Patent DE-3034889-A1 (DE)
Title: Coating moulds with mould wash - by contact of mould wash aerosol with mould across which pressure gradient is established
Inventor: BARTSCH DIETMAR
IPC: B05C19/02
Filed: 1980-09-13
Abstract: The mould wash, in the form of an aerosol suspension, is held in a deposition chamber, part of the wall of which is formed by the mould surface to be coated, and a pressure gradient between this mould surface and the outer surface of the mould is established to produce a gas flow from the chamber through the mould. Pref. the pressure gradient is established by applying a vacuum to the outer surface of the mould, the vacuum pref. being maintained until the mould wash coating is dry. Uniform mould wash coatings are produced rapidly and the coating dries rapidly from the inside layer to the outside layer (due to the directional flow of gas and entrained solvent vapour) so that the coating does not run. The gas permeability of the coating decreases rapidly with increasing coating thickness thus improving coating thickness uniformity even in e.g. recessed and upraised mould regions. Selective mould wash coating is possible by using gas-impermeable masks.

Title: Method for transmitting fault messages from a telephone PABX system to a service station
Inventor: HUTT HANS
IPC: H04Q1/26
Filed: 1981-03-19
Abstract: The method for transmitting fault messages from a telephone PABX system to a service station, results in high reliability existing in the establishment of connections via the public telephone network to the station (service station) which is intended to receive the fault messages. For this purpose, it is proposed that an exchange line is connected directly to the fault message transmitting device if it is not possible within the PABX system to set up a path to the public telephone network. It is furthermore provided that, by means of a return message, a service station causes the fault message transmitting device to set up a new connection to a different service station if the first service station is not manned. Furthermore, an additional telephone number is contained in the memory of the fault message transmitting device, with which a second connection can be set up if the first connection has been unsuccessful.
Patent DE-3111686-A1 (DE)
Title: Installation duct
Inventor: KNIER GUENTHER
IPC: H02G3/04
Filed: 1981-03-25
Abstract: An installation duct is described which is particularly suitable for use in laboratory rooms or in rooms which are cleaned moist or wet since it offers protection against moisture to the electrical functional elements arranged in it. In order to achieve this, individual duct part pieces from which the installation duct is constructed are connected to one another at the abutment points via sealing frames such that no moisture can penetrate at the abutment points. The removable covering profiles, which seal the installation duct towards the centre of the room, are also sealed in the region of the latching elements by means of which they are held on the duct lower part, so that no moisture can penetrate in from there either. Finally, sealing end pieces are inserted on the sealing frames which are placed on the ends of the installation duct.
Patent DE-3112078-A1 (DE)
Title: Hybrid plug connection for optical and electrical conductors
Inventor: LUDOLF WILHELM DIPL ING
IPC: H01R13/28
Filed: 1981-03-27
Abstract: In the case of a hybrid plug connection for the detachable connection of two identical cables having in each case at least one electrical and one optical conductor, the two plug elements in each case have an insulating body for accommodating and guiding the conductors, as well as their holding and contact parts. In order to achieve a hybrid plug connection which can be constructed and handled easily and is cost-effective (of this type) while at the same time ensuring reliable protection of the contacts, especially of the contact surfaces of the optical conductors, when the plug connection is detached, as well as exact contact-making of all the conductors which are to be connected, the plug elements are of identical (sexless) construction and can be connected by means of an adaptor piece which consists of insulating material, can be plugged onto the insulating body, is preferably attached thereto in a latching manner, completely surrounds (in the connected state) the free end parts (which project out of the insulating bodies when the cable is installed) of the optical conductors and of the contact parts of the electrical conductors, projects at the ends, and has an axial guide for the end sections of the optical conductors to be connected, as well as contact means for conductive connection of the associated contact parts of the two plug elements. In this case, it is particularly expedient for practical use that the adaptor piece is separated into an adaptor part and a protection part, with which each plug element is fitted when delivered, the protection part being only an insulating part with bushings for protectively surrounding the contact parts, and the adaptor part being used as a protection part and contact part for connecting associated conductors of the two plug elements, the axial guide being constructed as a stainless steel guide sleeve.
Patent DE-3113124-A1 (DE)
Title: Destination indicator with a rolling tape printed with destinations
Inventor: KRAUSE MANFRED ING GRAD
IPC: G09F11/295
Filed: 1981-03-27
Abstract: This rolling tape is moved by a motor past a viewing window by unwinding or winding up, the respective tape position being detected via lateral point or line markings on the rolling tape and scanning by light barriers, and when they correspond to a preselected destination, the drive is stopped. To simplify the operation and in case of a failure of the synchronisation, without which the various indicators of the vehicle drift apart after a certain time, it is proposed according to the invention that a destination-specific binary code word is allocated to each destination, that the code words passing through are detected by means of reflection-type light barriers (6) and compared with the code word set by means of coding switches (13) in accordance with the desired destination. In the case of inequality of the code words, a comparator (16) determines the direction of rotation of the drive motor and in the case of equality, it stops the drive motor. Advantage: detection of the destination is accurate and is carried out independently of any destination indicator. The rate of movement of the individual destination indicators becomes insignificant.

Title: Regulating valve for fluids
Inventor: KIPP GUENTHER
IPC: F16K1/12
Filed: 1981-09-02
Abstract: Particularly when solid particles are suspended in the fluid, even in high concentrations, fluid flows are regulated in free-flow valves through which the flow is axial. In order to keep the flow path essentially without deviations so as to achieve regulation of the fluid flow down to complete shut-off, where the gap between the sealing cone and the sealing seat is not to serve as the regulating element in the significant regulating range, and so as to be able to exchange all those parts of the regulating valve which are subject to wear in a simple and economical manner, the invention proposes to provide in the inlet of the regulating valve a non-displaceable flow-guiding and sealing body (16) which has a downstream extension (16.3) which is overlapped by an axially displaceable tube (20), the inlet end of which has an inflow nozzle (22) with a shape similar to a Laval nozzle, the regulating gap being formed between the Laval nozzle-like contour and the downstream end of the sealing-body extension. The flow-guiding and sealing body (16) is furthermore provided with the sealing seat (16.2) and the inlet nozzle (22) with its Laval nozzle-like contour with the sealing ring (22.1), the two finally resting against one another in a sealing manner when the valve is shut off. The flow-guiding and sealing body (16) is furthermore placed between the flanges of the valve inlet, which have a recess corresponding to the outer ring (15) of the flow-guiding and sealing body. <IMAGE>
