Title: Device for removing emissions at machine tools
Inventor: PESTER BERND DIPL ING
IPC: B23Q11/08
Filed: 1983-06-18
Abstract: The invention relates to a device for removing emissions in particular at mobile machine tools with a rotating cutting tool which are especially used for severing materials containing harmful substances. To prevent permanent damage to the health of the operating personnel, the emissions arising during the severing operation are to be completely removed. This is achieved by the part of the cutting tool 3 in engagement with the workpiece to be severed being completely enclosed by a brush system. This brush system consists of bristles 11; 12 which are of the same length or different length, surround the cutting tool 3 in several rows, and extend close up to the same. The brush system is carried by a frame 10 which is arranged at the splitting wedge 8 at a distance from and in parallel above the work table 2. The bristle length is such that at least the long outer bristles 11 reach down to the work table 2 and rest on it with slight pretension. <IMAGE>

Abstract: Diecasting machine and process for its control, its casting pressure being measured with a pressure sensor (PK, PZ, PG) on the casting cylinder (ZG), on the casting piston (K) or the casting hydraulics (HG) and fed to a control apparatus and evaluated there, so that the phases of compression, injection, secondary compression and mould opening are controlled as a function of the course of the process, and fault indications and quality features for the cycle, and control signals for the supply plant and closing apparatus (13,HS), are produced. The pressure indication signals are evaluated in conjunction with the signals of temperature sensors and path sensors (WG,ES). Relief phases are provided during the secondary pressing time for obtaining quality features, improving the foreign body separation from the melt, and indicating completed solidification. A vent provided by a slight opening of the mould in connection with a relief phase is shown. <IMAGE>

Patent DE-3413456-A1 (DE)
Title: Digital/analog converter
Inventor: ZIMMER MANFRED DIPL ING
IPC: H03M1/00
Filed: 1984-04-10
Abstract: A digital/analog converter for converting an N-digit digital code word, with N current sources for binarily stepped currents and N current switches which are driven by the individual bits of the code word. The code word is present in Gray code (G1 to GN) and directly drives the current switches (S1 to SN). The binarily stepped currents (I1 to IN) are in each case conducted from the outputs of the current switches (S1 to SN) to a first input of first current summation points (S). Each bit stage is associated with a current folding amplifier (SFV1 to SFVN) with amount-forming characteristic. The output currents (IE1 to IEN) of the first current summation points (S) are supplied to the inputs of the current folding amplifiers (SFV1 to SFVN) which in each case output a folding current (IF1 to IFN) and half a folding current (IF1/2 to IFN/2) at two different outputs. The half folding currents (IF1/2 to IFN/2) are in each case supplied to a second input of the first current summation points (S) of the next lower bit stage. At the first current summation points (S), the difference is formed between the binarily stepped current (I1 to IN) of one bit stage and half the folding current (IF1/2 to IFN-1/2) of the in each case preceding bit stage. The folding currents (IF1 to IFN) are supplied to second current summation points (S'). Their sum provides the output current (IA) of the digital/analog converter. <IMAGE>

IPC: G01F23/02
Filed: 1984-05-02
Abstract: A light beam (5) is transmitted at right angles through a level-indicating tube (1) to a photo-electric receiver (4).

Patent DE-3423992-A1 (DE)
Title: Cooling device for, in particular, switching cabinets
Inventor: KUEMMERLE BRUNO
IPC: H05K7/20
Filed: 1984-06-29
Abstract: A cooling device is proposed, especially for switching cabinets, which has two chambers, to one of which the switching cabinet air which is to be cooled is supplied, while environmental air, which is used for cooling purposes, flows through the other. A cooling unit, with a vaporiser and a condenser as well as a compressor, is arranged in both chambers. The vaporiser is located in the chamber carrying the switching cabinet air while the condenser is arranged in the other chamber which carries the environmental air. At least one heat exchanger is seated inside the second chamber, close to the inlet and in the region between the inlet and the condenser, which heat exchanger has oil which is to be cooled flowing through it, and whose heat exchanging surfaces are in heat-exchanging contact with, and are acted on by the environmental air which is passed through the second chamber. Thus switching cabinet air, on the one hand, and oil, on the other hand, are cooled in a single cooling device with one cooling unit.

Abstract: Chemically sensitive field-effect transistor sensor which is formed in a silicon-on-insulator substrate having a two-layer structure comprising a lower insulator substrate and an upper single-crystal silicon thin film uniformly applied to the lower insulator substrate, source and drain regions which are doped with impurities having a high concentration and, compared to the upper single-crystal silicon thin film, a different conductivity, being formed in the upper single-crystal silicon thin film and insulated from one another. A portion of the lower insulator substrate lying below an active silicon thin-film region, which is disposed between the source region and the drain region, has been completely removed up to the boundary between the lower insulator substrate and the upper single-crystal silicon thin film, the bottom side of the upper single-crystal silicon thin film, which as a result of the removal of this portion is exposed on the side of the lower insulator substrate, being utilised as a sensitive gate surface. An insulating layer and a chemically sensitive layer are deposited on the sensitive gate surface. The source and drain electrodes can be protected effectively against contact with a sample solution whose ion concentration is to be measured.

Title: Installation for regulating the amount of gas to be fed into a secondary distribution system from a high-pressure gas line
Inventor: STALLENBERG VALENTIN VON
IPC: G05D16/20
Filed: 1985-02-13
Abstract: The invention relates to an installation for regulating the amount of gas to be drawn from a high-pressure gas line and to be fed into a secondary distribution system which is at medium or low pressure. In this installation, a buffer accumulator is provided for equalising fluctuations of gas consumption. In order to enable essentially even off-take of gas from the high-pressure gas line, the object being to avoid exceeding the permitted maximum gas off-take amount per time unit, while employing the buffer accumulator which has a comparatively small volume, keeping investment costs low, and trying to minimise the amount of energy required for operating the installation, it is proposed that the buffer accumulator be connected to a pressure-boosting installation which is fitted with equipment as set forth in the claims. <IMAGE>
