Patent DE-3238149-A1 (DE)
Title: Device for atomising, dispersing and mixing fluids
IPC: A61M11/06
Filed: 1982-10-14
Abstract: The invention relates to a device for atomising fluids, in particular for inhalation purposes, in which a gaseous pressure medium emerging from a compressed gas channel in a nozzle body sucks in the fluid to be atomised out of at least one intake channel adjacent to the compressed gas channel and in which a gas stream directing element is arranged opposite the compressed gas outlet opening in the outlet cone of the compressed gas. The emerging compressed gas is made to rebound and fan out, respectively, against this gas stream directing element. According to the invention, in such a device the upper end face (14) of the nozzle body (5) facing the gas stream directing element (15) falls away from the compressed gas outlet opening (11) towards the intake opening (19,20) of the intake channel (12,13). In addition, the underside (16) of the gas stream directing element lying opposite this face is directed in such a way that the end face of the nozzle body which falls away with increasing distance from the extended axis (18) of the compressed gas channel (6) moves away from this end face. As a result, when the airstream is switched off, a droplet of fluid is prevented from remaining between the upper end face of the nozzle body and the underside of the gas stream directing element, in which droplet a stream of fluid could pass from the intake channel into the compressed gas channel. <IMAGE>

Abstract: The longitudinal guide consists in a known manner of two longitudinal rails, which can be displaced with respect to one another, rest on one another via guidance means, and in each case have at least one U-profiled region which is composed of two limbs and a base. The bases of the two rails run parallel to one another and, together with the mutually overlapping limbs, bound an inner cavity. At least one limb of each rail has, on its free end, an envelopment region which is angled with respect to the limb and, with said limb, forms a hook. At least one envelopment flange of a rail engages in the hook-shaped region between the envelopment flange and the limb of the other rail. Guide means rest on the envelopment flange of at least one rail.

Title: Conveying device for loosening, metering and discharging chips and fibrous and farinaceous substances from a storage silo
Inventor: RUEEGSEGGER WALTER
IPC: B65D88/68
Filed: 1983-02-15
Abstract: The conveying device is used for the loosening, metering and discharging of chips and fibrous and farinaceous substances from a storage silo (1). A tube (2) is arranged in the silo (1) above a discharging worm (3) so as to cover the worm (3) in its longitudinal direction. Clearing springs (5) which project from the tube (2) and are provided with scraper discs (4) are attached on the tube in the direction of rotation of the tube (2). When the covering tube (2) is rotated, the clearing springs (5) engage with the conveyed material which has been introduced above and near the covering tube (2), and loosen it. The loosened material thereby falls onto the worm (3) which is located under the covering tube (2). A level sensor (12) is arranged in the space between the covering tube (2) and the worm (3) to stop rotation of the covering tube (2) when the worm (3) is covered with chips and to continue the rotation as soon as the worm (3) has reduced the layer of chips lying over it to the level set by the level sensor (12). This conveying device has a large output and is very effective, even though it is simple to set up and reliable in operation. <IMAGE>

Arranged on the transverse clamping jaw close to the device and the transverse clamping jaw (3) at a distance from the device is at least one guide rail (17) or a further guide rail (12) which extends in the direction of the transverse clamping jaw at a distance from the device or the transverse clamping jaw (1) close to the device respectively and which runs perpendicularly to the longitudinal extent of the transverse clamping jaws. The guide rails are mounted in guide shafts (15, 16) which are interconnected rigidly. An actuator (2) actuates the transverse clamping jaws. <IMAGE>

Title: Vertical-hook composite mat
IPC: E21D11/15
Filed: 1983-08-31
Abstract: A composite mat consisting of longitudinal and transverse bars crossing one another is provided for the permanent lining of roadways in underground mining and tunnelling. The longitudinal bars of the composite mat have a vertical hook at one end and a load-displacement part, doing work of deformation when compressive and tensile forces occur, at the opposite end. This load-displacement part to be deformed is designed as a wire bent in a hairpin shape and as such is welded to the end of the longitudinal bar or as such is bent out of the latter. Further ways of influencing the curve in the load-displacement diagram are obtained from the shaping of the slip ring, all parts and thus the entire vertical-hook composite mat being simple to fabricate. <IMAGE>

Inventor: BAUER KURT
IPC: B60S1/38
Filed: 1983-10-29
Abstract: The wiper blade for vehicle windows has a carrying frame and a wiper strip consisting of rubber-elastic material and having longitudinal side grooves. Holding claws of the carrying frame engage in said grooves. The said claws are closed at one end of the wiper strip and have, at a distance from the closed end, a transverse web which engages behind one edge of a holding claw resting against the end. In order to improve the force transmission from the carrying frame of the wiper blade to the wiper strip, a further transverse web which engages behind an edge of the holding claw adjacent to the holding claw resting against the end of the groove is located in each longitudinal groove. A wiper blade of this kind is particularly suitable for an extendable wiper system in which the effective length of the wiper arm changes during a wiping cycle.
