Patent DE-3800654-A1 (DE)
Title: Pressure regulating valve
Inventor: BARTH HANS
IPC: G05D16/20
Filed: 1988-01-13
Abstract: A regulating valve (1) has an inlet (2) and an outlet (3) for the medium to be controlled, as well as a valve body (6) guided in a housing. The valve body is connected to a membrane (4, 4a), the membrane (4) bounding a pressure chamber (5). Depending on the pressure pad prevailing in the pressure chamber (5), a more or less wide opening of the regulating valve, and thus an alteration on the outlet side (3), results. Connected to the pressure chamber (5) are two control valves (12, 13), by means of which the pressure in the pressure chamber (5) can be varied. The control valves are connected to an electronic controller (19), which obtains its actual value information from an actual value transmitter (21) arranged on the pressure output (3). The control valves (12, 13) are preferably closed in the non-driven state, so that they have to be driven only for the very short phases of an alteration of the pressure inside the pressure chamber (5). Altogether, by this means, only a very small energy demand is necessary for the pressure control valve (1). <IMAGE>

Title: Method and arrangement for allocating an identifier for traffic monitoring and control to digital signals DS140, DS34 and DS2
Inventor: KOLLMEIER MANFRED DIPL ING
IPC: H04J3/12
Filed: 1988-08-02
Abstract: The traffic in a transmission network with switching devices for digital signals DS140, DS34 and DS2 can be monitored and controlled with the aid of individual identifiers which are transmitted in a signalling bit of the respective digital signal. An identifier is sought which can be quickly and reliably synchronised and can be easily processed in a computer. The identifier comprises a number of octets (O1-O4) for an identifier text and one octet (O5) for an identifier header. A filler bit (F) or a filler bit string is placed between the octets. The bits in the identifier header and the filler bits (F) are assigned the logical value one (shaded). The identifier text can be selected as required. This identifier (a) is in particular CMI-coded (b). A code rule violation occurs in each filler bit (F) or each filler bit string. With the aid of this, the octet clock can be synchronised in one step and the identifier can be synchronised in a further step with the identifier header. The octets can easily be evaluated in a computer. The invention is advantageous for monitored and controlled transmission networks with switching devices for digital signals DS140, DS34 and DS2. <IMAGE>

Patent DE-3911596-A1 (DE)
Title: Comminuting appliance
Inventor: HAEUSLER DIETRICH
Filed: 1989-04-08
Abstract: The comminution of refrigerating assemblies, such as, for example, refrigerators and freezers, generates fluorochlorohydrocarbons (FCH) which are contained therein as a refrigerating medium and/or as an integral part of the insulating materials and which have hitherto passed into the free atmosphere in an uncontrolled manner. A suction-extraction of the liquid refrigerant and a removal of the FCH-containing insulating materials by manual labour in advance of the mechanical comminution is too complicated, time-consuming and very expensive. In order to make do without dismantling and disposal work of this kind and in order to prevent released fluorochlorohydrocarbons (FCH) from passing into the free atmosphere during the mechanical comminution of the refrigerating assemblies, comminution takes place in a comminuting machine having a vertically arranged rotor (2). The interior (4) can be closed off against the environment by means of a lock (6) in the upper feed device and a lock (12) in the lower emptying device. A part quantity of the air quantity circulated in the interior (4) as a result of the fan effect of the rotor (2) is suction-extracted out of the interior (4), freed from coarse and fine suspended particles in pneumatic separating devices and subsequently fed for FCH removal to a solvent-recovery apparatus = waste-air washer. <IMAGE>
Patent DE-3912569-A1 (DE)
Inventor: KRUEGER WOLFGANG DIPL ING
IPC: H05B6/70
Filed: 1989-04-17
Abstract: In useful volumes which are preferably extended in one direction, high-frequency fields are to be coupled to provide a desired distribution of the h.f. power in a lossy medium introduced into the useful volume. This is achieved by imposing a phase wavelength in the largest longitudinal extension of the useful volume lying near the longitudinal extension of the useful volume (1) or above it, or by imposing an aperiodically damped wave in this direction, so that the high-frequency power is correspondingly coupled to the desired field cycle largely vertically to the direction of the longitudinal extension in the useful volume. In the relevant device with a linearly extended useful volume, said volume (1) is inside a coupling volume (2) which has at least one coupling wall (30, 30') with coupling apertures (31 to 34) for the distribution of the h.f. power over its entire longitudinal extension and is powered from a distributor volume (40, 40').
