Abstract: Tip shrouds or other shrouds with multi-slope geometries are generally implemented using segments, since performing the necessary cut for an alternative split-ring design is difficult given conventional cutting processes. However, a segmented design generally results in more leakage, relative to a split-ring design. Accordingly, a split-ring multi-slope design is disclosed that can be more easily manufactured. In particular, a continuous ring may be cut along a linear path to produce a split ring, and then the ends of the split ring may be machined to form complementary shiplap portions. The split ring may then be compressed for installation by overlapping the shiplap portions, to form a seal against leakage through the shroud.

Abstract: A method of severing an extraction line connected between an extraction parachute and a cargo load when the cargo load fails to eject from an aircraft. The method comprises the steps of spacing a cutter from the extraction line; spring-biasing the cutter in the direction of the extraction line; mechanically restricting the cutter with restricting means from engaging and severing the extraction line; and disabling the restricting means in response to a radio signal from a transmitter on the aircraft so that the cutter is released and severs the extraction line.

Abstract: A dynamic probe system for probing a FPGA with at least one core. A trace core is added to the FPGA, the trace core in communication with a plurality of signal banks, each signal bank comprising a plurality of signals in the at least one core. A logic analyzer, in communication with the trace core and selecting the bank of signal to be sent from the trace core to the logic analyzer.

Abstract: A device for severing an extraction line connected between a cargo load and an extraction parachute when the cargo load fails to eject from an aircraft. The device comprises a cutter spaced from and spring-biased in the direction of the extraction line; a housing for the cutter; elements for mechanically restricting the cutter from engaging and severing the extraction line; and elements responsive to a radio signal from a transmitter on the aircraft for disabling the restricting means so that the cutter is released and severs the extraction line.

Abstract: A skid plate for mounting on the end of a boat trailer and bunk includes a lip which depends from the main body of the plate for abutment with the rearward end of the bunk to protect the bunk and the hull of the boat being loaded onto or off of the trailer. The skid plates include an inclined forward portion to facilitate boat hull passage over the plate.

Abstract: A microwave cookware comprising a body and a browning portion having a cooking surface and a separate heat absorbing body. The heat absorbing body is in contact with a heating matrix which absorbs microwave energy such that increased amount of heat is retained for transfer to the cooking surface.

Abstract: A slideable control is provided for use in retractable bristle brushes. It operates by co-action with a rotatable, cylindrical mandrel carrying pivoted bristles and having an angular cam slot. The control includes a longitudinally slideable button in the handle which has a control pin operatively extending through a control slot in the handle and then into the cam slot to cause rotation of the mandrel. The angular cam slot includes an axial portion at each end to receive the control pin and to lock the mandrel in a position with the bristles either fully retracted or fully extended. The control button includes a pair of parallel guide blades, one on each side of the control pin, slideable within slotted guides in the handle, to reduce torque between the control pin and the cam slot. The control slot may include detents proximate to its ends to receive and hold the control pin against longitudinal movement.

Abstract: A hair brush is provided with flock on the outer tubular surface of the brushing portion. The flock is applied directly to the outer surface or mounted on a ribbon which is adhesively applied or mechanically secured to the outer surface. The bristles may also be flocked.

Abstract: Collapsible traffic barricade is described, having a reflective panel mounted on a pair of leg supports which have vertical portions to receive the reflective panel but are angled outwardly so as to provide greater lateral stability. The supports may also be provided with additional mountings capable of receiving additional reflective panels.

Abstract: Aquarium filtration apparatus having a generally trough-shaped filter housing, the rear wall having a bracket portion for hanging on an aquarium, an impeller assembly having a drive magnet being positioned within the bottom of the filter housing with a motor assembly coupled to the undersurface of the bottom with a power driven magnet on the motor assembly in spaced proximate relation to effect magnetic coupling with the magnet of the impeller assembly. An intake assembly is provided in fluid communication with the impeller assembly and with the aquarium water for drawing water from the aquarium into the filter housing. In a first embodiment, the intake assembly is an intake tube having a portion within the filter housing. In a second embodiment, the intake assembly includes a filter chamber within the filter housing in fluid communication with the impeller assembly with an intake tube coupled to the filter chamber for drawing water from the aquarium into the chamber.

Abstract: A dispenser for small animal food or the like, the dispenser including a base member having a planar surface and upwardly extending wall portion defining an elongate trough for tiltably receiving a plurality of unitary hopper members, each hopper member having a front wall, sidewalls, a back wall and a bottom with a pivot projection downwardly depending from the bottom, the pivot projection being generally coextensive or co-planar with the front wall. A depressor pedal member is generally co-planar with the bottom and is supported in generally parallel relation with the planar surface of the base with the hopper member supported within the trough. A cover is provided to completely enclose the plurality of hopper members, the cover having an aperture through which the depressor member extends, the cover aperture being in alignment with a hopper aperture formed in the front wall.
