Abstract: Abstract Glass sheets are shaped while heat-softened by engaging a surface thereof against an apertured surface of a vacuum mold within a heating fur-nace.  After releasing the glass sheet for further processing, the vacuum mold is removed from the furnace without the glass sheet for cooling and returned to the furnace in sufficient time to engage the next glass sheet to be shaped.  This invention avoids the need to overheat the glass to com-pensate for cooling that occurs when a mold engages a glass sheet outside a furnace to shape the latter without losing control of the maximum tempera-ture to which the mold is subjected during a glass sheet shaping program.

Abstract: Abstract of the Disclosure A gear tooth form is disclosed that maximizes the profile (transverse) contact ratio for coplanar axis gearing.          As the tooth form allows teeth two or three times as fine as those of conventional involute gearing to be used without loss of torque capacity, the face (axial) contact ratio for helical or spiral bevel gearing is also maximized.  The total contact ratio (profile plus face contact ratios) is therefore maximized, and the torque load is divided over the maximum number of teeth. This minimizes the transmission error, which in turn minimizes operating noise and vibration. The gearing employs a minimum pressure angle and a path of contact that includes a curved portion.

Abstract: Z-BAR GUIDE APPARATUS AND METHOD OF BUTT WELDING             Abstract of the Disclosure A method and apparatus for guiding the opposed edges of sheet metal into substantially abutting edge-to-edge relation-ship with one another and thereafter welding said edges by a high energy welding source to form a seam.  The invention enables the continuous high speed butt welding of the sheet metal to form cylindrical bodies.  The apparatus includes three elements which are cooperatively secured in assembled relationship and thereby form opposed and converging guide channels which converge into open relationship with one another along the length of the apparatus so that the opposing edges of sheet metal are guided into intimate abutting edge-to-edge relationship with one another.  The elements extend to a point adjacent the weld zone in order to maintain the sheet metal edges in abutting relationship as they enter the weld zone.         In another embodiment, two of the elements may include portions which extend into and beyond the weld zone.  Such portions are provided with a tapered opening through which the high energy welding source may be continously focused relative to the point of the weld.

Abstract: ACTIVE SEAT SUSPENSION CONTROL SYSTEM                 Abstract of the Disclosure An active seat suspension control system provides for con-tinuous adjustment of the height of a tractor seat in response to movement of a mass within a vibrometer.  The vertical position of the vibrometer mass is coupled to adjust one of a pair of poten-tiometers in a bridge circuit with the other potentiometer being adjusted by the actual height of the seat.  During extreme move-ment of the tractor, the control system is disabled by an arrange-ment which includes a pair of limit switches at opposite extremes of vertical movement of the vibrometer mass and a circuit which effectively uncouples a source of pressurized fluid to a hydraulic cylinder coupled to adjust the vertical position of the seat.          The control system is coupled through the tractor ignition switch to the tractor power supply so as to be disabled except when the ignition switch is turned on.  Following disablement, the control system may be reset by a switch which simultaneously moves a variable resistor defining a gain control within the bridge circuit to a minimum gain position to provide minimum responsive-ness upon startup.  Additional variable resistors in the bridge circuit adjust the stiffness of the control system and the initial height of the seat.  The vibrometer mass is suspended via a cable from the outer end of an arm extending laterally from the free end of a rod having an opposite fixed end so as to provide a desired spring suspension of the mass through twisting of the rod.

Abstract: Abstract of the Disclosure Disclosed is a liquid metering valve unit, particularly for water.  The unit uses a dash-pot mechanism filled with metering liquid such as water, silicone oil or a mixture of water and glycerine.  The dash-pot mechanism is a closed system.  The unit comprises a sleeve member having an axial bore and a transverse bore communicating with the axial bore.  One end of the axial bore connects to a liquid supply and the transverse bore connects to an outlet.  A valve stem in the axial bore is slidable between an open position and a closed position in which a resilient seat washer seals the end of the axial bore.  A spring biasses the stem toward the closed position and the stem can be manually moved to the open position.          Movement of the stem to the closed position is controlled by a dash-pot mechanism or regulating means comprising a cup washer secured to the stem and disposed within a liquid-filled chamber between the stem and sleeve.  The chamber is divided into two portions by the cup washer, which portions are interconnected by passageways within the stem.  One of the passageways contains a compressible wad of porous material and movement of the valve towards the open position causes the cup washer to collapse to allow water to move from the first portion of the chamber to the second portion.  Movement of the valve toward the closed position causes the cup washer to seal the second portion of the chamber from the first and force metering liquid to flow through the compressible wad, which regulates closing time of the valve.
