Title: Gas turbine engine with device for bleeding air from a diffuser
Inventor: EXLEY J T
IPC: F02C7/32
Filed: 1979-05-08
Abstract: In a gas turbine engine an auxiliary airflow is provided to power accessories. This auxiliary airflow is obtained from a bleed aperture 7 which is constructed immediately downstream of a diffuser vane 3 in a cusp 6 which is formed in the trailing edge 5 of the vane to provide inertial separation. This high-energy air from the diffuser is used as the primary airflow in an ejector 10 to draw ambient air into the auxiliary airflow to lower the temperature of the bleed air. The ejector is constructed to automatically adjust the amount of ambient air according to the energy of the bleed airflow by means of a piston-actuated spike 13 mounted for sliding movement in the primary nozzle. The spike varies the volume of flow through the primary nozzle according to the pressure exerted by the airflow on the piston. <IMAGE>

Title: Method for closing, pressurising and opening presses for membrane filters and arrangement to carry out the method
Inventor: OLENFALK L
IPC: B01D25/02
Filed: 1981-10-05
Abstract: The invention concerns a method for closing, pressurising and opening filter presses for membrane filters with a fixed upper yoke 6 and a lower yoke 7 which can move on vertical press columns 2, and its purpose is to improve the attending and the construction of such membrane filter presses. This is accomplished according to the invention by a method wherein a loose lifting tool 10 is placed beneath the moveable yoke 6 and set in operation, whereby the yoke and the press plates located in between are pressed against each other, after which the moveable yoke 6 is locked in its position, or upon opening of the press it is released, after which the lift tool is shut down and removed. An arrangement for carrying out the method is characterised in that there is an intermediate space 14 between the moveable yoke 6 and a counter support 4, in which a lifting tool 10 can be placed and set in operation or shut down. Furthermore, an adjustable stop arrangement 15 with shoulders 16 is mounted on the columns between the yokes 6, 7 and can be placed under any desired pressing plate 17 and support it when the moveable yoke 6 is lowered. <IMAGE>

Filed: 1983-02-04
Abstract: Packing containers with fold-out pouring spout are used for a great number of beverages, e.g. milk. The pouring spout comprises a number of connected triangular wall panels which are delimited by folding lines. On opening the pouring spout is folded out and the packing container is opened in that an outer end of the pouring spout is removed. To prevent the pouring spout from reverting to its folded-in condition after the opening the folding lines which delimit the material panel of the pouring spout from the upper side of the packing container are arranged so that they run at unequal angles. In this manner the breaking open and the forming of the pouring spout are facilitated.
