Patent DE-4209891-A1 (DE)
Inventor: DISCHER HEINZ-PETER
IPC: C22B13/06
Filed: 1992-03-26
Abstract: The metallurgical-works dust is taken to a first furnace atmosphere, preferably at 1000 to 1100  DEG C. The dust pellet is kept with continuous agitation therein until especially chlorine, alkaline and lead compounds have virtually totally evaporated from the dust. Experience shows that this takes an hour. A stream of flushing gas is fed into the furnace atmosphere so that the lead-chlorine-alkaline vapour is taken from the rotary tube furnace to a condensation and filtering installation. Reducing agents, especially carbon, are then added to the metallurgical-works dust, which is taken to another hot furnace atmosphere, especially at 1150 to 1350  DEG C and continuously agitated therein. This reduces the zinc oxide in the dust, while the dust remains in the furnace until substantially all of the zinc has evaporated as metallic zinc vapour from the dust into the oxygene-containing furnace atmosphere and the metallic zinc has been converted into zinc oxide. Experience has shown that this takes up to two hours. Here, too, a stream of flushing gas is fed into the furnace atmosphere and takes the zinc oxide out of the furnace and the flushing gas with the zinc oxide is cooled and filtered.

Title: Natural fillers esp.for packing - consist of pieces of stems from plants with high pith or pulp content
IPC: B65D81/09
Filed: 1992-07-06
Abstract: A filler, esp. for packing consists of pieces of stems from plants contg. a lot of pith or pulp. The plants used are C3 and C4 plants (such as maize, Sorghum bicolor, Durrha, rushes) or Scirpus lacustris. The plant stems are in dry torn and the leaves have been removed. They are cut into lengths of 0.5-10(esp. 2-5, esp. pref. 2-3)cm. The ripe plants are left in the fields until the solids content is 80-90% and the plants which have dried in the field are then harvested using a harvester. The plant stems, or plant stem bundles produced are then cut, with or pref. without the leaves. The leaves can be removed mechanically, esp. by blowing air through the stems. USE/ADVANTAGE - The filler are very light natural, biodegradable fillers which will rot and can replace the use of synthetic, packing materials such as styropor. They are non-dusting unlike previously used natural fillers, e.g. popcorn. The prepn. of the fillers requires very little energy as they are left in the field, in the sun and then harvested. The fillers can also be degraded in an ecologically friendly manner by CO2-neutral combustion. Alternatively, they need not be degraded, but can be used as animal feed. Fallow land can be cheaply reactivated by using it to grow the fillers. The fillers can be used to pack toys and games, esp. the moving components of recreational or educational toys or games. They can also be used as carrier for perfumes, esp. aromatic materials used against vermin, eg. as carriers for coffee wax and esp. for plant tonics. The fillers can also be used as pore formers in the prepn. of porous building materials such as pore concrete, insulation plates and bricks,. The fillers are need in bags, esp. made of paper.

Title: Method for liquefying gases, characterised in that liquid gas is evaporated at high pressure, expanded, liquefied, supercooled and, in the heat exchanger, is used as the coolant
IPC: F01K25/10
Filed: 1993-02-16
Abstract: 1) Method for liquefying gases, characterised in that liquid gas is evaporated at high pressure, expanded, liquefied, supercooled and, in the heat exchanger, is used as the coolant. 2) The previous methods for gas liquefaction require up to several compression and cooling stages and a correspondingly high cost in terms of installations and energy. 3) Liquid gas is delivered by a pump under high pressure into a heat exchanger and is evaporated there by supplying heat (e.g. waste heat or ambient heat). The vaporous or gaseous gas is expanded, involving a large drop in pressure, and in the process is cooled down to liquefaction, and supercooled. The supercooling of the liquid gas is utilised for cooling and liquefaction of gaseous gas in a liquefaction and collection vessel, the gaseous gas flowing in from a separate container or being forced into the heat exchanger by means of a compressor. The liquid flows back to the pump, in a closed loop, via a manifold. 4) The novel, simplified method for gas liquefaction reduces the cost in terms of installations and energy.

Title: Process for lettering sloping surfaces, in particular key caps (push-button caps), by means of a laser
Inventor: JOBST HANS DIPL ING
IPC: B41M5/24
Filed: 1993-08-11
Abstract: When lettering sloping surfaces, e.g. key caps, by means of a laser, the lettering is often distorted. The process according to the invention avoids this disadvantage in that the lettering to be applied is distorted in a distortion module independently of the angle of incidence of the laser beam onto the sloping surface, and the laser beam is controlled with this pre-distortion. A further process consists in bringing the object containing the sloping surface into such a position that the laser beam makes contact vertically with the sloping surface to be provided with the lettering. An arrangement for this purpose is likewise specified. <IMAGE>
