Title: Process and apparatus for cleaning filters in sewage treatment plants
Inventor: NYHUIS GEERT DR ING
IPC: B01D33/00
Filed: 1986-08-20
Abstract: The patent application relates to a process for cleaning the filter surface of filters in plants for the mechanical/biological purification of waste water (effluent), the inside of the filter being impinged with compressed air. According to the invention it is provided that the compressed air is fed to the filter surface in such a manner that small amounts of filtered waste water are entrained. An apparatus for carrying out the process is also specified. An essential advantage is the fact that a by a simple measure and thus simple apparatuses and little consumption of wash water, effective cleaning of the filter surface of filters in plants for the mechanical/biological purification of waste water is possible. This applies especially to the interior of the filter, from which interfering growth must be removed from time to time.

Title: Hand tool having an electric motor
Inventor: SCHUSTER HERMANN
IPC: H02K3/24
Filed: 1986-12-19
Abstract: The hand tool has an electric motor whose stator consists of a laminated core (5) and field windings (6), the winding overhangs (6a) projecting beyond the laminated core (5).

Title: Method for the thermostatically controlled matching of the heat output of a thermal radiator, as well as device for carrying out the method
Inventor: GEITNER MANFRED
IPC: F23N1/04
Filed: 1987-06-26

Title: Circuit arrangement for fixing the black level of colour signals in a colour television set
Inventor: MEUNIER THIERRY
IPC: H04N9/72
Filed: 1987-09-30
Abstract: In colour television sets which are suitable, for example, for teletext and satellite reception, the black levels of the individual colour signals have to be fixed to a constant value in order to avoid disturbing colour tinges on the screen. The black levels of a number of colour signals (1, 2, 3, 4) of the same chromaticity are fixed to a constant value according to a predeterminable sequence during line flyback. In this process, one colour signal (1, 2, 3, 4) at a time during a line flyback is fed via a switching network (U1, U2, U3), which is driven by a logic circuit (L), to the input of a comparator (V), at the second input of which there is a reference voltage (UR). The output of the comparator (V) is connected to the input of a multiplexer (M1). One output of the multiplexer (M1) is in each case connected to one input of the switching network (U1, U2, U3). <IMAGE>

IPC: B29C43/18
Filed: 1987-10-27
Abstract: The invention relates to a chamber filter disc or membrane filter disc of plastic, consisting of a thick-walled edge and a thinner central region, and to a process for producing finished mouldings, serving as chamber filter discs and membrane filter discs, of plastic with regions of the cross-section having variable thickness, specifically an edge which is considerably thicker than the central region of the disc, by laying at least one prefabricated solid plastic part into a mould comprising an upper part and a lower part and then filling further plastic material into the mould and subsequently pressing with the supply of heat before the mould is cooled and the finished moulding is removed from the mould. The object of the invention is to provide a chamber filter disc and membrane filter disc which can be produced simply and quickly and is free of voids and cracks and does not cause any problems in particular in the transition region from the central thin region of the disc to the thick-walled edge. The process according to the invention consists in using as prefabricated part an annular solid core which is inserted such that, in the pressed-down state, it has the same distance from all the inner walls of the mould and in that the further plastic material is filled into the mould as melt.

Patent DE-3740669-A1 (DE)
Inventor: STOLL KURT
IPC: F16F9/02
Filed: 1987-12-01
Abstract: The invention proposes a pneumatic shock absorber with a piston (10) displaceable in a cylinder (11) and having a piston rod (14) which projects from the latter. Via a non-return valve (25) which forms an inlet, a pressure space (12) situated in the cylinder (11) and bounded by the piston (10) is connected to an external pressure source (P). An outlet valve (19) which releases the compressed air during a damping movement of the piston has a valve piston (41) which is guided in a sealed manner in a valve chamber (29) and divides the latter into two sub-chambers (32, 33). The first sub-chamber (32) connects a passage (20) leading to the pressure space (12) to an outlet passage (35), the connection being interruptable by means of a valve seat which can be closed by an end face of the valve piston (41) subjected at least in part to the pressure of the pressure space (12). The second sub-chamber (33) is connected to the pressure space (12) or to the pressure source (P). Finally, a spring (39) which presses the valve piston (41) against the valve seat (36) is provided. As a result, no pressure losses occur in either of the two stop positions, the piston returns automatically to the first stop position in the unloaded condition and the damping performance during the damping process is very uniform and continuous. <IMAGE>

Title: Firing system for pistols and rifles
Inventor: CLAUS WILFRIED
IPC: F41B7/02
Filed: 1988-02-04
Abstract: The system uses the cocking force and dynamics of the rubber for private sporting firing applications. The basic structure models a pistol, a Colt or rifle. One or more pieces of rubber (rubber bands) are stretched over said structure, parallel to the barrel, and are held by a rigid holder at the front and by a tilting holder, which can be locked, at the rear. If all the holders are tensioned, the pieces of rubber can be fired individually and successively at the target, via a sight. The trigger lever is operated for this purpose, releasing the tilting holder directly and at the same time locking the next tilting holder. The system is safe and interesting to handle. <IMAGE>

Title: Method and apparatus for filling a container of a concrete mixer
Inventor: HUDELMAIER GERHARD DR
IPC: B28C7/06
Filed: 1988-04-20
Abstract: It is known to fill concrete mixers with the concrete components in layers so that the said concrete components can be intermediately stored overnight. This has, however, hitherto been possible only in the case of concrete mixers having integral vibrators. As a result of the novel method and the novel apparatus, it is, in contrast, possible, by using a container-independent vibrator, to achieve the same effect, the said vibrator, when a filling apparatus is used, being assigned to the filling hose of the said filling apparatus. The novel method and the novel apparatus are suitable in particular for filling drums of mobile concrete mixers.
