20130214098 | TOP BEAM CLAMP - 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 āCā 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. | 08-22-2013 |
20130206927 | Threaded flange plate for hanger rod - 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. | 08-15-2013 |
20130126681 | Threaded brackets for hanger rod - 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. | 05-23-2013 |
20120263553 | WEDGE ANCHOR HAVING FEMALE THREADS AND TIGHTENING NUT - The present invention relates to a captive wedge acting fastening device with a female thread and method for inserting said device into a hole in masonry, concrete, stone, or other aggregate materials while it is attached to a fastener or hanger without rotating said hanger or fastener. | 10-18-2012 |
20080256494 | TOUCHLESS HAND GESTURE DEVICE CONTROLLER - 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. | 10-16-2008 |
