Abstract: A device for preserving freshness of contents, such as but not limited to, coffee, paint, nuts, etc., of a container. The device includes a body and a handle. The body is free of venting bores, comes to rest on the contents of the container, and substantially engages the inner side surface of the container, to preserve the freshness of the contents of the container by blocking virtually all air in the container from contact with the contents of the container. The handle extends foldably from the body so as to self-fold onto the body and prevent interference of the handle with the lid of the container when the contents of the container are at such a level in the container that the handle would, in its normal upward position, be interfered with by the lid of the container.

Abstract: A tubular sleeve having an open top, a closed bottom wall, a front and back faces and a pair of opposing side walls connecting the front and back faces. The side walls are formed with at least one gusset allowing the front and back faces to extend from each other. The gussets are sealed unitarily at the bottom ends to form the bottom wall. The “square bottom” bag takes on a triangular lengthwise shape normally biased closed at the top but easily openable for maximum filling and discharge of the interior of the bag.

Abstract: A lighting system has a base and at least one vertical support (trunk) that frictionally engages the base. The vertical support (trunk) has apertures around its circumference and its inner circumference is lined with longitudinal current carrying conductors. A low voltage transformer disposed within the base and electrically connected to a voltage supply contact in the base. The longitudinal current carrying conductors engage the voltage supply contact when the vertical support frictionally engages the base. Pairs of current carrying rods (branches) frictionally engage the vertical support (trunk) at the apertures and have voltage supply contacts that contact the longitudinal current carrying conductors. Ornaments having resilient clasps, with a pair of separately disposed electrical contacts on both sides of the clasp, frictionally engage the current carrying rods (branches) and electrically connect the current carrying rods to the electrical contacts and the ornament.

Abstract: A tubular sleeve is shaped with a pair of opposing faces, a pair of opposing side walls, and a lowermost terminal edge. Double gussets are simultaneously formed on each opposing side walls of the shaped sleeve inward between the pair of opposing faces of the shaped sleeve and defining substantially square corners at intersection of the longitudinal ribs of the shaped sleeve and the lowermost terminal edge of the shaped sleeve. The square corners of the shaped sleeve are relieved and removed to form a flat bottom. A pair of handles are unitarily formed and integral with the frontal faces extending over the open top.

Abstract: A golf green repair tool that includes a housing, a blade, locking apparatus, and extending apparatus. The blade is operatively attached to the housing, and has a retracted/stored position where it is contained within the housing and an extended/operational position where it is extended from the housing. The locking apparatus maintains the blade in each of its retracted/stored position and its extended/operational position by being engaged with the blade and releases the blade from each of its retracted/stored position and its extended/operational position by being disengaged from the blade. The extending apparatus automatically moves the blade from its retracted/stored position to its extended/operational position when the locking apparatus is released.

Abstract: A panel for forming on-site a multi-function channel. The panel is a sheet of material that is rectangular-shaped, slightly compressible, thermally insulating, and has a pair of pre-printed channel flange fold lines that extend the entire length thereof and which form a pair of channel flanges when the sheet of material is folded perpendicularly upwardly thereon, and a trio of pre-printed soffit vent baffle panel fold lines that extend the entire width thereof and have a selected one thereof forming a soffit vent baffle panel when the sheet of material is folded perpendicularly downwardly thereon. When the pair of channel flanges are intimately abutted against a pair of parallel, adjacent, and spaced-apart framing members, the sheet of material compresses enough to provide an outward force sufficient to allow the multi-function channel to be self-restraining between, and by, the pair of parallel, adjacent, and spaced-apart framing members without a need for fasteners.

The improvement further includes two embodiments of apparatus for replaceably attaching the sight pin guard to the base without a need for tools. The first embodiment includes terminal ends of the sight pin guard and ends of the base having cooperating slots. The second embodiment includes the terminal ends of the sight pin guard formed with indents that cooperate with spring clips on the ends of the base.

Abstract: A tilt ramp swept edge nozzle for vectoring exhaust gases from an engine mounted in an aircraft has a pair of flaps pivotally affixed to the aircraft in the area of the output end of the engine tailpipe. The flaps are in spaced relation to each other, aligned with the trailing edge of the airfoil of the aircraft and are movable to positions substantially parallel to each other and to positions substantially non-parallel to each other. An actuating system coupled to the flaps moves same relative to each other thereby to maintain a substantially constant effective throat area in the nozzle and providing an increasing nozzle aspect ratio and variable thrust direction during transition from forward to aft throat position of the nozzle.

Abstract: The invention features an optical spread spectrum decoder wherein linear, non-linear, and discontinuous broadband RF signals can be optically decoded.The system introduces a weighting function into a local oscillator beam, which is then combined with a laser beam which has been modulated with the RF signal, processed to remove unwanted spectral components and then compressed. The combined beams are then down-converted to recover the RF signal.

Abstract: An electronic blanking system having a plurality of inputs from a number of radio frequency transmitters and a plurality of outputs for supplying blanking pulses to receivers which are in proximity to the transmitters includes input circuitry for processing input pulses from the inputs to produce processed input signals. Timers alter the timing of the processed input signals as required to produce the needed blanking pulses. Matrix means are provided for routing each blanking pulse to the outputs. A processor controls each matrix to determine the routing. Output drivers supply the blanking pulses, at predetermined voltage levels, to the outputs. The processor also controls the timers to determine the manner in which the timing is altered. The timers includes at least one of a delay for delaying the processed input signals, a stretching circuit for increasing the length of the processed input signals, and a truncator for truncating the length of the processed input signals.
