Title: Grid electrode prodn. for electron tubes - uses laser beam for grid formation in graphite body and system removing plasma flare in laser beam impingement point
Inventor: KRAFT HEINZ-PETER DIPL PHYS
IPC: H01J9/14
Filed: 1977-12-16
Abstract: The grid electrodes are of pyrolytic graphite which is deposited on a mandrel from a carbon containing gases in a thermal decomposition process. The blank thus formed is subjected to laser beam treatment to obtain the grid forming apertures. In the impingement point of the laser beam is formed a plasma flare which is removed from the working point by a gas jet, or by an external magnetic field. This process removes an obstacle of using temperatures for direct gasifying of graphite by the possibility of removing the plasma flare.

Title: Vacuum cleaner electric connection between body and nozzle - has connectors arranged to fit together when joining up coupling members
Inventor: WOERWAG EBERHARD
IPC: A47L9/28
Filed: 1977-12-24
Abstract: The end nozzle (10) which is driven by an electric motor is connected by a first connector (13) e.g. plug, to a second connector (3) e.g. socket, on the main body wherein the connectors are provided in the area of the coupling members (2, 11) where they can be detachably fitted together. Thus when the coupling members of the nozzle and main body are connected together the connectors automatically come into the contact position at the same time so that no additional manipulations are required. Since the connectors are only a short distance from the nozzle only a relatively short piece of cable (15) is left free on the outside of the cleaner.

Title: Gasifier or aerator for liquid tank - has vertical shaft with impeller at bottom and cone above impeller
Inventor: STELZER EKKEHARD DIPL PHYS DR
IPC: C02F3/20
Filed: 1978-05-30
Abstract: A gasifying or aeration appts. comprises a drive motor mounted above the liquid surface, with a shaft passing down from the rotor vertically through a suction pipe and carrying at its lower end a disc-type impeller with blades on its upper face. This impeller is just below the lower end of the suction pipe and the overall dia. of the blades is slightly greater than that of the pipe. At the connecting region between the drive shaft and the impeller is downwardly diverging (typically conical) gas guide block, which is pref. secured to the drive shaft and/or to the impeller. This guide block pref. projects with its lower end beyond the bottom of the suction pipe. The effect of the gas guide block is to ensure that the air or gas is fed to the impeller in a narrow annular region where the impeller speed is uniform. This results in highly effective breaking up of the gas bubbles and thorough mixing with the liquid in the tank.

Title: Excitation circuit for DC electromagnet - has series connected resistor for reducing attractive force, with capacitor in parallel
Inventor: SCHMIDT MANFRED
IPC: H01F7/18
Filed: 1978-08-09
Abstract: The holding force of the d.c. electromagnet is reduced after a preset period to a defined ratio of its attractive force by a series-connected resistor (2), behind which is a parallel connected capacitor (1). Preferably the capacitor and resistor, and possibly a bridge rectifier are assembled to form a four-pole module. The typical application is for electromagnetic valves whose coils generate a considerable amount of heat. This disadvantage is removed by the reduction of current, produced by the incorporated resistor so that the controlled liquid is not heated by the hot valve coil.

Patent DE-2910511-A1 (DE)
Inventor: KOENIG HELMUT DR ING
IPC: B61L17/02
Filed: 1979-03-16
Abstract: It is important for the control of rail brakes in railway shunting systems to know the brake deceleration acting on the vehicles handled in the brakes because the value of this brake deceleration is of decisive significance for determining a derivative release action which takes into account the reaction time of the brake when releasing it. This value cannot be detected by means of a radar signal because radar signals are too unstable. According to the invention, a reference speed is predetermined for each section in the brake. By means of brake force corrections with respect to a previously determined reference braking force, the actual speed curve of the sections is matched, whilst maintaining an adequate control stability, to the curve of the reference speed in such a way that both proceed in parallel, offset in time to a greater or lesser degree. Then, in fact, the braking force which is actually acting on the section is of exactly the same size as the reference braking delay taken into account for the specification of the reference speed, and the derivative release action can be determined exactly.
