Abstract: AMBIENT PRESSURE SENSOR                       ABSTRACT OF THE DISCLOSURE An ambient pressure sensor generates an electrical signal which varies in response to changes in ambient pressure level.  The sensor includes a sealed bellows or aneroid which varies in length as the ambient pressure varies.  A fluid motor including a piston slidably mounted within the housing carries a tube which extends to a position adjacent one end of the aneroid.    The end of the tube defines a valve seat which cooperates with a valve member carried on the end of the aneroid to control communication of atmospheric pressure through the tube and into the power chamber defined between the piston and the end of the housing.  The power chamber is connected with a vacuum source, so the atmospheric pressure communicated through the tube varies the pressure level in the power chamber as a function of ambient atmospheric pressure, since the aneroid controls communication through the tube.  Consequently, the piston and tube move relative to the housing as the ambient pressure changes.  A potentiometer includes a wiper which is carried by the tube.  The wiper is moved along a resistance within the potentiometer, to thereby generate an electrical signal which varies depending upon the position of the tube.

Abstract: ABSTRACT      The Present invention relates generally to raise type earth boring drills and, more particularly to such raise drills having shock elements for absorbing impact type loads passing through the drill. During a raise drilling operation, a tremendous amount of wear and stress is imposed upon the drive stem of the raise bit. Because of this wear, many raise drills have the drive stems replaceably mounted on the bit body, thereby extending the useful life of the bit.  Addi-tionally, an elastomeric shock element may be added for absorbing the impact type loads passing through the drill.  However, with the utilization of such a component, the drill bit body is relatively movable with respect to the drive stem.  As a result, the inboard cutters, which are normally connected and anchored to the drive stem for stabilization and load bearing purposes, cannot now be anchored to the drive stem and still have the bit body flexibly mounted,  The present invention obviates this inboard cutter stabilization problem by providing a central yoke extending around the drive stem which interconnects the saddles of the two innermost cutters.  The primary advantage of the present invention is that any uneven loading acting on one of the inboard cutters can be transferred to the other via the central yoke.

Abstract: LINE SPACING AND COLUMN FORMAT CONTROL SYSTEM               Abstract of the Disclosure A system for printing a plurality of sequentially stored text columns in a side-by-side format with the line spacing of one column varying from that of another. Each column is to be printed out in an operator defined location.  After a line from one of the columns is printed on a print line in a defined location, the carrier is caused to escape.  Any corresponding lines from succeeding columns, as determined by their line spacing requirements, are printed on the same line prior to causing a printer carrier return.  That is, the line spacing requirement of a column is utilized to determine whether a line from the column is to be printed on the print line being printed.

Abstract: METHOD OF MAKING FRANGIBLE SEAL                       David A. Winchell Thomas A. Fowles ABSTRACT OF THE DISCLOSURE         A method is provided for forming a fracturable seal of the type wherein a plastic cup-shaped closure is hermetically sealed to a plastic planar surface, such as the neck of pharmaceutical solution containers.  The seal is formed with the closure by forcing a die heated above the melting point of the plastic material into the planar surface, with the sealing die also being in heat exchange relationship with a portion of the closure.  Both the planar surface and the closure adjacent thereto become molten and the surface material is displaced to form a fused seal transverse to the surface.  The surface is depressed at least 0.005 inch from its original height by the sealing action of the die, and a frangible section is formed in the vertical side wall of the depression.          The seal will be fractured due to tension stress when the closure is removed from the surface.

Abstract: FAIL-SAFE GAS FEED AND IGNITION SEQUENCE CONTROL APPARATUS AND METHOD      FOR A GAS-FIRED APPLIANCE     Abstract of the Disclosure A fail-safe apparatus and method for controlling the sequence of gas feed and ignition, such as by an incandescent igniter, in a gas-fired appliance, such as a thermostatically controlled timer activated clothes dryer.  When the appliance is activated by the timer, the control apparatus energizes the igniter and opens a gas valve only after the igniter is energized for a period that is sufficient to heat the igniter to the tem-perature required to kindle the gas.  If the gas is ignited, the control apparatus holds the gas valve open so that the gas con-tinues to burn.  If, however, the gas is not ignited, the control apparatus inhibits any further attempt at gas feed and ignition.          If a temporary electrical power outage occurs, if the gas supply is interrupted, if the thermostat cycles on and off,or, in the case of a clothes dryer, if a loading/unloading door is opened and then shut again, the control apparatus repeats the gas feed and ignition sequence in an attempt to rekindle the gas.

Abstract: ket M-318 TAG ATTACHING APPARATUS Abstract of the Disclosure There is disclosed apparatus for attaching tags using fasteners of a type having a bar section and a button section joined by a filament section.  The apparatus includes a body with a pair of body sections keyed together in part by a needle having an elongated bore and a side opening.  A push rod is engageable with the bar section to push the bar section through the needle bore while its filament section extends through the slot.  Opposed operating levers are pivotally mounted on opposite sides of the body.  Each lever carries a cam.  A first carrier is mounted by the body and a second carrier is mounted by the first carrier.  The push rod is connected to the second carrier.  The first carrier has a pair of carrier members and each carrier member carries a post which rotatably mounts a gear.  The carrier members are connected by a pin which rotatably mounts a pair of rollers.  Each cam cooperates with a respective roller.  A rack is secured to each body section and the second carrier has a pair of racks.  Each gear meshes with a respective body section rack and a respective second carrier rack.  A pawl is coupled to the first carrier through a lost-motion connection so that only part of the movement of the first carrier is imparted to the pawl.  Action of the operating levers causes the cams to drive the rollers to in turn drive the first carrier.  Movement of the first carrier causes the racks and gears to drive the push rod forward through a distance Docket M-318 twice as great as movement of the first carrier.  Near the end of the forward movement of the push rod, the pawl is moved to a ready position.  A spring acting on the first carrier returns the carriers, the levers and the push rod to their respective initial positions and moves the pawl away from its ready position to drive a toothed wheel of a fastener advancing means to bring a bar section of the next successive fastener into alignment with the needle bore.  The pawl is cooperable with a cam disposed at a preselected position so that the toothed wheel with which the pawl cooperates can be driven through a preselected angle.
