Abstract: ABSTRACT OF THE DISCLOSURE          When levels of chrominance signals reproduced from a helical scan video tape recorder are controlled, two types of control signals are generated based on a level of color burst signal of the reproduced chrominance signals.  One of the two control signals is responsive to relatively rapid level changes, and the other thereof is responsive to stationary errors based on head-tape contacting pressure changes during one revolution of a rotary video head.

Abstract: ABSTRACT OF THE DISCLOSURE      A weathertight door assembly having a first sealing means on an outer frame for sealing the gaps between the outer frame and the periphery of a pair of doors when the latter is closed, and a pair of coacting second and third sealing means on one of the doors for sealing the gap between inner vertical frame members of the doors when the latter are closed.  A pro-jection extends on and along one of the inner vertical frame members for covering the gap between the doors when the latter are closed.  The second sealing means is supported on the projection and coextends with the length therewith.  The third sealing means is supported on the said one inner vertical frame member and coextends with the length thereof.  As the doors are closed, the third sealing means is sandwiched partly between the second sealing means and the other inner vertical frame member and partly between the latter and the first sealing means. \

Abstract: ROLLING CUTTER DRILL BIT     ABSTRACT OF THE INVENTION           This invention discloses a rolling cone drilling bit having a plurality of cutters which have inserted therein hard metal cutting elements preferably formed of tungsten carbide alloy; and in which bit the rolling cone cutters are located in such a manner that their rotational axes are greatly offset from the rotational axis of the drill bit.  In addition, a fluid jetting system is provided in the invention that directs a pres-surized fluid spray across the main cutting inserts and against the formation face so that when the drill bit is used in its most advantageous areas, such as the soft, medium-soft and plas-tic formations, the jetting system prevents "balling up" of the cutters and greatly increases the drilling efficiency of the bit.

Abstract: ABSTRACT OF THE DISCLOSURE       A small orifice in a flush valve piston is provided with a filter means to prevent sedimentary deposits from clogging the orifice.  The filter is formed by providing a generally three-sided channel around the piston.  The channel is located such that the orifice opens into the base of the channel.  A resilient sealing ring is seated on the channel to close the open side of the channel.  A plurality of grooves extend from the interior of the channel, under the sealing ring and to the exterior of the piston.  These grooves are sized to prevent en-try of sedimentary deposits into the channel while permitting entry of water in the channel.  The grooves are individually small compared to the orifice opening but they are sufficient in number to provide an adequate supply of water to the orifice.

Abstract: The invention relates to a method for the monitoring and control of operating parameters of a machine for the continuous casting of strips between rolls, including the torque exerted on at least one of the rolls to cause the strip to advance and/or the stress exerted by the strip on at least one of the journals and/or the temperature of the strip as it leaves the rolls and permanently measuring the deviation between the instantaneous value of one of these parameters and the mean value of this parameter over a period of time immediately beforehand. If this deviation exceeds a reference deviation, the casting speed of the machine is reduced until the deviation again becomes less than the reference deviation. The speed of the casting machine is then increased for as long as this deviation remains lower than the reference deviation.

Abstract: Auxiliary Engine Stoppage Apparatus Abstract Apparatus for stopping an engine from a remote location relative to an operator's work station.  An engagement apparatus which is displaceable between first and second positions is engaged with an engine stoppage member which, when rotatably displaced by the engagement apparatus between two positions corresponding to the first and second positions of the engagement apparatus, can permit engine operation or induce engine shutdown.  An actuating link interconnected with engagement apparatus is displaceable, when subjected to a momentarily applied external force, between engine operating and engine shutdown positions.  A spring biases engagement apparatus towards the first and second positions when the actuating link occupies the engine operation and shutdown positions, respectively.  Externally applied forces on actuating link are not transmitted directly to the engine stoppage member since the spring completes the movement of engagement apparatus to first and second positions in response to movement of actuating link.  Consequently, no damage occurs to stoppage member but engine stoppage is assured.

Abstract: IMPROVED PRESSURE DETENT MECHANISM     Abstract of the Disclosure A hydraulic system includes a selective control valve and a cam member movable to selected positions for controlling a hydrau-lic cylinder powered by a pump.  A follower is urged to a locking relationship with the cam by a hydromechanical mechanism to releasably hold the control valve in the selected positions. The hydromechanical mechanism includes a bore exposed to sump pres-sure and to pressure upstream and downstream from a metering valve in a passage interconnecting the pump and the control valve.  A hollow apertured sleeve is movably mounted in the bore. An apertured piston is slidably received by the sleeve.  A rod, engageable with the follower, extends through the piston and sleeve apertures.  A fist spring interconnects the rod and the piston and a second spring interconnects the piston and the sleeve.  The sleeve moves to a preload position in response to a no-flow differential pressure between the sump and the passage to urge the follower Via the rod towards its locking position.  The piston moves in response to fluid flow through the passage to bias the follower toward its locking position.  The piston and the rod move to automatically allow the follower to release from the cam when the function of the hydraulic cylinder is completed. Also, the sleeve and rod move to automatically allow the follower to release from the cam when system pressure in the passage is lost.
