Abstract: The invention provides a process for producing a transparent optical-glass body having a linear index of refraction gradient. Particles of optical glass which contain leachble ingredients are pressed to form a self-supporting porous optical glass body. Some of the leachable ingredient is leached from a part of the porous glass, and a different amount is leached from a second part of the porous glass, the index of refraction varying in proportion to the different amounts leached from the glass body. The porous optical glass body is heated to eliminate the pores. Various means for effecting the different amounts of leaching over the length of the glass body are shown.

Abstract: A glass-ceramic plate cooking surface comprises a glass-ceramic base layer which allows penetration of thermal radiation having a wave length of from 0.7 to 5 microns and a top covering layer smaller in thickness than the base layer which is tightly joined to the base layer and absorbs the radiation with wave lengths of 0.7 to 5 microns. The glass-ceramic plate cooking surface can have the heating areas indicated by design and can be provided with an additional layer to avoid asymmetric stress and strengthen the cooking surface.

Abstract: An apparatus for treating a web of material of indefinite length consists of a generally rectangular chamber having a single opening at the top and a screen arranged within the chamber to asymmetrically sag in a shape of approximately elliptical cross-section and means for introducing a web treatment medium into the chamber. This apparatus is advantageously combined with a flow-through reversible drum treatment chamber having within a casing a periodically reversed rotating drum through which a web of material is received in the relaxed state travelling continuously through the interior of the drum and means for controllably conditioning air and introducing the air into the drum.

Abstract: A layered composite batt consists of a plurality of layers, each layer having a series of overlapped, cross-laid webs of fibers. The fibers forming the webs, the webs, and the plurality of layers are bonded to one another to form the composite batt by a melted and resolidified copolymer. The process used in producing the composite batt comprises producing a plurality of open webbed fibers, dispensing particulate copolymer on to each open web of fibers, reciprocatively layering each web and the particulate copolymer carried therewith to form a layer having an upper and a lower face, arranging the layers thus formed such that each layer produced is in face to face contact with at least one other layer thereby forming a plurality of layers, and heating the plurality of layers to a temperature above the melting point of the copolymer but below the scorching point of the fibers.

Abstract: Color balance of a color television picture is corrected during those periods when the luminosity falls within prespecified limits and when simultaneously the chroma-saturation is below a prespecified level. A switch operates to change the time constant of an integrator for derivation of a control signal indicative of when the simultaneous conditions are met. One time constant is used when the simultaneous conditions begin and another when they end, thereby allowing better correction of color stains which do not extend uniformly over the entire picture.

The means for inhibiting secondary emission comprises outwardly extending wedge-shaped members covering the inner walls of the vacuum chamber. The outwardly facing surfaces of the wedge-shaped members are covered with a nonevaporable getter metal.

Abstract: A relatively simple and highly efficient safety system for retaining the tires, which are mounted on the front wheels of heavy, over-the-road vehicle such as trucks, buses and the like, in the event of gradual or sudden deflation of the tires. Such tires are locked onto rims of the two or three-piece types, mounted on disc or spoked wheels. The important and essential features of the present invention reside in the provision of a radially - extending locking lug detachably mounted on and rigidly secured to a spoke of the wheel or in the ventilating holes in disc wheels and which terminates at its outer end in a position to contact the outer flange of a two-piece rim installation, or in the case of a three-piece rim installation, to contact the outer flange and to overlie the radially-split locking ring.

Abstract: A valve for controlling the flow of air and liquid product mix from a liquid product reservoir to a freezing chamber in a soft ice cream dispensing machine has a lower tubular member snugly yet removably received within a tubular communicating line between the reservoir and freezing chamber. An air retaining chamber is fixed to the upper portion of the lower tubular member and communicates therewith. An upper tubular member fixed to the chamber extends upward to a point above the maximum anticipated level of the liquid product in the reservoir. The lower end of the upper tubular member extends somewhat inside the chamber. The upper tubular member has a small aperture near the lower end thereof opening into the liquid product reservoir. A checkvalve is attached to the lower end of the upper tubular member for retaining air in the air retaining and freezing chambers to assure the desired overrun in the ice cream.
