Title: Radial compressor with maximal suction capacity - achieved through reducing impeller blades thickness from the centre to the outside
Inventor: KOTZUR JOACHIM
IPC: F04D29/44
Filed: 1974-03-23
Abstract: Compressor with fixed feed-in impeller and following rotor, achieves maximum suction by shaping and curving the impeller blades to reduce the flow angle from the centre to the outside. The rotor has an increasing outside diameter and/or exit angle from the wheel centre to the blade tip to transfer the same specific compression in all flow pipes.

Title: Plastic corner connector with at least three legs - used for the manufacture of metal frames which are electrically earthed
Inventor: GRAUPNER HANS
IPC: F16B7/04
Filed: 1974-04-27
Abstract: The connector is specially used for the manufacture of frames built up from square tubing and which are used for the support of medical electric equipment. The legs of the connector are split and wedge pieces are provided which have one chamfered edge. When the tube is forced over a leg of the connector, the edge of the tube slides over the chamfer and pushes the wedges piece between the two parts of the leg thereby forcing them against the side of the tube. The legs of the connector further have shallow grooves which are wider than the slot in which the wedge fits. A corrugated strip of metal is bent over at 90 deg. so that it can lie in the grooves of two legs. The tops of corrugated parts protrude slightly above the grooves. When tubes are pushed over the connector they will make electrical contact with the strip.

Title: Navigation with measurement unit operating with delta modulation - test valve integrated until following threshold switch responds
Inventor: HOFMANN FRITZ DIPL ING
IPC: G01C21/16
Filed: 1975-02-12
Abstract: A test value is at first integrated unitl a following threshold switch responds and releases a pulse from a generator connected through a synchronisation device. It sets back the integrator by a pulse weight and is simultaenously stored in a counter at the input of a navigation computor. The generator pulse release instant is adjusted by the synchronisation device to a time pattern corresponding to the computor's remaining periphery. The integrator input can be switched between different input sensitivities. The switching takes place when a week signal appears at the integrator output, requiring a switch over. The generator pulse release serves as the criterion for switching.
