Abstract: ABSTRACT       IMPROVEMENTS RELATING TO PRINTING MEMBERS  A print member has a print surface of an epoxy novolac resin.  It is particularly suitable for use as an intaglio print member that is to be laser engraved.    It is best made by powder coating a powdered epoxy novolac composition onto the substrate fusing and curing it, polishing it to give non-print characteris-tics and then further curing it, either before or after engraving.

Abstract: ABSTRACT       A canopy kiln system is provided in the form of a flat-topped tent of flexible material (lightweight canvas, etc.) having depending wall to form, when in use, an enclosure for housing one or more articles to be treated or cured, one example being in the curing of cast concrete pipe.  One end of the roof of the tent is attached to a wall or the like and is stretched transverse stiffener, referred to as a strongback.  The strongback is detachably connected to support structure remote from the wall and the sides or curtains of the canopy form walls.  The folding mechanism comprises an overhead hoist that picks up the strong-back and moves it -- and the course the canopy -- toward the wall. During this movement, intermediate lift mechanism picks up an transferred to a cradle which carries the canopy completely to the wall in its folded position.

Abstract: Process for Selectively Depositing a Nickel-Boron Coating Over a Metallurgy Pattern on a Dielectric Substrate and Products Produced Thereby Abstract A process for simultaneously selectively depositing a high purity nickel containing alloy (i.e. a nickel-boron alloy having a nickel content in excess of 93.5 percent) over a preformed metallurgy pattern (including the individual, electrically isolated con-tact pads and the seal band area thereon) on the top-side dielectric surface of a multi-layer ceramic module. The metallurgy pattern on such top-side surface of such module is appropriately catalyzed and then immersed in a bath which is essentially lead-free and which includes a source of nickel ions, a borane reducing agent, and an effective amount of an organic divalent sulfur compound, preferably thiodiglycollic acid.  The contact pads and the seal band area so plated exhibit an exceptionally uniform layer of nickel-boron alloy, free of surface irregularities, which layer is char-acterized by low contact resistance, excellent wire bonding and eutectic diode bonding characteristics and is both crack-free at the time of its being deposited and remains crack-free under brazing conditions through-out the life of the component.

Title: Telescoping tower for floodlighting equipment and the   like
Inventor: ZIEGLER THEODORE J
IPC: E04H12/08
Filed: 1983-12-30
Granted: 1986-08-26
Abstract: ABSTRACT OF THE DISCLOSURE           A telescoping mast assembly for floodlighting equipment or other apparatus is arranged to be raised by admitting pressurized fluid to the interior of the assembly and lowered by releasing the fluid.  The assembly is constructed of light metal, such as aluminum alloy, and includes a plurality of telescoping hollow members, or tubes, each inner member having a pair of substantially spaced wear rings near its lower end for maintaining the spaced positions of the members and a fitting at its outer end carrying an internally mounted wear ring for maintaining the spacing at the outer end.  The telescoping members do not engage one another but are spaced by the wear rings.          The fitting is readily detachable and facilitates the use of straight lengths of standard aluminum tube stock for the mast sections.  The fittings include keys slidably engaging longitudinal slots in the members for preventing rotation of the members with respect to one another.  Seals are provided for preventing leakage of fluid between the members.  The wear ring of the pair remote from the lower end engages the wear ring in the fitting when the members are fully raised, the wear rings acting as stops at the outer end of the movement of the members.  The wear rings cooperate to provide a low friction, smoothly acting mast assembly which may be easily and quickly raised and lowered and which operates smoothly and effectively without metal-to-metal contact and the likelihood of galling of the aluminum or other light metal of the telescoping sections of the mast.

Abstract: ABSTRACT OF THE DISCLOSURE    A signaling device for firing signaling cartridges in an emergency.  The signaling cartridges are adapted to emit light, noise and or smoke signals.  The device includes a grip which manually grasped and which includes a firing lever adapted to be pressed inwardly. The firing lever when in a normal inoperative position forms part of the grip contour . When the firing lever is pressed inwardly it lifts off a rotatably mounted hammer from a firing pin.  The hammer then snaps back via the force exerted by a spring to actuate the firing pin.  Simultaneously with actuation of the hammer the firing lever also effects a rotational advance cartridge magazine of the signaling device.          Alternately, the cartridge magazine can be rotationally advanced with the thumb of the user of the device.  When the signaling device is held its "natural" position it is vertically upwardly oriented so that signaling cartridges are fired in that direction.

Abstract: ABSTRACT OF THE DISCLOSURE     A conveyor chain moves along the periphery of a table.  A number of balloon-carrying members are fixed in spaced-apart relationship to the conveyor chain.  Each member carries a nipple for engaging the neck of a balloon and a balloon-positioning member movable with respect to the balloon-carrying member between a retracted position and an extended operative position surrounding the neck of the inflated balloon and maintaining the inflated balloon in steady position to be printed by a silk-screen printing press.  The balloon-carrying members move in a close path,step by step, through successive stations as follows: stations where deflated balloons can be attached to a nipple; stations where the balloons are inflated; a station where the balloon-positioning member is pushed outwardly to its operative position; a station where the balloon is printed by a silk-screen press; several stations where the ink on the balloon is dried; a station where the positioning member is retracted; and a final station where the inflated balloon is detached from the nipple.

Abstract: ABSTRACT     A   detector   comprising   an   elongated   strip   of semiconductor  material  which  is  photoconductive  by  the generation of electron and hole photocarriers when an image is moved along the strip.   The strip includes an active region and a  readout  region.   A first  bias  current  is applied  through  the active  region  of  the  strip  thereby producing an ambipolar drift of photocarriers in the strip whose velocity substantially matches the velocity of the movement of  the image along said strip. A second bias current is applied to the readout region of the strip so that the drift of the photocarriers in the readout region has a velocity which is greater than the velocity of the drift of  the photocarriers  in  the active  region of  the strip, thereby decreasing the time for readout.
