Title: Sealing, pipe-connecting, plug-in system
Inventor: MAYER HERBERT
IPC: F16L37/091
Filed: 1983-06-21
Abstract: The invention relates to a sealing, pipe-connecting, plug-in system for fluid or gaseous media. It creates a plug-in, firm, sealed, force-fitting and, if required, detachable pipe connection which saves energy, aids and assembly time. This is achieved according to the invention in that the pipe end which is to be connected is pressed as far as the stop into the connecting part which is equipped with a seal and a securing device, the securing device being widened by means of inclined points, and holding and locking the pipe with its internal diameter, which is constructed as a wedge, in such a manner that, in the event of an axial tension load, the securing device which is like a claw in the pipe wedges between the groove diameter of the connecting part and the pipe. The connection is released by widening the securing device using a special tool. The drawing (Fig. 2) shows an exemplary embodiment of the invention. The advantages to be achieved are a rapid, firm, sealed, reliable and, if required, detachable plug-in pipe connection by means of which individual influences on the sealing and torsional stress are considerably reduced, and assembly time and test time are saved. <IMAGE>

Patent DE-3422090-A1 (DE)
Title: Hydrodynamic pump
Inventor: DWORAK WILHELM
IPC: F04D5/00
Filed: 1984-06-14
Abstract: The hydrodynamic pump comprises a circular-cylindrical rotor (16) which runs with play in an approximately circular-cylindrical ring bearing (18). Formed in the ring bearing (18) are two continuous grooves (27, 28) diametrically opposite one another and running in an axial direction, through which grooves, together with a compression spring (32) acting on the ring bearing, the latter acquires an oval shape. As a result, suction chambers (33, 34) and discharge chambers (35, 36) are formed. As the rotor rotates, pressure medium is drawn in from an inlet (24) and by means of adhesion, similar to the situation in a hydrodynamic sliding bearing, is conveyed at the outer perimeter of the rotor from the suction chambers to the discharge chambers and from there, via grooves (19, 19') and radial bores (20) is conveyed to the outlet. The pump is of very simple construction and is suitable for very high rotational speeds at relatively low pressures and delivery rates. <IMAGE>
Patent DE-3423323-A1 (DE)
Title: Method and installation for obtaining and storing influencing currents
Inventor: SIEFERT PETER
IPC: H02N11/00
Filed: 1984-06-23
Abstract: It is known for the electrical scalar potential of the free ions in the room to be drawn away with the aid of plate capacitors and to be converted into useful energy by storage. Using the present arrangement, this effect can be considerably enhanced over that which was previously possible using relatively simple, partially conventional means. For this purpose, charged ions in accumulator batteries constructed as capacitors are caused to oscillate at their spatial frequency by pulses and are supplied with further potential, with the activating potential being regulated, so that electrical energy is released and can be extracted when the system is running. This discharging and reconstruction of the field are controlled in a predetermined time cycle. The accumulator batteries are electrically coupled overlapping the circuit. A capacitor or a kinetic energy store can be provided in order to buffer-store energy in a bridging manner. The meanings of the symbols in the drawing are:     W = resistors   c1, c2, c3, c4 = contactor switches   b1, b2 = batteries   E = extraction   <IMAGE>

Title: Method for determining the fluidised-bed height in furnaces
Inventor: HOELTER HEINZ DIPL ING
IPC: B01J8/24
Filed: 1985-05-09
Abstract: It is known to provide fluidised-bed installations with downstream filters and to return the precipitated filter dust to the combustion chamber in order to maintain the required fluidised bed and to return the still unburnt ash-like residues into the furnace so as to achieve as high as possible a degree of combustion. In order to keep as high as necessary the fluidised-bed height in a fluidised-bed boiler fired with fossil fuels it is proposed, according to the invention, to suspend filter cartridges (2) in the, or touching the, boiler stack, which have filter surfaces facing the flow direction and open only on one side and which return their filter surface cakes after dedusting directly into the combustion chamber without additional conveying processes, the fluidised-bed height being determined solely by the discharge of the ash from the combustion chamber. The filter cartridges (2) are designed so as to have reinforcements which preferably at the same time have a catalytic effect for the purpose of reducing NOx. <IMAGE>
