  • Patent number: 8882056
    Abstract: A pipe hanger clamp, formed by bending a flat section of metal bar or plate, has two vertical side members which have been cut so their side view is a ā€œCā€ shape. The lower arms of these two side members are joined by a horizontally extended end wall, about which the side members are bent. Holes in the end wall receive a mounting set screw into a captured nut and another nut to hold a pipe hanger rod for supporting a pipe. An overhead support is clamped between the set screw and the upper arms of the C-shaped side members, such that the load applied to the rod is generally edgewise to the plate thickness, and does not provide an unbending force on the clamp.

  • Publication number: 20130206927
    Abstract: A mounting assembly utilizing a shaped plate for connection to a threaded rod. A method of creating cuts to clamp about a second internally threaded plate and then deforming those cuts to provide secure fixation of the threaded plate in the first member to permanently hold and prevent movement of the internally threaded plate forming an assembly. The shaped plate having holes within it for mounting the assembly on a flat surface using suitable fasteners.

  • Publication number: 20130126681
    Abstract: A mounting member for a ceiling or beam utilizes a barrel nut for connection with a hanger rod of a pipe hanging support. A technique of creating a riveted joint with a keyed hole to join the barrel nut and then deforming that portion of the rivet into the key way to provide secure fixation of the nut in the member to prevent rotation of the nut when the hanger rod is turned.

  • Publication number: 20080256494
    Abstract: A simple user interface for touchless control of electrically operated equipment. Unlike other systems which depend on distance to the sensor or sensor selection this system depends on hand and or finger motions, a hand wave in a certain direction, or a flick of the hand in one area, or holding the hand in one area or pointing with one finger for example. The device is based on optical pattern recognition using a solid state optical matrix sensor with a lens to detect hand motions. This sensor is then connected to a digital image processor, which interprets the patterns of motion and outputs the results as signals to control fixtures, appliances, machinery, or any device controllable through electrical signals.

  • Patent number: 6152412
    Abstract: A pipe hanger has a tubular section which is split axially so that the tubular section can be opened and fit around a pipe. Two partially overlapping tabs extend from the tubular section. When the tabs are urged together, holes in the tabs become aligned, and permit a single fastener to secure the tabs together, and to affix the hanger to a support structure. The hanger therefore requires only a single fastener. The fastener is preferably supplied with the hanger, and is held by friction in one of the holes in the tabs, or in a tubular chamber extending from one of the tabs. The shape of the tubular section facilitates manual closing of the tubular section around the pipe. The hanger is very easy to install, even when the hanger is located in an inconvenient position.
