Abstract: ABSTRACT OF THE DISCLOSURE           This specification discloses a tube connector system adapted to convenient and removable assembling of square, round or other shaped hollow tubes.  It finds use in the construction of temporary and permanent store displays, furniture, shelves, and the like.  In one embodiment the connector comprises a joining member having a plurality of insertion members each of which in closely but  slidably fitted to the aperture in the end of a hollow tube.  Each insertion member has a plurality of recesses on the side thereof.  Each recess is provided with a resilient spring member, said spring member having a portion resting on the bottom surface of said recess, and a portion protruding above the top of said recess, permitting forceable entry of the insertion member and retaining it removably in place in the tube.  No rotation of the parts is necessary for secure assembly, and no external parts such as screws, bolts, and the like are needed.  A joining member involving a plurality of these insertion members can be used for assembling various types of structures, including two or three dimensional assemblies.  In a preferred embodiment this spring member is formed from substantially flat spring metal such as spring steel, and is curved to provide a force fit between the insertion member and the inside wall of the tube.

Abstract: ABSTRACT OF THE DISCLOSURE           Improved transmission line voltage breakdown strength is achieved by applying magnetic fields in trans-mission lines.  In colinear transmission lines, particularly coaxial cables, one means of magnetic field introduction is accomplished by applying an axial magnetic field about the transmission line, which together with the self-induced power current magnetic field creates a net helical magnetic field whose pitch is dependent upon the relative magnitudes of the azimuthal component of the self-induced magnetic field and the axial component of the applied magnetic field. The applied magnetic field may be achieved by a permanent field or by directing either an alternating current or direct current through a helical winding defining a solenoid coaxial with the transmission cable. Alternatively, the applied field may be achieved by surrounding the grounded sheath with oriented ferrite or other magnetic material in a suitable support medium such as a pliable plastic bond form to produce a multipole magnetic field.

Abstract: ABSTRACT OF THE DISCLOSURE      A simplified voltage regulating circuit is provided for controlling the operation of a d-c to d-c converter oscillator as is commonly used in an electronic flash. The voltage regulating circuit controls the operation of the d-c to d-c converter so that the output voltage from the oscillator is maintained within a prescribed range. The voltage regulating control circuitry includes an ordinary transistor controlled by way of an output voltage sensing zener diode which operates to turn on the transistor and thereby terminate operation of the oscillator when the output voltage therefrom reaches its maximum value within the prescribed range. A capacitor is also charged by way of the transistor when it turns on and the residual charge of the capacitor thereafter operates regardless of the non-conductive state thereafter assumed by the zener diode and transistor to maintain the oscillator off until the output voltage from the oscillator decays to its minimum value within the prescribed range.

Abstract: ABSTRACT OF THE DISCLOSURE         A control device for metering fluid flow from a remote location is shown in conjunction with an insecticide spraying apparatus.  The spraying apparatus includes a compressed air source feeding pressurized air to a nozzle for mixing with a liquid and discharge to atmosphere.  A metering pump feeds the liquid to the nozzle in response to a digitized input signal received from a remote control device.  A digitized feedback signal including a number of pulses per unit time from the metering pump to the remote control device indicates the rate of flow of the liquid through the metering pump.  The remote control device compares the digitized feedback signal with a control voltage to generate the digitized input signal which is a pulse width modulated signal, which digitized input signal maintains the flow rate of the liquid.  A pressure switch connected to the nozzle insures a predetermined pressure therein before the metering pump will begin feeding liquid to the nozzle.

The acids can be readily produced in good yields and their solubility in water is very good for most purposes.  They are good complexing agents with respect to divalent and poly-valent metal ions and can be applied with advantage wherever good complexing efficiency is required.  Their hydrolysis re-sistance at high temperatures is particularly good so that they are applicable in all the cases in which temperatures above 100° are applied.  They can be used in any medium in which the water softeners have an adverse effect or in which the influence of polyvalent metal ions is to be eliminated.  This applied in particular to the treatment of hard water, baths for treating textiles, papermaking and tanning.

Abstract: ABSTRACT OF THE DISCLOSURE            An omega-hydroxy alkenoic acid containing 8 or 12 carbon atoms is obtained by the selective reduction of the carbonyl group of an omega-formyl alkenoic acid, for example by the use of sodium borohydride, and wherein the starting acid is produced by the ozonization and transposition of a polyunsaturated hydro-carbon cycloolefin.  The unsaturated omega-hydroxy acids have important applications, e.g. use in making polymers or copolymers whose reactivity, due to the presence of double bonds, enables them to be used for the manufacture of products which in turn possess desirable properties.  Examples of such products are textile products possessing a high degree of dye-ability and additives for anti-static agents or for resins, all of which is easily under-standable by persons skilled in the art.

Abstract: A process for improving the flavour and/or the mousseux of sparkling wines and sparkling wines produced according to said process.     ABSTRACT OF THE DISCLOSURE           A process for improving the flavour and/or the mousseux of sparkling wines is described. Sparkling wines are wines which contain a permanent visible excess of car-bon dioxide, like champagne, Sekt, crackling wines and vino spumante. Of said sparkling wines the most preferred organoleptic properties, i.e. flavour, fragrance and taste, which is also influenced by the special properties of the excess carbon dioxide of said sparkling wines, and also the most desirable formation of small carbon dioxide bubbles when the bottle is opened, i.e. the most preferred mousseux, have such sparkling wines which are prepared according to the time consuming and very expensive champagne method. In the present process the flavour and/or the mousseux of any kind of sparkling wines, i.e. those prepared according to the champagne methode, and also those which are prepared according to far cheaper methods, is highly improved by adding at least one material selected from the following group of materials, which comprises: amino acids, amino acid derivatives, thiamine (vitamin B1) and thiamine-pyro-phosphoric acid salt (thiamine diphosphate salt ). A spe-cial preferred product which is added is a hydrolysate of a protein containing material, preferably an autolysate of yeasts. Said material can be added in any step of the process for making the sparkling wines, prior to the final corking of the filled bottles.
