Abstract: A pump includes a housing defining a tube receiving portion and a blade mounted for reciprocating movement between first and second positions. In its first position, the leading edge of the blade compresses a length of tube against a first surface disposed in the tube-receiving portion, while in the second position, the blade does not compress the tube. The tube-receiving portion can receive the tube directly or indirectly through a tube set detachably mounted to the housing. The tube set includes a tube and a base having first and second end portions that respectively define first and second tube-receiving apertures for slidably receiving a length of the tube therethrough. The base has a first surface constructed to engage the length of tube between the apertures for compression by the pump blade.

Abstract: A window frame including a pair of identical frame halves that can be interconnected without fasteners. Two different connector systems are integrally formed with the frame halves, and the frame halves have two possible orientations with respect to one another—a ship orientation and an install orientation. The first connector system releasably interconnects the frame halves in either orientation. The second connector system essentially permanently interconnects the frame halves only in the install orientation—not in the ship orientation.

Abstract: The present invention is directed at methods and apparatus for controlling multi-source heating systems. The multi-source heating systems of the present invention may include two or more heat sources such as a heat pump, a furnace, an electric heating strip, or any other suitable heat source. An illustrative system includes a multi-zone, multi-source heating system. The illustrative system may determine which of the multiple sources to use depending on a number of factors.

Abstract: A method of producing metal fibers including melting a mixture of at least a fiber metal and a matrix metal, cooling the mixture to form a bulk matrix comprising at least a fiber phase and a matrix phase and removing at least a substantial portion of the matrix phase from the fiber phase. Additionally, the method may include deforming the bulk matrix. In certain embodiments, the fiber metal may be at least one of niobium, a niobium alloy, tantalum and a tantalum alloy and the matrix metal may be at least one of copper and a copper alloy. The substantial portion of the matrix phase may be removed, in certain embodiments, by dissolving of the matrix phase in a suitable mineral acid, such as, but not limited to, nitric acid, sulfuric acid, hydrochloric acid and phosphoric acid.

Abstract: The present invention concerns a process for preparing 4-(hydroxy)-[1,4′]bipiperidinyl-1′-carboxylic acid tert-butyl ester, comprising hydrogenating a mixture of 4-hydroxypiperidine and 1-tert-butoxycarbonyl-4-piperidone in a suitable solvent, in the presence of a suitable catalyst and at a suitable pressure.

Abstract: A system and method for mitigating the effects of low power line voltage that can otherwise cause premature lamp mortality. A monitor circuit is provided for monitoring power characteristics relating to UV and/or fluorescent lamp operation, such as the lamp supply voltage or the current traversing the lamp. A controller operates in conjunction with the monitor circuit. The controller receives a signal indicative of the state of the monitored power characteristics, and temporarily interrupts the power to the lamp when the signal indicates that the power source is currently failing to maintain a stable current flow through the lamp. Power is therefore removed from the lamp during periods of brownout or other low voltage conditions to prevent accelerated lamp mortality.

Abstract: A single-mode optical waveguide with a core, surrounded by a cladding consisting of an inner soft layer and an outer harder layer is described. The outer layer has a grating structure on its inner surface, whose spatial frequency is the same as that of the guided mode. The thickness of the inner cladding is sufficient to keep the grating outside the mode field in undeformed regions of the waveguide, so that normally no out-coupling of the light results. Connections are made by crossing two such waveguides at an angle and pressing them together. This results in deformation of the two waveguides such that the gratings are brought into proximity with the cores. Light is coupled out of one waveguide and into the other in the deformed region, resulting in a self-aligning optical connection. The out-coupled light propagates normal to the waveguide axis, so errors in the crossing angle cause little change in efficiency.

Abstract: A system, apparatus, and method for preventing thermal cycling of a ballast coupled to one or more lamps. A monitor circuit is provided to monitor for activation of the ballast's thermal protection mechanism. Such monitoring may include monitoring of the ballast's thermal protection mechanism itself, or monitoring lamp current and ambient temperature in the vicinity of the ballast to determine that the ballast's thermal protection mechanism has been activated. Power to the ballast is temporarily disabled when the ballast's thermal protection mechanism has been activated, thereby preventing thermal cycling of the ballast, and consequently of the lamps, when power to the ballast has been removed.
