Title: Electropneumatic valve control
IPC: A01J5/10
Filed: 1982-03-09
Abstract: An electropneumatic valve control serves for the changeover from vacuum to atmospheric pressure in a working apparatus and is used, for example, as a pulsator for a milker used in vacuum milking installations. The valve control contains a main valve and an auxiliary valve, the main valve being in the form of a conical valve and serving for the communication between the working apparatus on the one hand and the vacuum source and the atmosphere on the other. The auxiliary valve serves for the control of the main valve which is fastened to a diaphragm. The auxiliary valve is in the form of a slide valve and has a recess into which a connecting passage opens during both the working phase and the rest phase of the control, and the connecting passage is connected to a chamber that is continually under vacuum. In the working phase the recess in the control slide valve establishes a connection between the connecting passage and a passage connected to the diaphragm chamber, the control slide valve being actuated by means of a double-action solenoid and the passage connected to the diaphragm chamber being connected to the external atmosphere in the rest phase of the control.

Patent ES-8406336-A1 (ES)
Title: Aircraft lift rotors
IPC: B64C27/32
Filed: 1983-09-26
Abstract: An aircraft lift rotor has at least one pair of diametrically opposed blades mounted so as to be rotatable about a common longitudinal axis (G), which is positioned forwards of the aerodynamic centre (O) of each blade, so that the aerodynamic forces on the blade produce a movement urging it to a smaller angle of attack, against the action of spring means (14). The combination of forwards motion of the aircraft and rotation of the rotor exposes opposed blades to different speeds of airflow, in which condition the freedom for each blade to rotate about its longitudinal axis causes the blades to adopt automatically dissimilar angles of attack, in response to the aerodynamic forces on the blades so that the forces on the opposed blades are at least partially equalised. To reduce bending forces in flight, the blades may also be pivoted at their roots on axes tangential to the rotor hub.

Title: Device for sorting fish
IPC: A22C25/12
Filed: 1984-09-14
Abstract: A device for sorting fish into uniform head-tail alignment is characterized by a truncated conic disc driven rotatingly about a horizontal axis, which disc, with its corundum-coated smaller frontal surface in connection with a gripping surface fixed to the frame of the device and opposing the frontal surface in the region above the axis, forms a gripping gap into which fish supplied with their tail end leading are introduced with their tailfins. Due to the rotation of the truncated conic disc the tail part of the fish is entrained by frictional engagement. During that process the fish is gradually placed on its tail so that a shift into the head-first position occurs, in which position the fish is set free at the end of the gripping surface.
