Patent DE-4321093-A1 (DE)
Title: Soiled water cleaning - has a sieve filling chamber at basin to trap solid concrete residue for removal and recovery by a screw conveyor
Inventor: BRENNER HORST
IPC: B01D36/04
Filed: 1993-06-25
Abstract: The assembly to clean soiled water has a filling chamber (38) within the soiled water basin (12), held over the level of the water (16). The walls and/or base (32) of the filling chamber have sieve passage openings where soilds cannot pass through. The filling chamber (38) has max. 20% of the soiled water basin (12) capacity, and can be located outside the basin. A water level monitor (20) ensures that the recirculation unit (22) is always below the water level (14) and covered by water (16), for the strring (22) action. A conveyor (30) extends into the filling chamber (38) to carry out the trapped solids, as an integral part of the chamber (38), or a separate units inserted into the water basin (12) and carry the stirrer (22) and basin cover and the water level control (20). USE/ADVANTAGE - The assembly is for users of concrete, where the concrete residue and its components are contained for recovery without entering the waste water disposal system. The sytem gives an effective recovery of the concrete residue, and a water cleaning action where very little matter is allowed to escape into the water outlet.
Patent DE-4322608-A1 (DE)
Title: Device for power modulation during plasma excitation, preferably during use of gas lasers
Inventor: RETTICH THOMAS DR ING
IPC: H01S3/0975
Filed: 1993-07-07
Abstract: The device has electrodes for coupling power into the plasma, which electrodes are connected to a voltage source. Because of the high costs of radio-frequency transmitters, further plasma applications and the use of CO2 lasers are limited since, although the laser is an ideal tool for a large number of areas of use, it is, however, very expensive. In order that the device allows rapid power modulation but has an extremely cost-effective design using cost-effective components, the device has an output stage at whose output a square-wave output voltage is present which can be applied to at least one downstream tuned circuit at a frequency which is at least close to the resonant frequency. It is possible to produce a high-frequency high voltage by combining a fast-action power output stage operating in the switching mode with a high-frequency tuned circuit. Using the device, fast power modulation is possible, as in the case of a radio-frequency transmitter. The device is thus distinguished by fast-action power control and cost-effective design.

Title: Process for producing gas bubbles in water and also zeolite particles for carrying out the process
Inventor: KRUEGER REINHARD DIPL PHYS DR
IPC: F41H11/02
Filed: 1993-07-08
Abstract: Process for producing gas bubbles in water, in particular a gas bubble screen for defence against torpedoes, in which zeolite particles, in particular zeolite spheres, in which stored gas is stored are introduced into the water, whereupon the stored gas is desorbed from the zeolite particles to form bubbles, characterised in that the zeolite particles contain at least one zeolite from the group consisting of the types NaA, NaX, CaA and MgA; and in that the stored gas is selected depending on the crystal lattice structure of the zeolite in such a way that the molecular diameter in relation to the crystal lattice structure of the zeolite(s) ensures a maximum storage capacity, and also zeolite particles for carrying out this process.

Title: Medical ultrasonic diagnosis system - has ultrasonic converters arranged in specified direction in order to obtain tomographic images of inside of subject using ultrasonic waves which are transmitted from and received by probe
Inventor: MATSUSHIMA TETSUYA
IPC: G10K11/34
Filed: 1993-07-12
Abstract: A delay/adding unit delays corresp. reception signals and adds delayed signals, in order to produce an added signal, which gives a focus, which is shifted sequentially in the subject. A delay time control unit controls corresp. delay times of the reception signals in the delay/adding unit. An indicator unit indicates a tomographic image of the subject coinciding with the added signal which is given by the delay/adding unit. The delay time control unit controls the delay/adding unit, so that corresp. reception signals can be delayed adaptively at corresp. delay times. These times are specified for a number of ultrasonic converters in coincidence with a focus position. The focus position is shifted sequentially, corresp. to the array-positions of a number of the ultrasonic converters. Also for a time period from a point of time, the ultrasonic waves are transmitted by the ultrasonic converters. ADVANTAGE - Improves delay control. Facilitates forming of suitable position focal points even if scan aperture is enlarged. Can easily absorb irregularities of sonic speed and time lag, to ensure high resolution tomographic images.

Title: NAND-type volatile DRAM matrix - comprises MOSFET-capacitor cells and static storage register groups for temporarily storing data for re-writing-in or reading-out data from cells for each column of matrix
Inventor: HASEGAWA TAKEHIRO
IPC: G11C11/404
Filed: 1993-07-30
Abstract: The storage capacitors of the matrix cells are coupled to each MOSFET source. Register groups (40) for each memory cell temporarily store the signals stored in a single memory cell for each matrix column, read out data from each memory cell, or write the data into them. Pref. each memory cell has a NAND structure. Each register group typically has a static memory cell structure. At least a part of the register groups is used in common by several memory cell matrices. Additionally there are several address intermediate memory circuits, storing addresses for address bits of the memory cell matrix. ADVANTAGE - Reduced time for data read-out and rewriting, and reduced data access time.

Title: Inductive speed sensor
Inventor: RIMKE KERSTEN
IPC: G01D11/24
Filed: 1993-09-21
Abstract: An inductive speed sensor is proposed which essentially consists of a housing, an electric coil which is arranged in the housing and mounted on a moulded part, as well as of a pole core (pole body) and an assigned permanent magnet, which are arranged in a cutout (recess) of the moulded body. In order to obtain an inductive speed sensor for whose measuring arrangement it is possible to use a cost effective (economical) pole core, which does not place high demands on the accuracy of production, and an assigned magnet, and for which the calibration and the fixing of the pole core and magnet are performed without additional components, the rear housing section is formed by the other end region of the moulded part, and the cutout present in the moulded part is constructed as a blind hole. The permanent magnet and thus the pole core are held clamped in the blind hole against the base of the front housing section by means of a spring element located in said hole.

Title: Rotary (rotating) wing with aerodynamic or hydrodynamic drive and output (performance) control
Inventor: GUNDER HANS ERICH
IPC: F03D3/00
Filed: 1993-10-13
Abstract: The mode of operation of rotary wings depends on the ratio of the peripheral speed of the outermost profile piont to the speed of the incident flow. A rotary wing can be driven by motor. However, it is also possible to use a proportion of the energy of the medium flowing past to drive the rotary wings. The selection of the drive part determines in this case the rotational speed of the rotary wing, and a control of the drive part permits a change in the rotational speed to control the output of the entire wing. The entire wing can also be divided into a plurality of mutually independently rotating and controlled output sections having different drives.

Title: Process and solvent absorber device which can be regenerated and dried using air drawn from working space
Inventor: KOHLMANN RICHARD
IPC: B01D53/04
Filed: 1994-03-21
Abstract: In the device to remove solvent vapours from effluent air, the air is exhausted from the work space (2) and ducted to two or more parallel active carbon adsorber units (10 to 13). Each absorber can be switched between charge mode (in which the solvent vapours are received) and the regeneration mode (in which the carbon is regenerated). The novel aspect of this device is that before the end of the regeneration phase, each absorber unit is dried by air drawn from the work spaces, which is then ducted to an absorber operating in the charge mode. During those periods when an adsorber unit is being charged, it runs first of all through an initial period followed by a main phase during which time air (a) flowing from an adsorber in the main phase is immediately returned to the work space, while air (b) from an adsorber in a start-up phase is kept separate from other air (a,b).
