Abstract: ELECTROSTATIC SPRAY GUN APPARATUS     ABSTRACT OF THE DISCLOSURE          A hand-manipulable electrostatic spray gun is dis-closed which is one requiring no electric cable attached to it.  Within the hand-manipulable spray gun an air turbine is driven at high speed in the order of 60,000 rpm and drives directly an alternator to generate an alternating voltage in the order of 50 volts at about 1000 Hz.  The output of this alternator is supplied to a step-up transformer to achieve a secondary voltage in the order of 2500 volts.  From here, it is supplied to a long chain series voltage multiplier to increase the voltage thereof to one in the order of 55-80 kilovolts.  The combination of a relatively small transformer and small capacitance establishes a direct voltage output from the voltage multiplier which has an alternating voltage ripple in excess of fifteen percent.  The foregoing abstract is merely a resume of one general application, is not a com-plete discussion of all principles of operation or applica-tions, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: Abstract The present invention is related to a surgical aspiration device for use in surgical operations, whereby the aspiration device is intended for use in atraumatic aspiration, tissue aspiration and dissection. The surgical aspiration device comprises a handle with an inner tube (4) and an outer tube (7) which extend from the handle (1) and which are arranged concentrically to the formation of an interstice between them. Adjacent to the handle (1) is an air inlet opening (9) which allows air inlet to said interstice (8), whereby when vacuum is applied to the inner tube for aspiration air passes into the interstice (8) and into the inner tube (4), whereby the aspirated liquid column is broken and atraumatic aspiration can take place.

Abstract: Abstract of the Disclosure A novel fixture and shade combination for fluorescent tubes is disclosed which permits rapid and easy insertion and replacement of tubes by having an opening in an end plate to permit the tube to be inserted from the end.  The shade defines separate chamber for receiving the fluorescent tube and transformer respectively and electrical conductors from the transformer to tube sockets in the tube chamber are mounted wholly within the tube chamber.  A plurality of spaced transverse cross-plates are located in the tube chamber, each cross-plate having a slot to permit the tube to pass through from the end, so that the whole tube is received within the chamber and, once so received, to permit the tube to be moved transverse to its axis to engage the sockets.  The fixture has a maximum height limited to the height of the shade requiring less space and its novel design permits simple and safe replacement of the fluorescent tube.

Abstract: ABSTRACT A process for producing a non-woven textile containing a bonding agent, and an adhesive on one side of the textile; in which the radiation polymerizable bonding agent is printed onto the textile from one side while the adhesive is printed on in the form of a powder by a powder-point or screen printing process from the other side.  The printed textile is then subjected to irradiation from a mercury vapour lamp of which about 10 to 30% of the radiation is in the ultra-violet region  for polymerizing the bonding agent. The remainder radiation serves to heat the material so that the particles of adhesive coalesce sufficiently to maintain their geometric shape distribution in the material.  The material is subsequently dried, finished and the adhesive sintered.  Using the screen printing process at least 95% of the particles in the powder are less than 0.1 mm in diameter, and using the powder-point process, 95% of the particles are less than 0.2 mm diameter.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for recovering zinc from zinc-contain-ing sulphidic material also containing iron and from zinc oxide containing material.  Zinc-containing sulphidic material is leached under pressurized oxidizing conditions at a temperature in the range of from about 130 to about 170°C in aqueous sulphuric acid solution with an initial stoichiometric excess of sulphuric acid relative to the zinc content of the sulphidic material to form a leach slurry containing dissolved zinc and iron.  The leach step is continued until a substantial amount of zinc has been dissolved from the sulphidic material.  Zinc oxide containing material is then injected into the leach slurry, while maintaining the pressurized oxidizing conditions and temperature to raise the pH of the slurry to a value in the range of from about 4.5 to about 5.5 to precipitate dis-solved iron and form an iron-containing residue and a rela-tively iron-free leach solution.  The residue is separated from the leach solution, and the leach solution is treated to recover zinc.

Abstract: RCA 76,854 ABSTRACT OF THE DISCLOSURE           A digital filter is provided which selectively employs straight binary arithmetic and offset two's complement arithmetic in an adder ladder to protect against signal overflows and underflows, as well as to minimize adder size.  Signal overflows and underflows are prevented by performing subtraction and certain additions in offset two's complement notation, while adder sizes are minimized by performing certain other additions in binary notation. In an alternate embodiment, positively weighted values are combined by binary addition in a first adder ladder, and negatively weighted values are combined by binary addition in a second, parallel adder ladder.  At the outputs of the two ladders, the two sums are converted to offset two's complement notation, and the negatively weighted sum is subtracted from the positively weighted sum.

Abstract: Abstract Of The Disclosure A wind powered device on a support structure is provided with a drive shaft mounted for rotation about its axis on the support structure and is coupled to an electric generator connected to a utility power grid.        A rotor is mounted on the support structure and is adapted to drive the shaft, hence the electric generator.  The rotor has at least one rotor blade.          The rotor is mounted to drive the shaft and also for limited relative rotational movement with respect to the drive shaft about the axis of the drive shaft as the wind velocity driving the rotor changes.  The coupling between the shaft and rotor responds to increases and decreases in rotor torque so that as imbalances between shaft torque and rotor torque arise, the rotor tends to run ahead of or behind the shaft.  That causes rotation of the rotor relative to the drive shaft and the coupling means sense that change and automatically increase or decrease blade pitch via the automatically responsive mechanical coupling means to tend to bring shaft torque and rotor torque back into balance.  Desirably the shaft is governed by a speed regulator, such as a generator connected to a utility power grid, so that it will rotate up to a predetermined speed or speeds beyond which shaft torque tends to increase sharply, so that if the speed of rotation of the rotor increases to a point at which it tends to exceed maximum permitted shaft torque, the blades are automatically increased in pitch which then decreases rotor speed, hence rotor torque.        Several embodiments for automatically mechanically adjusting blade pitch in response to changes in rotor torque and imbalances in rotor and shaft torque are disclosed.

Abstract: Abstract of the Disclosure A signal transmission system utilizes the electrical power distribution wiring of a building or house as the data transmission line.  Within the signal transmission system a detection system is required to detect the frequency component of the power distribution voltage.  The detection system includes a zero-crossing level detection circuit for developing a detect-ion output when each zero-crossing is detected in the voltage on the distrubution wiring.  A timer element is provided in the frequency detection system, which functions to cause the block-ing of an output signal from the zero-crossing level detection circuit for a preselected time period after each detection out-put, thus avoiding spurious output signals caused by noise.
