Abstract: A demountable pin for rotatably connecting together two elements of small axial dimension, consisting of a bolt with a frusto-conical under-head and an inner hexagonal through bore for tightening it by a key. The pin is locked between two frusto-conical flares of the elements by an end nut with a frusto-conical under-head and a washer with a frusto-conical surface of greater taper than the flares. The under-heads of the nut and the bolt cooperate with the flares.

Abstract: An apparatus and method for assembling electrical connector components, including headers, connectors, and terminals, to circuit bearing substrates functions to align the terminal pins of a connector or header into a preferred position and install an annular solder preform onto each terminal pin. The pin alignment apparatus includes movable jaw plates the define a variable size aperture for encompassing each of a plurality of terminal pins, including terminal pins that are bent or skewed relative to an intended position. A carrier plate overlies the jaw plates and includes a plurality of cavities for receiving solder preforms to be installed over each of the terminal pins. The jaw plates are positioned over the terminal pins and moved to a closed position to align all the terminal pins, including any bent or skewed terminal pins, to an intended alignment.

Abstract: An improved process for delignifying and bleaching nonwoody, lignocellulosic material into products digestible by ruminants and ingestible by humans. The process comprises treating the substrate in an alkaline solution for a period of time, separating the wetted substrate from the slurry and then treating the wetted substrate with an alkaline peroxide solution at an initial pH of 8.5 to 11.0 for a period of time, and separating, washing and drying the product.

Abstract: A device for attaching a tool in portable angled grinders, allowing the connection to be released without special accessories. The device consists essentially of a hollow driveshaft, of a spindle that slides inside it, and of a tool-securing point consisting of a mating flange and nut. The nut is loosened by activating the displacing mechanism, which displaces the spindle toward the tool-securing point, lifting the nut, which is connected to the spindle by means of a threaded pin, off of the tool. The nut can then be screwed off by hand.
