Title: Folding door having a plurality of leaf pairs
Inventor: BRAKMANN RALF DIPL ING
IPC: E05F15/605
Filed: 1988-09-21
Abstract: The invention relates to a folding door having a plurality of leaf pairs, the leaves of which are connected to one another in an articulated manner and which can be folded out of a stretched-out closed position into an opening position and can be displaced along a horizontal guide rail. Said folding door is intended to be configured such that easy opening is just as possible as convenient closing. This is achieved in that connected to the first leaf pair (1), as seen in the folding direction, is a motor-drivable displacement device for displacing the leaf pairs (1, 2) in the opening and closing directions. It is particularly expedient to couple to the displacement device a folding device for the first leaf pair (1). <IMAGE>

Title: Process for reprocessing slags from metallurgical processes with recovery of soda
Inventor: ENSS JUERGEN DR
IPC: C01D7/07
Filed: 1988-10-31
Abstract: The invention relates to a process for reprocessing slags from metallurgical processes with recovery of soda (sodium carbonate). In processes customary hitherto, the soda-containing slag from a pig iron desulphurisation and/or dephosphorisation is leached at relatively low pH values with simultaneous addition of carbon dioxide or treated under increased pressure (superatmospheric pressure). Sodium hydrogen carbonate is largely formed here, and only slags formed in soda desulphurisation can be used. In contrast, according to the process of the invention other slags from metallurgical processes, in particular including calcium carbide slags and/or magnesium slags can also be used. The slags are leached with hot water at from 80 to 100@C and pH values between 12 and 13.5. Subsequently, precipitation with carbon dioxide is carried out in the presence of one or more additives, with the additives very largely preventing adsorption or deposition of sodium on the precipitation products. Hydrogen sulphide formed is processed to give sulphur or sulphuric acid, and soda is recovered from the soda solution of the precipitation stage.

Title: Device for preforming a moulding compound to be processed in a compression mould
Inventor: BRUESSEL RICHARD DIPL ING
IPC: B29C43/32
Filed: 1989-02-10
Abstract: In the processing of moulding compounds whose side sections protrude beyond the end face of the lower part of the compression mould there is the risk of the side sections being taken up by the upper part of the compression mould and displaced in an undesirable way before the actual pressing operation begins. This has the consequence of an unreproducible pressing operation and consequently the production of mouldings of varying quality. To improve the cost-effectiveness of the production process - including from the aspect of automation - the proposal is made of integrating into the compression mould a device for preforming the moulding compound (5). For this purpose, the upper part (1) of the compression mould is equipped on its side facing the lower part (2) with moulding jaws (6) projecting towards the centre axis (4) of the compression mould. These are designed in such a way that the side sections protruding beyond the lower part end face (2e) are bent around as the upper part (1) and lower part (2) approach each other, before the moulding compound (5) makes contact with the forming area (1c) of the upper part (1). <IMAGE>

The workpieces can be removed from the conveying frame (21) in a tier-by-tier fashion, can be successively processed and returned to the store resting on their base surfaces (Fig. 1). <IMAGE>

Title: No-break power supply device for data processing systems
Inventor: BOEDEN BERNHARD
IPC: G06F1/30
Filed: 1989-06-13
Abstract: The no-break power supply device for data processing systems is connected for continuous operation between the mains connection and the inputs of the power supply of the data processing system, and has a rectifier, an accumulator and control devices. Spatially, the power supply device is integrated in the data processing system or arranged outside it. The output of the rectifier is directly connected to d.c.-d.c. converters with different output voltages, and the outputs of the d.c.-d.c. converters are directly connected to the inputs of the power supply of the data processing system (e.g. CPU at 5V, floppy disk drive at 12V). If there is a mains failure, work in progress is first brought to a definite end. After the failure ends, the accumulator is fully charged, and operation of the computer then continues (Fig. 2). <IMAGE>

Title: Domestic coffee machine
Inventor: LANDAIS FRANCIS PIERRE JACQUES
IPC: A47J31/58
Filed: 1989-06-19
Abstract: A domestic coffee machine has in a housing a cold-water receptacle and a continuous-flow water heater with rising pipe to an overflow, from the outlet of which the hot water flows down into the removable coffee jug via a removable filter.

Title: Carrier for developer for electrostatic latent image with resin coatin - contg. fine silicon resin particles to reduce surface energy
Inventor: TSUJITA KENJI
IPC: G03G9/113
Filed: 1989-08-06
Abstract: Carrier suitable for use in the development of electrostatic latent images has a core material with a resin coating contg. fine silicone resin particles (I) with an average particle size smaller than the thickness of the resin coating. Pref. (I) have a particle size of max. 3 microns and are used in an amt. of 5-50 wt.% w.r.t. the resin coating.  The coating is based on styrene or acrylic type resin and is produced by a dry technique. USE/ADVANTAGE - (I) reduces the surface energy of the coating, without impairing its strength.  This prevents the problem of 'toner spending' with repeated use.  Heat treatment is unnecessary, since the resin need not be cured, which avoids fluctuation of the triboelectric characteristics during mfr.  and ensures constant quality.  The carrier can be produced eaisly and does not agglomerate.

Title: Continuous panel cladding - by applying adhesive to successive panels and cladding film as they move together on converging paths
IPC: B32B/
Filed: 1990-07-24
Abstract: The continuous cladding process, to coat panels or bars with a material which can be shaped at a later stage, applies adhesive simultaneously to the rough surface of the carrier and the smooth surface of the cladding while they are moving together on a converging path. While still moving, the adhesive-coated cladding material is heated to activate the adhesive. The cladding material is then applied to the carrier, as they are brought together, and the required shaping is effected at the edges of the carrier panels or bars and the like. ADVANTAGE - The technique gives a continuous cladding action to panels or bars fed in succession to the application point.

Title: Presetting phase-regulated VCO - reading-out corresp. adjusting values for several frequencies from memory for respective voltages
Inventor: HOLZMANN GOTTFRIED DIPL ING
IPC: H03L7/189
Filed: 1990-10-09
Abstract: The VCO is phase-controlled by the voltage of a sensitive phase detector. It is adjusted to a preset frequency value by a supplied adjusting voltage together with the control voltage of the phase detector. The preset adjusting voltage is generated by digital adjusting values, corresp. to the control voltage-frequency characteristic of the oscillator and stored in a memory. For several frequency values the respective adjusting values are read-out from the memory and the respective preset adjusting voltages supplied to the oscillator. The phase detector is controlled by a voltage comparator, acting on the respective adjusting values. The corrected adjusting values are then computed. ADVANTAGE - Improved adjustment even if control voltage-frequency characteristic deviate from ideal value.
