Abstract: ABSTRACT A method of monitoring the ageing or wearing of a spliced endless member such as a belt is disclosed.  The method involves applying to the spliced endless driving belt a pair of first markings the shortest path between which includes the splice of the endless drive belt and applying to the driving belt a pair of second markings the shortest path between which does not include the splice.  During use of the belt the following two measurements are made simul-taneously, namely (1) the time taken for the first pair of markings to pass through a position in which they are sensed by a first element for sensing the presence of the first markings; and (2) the time taken for the second pair of markings to pass through a position in which they are sensed by a second element for sensing the presence of the second markings.  By determining the relation between the two time values thus obtained and comparing this relation with a predetermined value the degree of slackness or wear can be determined.

Abstract: Abstract of the Disclosure A process is described for the preparation of perlite ore fines for expansion.  The ore fines are treated with an agglomerating agent which has a viscous liquid phase at a temperature above ambient temperature but below the critical dehydration temperature of the perlite ore fines.  Suitable agglomerating agents mentioned are the boron acids, particularly orthoboric acid and metaboric acid.  The perlite ore fines and agglomerating agent are mixed, preferably by mixing, and then heated to the temperature of the viscous liquid phase and held at that temperature for a short period while the liquid coats at least a portion of the perlite ore fines and effects agglomeration. Thereafter, the agglomerated perlite ore fines can be expanded in a conventional perlite ore expander.  The resulting expanded materials have properties essentially identical to standard expanded perlite ore and are useful for such purposes as insulating fillers and light weight aggregates.

Abstract: ABSTRACT OF THE DISCLOSURE:         Disclosed is a method for manufacturing a plastic encapsulated semiconductor device and a lead frame therefor.  A semiconductor device assembly is formed, using a lead frame an external lead of which extends to one side of a substrate support serving as a heat sink and supporting a semiconductor substrate, and strips of which extend to the other end of the substrate support.  The external lead and strips are clamped by upper and lower molds for plastic encapsulation.  A connecting portion between the external lead and a connecting band and the strips extending from a plastic encapsulating housing to the outside are cut.         The substrate support is, thus, held properly at the time of plastic encapsulation, preventing bending of the semiconductor device due to injection pressure of the plastic.  Therefore, a thin film of plastic is uniformly and with high precision formed on a lower surface of the substrate support.

Abstract: Abstract of the Disclosure A tensioning device is disclosed for maintaining proper tension of a filter bag assembly.  The device includes a rotationally mounted cam, a torsion spring urging the cam to rotate in one direction, and a cable trained around the cam opposing the force exerted by the spring.  Due to the shape of the cam, the cable force may be exerted at continuously varying distances from the axis of rotation of the cam.  The spring, cam, and cable are arranged such that when the spring exerts a relatively high force on the cam, the cable force is exerted a further distance from the axis than when the cam is in a rotational position such that spring force is relatively low.  A substantially constant cable force is accordingly exerted.  The device is secured between the filter bag and a supporting structure of a baghouse. Constant tension is main-tained even if the bag changes in length as the varying spring force is compensated by the cable acting upon the cam at different points.

Abstract: METHOD FOR DEFINING SUBMICRON FEATURES              IN SEMICONDUCTOR DEVICES            Abstract A method for forming a guard zone is disclosed, suitable for a guard ring for a Schottky barrier diode or for a channel guard zone for protecting the channel inversion layer of an insulated gate field effect transistor.  The method uses anistropic (straight-line) etching of a window in a thermally grown silicon dioxide layer on a silicon body combined with deposition of a metallic masking layer, such as aluminum, which is subject to a shadow effect of reduced thickness at a sidewall of the window.  Slight etching of the metallic masking layer results in an aperture at the resulting edges of the masking layer located in the vicinity of the sidewall of the thermally grown oxide layer.  Ions are then implanted with the body through the aperture, to form the guard zone.
