Abstract: ABSTRACT A multiple substantially identical countershaft (16, 16A), simple change gear transmission (10) having two-piece (20, 20A, 22, 22A) countershafts is provided. The use of two-piece countershafts allows the countershafts to be supported by three bearings (72, 74 and 76) while not requiring greater than normal manufacturing accuracy of the transmission housing (H).  A driving connection between the front and rear countershaft portions is utilized which will allow a degree of axial misalignment between the front and rear portions and which when connected assures proper circumferential alignment of the countershaft gears.  In the preferred embodiment, proper circumferential alignment of the front (20, 20A) and rear (22, 22A) countershaft portions is assured by providing a splined connection between the countershaft portions wherein the number of spline teeth (37, 66) is even divisible into the number of countershaft gear teeth carried by any gear on one of the countershaft portions (22, 22A) and wherein each spline tooth carried by the one countershaft portion has the same circumferential alignment with the countershaft gear teeth carried by said one portion as all of the other spline teeth carried by the one portion.

Abstract: 22                 46,767 ABSTRACT OF THE DISCLOSURE Impurity regions and preferably buried impurity regions are formed of desired thicknesses and concentra-tion gradients in semiconductor bodies at a given distance from a selected surface of the body.  A high energy ion beam of greater than 1.0 Mev. containing ions of an impur-ity to form a desired impurity region in the semiconductor body is formed to penetrate the body through the selected surface  to  a distance  sufficient  to  form the impurity region.  A beam modifier is formed of a given material and non-uniform shape to modify the ion energies on transmis-sion throughout to form the impurity region of a desired thickness and concentration gradient at a given distance from the selected surface of the semiconductor body on irradiation of the semiconductor body through the selected surface with the transmitted high energy ion beam.  The semiconductor body  is  then positioned to be irradiated with the high energy ion beam through the beam modifier, and  the  semiconductor body  is  so  irradiated until the impurity region of the desired thickness and concentration gradient is formed in the body at a desired distance from the selected surface.   Preferably,  there is a predeter-mined  relative  movement between  the beam modifier  and semiconductor body during irradiation to modulate the ion beam as desired to form the impurity region.  The semicon-ductor body is also preferably annealed after irradiation to remove detrimental electrical characteristics caused by the irradiation from the semiconductor body,

Abstract: ABSTRACT OF THE DISCLOSURE        The disclosure describes a method of processing sulphidic zinc ores and/or concentrates by leaching the same with cell acid such as sulphuric acid, and separating the leach and leaching residue.  The leaching residue is dried and resmelted, and the leach is purified for subsequent electrolysis for the purpose of recovering zinc.  The leaching is carried out with sulphuric acid under oxidizing conditions with the formation of elementary sulphur.  The leaching residue is resmelted with combustion of elementary sulphur, into a disposable slag, with the simultaneous formation of a sulphidic matte for the absorption of copper, lead and noble metals, and a waste gas.  The highly volatile metals and metal compounds remaining in the leaching residue are volatilized and pre-cipitated.  This method enables to produce a disposable slag economically, with a reduction in the amount of energy and equipment required.
