Abstract: Abstract An air cleaning method and apparatus is dis-closed in several embodiments.  In one set of embodiments, there is described an air cleaning method and apparatus in which air to be cleaned is drawn toward and through a fil-ter  in  a particular  direction.   Periodically,  reverse pulses of air are directed through the filter in a direc-tion opposite to normal flow to interrupt the flow of air and to dislodge collected particles from the uncleaned air side of the filter and to enable migration of the par-ticles toward the downstream lower end of the filter.          In  accordance  with  other  embodiments  of  the present  invention,  there  is  described the  addition of inertial precleaner devices located proximate the unfil-tered side of each filter for inertially separating heavy particulate matter from the uncleaned air prior to filtra-tion.  In addition,  the inertial precleaner devices may have closure means operable during the periodic reverse pulse cleaning to remove the dislodged collected particles and prevent reentrainment on the filter.

Title: Method and apparatus for automatically controlling travel of two plastics film strips as a bag material or the like

Granted: 1983-12-20
Abstract: ABSTRACT OF THE DISCLOSURE           This invention provides an improved method and apparatus for automatically controlling travel of two trans-versely spaced parallel plastics film strips,which are intermittently moved, to maintain transverse alignment between register marks on the two film strips in a bag-making machine or the like that can correct rapidly and effectively the relative positional gaps produced between the register marks on the two strips by means of a single retarding device for the two strips as incorporated in the apparatus.  The single retarding device is arranged to constantly and relative-ly impart a retarding force to the two strips and to operate such that when the retarding force imparted to the preceding strip is stepwise raised to further slow either one of the two strips that goes ahead of the other strip, the retarding force imparted to the other lagging strip is stepwise lowered and released, conversely to thereby accelerate advance of the other lagging strip relative to the decelerating preceding strip, whereby said relative positional gaps can be rapidly and effectively corrected.

Abstract: ABSTRACT OF THE DISCLOSURE           A receiver for a compatable stereophonic television sound transmission system having left and right audio signals in conjunction with a television broadcast wherein video information is conveyed on an amplitude-modulated carrier in a frequency channel having defined frequency limits.  The system includes at a transmitter location a multiplex generator for generating a composite signal having a first component representative of the sum of the audio signals, a second component comprising an amplitude-modulated suppressed carrier subcarrier signal representative of the difference between the audio signals, and a pilot component representative of the phase and frequency of the suppressed carrier.  The composite signal is utilized to frequency-modulate a sound carrier to develop an RF signal component which is added to the television channel at a discrete frequency spacing from the video carrier.  The receiver includes a tuner for converting the transmission channel to an intermediate frequency, a filter for separating the sound signal therefrom, and a detector for deriving the composite signal from the sound signal.  The composite signal is demodulated in a stereo demodulating stage to develop the left and right audio signals.

Abstract: Abstract of the Disclosure Disclosed is a static reactive power compensator connected to the secondary winding of a power transformer.  The compensator is formed of a parallel connection of fixed cap-acitors  individually connectable to the power line and of thyristor-adjusted inductors, a booster transformer having phase-varying secondary windings being connected between the secondary winding of the power transformer and the thyristor-adjustable inductors.  With this arrangement, the capacitors can be connected singly with little effort without a 6-pulse reaction occurring on the power line, and without the capacitors being loaded via harmonic currents of the 5th and 7th order.

Abstract: Abstract of the Disclosure A single mode optical waveguide is constructed in a manner such that the core thereof is subjected to a stress-induced birefringence.  In accordance with one embodiment the fiber comprises an oblong core surrounded by an oblong inner cladding layer.  An outer layer of stress cladding glass, which has a circular outer surface, surrounds the inner cladding layer.  The TCE of the stress cladding glass is different from that of the inner cladding glass.  In another embodiment the stress-induced birefringence is accomplished by introducing into the cladding region of the fiber on opposite sides of the core longitudinally extending regions of glass having a thermal coefficient of expansion different from that of the remainder of the cladding.  A number of novel techniques are disclosed for forming such fibers.

Abstract: Abstract So that the freight or storage tank for bulk material, that has at least one long emptying hole on the bottom, can be closed and opened, the tank has at least one flexible belt that extends essentially over the length of the opening and whose one end is attached to the tank, and under which is a roller or roller system that is approximately of the same length and that supports the belt when in the closed position and that can be removed from the closed position, as well as elements to move the roller or roller system across the opening between two extreme positions. Elements that guide the roller or roller system between the said two extreme positions by way of the top dead center and operating elements that force the roller or roller system over the said top dead center are fitted onto the tank's frame so that the opening is closed more firmly the greater the tank's load and so that the load's weight is used in opening the opening and so that a loosening effect upon the tank's contents is achieved when the opening is opened.

Abstract: In a process of gaseous opalization a film of silica is formed by an oxidation reaction with a dry gas containing oxygen. Pure oxygen or oxygen diluted in an inert gas, other than nitrogen, may be used. An electric arc is generated by an alternating voltage between 5,000 and 10,000 volts and is directed at a chlorinated silicon compound, entrained by the dry gas containing oxygen, the feeding of which gas carrier does not form silica on the electrodes which generate the arc. This process may be applied to the opalization of incandescent and discharge bulbs of various sizes including tubes and globes of lighting apparatus.
