Abstract: A method and apparatus for cutting pattern shaped holes in glass sheets is disclosed in which a pair of continuous parallel lines are scored on the upper surface of a glass sheet in horizontal orientation so that the outermost score line defines the periphery of the pattern hole. A pair of templates having opening coincidental but smaller than the pattern hole is clamped on both the upper and lower surfaces of the glass sheet so that the outermost score line is located between the clamped plates while the innermost score line is exposed. A force is applied to the exposed area of the glass sheet to remove the glass from the pattern hole. The glass severs at both the inner and outer score lines to produce the pattern shaped hole. Breakout is additionally assisted by thermal gradients introduced in the glass sheet by applying opposing moments to the glass.

Abstract: A container for shipping sheets is disclosed in which there is provided a horizontal base and a vertical backwall. The sheets are stacked on edge on the base and supported in position by the vertical backwall and a plurality of diagonal bands running from the top of the backwall to the front of the base. Methods of loading and unloading the container are also disclosed.

Abstract: The present invention relates to shaping and tempering glass sheets using a pair of cooling stations and an access area with a common tunnel-like furnace and a common shaping station. The cooling stations are located near the common glass sheet shaping station along angularly diverging paths of movement from said shaping station so that a first cooling station for chilling a glass sheet bent about an axis of curvature approximately parallel to its initial path of movement through the furnace is located along an extension of the path and a second cooling station for chilling a glass sheet bent about an axis substantially normal to the path of glass sheet movement through the furnace is located to one side of said shaping station and said access area is located to the other side of said shaping station. The access area permits ready change of shaping molds at the shaping station.

Abstract: Damage-free scores are initiated by engaging a scoring wheel to the surface of a refractory piece with the plane of rotation of the scoring wheel forming an oblique angle to the desired path of damage-free scoring. An aligning force generated by the interaction of the scoring wheel and the refractory piece during relative movement along the desired scoring path pivots the scoring wheel into alignment with the desired path of scoring, which pivoting creates a zone of surface damage which serves to initiate a damage-free score. Facilities are provided to urge the scoring wheel out of alignment with the desired path of scoring, with a magnitude of force less than the aligning force, such that the scoring wheel automatically returns to a pivotally offset initiating position when it is disengaged from the surface of the refractory piece.

Abstract: A damage-free score is initiated in a moving ribbon of glass by projecting grit material toward the surface of the ribbon in a controlled manner to create a selected zone of surface damage thereon. The selected zone of surface damage is then advanced under a scoring wheel sized, shaped, and loaded to generate the damage-free score upon encountering an appropriate zone of surface damage.

Abstract: Apparatus for providing a plurality of particles of grit material onto the surface of a refractory piece to be damage-free scored, whereby the entrapment of a particle of grit material between a biased scoring wheel and the surface of the refractory piece generates a zone of surface damage which initiates a damage-free score.

Abstract: Damage free scores are initiated in a refractory piece by advancing a pattern of grit material on the surface of the refractory piece under a properly biased scoring wheel. The grit material is preferably harder than the surface of the refractory piece but not as hard as the scoring surface of the scoring wheel.

Abstract: A plurality of lights are mounted relative to one another to direct light beams toward a glass sheet along continuous scan portions. The sheet moves through the scan portions to reflect light beams toward a linear array of diodes. The linear array of diodes is activated and deactivated to simulate a discrete scan path and to generate points of intersection between the edge portions of the glass sheet and the scan path. The signals of the photodetectors are acted on to determine peripheral characteristics of the sheet such as squareness of the corners, linearity of the sheet sides and length of each sheet side.

Abstract: Continuity of antenna wire of an antenna windshield is determined by mounting two electroconductive receiving plates in space relationship to one another and to an electroconductive transmitting plate. The receiving plate and transmitting plate are positioned over and spaced from segments of the antenna wire. The transmitting plate is energized to form capacitors or capacitance couplings (1) between segments of the antenna wire and the plate and (2) between the receiving plates and transmitting plates. The potential difference between the receiving plates is measured to determine wire continuity.

Abstract: This invention relates to a stop adapted for attachment to outline molds of different outline configurations defining shapes of different depths of bend desired for glass sheets to be shaped to different patterns. The stop comprises a glass engaging member of disc-like configuration having a front surface oriented to face an edge surface of a glass sheet to be mounted in engaging relation to said front surface when loaded onto a selected one of said outline molds. The glass engaging member of disc-like configuration is supported in eccentric relation to a rod supported in fixed relation relative to a localized portion of an upwardly facing shaping surface defined by a shaping rail of said selected outline mold.

Abstract: Nozzles are arranged in different densities transverse to a path of travel for glass sheets moving through a pass-through quench to facilitate removal of spent tempering medium to both lateral sides of said path of travel.

Abstract: An apparatus for dispensing material in measured amounts, primarily for use in the treatment of livestock is disclosed. The apparatus provides a material containment cylinder having a nozzle at one end and a diaphragm attached to a rod at the other end and a mechanism for precisely controlling the movement of the diaphragm so that precise dosages are dispensed through the nozzle end. A bayonet locking attachment for affixing the material containment cylinder to the diaphragm movement mechanism is also disclosed. A number of embodiments are provided for precisely controlling the diaphragm movement mechanism including a slideable rod friction attachment and ratchet and stop mechanisms.

Abstract: A waterbed mattress with one or more open-celled foam members used for dampening wave action in the water is disclosed. The foam members are supported by the buoyant force of the water and require no attachment to the surface of the waterbed mattress bladder. A vacuum means for evacuating air from the bladder and the foam member after the bladder has been drained of water is also disclosed.

Abstract: A heat recapture device for attachment to a furnace or fireplace exhaust flue is disclosed. Duct work in the device allows ambient air to be warmed by combustion exhaust gases. Air thus heated may be used to heat the surrounding living space. Additional duct work causes circulation of fresh air into the room and serves as a heat insulating shield around the periphery of the device.

Abstract: An apparatus for the heating of ambient air within enclosed chambers in the walls of a fireplace, providing a more efficient means of utilizing the heat radiation produced by a fireplace and also to provide fresh warm air for heating purposes throughout a home is disclosed.Cold ambient temperature air is forced into the system by a two-speed fan through a cold air conduit into the outer chamber of the fireplace apparatus. The air is forced up the outer chamber to the top of the chimney where it crosses over to the inner heating chamber and the diagonal duct located within the flue space of the chimney. As the air progresses down the inner warm air passageway and the diagonal flue duct, it is heated by conduction through a metal wall in contact with the hot gases produced by the fire. The air then is forced down through these passageways into the rear and sides of the firebox. The air is fed thorugh a manifold grating under the fire, and then collected in the hot air plenum located at the base of the firebox.
