Title: Controller for adjusting color hue and saturation of images generated from signals in a non-broadcasting video system
Inventor: ECKENBRECHT ROBERT R
IPC: H04N9/64
Filed: 1988-09-13
Granted: 1992-03-31
Abstract: CONTROLLER FOR ADJUSTING COLOR HUE AND SATURATION OF IMAGES GENERATED FROM SIGNALS      IN A NON-BROADCASTING VIDEO SYSTEM    ABSTRACT OF THE DISCLOSURE A color tint controller for a closed-circuit video system receives red and blue color difference signals and selectively changes the amplitudes of these signals to adjust the color of a displayed image.  This is accomplished by changing the levels of the red color difference signals in a first direction, and changing the levels of the blue color difference signals in a second opposite direction, and then adding these changed signals to generate an adjusted red difference signal which is fed into a RGB matrix. At the same time, the levels of the blue difference signals are changed in the first direction and the levels of the red color difference signals are changed in the second direction, and these two signals are combined to form an adjusted blue difference signal which is also fed to the RGB matrix.  The changing of the various color difference signals in different directions is performed in various multiplier circuits responsive to a corresponding set of control signals or multiplier coefficients with which the various color difference signals are multiplied.  The various control signals are generated from a differential voltage created by a control potentiometer.

Granted: 1992-07-21
Abstract: ABSTRACT OF THE DISCLOSURE      Method and apparatus for supporting a liner on an operating string mandrel so that the liner can be lowered into a well bore and selectively rotated and reciprocated.  The liner includes rigid splines which are initially engaged with rigid splines releasably engaged on the operating string mandrel to enable the liner to be selectively rotated and reciprocated before positioning on the well bore casing.  The liner is secured or positioned on the well bore casing and the operating string can then be manipulated to release the mandrel from the rigid splines releasably engaged thereon.  The mandrel rigid splines and mandrel have cooperating surfaces which reconnect the mandrel rigid splines to the mandrel whereupon the mandrel rigid splines can then be disengaged from the liner rigid splines so that the mandrel can be released from the liner.  After the operating string mandrel is released from the liner, the operating string is manipulated to reengage the rigid mandrel and liner splines for rotation of the liner after it has been secured to the casing.

Abstract: ABSTRACT OF THE DISCLOSURE    There is disclosed a solid animal feed supplement which, preferably, is sufficiently hard and water resistant to limit its consumption when free choice feeding of animals.  The solidification of commercial feed solutions of sugars, proteins, or mixtures thereof, for this purpose is achieved by the addition to molasses of calcium oxide or hydroxide and sulfuric or phosphoric acid, a protein meal and a filler, with optional amounts of magnesium oxide or hydroxide.  The filler can be hulls, shells, or screenings of grains of grains and nuts.  The animal feed solution to which these ingredients are added comprises an aqueous solution of sugar or protein or mixtures thereof, preferably molasses.  When a mixture of protein meal and filler is used in amounts from 10 to 40 weight percent of the supplement, and when the proportions of meal to filler are from 0.25 to 4, the amount of magnesium oxide required to achieve a hard solid can be limited to less than 3 weight percent.  In some formulations the magnesium oxide can be entirely omitted, and a hard solid can still be produced.

Abstract: A process for manufacturing calcium silicate and/or aluminate based products, such as Portland cement or aluminous cements. The raw material subjected to a first heating step in which it is heated in a preheater-decarbonator and/or a rotating kiln to a temperature less than that at which impurities, such as alkalines, chlorine and sulfur, are volatized. The heated raw material is then subjected to a second heating step in the presence of a reducing gas, preferably in a plasma furnace, the raw material being heated to a temperature higher than the temperature at which the impurities are volatilized, as for example above 1950 DEG  C., and more than 80% of the material is in fusion, whereupon the material is cooled to produce the clinkers of improved quality and/or with lower energy consumption. An important feature of the invention is the utilization of the gases generated during the second heating step and during cooling to implement heating of the raw material. It is equally important, however, that the gases generated during the second heating step are not utilized to heat the raw materials unless such gases are first purified.

Abstract: This invention relates to the mechanical and environmental protection of cable joints, especially in power or other current-carrying cables. Disclosed is a recoverable sleeve which conforms closely to the cable joint, and a liner which bridges the joint and comprises a plurality of elongate elements assembled into a sheet. Flexible means is provided for holding the elements in a side-by-side arrangement and allowing the separation between the elements to vary to allow the liner to conform to the profile of the cable joint. Such flexible means may extend across the element and provide a water vapour barrier. Disclosed also is a method of protecting a cable joint utilizing the sleeve and liner. Where the cables to be jointed have metal armor, screen and/or shielding, the elements may be fabricated from metal or metal alloy and may then provide both armoring and a fault current path across the joint. Use of these more closely conforming joint case assemblies improves heat transfer and reduces the overall size of the joint.
