    摘要： A method of making a thermistor comprising the steps of making a layer of thermistor ceramic material comprised substantially of Mn.sub.2 O.sub.3, NiO, Co.sub.3 O.sub.4, Al.sub.2 O.sub.3, CuO, or Fe.sub.2 O.sub.3, having upper and lower surfaces. A first dielectric material comprised of low K Al.sub.2 O.sub.3 or the like is placed on the upper and lower surfaces of the layer, and then is cut into a plurality of elongated strips. The layer is created by blading a slurrey of the ceramic material to create a plurality of uncured sheets; placing the sheets in superimposed position, and then making the monolithic layers from the sheets by applying heat and pressure thereto, and then firing the monolithic layer with heat of increased magnitude. The strips are encapsulated in an envelope of the dielectric material, and terminal connections comprised of silver, Ni, Sn and Pb are imposed thereon. A thermistor chip or strip comprising an elongated ceramic thermistor body with an outside surface and opposite ends. A dielectric envelope encapsulates the outer surface of the body for the ends, and conductive terminal caps are formed on the end of the body. The thermistor is comprised of the materials outlined in the method of making the same.

    摘要： An improved crankcase structure and manufacturing method for engine blocks and the like wherein the crankcase is initially cast or otherwise formed with bearing caps integral therewith. The caps are preferably secured by severable connecting portions unidirectionally longitudinally adjacent their associated bearing receiving portions in the transverse webs of the cylinder block. The complete crankcase is then machined and the bearing caps are separated for subsequent assembly to the crankcase in conventional fashion. The invention reduces the amount of tooling and machining time and equipment required for manufacturing crankcases for engine blocks and the like.

    摘要： A method and apparatus of applying stocking sheaths to cylindrical articles involving passing the articles longitudinally through the interior of a cylindrical mandrel bearing on its outer surface a supply of continuous stocking material. As the articles emerge from the mandrel they pickup overhanging stocking material and draw it off the mandrel. The interconnecting stocking between successively emerging articles is severed by shearing means. Spacing sufficient to provide stocking portions overhang the ends of the articles is achieved by driving the articles emerging from the mandrel at a greater speed than they are driven through the mandrel. Filter elements are formed of hollow, fibrous cylinders covered with a cloth stocking by tucking the overhanging ends of the stocking into the hollow ends of the cylinders.

    摘要： A machine and method for mechanically and simultaneously sizing and cutting multiple strands of flexible metallic conduit to desired lengths, and for facilitating the application of a fitting to either end of the respective resulting lengths, in which the conduit is simultaneously drawn, by a roller drive, from a number of rolls of same in parallel strands and is fed past a cutting station the conduit length desired, after which feeding of the conduit strands ceases and the conduit lengths are simultaneously severed from the row of strands by sawing. The machine includes a device for mechanically rotating the individual end fittings for the conduit length ends, whereby the machine operator can individually manipulate the individual conduit length ends to apply same to the device to permit the end fitting for same to be mechanically rotated into its fully seated position in the conduit end, and an attachment that permits the conduit wiring to be mechanically fed into same and cut off at the right length to complete the conduit assembly.
