Abstract: A table edge mountable U-shaped channel slot device having two spaced arms extending from a base with a slot therebetween. The elevation of the opening at the front of the channel is lightly less than the elevation of the slot at the base. The device is formed from a slightly flexible rigid U-shaped plastic channel overlaid exteriorly only with a wrap layer that may be neoprene. Optionally a layer of a thin rubber sheet is disposed over the interior surface of one arm. The device is adapted to fit over the edge of a table such as a commercial folding table to provide forearm comfort and cleanliness for bingo players by helping the forearm to avoid chemical residue, splinters, dirt, cigarette sears and impact of the hard table edge. Preferably the corners of the arms distant from the base are chamfered.

Abstract: A sheet restraint for a sheet shipping rack includes a first elongated tube rotatably mounted on a second elongated tube. The second tube has U-shaped member secured to each end to capture the first tube on the second tube while allowing the first member to rotate relative to the second member. A resilient elongated sheet engaging member is secured to the first member. A pair of spaced pins are mounted on the first member and engageable with the U-shaped member to limit rotation of the first member about the second member so that the rotational path of the sheet engaging member and first tube is limited. The engaging members on the second tube are slideable mounted to spaced standards at the front of a rack. In this manner the front restraint moves toward the base into engagement with the outermost sheet of a stack of sheets on the rack to maintain the sheets as an integral pack.

Abstract: A piezoelectric acoustic transducer for coupling acoustic energy to a gaseous atmosphere in a pulse-echo ranging system has a tubular housing closed at one end by a thin integral wall to which a radiating plate of a transducer assembly is coupled to radiate acoustic energy by means of a layer of acoustically transmissive matching material. The transducer assembly except for its radiating surfaces is wrapped in an acoustic decoupling material such as cork, and the side wall of the tubular housing, which has a mounting ring behind the transducer assembly, is also internally lined with such material, space around and behind the transducer assembly within the housing being filled with a slightly elastomeric potting compound. This arrangement decouples the mounting ring from the transducer assembly, thus stabilizing the ringing characteristics of the transducer.
