Abstract: The present invention relates to an improved leadframe and method of attaching leads of a leadframe to contract pads on a carrier. The leadframe includes resilient engaging means or fingers for engaging the carrier and for exerting forces on the carrier to thereby support the carrier and accurately position and align the contact pads on the carrier with the leads. This invention overcomes the expense and inaccuracies of known leadframe designs and techniques in attaching leads to carrier contact pads using such things as fixtures for positioning the leadframe and carrier, visual alignment procedures and retaining tabs.

Title: Chromate-free protective coatings
Inventor: TAYLOR RAY S
IPC: C23C22/56
Filed: 1997-02-26
Granted: 2003-10-21
Abstract: The invention provides chromate-free coating mixtures, and coatings formed from these mixtures, that protect an underlying aluminum or aluminum alloy substrate from corrosion. The coating mixtures include a continuous phase selected from organic polymeric compositions, or sol-gels, and a distributed phase, dispersed or dissolved throughout the continuous phase. The distributed phase includes the corrosion-inhibiting chromate-free salts. In accordance with the invention, the mixture of salts includes (1) a first salt selected from (a) the esters of rare earth metals, such as cerium and lanthanum oxalates and acetates, and (b) the vanadate salts of alkali and alkali earth metals, such as sodium metavanadate and calcium metavanadate; and (2) a second salt that is a borate salt of alkali earth metals, such as barium metaborate. In certain embodiments, the coatings of the invention includeboth (a), and (b), in conjunction with the borate salt (2). In other embodiments, the chromate free salt is a chloride of a rare earth metal, or mixture of such chlorides, either alone or in combination with the first salt or the second salt, or both the first and second salts. Coatings of the invention provide protection to an underlying substrate, even after subjection to a 3000 hour salt spray test. Moreover, the coatings are resistant to degradation by SKYDROL, and are able to withstand impacts of 50inch-pounds (forward) and 30 inch-pounds (reverse), so that they are well suited for use as protective coatings for aircraft.

Filed: 1996-09-16
Granted: 2007-02-06
Abstract: The invention relates to a method and an apparatus for providing a given volume of a test substance (H2) in a monitoring line (2) which is filled with a test medium (e. g. air) and is provided along a section for determining concentration profiles. For the purpose of transporting a column of test medium through the monitoring line (2), the pressure (p) in the monitoring line (2) is increased by switching on a pressure pump or, for the same purpose - in an alternative embodiment - is reduced by switching on a suction pump (12). A given metering volume of the test substance (H2) is automatically released in the monitoring line (2) when a given limit for the pressure (p) is passed. The release of the given metering volume of the test substance (H2), after it has been carried along by the column of test medium, results in a test peak in a sensor (11) which responds to the test substance (H2) and is connected to the monitoring line (2).

Abstract: An apparatus (10) is provided for detecting deformation in solids in deep holes having a resilient vessel (12) pre-stressed into a rock formation. The vessel (12) is filled with fluid (14) and is sealed except for an outlet tube (16) of small diameter which extends all the way to, or close to, the surface (18). There the outlet tube (16) terminates in an extensible bellows (20). The whole apparatus is completely filled with fluid (14). Any deformation of the vessel (12) will cause fluid to be forced through the outlet tube (16) and so cause the bellows (20) to extend or contract. This motion can be monitored by any position-sensitive transducer (22) such as a linear variable differential transformer or capacitance bridge. A second tube (24) of the same length and size as the outlet tube (16) is filled with the same fluid. This tube (24) terminates at the bottom in close proximity to the resilient vessel (12). It also has a bellows (26) and a displacement transducer (28) at its upper end at the surface (18).

Abstract: A cable assembly secured inside the trunk compartment of a motor vehicle having dual actuator cables. The cable assembly includes a housing, a pulley member rotatably mounted to the housing and a slide lock member. A first actuator cable slidingly cooperates through the housing and pulley member with one end attached to a pull-strap inside the trunk compartment and the second end attached to a release latch. A second actuator cable has one end attached to a pull-strap located in the proximity of the driver's seat and the second end attached to the pulley member to rotate the pulley member upon pulling the pull-strap. Rotating the pulley member allows the pulley member to engage a ball slug on the first actuator cable to drive the second end and actuate the release latch. A slide lock member is capable of engaging the pulley member to prevent rotation, and therefore, prevent the pull strap in the passenger compartment from actuating the release latch.

Abstract: A 1xn optical deflection switch has an array of k transmissive light deflectors to switch an incident light beam into one of n=2 k directions. The switch can steer the light through the deflectors into one of a plurality of beam directions, by selectively individually inserting them into the light path. One embodiment uses four glass rectangular blocks as light deflectors having parallel upper and lower surfaces oriented at a predetermined oblique angle to the incident light beam. The thicknesses of the blocks follow an increasing order in proportion to successive powers of 2, i.e. t, 2t, 4t and 8t, giving a total of 16 switching positions. Another embodiment uses two arrays of 4-block switches, and selectively activates blocks from either array to provide a 1x32 switch. Yet, another embodiment uses four stepped deflectors each having two selectable sections of dissimilar thicknesses to give a total of 15 switching positions.

Abstract: An automated conveyor sortation and item discharge system (10) for sorting items (24) of varying sizes and weights to designated output destinations (16) along a conveyor (10). The system (10) utilizes a segmented slat (18) conveyor connected by flexible connectors (36). The flexible connectors (36) form a tooth (40) for driving the conveyor (10) by a sprocket (58). The flexible connectors (36) isolate adjacent slats, and the flexible teeth (40) isolate the slat (18) conveyor from the drive sprocket (58) for an enhanced reduction in noise levels. The system (10) may utilize a conventional belt (225) conveyor or rigid platforms (18) attached by flexible connectors (36). Removable ejection mechanisms (124) can be attached to the individual slats (18) of the slat conveyor (10) or to the belt of a belt conveyor (225). The ejection mechanisms (124) have self-contained drive (154) and actuation mechanisms (148) and may operate independently of the speed of the conveyor (10). The drive mechanism (300) for the ejection mechanism (220) may be located separately from the ejection mechanism (220) to drive the ejection mechanism (220) when the ejection mechanism (220) moves adjacent to a desired discharge destination (16). A programmable controller may be provided to control the conveyor (10) and the discharge of items (24) from the conveyor (10) by the ejection mechanisms (124, 220). The system is easy to repair and operates at high speeds at reduced noise levels.
