Abstract: An apparatus is disclosed with which a graphics designer can select an exact color to be shown on a video display device. The apparatus includes a control element movable in a region having at least two geometrical dimensions, each position in the region corresponding to a different color. If the region is only two-dimensional, the color element position defines two of the three independent variables needed to define the desired color, and the third is controlled independently.

Abstract: A method and apparatus are disclosed for scrambling and descrambling an audio signal. An interference signal is generated and is intermittently, preferably pseudo-randomly, added to the program audio as a function of control information generated either by means of hardware alone or by means of software. The scrambled audio and the interference signal are preferably transmitted on two carriers, e.g., two standard subcarriers used in TV broadcasting, together with the control information. A decoder descrambles the audio by substracting the interference signal from the scrambled audio at the proper times as indicated by the control information. Preferably, the interference signal, comprising a series of noise bursts, is transmitted on the same carrier as the control information, time-multiplexed with the latter. Alternatively, the program audio itself, subjected to a time delay, is used as the interference signal, in which case the second carrier bears only the control information.

Abstract: A process for warm-working a forged austenitic stainless steel workpiece to improve its mechanical and physical properties is disclosed. The workpiece is subjected to a force great enough to cause deformation while the surface temperature of the workpiece is elevated in the range of above about 200.degree. F. (95.degree. C.) to below the lower critical temperature. The purpose of using elevated temperatures is to reduce the force required to deform the workpiece. Stabilized austenitic stainless steel can be warm-worked and still maintain its corrosion-resistant properties. The advantages of warm-working over cold-working to achieve properties are reduction of noise and improved metallurgical control.

Abstract: A pipe mold for centrifugally casting pipe is disclosed. The pipe mold according to the present invention is made by depositing weld material on a rigid shell. The rigid shell is obtained by forming a flat plate into a cylinder and welding the resultant seam. Additional rigid shells can be circumferentially welded together to obtain a desired length. The welded seams are areas of weakness called metallurgical notches. To eliminate the metallurgical notches, weld material is deposited on the shell. In one embodiment, weld material is deposited on the outside of the shell. The shell then is machined away. The resultant pipe mold has a total wall thickness comprising weld material and is free of metallurgical notches. In addition, the need for furnace heat-treatment to achieve properties in the weld material can be eliminated.

Abstract: A method for induction hardening through hardened chromium-molybdenum hot work die steel comprising the steps of induction heating to a uniform temperature above the upper critical temperature, cooling, and double tempering at temperatures below the lower critical temperature to produce a workpiece having a tough core and a hard wear resistant surface. An apparatus is provided for induction hardening long workpieces with minimum distortion by providing an inductor coil which always remains centered around the workpiece during induction coil traverse. Mandrel bars for tube piercing mills can be induction hardened using this process and apparatus.

Abstract: A method and apparatus are disclosed for severing or otherwise cutting cigarette filters, tobacco rods and the like. According to the invention, a slitter knife is maintained in whetting engagement with a whetting mechanism, so that the slitter knife never becomes dull. This is preferably achieved by mounting the slitter knife on a pivotable carriage and providing an automatic control system which pivots the slitter knife to maintain it in the desired engagement with the whetter. A feedback system can be included, to monitor the sharpness of the slitter knife and to indicate when adjustment of the slitter knife position is required.

Abstract: The present invention is a process for removing covering material from a bale of, for example, Oriental tabacco leaves at production line speeds which causes only minimal damage to the underlying bale and only minimal contamination of the underlying bale with particles, fragments and/or fibers of the covering material.

Abstract: The present invention is a reflective snowplowable road marker (1) of unitary construction for disposition in a road surface without adhesive having an outwardly dished top section (4) with a relieved channel (8) extending across the top surface (5) of the top section (4) with the channel (8) being adapted to receive therein a reflector (6), and a bottom section (10) disposed from the bottom surface (22) of the top section (4) which has a cylindrical shape and a plurality of spaced apart gripping means (14) disposed on the outside surface of the bottom section (10).

Abstract: A method and apparatus for continuously measuring the compressive strain and determining the compressive pressure on rolls of flexible material as they are being wound and for measuring the accumulated length of material wound on the roll. An accurate measurement is recorded of the length and caliper of each layer of the roll. From these measurements, the compressive strain and compressive pressure are determined and this information is used to control the winding process. The length measurements are also employed to correct the accumulated length measurement after the winding has been interrupted for removal of defective layers of material.

Abstract: A high-speed dynamic porosimeter including a device for removing accumulated debris is disclosed. The porosimeter has an apertured surface, preferably curved, across which a web whose porosity is to be measured is drawn while suction is applied to the apertures. A pressure transducer monitors the pressure in a sensor line or chamber, which pressure varies as a function of the porosity of the web. A scraper blade scrapes debris from the apertured surface from time to time. Preferably, vacuum suction is also applied to a slot at the upstream side of the apertured surface to ensure a good seal between the web and the surface.

Abstract: A method is disclosed according to which a cylindrical object, such as a rod of smoke filter material, is pressed against a heated former element to form a permanent impression in one portion of the object as the former element and the object are simultaneously moved along a predetermined path. The object is then disengaged from the first former element, and pressed against a second heated former element to form a permanent impression in another portion thereof as the second former element and the object are moved along a second predetermined path, which may be an extension of the first, or not. Apparatus is disclosed, in one preferred embodiment of which the first and second former elements are disposed on the periphery of respective drums in such a manner that as the drums rotate in opposite directions, the object is transferred from the first to the second former element as the two former elements pass each other.
