Inventor: SENDELWECK G K
IPC: H04N9/455
Filed: 1977-02-18
Abstract: BURST GATE PULSE GENERATOR of the Invention A burst gate pulse generating circuit includes a switching transistor having an input coupled to a source of pulses representative of a horizontal sync component of a video signal which includes a burst interval, and having an output coupled to an LC resonant circuit with a predetermined LC time constant.  The resonant circuit is excited into ringing when the transistor conducts in response to an input pulse, and a resulting ringing waveform is used in conjunction with the inverse conduction characteristic of the transistor to turn off the transistor prior to the completion of one full cycle of ringing.  An output  voltage pulse is provided which is coincident with the burst interval and which corresponds to the first full half cycle of one polarity of the ringing waveform.

Abstract: The invention disclosed herein relates to a tightening system for tightening an assembly including a threaded fastener including a wrench for applying torque and imparting rotation to the fastener. Associated with the wrench is a control system including measuring means for developing a first signal representative of the angular displacement of the fastener. A second signal representative of a constant incremental time is introduced along with the first signal to gradient calculating means which develops a signal representative of the slope or gradient of an angular speed vs. angular displacement curve which could be plotted for the particular assembly being tightened. When the gradient signal falls to a predetermined percentage of a maximum previously stored gradient signal, at the yield point of the assembly or some similarly significant point characterized by a significant change in slope on the angular speed vs. angular displacement curve, a control signal is generated stopping the tightening of the assembly.

Abstract: The elastic bandage knitted with a coarse mesh contains a group of composite parallel warp yarns (10) and a group of non-elastic filling yarns (12). Each warp yarn has a first and a second false-twist filament yarn. The first false-twist filament yarn is shaped to form fringes. The second false-twist filament yarn has the opposite direction of rotation and is inserted into the loops of the first false-twist filament yarn. The filling yarns are inserted into the warp yarns in a pattern recurring over the width of the bandage. They are arranged in pairs in each pattern. The filling yarns of the individual pairs run in a serpentine manner. The surface of the bandage is such that the various layers of the wound-up bandage adhere to one another. <IMAGE>

Abstract: Subsynchronous oscillations and direct current displacement in an electrical power system are damped by the half period of the current or voltage connection waves being measured, then compared with a required half period. Any waves with a longer half period than that desired are eliminated. The device used incorporates a reactance (28) which is connected into a power line (30) by selective double direction connections (34,36) parallel to it, so that it is possible to short circuit it. An alternative arrangement is for the double direction connections to connect the power line to earth when the half period times exceed the stipulated level. (Provisional Basic advised Week D11)

Abstract: A so-called insulation screen has, for its fastening to a power transmission pole or the like, two guide channels 6 running in the transverse direction of the screen for spring-loaded fastening elements 8, 9 provided with gripping elements 9a, 9b. The mouth portions of the guide channels are downwardly directed at a slant or downwardly bent and the gripping elements are normally engaged with these mouth parts. Thanks to the shape of the guide channels, the fastening element cannot accidentally move up against the current-carrying lines above. It is convenient to fashion the guide channels from plastic tubes 6 secured to the bottom of the screen. In order to hold the screen level with the ground surface, the screen also has a slanting sleeve 4 for detachable connection with a rod or a tube. <IMAGE>

Date Jun. 9, 1983.A self-retaining post of a plastic material, such as PVC, for use as a roadside marking post, a traffic sign post, a lamp post, or for other comparable uses in road traffic environments, has a channel-shaped bending zone with substantially arcuate cross-section and with the convex side facing the on-coming traffic. The cross-sectional area of the bending zone increases progressively towards the lower end, whereby the flaring-out zone formed upon bending of the post will be larger below than above the line of bending. The greater inherent resiliency of the material below than above the line of bending will cause the post to bend back into an upright position after having been hit by a vehicle. Certain embodiments of the posts are manufactured by diagonally splitting lengths of extrusion-molded plastic tubing, forming two identically shaped posts from each tube length.

Abstract: A drill screw having protective burrs on the cutting edges. These burrs preserve the sharpness of the cutting edges against heavy plating buildup which can have detrimental effects on performance. Further, whereas conventional burrs on the drag surfaces can be reinforced and serve to thicken the dimension of the point across the chisel, the burrs of the present invention are formed on the cutting edge in such a way that they are spaced from the chisel. Drilling can, therefore, begin immediately and continued penetration of the workpiece pushes the burrs into the material being drilled causing them to break off.
