Abstract: ABSTRACT OF THE DISCLOSURE     A system for reducing noise in a television signal utilizing integration and including a storage device for storing a television signal, and a summing device for adding a fractional amplitude portion of the signal stored in the storage device to a fractional amplitude portion of an incoming video signal, and operative automatically to change the fractional amplitude portion of the stored signal fed to the summing device as a function of the difference between stored and present signals, thereby to change the integration time constant of the system to accommodate for motion between the incoming signal and the stored frames, is improved by eliminating from the noise-reduced output signal troublesome transients caused by not changing at the appropriate time the fractional amplitude portion of the stored signals fed back to the summing device.  This problem is overcome by generating in response to the difference between the incoming and stored video signals a gating waveform during the existence of which an increased portion of incoming video is coupled to the output of the system, delaying the incoming and stored video signals by an arbitrary amount sufficient to ensure that the onset of the gating waveform occurs sufficiently in advance of the de-layed incoming and stored video signals as to be anticipatory of the delayed arriving and stored signals, and delaying the turn off or termination of the gating waveform thereby to de-lay the return to a condition of coupling a lower value of the fractional amplitude portion of the incoming video signal than occurred during the gating waveform.

Abstract: A METHOD FOR MAKING FLAT    CELLULAR VINYL SHEET                    Abstract of the Invention Flat cellular vinyl chloride and vinylidene chloride polymer sheets are made by coextruding a cellular forming chloride or vinylidene chloride polymer material with a noncellular, incompatible polyolefin capstock. The noncellular, incompatible capstock restricts the expansion of the cellular material in the lateral direction, thus maintaining the sheet in a flat condition.  Since the capstock is incompatible, it can be easily stripped off the cellular sheet after cooling or after the sheet is converted into the final product.

Abstract: TITLE OF THE INVENTION                   HYDROMECHANICAL TRANSMISSION                     ABSTRACT OF THE DISCLOSURE A heavy duty hydromechanical transmission adapted for agricultural and industrial type tractors and for heavy duty construction type vehicles as well as line haul tractors is disclosed.  The transmission utilizes an input shaft which is driven by a power source and drives dual planetary gear sets.  These planetary gear assemblies are each geared to two separate variable displacement hydrostatic pump and/or motor units which are arranged in a closed hydrostatic fluid flow circuit.  Each planetary gear set also drives a counter-shaft which is utilized as part of a multispeed transmission.   The hydrostatic units are used as variable displacement pumps or motors to obtain smooth starting and to eliminate the need for a conventional master clutch normally used for starting a vehicle or for shifting gears. These units are also used to provide the high-starting torque through hydraulic torque regeneration.  Hydrostatic transfer of power between fixed gear ratios (bases) creates an uninterrupted power flow over the entire speed range of the vehicle.  Either or both of the hydrostatic units is available to be driven as a pump to provide high hydraulic line pressure for auxiliary hydraulic power take off devices such as concrete mixer drums, secondary vehicle drive axles, vehicle hoist mechanisms, etc.  These units may be utilized as pumps to provide high levels of modulated dynamic braking horsepower. They may also be used to extend the limits of vehicle operation by providing a hydraulic over-drive which also allows an associated engine to operate at lower and quieter speeds and in a more efficient fuel economy range.

Abstract: ABSTRACT OF THE DISCLOSURE       An improved specific binding assay method and reagent for determining a ligand in a liquid medium employing, as an enzyme-cleavable substrate label, a residue having the formula:                       G-D-R   wherein G is a glycone, D is a dye indicator moiety, and R is a linking group through which the label residue is covalently bound to a binding component of a conventional binding assay system, such as the ligand, an analog thereof, or a specific binding partner thereof.  The monitored characteristic of the label is the release of a detectable product, usually a fluorogen or chromogen, upon enzymatic cleavage of the glyco-sidic linkage between the glycone and the dye indicator moiety.  The assay method may follow a homogeneous or hetero-geneous format.  The preferred glycone is a .beta.-galactosyl group and the preferred dye indicator moiety is an umbelliferone residue.  The improved assay is particularly suited to the determination of haptens such as drugs, particularly the aminoglycoside antibiotics.

Abstract: A METHOD FOR CALCITE COATING ON THE INNER SURFACE OF PIPES              ABSTRACT OF THE DISCLOSURE         Disclosed is a method for obtaining a tenacious in situ coating deposition of calcite on the inner surface of water pipes.  The calcite coating method according to the present invention has an advantage that it is able to maintain a completely corrosion-free system during the coating, thus assisting the formation of a protective coating of good bonding properties.  The method consists in the incorporation of a reagent selected from the group consisting of alkali metal sulfite and hydrazine, in an amount which is at least the stochiometrically required to deoxygenate the aqueous solution utilized for said coating, which is supersaturated with respect to calcium carbonate having a dissolved calcium and carbonate levels of above 100 ppm.  The calcite producing ingredients are supplied to the water stream in quantities supplementing concentrations available in the natural water used, giving the required supersaturation levels by addition of suitable salts.  The calcite coating can be successfully applied to large diameter mains and pipes by utilizing a large recycle ratio.  The coating has in particular an improved adherence on the wall of the pipes, when the water is delivered at a flow velocity of above 1.5 m/sec.

ABSTRACT                     A device for and methods of measuring and adjusting the convergence of the electron beams in a colour display tube of the shadow mask type.  The device includes a detector in the form of a divided photosensi-tive cell comprising at least two separate photosensitive surface parts which are situated symmetrically relative to the centre of the cell.  The photosensitivity of the sur-face parts increases substantially from the centre of the cell.  In use the device is mounted so that the detector is on the central area of the display screen.  Three lines are produced in one deflection direction of the tube by means of the three electron beams with one video signal. The central line and detector are moved relative to each other until the longitudinal axis of the line coincides with the centre of the cell.  Then either the distances from the axes of the other two lines to the axis of the centre line are measured by determining the differences of the incident light impinging on the two separate sur-face parts and the measurements are stored for subsequent use or the static convergence unit of the tube 18 adjusted until all three lines coincide.  The method is repeated for three line extending in the other deflection direction.
