Title: Pavilion with series of arches and method of constructing it
Inventor: HUDDLE CARL F
IPC: E04H15/20
Filed: 1971-10-21
Granted: 1979-02-27
Abstract: ABSTRACT OF THE DISCLOSURE          A tent-like structure, hereinafter called a tensioned vaulted structure that has a series of arches and a panel of flexible covering material or membrane attached to and tension-ed between each pair of arches.  In one embodiment, the arches on each side of an intermediate portion of the pavilion are mounted to swing in opposite directions between upright and recumbent positions.  The arches, except the outermost, are mounted to swing on offsets which increase in length toward an intermediate portion of the pavilion to facilitate attach-ing of the covering material to the arches and to tension the covering material.  The covering material between each pair of arches is depressed to minimize flutter and vibration and to enhance its load-carrying capacity and is attached to the arches by inserting beads on its edges into tunnels and held therein by a locking strip.  In another embodiment, the arches are movable toward and away from each other to attach the covering material to the arches and to tension the membrane.          The invention also includes methods which facilitate con-structing such a structure with the panels of covering material depressed and tensioned between the arches.  The structure may be made of curvilinear, circular or ellipsoidal form as well as straight.

Abstract: ABSTRACT OF THE DISCLOSURE           Ammunition rim fire priming mixtures are commonly prepared by mixing normal lead styphnate, a sensitizer, such as tetracene, an oxygen donor such as lead nitrate, and a frictionator such as ground glass.  This invention relates to such a mixture and to center fire priming mixtures which consist of lead styphnate, tetracene, inorganic fuels and barium nitrate and to a method of forming them and is characterized by the use of lead styphnate which is formed in situ by the reaction of a water wet mixture of styphnic acid and a lead compound such as lead oxide (litharge), lead hydroxide, basic lead carbonate, of lead carbonate.  The lead styphnate which results from the practice of this method has been isolated and subjected to X-Ray diffraction analysis confirming that this is a novel form of lead styphnate and is indeed a new compound.          Important advantages of this invention are reduced cost, improved safety since it is unnecessary to prepare, precipitate, or separately handle pure or relatively pure lead styphnate and because the wet mixtures are insensitive, and improved percussion sensitivity of the resulting mixtures when dried for use.

Title: Preparing thermo-plastic or elastomeric materials for cross-linking of grafted silane

Abstract: ABSTRACT OF THE DISCLOSURE         Siloxane cross-linking of polyethylene is carried out under in situ development of water by chemical reaction between an organic acid and a non-hygroscopic metal oxide producing a neutral salt and water.          Specifically, an ester peroxide is used as additive to be mixed with silane and polyethylene.  The ester peroxide decomposes during grafting in free acid, alcohol and graft initiators for obtaining the grafting of silane on polyethylene, and the acid reacts with zinc oxide or tin oxide, also used as additive, to obtain salt and water.  Alternatively, stearic acid or adipic acid and zinc oxide or tin oxide are added to a polyethylene silane mixture to develop water and salt of the acid.  The present invention is a useful improvement over the prior art in that it permits a more careful control of the stoichiometry  of the cross-linking reaction re-sulting in a more uniform product while doing away with the necessity for a water bath.

Abstract: SOLAR ENERGY COLLECTION SYSTEM     ABSTRACT OF THE DISCLOSURE         A multiple tube solar energy collector having a diffusely-reflecting surface positioned behind the collector tube array.  Multiple double walled collector tubes are con-nected into a manifold for circulation of a working fluid through them.  The working fluid is heated by solar energy as it flows through the tubes.  A diffusely-reflecting sur-face behind the tubes reflects back to the tubes both direct beam and diffuse solar radiation which fails to strike the tubes directly.  This system allows efficient operation of a tubular solar energy collector without requiring focusing or polished reflecting surfaces.  The tubes are preferably no more than four tube diameters apart, on centers, and no more than four tube diameters above or separated from the diffuse-reflecting surface.

Abstract: Interox Chemicals Limited Epoxidation Abstract The invention provides a process for epoxidation of an alkene by reaction with a peracid, characterised by supplying an aqueous phase comprising sulphuric acid, hydrogen peroxide and water and an organic phase comprising acetic acid or propionic acid in a chlorinated hydrocarbon solvent to a liquid-liquid extraction device in such manner that these two phases pass in countercurrent through the extraction device;  withdrawing from such extraction device an organic solution of peracid and carboxylic acid in the chlorinated hydrocarbon;  passing said organic solution and the alkene cocurrently to a reactor;  withdrawing from the reactor a product mixture and effecting fractional distillation there-of;  withdrawing from such fractional distillation a product phase comprising the oxirane and a recycle phase comprising carboxylic acid in the chlorinated hydrocarbon, and passing such recycle phase from the distillation to the extraction device to form the organic phase therein.  The importance of the invention resides in the integration of the epoxidation step with that of the manufacture of the peracid, and in the fact that the carboxylic acid, sulphuric acid and chlorinated hydrocarbon solvent are all recycled.

The resonance thermometer of the invention includes an oscillator for detecting a resonance in a resonant material and a modulator for modulating the oscillation frequency of the oscillator at a low frequency. A first detecting detector formed as a lock-in amplifier with a short time constant detects with low accuracy a component from the modulated output of the oscillator causing a high speed sweep to be stopped.  A second detector formed as a lock-in amplifier with a long time constant them detects with high accuracy the component from the modulated output of the oscillator.  The output of the second detector, and the temperature is derived from the detected resonance-absorption frequency.

Abstract: METHOD OF AND APPARATUS FOR BREAKING BRITTLE MATTER          ABSTRACT OF THE DISCLOSURE      A cutting-chipping system comprising an interconnected triaxial array of rotating drums each mounted for independent rotation.  Each drum includes a plurality of spaced, outwardly extending teeth to sequentially cut, chip and break brittle mass such as coal or ice engaged by the system.  The drums are oriented with no axis of drum rotation parallel to another and in a configuration wherein the direction of cutter travel from one drum is oblique to that of a second drum.  In this manner, brittle matter engaged by the system is initially cut and chipped by a first drum to form a series of protuberances and/or weakened sections which, when struck at an oblique angle by a second drum, will chip and break away.  The teeth may be comprised of picks, chisels or combinations thereof constructed and adapted for bidirectional rotation. The system may be adapted for applications upon land vehicles, water crafts, floating platforms, and the like.  Variation in rotation velocity of the separate drums and/or opposing rotational directions thereof may then facilitate positional control of the system as well as depth and speed of cutting as necessitated by the particular application.
