Patent DE-4305866-A1 (DE)
Inventor: KLANE BERND DIPL ING
IPC: B29C48/14
Filed: 1993-02-25
Abstract: The process relates to the production of extruded foamed plastics, a foaming agent being fed under high pressure to the plastic conveyed in the extruder and the amount of foaming agent being controlled by a servo-valve. If there are fluctuations in the pressure of the polymer melt, the amount of fed foaming agent must be controlled correspondingly by the servo-valve (4). The regulating capabilities of customary servo-valves are often inadequate for this. Therefore, it is proposed to keep the pressure constant behind the servo-valve by means of a pressure-maintaining valve (5) and to control the amount of foaming agent directly as a function of the conveyed polymer melt, preferably via the extruder speed. <IMAGE>
Patent DE-4308802-A1 (DE)
Title: Door or window installation
Inventor: RITTER ALBRECHT
IPC: E05F15/643
Filed: 1993-03-19
Abstract: A description is given of a sliding-door installation with a motor drive. In the case of known installations of this type, the drive is covered from view by a covering hood. There is no dust-free termination with respect to the outside; rather, rubbed-off parts of the rollers and dirt can pass to the outside through the drive units. The novel development described relates to an installation in the case of which rubbed-off parts, dust and dirt are prevented from passing out of the drive, with the result that said installation can also be used for clean rooms. The units of the drive 5 are arranged in an enclosed receiving space 6. The running tube 4 is enclosed on all sides in the manner of a box and runs outside the receiving space 6. Provided in the vertical wall of the receiving space 6 is a slit 44s for the through-passage of drivers 58, 59 which couple the sliding leaves 1, 2 to the drive 5. The receiving space 6 is arranged in a drive case 60 which is delimited on its front side and rear side by wall elements 7, 8 which are arranged above the door. <IMAGE>

Title: Separating curtain for washing zones in belt- and basket-conveying dishwashing machines
Inventor: GERLACH MATTHIAS DIPL ING
IPC: A47L15/24
Filed: 1993-03-29
Abstract: Previous separating curtains consist of a material which does not ensure exact separation of washing zones and furthermore is subject to high wear. A separating curtain is presented which possesses the required properties     - suitable for food   - supple   - water-insoluble   - temperature-resistant   - resistant to detergent   - long service life.   This novel separating curtain is produced from three layers of glass-fibre cords and ensures much better separating-off of individual washing zones in belt-conveying or basket-conveying dishwashing machines. These curtains may be used anywhere, irrespective of the manufacturer of the dishwashing machines. Dimensional adaptations to the respective structural dimensions are no problem with this material.
