Abstract: A modular LED lamp system allows for stacking multiple LED carriers to provide the desired amount of light. Each LED carrier preferably includes its own transformer to convert line voltage to power useable by the LEDs on the carrier. Line voltage is conducted through each module to a subsequent module and is provided to the transformer.

Abstract: An electrical receptacle that is normally configured to receive AC voltage is configured to provide a low voltage DC instead. An LED bulb without a transformer can be plugged into the appliance and operate on the DC voltage from the wall outlet. An optional circuit interrupter can prevent damage to the LED bulb is it is inadvertently plugged into a source of AC voltage. Any appliance designed to be operated on DC voltage can be plugged into the DC outlet without a transformer. Multiple LEDs can be “piggybacked” onto a base.

Abstract: End caps that attach to any standard tubing to facilitate mounting a tube with LEDs into an existing fluorescent lamp cabinet. The tube can be cut to a desired length. The end caps can be supported by the fluorescent fixtures or mounting brackets in the cabinet. An assembly comprising a light emitting diode (LED) lamp for replacing fluorescent tube lights.

Abstract: An adaptor enables mounting of light-emitting diode (LED) modules onto pre-existing support elements, such as tubing, while avoiding problems with current mounting methods. The adaptor may be installed on the back side of any LED light module to enable a snap-on installation of the LED light module to tubular mounting hardware. The adaptor is held onto the tubular hardware by spring tension jaws designed into the manufacturing process of the adaptor. In the configurations disclosed adaptors can be manufactured to conform to any cross-sectional shape of the support element, including: square, triangular, rectangular, pentagonal, hexagonal, “I”-shaped, “L”-shaped, and round, over a wide cross-sectional dimension range. The adaptor may be mounted onto all industry-standard LED light modules with double-sided adhesive tape to allow quick and simple installation of the LED light module to any type or configuration of support element, which may be oriented horizontally, vertically or at various angles.

Abstract: An LED support clip enables mounting of light-emitting diode (LED) modules onto support elements which may be pre-existing, such as tubing, while avoiding problems with current mounting methods. One or more LED light modules may be clamped into the LED support clip without the need for adhesives or screws, thereby forming an LED light assembly. One or more LED light assemblies may be clamped onto the support element. The LED support clip may comprise multiple clamps configured with spring tension jaws designed into the manufacturing process of the LED support clip. Support elements may be oriented horizontally, vertically or at various angles and may have a variety of cross-sectional shapes, including: square, triangular, rectangular, pentagonal, hexagonal, “I”-shaped, “L”-shaped, and round, over a wide cross-sectional dimension range.

Abstract: The invention is directed to a divider block assembly made from one piece of material. Traditional divider blocks require modular sections so that piston alignment can be calibrated precisely. The current invention uses replaceable pistons and sleeves that are suitable for use at high fluid pressures. The use of these pistons also allows for a single, bodied, one-piece, metal divider body, rather than the conventional multiple block divider blocks, which allows for a more efficient manufacturing method and stronger, more reliable, and more efficient lubricant dispensing system. The use of any of these aspects separately can improve performance, and not all are required in every embodiment.

Abstract: A device is provided to prevent the accidental introduction of an incorrect liquid into a tank, such as the introduction of gasoline into the fuel system of a diesel fuel container. The device discriminates between nozzle diameters, allowing entrance of nozzle diameters at or greater than a predetermined minimum diameter while inhibiting entrance of nozzles having diameters less than the predetermined minimum diameter. A closure mechanism prevents access to a fuel container interior and a releasable locking mechanism responsive to nozzle diameters allows the closure mechanism to open and close to allow access to the fuel container interior.
