Abstract: METHOD AND APPARATUS FOR ELECTRIC ARC AND        ANALOGOUS WELDING UNDER PRECISION CONTROL          Abstract of the Disclosure:         Signals which contain components that vary with the lateral position of an electric welding instrument as it travels along a weld path between opposite work pieces are obtained from the arc or other heat source and are first processed to remove con-fusing  or nonsignificant components.  The processed signals are then compared or combined with each other, or with other signals of predetermined value, to obtain outputs which can be used to determine or control the lateral position or movement of the weld-ing instrument along the weld path.  Specifically, in electric arc welding of metals, signals from an electrical characteristic at the arc, such as arc current, which include a component indicative of lateral position of the welding instrument with respect to one or more sidewalls, are first filtered and processed to remove undesir-able components.  Under control of separate timing signals, the processed signals so obtained are sampled to derive and hold peak values indicative of extreme lateral positions of the instrument as it moves from side to side of its main travel path.  By using deliberately timed control signals, these peak values are compared with each other, and/or combined or compared with other signals of known value, to obtain as output the desired position-control signals.  The latter are used to indicate, control and/or to change an extreme lateral position of the instrument either by correcting its centerline of main travel and/or by modifying the width or amplitude of its lateral reciprocation.

Abstract: ABSTRACT      The invention relates to a device for correcting the posture of a human foot.  Unlike custom-made devices, which are made by a specialist to conform to the patient's foot, the device of the invention may be mass-produced and sold in standard sizes.  The device is adapted for placement upon or within a foot-supporting insole structure and comprises an elongated substantially rectangular pad having a first area of substantially uniform thickness and a second area of a relatively greater thickness.  A rearward end region of the pad is part of said first area of substantially uniform thickness and is adapted to support a medial inner one third of the calcaneous bone of the foot.  A forward end region containing said second area of re-latively greater thickness is adapted to support the surgical neck region of the first metatarsal bone of the foot.  The thickness of said first area is such that the calcaneous bone is tilted at an angle of between 2 1/2° and 8 1/4° with respect to the major plane of the insole structure and the forward region of the foot containing the surgical neck regions of the metatarsal bones is tilted through an additional 1 1/2° to 6 1/2°.  Preferably, the thickness of said first area is sufficient to tilt the calcaneous bone through an angle of 4 1/2° and the thickness of said second area is sufficient to tilt the forward region of the foot through an additional 2 1/2°.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved pressure compensator for earth boring drill bits for minimizing the pressure differential between the lubricant and the well bore.  A flexible diaphragm is located in the lubricant reservoir for separating the lubricant from the borehole fluid.  The diaphragm is positioned in the reservoir so that a substantial void space exists on the borehole fluid side of the reservoir.  A retainer holds the diaphragm in this position, requiring a positive lubricant pressure to stretch the diaphragm in order to fill the void space.  For lubricating the bit, the lubricant is introduced under pressure sufficient to stretch the diaphragm.  The lubricant pressure is then released, allowing the compensator to return to its original shape which in turn causes the excess lubricant to be expelled.  This assures complete filling and a desired void space.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure is directed to improvements in piercing and reeling mills, to facilitate the changing of mandrel plugs and mill shoes.  In piercing and reeling operations, mandrel plugs are supported at the ends of elongated mandrel bars, and work-pieces are driven over the mandrel plugs while being rotated,  o effect piercing and enlarging, in the case of piercing mills, and to achieve roundness, in the case of reeling mills.  In each case, after processing a finite length of tubing, and while the work-piece remains on the mandrel, the mandrel is retracted, first stripping off the just-used mandrel plug, and then withdrawing the mandrel from the processed workpiece.  A multi-position magazine is provided for retaining a circulating supply of mandrel plugs such that, after each operation, the used mandrel plug may be returned to the magazine for cooling, and a new plug may be brought quickly into working position ready for the next operation.  The arrangement of the invention provides for expedited loading and discharge of the mandrel plugs, for greater efficiency in mill operation.          The invention is further directed to improvements in mechanisms for changing of mill shoes and mill shoe adapters, as is necessary from time to time in conjunction with changing of the size of the workpiece processed.  The improved arrangement permits an upper mill shoe to be released and supported on the lower mill shoe, and includes provisions for horizontal transfer of the lower shoe, along with the released upper shoe, to a position clear of the mill rolls, where they are easily accessible to an overhead mill hoist.  Provision additionally is made to facilitate and expedite the removal from the top of the mill of the entire mounting chair for the upper mill shoe and its adapter, to facilitate change of the adapter and chair for different sizes of workpieces.

Abstract: DETECTOR CIRCUIT               ABSTRACT OF THE DISCLOSURE         Disclosed are apparatus and methods for detecting the presence, or absence, of material at a predetermined location.          An oscillator generates a constant-frequency, constant-amplitude signal which is fed through a load resistor to an antenna probe positioned at the sensing location.  The amplitude of the signal fed to the antenna probe varies as the impedance of the antenna probe is affected by material in its environment, or lack thereof.          The signal amplitude is converted into a d-c voltage level, and is transmitted to a switching circuit which provides an output signal depending on a comparison between the d-c voltage level and a reference voltage level.  The sensitivity of the switching circuit is adjustable to accommodate the degree to which the particular material, whose presence or absence is to be detected, affects the impedance of the antenna probe.  In a method of the invention, a constant-amplitude signal is fed to an impedance bridge which includes an antenna probe whose impedance is affected by its environment.  The resulting amplitude-modulated signal is used to generate a d-c voltage level reflecting the impedance changes.  The voltage level is used to control a switching circuit.          The switching circuit is provided with a sensitivity adjustment whereby the sensitivity of the switching circuit response is varied to reflect the degree of impedance change that may be effected by the particular change in environment, of the antenna probe, to be detected.  The output from the switching circuit may be used to operate one or more devices indicative of the environment of the antenna probe and/or affecting the environment by adding to and/or removing therefrom material affecting the impedance of the antenna probe.

Abstract: ABSTRACT OF THE DISCLOSURE           A compact electrochemical gas sensing cell is described for detecting gases which are either immediately dangerous to health such as carbon monoxide, N02, etc., or represent a social or public welfare risk.  The latter area, for example, may require determining alcohol breath content of a driver of a motor vehicle.  The cell uses a hydrated, solid polymer electrolyte which has sensing and reference electrodes positioned on one side of the solid polymer electrolyte membrane and a counter electrode positioned on the other side. One side of the hydrated SPE membrane is flooded with distilled water so that incoming gases are brought to essentially 100% relative humidity by rapid vapor phase water transport across the membrane, thereby eliminating the need for external humidification in the form of bubblers and the like.  An ionically conductive hydrated SPE bridge is formed on one side of the membrane and is located spatially to provide a low resistance path between the reference and sensing electrodes.

Abstract: ABSTRACT     Accelerating and Decelerating Handrail A handrail having accelerating and decelerating regions whereat people board and alight from an accelerating and decelerating walkway is disclosed.  The handrail com-prises a plurality of overlapping handrail elements.     The elements move in a vertical, oval track having lengthy sides joined by curved ends.  Acceleration of the handrail is synchronized with the acceleration of the moving walkway, and occurs immediately subsequent to the entry of people on the moving walkway.  Deceleration of the handrail is synchronized with the deceleration of the moving walkway, and occurs just prior to the exit of people from the moving walkway.  Pairs of adjacent over-lapping handrail elements are operably connected together by an extendable and retractable member.  Each extendable and retractable member is also connected to a cam follow-er.  The cam followers follow acceleration and decelera-tion cams located internal to the vertical, oval track that defines the handrail path of travel.  Through the extendable and retractable member, cam action causes the amount of handrail element overlap to increase or decrease to create deceleration or acceleration, respectively.
