摘要:
The present invention is a Miniature Vein Enhancer that includes a Miniature Projection Head. The Miniature Projection Head may be operated in one of three modes, AFM, DBM, and RTM. The Miniature Projection Head of the present invention projects an image of the veins of a patient, which aids the practitioner in pinpointing a vein for an intravenous drip, blood test, and the like. The Miniature projection head may have a cavity for a power source or it may have a power source located in a body portion of the Miniature Vein Enhancer. The Miniature Vein Enhancer may be attached to one of several improved needle protectors, or the Miniature Vein Enhancer may be attached to a body similar to a flashlight for hand held use. The Miniature Vein Enhancer of the present invention may also be attached to a magnifying glass, a flat panel display, and the like.

摘要:
An air conditioning and heating system is disclosed having a manually operated air temperature door that is movable in both an air conditioning mode and a heating mode to regulate the amount of air passing through a heat exchanger to thereby control the temperature of the air delivered by the system. Adapted thereto is an air temperature control arrangement comprising an air baffle that is movable with and adjustable relative to the air temperature control door so as to adjust the amount of air passing through the heat exchanger in the various regulating air temperature door positions. A dual cam track operated air baffle control adjusts the air baffle relative to the air temperature door with movement of the latter and selectively according to one of two predetermined and different cam tracks having linearity patterns determined by the respective air conditioning mode and heating mode heat transfer requirements so as to provide substantial linearity between the temperature of the air delivered by the system and the air temperature control door position in both the air conditioning and heating modes.

A gas turbine engine has a core frame separable from a vane frame for removably attaching the vane frame to a core structure through a mid ring. The mid ring includes an annular forward panel and an annular aft panel, each of which has a radially outer flange and a radially inner flange. The inner flanges are welded to the core frame and the outer flanges are bolted to the vane frame. A plurality of circumferentially spaced stiffeners extend between the forward and aft panels, with each of the stiffeners including a pair of stringers extending diagonally across the stiffeners. Panels may be incorporated with the stringers between the triangular shaped areas adjacent the forward and aft panels of the stiffener. The bolted connection between the mid ring and the vane frame includes a plurality of tongue and groove joints formed in the flanges of the mid ring and vane frame. The tongue and groove joints provide additional radial support for the core engine within the vane frame. Preferably, the tongue and groove joints are formed with angular sides so that conformance between the joints can be achieved by simply tightening the bolts attaching the joints. In one embodiment, the tongue and groove joints may only be used at preselected circumferential positions with the remainder of the flange connections using overlapping lap joints.

A shrouded blade for insertion into an axial disk slot and having a radial spacer and a circumferential groove is provided with a segmented retainer bar which fits into the circumferential groove to axially retain the blade. The retainer bar includes flanges which extend radially inward on either side of the spacer such that the spacer provides positive placement for the retainer bar in both the radial and circumferential directions.

A keyless locking system for a cart includes a lock mechanism with a drive mechanism in the form of a solenoid that is electrically coupled to an integrated circuit and a long lasting power supply. In an unenergized state, an armature of the solenoid prevents operation of the lock mechanism to release drawers supported by the cart. Upon entry of a correct access code via a keypad associated with the integrated circuit, current is supplied to the solenoid to permit operation of the lock mechanism and thereby release the drawers. Advantageously, the lock mechanism only draws from the power supply to temporarily release the solenoid only thereby requiring minimal power and significantly reducing the re-charging, replacement and maintenance requirements for the power supply and the down time for the cart.
摘要:
An assembly for mounting a plurality of circumferentially spaced and radially extending airfoils. In a preferred embodiment the assembly comprises a plurality of arcuate mounting fairings each including a central boss having at least one radially extending recess disposed in a radially inner surface thereof which contains an elastomeric boot for receiving an end of one of the plurality of airfoils. The mounting fairing further includes integral first and second flanges extending circumferentially outwardly from opposite sides of the boss portion which overlap complementary second and first flanges, respectively, of adjacent mounting fairings. Fastening means connect the first and second flanges of adjacent mounting fairings to form a continuous annular shroud.
