Patent DE-19709794-A1 (DE)
Inventor: HEINZ RUDOLF DR
IPC: F02M47/02
Filed: 1997-03-10
Abstract: The invention relates to a valve for controlling fluids in which the valve element (22) can be displaced by an actuating piston (25) which together with a piezoelectric actuator piston (33) defines a pressure chamber (31). The actuator piston and corresponding piezoelectric element (30) are positioned parallel to the actuating piston (25). When the piezoelectric element (30) is excited or the actuator piston (33) is displaced, the actuating piston carries out a movement in the opposite direction of the control displacement and with its valve element (22) controls the opening of a relief hole (19).

Patent DE-19716589-A1 (DE)
Inventor: MELCHIOR WOLFGANG
IPC: A62C35/62
Filed: 1997-04-21
Abstract: The pipeline system from the dry alarm valve (3) to the sprinklers is filled with compressed air. The alarm valve is held closed by pressure compensation on the air and extinguishing water side and opened when pressure drops on the air side. The pipeline system is rapidly ventilated by a pneumatic device and the dry alarm valve is rapidly opened by a separate pneumatic device. The quick opening for ventilating the pipeline system takes place before the rapid opening of the dry alarm valve. The rapid openings are undertaken by separate throttle stretches. This ensures that the throttling for the ventilation is greater than the throttling for opening the alarm valve. Diaphragm valves can be used to control the ventilation of the pipe system and the opening of the alarm valve.
Patent DE-19721355-A1 (DE)
Title: Riveting with a coated rivet that also deforms to clamp-up workpieces
Inventor: AURENTZ JOHN A
IPC: B21J15/02
Filed: 1997-05-22
Abstract: A method of connecting two workpiece sheets together comprises one of the sheets having a rivet hole bore provided with a frusto-conical counterbore to receive a rivet with a conical shaped head and the other workpiece sheet has a plain bore rivet hole so that the two sheets can be connected together. To obtain a compressive clamped-up retaining pressure between the  worksheets the head of the rivet is provided with a ringed shaped  domed top surface which when the rivet head is flattened during rivet fastening and deformation,the shank of the rivet and the underside of the conical interface expand radially outwards to fill in rough finishes,out of roundness and eliminate air gap possibilities. The ringed shape dome on the rivet head has a metallic volume B, and the space between the sheet hole, counterbore and rivet body has a volume A, and volume B exceeds volume A so that on deformation volume B expands into volume A pushing outwards against the workpiece. Coatings and sealants applied to the rivets provide barrier material to the dome head and rivet shank to fill interstices between the worksheets and rivet, effectively minimizing or eliminating exfoliation, electrolytic and stress corrosion.

Title: Filigree porcelain structure for molding decorative figurine
Inventor: HERMANN CARLA
IPC: C04B41/50
Filed: 1998-02-11
Abstract: To shape a material with a lace appearance, a patterned textile fabric with a large surface is used as a carrier and structure layer (1) to be coated evenly with a cladding mass. The coated fabric is stretched and dried, and the dry coating is moistened until it is tacky without spoiling the structure. The tacky coating is cut and shaped, and applied to a porcelain figurine. During firing, the carrier/structure layer is burned off, leaving the structured coating as a large surface porcelain coating. The textile layer has a filigree patterning, similar to a curtain, with a width of 30 cm and a length of 0.5-2.0 m.  The layer is of cotton or synthetic materials, or a mixture of them. The coating is applied by a roller over the textile fabric surface. An Independent claim is included for a porcelain coating mass of 6.5-7.3 kg, comprising 5% malachite and kaolin EKA-5, soapstone, talcum and colored particles to a total of 5%. The mass is ground, sieved a number of times and worked into a glutinous mixture using 3.5-4.0 l of a liquid glazing at 453/25 deg Re', 800 ml dextrin and 30-50 drops of a conserving agent. The ingredients are mixed and stored for 14 days. After remixing, it is worked again into a glutinous mass. Preferred Features: The colored particles, if required, are added during the second mixing stage of the coating mass.
