to see through the fiber optic bundle. The camera end fitting has a lens for focusing the image onto the focal plane of the fiber optic bundle. The other fitting includes a lens adjacent to the end of the fiber optic bundle to magnify the image transmitted through the bundle and also includes an eyecup mounted to a helmet or headgear arrangement which holds the eyecup adjacent to the photographer's eye allowing both hands free for manipulation of the camera.
