Patent IT-1241431-B (IT)
Inventor: CASARO FAUSTO
IPC: F04D23/00
Filed: 1990-03-09
Granted: 1994-01-17
Abstract: A turbomolecular pump comprising, in addition to usual axial flow pumping stages consisting of alternated rotors (1,1a) and stators (2,2a), one or more tangential flow pumping stages (10;30) arranged at the exhaust side of the pump, to raise up the compression ratio. Each axial flow stage consists of a plane disk rotor (12;35) encompassed to a coplanar annular stator (13;36), spaced apart from the rotor disk, so that a free annular channel is formed in-between (14;38), in which channel the pumped gases move along a tangential flow. Such channel is closed by a baffle (15;39), and communicates with a suction port (17;40) and a discharge port (18;41). The plane disk rotor may be provided of vanes (37,37a,37b). It is possible to combine tangential flow stages (10) having rotor without vanes (12) and tangential flow stages (30) having rotor with vanes (35); in such a way it is possible to raise the exhaust pressure up to the atmospheric pressure, and to discharge directly in the atmosphere. <IMAGE>

Title: Recovery of components of slurries produced during metal milling - using filtration, solvent extraction and magnetic separation techniques
Inventor: TARICCO STEFANO
IPC: C10M175/04
Filed: 1978-03-10
Granted: 1985-11-18
Abstract: The slurries consist of metallic fragments, abrasive particles and an oily liq. used as a cooling agent during the milling. The process consists of mechanically separating the liq. from the solids by compression between two rollers; treating the solid with a solvent to clean away any residual oil; heating the solid in a reducing atmosphere and separating the ferrous from the nonferrous particles magnetically. The process enables the vast quantities of these slurries which are produced each day in industry to be treated so that the oil can be recycled and the metal particles used in the metallurgical industry. Pollution resulting from disposal of the slurries is avoided.

Filed: 1968-02-09
Abstract: 1,217,002. Coatings. DESOTO, Inc. 8 Feb., 1968 [10 Feb., 1967; 28 April, 1967], No. 6271/ 68. Heading B2E. [Also in Divisions C3 and C7] An electrically-conductive body is coated with a resin by immersing the body in an aqueous dispersion of a hydrophilic resin having an acid number of 8 to 70 and being a linear resin containing carboxyl groups and hydroxyl groups, the latter having been formed by reaction of some of the carboxyl groups with an epoxide and being positioned remote from the backbone of the resin, the resin being in the form of a salt with a base to provide dispersed particles of size less than 0.5 micron, passing a unidirectional current through the dispersion with the body as anode to form a film thereon and baking the film to cure it. The dispersion may also contain a waterinsoluble thermosetting aminoplast resin. The hydrophilic resin may be derived from a polyhydric polyether or an addition polymer. The polyether is preferably an aliphatic polycyolic polyether of the formula where n is 10 to 14. This is partially esterified with a monocarboxylic acid and the hydroxy ester is then reacted with a polybasic acid anhydride to provide carboxyl groups without cross-linking the resin. The product is then reacted with an epoxide in stoichiometric deficiency to form a hydroxy ester containing carboxyl groups. The epoxide is preferably a mono-epoxide but may comprise additionally or solely a polyepoxide, e.g. a diglycidyl ether of bis-phenol. The polyether may also comprise, instead of the above polycyclic compounds, glycidyl ethers of aromatic compounds or of glycols. The addition polymers which may be used are copolymers of hydroxyl-containing ethylenic compounds and carboxylcontaining ethylenic compounds. The first group includes hydroxyalkyl acrylates, methacrylates, maleates, crotonates and norbornene and alkyl, methalkyl and orotyl alcohols. The second group includes acrylic, methacrylic, crotonic, itaconic, maleic and fumaric acids and monobutyl maleate. The copolymers are reacted with epoxides as above. The aminoplast resin may be a urea-, melamine- or benzoguanamine-formaldehyde condensate in amount up to 40% by weight of total resin. A pigment, e.g. TiO 2 , and organic solvents may also be present. The base which may be used to convert the resin to a salt may be ammonia but is preferably an amine. The dispersion preferably contains 5 to 15% solids and may be maintained at a pH of up to 10. Voltages of at least 200 are suitable. In Example 1, a metal tank serves as cathode and steel and aluminium panels treated with zinc phosphate are used as the anodes for coating. The voltage is run up from zero to 500. The film is baked at 400‹ F. to cure.

Abstract: 1,240,880. Brushless motors. AKAI ELECTRIC CO. Ltd. 6 Aug., 1968 [8 Aug., 1967], No. 37404/68. Heading H2A. Star-connected phase windings L1, L2, L3 forming the stator of a permanent magnet rotor motor are energized from a D.C. supply through transistors Tr2, Tr4, Tr6 which are connected in a ring oscillator circuit 10, supplied through voltage and current control circuits 12, 11, and are rendered conducting by the voltage induced in successive windings. Each stage of the oscillator comprises two directly coupled transistors Tr3, Tr4 having the collector of Tr4 connected to phase winding L2. The input to the stage is coupled to the output of the previous stage through capacitor C1 and integrating circuit R4, C4 and similarly for the other stages. In operation the voltage across resistor R10 will alter with supply fluctuations and this voltage will be transmitted to base of transistor TR7 through VR and will set a voltage at one end of Zener diode ZD. Voltages at the ends of the phase windings will be rectified by diodes D1, D2, D3 and are applied to the other end of ZD and can thereby produce a current flow in resistor R10 thus causing the conductive state of TR8 to change. This charge in voltage will also occur when rotor speed changes and thus the circuits 11 and 12 act to maintain a constant rotor speed. The speed of the motor is varied by altering VR and switch SW2 is used to by-pass the current control circuit 11 so that a higher speed can be obtained.
