Abstract: A tubular band of pre-decorated heat shrinkable material is positioned over the bulbous or central portion of a seasonal ornament and the ornament-band assembly is then subjected to a heat source and the band is permanently shrunk onto the outer surface of the ornament, thus providing a surface decoration therefore.

Abstract: A mold mechanism for opening and closing a split mold is described wherein a single air cylinder moves one half of the mold in a linear direction and simultaneously, through a plurality of interconnected pivotal links, rotates the other half of the mold through an arc of at least 90 degrees so as to open and close the mold halves upon actuation of the air cylinder.

Abstract: Neck ring apparatus is disclosed for retaining and conveying glass along a predetermined path as the glass is transformed from an initially formed parison to a final blown glass article having a desired finish. A pair of sprockets, forming a part of the neck ring mechanism, selectively engage roller tracks as the mechanism proceeds along its predetermined path to (1) open segments of the neck ring so as to permit the delivery of a charge of molten glass to a mold position therebelow, (2) to close the neck ring segments so as to form a finish on an initially formed parison and retain such parison by said finish, (3) rotate the neck ring and accordingly said parison for uniformly cooling the parison and for removing blow mold seams during the blowing of the final article, and (4) to open the neck ring segments to remove the finished article therefrom.

Abstract: A single mold and plunger set is programmed to form a parison within each of a plurality of neck rings which are continuously successively presented along a linear path. The mold, which is positioned below the linear path of said continuously successively presented neck rings, receives a charge of molten glass and accelerates in a direction parallel to said linear path to a speed commensurate with that of the continuously presented neck rings, and upon tracking with a particular neck ring, such mold moves vertically into engagement with a bottom portion thereof. Simultaneously, the plunger, which is positioned above said linear path, accelerates in a direction parallel with the movement of said continuously presented neck rings to a speed commensurate therewith, and upon tracking said particular neck ring moves vertically into engagement with an upper portion thereof so as to press form the charge of molten glass deposited within the mold into a shape determined by the shape of the parison mold and plunger.

Abstract: A method is disclosed for pressing and blowing a hollow article wherein a soft blank having a cavity is press formed which may require only minimal surface reheating prior to the blowing of such blank into a finished hollow article. At the completion of the press forming, the core temperature of the soft blank is substantially equal to the delivery temperature of the charge from which the soft blank is formed.

Abstract: An induction coil heating device is provided to proximately heat an aperture mask support pin in a relatively confined space in the corner of a television panel skirt. A primary coil adapted to receive alternating current power is wound about at least one insulating support member. The primary is loosely wound in a central axial area thereof to provide an annular space, and a secondary coil with a spaced away outrigger output loop inductively coupled to the primary is wound around said support member in the space provided by the primary. The output loop is adapted to receive electrical energy for heating the support pin in response to input energy provided via said primary coil. The output loop is spaced away from the primary and sized so as to be readily insertable in the confined space of the corner of the panel skirt.

Abstract: There has been provided a television tube having funnel, panel, and neck portions fused together in a conventional manner. A controlled failure zone in the form of a circumferential implosion protection notch is formed in a rearward portion of the funnel for establishing a stress concentration location, such that, in the event of a destructive impact to the panel, the tube will crack along the notch in the controlled failure zone and reduce the implosion potential of the tube.

Abstract: Plastically formable material, which may be formed under pressure into desired shapes, is fed while in a fluid or plastically formable condition to a pair of cooperating surfaces which are relatively movable into compressive relationship with material disposed therebetween. The face of at least one of such surfaces is patterned with a plurality of juxtapositioned geometrical impressions of desired size and shape so as to form a ribbon or sheet of uniformly sized and shaped particles from the plastically formable material supplied to the cooperating surfaces. The uniform particles are initially joined together by thin web or edge portions which maintain the continuity of the newly formed particles within a sheet form.

Abstract: The present invention provides a surgical cutting instrument having a blade portion and cutting edge therefor with electric input elements located near the cutting edge for cutting the tissue and cauterizing the surfaces of the incision, thereby allowing surgery to be more rapidly performed. This is accomplished in accordance with the illustrated embodiments of this invention by providing electrodes of opposed polarity, applied to the blade, near the cutting edge. With an electrical potential applied, no current will flow between the electrodes and no heat is produced unless the electrode gap is bridged by a conducting medium such as a high conductivity physiological liquid from the incision. Heat is then generated by electric discharge below an arcing threshold in all areas where the blade is in contact with moist tissue. No electric discharge or heat occurs elsewhere.

Abstract: In the encapsulation of insert materials within glass and glass-ceramic articles, not only must the bonding characteristics between the insert and the glass or glass-ceramic materials be considered, but also the relative coefficient of thermal expansions between the insert and the encapsulating materials must be programmed in order to avoid undue stresses in the article or the insert which could produce deleterious results.

Abstract: In an apparatus for conditioning a supply of molten thermoplastic material, preferably glass, a chamber in flow communication with the supply of glass is mounted for rotation about an axis. The chamber has a flow control surface having at least two regions, each uniquely oriented for influencing the flow of the molten glass therealong. In one region the glass experiences delayed flow to enable it to give up heat and in a region downstream of the first, the glass experiences accelerated flow to enable it to counteract changes in viscosity resulting from previous heat loss. The chamber is rotated so that a fresh supply of glass at an elevated temperature is deposited circumferentially on the flow control surface in order to moderate the influence of heat loss as the glass flows through the chamber.

Abstract: A spray dryer apparatus is used to bring a water solution or slurry of finely-divided, basic reactant into intimate contact with a flue gas bearing acidic gases or vapors. The basic material reacts with the acids in the flue gas to form a particulate precipitate, while the water from the solution or slurry is fully evaporated in the gas stream. Conventional means are then utilized to remove the particulate reaction product from the flowing gas stream.

Abstract: There has been provided a television tube having a funnel, panel, and neck portion fused together in a conventional manner. A circumferential implosion protection controlled surface discontinuity is formed in a rearward portion of the funnel for establishing a stress concentration location near a point of maximum stress therefor, such that in the event of a destructive impact to the panel, the tube will crack along the controlled surface discontinuity and reduce the implosion potential of the tube.
