Title: Television receiver with synchronous  detector and common reference  oscillator
Inventor: HONGU MASAYUKI
IPC: H04N5/50
Filed: 1979-05-15
Granted: 1982-09-14
Abstract: ABSTRACT         An automatic fine tuning loop in a television receiver is controlled by phase comparison between a video intermediate frequency signal and a reference oscillator signal.  The reference oscillator signal is used in synchronous detection of the video intermediate frequency signal.  The frequency of the reference oscillator is controlled by a phase locked loop, of which it is a part, and which includes a low-pass filter having selectable high and low cut-off frequencies.  A lock-out detector selects the high cut-off frequency for rapid correction when lock-out is detected and selects the low cut-off frequency for frequency stability when lock-in is detected.  An AFT disable switch dis-ables the automatic fine tuning loop during manual tuning.  In one embodiment, a disable switch ganged with the AFT disable switch selects the high cut-off frequency in the low-pass filter to pre-vent hunting.

Abstract: ROTARY CUTTING MECHANISM                 Inventor:  CARL A. STOFFELS                          Abstract A rotary cutting mechanism for transversely slicing an elongated rotatably driven roll of material such as plastic film into a number of narrower rolls in-cludes a pair of spaced-apart knife cutting blades mounted for free rotation about an axis parallel to the longitudinal axis of the roll.  A rotary saw blade is mounted intermediate and in axial alignment with the cut-ting blades, and is independently driven to remove material between the cutting blade edges as the blades are moved together to slice the roll.  The finished nar-rower cut rolls therefore exhibit smoothly finished side edges and are readily separable from each other, there being no frictional heat developed by the cutting blade edges which are free to turn with the material on the roll as they slice through it.

Abstract: WELL TEST SYSTEMS AND METHODS          Abstract of the Invention A well packer and depending foot valve are landed in a well.  A landing nipple depends from the foot valve.  A tubing string sealingly engages the packer and includes a circulating valve.  A transducer-valve fitting may be run with the packer foot valve assembly or it may be run at a later time and landed in the landing nipple.  The foot valve is operated by an actuator which is positioned above the packer and is ex-posed to the casing tubing annulus as well as tubing pressure.          The circulating valve is also exposed to casing-tubing and tubing pressure.  The foot valve is controlled by the differ-ential in pressures as is the circulating valve.  A transducer may be landed in the transducer fitting and by selectively opening and closing the foot valve data may be taken from the well during both flow and non-flow conditions.  After testing is completed the transducer and transducer fitting may be removed and a plug inserted in their place permitting flow thereafter through the foot valve which acts as a subsurface safety valve.

Abstract: ABSTRACT    A placement bucket for placing material such as concrete in forms by manipulation of clam shell gates in response to action of a power cylinder makes use of a hydraulic fluid system which prevents opening the gates of a full or partially full bucket of material unless there is a sufficient reserve of pressure and fluid volume to make certain of closing the gates at any time.  The system is provided with a precharged fluid supply under pressure into which additional fluid is diverted when generated in a master cylinder by lifting a piston against the weight of the bucket and its contents.  A sequence valve prevents flow of fluid to the power cylinder until an optimum amount of fluid pressure and volume is reached.          An auxiliary direction valve in a fluid return line can be manipulated to temporarily block return flow of fluid from the exhaust side of the power cylinder to a reservois, in that way to temporarily fix the partially or full open position of the gates.

Abstract: APPARATUS FOR ASSEMBLING CLOSURES AND CONTROL SYSTEM THEREFOR Abstract of the Disclosure An improved multi-station machine is disclosed for assembling ring-type closures from generally cylindrical paperboard cylinders and generally circular paperboard discs. The machine employs a rotatable dial plate, carrying eight mandrels and an improved ring clamping system, which dial plate is incrementally rotated by an automatic indexer assembly relative to the various operating stations which consist of a ring feed station, a disc feed station, an adhesive dispensing station, a curling station, a grooving station and a closure ejecting station. Means are provided for controlling the operation of the various stations so that they operate in substantial synchronism with one another and with the rotatable dial plate. The improved disc feed station automatically feeds the lowermost disc from a stack of discs to a position over a ring on the dial plate and simultaneously forms a peripheral skirt on the disc and positions it in an open end of the ring. The adhesive dispensing station employs a pair of tube pumps to dispense adhesive and lubricant on partially assembled ring-type closures. The grooving station automatically forms a peripheral groove and a corresponding radially inwardly extending rib in the cylindrical wall of an assembled ring-type closure. The closure ejecting station provides vacuum means for withdrawing a completed closure from a mandrel on the dial plate and pressurized air means for assisting in the automatic removal of the closure from the mandrel and for automatically propelling the thus removed mandrel from the machine. The ring feed station provides means for preventing the introduction of rings onto the dial plate in response to an indication of insufficient discs at the disc feed station. Control means are provided for manually indexing the dial plate as well as prevention of disc feed, and adhesive and lubricant dispensing if an appropriate ring is not present on the dial plate, as well as control means for preventing ring feed if sufficient discs are not available at the disc feed station. Various other control features are disclosed for the prevention of operator injury, material waste and machine jamming.

Abstract: ABSTRACT OF THE DISCLOSURE An electrical screening system for binary displays or binary graphic recording systems is dis-closed which suppresses false contours.  The suppression is achieved by increasing the number of gray levels that a given m x n matrix of pixels can represent. Each pixel can only represent one of two gray levels in a binary display or graphic system.  A conventional m x n halftone cell is able to reproduce m x n + 1 gray levels.  The extra gray levels above the m x n + 1 quantity are achieved for a given m x n halftone cell by dynamically changing the values of the m x n screen signals associated with a halftone cell.  The amount of the change is limited to a value between zero and D inclusive where D is the difference between two adjacent screen signal values.
