Abstract: ABSTRACT OF THE DISCLOSURE        The invention is an improved process for the manufacture of vinyl chloride from ethylene dichloride. Specifically, the invention is an improved process for the catalyzed dehydrohalogenation of ethylene dichloride in the presence of oxygen and a catalyst comprising a rare earth metal chloride on a zeolite.  The process enables one to conduct the dehydrohalogenation (or cracking) operation at significantly lower temperatures than employed using a thermal process, without the coking problems observed in such cracking processes.

Abstract: ABSTRACT         Integral, elongated panels have sets of flanges arranged on lines which define folded, transversely triangular elements.  These elements extend laterally across the panel, and are dimensioned such that a pair of adjacent parallel side edges of two corresponding panels can mate.  The flanges preferably extend along the entire length of the lines defining the folded transversely triangular elements, and may usefully be linear and arranged on lines defining congruent elements with triangular faces, and sloping side edge portions of the panel.  By such arrangement, a panel is obtained which in conjunction with other such panels, can produce a curved surface, which curvature may be reversed in direction in any point along a structure surface, by inverting the next adjacent series of panels.

Abstract: TITLE         REMOVING NEUTRON-ABSORBING FISSION PRODUCTS FROM URANIUM-BASED FUELS                          INVENTORS                Bradley J.F. Palmer Christopher H. Knight ABSTRACT OF THE DISCLOSURE         Nuclear fuel comprising uranium and containing neutron-absorbing  fission  products  due  to  irradiation,  can be  processed to remove such fission products by contacting the fuel in a comminuted form with a weak acid or a solution of a weak acid selected to preferentially dissolve  these  fission products,  and separating the acid solution from the comminuted fuel.   This treated fuel having reduced levels of  neutron-absorbers  can  be  reconstituted  and  recycled  to yield higher burn-up of fissionable components.  This treatment is particularly suitable for recycling irradiated enriched fuel in a tandem fuel cycle.

Abstract: Abstract of the Disclosure A digital microwave radio repeater using the same carrier frequency for the transmitting and the receiving carriers for improving the frequency utilization efficiency.  The transmitter-to-receiver interference signal is cancelled by producing an estimated-interference signal of the interference signal from the digital baseband signal by the use of a transversal filter and by subtracting the estimated-interference signal from the received signal.          The estimated-interference signal is also produced by frequency shifting a digital modulated signal in the transmitter.  The transmitting carrier frequency is locked to the receiving carrier frequency by the use of a phase-locking technique, so that the interference signal is reduced.

Abstract: INTEGRATED MESSAGE SERVICE SYSTEM            Abstract This integrated message service system provides a user both with an indication of which of a plurality of message service systems contain unretrieved messages and access to these unretrieved messages.  This is accomplished by the serving telephone switching system maintaining a translation memory that indicates both the type of message services assigned to each user and the locationof unretrieved messages in the assigned message services.  The translation memory is updated every time a user creates a new message or accesses a previously stored message.  The serving telephone switching system forwards all unretrieved messages from all the message service systems to a user when the user has accessed any one of the message service systems.  This eliminates the need for a user to access all assigned message service systems to retrieve messages.

Abstract: ABSTRACT            The soil loosening device has at least one, preferably two journals protruding downwardly from a supporting body, which are driven to a pivotal motion along a limited angle. Tine-like soil loosening tool members in bifurcate arrangement, to be driven along a circle segment, are mounted on the journals. The driving unit for driving the tools is characterized by its simple design since it consists of only a few, reliably guided and sturdy components. Particularly, there is provided a crank shaft which drives a toothed rack member to an oscillating motion. Gear wheels connected to the journals mesh with the toothed rack member. Accordingly the expenditure in manufactur-ing the device is low and the device has a high resistance to wear. The driving unit of the device may be attached to the supporting body in different angular positions by means of a coupling device.

Abstract: A liquid agent for treating polluted water, for example in swimming pools, water courses and lakes and also effluent water, is prepared in the following four steps a- d inclusive: a) finely divided salt stone or salt-containing mineral ("Haselgebirge") or a mixture of this with a residue from salt-leeching the same ("Werklaist") is introduced, while stirring, into an aqueous solution or suspension of an inorganic base, b) the mixture is stirred for from 2 to 5 hours, c) the pH of the solution is adjusted to between 7.5 and 10.5 by adding acid or  base (lye), and d) the solution is separated from undissolved constituents, for example by decanting. In this way it is possible, in a simple manner and using naturally occurring raw materials or by products from their treatment in preparation for recovering salts, to prepare an agent which, when added to the polluted water in very small concentrations, brings about a substantial improvement in the appearance, odour, etc. of the water.
