Abstract: HYDROLYSIS OF 3,5-DIAMINO BENZOIC ACID   TO PRODUCE ALPHA-RESORCYLIC ACID                    A B S T R A C T            Alpha-resorcylic acid is produced by the hydrolysis of 3,5-diamino benzoic acid in an aqueous solution of ammonium bisulfate.  The reactants are contacted at an elevated temper-ature for a period of time sufficient to hydrolyze the 3,5-diamino benzoic acid to alpha-resorcylic acid and the alpha-resorcylic acid so produced is separated from the reaction mix-ture.  The ammonium sulfate is regenerated to ammonium bisulfate by removing the water and thermally decomposing the by-product ammonium sulfate at an elevated temperature.

Abstract: ABSTRACT OF THE DISCLOSURE           A smoke detector of the type utilizing a photo-respon-sive device to detect light reflected from smoke particles illu-minated by a light source and actuate an alarm, in which a second photo-responsive device is utilized to control the intensity of the light source so that it is continuously exposed to a light intensity from the light source such that its thermal co-efficient of resistance is maintained at a value substantially equal to that of the first photo-resistive device when said first photo-resisti-ve device is exposed to the amount of light that causes an alarm.  In one embodiment of the invention identical photo-cells are connected into circuitry which includes two level detectors with the same transfer curve and voltage gain, and means causing the two photo-responsive devices to have the desired resistance at the alarm point. Changes in ambient temperature and line voltage are therefore prevented from affecting the alarm point.          In another embodiment of the invention the second photo-responsive device views the light source from a distance such that interven-ing smoke particles reduce the amount of light falling thereon, and thereby causes an increase in the intensity of the light source.  Smoke having a low reflectivity and high obscuration such as black smoke therefore causes an increase in output of the light source to thereby increase the amount of light reflected there-from.

Title: Flame retardant fibers
Inventor: ROSENTHAL ARNOLD J
IPC: D06M101/06
Filed: 1976-02-02
Granted: 1980-09-02
Abstract: FLAME RETARDANT FIBERS             Abstract of the Disclosure An assemblage of fibers is provided which exhibits highly satisfactory flame retardant characteristics in spite of the fact that discrete fibers are included within the admixture which would normally burn when exposed to flame.  Included in intimate physical admixture with the fibers which would normally undergo combustion are discrete additive fibers consisting primarily of a chlorinated and/or brominated aromatic polymer having the inherent ability to render the admixture as a whole non-burning when subjected to the flame.  Particularly preferred additive fibers are formed primarily of an aromatic polyester formed from the reaction of tetrabromo-bisphenol A, isophthalic acid, and terephthalic acid or the ester-forming derivatives thereof.  Also, in a particularly preferred embodiment a minor concentration of an oxide of antimony (e.g. antimony trioxide or antimony pentoxide) is intimately dispersed throughout the additive fibers.  Flame retardant fiber blends readily may be formed without a diminution of the textile properties thereof, e.g. hand and aesthetic appeal.

Abstract: AN IMPROVED PRESELECTOR CAVITY ARRANGEMENT         AND RF SELECTIVITY ASSEMBLY     ABSTRACT     An improved preselector cavity arrangement and RF selectivity assembly includes a cast housing for the prese-lector with a plurality of interconnection apertures or slots, each being surrounded by a boss.  Each boss is mated with a slot in an adjoining housing of an interconnected module for allowing input, output and injection connections to be made to the preselector without intermediate connections to the supporting printed circuit board.  One adjoining housing may contain the RF amplifier with coupling and impedance matching to the amplifier output coil provided by a loop from the preselector input.  The loop passes through the shielded aperture, couples to the output coil by passing around the coil form and then returns to ground on the preselector casting.  The injection filter and tripler/ mixer modules may be contained in other adjoining housings and also coupled to the preselector through shielded apertures.          To minimize RF spray radiation no interconnections are made via the printed circuit board.  All possible area on the board underneath the housing arrangement is plated and grounded to act as a Faraday shield for further reduction of RF spray radiation.  The mating side of the preselector housing includes tabs which complete the shielding of the two end access slots when the side is soldered into place.          A strap is soldered across the tops of the separate shields to complete the shielding effect.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of extracting oil from an underground bed of an oil bearing mineral.  The method comprises introducing a plurality of conduits into a first, lower part of the bed.  Each conduit is spaced from its neighbours and includes a relatively course filter at its lower end and contains a relatively fine filter and a lift pump.  A first conduit of the plurality of conduits extends to a depth less than the depth of its neighbours.  The pressure in the first conduit is reduced.  A solvent for the oil is introduced into those conduits at ambient pressure so that the solvent is drawn towards the first conduit and forms a flow path in the bed as it is drawn to the first conduit.  The oil-solvent solution is pumped from the first conduit and the space left in the first area after extraction of the oil is filled with water.  The conduits are raised to a second, higher part of the bed when all oil has been extracted from the first lower part and the flow direction is recovered by having the first conduit extend to a depth greater than the depth of its neighbours and reducing the vacuum in the neighbours.  Oil and solvent are pumped from the neighbours.  The conduits are successively raised and the flow direction changed for successive, higher parts of the bed.
