Abstract: In a storage receptacle for a magnetic tape cassette comprising a housing having spaced apart, parallel side walls which, between their forward edges, define an opening of the housing, and a holder pivotally connected with the housing for swinging movement through such opening between an opened position in which the holder projects forwardly from the housing for receiving and relinquishing a cassette, and a closed position in which the holder cooperates with the housing for enclosing a cassette in the receptacle; the pivotal connection of the holder with the housing provides a fulcrum for the holder which is spaced rearwardly from the center of gravity of the holder with a cassette therein in all positions of the holder ranging from its closed position to its opened position so that the force of gravity urges the holder from its closed position to its opened position upon the release of a latch provided for releasably retaining the holder in its closed position, and such fulcrum for the holder is shifted forwardly at an intermediate position of the holder in moving from its closed position to its opened position so that, even when the vertical dimension of the rectangular housing does not greatly exceed the corresponding dimension of the cassette to be contained in the receptacle, a lower-front corner of the holder will not extend below the housing in the opened position of the holder at which the latter is disposed for conveniently receiving or relinquishing a cassette in the holder.

Abstract: Disclosed is an improved method for manufacturing an object of silicon nitride. In the method, a body preformed from silicon nitride powder and enclosed in a casing of glass is isostatically pressed with a gaseous pressure medium in a pressure vessel at a temperature required for sintering of silicon nitride. After pressing and sintering are completed, the pressure and the temperature in the pressure vessel are adjusted such that the temperature maintains the glass in a plastic state and the pressure in the pressure vessel is below the partial pressure of nitrogen gas for silicon nitride at that temperature so that the glass casing is blown up around the body and the body is freed from or can easily be freed from the glass casing.

Abstract: . ` A process for calcining mineral raw materials is performed in a two-shaft furnace wherein each of the shafts are alternately used as the calcining shaft and as the counterflow shaft.  Fuel is supplied in the calcining shaft by means of burners at the end of a preheating zone and the mineral raw material is calcined in a calcining zone.  Generated exhaust gases flow upwardly into the counterflow shaft, heat up the raw material in the shaft and leave through an exhaust.  The calcined raw material is passed through an after-deacidification zone and, subsequently, through a cooling zone in which it is cooled by means of cooling air which is blown in from below.  After removal of dust, the heated cooling air is either entirely or partially conveyed either directly into a raw material preheater or  it is utilized in a recuperator for heating combustion air.

Abstract: A process is described in which coal and/or coke are/is gasified by reaction with water vapor in the presence of a suitable metal and/or its oxide. The products of the process are combustible gas, essentially carbon monoxide and hydrogen, and metal. The relative quantities of the products are chosen at will, e.g. according to the demands of the market, by appropriate choice of proportions of input raw materials. The process is limited to metals that catalyze the gasification and that can be produced by reduction of their oxides with the aid of coal and/or coke. Such metals are such as belong to the group iron, cobalt, and nickel. When iron and/or iron oxide is used, the process is conducted in the temperature range 728-1490 DEG C preferably at about 1150 DEG C, and at essentially the pressure of the ambient atmosphere. An essential part of the process is the purification of the gas, especially with respect to sulfur and metals, the sulfur being in the form of hydrogen sulfide, the metals being in the form of vapors of metals or metal oxides. This is done by known methods, e.g. cooling and treatment with bog ore.
