Abstract: ABSTRACT OF THE DISCLOSURE            A method for removing resilient gallery lining frames in mining and tunnelling, such frames consisting of a number of mutually overlapping lining section segments with a box-like profile, comprises releasing the overlapping section segments from one another in order to recover the respective lining frames.  The profile of the section segments has a longitudinal gap and over-lapping ends of the segments are braced one with another by a wedge system acting on the longitudinal gap of the inner section, the segments being inserted one within the other in a dissimilar manner.  At an overlapping region the outer section segment is bent outwardly to provide an opening at the longitudinal gap therein and the inserted end of the inner section segment at the overlap is moved substantially normal to the opening made by the outward bending to release the overlapping sections from one another.

Abstract: TIMEPIECE CALENDAR INDEXING APPARATUS                  ABSTRACT OF THE DISCLOSURE An indexing apparatus for changing automatically and rapidly calendar information of a clock includes an indexing assembly having both day and date means, each engageable with for driving respective day and date discs provided with calendar indicia.  A cam driven by the drive train of the clock mechanism rotates through a full revolution each 12-hour period.  A member including a plurality of gear teeth arranged in a sector is mounted for pivotal movement against the bias of a spring which positions the member in the path of movement of the cam.  The indexing assembly, further, includes an element formed by a disc and a sector gear which is driven in opposite directions by the member whose gear teeth are in driving engagement therewith.  The disc of the element includes a pair of substantially diametrically oppositely disposed notches having oppositely inclined ramps between the upper and lower surfaces of the clutch disc. The components of the indexing assembly are mounted in a stack with the day means between the date means and the element.  The day means includes a pair of follower projections which normally are disposed within the notches; the day means being movable with the element in one direction to index the day disc through a partial revolution yet will idle upon movement of the element in the other direction whereby the teeth ride out of the notches along the ramps.  Means are provided to prevent movement of the day and date means during idling.  The day disc includes a plurality of projections which sequentially engage the date means so that upon each second index of the day means the date disc undergoes an indexing movement in the one direction.     The calendar information, also, may be changed selectively by a clutch arrangement activated by a setting stem, -1a-

Abstract: DETECTION SYSTEM FOR LIGHTNING                  Abstract of the Disclosure A lightning detection system utilizes a gated magnetic direction finder for determining the range and direction of lightning discharges to ground.  Logic circuitry is provided for controlling gating circuits within the direction finder so that the direction measurement is made during the initial few microseconds of the return stroke waveform, thereby minimizing errors caused by nonvertical lightning channels to ground, branches and intracloud dis-charges.  Distance measurements are made by analyzing the amplitude of the detected return stroke waveform, or by uti-lizing two or more geographically separated direction finders and triangulation techniques.  The waveforms of the signals received by the direction finder are analyzed to determine whether the discharge is a ground stroke or another type of discharge, or background noise.  Further circuitry can be used to distinguish between various types of ground strokes, such as first strokes or subsequent strokes in a flash.

Abstract: FLOATING HEAT INSULATING BAFFLE FOR DIRECTIONAL SOLIDIFICATION APPARATUS    UTILIZING LIQUID COOLANT BATH           ABSTRACT OF THE DISCLOSURE  An improved casting apparatus for directionally solidifying molten metal is disclosed.  The apparatus typically includes a furnace for heating a mold con-taining molten metal, a liquid metal coolant bath posi-tioned below the bottom of the furnace and means for gradually withdrawing the heated mold from the furnace into the coolant bath to effect directional solidifica-tion of the molten metal.  The apparatus is improved by positioning a heat insulating baffle between the bottom of the furnace and coolant bath, the baffle being con-structed to float on the bath surface during the solidi-fication process and minimize heat loss from the mold until it is immersed in the bath.  The provision of the floating baffle between the furnace bottom and coolant bath provides several important advantages including increased thermal gradients, shorter casting cycles and improved cast microstructures.  In addition, the floating baffle reduces vaporization of the liquid metal coolant and maintains a smooth, ripple-free coolant surface.     EH-6232b
