Abstract: MAGNETIC RECORD MEMBER FOR USE WITH ROTATING        HEAD MAGNETIC RECORDING APPARATUS                    Abstract An elongated magnetic tape has a pair of longitudinally extending servo track areas, one of which is closer to the longitudinal center of the tape than the other.  The lateral space intermediate the servo areas receives data signals, while the space between said one servo area and one edge contains identification and address signals.  The tape is par-ticularly adapted for use with rotating head recorders having two gaps on the rotor, with an intergap distance slightly greater than the lateral extent of the servo areas.  A recording or write gap precedes an immediately trailing reading or recovery gap.  When the rotor gaps pass the one edge in the one servo area, the write gap senses the servo track; while the read gap senses the identification signals.  The arrangement is such that prior to the time the write gap reaches the data recording area, the read gap has sensed the identifi-cation signals.  In a similar manner, when the gaps are leaving the data signal area, the write gap is sensing the other servo area; while the read gap is still sensing data.  The longitudinal extent of the servo areas indicates, respectively, beginning of tape (BOT) and end of tape (EOT).  A leader portion includes a magnetic coating for facilitating calibrating magne-tic recording apparatus to each particular article.

Abstract: ABSTRACT OF THE DISCLOSURE           A fire hydrant having a unitized bonnet configura-tion or assembly which includes a bonnet member, operating mechanism, external driving attachment and lubricant reser-voir and which may be installed and removed from the hydrant barrel without the loss of lubricant from the lubricant reservoir therein or without the major disassembly of parts.          Additionally, the unitized bonnet assembly is provided with a stop nut member which may be adjustably secured to the end of the valve stem to compensate for small variations in barrel lengths and/or valve stem lengths.  The stop nut member is carried within the lubricant reservoir of the bonnet member and is at all times sealed from water in the hydrant and, thus, it may be made of a non-corrosive resis-tant material such as ductile iron or steel which is less expensive than corrosive resistant material such as brass, bronze or stainless steel.  The adjustable connection between the stop nut member and the end of the valve stem is like-wise protected from exposure to the water system by being fully contained in the lubricant reservoir system and thus the joint between the two is not subject to corrosion.  The stop nut member which reciprocates upon rotation of the operating nut assumes the torsional loads rather than the valve stem.

Abstract: Abstract of the Disclosure An  improved video display system is provided in which two color images are combinable in a dynamic and self-determining fashion to pro-vide improved contrast, comprehension and display versatility. Two separate video signals that are to be used in generating a single dis-play are converted into sequences of digitally encoded picture ele-ments (pixels).  Control signals are generated that are dependent upon the data content of the elements in at least one of the sequences, and these signals are used to govern the mode of combination of the two video signals for individual pixel sets.  For example a first video sig-nal of digital character and having varying pixel intensity may be trans-formed into color values for a first pseudocolor display.  A second video signal, derived from an analog source, is digitized and is also transformed into pseudocolor, concurrent with the dynamic generation in real time of the data dependent control signals.  Such control signals may be incorporated in either or both of the digitized data sequences, and the second video signal may be digitized with or without adjustment of intensity ranges within variable limits.  The two transformed digital signal sequences are then arithmetically or logically combined in ac-cordance with the functions defined by the data dependent control signals. For example, the signals may be added, ANDed, ORed, averaged, subtracted, or one or the other can be blocked, and these functions can be varied, dependent upon the data, in incremental fashion within the display. Consequently, the contrast between the two color images can be selectively enhanced, the data contained in the images can be much more clearly de-picted in graphical form, and special effects can be obtained in versa-tile and discretionary fashion.

Abstract: ABSTRACT The invention is directed to a power driven tool for recipro-cating a cutting element such as a saw-blade or the like and in-cludes a motor housing and a drive motor mounted in the motor housing. A gear case is connected to the motor housing and the shaft arrangement is mounted in the gear case.  The shaft arrange-ment includes a shaft slideably mounted in the gear case for re-ciprocating movement.  The shaft is adapted to receive the cutting element thereon.  A U-shaped channel yoke is mounted to the drive shaft in such a manner that the walls of the drive shaft laterally support the U-shaped channel yoke at the base of the yoke.  An eccentric drive connects the U-shaped channel yoke with the drive motor for reciprocating the shaft arrangement.      A method of assemblying the shaft arrangement includes the step of cutting two slots in the base of the channel yoke to define three bridges one adjacent the other bridging the gap between the leg walls of the yoke.  The channel yoke is then inserted into the notch-like cut-out of the shaft so as to cause the channel yoke to engage the annular wall of the shaft in the slots at the bottom region of the cut-out.  In this way, the center bridge of the channel is disposed between the inner walls of the shaft. The channel yoke is then brazed to the shaft at the interface be-tween the channel yoke and the shaft.
