A lacquer coating is applied to a laminated metal composite forming a sliding element such as a plane bearing and has particles of solid lubricants incorporated therein to form islets of greater thicknesses than the surrounding film and which serve as lubricant-trapping surface formations. The particles may be of polytetrafluoroethylene, fluorinated graphite or molybdenum disulfide and the lacquer...

Yarns are deposited on a conveyor belt in the form of random or ordered loops and are conducted through a yarn treating chamber. The treated yarn is drawn from the belt at a predetermined draw-off site. The position of the last yarn loop adjacent the draw-off site is scanned by a sensor, and the draw-off velocity is controlled as a function of deviations in the location of this last yarn loop. At ...

To splice slubbing, sliver, roving or yarns, they are twisted together and after bonding, are twisted back against the direction of splicing rotation. Pref. the spliced material is twisted back pneumatically. Before splicing, the ends to be joined are twisted open pneumatically, and any part not needed for the splice is blown clear at the same time as the ends are twisted open. ADVANTAGE - Method...

Winder, for synthetic multifilaments, has a friction surface as the cutter, with a grinding or emery character at the yarn guide. Pref. the yarn guide is the suction opening of the yarn suction system. The winder has two bobbin spindles, operated alternately. The yarn guide deflects the multifilament yarn from the fully wound bobbin to the new winding station, and carries it from one spindle to th...

A creel frame has a series of creel pegs and yarn guide tensions on a vertical stand, opposite each other, and an arrangement for a relative change of position. Pref. the construction of the frame is from tubular support bars. The base (1) is formed with brackets (17) to hold the castors (16) which allow the frame to be moved multi-directionally. ADVANTAGE - The creel pegs, when holding the reel, ...

A fiber guide includes a sleeve having a longitudinal slot therealong a first member, having a notch, is fixed in the sleeve with the notch substantially aligned with the slot. A second member, also having a notch, is rotatably disposed in the sleeve. Thus, a fiber can be positioned in the notches of the first and second members and secured therein by rotating the second member. The fiber can also...

PURPOSE:To increase the number of picture elements without reducing the gap between electrodes by dividing the display screen of each liquid crystal panel into a display area and a non-display area, and superimposing the non- display area of another liquid crystal panel on the display area of one liquid crystal panel. CONSTITUTION:The display screen of the liquid crystal display panel 4a out of th...

PURPOSE:To prevent disconnection of electrode in use by forming a back metal electrode into a predetermined pattern, and then coating the whole display surface with an insulating material of specified thickness, and subjecting the surface to aging treatment, and further laminating the insulating material to specified thickness. CONSTITUTION:After the back electrode 6 of a thin film electroluminesc...

PURPOSE:To ensure the long life of a dispersed type electroluminescent element even in use in an environment where ultraviolet rays are abundant by forming a layer containing supermicro particles of titanium dioxide between a light- emitting layer and a surface side moistureproof film. CONSTITUTION:Supermicro particles 9 of titanium dioxide are disposed between a light-emitting layer 3 and a surfa...

PURPOSE:To enhance the electrical properties of an electroluminescent element by opposing a light-emitting layer of specified surface roughness to a transparent electrode layer formed on a transparent insulating film via the rough surface of the light-emitting layer, and laminating and integrating both layers together. CONSTITUTION:A light-emitting layer 3 containing phosphor particles distributed...

PURPOSE:To realize the high brightness and long life of an electroluminescent fluorescent material by specifying the number and diameter of conductive needle phases provided inside particles and using sulfides as bases.
