Abstract: A toilet clog removal device comprised of a collapsible high volume bellows that fits between a toilet seat and the rim of a toilet bowel. When a bellows is compressed with the toilet seat a positive pressure is generated in the toilet bowl and the clogging materials are pushed down. The bellows will also flush most of the water from a toilet, leaving a small amount of water in the toilet bowl allowing a toilet cleaner to be less diluted and thus more effective in cleaning a toilet. After use the bellows may be collapsed by twisting and folding for convenient storage.

Abstract: A multifunctional mechanical display system comprises one or more signboards each having a substantially planar display area with a first bar member that preferably includes a plurality of posts which may be received in any of one or more parallel sets of openings through the signboard to position the first bar member at any of a plurality of parallel, spaced apart positions. Preferably, raised borders around the display area are parallel to the sets of openings and the first bar member and have, with the first bar member, facing sides which are adapted to receive and removably retain therebetween one or more planar, resiliently flexible inserts bearing preprinted indicia. Additional pins are further provided on the rear side of each signboard coinciding with one or more openings through the narrow sides of each signboard to permit the signboards to be joined together into larger signboards, to permit signboards to be mounted back-to-back, or both, through modular support members.

Abstract: Disclosed is a TIG welding apparatus having an electrode connected to a power supply which applies to the electrode a predetermined voltage of either a negative or positive polarity. Control logic controls the electrode polarity to create a welding phase with the electrode at a negative polarity, a cleaning phase with the electrode at a positive polarity, and a momentary power off phase as the polarity of the electrode is switched. An arc initiation unit reestablishes the arc after start up when the polarity of the electrode is switched from a negative and a positive polarity. This arc initiation unit includes a transformer circuit having a primary and a secondary winding, a capacitor, and charging means to charge the capacitor while the electrode is at negative polarity, means to isolate electrically the charging means from the power supply when the polarity of the electrode is positive, and means for discharging the capacitor through the primary winding.

Abstract: An office accessory is used to aid in the organization of incoming and outgoing printed material. This accessory takes the form of a printed material organizer having a flat base extending horizontally in two directions from an upright portion in vertical relationship with a shelf, desk top or the like. A second upright portion, perpendicular to the first upright portion, co-extends with the flat base in one of the two directions to form an open pocket for storing papers or pamphlets. Two of these accessories may be used in tandem to form a three sided pocket or, with one rotated one hundred eighty degrees, to form a closed pocket to store papers or other material that may require support on several sides.

Abstract: Disclosed is a control unit for welding apparatus which feeds wire in the presence of a shielding gas to a workpiece at different rates with different heat inputs in accordance with the wire feed rate. The control unit is designed so that through a single control element the workman may adjust the wire feed rate and simultaneously and automatically adjust the heat input. When different wire types are employed in different welding processes, adjustments in the control unit are provided that allow the workman to reset the relationship between the wire feed rate and heat input in accordance with the type of wire being used. A hot-start feature is provided so that more power is applied for a predetermined manually adjusted time period during start-up.

Abstract: Disclosed is a braking system for a spool of coiled wire used in a welding machine. The braking system includes a spindle mounted to the machine to rotate freely. The spindle has a braking surface and it has mounted to it an annular brake member having teeth around its circumference and a braking surface which engages the braking surface on the spindle. The two braking surfaces frictionally coupled the spindle and brake member together so they rotate as a unit. The braking surfaces slide relative to each other through a predetermined rotational distance when the rotation of the brake member is stopped abruptly. A solenoid actuated pawl engages one of the teeth of the brake member to stop this member, allowing the spindle to rotate through a limited rotational distance of, for example, a maximium of about twenty degrees of rotation.

Abstract: A hand-held and hand-operated gripping device for extracting live rockets from rocket launch tubes is disclosed. The device has the ability to engage and grip an extraction bar extending across the exhaust end of a rocket motor and extract the rocket from the launch tube by a straight pulling action along the axis of the rocket. Jaws of the rocket extracting device are pivotally held on a frame member and are resiliently biased open. The jaws are closed by movement of a separate elongated finger grip bar toward a parallel bar of the frame member while the finger grip bar is in engagement with convergent cam faces of the pivoted jaws. The finger grip bar is captively held in free-floating relationship to the jaws and frame member.

Abstract: A track guided carriage unit for selectively supporting a variety of work performing devices, tools and the like for movement along a predetermined working path, in which a supporting platform has spring loaded wheels that are releasably clamped by a manually operable handle into and out of engagement with opposed surfaces of a guide track, and wherein a motor driven pinion has adjustable meshing relation with a linear rack extending along the track, the pinion being operative to advance the platform at a predetermined rate of guided movement along the work path.

Abstract: Welding apparatus in which a self-propelled wheeled carriage releasably supports a welding gun or torch of the hand-held type having a welding tip and control for controlling feed of a welding wire to the welding tip, wherein the carriage is guided along a joint to be welded at a predetermined proper welding speed, the welding gun being adjustably supported on a pivotally mounted cradle which is power-actuated to provide controlled oscillations of the welding gun and associated tip transversely of the joint at a rate of speed proportional to the propelled speed of the carriage, the amplitude of the oscillations being selectively adjustable between zero and a predetermined maximum. Interchangeable driving wheel units provide for use in the welding of planar disposed surfaces and angularly disposed surfaces.

Abstract: Apparatus for signal selection and signal consolidation of the redundant sensor signals in a triply redundant control system wherein one of the redundant sensors supplies precise information and the remaining two sensors supply less precise information is disclosed. Signal selection is based on the operational state of the three sensors, with the signal provided by the precision sensor being selected whenever the precision sensor is operational. If the precision sensor fails, each channel is supplied with a signal that is a weighted average of the signals supplied by the two less accurate sensors. In some arrangements of the invention whenever the precision sensor has not failed, but supplies a signal that deviates substantially from the signals being supplied by the two less accurate sensors, the signal supplied to each channel of the control system is a weighted average of all three sensor signals.
