Patent DE-2636701-A1 (DE)
Title: AC-heating of pipes using skin effect - suitable for pipes conveying heavy oil
Inventor: OTHMER DONALD F PROF
IPC: H05B6/10
Filed: 1976-08-14
Abstract: Device is for heating a long body, esp. a pipe, made of an electrically conducting metal with magnetic properties, and through which a medium flows. A long, insulated conductor is laid on the outside of the pipe, but is not magnetically screened from the pipe, and a.c. is fed through the conductor and the pipe. The a.c. produces a skin effect generating heat in the pipe which is directly transferred to the flowing medium. The conductor may be flat metal strip insulated on all sides; alternatively, an extra insulating shields may be located round the conductor where the shield butts against the pipe. One embodiment uses two conductor wires located in resistance material which has a positive temp. coefft of resistance (P.T.C) so current flow is reduced as temp. increases, i.e. the material acts as a thermostat. Used e.g. for the inexpensive heating and insulation of a steel pipe through which heavy oil is pumped.

Title: Self-cleaning electrostatic precipitator - cleaned by variable frequency vibrations produced by tank of compressed air
Inventor: CHENEY WILLIAM ALBERT
IPC: B03C3/76
Filed: 1977-08-19
Abstract: Two-stage electrostatic precipitator comprises an ionizer and a collecting cell through which air to be cleaned is moved. The contaminant collecting plates in the collecting cell are cleaned by a vibrator which applies vibrations of variable frequency to the supports on which the plates are mounted. The vibrations are produced using a tank of compressed air which empties while actuating the vibrator so that as the air supply runs down the frequency of vibrations emitted by the vibrator decreases. Operation of the precipitator is controlled through a switch having an off position at which both the ionizer and the vibrator are inoperative, an on position in which only the ionizer is operative and a clean position in which only the vibrator is opeative. Used for sepg. powder like particles of =1 mu from the atmos. for recovery and re-use if desired. Increased cleaning efficiency can be achieved because by varying the frequency of vibrations a greater area of the collecting plate is reached.

Title: Cylindrical rotor machine winding and excitation system - permits variation of magnetic axis without corresponding mechanical movement
Inventor: PERUNICIC STANKO
IPC: H02K19/36
Filed: 1977-08-23
Abstract: The rotor winding comprises several axially displaced coil assemblies (1) contained in slots around the rotor perimeter. Each coil assembly is fed from a variable voltage excitation power source (2) through slip-rings and brushes (3, 4). By cyclic and sequential variation of the excitation voltage of successive coils the flux axis can be moved around the rotor perimeter. When applied to a synchronous generator, the proposed rotor winding can be used to make the necessary change in flux axis following a load change in the machine output without involving a change in rotor kinetic energy. A more stable operating regime can thus be achieved.
