Granted: 1981-11-03
Abstract: Abstract of the Disclosure The invention relates to a method for the currentless catalytic precipitation of aluminum.  The surface of insulating and conductive materials (substrates) to be aluminized is catalyzed, while a film-forming moisture-insensitive layer is developed, with a compound active at the boundary surfaces, by a brief immersion on a dilute solution of a modified ester or acylate of titanium, zirconium or vanadium, substituted at the metal atom with short- and long-chain organic radicals or a chloride of the transition metals of the IV and V secondary group of the periodic system of the elements and a water-containing metal soap of a polyvalent metal, preferably aluminum soaps; is intensively rinsed with aprotic solvents, preferably having a boiling point of over 100°C; and is immersed in a 1 to 4% solution of trial-kylaminalanes in a solvent mixture of aromatic and highly viscous aliphatic compounds.  A homogeneous and strongly adhering aluminum coating is thereby obtained.  Insulating and conductive materials and components, e.g., electronic components and reflectors can in this manner be homogeneously coated with strongly adherent aluminum.

Title: Radio telephone system

IPC: H04B7/12
Filed: 1977-10-06
Granted: 1978-09-26
Abstract: ABSTRACT           A portable duplex radio telephone system includes base station transmitters having a predetermined base transmission range, and a plurality of portable or mobile units each having a predetermined maximum transmission range shorter than the base transmission range.  Satellite receivers are deployed about each base station for receiving transmission from the portable units.  The base station transmitters transmit signals on a signalling channel and on at least one communications channel.  The portable receivers have means for scanning the base station transmitter signalling frequencies and for tuning to the signalling frequency associated with the strongest signalling signal received from the base transmitter. When communication is initiated, the portable transmitter and receiver are automatically retuned to one of the communications channels as determined by the strongest received signalling frequency and by channel availability.  Means are also pro-vided to continuously locate a portable unit and switch the operating frequency thereof as the portable unit moves between base station transmitter coverage areas.  Further means are provided to reduce the output power of each portable transmitter to the minimum satisfactory level in order to reduce battery drain and interference.

Title: Chlorotrifluoroethylene containing polymer  diaphragm
Inventor: BALKO EDWARD N
IPC: C25B13/08
Filed: 1977-11-17
Granted: 1982-09-07
Abstract: ABSTRACT OF THE DISCLOSURE           Fibers about micron size in cross-section of certain fluorine-containing polymers can be treated after being deposited as a diaphragm, either during operation or separately before installation, so that they develop a 0.25-millimeter-thick ply on either side of a central body which is substan-tially different in chemical composition.  This yields a diaphragm 1 to 5 millimeters thick which has a Mullen burst strength approximately three to five times greater than that of an untreated diaphragm (20-25 pounds per square inch versus 5 to 7 pounds per square inch) and a remarkably improved service life in the treated diaphragm (200 days and up) in comparison with such untreated diaphragm (30 days or less).  A polymer based upon a major proportion of chlorotri-fluoroethylene can be used.  This discovery is economically significant, in that it is an essential element in the technology of the replacement of asbestos diaphragms now used with a synthetic material.  Health-hazard and pollution-control considerations have made it desirable to replace asbestos, and this invention provides the key to the solution of the problem. Moreover, a synthetic-polymer diaphragm has two significant advantages that an asbestos one lacks it will withstand washing or cleaning with an acid solution, and it does not swell in service and resists erosion, so that a closer electrode spacing can be used and the cell voltage can thus be lower.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for conveying particulate material of the type wherein it is desired that the material be simultaneously pre-compacted from a generally loose state to a more or less solid "plug" state.  A screw conveyor is arranged to deliver loose particulate material to an intermedia? chamber at the end of the screw conveyor means wherein the material is pre-compacted by the action of the screw conveyor. Following the intermediate chamber, a piston reciprocating coaxially with the screw conveyor further urges the material in a direction coaxial with the centreline of the screw conveyor to further advance the material through a straight coaxial conduit within which the material becomes compacted to an increased degree of compactness, solely by the action of the reciprocating piston.  The reciprocating piston has an annular face, whose outside diameter is generally the same as that of the Industrial Design of the conduit. The second, high degree of compactness is thus achieved solely by the action of the piston.  Accordingly, the mounting of the screw conveyor is not subjected to extreme forces.  The device is capable of compacting, for instance, fibrous material of a relatively low fibre shear strength to an extemely high compactness without exceeding the fibre shear limit in the area of the screw conveyor.  Frictional drag in the conduit following the apparatus may be increased by vanes protruding inside of the conveyor.  The depth of the friction increasing vanes may be selectively adjustable.
