Abstract: In a water diversion system, in a preferred embodiment, a first fold of a deflector is disposed into a first hanger cavity and a second deflector fold is disposed into a second hanger cavity. The first fold of the deflector cooperates with the first cavity of the hanger to allow a resistance hinge-like action of the deflector. The deflector may be lifted open by compression of a curve of the deflector to remove the second fold of the deflector from the second hanger cavity. Methods are provided in which, in a preferred embodiment, a deflector-forming machine is disposed above a trough-forming machine and the deflector-forming machine is moveable forward and backward relative to the trough-forming machine.

Abstract: Altitude simulation breathing systems create at near sea level, oxygen partial pressure equivalents to a desired “simulated” above ground level altitude by gas mixing and induce low oxygen content (hypoxia) in a subject through the identical physiologic mechanisms as high altitude. At the heart of all prior art is the oxygen sensor; all decisions about gas mixing are based on a direct measurement of oxygen concentration. These sensors respond slowly requiring them to be used with a reservoir; a volume of gas maintained at a given oxygen concentration. The current invention uses flow based technology and eliminates reservoir associated shortcomings. Central to the function of the current invention is the ratiometric addition in real time of nitrogen to inspired room air which is unpressurized, uncontrolled, and inspired normally. In short, we present new technology to this field not based on oxygen concentration that offers significant improvements in safety, reduced mechanical complexity, and size.

Abstract: An improved process for the catalytic partial oxidation of hydrocarbons to produce hydrogen and carbon monoxide is disclosed. The process also utilizes a novel catalyst configuration containing at least two serially aligned layers containing a noble metal or transition metal catalyst supported on a support. Alternatively the process employs only the first layer of a catalytically active metal dispersed on an inert carrier support to partially oxidize hydrocarbons.

Abstract: A shelf extends inwardly to the gutter trough from the front containment wall of a gutter trough to cooperate with a lip of a cavity structure of a hanger to provide structural stability and optional deflector attachment facility in a rain collection and diversion system. The hanger cavity structure has a containment lip a portion of which extends over a portion of the inwardly extending shelf of the front containment wall to allow functional water bearing capacity of the trough and a lengthened back trough wall to accommodate hanger placement and deflector inclination. The hanger can include deflector-mating cavities that open toward each other to allow compression attachment of the deflector. In a preferred embodiment, the deflector may be attached to a formed trough in which hangers are positioned to allow movement of the trough-deflector combination as a unit from the machine-site to the installation location on the structure. Associated installation methods are provided.

Abstract: A method and article for fabricating gold crown tooth restorations by a novel modification of the lost wax process utilizes mold pattern pre-forms each having a generally cylindrically-shaped base made of material such as wax which is capable of having formed therein and retain an accurate impression of a tooth stump. The pre-form base is surmounted by a hollow cap made of a shape-retaining material such as tin, and a plurality of pre-forms are preferably provided, each having a different exterior shape and size which replicates a tooth of a particular type and size. A pre-form having a shape and size suitable for a particular restoration is selected from the plurality of pre-forms, and the base of the pre-form pressed against a tooth stump to form an impression of the stump in the base, thus converting the preform into a restoration casting pattern for casting a restoration. The pattern is then invested into a semi-liquid slurry of mold material, which is allowed to solidify into a mold.

Abstract: This invention provides a phase splitter device that generates in-phase and quadrature outputs that have a phase difference of substantially a phase set value (e.g., 90°) and an amplitude difference of substantially an amplitude set value (e.g., zero). A first feedback loop controls the phase difference between the in-phase and the quadrature outputs while a second feedback loop controls the amplitude difference between the in-phase and quadrature outputs. The phase splitter device controls the amplitude difference and the phase difference between the in-phase and the quadrature outputs by a common mode of control signals and a differential between the control signals, respectively. In this way, the phase splitter device generates in-phasing and quadrature outputs that have a phase difference and an amplitude difference that is substantially equal to the amplitude and phase set values (e.g., zero and 90°) using a single set of control signals.

Abstract: An integrated circuit includes topological features for weakening or otherwise modifying a blowable fuse in order to decrease the current needed to blow the fuse. This allows a decrease in the size of the circuit components which are needed to supply the current for blowing the fuse, in turn allowing compaction of the layout of the circuitry needed to blow the fuse. To this end, topological features are used to deform the shape of or otherwise modify the fuse, in turn increasing the resistance of the fuse or introducing flaws that allow the fuse to blow at a lower current.

Abstract: Blowable fuses on an integrated circuit are programmed in software, responsive to the control of an addressable memory which communicates with the peripheral data bus of a digital processor to allow increased flexibility of the programming operation, and to allow for correction both during the manufacturing process and after packaging of the manufactured integrated circuit. In a preferred embodiment, the fuses are operated (i.e., blown) responsive to transistor switching elements present on the integrated circuit and which are controlled by the addressable memory. The switching elements, and the associated fuses, can be accessed through software in similar fashion to any other peripheral device. The preferred addressable memory includes an instruction register and a data register, which are loaded from and write to the peripheral data bus. Internally, the data register includes an array of registers corresponding to the fuse links with which the system is associated.

One of the improved features is a unitary metal member cut from an economically patterned metal plate. The unitary members, which are themselves free of any weld lines which may crack under the extreme loads exerted on railway cars, are welded to the underside edge of a respective side plate and welded together beneath the center line of the car body.

Abstract: Vibration damping means for a mounting post of a roll-over protection canopy of a heavy vehicle such as a tractor, earth mover, or the like. A hollow square post has slightly concave walls and slides over an upright square mounting stub on the vehicle, to which it is secured by a bolt which impales the post and the stub. A reduced upper end portion of the stub receives a vibration damping member which is in the form of a hollow square. The member has rounded corners which fit snugly in the corners of the post, and the span across opposite faces of the member is less than the internal width of the post so as not to bind in the post.
