Patent DE-3636479-A1 (DE)
Inventor: BECKER NORBERT
IPC: B22C5/18
Filed: 1986-10-27
Abstract: In order to rationalize the operation of foundries and to avoid environmental stresses, it is endeavored so to rework used molding sand accruing as black sand and to free it from binder residue, so that this sand can be used without restriction like new sand. To achieve this aim through thermo-mechanical regeneration the black sand is heated in predetermined, relative low height layer in a fluidized bed furnace to a temperature exceeding 500 DEG  C., preferably 750 DEG  C. Through the swirling motions of the heated black sand, preferably supported through strong vibrations of the supporting base, the thermal destruction of the enveloping binder particles and a mechanical liberation of the sand grains form their enveloping binder remains is achieved. By means of a forced throughout (e.g. through appropriate vibrations or by means of a scraper conveyor) a uniform throughput with constant layer height is achieved which can be stabilized by means of additionally installed webs so that the desired mode of operation is ensured. By means of pre and post-treatment heat exchangers, the energy requirement can be kept low, while an appropriately high combustion temperature ensures at the same time the creation of environmentally safe oxidation products.

Title: Process and apparatus for reducing and spatially restricting exhalations of volatile substances from fluid media
Inventor: STAHN ROLF
IPC: E03F7/00
Filed: 1987-01-07
Abstract: Where water management of residential areas is concerned, sewage is transported which contains volatile substances which can cause strong odours and material corrosion in the sewer system. A particular departure point for these phenomena is constituted by water turbulence, such as that which occurs at falls and openings of pressure pipelines. In order to prevent or to reduce gas exhalations spreading into the sewer system at such operating points, it is proposed to set up exhalation spaces through which flow passes and which are isolated from the sewer air spaces.

Title: Method of fault location in digital circuits with a bus structure
Inventor: WOESTENKUEHLER GERD DIPL ING
IPC: G06F11/22
Filed: 1987-03-16
Abstract: The invention concerns a method of fault location in digital circuits with a bus structure, in which the signal states are detected and evaluated at individual circuit points. To carry out a simple evaluation in digital circuits with bidirectional and/or multiplexed lines (1, 2, 3, 4, 5), different reception time periods, to each of which individual clock signals are assigned, are defined for fault path tracking. The physical nodes in the data streams are divided into logical nodes, and the logical nodes are assigned to defined functions, which are carried out via the lines. The fault is located using the dependence of the logical nodes. The invention is mainly used in test procedures for microprocessor circuits. <IMAGE>

Title: Method of control input, computer processing and display
Inventor: CORDELL STEVE DIPL ING
IPC: G06F3/0489
Filed: 1987-04-06
Abstract: Manual operation of an input device and the desired effect on a display are closely related to each other. To control a display or similar peripheral efficiently, quickly and precisely, the input elements must be adapted to the target user group. Physically handicapped people, or people who are not handicapped but must know the effects of their input decisions immediately (e.g. fighter pilots), can enter their commands using a simple, (preferably) piezo-electric film key. If this key is connected to a control computer and a display, commands, which can be quickly learned, can be entered, converted via an algorithm and the immediate past history, and shown on a display. There are two kinds of input commands: those which cause display movements, and those which represent a decision command. The execution times of the first command type preferably depend on the user, and are therefore not linked to a pre-programmed time. This capability gives a fighter pilot, for example, the ability to enter his commands without having to wait until the desired event occurs. Using the same key with which the user entered his display movement commands, the decision commands can be entered. The speed of pressing and pressure on the key are interpreted by the control computer using algorithms. An input signal, which is generated by ... Original abstract incomplete.

Patent DE-3713473-A1 (DE)
Title: Liquid-free electrophoresis
Inventor: PAAS-LINK ANDREAS DR
IPC: G01N35/00
Filed: 1987-04-22
Abstract: For the qualitative expansion and improvement of electrophoresis, the mixtures, cells or cell organelles to be separated are not separated in solutions, but are exposed to an electric field in the liquid-free state as monomolecular dusts. These dusts are transported via a continuous gas stream in an electric field applied perpendicularly thereto and separate in accordance with the charge on the different constituents of the dust. The process offers particular advantages under weightless conditions, since thermally caused inteference of the uniform gas stream is then prevented. The dusts to be separated are transported to and from the separation chamber via gas-permeable transport membranes.
Patent DE-3721090-A1 (DE)
Title: Pneumatic stowing line with simplified rotary drive discharge
Inventor: PAWELSKI LUDWIG
IPC: E21F15/08
Filed: 1987-06-26
Abstract: A rotary drive discharge of favourable overall dimensions on pneumatic stowing lines is guided close to the face support and has an end discharge. It has only a small stowing cavity. The pneumatic stowing line can thus be reliably guided even in thin seams, for example on the floor. The swivel device designed as a rotary drive runs axially parallel to the pneumatic stowing line and has guide and holding arms which are connected to one another in such a way that they cannot be displaced or cannot be rotated in the hydraulically locked state and which have on the inside in the area of the rotary drive a thread which corresponds with the hydraulically displaceable, one-piece threaded guide shaft. When the threaded guide shaft or the hydraulic cylinders arranged at the end are acted upon, the coupling point quickly opens or closes. Here, the coupling point is protected by a sealing sleeve which is connected in a control circuit to the rotary drive. Attached to the pneumatic-pipe sections are stowage supporting walls which do not require separate drives and ensure that a favourable slope is produced and maintained. <IMAGE>

Title: Additional device for scissors or a scissor-like arrangement
Inventor: ULLMANN MICHAEL
IPC: B26B13/00
Filed: 1987-06-27
Abstract: Scissors are designed either for right-handed or left-handed operation. Malfunctions can occur when the scissors are not used as intended, owing to a separation of the cutting edges of the scissors. The additional device is intended to make it possible for right-handed scissors also to be used without difficulty in the left hand and vice versa. The additional device is characterised in that it is constituted by a shaped part (1; 1') which takes the form of a two-armed lever and is made of wire, one end (2; 2') of which shaped part takes the form of a gripping eye (4; 4') to permit insertion of one or more fingers (5) of the hand operating the scissors (6; 7) and the other end (3; 3') of which takes the form of a pressing arm (8; 8') which extends transversely to the cutting bars (61, 62; 71, 72) and is guided through between the latter and for which the cutting bar (61; 71) adjacent to the gripping eye (4; 4') acts as a pivot axis. This device is very uncomplicated, but also effective, as it transmits the pressure generated by the finger of the "wrong" operating hand via the pressing arm as a moment to the cutting bars and presses the two edges against one another. The additional device is suitable for all scissors which are intended for both right-handed and left-handed use. <IMAGE>

Title: Instrument (test set) for calibration and adjustment of laser rangefinders
Inventor: SIEBENECK HEINRICH-JOACHIM DR
IPC: G02B27/34
Filed: 1987-09-11
Abstract: A universal, integral instrument is proposed for calibration and adjustment of laser rangefinders, using which all conventional laser rangefinders can be calibrated, checked and adjusted irrespective of the wavelength of their laser and the distances between the outlet pupils of the transmitter and receiver. To this end, in addition to an adjustable autocollimator which emits modulated light, a slanting reflector is provided at whose focus a target mark is arranged. The receiver aperture of the laser rangefinder is illuminated via the slanting reflector. The illumination light is modulated and has the same wavelength as that of the laser of the laser rangefinder. The field of view of the receiver aperture and the laser pulse of the laser transmitter are imaged on a pyrikon. The image of the point source of the autocollimator on the pyrikon is used as a reference mark. The images are stored in the image memory of the pyrikon and are fed to a computer for automatic evaluation.

Title: Production of pig iron by reduction of finely granular iron ore by means of carbon carriers and oxygen carriers, and plant for carrying out the process
Inventor: BARIN IHSAN PROF DR
IPC: C21B13/14
Filed: 1987-11-20
Abstract: The invention relates to a process for the continuous production of pig iron by the reduction of finely granular iron ore by means of carbon/oxygen carriers, the finely granular iron ores being preheated and prereduced by means of hot reduction gas in a heat exchanger system, without sticky or liquid phases being formed. The products thus formed are subjected to end reduction in an iron bath and converted into liquid pig iron. In the process, there is produced in the iron bath, by continuous supply of carbon carriers and oxygen carriers, carbonization of the pig iron and a gas essentially consisting of CO and H2. This gas is firstly used as hot reduction gas for preheating and prereducing the iron ore particles and, secondly, undergoes partial afterburning in the iron bath reactor in order to meet the energy requirement there.

Inventor: BUSSE OSWALD DR ING
IPC: B65G19/06
Filed: 1988-05-03
Abstract: Steep conveyors for bulk material usually have a horizontal ejection region. The bulk material is fed via a hopper. It often occurs that the bulk material slips back out of the steep conveyor strand and then forms a roll of material at the deflecting station. The blockages must be removed at high service cost. The two deflecting stations cause high chain wear. According to the invention, the steep conveyor (5) is formed in a straight line without deflecting stations, and feeding is implemented by a horizontal positive screw conveyor (3) which presses the material to be conveyed into the upper side (4) of the steep conveyor (5). <IMAGE>
Patent DE-3816351-A1 (DE)
Inventor: KOMOSSA WERNER
IPC: B60G17/08
Filed: 1988-05-13
Abstract: A shock absorber wherein a piston divides the internal space of a cylinder into two cylinder chambers and has a passage of variable cross-sectional area for the flow of damping fluid between the cylinder chambers. The piston has a first section which is connected with a piston rod and is in sliding engagement with the internal surface of the cylinder, and a second section which is reciprocable in the first section and has two sets of surfaces which are acted upon by damping fluid. The passage is defined by the two sections. One set of surfaces is acted upon by damping fluid which is pressurized as a result of axial movement of the piston in the cylinder, and the other set of surfaces is acted upon by damping fluid which fills a plenum chamber of the piston and is acted upon by a valving element forming part of an electrically operated fluid pressure regulating unit. The difference between the forces which the damping fluid applies to the two sets of surfaces determines the axial positions of the two sections of the piston with reference to each other and hence the cross-sectional area of the passage for the flow of damping fluid between the cylinder chambers.
