Title: Determining electrically conducting fluid level - using oscillator circuit damped by resistance between immersed electrodes in water separator
Inventor: ROEDL PETER
IPC: G01F23/24
Filed: 1979-06-21
Abstract: A measuring arrangement for the level of an electrically conducting fluid, esp. for a water separator in a vehicle, prevents the formation of dangerous oxyhydrogen gas. It employs two electrodes (5,6) immersed in the liq.(4) but one suffices if the container (1) wall forms an electrode. The electrode circuit is connected in parallel with an electrical parallel oscillator circuit (7,8) whose stimulated oscillation is damped by the ohmic resistance between the electrodes. The degree of damping is z measure of the level of liq. in the container. When the level of water (4) separated from the fuel (3) is high enough to contact the electrodes a signal is triggered which opens a magnetically actuated valve (12) removing water from the tank. The amplitude of the oscillation may alternatively be visually displayed.

Patent DE-2939077-A1 (DE)
Inventor: NEY HERMANN DIPL PHYS
IPC: G10L15/00
Filed: 1979-09-27
Abstract: In order to reduce the information contents of a sound signal, for example a speech signal, the sound signal is divided into adjacent frequency ranges and the signals then obtained are consecutively integrated over short time intervals to short-time-spectrum signals. Subsequently, a histogram of the short-time-spectrum signals is formed for each frequency range and said histograms are divided into a given number of equal-area portions. The boundaries of said portions, which are referred to as quantiles, represent the characteristic values. The amplifier noise or the noise of the complete recording arrangement as well as a difference in sound energy level during when different sound signals are processed can then be eliminated at least in respect of their effect.

Patent DE-3028592-A1 (DE)
Title: Balancing of rotating workpieces by deposition welding - where metal wire is melted by electric resistance heating and driven by electrodynamic forces onto workpieces
Inventor: VARDANIAN ZAREG VAGEEVIC
IPC: B23K9/04
Filed: 1980-07-28
Abstract: The appts. has an iron core with an excitation coil; and the core forms an air gap with a pole made from two rotating disks. One disk is located eccentrically in the other; and each disk carries a circular row of rollers feeding a consumable welding wire into the air gap. When the wire enters the air gap, it closes the electric contacts of a power supply, which melts the end of the wire. Electrodynamic forces then fling the molten particles out of the air gap and onto the rotating workpiece. An out-of-balance sensor adjusts the electric current used to melt the wire, and thus the amt. of wire reaching the workpiece. The appts. does not use compressed air, so noise is reduced; and spring-loaded wire brushes keep the feeder rollers clean so the working life of the appts. between overhauls is increased. The feeder rollers are also spring loaded so wire of varying dia. can be melted.

Title: Feeder for tobacco lamina shredding machine - uses vibrating conveyors to cause lamina to settle and compact under own weight
Inventor: BRACKMANN WARREN ARTHUR
IPC: A24B7/14
Filed: 1980-12-15
Abstract: In a tobacco lamina shredding machine, the lamina are formed into a tobacco layer in which the lamina are horizontally oriented. The tobacco layer is precompacted without the use of any force other than gravity and vibration, and is fed to the cutting operation without any substantial change in lamina orientation. The resulting tobacco shreds have an increased filling power, allowing more economical production of cigarettes. The compaction of the tobacco is brought about by depositing the tobacco lamina layer on a vibrating conveyor, which subjects the lamina in the layer to vibrations which cause the lamina to settle and compact under their own weight.

IPC: G03B27/60
Filed: 1981-01-26
Abstract: A subpressure film holding plate for a process camera is specified, in which a base plate is connected in the middle to a suction tube. A perforated plate has a multiplicity of small subpressure openings. The base plate is fastened to the rear, and the perforated plate to the front, of a basic frame, so that these parts together specify a subpressure box. Corrugated plates are arranged lying in this subpressure box between the base plate and the perforated plate with a spacing such that there are formed between them main distributor ducts whose width gradually increases from the edges towards the centre of the base plate. The corrugations of the corrugated plates are arranged like frames concentrically with the centre of the base plate. Flattened head and foot sections of the corrugated plates bear against the base plate or the perforated plate. Pieces of flat film of different size can therefore be securely fixed on the film holding plate without adaptation.

Title: Process for the production of aluminium master alloys with metals having a high melting point
Inventor: SATTLER HANS-PETER DIPL ING DR
IPC: C22C1/02
Filed: 1981-03-10
Abstract: The invention relates to a process for the production of aluminium master alloys with one or more metals having a high melting point, such as Zr, Ti, Mo, Va, Cr, Mn, etc., by adding metals in the form of alkali metal fluoride compounds or as a mixture of metal fluoride compounds and alkali metal compounds in an aluminium melt. Various proposals have already been disclosed for the production of master alloys of aluminium with metals having a high melting point, but these proposals either operate with melting points which are too high or give a very poor yield of the alloy elements. In a process of this type, to achieve the object of converting, as far as possible without loss, the alloy elements added in the form of alkali metal fluoride compounds or as mixtures of metal fluoride compounds with alkali metal compounds, it is proposed to carry out the addition continuously during casting of the aluminium melt kept at the usual melting point, in an amount which corresponds to less than 110% of the theoretical content of the metals in the master alloy. Figure 1 shows the curve of the zirconium content for an AlZr master alloy as a function of the melting point and of the holding time of the melt after introduction of the zirconium compound. Figure 1 also shows micrographs of ground sections for some test points.
