Abstract: Abstract of the Disclosure A shaper cutter includes a conical body having teeth formed around its periphery and a flexible wafer is disposed against the face of the body and is formed with peripheral teeth overlying the teeth on the body.  The face of the body is concave and conical so that, when the center portion of the wafer is clamped to the body, the wafer flexes to lie against the face with the result that the teeth on the wafer are held firmly against the teeth on the body.  The edges of the teeth of the wafer constitute the cutting edges of the cutter so that, when the cutting edges become dull, the wafer is simply removed and replaced with a new one.  In another form, the teeth on the body are helical and their end faces are inclined in stepped relation while the wafer teeth are on the free ends of flexible fingers which, when the wafer is clamped to the body, flex to lie against the end faces of the teeth on the body.

Abstract: ABSTRACT OF THE DISCLOSURE        Method and apparatus for priority masking of video enhancement areas of a video picture.  A first enhancement conversion formula is generated for enhancing a first segment of the video picture according to the first generated enhancement conversion formula.  Similarly, a second enhancement formula for enhancing a second segment of the video picture according to the second enhancement conversion formula is generated.  Priority of one conversion formula over the other in the area of overlap of the two segments is established by combining the first and second enhancement conversion formulas in a manner to produce the composite enhancement conversion formula in which one of the first and second enhancement conversion formulas has a degree of priority over the other enhancement conversion formula in the area of the video picture in which the overlapping occurs.  The video picture is thus modified according to the composite enhancement conversion formula.          When more than two segments having their individual enhancement conversion formulas, the composite enhancement conversion formula is established such that, in the area of common overlap of the three segments, one of the first, second, and third enhancement conversion formulas has a first degree of priority over the other two, and one of the other two enhancement conversion formulas has a second degree of priority over the other one thereof.  In a preferred embodiment, the enhancement modification and conversion is the colorization of a black and white or an undesirably colored video picture.

Abstract: Abstract The invention relates to a method of manufacturing a body for a container, in which a body having a weldseam along its longitudinal direction is formed by bending ma-terial in sheet form and welding the overlapping edges of the bended material together, and the wall of the body ha-ving the longitudinal weldseam is thinned.      Preferably thinning is obtained by wall-ironing. It is advantageous that the wall thickness of a wall part close to wall end of the body is larger than that of a remaining part of the body and eventually prior to thinning has been redu-ced and that prior to being reduced the body is provided with a gripping rim and/or cover.

Abstract: ABSTRACT OF THE INVENTION           A mass data acquisition system utilizes a record-er that is provided with both CMOS RAM and a removable memory cartridge.  The memory cartridge can be used to transport data from the recorder to a translator.  Further-more,  the  CMOS RAM is used to  store the data record formulated during an entire recording period.  When operat-ed in the RAM mode, all data is stored in the CMOS RAM and the data cartridge is used only for purposes of transport-ing data to the translator.  When operated in the cartridge mode, all formulated data is stored in both the CMOS RAM and  the  cartridge.   This  cartridge  mode  of  operation provides redundancy and serves as  a backup dual memory system to prevent loss of data in the event that a memory malfunction occurs in either one of the two memory media. The recorder can also communicate with a translator over phone lines in conjunction with serial I/O and a MODEM. When communicating with a translator on the phone line, data can by obtained from either a cartridge, when in the cartridge mode, or directly from CMOS RAM when in the RAM mode.

Abstract: Hybrid Generating System Abstract Prior types of generating systems for producing AC and DC output power have utilized integrated drive generators for producing the AC power and means for rec-tifying the AC power developed by the drive generator to produce the DC power.  However,  such types of systems encounter various disadvantages, including less than de-sirable reliability of the DC power, distortion in the AC power caused by rectification thereof to produce the DC power and reduced efficiency.  In order to overcome these problems,  a hybrid generating system according to the present invention comprises an AC power generating sec-tion driven by a prime mover for generating AC output power and a DC power generating section independent of the AC power generating section, also driven by the prime mover for generating the DC output power wherein each of the AC and DC power generating sections includes a perma-nent magnet generator.  The AC and DC power generating sections may be provided in a common housing to provide a compact hybrid generating system in which reliability and efficiency are increased and distortion in the AC output power caused by generation of the DC output power is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE          Mixtures of aromatic diamines, polyurethanes made therefrom, and processes for the preparation of the polyurethanes.  The mixtures of aromatic diamines of the invention comprise a first aromatic diamine having a machine gel time of 1 to 4 seconds in a 50,000 psi modulus RIM formulation reaction and the second aromatic diamine having a slower machine gel time of 1.5 to 15 times that of the first aromatic diamine.  The mixtures provide gel times of 2.5 to 10 seconds, suitable for filling large molds such as automative body panels.  The novel aromatic diamine mixtures allow use of larger proportions of diamine to provide polyurethanes which are rigid but not brittle at demold and have unexpectedly superior flexural modulus properties.  The polyurethanes formed with the chain extender mixtures of the invention have flexural modulus superior to polyurethanes formed from either of the diamines individually.
