Abstract: Apparatus for cooling of an electrical element package, comprising in combination structure including a hollow body, defining a cavity containing cooling fluid, the structure defining an opening or passage whereby direct contact of the cooling fluid with the package is established for heat transfer from the package to the fluid contained in the cavity; a mesh located to enhance the heat transfer, and means for circulating the fluid to transfer heat to other heat transfer means acting to remove heat from the fluid.
Abstract: A method of producing a lightweight heat resistant and insulative composite sheet, and containing glass fibers, consisting essentially of homogenized glass fiber and binder materials forming a first layer, binder material extending in a second layer on a surface of the first layer and bonded thereto, woven glass fiber facing cloth extending in a third layer on a surface of the second layer and bonded thereto so that the second layer is sandwiched between the first and third layers, binder material in all layers being cured, to integrate the layers.
Abstract: The air duct leading to a compressor for a gas turbine or the like often has water accumulating on walls and other structures. Water is removed from the compressor air inlet duct by drains connecting to the inside of the duct, including horizontal and vertical walls and the lower wall or floor of the duct. Drains are also provided on hollow structures such as struts, air inlet cone and inlet guide vanes upstream from the compressor. A suction pump or blower lowers pressure in the drain(s) to a pressure less than air pressure in the duct adjacent to the drain outlet for positively sucking water from the drain.
Abstract: In combination, pressurized fluid contained in a storage vessel, in both liquid and vapor regions, a heat exchanger in the vapor region of the vessel, and a first pressure regulator having an inlet side in communication with liquid in the vessel, and having an outlet side in communication with the heat exchanger, whereby if pressure in the vessel rises to the setting of the regulator, it opens and admits liquid from the vessel to the heat exchanger, to vaporize in that exchanger causing vapor in the vessel to condense, and reducing pressure in the vessel.
Abstract: A two part electrical connector is configured for high amperage transmission. It includes: a primary non-electrically conductive body first and second electrically conductive connector pins a secondary non-electrically conductive body third and fourth electrically conductive sleeves.
Abstract: Fishing reel control apparatus, comprising a pulley carried for rotation in opposite directions; a ratchet wheel carried for rotation; a spring wire wrapped about a portion of the pulley and having a projecting end; a pivoted dog connected to the wire end so that endwise displacement of the wire effected by pulley rotation operates to release the dog from the ratchet wheel when the pulley is rotated in one direction, whereby a fishing line spool attached to the ratchet wheel is free to rotate, as the line pays out from the spool; and whereby when the pulley is rotated in opposite direction the wire is displaced to pivot the dog into engagement with the ratchet wheel, and the spool is rotated by the ratchet wheel to wrap the line as the pulley is rotated relative to the wire.
Abstract: Adjustable lifting apparatus, comprising, in combination, a base, multiple cords connected to the base, a mover to be moved along a slide path in response to force exertion by the user's arms or legs, a connection or connections between the mover and one or more of the cords.
Abstract: An arm supporting pillow in sling apparatus, comprising in combination a flexible sling, with a strap to be supported by a user's shoulder area, an insert pillow received in the sling, to be retrievable from the sling, the sling and pillow dimensioned to receive a user's forearm alongside the pillow, in the sling.
Abstract: Adjustable support apparatus between a boot and a snowboard, comprising in combination a lower support plate connectible to a snowboard, an upper plate carried by the lower plate to be rotatable about a main upright axis, the upper plate connectible to a boot, a retainer connected to the support plate and holding the upper plate in position for rotation, about the axis, and an adjustable holder carried by one of the plates to project upwardly relative to the retainer, the holder having different positions of selectable connection to the other of the plates about the axis.
Abstract: An LED display assembly, comprising a grid of electrical conductors; light emitting diodes in association with the grid and in electrical communication with the conductors that provide power for LED operation, the grid operable to receive heat from the diodes during diode operation, and the array configured for passing coolant fluid for transfer of heat to the fluid. LED packages adjustable relative to a mounting grid, are also provided.
Abstract: A positioner to control the position of a finger or thumb of the hand, comprising an elongated, flexible holder configured to extend along the upper side of the user's finger or thumb; a retainer carried by the holder to retain the tip of the user's finger or thumb, the holder adapted to be anchored, remotely from the retainer, endwise thereof; the holder configured to flex, thereby allowing bending of the finger or thumb, producing tensioning of the holder that resists such bending.
Abstract: Liquid collection apparatus usable during surgery, comprising a shallow tray defining a liquid receiving zone that is upwardly exposed for receiving liquid dropping from a surgery area, and a liquid collector in a zone for collecting dropping liquid while allowing a surgeon to tread over a collector, during surgery.

Abstract: Cymbals operation control apparatus, comprising a mechanism including a lever, a hook on the lever, and a handle on the lever to achieve release of the upper disc to drop toward a lower cymbals disc, means including a vertically movable upright rod to support the mechanism, and a releasable device to block pivoting of the lever.
Abstract: A method of providing a mop with surface scrubbing capability, that includes providing a surface scrubbing attachment device, and attaching the device to the mop for scrubbing presentation to the surface.
Abstract: Fishing jig apparatus, comprising a lure body, a hook having a stem, and a flexible strand connecting the stem to the lure body, the stem having a portion terminating at a barb, and a clip on the body to releasably retain said portion, whereby during travel of the line in the water, the lure body grasped by a fish will facilitate hooking of the fish proximate the body and release of the hook to remain connected via the strand to the lure as the fisherman reels in the line connected to said body.
