Abstract: Abstract A power supply provides high voltage for a grid con-trolled x-ray tube.  In the supply an oscillator generates a high frequency signal which is amplified and transformed to kilo-voltage.  A voltage multiplier increases the kilovoltage to a potential suitable for the tube.  The voltage multiplier in-cludes a bank of series capacitors which tends to maintain a constant high voltage when the tube is not conducting.

Abstract: ABSTRACT OF THE DISCLOSURE:          The invention is concerned with a process for sepa-rating and recovering organic compounds from oxygen-containing recycle gas deriving from the ozonisation of mono or poly-unsaturated compounds, in the presence or absence of solvents. The gas before being recycled, is subjected to the following treatment: (a) passage through a suitable apparatus in which the products contained in the gas in the form of fumes are separated; (b) countercurrent scrubbing with a polyoxyalkylene-glycol having a molecular weight of 200 to 10,000 and pretreated with an anhydride of a monocarboxylic acid containing 2 to 4 carbon atoms; and/or (c) countercurrent scrubbing with a polyoxyalkyleneglycol having a molecular weight of 200 to about 10,000 or with an excess of a basic compound of an alkali metal in the form of an aqueous solution a Ph ? 8.  The organic compounds absorbed during treatment (b) are then recovered by stripping at atmospheric pressure or under vacuum. If only treatment (c) with the polyoxyalkyleneglycol is carried out, the compounds are subsequently recovered either by strip-ping at atmospheric pressure or under vacuum, or by hydrolysis followed by distillation at atmospheric pressure or under vacuum.  The process of the invention makes it possible to treat large quantities of gas with small quantities of scrubbing liquid, therefore attaining low stripping costs.

IPC: H04L25/00
Filed: 1979-08-28
Granted: 1982-06-01
Abstract: ABSTRACT OF THE DISCLOSURE      A data transmission path comprises a first and a second station, a first data transmission channel operative for synchronously trans-mitting data from the first to the second station in synchronism with a predetermined clocking schedule and at a respective first maximum data transmission rate, and a second data transmission channel for asynchronously transmitting data from the second to the first sta-tion at a respective second maximum data transmission rate, the first maximum data transmission rate being equal to a multiple p of the second maximum data transmission rate.  A test waveform is applied to the first station for transmission to the second station along the first data transmission channel, the test waveform presenting a data transmission rate at least approximately equal to said first maxi-mum data transmission rate.  A test waveform, as received at the second station, is applied to a selector circuit whose output wave-form is applied to the transmitting input of the second station for transmission back to the first station along the second channel.  The selector circuit transmits to its output only every p-th one of the waveform elements applied to its input, relying on clock signals which the second station produces one per waveform element of the synchronously transmitted test waveform.  The shortest waveform-element duration of the waveform produced at the output of the se-lector circuit at least approximately corresponds to said second data transmission rate.

Abstract: EXCITATION COMMANDING FOR CURRENT FED MOTOR DRIVES                     ABSTRACT OF THE DISCLOSURE             An a-c electric induction motor control system having apparatus for balancing motor air-gap flux against motor stator current in a manner to derive a motor excitation command signal which tends to cause the control system to force the motor to operate  on a predetermined torque versus slip frequency characteristic. The motor excitation command signal is utilized to regulate the magnitude of excitation supplied to the motor such that the air-gap flux level assumes a predetermined magnitude as a function of the motor slip frequency. Above motor corner point velocity, the balancing is modified in favor of flux such that the motor is operated in a constant horsepower mode. ]

Abstract: MAGIC PICTURES     Abstract of the Disclosure The present invention relates to a "magic" coloring package combination consisting of magic pictures and a felt tip marker pen filled with water or containing a water solution therein.  These magic or invisible coloring pictures consist of printed papers which have various figures outlined in a dark color, e.g. black, wherein the space within the figure is printed with a uniform water insoluble ink including therein one or more latent water soluble coloring materials which may be printed in a pattern of dots.  When the insoluble imprints of ink are contacted by the felt tip, the water in the pen is deposited on the paper and releases the latent coloring material, thereby spreading it on the adjacent locality of the paper.  This magic coloring combination is designed to be used by a small child on a trip, e.g. airplane ride or a car, where water is either unavailable and/or would be too messy to utilize.          The present invention also relates to a felt tip pen filled with or containing a water solution and designed to activate the latent coloring materials on a so-called "magic" picture.

Abstract: ABSTRACT A process for the production of a compound body comprising a thermally cured flocked foam plastic layer secured to a porous carrier strip.  The foam is applied to the strip in uncured form, and flock fibres are applied to the foam.  The flocked foam upon the carrier strip is passed through a heating tunnel to cure the foam and the cured foam and carrier strip are passed through n heated roller press or plate press.  The foam in its uncured state has a consistency such that it superficially penetrates the porous carrier strip but does not penetrate it completely.  By this process it is possible to obtain an exactly reproducible structure even though the treatment takes place with heated pressure rollers or pressure plates after passage through the heating tunnel.  Further, it has been shown that it is possible to obtain a product that to a very large extent is easy to handle and can be adapted to complex surfaces.

In one embodiment, the brake disc is secured to the carrier at its outer periphery by a plurality of circumferentially spaced bolts. In two other embodiments, the brake disc is mounted for limited relative movement with respect to the carrier to accommodate radial and circumferential thermal expansion and contraction in aggravated situations. In one of these other embodiments, the brake disc is retained against excessive circumferential movement relative to the carrier by a plurality of individual lugs affixed to the carrier.
