Patent DE-3417816-A1 (DE)
Title: Programmable switching network
Inventor: GRENZEBACH KURT ING GRAD
IPC: G11C17/14
Filed: 1984-05-14
Abstract: The programmable switching network serves to generate pre-defined strings of binary signals. In a memory, in particular a read-only memory, data words assigned to the instantaneous values of the binary signals are stored which are read out from the memory in temporal succession depending on address words present at address inputs of the memory. At least one control character is assigned to each data word which is read out simultaneously with the data word. If the control characters have a first binary value, the addresses are scrolled step-by-step. If the control characters assume a second binary value, the address is set to a pre-defined value. Automatic control of the switching network is achieved in this way. <IMAGE>

Title: Player for disc recordings
Inventor: WINE CHARLES MARTIN
IPC: G11B9/06
Filed: 1984-05-30
Abstract: To form an interactive disc system, the information corresponding to a first program content is recorded together with the information corresponding to a second program content on a recording disc (12) which has a single spiral track. If an interactive part of the disc is played, the associated disc player (10) receives two sub-items of information, so that it plays the desired information in each case. One sub-item of information is specified by the user, who chooses the program to be reproduced (31). The other sub-item of information (26) is recorded on the disc and tells the disc player where the program being scanned (picked up) at that instant is and to where the scanning (pick up) transducer (35) is to be moved in order to arrive at the desired program. In the case of a particular embodiment, the spiral track is designed as a groove which is located in the surface of the disc and in which a scanning (pick-up) needle engages. According to a development of the invention, the first program content is recorded in interleaved form with the second program content.

Title: Method for testing a component for leaks
Inventor: BUERGER HEINZ DIETER
IPC: G01M3/22
Filed: 1984-07-19
Abstract: The invention relates to a method for testing a component for leaks, in particular a closed container which is subjected on one side of the wall to a pressure and on the other side of the wall to a fine vacuum whose deterioration provides a measure for a leak. According to the invention, there is applied to the pressure side a test liquid which evaporates upon passing through a leak and impairs the pressure on the vacuum side substantially more clearly than could a test gas. Water and liquid gases can in particular be used as as test liquid. The testing for leaks can be linked to impregnation of the component by adding to the test liquid a solid in dissolved form which solidifies in the leak channels. <IMAGE>

Patent DE-3439070-A1 (DE)
Title: Process and equipment for the continuous production of crude iron and energy-bearing hot gas from fine-grained iron ores and carbon carriers
Inventor: WEIGEL HORST
IPC: C21B13/14
Filed: 1984-10-25
Abstract: The invention relates to a process and equipment for the continuous production of crude iron and energy-bearing hot gas from fine-grained iron ores and carbon carriers. In known processes, sticking problems and undesired soot formation occur during the reduction of the fine-grained iron ores. Cooling of the hot gas has also hitherto caused difficulties and high equipment investment costs. These problems and difficulties are overcome by the invention in such a way that the energy-bearing hot gas generated in a smelting reactor 1 is used in a coal heat exchanger system 12 for the coking of coal and is thereby cooled and then utilised in a two-stage reducing unit 2, which consists of a co-current pneumatic reactor 22 in the first reduction stage and of a fluidised-bed reactor 23 in the second reduction stage, for reducing the fine-grained iron ores. The sticking of the reduced iron ore particles during the reduction is here eliminated by the addition of coal and/or limestone as a separating agent to the reduction unit 2. <IMAGE>

Title: Arrangement for supplying an electrical load by means of an invertor
Inventor: THOMAS FRIEDRICH-WERNER DR ING
IPC: H02M7/527
Filed: 1984-11-09
Abstract: An arrangement for supplying an electrical load (13) by means of an invertor (9) which is fitted with turn-off thyristors (21, 22, 23 and 24). The inductor (13) is supplemented by a capacitor (15), which is connected in parallel with respect to the invertor (9), to form a tuned circuit. Its design frequency corresponds essentially to the output frequency of the invertor (9). In consequence it is possible to operate the turn-off thyristors (gate turn-off thyristors) at the full turn-off power at considerably higher frequencies than is possible without the presence of a tuned circuit which is formed from the inductor (13) and the capacitor (15). <IMAGE>

A very high degree of pneumatic conveying efficiency is achieved by these means, with an especially simple design.
Patent DE-3529161-A1 (DE)
Title: Circuit arrangement for telecommunications systems, in particular telephone switching systems, with information-polling devices cyclically activating answering stations
Inventor: JANS HERBERT DR ING
IPC: H04Q3/72
Filed: 1985-08-14
Abstract: A polling device cyclically retrieving information from different answering stations controls the different answering stations with differing regularity, for which purpose addresses of the answering stations are stored in a polling memory with differing regularity. If a polling device has received no information when polling an answering station, it is bypassed on one of the next occasions. A note bit is stored for this purpose in the polling control memory under the address which has just been polled. If the same position in the polling memory is again reached after a polling cycle, the note bit causes the address not to be read and the answering station to be bypassed once instead; the note bit is again deleted. <IMAGE>
Patent DE-3530143-A1 (DE)
Title: Watering and heating device
Inventor: TIEDT UWE DIPL ING
IPC: A01G25/02
Filed: 1985-08-23
Abstract: Watering and heating device which can be used as a watering and heating line. Instead of the previous two separate parallel pipe systems, in each case one for the watering and one for the heating, only one line system is required. Depending upon the inner pressure of the line, an internal diaphragm either frees the water outlet from the outlet openings of the pipe or hose or closes it. Thus, the two functions as watering and heating line become possible in one pipe. When the outflow is closed, hot water is sent through the line (heating line), and when the outflow is open, after switching over to the watering circuit, water can emerge (watering line).

Title: Method of adjusting a hearing-aid, a hearing-aid, and the use of it
Inventor: BERGENSTOFF HANS
IPC: H04R25/00
Filed: 1985-12-02
Abstract: A hearing-aid for partially deaf people with hearing losses at high frequencies contains a sound input opening with a sound detector (1), an adjustable amplifier circuit (2, 3, 4), and a sound reproduction device (5). The control part (3) of the amplifier circuit has at least one control element (P1), which is operated by the user, who is thus able to change the steepness of the frequency response of the amplifier at frequencies above a limit frequency, so that an alterable boosting of high frequencies is achieved. The hearing-aid can also have a second control element (P2) which is an essentially frequency-independent control element for the basic amplification which is set by a hearing specialist on the basis of data about the user, including audiograms. The invention also concerns a method and the use of the hearing-aid to compensate for hearing losses at high frequencies. The achieved result is that a partially deaf person with hearing losses at high frequencies can readjust the hearing-aid in small steps, so that the usual transitional problems are avoided, and it is thus made easier for the user to become accustomed to the use of the hearing-aid. <IMAGE>

Title: Fireproof and radiation-proof wall and/or floor lead-through
Inventor: HANK DORIN DIPL ING
IPC: F16L5/04
Filed: 1986-02-27
Abstract: In order to form a fireproof and radiation-proof wall lead-through, both the inner opening, which is directed towards the so-called hot side in the primary region of a power station, and the outer opening are closed off by a Brattberg frame (20, 24). The interior of the wall lead-through (13) is filled with a granulate consisting of barium sulphate. In order that the granulate can be easily introduced there is located, on the upper profile portion of the profile frame (22) bearing the outer Brattberg frame (24), a feeding tube (26) which passes at an acute angle through the outer surface of the concrete wall (10) and, on its inner region, is welded to the profile frame. Consequently, a fireproofing mortar layer located on the outer side is dispensed with and the subsequent installation of cables is simplified considerably in this manner. <IMAGE>
Patent DE-3607736-A1 (DE)
Title: Shut-off valve
Inventor: NEMETZ JOSEF
IPC: F16K1/226
Filed: 1986-03-08
Abstract: In the case of shut-off valves which exhibit a spring bridge for restoring a seal lining which has only a low degree of flexibility, if any at all, and consists, for example, of a fluoroplastic, the spring bridge is arranged in each case such that it rests as a separate element on the seal lining. As a result, a distortion and thus deformation of the seal lining can arise during the closure procedure, in particular in the case of relatively high operating temperatures. Disruptions in functioning can thus result. This disadvantage is eliminated in that the seal lining is equipped with, i.e. fixedly connected to, the spring bridge. Seal lining and spring bridge thus form a unit.

Title: Method of constructing excavation pits or hollow spaces
Inventor: GUDEHUS GERD DR
IPC: E02D19/14
Filed: 1986-03-21
Abstract: In a method of constructing excavation pits or hollow spaces in water-bearing soils and/or soils of low strength, freezing pipes are driven into the soil from shafts which are provided along the axis of the excavation pit to be constructed or the hollow space to be constructed. The freezing pipes start from the shaft in a radial direction. These freezing pipes are driven into the soil surrounding the shaft at an oblique angle to the vertical, for example at an obtuse or acute angle to the vertical, or even at a largely right angle to the vertical. These freezing pipes, with freezing pipes driven essentially vertically into the soil and provided in the area of enclosure walls to be formed, produce such a form that, after the feeding with freezing agent and the freezing of the soil in the area of the freezing pipes, a supporting body is formed in which the freezing pipes starting from the shaft establish a plane load-bearing structure. In a preferred embodiment, freezing pipes running in the radial direction from the shafts at various levels can be provided so that the ice wall, through the group of freezing pipes lying right at the bottom, is also stabilised from below for absorbing earth and water pressure. The method according to the invention can likewise be used for constructing vertical areas, in which freezing pipes, starting from the vertical shafts and lying in a vertical plane, ...
