Abstract: An opto-electronic data acquisition and storage system, having a light source for directing light along a predetermined light path, a light sensitive electronic memory, a light absorber, a spatial optical storage device being positioned to receive reflected light and to direct the reflected light to the light sensitive electronic memory and a digital light processor having an array of electronically positioned micro-mirrors each being selectively oriented to a reflecting position to reflect light from the light source along a reflected light path to the spatial optical storage device for data storage and being selectively oriented to reflect light from said source to the light absorber when the reflected light is not intended for storage.

Abstract: A reinforced plastic pallet having a plurality of pallet sections each composed of plastic material and having interlocking elements defined by side walls of the pallet sections. At least two of the pallet sections define front and rear pallet edges and each have at least one reinforcing receptacle located adjacent the front and rear pallet edges. At least two elongate reinforcing elements are located within the reinforcing receptacles and are oriented for reinforcing the front and rear pallet edges to minimize bending thereof when the front and rear pallet edges are resting on a rack and under load. The pallet sections are of generally tubular configuration having planar upper and lower walls and parallel side walls. The side walls define dove-tail or other interlocking connectors for securing the pallet sections in immovable assembly.

Abstract: A machine has a support (3) which receives and supports a button shank (6) at a support station (4); a winding device (12) rotates thread (21) through an outlet (25) to wind it around the shank supported in the support under the control of tensioner (17); hooks (56, 57) catch the thread at both ends after bonding the winded thread, the hooks moving as a unit (77) snap the thread to release the shank from the support.

Abstract: A laterally translatable pressure staged rotary shaft sealing mechanism having a seal housing with a shaft passage therein being exposed to a fluid pressure P1 and with a rotary shaft being located within the shaft passage. At least one annular laterally translatable seal carrier is provided. First and second annular resilient sealing elements are supported in axially spaced relation by the annular seal carriers and have sealing relation with the rotary shaft. The seal housing and at least one seal carrier define a first pressure staging chamber exposed to the first annular resilient sealing element and a second pressure staging chamber located between and exposed to the first and second annular resilient sealing elements. A first fluid is circulated to the first pressure chamber at a pressure P1, and a second staging pressure fluid is circulated to the second pressure chamber at a fraction of pressure P1 to achieve pressure staging, cooling of the seals.
