Title: Float flowmeter - float position measured by sound waves emitted by fixed sender and reflected from float
Inventor: OBERMOSER KARL
IPC: G01S15/12
Filed: 1974-06-06
Abstract: In a flowmeter which uses reflected sound, the propagation time of the sound wave is measured. Emission of periodic sound pulses is controlled by a tripping signal, whose period is readjusted every time by a tuning signal whose value depends on the sound pulse propagation time, so that after a few periods the sound pulse propagation time from sender to the float and back is synchronised with the tripping signal period. The tuning signal amplitude is used for the flat position indication. An electric tripping signal employed is an a.c. voltage or current signal, or a triangular oscillation.

Title: Method fo propulsion using oscillators and barrier members - involves producing high frequency current using ultrasonically-controlled rectifiers
Inventor: HANSCHMANN HORST
IPC: F03H1/00
Filed: 1974-06-28
Abstract: In a method of propulsion with the aid of two, three or more opposed or cardanically arranged electromagnetic fields in which ions and electrons are accelerated many thousand times per sec. in order to produce strong repulsion forces without the need for high orbital velocities, the necessary high currents to feed the self-induction coils are obtained from a unit having two rectifiers, such as would be used in power stations, which are controlled by an ultrasonic oscillator such as a magnetostrictive unit with or without capacitor switching. The high intensity and high frequency currents align the electron orbitals in crystalline materials and bring them up to a higher energy level which is sufficient to cut off or superimpose its effect on one direction of gravitational waves or other electromagnetic radiation.

Title: Door holder for motor vehicles - has bracket trapped by flexible roller when door is open
Inventor: ECKL ALBERT
IPC: E05D11/10
Filed: 1974-07-25
Abstract: The door holding mechanism is used in motor vehicles for holding the door open in its extreme end position. This mechanism is used especially in agricultural tractors and building site machines which work under unfavourable conditions. A U-shaped bracket made from a round bar is pivoted on the door hinge pivot (16). The free ends of this bracket are welded on a plate (4) which is connected to the door hinge. On full opening of the door the transverse part of this bracket comes into contact with the flexible cylinder (9) held on a shaft in a frame with baseplate (5) and plates (6). This block efficiently traps the bracket and hence the door is firmly held.

Title: Vacuum cct breaker with axial magnetic field generating contacts - has contacts in evacuated insulating sleeve defining light arc path
Inventor: KIMBLIN CLIVE W
IPC: H01H33/66
Filed: 1975-06-19
Abstract: The vacuum circuit breaker has two contacts in a highly evacuated tubular, insulating sleeve, one being movable relative to the other between the contacts make and break positions. In the break position the contacts limit a light arc path. The stationary contact is of such design the current flowing through the same, when the light arc has been struck, generates a magnetic force, tending to move the light arc in an annular arc path in a present circumferential direction. The moving contact design permits the generation of a magnetic force, under the same conditions, which tends to move the light arc in an opposite direction.

Abstract: In the parent patent, cables or tubes or solid bars are coated with synthetic thermoplastic materials which may be foamed or elastomers using extruding machines in which the coating material is not cross-linked or vulcanised and acted upon prior to exit from the machine by impact and/or torsional forces. In this addn., material moving in the direction of exit from the machine is subjected to additional axial forces acting in the exit direction at the location where the material is exposed to the impact and/or torsional forces. Coating material is prevented from moving in the reverse axial direction to set in gaps between stationary and rotary extruder members.
