Patent DE-4215886-A1 (DE)
Title: Coffee drink storage container e.g. for attachment to automatic coffee machine - has storage space of specified vol.surrounded by enclosing wall with filling and emptying opening for storing variable vols. of coffee drink and has unit preventing contact with oxygen in air
Inventor: ANDERL SIEGFRIED
IPC: A47J31/50
Filed: 1992-05-14
Abstract: The container (1) has an equalising compartment (10) contg. a vol. automatically matched to different filling amounts so that the largest vol. of the equalising compartment is the same or larger than that of the storing chamber (4) for the coffee drink. An inert gas, e.g. carbon dioxide is contained in the equalising chamber led across an equalising line (14) provided with a valve (15). With a reducing amount of coffee drink (5) the gas flows in the storage chamber (14), to fill the part of the vol. no longer occupied by the coffee drink. With an increasing amount of coffee drink, the gas flows in to the equalising compartment (10). The inert gas is essentially without a vacuum. A relief valve (18) and a non-return valve (16) are also in the circuit. A measuring sensor is provided for determining a critical value of oxygen concn. ADVANTAGE - Simple construction for economic operation. Coffee drink can be stored for long time without sacrifice of taste.

The optical alarm is an initial warning and/or the acoustic alarm is activated when the level reaches a max. height.
Patent DE-4302407-A1 (DE)
Inventor: IIO SATOSHI
IPC: C30B29/04
Filed: 1993-01-28
Abstract: A method for coating a substrate formed of a silicon nitride based material with a film of synthetic diamond by a gas phase synthesis technique including a first step of applying a film of synthetic diamond to a thickness of 0.5 to 2.0  mu  m at a temperature not higher than a temperature at which grain boundary components of the substrate volatilize, and a second step of applying a film of synthetic diamond to a thickness of 5 to 100  mu  m at a higher temperature, which expedites synthesis of the film of synthetic diamond. The silicon nitride based material may be Si3N4, or a silicon of the formula Si6-zAl2 N8-zO2 (where z is 0-4.2). The silicon nitride based material may contain sintering aids such as ZrO2 or MgO. The product has excellent durability and long service life because the film has tight adhesion to silicon nitride substrate due to nondegradation of the glassy grain boundary phase. The member may be used in a cutting tool, an optical material or an electronic material.

Title: Method and device for pelletising vegetable material, in particular stalked material
Inventor: HAIMER FRANZ
IPC: F26B17/20
Filed: 1993-04-06
Abstract: The invention relates to the pelletising of vegetable material for the production of pourable pressed pieces, in particular for heating purposes. In order to eliminate the moisture of the harvested material before pelletising, the invention proposes introducing the mown and comminuted vegetable material into a tubular shape of large diameter and small wall thickness which moves forward and to heat the tube thus formed from the inside and the outside. The moisture which as a result escapes from the material is carried off to the outside. Subsequently, the tube is transferred again into a lane of considerably smaller cross-section and led to the pelletising arrangement. In this manner, a high material throughput is achieved at the same time as a great drying efficiency. <IMAGE>

Title: Process for producing transporting crates from plastic
Inventor: DOEHREL HEIDI
IPC: B65D1/22
Filed: 1993-08-02
Abstract: A description is given of a process for producing transporting crates from plastic, in particular bottle crates, which have a base, a peripheral upper frame, corner supports between the upper frame and the base and outer walls, which are interrupted at least in the region underneath the upper frame, so that carrying grips are formed. For saving polymer material, and consequently costs and weight, in regions of relatively large cross-section, in particular in the region of the carrying grips, there are provided inner cavities which are not filled with the polymer material but are surrounded by it. In a known way, these inner cavities are hollow. Since, however, the production of such hollow profiles entails difficult production problems, it is provided according to the invention that, in the injection mould (1) for producing the crates, one or more inserts (2) are fixed, which are encapsulated with the polymer material over at least part of their surface and form the inner cavities. <IMAGE>
