Title: Method for operating a device for testing the leakproofness of watches and other hollow bodies
Inventor: GREINER RUDOLF
IPC: G01M3/36
Filed: 1983-04-11
Abstract: In testing the leakproofness of a watch (2) or other hollow body, the internal volume (V) of the test specimen is considered. In this case, the deformation (hp-ho) of the base (9) is measured under increased pressure (p) by the sensor (11). In the event of a predetermined permissible leakage rate (PLz, e.g. 50  mu g/min), it is not permissible for the regeneration ( DELTA h) effected by the leak to exceed a permissible value ( DELTA hz) within the measuring time ( DELTA t). This value ( DELTA hz) is computed by the microcomputer (3) with the aid of the measured hp-ho- and the input  DELTA t,p,V data upon attainment of the test pressure (p), the same applying to the result of the test after expiry of the test time ( DELTA t). Said result is displayed by means of lamps (NG, OK) or on the instrument (15). <IMAGE>

Title: Process for the purification and liquefaction of coal
Inventor: BROWNE WILLIAM G
IPC: B03B9/00
Filed: 1983-08-02
Abstract: A coal purification process for removing substantial mineral substances from coals of high ash content, using a liquid originating from coal, with the use of the liquid originating from coal for agglomeration. In the process, particulate coal is mixed with sufficient water to prepare a flowable suspension, and a hydrocarbon liquid originating from coal is intimately mixed with the coal/water suspension to provide agglomerated coal particles. By screening the resulting coal/water/hydrocarbon liquid mixture, a part of the coal containing increased quantities of the mineral substances settles and an upper coal/oil part of agglomerated coal particles having a reduced concentration of mineral substances is removed and dried for the removal of water down to less than about 25 % by weight. The purified and dried coal/oil material is advantageously fed to a coal liquefaction process for the production of liquid and gaseous hydrocarbon products, and a hydrocarbon liquid originating from coal is recycled to the coal purification stage for producing the agglomerated and purified coal particles.

IPC: H03K17/10
Filed: 1983-09-30
Abstract: In a switch consisting of at least two series-connected field-effect transistors (F1, F2, F3, ...), a control voltage (USt) is applied to the first field-effect transistor (F1). The other field-effect transistors (F2, F3, ...) are connected to one another by in each case one Zener diode at their gates. The gate terminals of the other field-effect transistors (F2, F3, ...) are driven from an auxiliary voltage source (UH). An overvoltage protection diode (D11, D12, ...) is in each case connected in parallel with the gate-source capacitances (C11, C12, ...). After the first field-effect transistor (F1) has been turned on, the gate-source capacitances (C11, C12, ...) of the other field-effect transistors (F2, F3, ...) are charged up in succession and these transistors are turned on. After the first field-effect transistor (F1) has been turned off, the gate-source capacitances (C11, C12, ...) of the other field-effect transistors (F2, F3, ...) are recharged. <IMAGE>

Patent DE-3407490-A1 (DE)
Title: Process for repairing refractory linings
Inventor: MARTENS THEOPHILE
IPC: F27D1/16
Filed: 1984-03-01
Abstract: The invention relates to a process for repairing a damaged refractory lining in the hot state by spraying on a pulverulent refractory material heated to a high temperature. 
<??>In particular, the repair of the refractory lining of coke ovens is provided, in which wear of the refractory lining occurs as a result of cracking or flaking off because of thermal and mechanical loadings during service. The known deposition of oxides of combustible metals such as aluminium, silicon or magnesium is very expensive because of the consumption and the price of these metals. The melting of refractory material with high-temperature flames is also expensive since in addition to the fuel, oxygen generally also has to be used. The invention improves the known processes in that the refractory material is heated in the pulverulent state to the particular temperature required using a plasma torch and then sprayed onto the defect in the lining. This not only aids the repair even of places which are difficult to access but also considerably reduces the duration of the repair work with low material consumption whilst the plasma temperature can be sensitively controlled in wide ranges so that undamaged regions in the vicinity of the defects are not affected by overheating.

Title: Process for hot-isostatic pressing of porous bodies
Inventor: ZEILINGER HANS DR
IPC: C04B35/645
Filed: 1984-06-14
Abstract: In the process described here for hot-isostatic pressing of porous bodies, in which the moulding, which was cold-precompacted or sintered from a powdered material, is encapsulated and then subjected to isostatic pressure at high temperature, encapsulation of the moulding prior to pressing is effected by chemical deposition of metals or metal alloys having a high melting point from the vapour phase (CVD) onto the surface of the moulding. Such an encapsulation with ductile metals, for example molybdenum or tungsten, is technically easy and, from as low a layer thickness of the capsule material as approximately 1  mu m, provides a tight seal, which is thermomechanically stable up to more than 2000 DEG C, of the surface pores of the moulding to be pressed, even in the cavities thereof.
