Abstract: ABSTRACT OF THE DISCLOSURE          The stair-climbing device is suitable for transporting a load up or down a flight of steps.  The device includes a frame on which the load is seated and a number of load bearing shoes which engage successive steps in the flight of steps to produce displacement of the device along the flight of steps.  The shoes are pivotally connected to sprocket chains which are activated by a reversible electric motor.  An arm is pivotally connected to the frame and is provided with a sensing head disposed forward of wheels on which the device rolls.  As the device rolls forward on the tread of a step, the sensing head contacts the tread until it is beyond the forward edge whereupon the head falls with resulting pivotal movement of the arm.  The arm is further provided with a downwardly facing friction surface which is spaced above the tread when the sensing head is in contact therewith and which descends into contact with the tread when the arm pivots and thereby frictionally retards further forward movement of the device on the tread.

Abstract: ABSTRACT OF THE DISCLOSURE       The temperature recording instrument contains the usual thermal measuring system consisting of a bellows assembly, a temperature sensitive bulb and capillary tubing between the bellows and bulb and a recording system including a marking ele-ment which is responsive to the energization of the bellows for permanently indicating the temperature sensed by the bulb on chart paper mounted on a base plate located in the instrument housing.  A fulcrum having an axis extends through the base plate and carries a bracket which is provided with one slot or with a pair of slots on opposite sides of the axis.  A spool is located in one or the other of the slot?.  An adjusting screw is carried by the bracket and is threadedly connected to the spool.  Rota-tion of the adjusting screw is effective to move the spool in the corresponding slot relative to the fulcrum's axis.  The marking element is located on the chart side of the base plate and is secured to the bracket.  The bellows includes a movable element engageable with the spool.  Energization of the bellows is effective to move the movable element which engages the spool and rotate the bracket about the fulcrum resulting in the movement of the marking element in one direction across the chart.  If a second slot is provided in the bracket, the spool may be located therein, with the movable element of the bellows engaging same to effect rotation of the bracket and the movement of the marking element in the opposite direction across the chart.

Abstract: INTERFOLDING APPARATUS                      Alson R. Harm ABSTRACT          An apparatus for simultaneously folding and interfolding a multiplicity of webs of flexible material such as facial tissue paper in the machine direction to form an endless bundle of interfolded webs which endless bundle can be cut into discrete bundles and packaged in pop-up dispensing containers.  The apparatus comprises a fan-shape, horizontally disposed folding table comprising a set of tapered elongate guides having inverted V-shape cross sections. The elongate guides are disposed in side-by-side relation and thereby form tapered V-shape troughs there-between.  The webs are directed in convergent relation onto the radially outwardly disposed edge of the fan-shape table in partially overlapped relation and are drawn radially inwardly thereacross and thence about a turning guide whereupon the folds of the webs are alternately V-folded upwardly in said troughs and downwardly about the ridges of the elongate guides so that an edge fold of each web is disposed intermediate two folds of an adjacent web.  The apparatus may also include an array of unwind backstands, and ply bonding and machine-direction slitting devices so that the multiplicity of webs can be supplied from a sub-stantially smaller number of parent rolls.

Abstract: ABSTRACT          Overload protection of a three-phase submersible pump motor, such as the type used downhole in an oil well, is obtained with a solid state digital logic control system that monitors each of the three phase currents and shuts the pump motor down if any of those phase currents indicates an overload condition.  A time delay is introduced before shutdown to avoid undesired nuisance shutdowns other-wise caused by transient or momentary conditions.  The shut-down time delay is variable and is inversely proportional to the amount of overload in order that greater overloads result in faster shutdown.

Abstract: ABSTRACT OF THE DISCLOSURE    A mechanical and electronic apparatus for integrating gas flow charts for determining gas volume.  The mechanical apparatus includes a motor driven disc on which a recorded flow chart can be placed, with suitable pen arms, and operating arms, so that an operator can simultaneously vary the angular position of each of two pens, so that the pens may trace or scan simultaneously, the two recorded traces of pressure and differential pressure, as the disc and chart rotate under a motor drive.  Optical encoders convert the rotation of the disc and the angles of swing of the pen arms to digital values.  The outputs of the encoders are scaled to the particular charts and chart arms.  The result of the scaled pulses go to an up/down counter for interpretation of total angle of each of the pen arms.          The digital numbers representing the angles of the two pen arms then have their square roots extracted, the two outputs of square roots of pressure (P & A) and differential pressure H go to a multiplier and an accumulator.  The output then goes to a display register or to a printer.

Abstract: CONTROL MECHANISM FOR REMOTELY MOUNTED MOTOR              Abstract of the Disclosure A control mechanism for a remotely mounted motor, such as an antenna rotator, is contained within a molded housing having a cover and base, and includes an indi-cator motor which rotates a switch assembly to a pre-selected location.  The switch assembly is operated by a manually positionable dial having a knob accessible through an opening in the housing cover.  The dial in-cludes a cam surface which actuated the switch mecha-nism to control the direction of rotation of the motor and the repositioning of the switch to the manually selected direction.  The tendency for the dial mechanism to rotate as the switch means is repositioned is resisted by means of friction pads positioned between the dial and the housing.  The indicator motor is secured by a motor housing integrally molded in the housing base and a polyurethane pad cushions the motor.  The motor housing includes side wall members and a cover attached thereto by an integrally molded hinge member on one side wall, and fastening means on the other side walls secures the cover and the motor within the housing.  The housing cover includes integrally molded partial hinge members at one end thereof which cooperate with complementary partial hinge members molded into the base.  Fastening means at the other end of the housing secures the cover to the base thus facilitating assembly.
