Abstract: ABSTRACT       Electrical and elctric component are temporarily stabilized in pre-determined position on a circuit board with their leads extending through holes in the board, by means of a selected, solid, solder-compatible material which couples the leads and the board to one another.  The material preferably is one which does not decompose at soldering temperature, but instead should have a melting point or liquidus temperature below that of solder.          The component leads may then be trimmed to finish length with the components in position on the board, and the components may then be soldered in place in a single soldering step using known techniques.  The stabilizing material is melted and displaced simultaneously with the soldering.  In a preferred embodiment of the invention compatible flux active agents are admixed with the stabilizer material.

Abstract: ABSTRACT OF THE DISCLOSURE     In a laminated magnetic core wherein an adhesive is utilized to secure laminations in a unitary structure, low core compressibility is obtained by restricting the distribution of ad-hesive so that regions of metal-to-metal contact which surround axial compression points are kept completely free of adhesive.          The core is formed by placing the laminations in assembled relation and applying a limited amount of the adhesive in a liquid state to selected core surface areas.  Isolated interlaminar regions which lie intermediate of the axial compression regions are filled by the adhesive which flows therein by capillary action.  The quantity of adhesive applied is carefully controlled so that capillary migra-tion is contained wholly within the isolated bonding regions.

The purified organic liquid stream is monitored for indicating when the selective cleaning of the bed is required. The electrofiltration system, both in a novel electrofilter and process, produces without aging a new organic liquid product having comparable properties to multistep processed prior art organic liquid.

Abstract: ABSTRACT OF THE DISCLOSURE    A novel automatic gray scale control circuit is provided for a color television receiver having a three-gun cathode-ray tube.  The circuit senses the cut-off voltage of each gun during the blanking interval, and uses a voltage equal to the cut-off voltage to energize the driver and bias the gun during the video field.  The effect is to standardize the emission of each of the three guns against variation in gun cut-off voltage and to produce improved gray scale accuracy at the lowest emission levels.  Since the gray scale adjustment is otimized at the lowest emission levels, where the eye is most intolerant to error in hue, one may avoid the need for manual adjustment of the cut-off point, and in cases where the gain does not vary widely from gun to gun, avoid the need for separate gain adjustment.  Thus, the circuit may be used either to simplify or eliminate the color set up process at the factory when the receiver is manufactured.          It may also reduce or avoid the need for readjustment after periods of use.
