Abstract: ABSTRACT OF THE DISCLOSURE         In the system disclosed a driving circuit repeatedly scans along a plurality of aligned electrodes in an enclosure filled with ionizable gas, by sequentially grounding the aligned electrodes and repeating the process cyclically.  Within each cycle, a pulse width modulator energizes an anode opposite the electrodes for a period of time corresponding to an input value.          Sequential glow discharges thus occur between the cathodes and the anode over a portion of the anode length.  The discharges occur with sufficient rapidity so that they are observed as an illuminated portion of a bar formed by the electrodes.  A second set of electrodes is scanned and an opposing anode energized to produce two illuminated bands separated from each other.  Desired upper and lower set point limits for the input quantity determine the lengths of the bands and the separation between them.  Accord-ing to one embodiment, the separate bands are initiated from opposite ends of the bar formed by the electrode alignment with suitable reset cathodes.  The driver forms one band from one end of the aligned electrodes and the other band from the other end of the aligned electrodes.  According to another embodiment the space between the bands is formed by decreasing the anode current only enough to reduce the glow.

Abstract: ABSTRACT     A sheet like structure comprises a metal substrate which is impressed so as to have projections on one side and depressions on the other with an adhesive membrane contiguous to it on one side.  The impressions in the metal allow it to be readily bent and after bending to lie flat rather than become arched.  The metal is preferably aluminium and the invention allows the application therefore of a thin metal sheet, for instance on an outside surface where it will absorb ultraviolet radiation and thus protect the adhesive membrane by which it is secured to the surface to be protected.         The adhesive membrane is preferably bituminous, preferably a bitumen rubber mix.

Abstract: ABSTRACT OF THE DISCLOSURE      Large hole boring equipment is used for boring a large diameter blind pilot hole.  Then such equipment is removed from the hole and a room is blasted at the closed or blind end of the hole.  Then the large hole cutterhead is replaced by a reamer and the equipment is inserted back into the hole.          The reamer is an adjustable diameter type and its diameter is increased once it is within such room.  A wrench carried by the drive head of a drilling machine is used to rotate a small diameter shaft which extends downwardly through the drill string to a lead screw which is a part of the reamer.          Rotation of the lead screw causes axial travel of a lead nut.          As the lead nut travels it moves a plurality of links which in turn swing a plurality of cutter carrying arms outwardly from the axis of rotation.  Once the desired fly diameter of the reamer is achieved  the wrench is removed from the drive head  then the small diameter shaft is locked against additional rotation  and the drive head is drivingly attached to the upper end of the drill string so that it can be used for rotating the drill string and the reamer attached thereto.

Abstract: ABSTRACT OF THE DISCLOSURE    A vertical extending, uniform cross sectional, air impervious chute is open at its opposite ends and shaped to conform to the shape of the articles to be transported from an upper station to a lower station, so that by maintaining an article in the lower end of the chute to seal the lower end of the chute, other articles may be dropped into the chute so that they will pup air ahead of them to build up air pressure between moving articles and down-stream articles.  As a result, falling articles will decrease in acceleration to zero acceleration after they are dropped to a midpoint of their fall as the velocity increases from zero to a maximum, and thereafter the trapped air ahead of them will cause an increasing deceleration and a corresponding decreasing velocity until such falling article gently comes to rest due to the inter-position of a high pressure air cushion onto a down-stream stationary article.  Automatic article sensors may be used to prevent the removal of the last article from the chute so as to maintain the chute seal, particularly when interlocked with a power transfer device, and further sensors may be provided at the entrance of the chute to indicate when the chute is full for the control of an automatic article feeding device.  The chute may be used to transport articles between different levels, or to vertically store articles in a space saving manner for a multiple article picker system.

Abstract: ABSTRACT OF THE DISCLOSURE A continuous motion ribbon imprinter moves with and marks a moving web on a packaging machine and has an easily set control adjusting step-by-step advance of the ribbon across the type block to accommodate wide varia-tions in the size of the printer indicia so as to always present just enough length of fresh ribbon to cover the type for the next imprint.  A frame mounting the type block and ribbon reels swings in either a clockwise or counterclockwise orbital path having a dwell stroke on the moving web, and a lift stroke spacing the ribbon from the web.  The ribbon remains stationary on the type block during the dwell stroke and is advanced across the type block on the lift stroke.  A single input shaft rotatable in clockwise and counterclockwise directions drives the frame through its orbital path and also drives the mechanism for unwinding the fresh ribbon from one reel and winding the spent ribbon on a second reel in one direction only regardless of the drive direction of the input shaft.  The control includes an adjustable cross head with a slide block selectively positioned on both sides of the center to have a single direction drive even when the drive direction of the input shaft is reversed and driving a link which in turn drives a feed roll mechanism through a one way clutch pulling the needed length of ribbon from the unwinding reel during the lift stroke.  The winding reel is driven through a slip mechanism which maintains the ribbon under tension and winds the spent ribbon on the winding reel as it is pulled step-by-step by the feed roll mechanism.
