Patent DE-3228175-A1 (DE)
Title: Roller for supporting and guiding a continuously cast metal strand from a continuous metal casting plant
Inventor: ENGEL KURT ING
IPC: B22D11/128
Filed: 1982-07-28
Abstract: The roller has one or more roller bodies (4) which come into contact with the strand surface, are assembled from a plurality of parts (6,7), and are rotatably mounted on the stationary shaft by means of roller bearings (5), the roller body or bodies (4) being formed from at least three sleeves (6,7) which are arranged mutually aligned, connected together, and having the same external diameter, to be precise from two end sleeves (6) and at least one middle sleeve (7) lying between them. In order to be able to select the roller diameter to be as small as possible, so that the shafts of adjacent rollers can be moved as closely together as possible, the end sleeves (6) are formed as the outer bearing rings of the roller bearings (5) provided between the roller body (4) and the stationary shaft (1). <IMAGE>

Title: Process for generating gas and steam via an optionally provided upstream gas generator with a downstream combustion device which optionally can also be used as a heat exchange device
Inventor: HOELTER HEINZ DIPL ING
IPC: C10B53/00
Filed: 1982-09-02
Abstract: To generate gas and steam, a coal/refuse mixture or else only a refuse mixture is outgassed in an overfeed grate outgasser, the resulting gas is purified and the hot coke is either burnt directly or else cooled by heat exchange, discharged and stored. The heat recovered by the combustion of the coke or by the heat exchange is used for steam generation or for other energy-utilising purposes. A continuous operation is always ensured at all times, since the equipment for carrying out the process has an additional feed facility, through which coke can be fed if required. <IMAGE>

Title: Method and device for regulating the discharge of through-flow tanks
Inventor: STAHN ROLF
IPC: E03F5/10
Filed: 1982-09-10
Abstract: The known communal combined sewage systems have a design fault from the point of view of engineering and economics. This fault consists in that, in the event of rain, all areas connected to the system, such as roads, properties, buildings, conduct the rainwater without delay into the drainage channels. As a result of this, all drainage conduits and additional sewage installations have to be dimensioned for load peaks. To remedy this, the use of the above-described through-flow tank with simultaneous storage of water is proposed. This tank, referred to as a retaining trunk, can be arranged downstream of all areas to be drained. The retaining trunk is designed such that, when water flows in, it simultaneously delivers a small proportion to a drainage conduit, stores the remaining water flowing in and allows this to drain off with a delay when the influx has ended. A smaller rainfall occurence in each case is thereby simulated for the drainage conduit. The device for the delayed discharge acts automatically, as a function of the water level. It is obvious that these retaining chambers, which are above-ground or close to the surface, can be manufactured, especially mass-produced, more cheaply than similar deep, underground sewage chambers.

Title: Shopping trolley
Inventor: WANZL RUDOLF
IPC: B62B3/14
Filed: 1982-09-28
Abstract: Shopping trolleys which can be pushed one inside the other have at their rear basket end a folding basket section which can be pivoted into the inside of the basket. These folding basket sections tend to clatter when moving shopping trolleys over uneven ground or in the train configuration. The invention proposes a shopping trolley (1) whose folding basket section (7) has in its lower region (8), preferably at the two corners (9), shock absorbers (13) which are attached in such a way that they rest against the basket (3) of the shopping trolley (1) when the folding basket section (7) is located in the position of rest and their distance from one another is kept such that they rest on the edge (4) of the upper side wall of that basket (3) of a shopping trolley (1) which is pushed from backwards into the aforesaid shopping trolley (1) for the purpose of forming a train. The shock absorbers (13) prevent the folding basket section (7) from clattering both when an individual shopping trolley (1) is being pushed and also when a train of several shopping trolleys (1) is being moved. <IMAGE>
Patent DE-3236954-A1 (DE)
Title: Electrical machine, to be precise a heat producer, heat generator
Inventor: CRULL SIEGFRIED
IPC: H02K49/04
Filed: 1982-10-06
Abstract: The invention relates to an electrical machine, to be precise a heat generator, having a stator (1) fitted with electromagnets (23) and a rotor (3), arranged in the stator (1), whose rotor poles (13, 21) act by means of their external magnetic field force on the iron (25) and the induction conductors (27) in the stator (1). The electromagnets (23) of the stator (1) are grouped around the rotor (3). In the space inside the stator electromagnet (23), the rotor (3) consists of one or more magnetic (especially permanently magnetic) columns (7) which are alternately magnetised or poled in opposite directions. Placed on the axial pole surfaces (11) of the rotor magnetic columns (7) are pole shoes (13) which, together with rotor arms (15), extend so far radially outwards that they overlap the axial pole surfaces (29) of the stator electromagnets. When the rotor (3) rotates, a three-dimensional magnetic flux passes over the coils (27) of the electromagnet (23) periodically, which leads to voltage induction in the coils (27) and the generation of heat, particularly in the iron of the stator (1). <IMAGE>

Patent DE-3241375-A1 (DE)
Title: Method for projecting images and device for carrying out the method
Inventor: HELLER GUENTER
IPC: G03B41/10
Filed: 1982-11-09
Abstract: In the known image reproduction devices, in particular film projectors, the film is held between deflecting toothed wheels of a gripper device, which engages in the perforations of the film, for 1/16 s, or also other periods in each case. In the time in which the film is held, the light beam is interrupted three times by means of a rotary disc shutter, so that the viewer sees the image 48 times within a second. The rotary disc shutter causes considerable noise, and the film is very easily damaged by the gripper system. In order to avoid the noise of the rotary disc shutter and to avoid damage by the gripper system, the invention provides for the light beam on the side of the film averted from the light source to be deflected onto the screen or the like by a mirror which can be pivoted about an axis, can track the film, and can be repivoted.

Title: Ink jet printing mechanism for office machines
Inventor: FRERICHS KLAUS-DIETER ING GRAD
IPC: B41J2/175
Filed: 1982-12-22
Abstract: In ink jet printing mechanisms it is necessary to feed ink continuously to the print head (9) and to indicate that the ink supply container (49) is becoming empty at an early stage by means of an ink empty display. In order that this disposable ink supply container (49) is not too expensive, the ink empty display is arranged on an intermediate ink container (11) which is movable with the carriage. The supply of ink from the supply container (49) to the intermediate container (11) takes place via a pump, e.g. via a hose pump (43) which interacts with the conveying hose (51). If the ink supply container (49) becomes empty during the pumping operation, the hose pump (43) generates a negative pressure in the conveying hose (51) due to its power of deformation. By means of this negative pressure, harmful air would enter through the hose (51) into the system by diffusion if the conveying hose (51) was not connected to the pressure compensating container (47) according to the invention. The pressure compensating container (47) prevents diffusion of air into the ink supply system and thus always guarantees a constant good printing quality. <IMAGE>

Title: Method and digital triggering equipment for producing the triggering pulses of a pulse-controlled invertor
Inventor: BRAUN RUEDIGER DIPL ING
IPC: H02M7/529
Filed: 1983-05-09
Abstract: A basic pulse pattern, which is independent of the saturation level, is stored in a storage circuit which is driven by a drive signal (Z). The drive signal (Z) is formed from a desired displacement value ( alpha ), which is dependent on the saturation level, in a displacement device (11.R) by addition and/or buffer-storing of a propagation-time signal (N) which produces [sic] a counter (13) which is driven by an oscillator (12). A read-only memory (14.1 to 14.4) determines for each saturation level a plurality of desired displacement values ( alpha 1 to  alpha 4) associated with different angle regions of the propagation-time signal, by means of which values a multiplexer (18.R), which is driven by an angle-region discriminator (17.R), in each case switches the desired displacement value ( alpha ) associated with the current phase angle of the propagation-time signal to the displacement device (11.R). <IMAGE>

Title: Method and device for oscillation-damped control or regulation of a converter-supplied asynchronous machine
Inventor: RENG LEONHARD DIPL ING
IPC: H02P21/08
Filed: 1983-06-27
Abstract: An asynchronous machine (1) is supplied via a converter (2) whose output amplitude is controlled corresponding to the magnitude of a desired current vector which is determined by a desired slip-frequency value <IMAGE> and a desired magnetisation current value (i psi 1*). The frequency is controlled as a function of the measured rotor rotation speed <IMAGE> corresponding to the rotation speed of the desired vector. In order in this case to damp out oscillations which occur primarily at load angles above 45 DEG , an additional variable is added to the frequency desired value such that, at load angles above 45 DEG , a change in the slip-frequency desired value temporarily causes a change in the converter frequency which opposes the frequency change caused by the change in the desired value. At least at load angles above 45 DEG , the additional variable is selected to be approximately proportional to the negative change in the desired slip-frequency value. <IMAGE>

Patent DE-3337392-A1 (DE)
Inventor: BRUNS MICHAEL DIPL ING
IPC: B61L23/00
Filed: 1983-10-14
Abstract: In order to control and supervise transport arrangements with several track transport vehicles on a common track divided up into sections, track areas are reserved at certain times for the exclusive use of particular transport vehicles. The execution of a transport is transmitted to a transport vehicle in the "waiting" state, an area of associated track sections required for the execution of the transport being reserved for this transport vehicle (Figure 1). A precondition for the transmission of the transport order is that the required track area can be reserved. The reservation is cancelled again after the termination of the transport. If two or more adjacent transport vehicles cannot carry out any further transports since they are mutually blocking the required track areas, these transport vehicles, with the exception of one, are moved so far that the track area required for the execution of a transport becomes free for this one vehicle.
