Patent GB-2459063-A (GB)
Title: Air conditioner
Inventor: IKEDA TAKASHI
IPC: F24F1/0063
Filed: 2008-02-20
Abstract: An air conditioner exhibiting high product reliability and transportability during transportation, not imposing a sense of oppression to a resident because of low noise, and being packed in less packing material as compared with conventional one. A centrifugal fan mounted on an air conditioner is shaped to have the following relation; the outside diameter of the side plate of the centrifugal fan > the side plate side outside diameter at the trailing edge of the blade > the main plate side outside diameter at the trailing edge of the blade >= the outside diameter of the main plate. The trailing edge of the blade is located on the inside of a line, which connects the joint of the trailing edge of the blade to the main plate, and the joint of the trailing edge of the blade to the side plate when viewed from the axis of rotation, and a distance to the axis of rotation becomes longer from the main plate toward the side plate.

Title: Improvements in or relating to regulator devices for adjustable blade propellers
IPC: B64C11/30
Filed: 1940-06-08
Abstract: 544,580. Reciprocating pumps. BLANCHARD, W. J., and MACNEIL, C. S. J. June 8, 1940, No. 10061. Convention date, June 16, 1939. [Class 102 (i)] [Also in Groups XXXIII and XXIX] A self-contained regulator for adjustable propellers comprises a pump and associated regulator or valve both rotating with the propeller, the regulator valve which controls application of pump fluid pressure for blade adjustment being responsive to the speed of rotation and subject also to an opposing spring force the strength of which may be varied. According to the invention the pump and regulator valve are disposed in a sealed housing containing the operating fluid, the fixed pumpactuating member engaging the pump during its rotation to develop pressure which is used for blade adjustment determined by the setting of 'the regulator valve in. accordance with the control of the opposing force thereon by external means operated by the pilot. Arranged in radial fashion around a housing enclosing the regulator parts are the inlet valve chamber 48, Fig. 4, the pump valve suction chamber 60 and the pump chamber 61. Operating fluid contained in the housing is thrown outwards and centrifugally and is picked up by a funnel 45 for transfer through a part 47 to a chamber 48 provided with a cut-off valve 49 which is impelled outwards by centrifugal force as well as by the spring 50 and is loaded in the opposite direction by the fluid pressure in the chamber 52 which is in communication with the pressure side of the pump. The valve is closed on the attainment of a predetermined pressure.. A safety disc 55 ruptures should the valve fail to act on the attainment of the prescribed pressure. The spring returned piston 65, Fig. 6, is operated through a roller 70 by a cam-surface 27 mounted on a fixed member of the equipment. The pump cylinder port 75, Fig. 4, leads directly to the pump valve chamber 60, Fig. 7, including the suction chamber 77 and discharge chamber 84 with interposed valves 80, 86 controlling ports 78, 83 in members 76, 82. The valve 102, Fig. 2, which controls the position of the propeller blades is connected up by suitable ducts on the one hand with the suction chamber 77 and on the other hand with ducts leading to the propeller blade roots. The centrifugal force acting on the valve body 102 is balanced by regulator springs 126, Fig. 3, attached to a stirrup member 124. Variations in engine speed from a datum speed cause, under centrifugal action, inward and outward radial movements of the valve body 102 dependent upon the rate of such variations and resulting in adjustment of the propeller pitch until the engine speed is brought back to normal. The position of a roller 123 on a lever 118 determines the datum speed and this position may be adjusted from the cock-pit of the aircraft. Specification 545,520, [Group XXXIII], is referred to.

Title: Improvements in or relating to the separation of polymerized condensation products of phosphorus oxychloride with ammonia
IPC: C01B21/082
Filed: 1955-04-06
Abstract: Polymerized phosphorylamide is precipitated from a mixture of polymerized phosphorylamide and ammonium chloride (which is obtained by passing ammonia into a solution of phosphoryl chloride in an inert solvent at below 100 DEG  C. until at least 5 mols. of ammonia have been absorbed per mol. of phosphoryl chloride, and heating to above 100 DEG  C. but below 150 DEG  C.), by dissolving the mixture in water and adding an acid, e.g. sulphuric, hydrochloric, or nitric, or a water-soluble metal salt, e.g. magnesium, an alkaline earth metal such as calcium or barium, or a heavy metal, e.g. copper or lead, in aqueous solution.  The ammonium chloride solution is filtered off and may have 10-20 per cent methanol added thereto to precipitate further polymerized phosphorylamide.  The reaction mixture may be dissolved in just sufficient water and sulphuric acid added, or may be dissolved in dilute sulphuric acid.  The polymerized phosphorylamide may be recovered from the precipitate with acid by treating with a solution of hydrous ammonia and methanol, when the product is free from acid and has a pH above 7.  The precipitate obtained with a metal salt may be treated with an aqueous solution of ammonium carbonate, when the polymerized phosphorylamide is found in the solution and may be recovered by addition of methanol.  The precipitates may be used as insecticides and fungicides or the regenerated polymerized phosphorylamide may be used for flameproofing cellulosic materials.

Title: Improved manufacture of amino-aldehyde adhesives
IPC: C09J161/20
Filed: 1946-04-03
Abstract: A process of making an aqueous adhesive extended with wheat flour and having a pH between 2.5 and 6 comprises mixing wheat-flour with a urea- and/or melamine-formaldehyde condensation product, or the reactive constituents from which the condensation product is later to be formed when the adhesive is to be used and a water-soluble bisulphite in a concentration of 1-6 per cent based on the wheat flour.  About 50-250 parts of flour to 100 parts of condensation product may be used.  The bisulphite may be added at any stage before addition of water, and excess is not objectionable.  Catalysts, buffering agents, hardeners and accelerators, and modifiers such as thiourea, phenol, resorcinol, soluble blood albumen and the like (as such, or as resinous condensation products with aldehydes or coreacted with the amino-aldehyde resin) may be added.  The adhesive may be used in hot or cold press methods, in the latter case with the addition of acid catalysts preferably after mixing the flour, bisulphite, and water.  In examples: (I) spray dried urea-formaldehyde adhesive resin, sodium bisulphite, flour, and water were mixed in a glue mixer to form an adhesive of pH 4.5.  (II) An aqueous composition of finely ground dimethylol urea, flour, sodium bisulphite, oxalic acid and water was mixed to form an adhesive of pH 5.1. Alternatively, the dimethylol urea is dissolved in part of the water at 180 DEG  F. and the other ingredients then added, followed by cooling to precipitate fine particles of dimethylol urea.  A further method is to use coarse dimethylol urea in the mixture which is then made smooth by passage through a gear pump.  (III) An adhesive of pH 4.2 for hot pressing comprises a mixture of urea, formalin, flour, sodium bisulphite, oxalic acid, and water. (IV) Dry powdered melamine/formaldehyde adhesive resin, sodium bisulphite, flour and water is mixed to form an adhesive of pH 5.5, better results being obtained at pH 5.5.  (V) An adhesive of pH 5.5 or 4.2 comprises a mixture of finely ground melamine, formalin, flour, sodium bisulphite, oxalic acid, and water.  (VI) Urea, melamine, formalin, flour, sodium bisulphite, oxalic acid and water are mixed to form an adhesive of pH 5.5 or 4.2.  The melamine of the examples may be substituted by up to 25 per cent of blood albumen.  The compositions may be prepared as mixtures containing the resin with flour or formalin, formalin or flour, as the case may be, being added by the user to complete the process.  The Specification as open to inspection under Sect. 91 states that the condensation product may be modified with furfural and acetaldehyde.  This subject-matter does not appear in the Specification as accepted.
