Title: Vertical inlet pipe of a submersible screw pump - has returning screw above the pumping screw and the outlet
Inventor: HUEBERS ERNST
IPC: F04D3/02
Filed: 1974-01-15
Abstract: The immersed inlet pipe pump has a pipe whose lower end is below the surface of liquid to be pumped, and is used for lifting highly viscous liquids from a container to a higher level. The pumping action is provided by a helical ribbed screw at the lower end of the rotating spindle. This screw rotates within the pipe. The pump pipe is immersed into the liquid below its level. The hollow circular pipe contains the pump spindle which is driven by an electric motor mounted on the container lid. The spindle has at its lower end a helical screw which acts as a lifting screw for lifting and raising the liquid through the outlet pipe. Above the outlet pipe connection is arranged on the spindle a helical screw with the opposite helix to the pumping screw. This screw ensures that liquid does not rise within the tube and contacts the motor seal, and that the seal is not subjected to any wear or pressure forces. The pipe has near its upper end radial holes which act as overflow opening and any excess liquid is directed through these holes back into the container. In a preferred version a number of such overflow holes are arranged in the pipe wall above the returning screw level.
Patent DE-2406903-A1 (DE)
Title: Car radio tuning device with push-button station selector - with coupling device actuated after pre-locking to prevent de-tuning
Inventor: PROELSS HANS DIPL ING
IPC: H03J5/12
Filed: 1974-02-14
Abstract: An S-shaped clamping lever is provided with an engagement contour near one extremity that first applies a light preclamping pressure allowing a semicircular half disc to accommodate its position to that of the tuning element set by a tuning knob, as a station selector push-button is first moved from its extreme withdrawn position inwardly. Until this pre-clamping operation is completed, the tuning knob remains coupled to the tuning element of the radio receiver. As the push-button is further actuated inwards, an offset arm on a strip-shaped member operates a coupling device to release the coupling between the tuning knob and the tuning element. The clamping lever than progressively provides more force until it reaches a stable position where the half disc is locked to the tuning slide. The bearing element against which the contour of the clamping lever works is a roller bridging a slot in the inner end of the strip-shaped member, and the friction of the engagement is low enough so that if the stable locked position is not reached, a push-button will be restored to its withdrawn position by a leaf spring acting on the clamping lever.
