Title: Fluid-feed valve
Inventor: ISE YOJI
IPC: F16K31/36
Filed: 1985-01-28
Abstract: Fluid-feed valve (A) with a valve chamber (5) in which a valve element (8) is movably contained. The valve element (8) is actuated by the pressure difference between a fluid-receiving opening (4') and a fluid-discharge opening (6') in order to alternately close and open the openings (4', 6'). The fluid-feed valve body (1) also comprises a fluid-supply container (9) which is connected to the fluid-receiving and fluid-discharge opening (4', 6'). When the fluid-receiving opening (4') receives the pressure fluid, the valve element (8) closes the fluid-discharge opening (6'), and the pressure fluid is stored in the fluid-supply container (9) via the valve chamber (5). When the fluid-receiving opening (4') ends the receiving of the fluid, the valve element (8) closes the fluid-receiving opening (4') and opens the fluid-discharge opening (6') so that pressure fluid held in the supply container (9) is automatically supplied to the fluid-feed line (20). A vacuum gripping or clamping device which is actuated by an air ejector pump (12) uses a fluid-feed valve (A) of this type so that, when the air ejector pump (12) stops operating, the pressure fluid in the fluid-supply container (9) is supplied to the suction pad (18) via the fluid-feed valve (A) and the vacuum remaining therein can be quickly neutralized. In this way, with the use of a fluid-feed valve of this type with very ... results ... Original abstract incomplete. <IMAGE>

Title: Device for opening ventilation appliances
IPC: A62C2/24
Filed: 1985-01-30
Abstract: The relevent regulations rule that ventilation appliances equipped with a locking and release means must open automatically even when relatively high forces caused by snow or wind act on the ventilation appliance at relatively low outside temperatures. In the device according to the invention, two compressed-gas cartridges are assigned to a release means. To ensure functioning, there is arranged in a housing, above the plungers opening the compressed-gas cartridge, a spring-loaded pressure plate which can be moved by the release of the release means. The housing is provided, furthermore, with connections for the compressed-gas cartridges and with guides for the plungers. Nitrogen dioxide (N2) is provided as propellent gas for the compressed-gas cartridges, since the pressure drop can be ignored as a result of the thermal behaviour at the temperatures required. <IMAGE>

Title: Process for producing heat-insulated composite profiles for window frames or the like, metal profile for applying the process, and parting-off tool for carrying out the process.
Inventor: WIELEN FRED VAN DER
IPC: E06B3/267
Filed: 1986-02-06
Abstract: Process for producing heat-insulated composite profiles for window frames or the like, which exhibit at least two metal profiles which are connected to one another via at least one intermediate piece consisting of a heat-insulating composition. The two metal profile parts are initially connected to one another in one piece by at least one connecting web, consisting of the same material, and this results in at least one preferably outwardly open channel in which the heat-insulating position forming the intermediates is cast, the connecting web being parted off from the metal profile parts by a cutting procedure after the insulating composition has hardened. During casting in the channel, the insulating composition forming the intermediate piece produces, in the parting-off region between the connecting web and the metal profile parts, a non-load-bearing zone on the side facing the connecting web. Furthermore, during the parting-off procedure, the cutting edge of the parting-off tool is introduced, from the side facing away from the insulating composition, through the material of the connecting web and into the insulating composition in the non-load-bearing zone of the intermediate piece.
