Title: Shut-off valve for borehole heads
Inventor: MOLLER FALK VON
IPC: E21B34/02
Filed: 1982-10-07
Abstract: A shut-off valve for borehole heads of crude-oil or natural-gas delivery installations is specified which contains a spade which can be axially displaced by means of a spindle. A flow opening running transversely to the axis of the spade can be shut off by the displacement movement of the latter, the spade being guided in an intermediate ring which is inserted into the valve housing coaxially to the flow opening and bears with its end faces against shoulders, lying opposite one another, of the valve housing, split symmetrically to the axis of the spade, while one sealing ring each is guided in between. Here, the sealing rings each consist of a metal ring filled with gas.

Title: Decanting device for liquids
Inventor: ESSER GERHARD
IPC: B65D47/34
Filed: 1982-10-18
Abstract: To improve the emptying of mutually exchangeable liquid containers with a standardised opening, a decanting device is placed in a sealing manner on said opening, which decanting device is provided with a pressure generator, a liquid riser pipe, a shutoff valve, an outlet pipe and a non-return pressure valve so that the liquid in the liquid container, subjected to gas pressure or to air pressure due to the pressure generator, can only pass to the outside via the outlet pipe for emptying through the riser pipe by opening the shutoff valve. This avoids a continuous pumping operation.

Title: Device for compression control
Inventor: ADAMIS PANAGIOTIS DR ING
IPC: F02D15/04
Filed: 1983-03-18
Abstract: A device for controlling the compression ratio of a reciprocating piston internal combustion engine has an auxiliary piston which is assigned to each cylinder of the internal combustion engine and varies the volume of an auxiliary chamber connected to the cylinder working chamber, which piston can be adjusted, by means of an adjusting device, as a function of a characteristic status variable of the internal combustion engine. In order to ensure optimum combustion at any time regardless of the output of the internal combustion engine and of the fuel quality, it is proposed that the characteristic status variable be the start of knocking combustion in at least one of the working chambers of the internal combustion engine. To this end it is proposed that at least one measuring transducer (12) be provided which detects the start of knocking combustion in at least one working chamber (4) of the internal combustion engine (1), as a function of the signals from which the adjusting device (11) assigned to the auxiliary piston (10) can be actuated.

Title: Doors and windows on roller bands suitable for removal and reuse
Inventor: RADEBOLD CLAUS
IPC: E06B9/40
Filed: 1983-08-16
Abstract: Doors and windows become usable for installation, removal and reuse in that roll-up door leaves and window wings are guided on roller bands at the top and bottom during opening and closing. To open and close the doors or windows, therefore, there is no need for door frames and window frames, their function being performed, in principle, by the roller bands. Various fixing devices make it possible to adapt the installation and, after their release, the removal of the doors and windows to the site conditions, without the installation or removal resulting in damage, for example to the masonry. An adaptation to different clear widths is possible to a limited extent. The locking of the door or window is carried out without attaching a fitting to the masonry, but by means of a fitting which is integrated in the door or window and which also allows fixing in a specific opening position.

Title: Bandaging material (cellulose gauze compress)
Inventor: SEITZ FRITZ
IPC: A61F13/00
Filed: 1983-12-09
Abstract: The invention relates to a bandaging material made of a gauze fabric or a bonded fabric on the wound side and cellulose absorbent layers. The gauze fabric and the cellulose layers can be connected to one another by lateral seams. A bandaging material is also known in which a bonded fabric used as wound cover is bonded with the cellulose absorbent layers by means of an alcohol-soluble adhesive. The invention is based on the object of providing a bandaging material of the above-mentioned type in which the adhesive bond between the gauze fabric and the cellulose absorbent layer at the same time brings about an additional active healing effect and in which the bandaging material can no longer adhere to the wound. For this purpose, the gauze fabric (or the bonded fabric) and the cellulose absorbent layer facing it are bonded to one another by means of a wound adhesive.

Title: Multi-purpose grilling device for vertical or horizontal operation
IPC: A47J37/04
Filed: 1984-01-13
Abstract: The grilling or cooking of relatively large pieces of meat or of poultry, for example, is preferably carried out using grilling apparatuses having an arrangement and device for horizontal bearing of one or more food supports opposite sources of heat which are arranged in vertical or horizontal planes. Meat, which is formed into a shape from, for example, minced meat or thin slices and is arranged on a spit, has to be arranged vertically, seen in terms of the support device, in order to prevent the small parts from dropping down during the relatively long grilling operation and when cutting off portions. Using the grilling device according to the invention, which can be used in two operating positions, the grilling operations can be carried out in only one combination apparatus which can be converted and/or is to be arranged in total or accordingly with the essential parts. With the arrangement according to the invention, a device for collecting the grilling vapours by means of exchangeable filters can be arranged for the vertical mode of operation, e.g. in a construction as a table top apparatus.
