Abstract: An improved breathing devise, for use in the nasal passageways. This nasal breathing apparatus utilizes a flexible tube, that defines two centrally adjacent notches, spaced apart by a central tube portion. The terminating ends of the tube preferably have a portion of the circumferential tube removed, so that the ends define curved flanges. The section of modified tubing is bent approximately 90 degrees from the central portion, with the arcual outer surfaces of the tube ends being placed directly into the nasal passageways. The flexible tube will urge the nasal passageway walls apart, thereby increasing the overall diameter of said passageways. Airflow is not significantly restricted, due to the tubular configuration of the apparatus, which conforms to the nasal passageway shape it contacts. The central tube portion is capable of receiving an aromatic plug, which releases chemical substances adjacent to the nasal openings.

Abstract: The rotary engine is an expansion fluid turbine for supplying power to lawn mowers, small vehicles, electrical generators, and the like. Fuel and oxygen are supplied from bladder tanks to combustion chamber, while water is supplied to an annular sleeve surrounding the combustion chamber in a mist by a spray nozzle. Ignition of the fuel-oxygen mixture by a glow plug heats the mist to supply steam for turning a rotor. The rotor has a circular top plate with a plurality of pin diffusers depending from its lower surface, and an annular bottom plate with a plurality of pin diffusers attached to its upper surface. A swirl pan has a flange on which the lower plate seats, and defines a swirl chamber. The steam enters the swirl chamber through a bifurcated intake conduit. Swirling in one direction causes rotation, while swirling in the opposite direction causes braking.

Abstract: An electric bed heating device for attachment to the understructure of a bed for supplying heat to a sleeper includes an electric heating element mounted below a metallic plate thermally insulated on its upper side and having a lower face shaped to radially downwardly direct heat. In one embodiment the heating element is directly supported by vertical fins extending downwardly and radially outwardly from the lower face of the plate with the fins and heating element being exposed. In another arrangement a serially slit lower metallic plate is spaced below the first mentioned plate to allow flow of air therebetween. The lower plate supports an electric heating element in the path of the air flow. The slits in the lower plate form offset air inlet and outlet openings. The plates are aligned and attached to the bed structure by a central fastener binding the plates together. The upper face of the lower plate is roughened and blackened to enhance heat absorption.

Abstract: Benzotrihalides are prepared by pyrolyzing a substituted phenyl trihaloacetate of the formula ##STR1## wherein each X is halo, nitro, alkyloxy, aryloxy, aralkyoxy, cyano, lower alkyl, haloalkyl, haloalkyloxy, alkenyl, haloalkenyl, carbamoyl, N,N-dialkylcarbamoyl, N,N-diarylcarbamoyl, or N,N-diaralkyloxy;Y is halo; andn is an integer of from 1 to 5. As an example, 4-chlorophenyl trichloroacetate is pyrolyzed at 550.degree. C. to 4-chlorobenzotrichloride.

Abstract: Organic halides containing at least one halogen-replaceable bromine atom are reacted with chlorine in the presence of a catalyst selected from the group consisting of the halides of antimony, tin, zinc, or vanadium to form a corresponding organic halide having at least the one bromine atom replaced by a chlorine atom.

Abstract: A turbine in the form of an endless "Venetian blind" set of arcuate turbine blades mounted to extend between a pair of endless chains that are entrained over sets of sprockets so that two flights of the blades travel in opposite directions in closely spaced parallel planes. Shafts connect sprockets of the sets to maintain the blades parallel and to deliver to an alternator the torque applied to the sprockets by the reaction of the blades to a fluid passing therethrough.

Abstract: The rate of photochlorination of methyl aromatic compounds, such as toluene, cresol, xylene, toluenesulfonyl chloride, methylnaphthalene, diphenylmethane, etc., is increased when carried out in the presence of bromine.

Abstract: The title compound is made by the direct bromination of citraconic anhydride in the vapor phase at 200.degree.-500.degree. C. with a contact time of less than about 20 seconds. The reactants are preferably diluted with an inert solvent, such as a halogenated hydrocarbon and/or a gaseous diluent, such as N.sub.2.

Abstract: A new process for preparing .gamma.-halonitriles comprising reacting by contacting a 1,3-dihalopropane, such as 1-chloro-3-bromopropane, or mixtures thereof, such as 1-chloro-3-bromopropane and 1-chloro-3-iodopropane, with an alkali metal cyanide, such a sodium cyanide, in the presence of an onium salt, such as benzyltriethylammonium chloride, and an alkali metal halide, such as sodium chloride. The .gamma.-halonitriles are useful in preparing cyclopropylcyanide, a herbicide intermediate.

Abstract: Brominated pentaerythritols are prepared at reaction temperatures of from about 85.degree. to 135.degree.C. by reacting pentaerythritol with HBr in the liquid phase employing a solvent medium containing from about 0.8 to about 25 mole percent of an aliphatic carboxylic acid of 2 to 8 carbon atoms and their anhydrides, based on the pentaerythritol. The HBr is fed continuously to the reactor throughout the reaction. The water formed as a result of the reaction remains in the reaction mixture until substantial completion of the reaction. The product can be predominantly dibromoneopentyl glycol or tribromoneopentyl alcohol and is characterized by the absence of tar formation.
