Patent DE-2356156-A1 (DE)
Title: Engine or muscle powered aircraft - has horizontally rotating air screws within pockets formed in wings
Inventor: LAUER ARNO
IPC: B64C31/04
Filed: 1973-11-09
Abstract: The aircraft is of lightweight construction which is based on lightweight materials such as plastics. The counter rotating rotors have blades whose attitude can be modified by rotating the blade about their tips and roots. The inclination of these blades generates forward drive or lift as required. These rotors rotate within pockets so that only part of the complete circular configuration is projected laterally from these pockets. A gap is arranged for outlet of air along the front edge of the aircraft body. The air entrained by the rotors is pressed into this gap and forced out under the aircraft body. This quantity of air is pushed backwards under the flat aircraft body and produces additional lift.

Title: Locking yoke for multiple animal pens - consists of two pivoting sections which open or close, connected to U-shaped piece for neck of animal
Inventor: HOERMANN RUDOLF
IPC: A01K1/06
Filed: 1973-11-20
Abstract: The multiple locking yoke extends over adjacent feeding-pens and ensures that the animals are collectively attached and detached in them. A cross bar over each pen is fastened to the uprights dividing each pen from the next, two-thirds of the way up. The cross-bar is U-shaped in the middle to go over the animal's neck. On each side of the U-shaped bar are pivoting elbow-shaped fittings attachments, consisting of a top and bottom arm, forming an obtuse angle where they join. The fittings are bolted to plates. The top arms are hinged to rods running parallel above the U-shaped bar. When the rods are moved in the contrary direction, they cause the attachments to move the bottom arms in an open or closed position. A lever which pivots on a horizontal axis at the top of the one upright of a pair operates the rods.

Title: Weighing method for charge of loose material - has high accuracy for industrial processes using mathematical coefficient addition process
Inventor: KUSCHEL KONRAD DIPL ING DR
IPC: G01G13/295
Filed: 1974-04-10
Abstract: Weight reading change with respect to time (dW/dt) is determined during the weighing process and subjected to several mathematical operations. Material flow is cut off when weight reading reaches a specified value. A first device determines the quotient (dW/Dt), and a second determines its square. A further device is connected to the first, in which the above quotient is multiplied by the closing time (tn). The second device is connected to a device in which (dW/Dt)2 is multiplied by a constant (C). Both multipliers are connected to a summation unit which adds the required weight (WS) to the negative value of tn (dW/dt) and to C(dW/dt)2. Finally the difference is produced between the weight reading and the above sum. When this difference becomes zero, a closing device is operated.

Title: Protection circuit for three-phase networks - has logic circuit comparing time sequence of binary signals for monitors to trigger protection
Inventor: BORN ECKHARD DIPL PHYS
IPC: H02H1/00

Title: TV receiver with line output stage - uses frequency different from line frequency for line output stage oscillations
Inventor: MUEHLMEYER FRANZ ING GRAD
IPC: H04N5/12
Filed: 1975-06-11
