Abstract: ABSTRACT OF THE DISCLOSURE           Packing containers in cushion-form, that is to say packing containers which comprise a liquid-tight tube which is sealed together at both ends in transverse sealing fins, cannot be used for pressurized contents, since the flexible plastic material of which the containers are made cannot be joined with sufficient strength in the sealing fins.  In accordance with the invention the pack-ing containers, and in particular their sealing fins, are strengthened by means of an external strengthening band which joins the sealing fins situated at both ends of the container.  At the same time the fins are held folded down against the  outside of the container so that the internal pressure in the container no longer acts upon the material layers sealed together in the sealing fin in a direction away from each other, but is transmitted in-stead to the seal between the respective fin and the str-engthening band which seal can readily be given the required strength.

Abstract: "Method of rolling a length of metal bar or wire and apparatus for carrying out the method"     ABSTRACT OF THE DISCLOSURE            At the end of a hot-rolling train, a metal length (bar or wire) is passed through a final roll stand and then through a cooling device.  To keep the length under tension in the cooling device, it is pulled frictionally by an opposed pair of bridle rolls which are driven, while the length is passing, with a power input which would, in the absence of the length, be sufficient to cause a peripheral speed of the bridle rolls slightly higher than the rolling speed of the length.  To prevent the leading end of the metal length being twisted or otherwise damaged on entry into the bridle rolls, the bridle rolls are driven at a slightly higher peripheral speed immediately prior to the entry of the metal length.

Abstract: ABSTRACT      "IMPROVED PLASTIC POUCH, AND STORING  AND DISPENSING METHOD USING SAME"           A pouch for containing wine or other oxygen-sensitive liquid is formed from superposed layers of plastic film having welds to define a rectangular pouch with a straight-sided or shallowly tapering passage communicating a main container portion of the pouch with the exterior of the pouch.   When the pouch is full, this passage is sealed off by a further weld which is removed by the consumer to allow the consumer to insert a separate valve into the pouch for dispensing of the liquid.          The pouch wall has an oxygen-barrier layer consisting mainly of a copolymer of vinylidene chloride-vinyl chloride as well as an outer abuse-resistant layer of ethylene-vinyl acetate and an inner sealing layer of either ethylene-vinyl acetate or polyethylene, depending on the intended contents of the pouch.

Abstract: ABSTRACT OF THE DISCLOSURE           A temperature pattern measuring method and apparatus by which portions of light from parts of an area of an object the distribution pattern of the temperature of which is to be measured, which parts are in a predetermined pattern, are passed through first and second optical filters which pass different wavelengths of light, respectively.  The level of energy passed by the re-spective filters for the respective portions of light are deter-mined by scanning the light from the filters with a pickup device or devices and using the thus determined energy levels, an arith-metic unit carries out a two-color temperature determining opera-tion for the respective parts of the area for determining the temperature on each part of the area of the object.  The temper-ature pattern of the area of the object can thereby be determined from the temperatures of the parts of the area. Also, a supervision unit for the weld zone at an electrically seamed pipe, may employ the temperature pattern measuring unit of the present invention, the supervision unit producing a composite display of the form of the weld zone and the temperature pattern thereof.

Abstract: ABSTRACT OF THE DISCLOSURE           A highly simplified speech synthesizer that is capable of producing quality speech. The present speech synthesizer is adapted to be driven by an 8-bit digital input command word. Six of the bits are used for phoneme selection and the remaining two bits for inflection control. In a first embodiment, the system if adapted to generate twelve parameter control signals for each phoneme, with one of the parameters being utilized to control both high and low frequency fricative injection into the vocal tract. This embodiment also provides asynchronous excitation of the vocal tract by including a second fricative excitation control circuit that is adapted to inject white noise in parallel into the second and third resonant filters under the control of the vocal amplitude control signal.  In a second embodiment, one of the twelve signal parameters is utilized as two separate control signals thus effectively providing thirteen control signal parameters. The vocal tract in the second embodiment is also driven asynchronously with the glottal waveform being injected in parallel into both the first and second resonant filters. The second embodiment is also adapted to be operated off a portable power supply.

Abstract: FLUX DAM FOR SUBMERGED ARC WELDING               ABSTRACT OF THE DISCLOSURE A dam, or barrier, structure is moved along the edge, or corner, of a workpiece to control the flow limits of molten material of arc welding.  The dam structure provides a dimentionally stable groove at the edge of the workpiece surface into which is received granulated flux and positions the body of the flux along the edge, or cor-ner, of the workpiece surface to function as a mold for the molten material, and, thereby, prevent the falling of the flowing material from the surface.  The dam structure has the specific form of a continuous tread of segments which advances around parallel rollers to reform the re-taining groove structure opposite the arc operation on the surface of the workpiece.

Abstract: ABSTRACT OF THE DISCLOSURE        The present invention relates to an aircraft radio telephone receiving apparatus for selecting the best signal from a group of signals transmitted from space to ground stations based upon signal strength and detected Doppler frequency errors of the received signals from the spaced ground stations.  The apparatus includes controls for tuning of the receiving means to the frequencies transmitted from the ground stations, signal strength measuring circuitry for determining the signal strength of each of the received ground station signals, measuring circuitry for the polarity and magnitude of the Doppler frequency error of each of the ground station's signal and comparing circuitry for the measurement of the ground station signals provided by the Dobbler frequency error and the signal strength defined above.  This apparatus takes into account the strength of the signal presently received as well as a measurement which allows the assessment of whether the signal is likely to improve or deteriorate in the immediate future due to the aircraft's path of travel.  The apparatus and method of the present invention provide a simple solution without the need for communication with the navigational equipment of the aircraft or other vehicle.
