Abstract: Dial-type flow-restriction gauges are used for indicating flow-restriction conditions of fluid filters, such as automobile air and fuel filters. Prior versions of these type filters have been more complicated and costly to manufacture than desirable. Accordingly, the present inventors have devised, among other things, an exemplary dial-type flow-restriction gauge that is inexpensive to manufacture and performs reliability and consistently over a wide temperature range. One exemplary gauge includes an external dial that rotates relative a restriction scale in response to a differential pressure. Placement of the dial on the exterior of the gauge eliminates the need to use clear material and allows embedding of the restriction scale into an exterior surface of the gauge.

Abstract: The present inventor devised, among other things, an exemplary pressure switch that includes a low-pressure switch housing portion and a high-pressure fitting portion. The low-pressure switch housing, which is formed of plastic for example, includes an electrical switch that can be turned on or off by moving a first contact between a pair of stationary contacts. The high-pressure fitting portion, which is formed of metal for example, has first and second barbed or threaded connector ends, which respectively engage an opening in the switch housing and a fluid line of an external system. An axial bore extending through the high-pressure fitting contains a piston which extends into the switch housing and is fastened to the first contact of the electrical switch. In operation, the piston travels within the bore in response to positive or negative pressure, moving the first contact toward or away from the stationary contacts to open or close the switch.

The roller track may have left and right side rails and a plurality of rollers that extend therebetween. At least a portion of the rollers are capable of rotating with respect to the side rails. The roller track may be configured for being oriented at an incline so that objects capable of being located on the rollers are oriented at an incline.

Abstract: A vacuum cast or “solid” transformer coil assembly and a method of manufacturing thereof are provided. A solid transformer coil assembly, according to an embodiment of the invention, includes a dielectric substrate, the coil windings provided around the substrate, and an epoxy compound encapsulating the substrate and the coil windings. The substrate is provided with raised “buttons” comprising the same epoxy material as the epoxy compound used for encapsulation. The buttons maintain a specific distance between the coil and the dielectric substrate. The buttons are arranged such that they support the windings and allow the encapsulating epoxy to flow around them flooding the entire mold without entrapping air or creating voids.

Abstract: An apparatus and a method for purifying and heating air using photocatalytic oxidation. The apparatus includes a housing, a heater, and a photocatalytic oxidation unit disposed within the housing. The housing defines a flow path for air to move through the apparatus such that air from the environment is drawn into the apparatus and passes over the photocatalytic oxidation unit. A pollutant in the air from the environment adsorbs to a surface of the photocatalytic material coating the plates, and the surface of the photocatalytic material is exposed to ultraviolet light generated by the ultraviolet light source. The energy of the ultraviolet light activates the photocatalytic material, which then breaks down the pollutant leaving non-toxic components and purified air. The air then passes over the heater and back into the environment. A fan is also included to move air through the flow path.

In one aspect, the bridge is placed at an intersection horizontal and vertical mullions to divert fluid along the curtain wall system. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A curtain wall mounting system for cantilevered support of at least one structure. The system includes an anchor plate adapted to integrally mount with a web section of a curtain wall. The curtain wall web section includes either a hollow tongue web extending outwardly of the curtain wall vertical mullion or an integrally formed flange region extending outwardly of the curtain wall vertical mullion. The anchor plate has at least one generally planer body portion with a first set of mating apertures adapted for alignment with the first set of fastening apertures of the web. The first set of apertures are oriented generally perpendicular to the tension forces transmitted by the anchor plate. The anchor plate also includes a second set of apertures adapted for securing of structures outwardly from the curtain wall.

Abstract: Commercially available filter-monitoring switches suffer from problems related to over sensitivity and reliability. Accordingly, the present inventors have devised, among other things, various embodiments of filter-monitoring switches and related components, subassemblies, methods, and systems. One exemplary filter-monitoring switch includes a diaphragm operably couple to move a conductive element back and forth between a pair of fixed terminals in response to pressure differences across the diaphragm. The conductive element is mounted to an insulative pin of substantially uniform width, and the terminals include leaf contacts that constantly engage the pin or the contacts throughout normal operation of the switch, thereby reducing flexure of the contacts and effectively providing a self-cleaning and self-healing electrical switch.

Abstract: A computer-based method for maximizing the use of lumber in the production of truss members for a truss assembly using a linear feed saw apparatus. The method comprises storing a list of truss members to be cut by the linear feed saw apparatus, selecting from the list a first truss member for cutting, the first member having a trailing end. A second truss member from the list is selected for cutting, the second member having a first end that will nest with the trailing end of the first member. The second member is oriented such that its first end nests with the trailing end of the first member. The members are then cut using the linear feed saw. The nesting members can abut across the entire member width, only across a portion of the member width or at a single point. The nested ends of the first and second members may be bevel cuts.

Abstract: Disclosed is a moisture collection bridge and method for use in a curtain wall system. In one aspect, the moisture collection bridge is placed at an intersection of a vertical mullion and one or more horizontal members. The moisture collection bridge is formed to collect fluid in a recess and divert the fluid out of the curtain wall system through an outlet.

Abstract: An indicator suitable for signaling restricted flow of a fluid through a filter mounted in a filter indicator includes a housing having an inner cavity. A diaphragm disposed within the housing separates the inner cavity into first and second chambers and deflects from a neutral position in response to applied pressures within the first and second chambers. A tab assembly opposite the diaphragm includes a spring-loaded flag moveable from a first position within the housing to a second position outside the housing. A pin operably coupled to the diaphragm holds the spring-loaded flag within the housing when the diaphragm is in the neutral position. In response to the diaphragm being deflected sufficiently from the neutral position to release the pin, the spring-loaded flag travels to the second position outside of the housing, thereby indicating a restrictive flow condition for the filter.
