Abstract: A fluorine-free glass composition is disclosed especially adapted for forming the faceplate of a cathode ray tube such as a television tube. The glass is silica based and includes a fluorine-free flux and an X-ray absorber which may comprise lead oxide, barium oxide, strontium oxide, and mixtures thereof. Optionally, the glass may contain still other oxides to impart desired physical properties. The absence of fluorine avoids the usual problems of that ingredient in melting and processing the glass. In addition, the resultant glass as a faceplate provides improved protection to a viewer of a cathode ray tube by excellent absorption of X-rays.

Abstract: A fabricated cup or other container in which the sidewall is formed from a rectangular sheet-like blank of an oriented thermoplastic material, the blank having its ends joined to one another to form a cylindrical sleeve with a liquid-tight seam, the blank having a relatively high degree of orientation extending circumferentially of the sleeve, the fabrication of the sidewall from the sleeve being accomplished by telescoping the sleeve over a substantially cylindrical mandrel, by exposing the sleeve to heat to cause it to shrink into conformity with the external configuration of the mandrel and by completing the cup by pressing the bottom and forming a beaded rim.

Abstract: A mechanism for dispensing container closures, one at a time, from a stacked array. A hand operated slide bar is positioned at the bottom of the closure stack. An upturned edge or finger is attached to the slide bar, thus enabling it to engage with the inside rim area of the closure and pull the closure from the stack. The finger on the slide bar is beveled so that it will slide beneath the container rim when the slide is returned to its inward position.

Abstract: Halftone printing of a plurality of different colors is employed to produce a composite graphic display on the surface of the glass. Precise alignment is utilized in order to register the halftone printing screens for each color that is deposited on the glass surface. The opaque enamels employed in the decorative process are carefully balanced with respect to each other to obtain the desired color hues. The deposition angles for the alignment of the halftone dots is controlled to minimize the undesirable moire effect.

Abstract: Apparatus for forming the rim on a foam plastic container such as a cup by use of a segmented rim former. The cavity in the rim former is contoured so as to produce a curled rim that is flat on the top. The flat top of the rim is parallel to the bottom of the cup.The apparatus comprises a segmented rim former with a combination of linear and curved surfaces that form a noncircular container rim.

Abstract: A mandrel for forming a container made of foam plastic sheet material. The mandrel defines the internal configuration of the container and also is used to form a rim on the top edge of the container. The container rim is formed by first expanding the rim in diameter by means of cam actuated segments which extend radially outward from within the confinement of the mandrel structure. Subsequent to the diametrical expansion of the rim, the container, including the exterior of the mandrel, undergoes a translation along the mandrel longitudinal axis, thus causing the container rim to fold back upon itself, thus forming a lid receiving bead.

Abstract: A device for aiding in the preparation of very thin slices of foam sheet material that is to be examined under a microscope. The device has a clamp arrangement for holding a sample of foam sheet material. A screw feed arrangement permits the foam sheet material to be advanced past a planar surface where a very thin slice of foam material can be removed. A clamping arrangement keeps the foam sheet material in linear alignment at the location where the sample is severed. A detent arrangement permits a metered amount of foam sheet material to be advanced past the planar cutting surface by the screw feed arrangement.The method of preparing a foam sample by first severing the foam material while it is held by the apparatus, thus establishing a planar cut, then positioning the material for a second cut which is then made parallel to the first cut.

Abstract: The disclosure relates to a cathode ray tube for colored television. A shadow mask is employed within the tube and is held in fixed position interiorly of the tube faceplate. The shadow mask is held in position by anchor pins positioned within the four corners of the faceplate. A method has been devised whereby the shadow mask is permitted a certain degree of flexibility, thus permitting the surface of the shadow mask to follow the curvature of the interior surface of the faceplate. The method encompasses fixing three of the shadow mask support points within the faceplate to define a reference plane, then gauging the distance from the established plane to the interior surface of the faceplate so that the fourth shadow mask support point can be positioned in its optimum position to minimize any errors in the distance between the surfaces of the shadow mask and the interior of the faceplate.

Abstract: A closure dispensing apparatus for dispensing closures one at a time from a stacked array. A crank mechanism pivoted at its center for rotation with a plurality of handles in radial alignment with the pivot point. The crank mechanism is positioned beneath the stack of closures so that movable lugs which are attached to each handle can one at a time interact with the rim of the bottommost closure in the stack and pull it from the apparatus. An inclined plane arrangement is used to cause each lug in its proper sequence to move into and out of a closure rim engaging position.

Abstract: Disclosed is an apparatus and method for controlling the position of a stepping motor which is driven by a buffered translator. Commands calling for either forward or reverse motor steps are sent to the buffered translator, and the motor subsequently executes these commands. In order to determine if the motor executes all of the commands sent to the buffered translator, a signal representing the position the motor would assume if all of the commands were executed is compared to a signal representing the actual position of the motor. If they do not correspond, additional command pulses are caused to be generated to the buffered translator until the desired motor position is achieved.

Abstract: A machine for testing a container such as a paper or plastic cup. The cup rests upon a platform and its stiffness is measured by applying a given load to the side of the cup by means of a motor driven load applying arm. The applied load and the resulting deflection are determined by the direct coupling together of the cores of a force cell and a linear variable displacement transformer. The load applying arm and the coil of the linear variable displacement transformer are coupled together to compensate for an initial preload condition. The ultimate load for the predetermined deflection is monitored by a force cell and the electrical signal thus generated is converted to a direct reading digitally displaced valve.A method for testing a cup-like container by supporting the container on a set of rollers and applying a first small force normal to the side of the container. A second greater force is applied to the side of the container until a preselected overall deflection of the container side is attained.

Abstract: A process for forming organopolysiloxanes from trialkoxysilanes and the resulting resinous products are disclosed, characterized in that the organopolysiloxane resins have increased abrasion and solvent resistance with good shelf life. The organopolysiloxanes are formed by dual catalysts that operate preferably in sequence. Hydrolysis and condensation of the trialkoxysilanes are carried out in an aqueous solution and catalyzed by formic acid at a relatively high strength, such as an amount greater than 700 ppm. Cross-linking of the resulting partially condensed, curable organopolysiloxane is then catalyzed by a hydrocarbyl substituted ammonium hydroxide in which the hydrocarbyl substituent may be alkyl or alkenyl up to about 6 carbon atoms. The resinous products are especially useful as coating compositions.
