Abstract: Abstract of the Disclosure An electric motor drive, the operative condition of which may be remotely ascertained over telephone lines, includes energizing circuitry having a plurality of test points providing test signals.  A switch means has the input coupled to the test points and the output coupled to a signal generating means which generates audio tones in accordance with the characteristics of the test signals at frequencies suitable for transmission over the telephone lines.  The signal generating means is connected to a coupler at one end of the telephone lines and a converting means is connected to a coupler at the other end of the telephone lines.  The converting means converts the audio tone transmission signal into an analog electrical output signal which drives an indicating meter.  The couplers also provide voice communication over the telephone lines.

Abstract: ABSTRACT OF THE DISCLOSURE             A method of an apparatus for improving the capacity and efficiency of electrostatic precipitators by increasing the average field intensity. The precipitator is supplied with a substantially constant base level DC voltage that is less than the sparking thres-old level of the precipitator, and superimposed thereon is a period-ic DC voltage waveform of short duration having peak levels that substantially exceed the sparking threshold level. By controlling the characteristics of the periodic DC voltage waveform the av-erage applied voltage is greater that the sparking voltage but the duration of the instantaneously applied voltage is not sufficient to cause sparking in the precipitator.

Abstract: APPARATUS FOR STRIPPING AN ANODE BLOCK         FROM AN ANODE ASSEMBLY            ABSTRACT OF THE DISCLOSURE:         Apparatus for stripping an anode block, or butt, from an anode assembly used in aluminum smelting includes a conveyor having a carrier from which the anode assembly is suspended and a stripping station on the path of travel of the conveyor.  At the stripping station, the support of the anode assembly is transferred from the carrier to an anvil which is mounted in the path of movement of the anode as-sembly so as to be engageable by the yoke portion thereof. The transfer is accomplished by lowering the carrier and anode assembly on a lift section of the conveyor, stabiliz-ing the anode assembly against longitudinal and transverse swinging movements, and forwarding the carrier and the anode assembly along the lift section to a stripping position by a feeding device, the yoke of the anode assembly engaging an upwardly inclined ramp surface on the anvil during this forwarding movement and thereby transferring the weight of the anode assembly from the carrier to the anvil. A pair of pivoted stripping heads then move downwardly against the upper face of the anode block, stripping it from the yoke, and any portion of the anode block which still remains at-tached to the yoke is stripped therefrom by the anvil as the lift section is raised.

Abstract: ABSTRACT OF THE DISCLOSURE            There is shown an oil recovery apparatus and method which includes a plurality of like-sized disks carried on a rotatable shaft.  These disks are partially immersed in the fluid which contains the unwanted oil or oil like material to be removed or recovered from the larger body of fluid. The disks are preferably of plastic or are plastic coated and during immersion the oil contaminator is picked up by and with the engagement of the disks in the oil portion of the fluid after which plastic scraper blades engage the sides of the disks to remove this oil from the sides of the rotating disk.  The scrap-ings which are removed are fed by a channel guideway or ways to a collector.  Two arrangements of plastic scraper assemblies are shown.  In one embodiment there are two blades arranged to straddle the disk and simultaneously scrape opposite sides of this disk as the disk is rotated.  The removed oil is carried by two conductors to a collector.  In the other arrangement the scraper assembly carries a blade which extends outwardly to engage and scrape facing surfaces of two adjacent disks o The scraped oil is fed to a common conductor and then to a collector.  The scraper normally includes two plastic ribbon scraping portions, each of which are bent into a scraping angle as they are pressed into scraping engagement with a side of the disk.  The scraper units are readily removable from the collector apparatus for cleaning and/or repair and the strips of plastic which form the scrapers are readily and inexpensively replaced.
