Abstract: A key security device includes a rigid housing with an internal latching device to releasably secure a key within an open keyway formed in the housing. Circuitry is provided along with the latching device to supply an audible or otherwise detectable signal that is initiated following removal of the key and passage of a predetermined timed interval following removal of the key from the housing. Circuitry within the housing responds to insertion and removal of the key to produce an indentifiable alert signal after a determined time interval that may be initiated in response to removal of the key from the keyway. The time interval is reset and the alert signal is cancelled as the key is received in the keyway. An override is provided for the timer and may be operated to selectively extend the time interval and thereby delay operation of the alarm.

Abstract: A method is disclosed for forming a capacitor on a semiconductor wafer which utilizes top and back sides of a capacitor node for capacitance maximization. First and second dielectric layers, having different etch rates, are applied atop the wafer, and a contact opening is etched therethrough. Poly is applied and etched to begin formation of one node of the capacitor. A layer of oxide is then formed atop the poly capacitor node. The first dielectric layer is then etched, leaving a projecting or floating capacitor node which is surrounded by the second dielectric material and oxide formed thereatop. The surrounding material is then etched, the capacitor dielectric applied, and the poly of the second capacitor nod applied and selectively etched.

Abstract: Disclosed is a radiation dosimeter reading apparatus designed to disassemble, reposition, read, and reasemble radiation dosimeter badges. The dosimeter reading apparatus includes a dosimeter badge chuck assembly which engages a dosimeter badge in an infeed dosimeter badge holder. The chuck assembly engages the dosimeter badge using a set of tamper element prongs which depress a tamper ring which forms part of the dosimeter badge. The depression of the badge tamper ring releases a locking ring which also forms part of the dosimeter badge. Once the locking ring is freed, then another set of prongs on the chuck assembly are rotated to route the locking ring of the badge and thereby release a disk-shaped dosimeter badge insert. The chuck assembly is further adapted to grasp the released insert by contracting the tamper element prongs inwardly against the perphery of the disk-shaped insert to hold the inset on the chuck assembly.

Abstract: An apparatus is described for producing concave or convex optically magnified facets about a gem, each facet being a curved surface that is a section of a cylinder. It utilizes a mandrel having an exterior and/or interior cylindrical abrasive surface. The surface is contacted by a gem indexed and adjustably held by a gem support structure. The mandrel is angularly movable about its central axis. It can also be reciprocated along the axis to prevent formation of random striations across the facet surfaces. An adjustable stabilizer can be preset to engage a dop attached to a gem at a location adjacent to the mandrel. This assures accurate reengagement of the gem after movement from the mandrel for interium inspections during the faceting precedure. The method of producing the optically magnified facets requires successive indexing of the gem and bringing it into contact with an angularly moving cylindrical abrasive surface.

Abstract: Successive blocks of corrugated sheets are divided from a large vertical stack by a combination of a horizontally movable pusher plate and a guiding ramp that lifts the front edge of each block of sheets upwardly and onto a receiving conveyor surface. The ramp is a hybrid that includes a powered cylindrical roller and an adjacent yieldably biased upright plate that is moved to an inclined position in response to initial movement of a block of sheets.

Abstract: Disclosed is a laser dosimeter reading apparatus having a controllable optical laser converter for providing multiple stimulating laser beams. The convertible laser dosimeter reader can be used to stimulate or otherwise treat dosimeter elements to perform two or more distinct processes on a particular dosimeter element. Additionally, the convertible dosimeter reader can be used to read multiple different types of dosimeter elements contained on a single dosimeter badge, thereby allowing a badge to be read in a multi-stage reading operation in a single dosimeter reader which is preferably automated. The optical laser converter includes a converter block assembly which defines multiple optical pathways therethrough. The convert block assembly is movable between different positions to align the different optical pathways with an incoming laser beam.

Abstract: A squaring and aligning assembly for the transfer frame of a corrugated sheet stacking and feeding apparatus is mounted within a transverse guide member in the form of an elongated channel. Separate squaring shoes at each side of the machine are selectively moved along the channel. They can be connected in centered positions along opposite flights of a powered chain to center a block of sheets relative to the machine. One can be connected to a chain flight in an off-center position to align the block of sheets in an off-centered aligned condition. Either shoe can be clamped to the channel for edge alignment in response to movement of the remaining shoe.

Abstract: A two-step orthodontic process is described in which a first weave 35 and a subsequent second weave 40 of fine dental floss are applied to a selected group of tooth crowns to effect correction of maloccluded teeth in the group. In the first weave a strand 10 of dental floss is placed in a figure "8" pattern about crowns 16 in the group. The strand 10 of material is secured in a knotless configuration by wedging the material of the strand 10 against the contact points 30 between adjacent teeth. The figure "8" pattern serves to span lingual 25 and facial surfaces 24 of the crowns in the group and to exert corrective forces against the teeth, causing them to move into prescribed desired alignment. In the second weave 40, a strand is applied with at least one span 41 of the strand across facial surfaces of the crowns 16 within the group. The span 41 is used to exert forces tending to gather and contour the crowns in a finishing technique.

Abstract: A vibratory conveying and separating apparatus and a clamping device therefor are disclosed. The apparatus includes a conveyor bed which supports processing screens which convey and separate material being processed. The bed is vibrated in a forward and upward direction at a predetermined forward and upward angle of inclination. At least one releasable clamping device engages between the conveyor bed and processing screen to provide a releasable clamping force against the screen for clamping it to the conveyor bed. The clamp is mounted or positioned to orient the releasable clamping force substantially parallel with the predetermined forward and upward angle of inclination.

Abstract: A method of coating a substrate comprises plasma spraying a prealloyed feed powder onto a substrate, where the prealloyed feed powder comprises a significant amount of an alloy of stainless steel and at least one refractory element selected from the group consisting of titanium, zirconium, hafnium, niobium, tantalum, molybdenum, and tungsten. The plasma spraying of such a feed powder is conducted in an oxygen containing atmosphere and forms an adherent, corrosion resistant, and substantially homogenous metallic refractory alloy coating on the substrate.

Abstract: A method for improving step coverage of metallization layers of an aluminum alloy on an integrated circuit involves use of a deposited layer of a high melting point metal, such as tungsten or an alloy of tungsten and titanium, as an anti-reflective coating (ARC) to increase the efficient use of laser energy for planarization purposes where the underlying aluminum alloy covers a step, such as at an open via.

Abstract: A seedling planter utilizes support wheels located on a main frame near the rear of the planter. The support wheels are pivotable relative to the frame, thereby allowing the force exerted by a set of intermediate packing wheels to be varied. The seedling planter was a novel planting assembly which incorporates two primary structural members; a first planting assembly piece or link which is connected to the frame, and a planting arm which is pivotally connected to the first piece. The first piece is movable to vary the height of the pivot axis about which the planting arm rotates. The planting assembly also includes a soil height level detection subsystem to automatically control downward extension of the first planting assembly piece. The planting arm is thus positioned at a desired predetermined height above the soil as it is rotated into the ground to provide consistent planting depth. A cam-operated seedling holder clamps the seedlings along the rear edge of the planting arm.
