Title: Control for electromotor driving diesel-electric locomotive - drives mtor to high speed without forced commutation circuitry
Inventor: ALFRED LICHTENBERG DIPL-ING
IPC: H02P25/03
Filed: 1969-08-01
Abstract: The control circuit, for an electromotor driving a dieselectric locomotive, has pairs of antiparallel thyristors connecting the armature windings to the a.c. supply. The anti-parallel thyristors in the two separate antiparallel thyristor pairs that control currents through opposing armature windings, are themselves controlled so that during the first voltage half wave a current flows from the first supply pole over the first armature winding to the second supply pole, and in the following opposite half wave the current flows from the second supply pole over the second armature winding to the first supply pole. This firing sequence allows the motor to be driven directly to high speeds without forced commutation circuitry.

Title: Controlled release fertilizer coated granules
Inventor: HECHT HORSTMAR DIPL-CHEM DR RE
IPC: C05G3/00
Filed: 1970-04-30
Abstract: Fertiliser granulate with controlled nutrient release consists of (a) an at least partially water-sol. fertiliser salt core surrounded by (b) a water-insol. synthetic resin layer in which there are embedded, in an amount of up to 50% of the total weight of the synthetic resin layer, finely-divided solid elements of cpds. e.g. carbon in its various forms, sulphur (esp. flowers of sulphur), boron, silicon or red phosphorous which are compatible with the plants which are to be fertilised and with the ingredients of the fertiliser.

Title: Reclining back rest mechanism for automobile seats - continuous adjustment of back rest inclination using toothed rack and retaining plates
Inventor: PFEIFFER KLAUS
IPC: F16H27/10
Filed: 1973-12-04
Abstract: The position of a reclining back rest of a car seat is continuously variable over a range by rotation of a knob. Unlike more conventional arrangements, the back rest motion is completely linked to the knob rotation and does not rely upon friction to hold position. A toothed rack in the form of a U profile with teeth on either side is pinned to a support bracket rigidly coupled to the base of the seat. Two separate retaining plates mesh with the teeth on the rack. The retaining plates are eccentrically mounted on a shaft containing the adjusting knob. The eccentrics are so arranged that when the knob is rotated, one retaining plate changes the angle of inclination while the other prevents any slippage.

Title: Adjustable stator blade diffuser for centrifugal compressor - has hollow blades with one resilient wall and pressurising means
Inventor: KOTZUR JOACHIM
IPC: F04D27/02
Filed: 1974-04-03
Abstract: The diffusor has an adjustable cross-sectional flow area. Each hollow stator blade is provided with a resilient wall on the side which is at the shortest distance from the entry side of the adjacent blade and with an inlet orifice for a pressurised fluid. The resilient wall may be spring-loaded to return to its un-deformed condition. The internal pressure in the hollow blade may be controlled as a function of the position of the pre-swirl blades. An advantage, is the fact that separate sealing elements are not essential, since the common control of the diffusor cross-sectional area provides static sealing against the pressure medium.
