Patent DE-3030025-A1 (DE)
Title: Sepn. of ash and ballast particles from powdered coal - aided by thermal outgassing of coal to lower its density
Inventor: NOACK ROLF DR ING
IPC: B03B9/00
Filed: 1980-08-08
Abstract: Prepn. of a substantially ash- and ballast-free coal powder comprises (i) coarse purificn., (ii) in-the-mill drying, (iii) heating the fine powder produced until softening and gas evolution give hollow coal particles of low density, and (iv) sepg. the mixt. by known processes of air- or wet-sepn. Step (iii) can comprise pre-oxidation followed by rapid out-gassing in a gas stream; or fluidised bed or other known techniques may be used. Part of the gas produced can be used in the process, but most goes after purificn. for other industrial or domestic use. The gas contains most of the S in the coal, leaving the sepd. coal powder substantially S-free. Used to give coal powder suitable for replacing oil and gas in combustion systems. Step (iv) gives more complete sepn. of impurities from the coal than before, because the density difference is increased. Less ash is subsequently deposited from burner off-gas.

Title: Individual domestic equipment current consumption meter - has pulse generator and counter in housing with plug and socket
Inventor: GEYER HERMANN DIPL ING
IPC: G01R21/133
Filed: 1980-09-03
Abstract: A current consumption meter, esp. a subsidiary meter which measures the consumption of individual pieces of equipment in a system connected to a main meter, is small, convenient, and can be connected by lay people. It can measure the current consumption of domestic equipment which is normally plugged into mains sockets. A pulsed signal whose frequency depends on the current level in a load (1) is fed to a counter (6). The pulses are counted over a period governed by a timer circuit (10,11). The circuit is contained in a housing with plug and socket connections. The measurement period may be selected as 1,7 or 14 days by using a time selection switch (9). Light emitting diodes (7) controlled by a switch (8) can display the stored count result. A further LED (14) is connected to a frequency divider (13) which reduces the pulse frequency.

Title: Automatic reversing mechanism for washing machines - having two interlinked epicyclic gear trains which are braked alternately
Inventor: MEEK ROBERT ANTHONY
IPC: D06F37/40
Filed: 1980-10-21
Abstract: Reversing drive for, partic. washing machines, or tumble driers, comprises two epicyclic gear trains with a common input shaft, whereof the annulus of one train rotates, in the opposite direction to that of the second annulus, and by applying a brake to each annulus in turn the output shaft can be given an alternating rotation. Brakes are applied alternately by an automatic rocking mechanism which flips from one brake to the other, and which is operated by intermittently-driven cams which are driven at a rate dependent on, but only a fraction of, the speed of the input shaft. This is a relatively simple and inexpensive construction, giving a high-speed, low.torque transmission for which light-weight gears of, e.g. plastic material can be used.

Title: Process for producing oriented short-fibre webs
Inventor: SIEGLING HANS FRIEDRICH
IPC: D21J7/00
Filed: 1981-02-17
Abstract: A process is proposed for producing webs of oriented short fibres for composite materials. A fibre suspension is directed as a continuous stream parallel to a porous wall through which the suspension fluid passes by means of a pressure gradient at a velocity which is less than the flow velocity of the fibre suspension while the fibres are deposited on the porous wall in an oriented state. To enhance the orientation of the fibres or to achieve multidirectional orientation the porous wall is set in motion, the direction of motion of the porous wall being other than the direction of flow of the fibre suspension.

Title: Percussion drilling machine with a device for changing over from rotary drilling to percussion drilling
Inventor: GEIS WILHELM ING GRAD
IPC: B25D16/00
Filed: 1981-04-16
Abstract: A percussion drilling machine with a device for changing over from rotary drilling to percussion drilling, the change-over device having a slide displaceable transversely to the axis of the drilling spindle. The drilling spindle, which is under the effect of a compression spring, is supported on the slide in the "rotary drilling" position and thereby keeps a notched disc, attached to the drilling spindle, disengaged from a second notched disc, fastened to the housing, of a catch means serving to produce blows. The slide is provided with a bore which permits an axial displacement of the drilling spindle in the "percussion drilling" position. The percussion drilling machine is to be improved to the effect that the change-over device is made simpler with regard to its construction and its mode of operation and in addition also takes up less space than the known devices of this type. This is achieved by the slide being provided with a nose-shaped extension which is guided in a helical recess of a change-over pin rotatably mounted in the machine housing.

Title: Method for a diaphragm pump to prevent diaphragm overstretching
Inventor: STAHLKOPF FRIEDRICH
IPC: F04B43/107
Filed: 1981-05-27
Abstract: The invention relates to a method for a diaphragm pump to prevent diaphragm overstretching and can preferably be used in a hose-diaphragm pump, in which the primary working medium loads a tubular hose diaphragm on the inside. The method and the device for carrying out the method ensure that, when the conveyance of the secondary medium is interrupted on the suction side, primary working medium is not sucked up from the storage reservoir in each suction stroke via the top-up valve and conveyed into the pump chamber during the delivery stroke, with the result that an overstretching of the hose diaphragm and finally its destruction can be caused. This is achieved in that, when the conveyance of the secondary medium is interrupted on the suction side, an automatic ventilation or gassing of the secondary medium remaining in the diaphragm pump takes place, the system vacuum on the secondary side, which controls the ventilation or gassing in the suction phase, being lower than the system vacuum on the primary side which controls the balance of primary working medium during normal operation. In the device for carrying out the method, between a suction valve and a shut-off flap or interruption point a ventilation or gassing tube opens into a suction line and is equipped at its other end with a ventilation or gassing valve. <IMAGE>
