Title: Petroleum ether extracts sepn - using a vessel with float operated outlet ports to retain ether layer
Inventor: RADEMACHER HORST
IPC: E03F5/16
Filed: 1973-08-07
Abstract: Aq. systems which have been extracted using a petroleum ether or other immiscible solvent can be sepd. from the light ether layer in a horizontal separator in which the ether/water mixt. is fed from a feed channel via a series of vertical slots. The water is discharged into a duct via a series of circular outles, controlled by float operated flap valves which are buoyant in water but not ether. As the water level falls these outlets successively close. The ether layer together with a residual water sludge layer is then extracted into the outlet chamber. The separator allows for parallel flow throughout the length of the system but is not dependent on residence time. Thus whatever the flow of water or ether or their proportions, ether will not escape into the water outlet chamber. This is particularly important if there is an accident and excess oil or ether is spilled. Used generally for oil/water systems. etc.

Title: Conversion of phase-modulated photographic data - is into amplitude-modulated data using data input superposed by grid
Inventor: ROTTENKOLBER HANS DR ING
IPC: G02B27/44
Filed: 1973-08-23
Abstract: The data input into the data carrier in phase structure by exposure is superposed by a grid applied before, on or after exposure in phase structure.

Title: Uniform speed haulage for HF coaxial cable - uses linear electromotor with cable hauling disc fixed on rotor
Inventor: SCHATZ FRIEDRICH
IPC: H01B13/00
Filed: 1973-09-10
Abstract: The haulage arrangement, for HF coaxial cable in manufacture, guiding the cable with uniform velocity through the different processing stages uses an electromotor driven rotatable circular iron disc around the circumference of which the cable is looped. The driving electromotor is at least one linear electromotor the rotor of which is fixed to the disc. The rotor is a ring shaped rail of aluminium or copper and the stator is arranged directly opposite to the rotor rail. The ring shaped rail may radial or axial jut out of the disc and the stators of linear motors may be placed to both sides of it. In order to achieve very low revolution an asynchronous motor may be used. By appropriate choice of the rotor the linear motor may be a synchronous motor or a dc-motor. The arrangement secures uniform rotation of the hauling disc, uniform transport of the cable and so avoids diameter variations of the HF coaxial cable.

Title: Burglar alarm system based on seismic principles - processes signals to ensure they lie within given amplitude and frequency windows before raising alarm
Inventor: DEHNERT HEINZ DIPL PHYS
IPC: G08B13/16
Filed: 1974-08-08
Abstract: The seismic transducer consists of a rod attached rigidly to a heavy mass with an amplifying arrangement for detecting signals. These signals are then processed to ensure that they fall within one or more "windows". An amplitude window protects against noises made by hailstones or cars and trains. A frequency window may also be applied and there is a time window between individual pulses lying within the other two windows. A logic network comprising stores (12, 15) and comparators (13, 14) and an "and" gate (16) ensures that an alarm is only triggered if a signal lies within all these windows. A further check involves monitoring the difference between signals received at two receivers placed at a given distance apart. A subtractor (17), store (12) and comparator (13) are required in this case.
