IPC: G01N21/31
Filed: 1978-02-14
Abstract: An apparatus for generating an atomic mist or an atomic cloud has a housing (38) arranged in which there is at least one cathode (12, 14) and an anode (16). Also present are ducts (50) or gas-guiding devices to generate a gas stream which is directed away from the discharge surface of the cathode (12, 14) or across said discharge surface. If a suitable potential is applied between the anode (16) and the cathode (12, 14), a glow discharge is produced between the anode and the cathode. The gas flow draws the atoms knocked out of the cathode discharge surface away from the cathode into a region beyond the cathode glow zone, thus generating an atomic mist which has a low level of self-radiation. The apparatus can be used for spectroscopic analyses of substances, employing fluorescence techniques. <IMAGE>

Title: Floating apron for controlling evapn. in storage tanks - is mfd. from corrosion resistant, non-submersible, impermeable modules with foam plastic core in plastic-covered flexible metal envelope
Inventor: SANDBORN EDMUND BERTIL
IPC: B65D88/36
Filed: 1979-01-04
Abstract: A modular structure for making a floating apron to control the evapn. of a liq. in a storage tank comprises a core made of foam plastic e.g. polyurethane and an envelope. The envelope encloses the core and forms a barrier which prevents the core absorbing liq. or vapour. It consists of a layer of flexible metal which is a good conductor of electricity, entirely covered with an outer layer of plastic material to prevent corrosion of the metal by the stored material. This metallic part can be fitted with an inner layer of plastic material to increase adherence between the core and the metal. It is preferable however to treat this inner layer e.g. by flame treatment to ensure liaison between the core and the coating. Problems associated with absorption of liq. by the polyurethane, corrosion of the metal layer, sinking of the apron and diminishing of rigidity are avoided. The floating apron made from the modules according to the invention cannot be attacked by the contents of the tank, cannot be submerged and is impermeable to liquids or vapours, while being economical and simple to install.

Title: Phase setting circuit for receiver clock pulse signals - has timer, triggered by each zero passage of data signal and transmitting data signal after each specified time period
Inventor: BURGER ERICH
IPC: H04L27/22
Filed: 1979-01-31
Abstract: Carrier signals phase-or phase difference-modulated are used as data signals for data transmission at high velocities. For this purpose a circuit for phase setting of clock pulse signals, generated in the receiver, contains a frequency dividere using a constant factor on the follower frequency of clock pulses and generating the respective clock pulse signals. Each zero passage of the data signals triggers a time element which transmits a time signal after each given time period. This time period is slightly smaller than the half period of the carrier signals generated on the transmission side. Switching elements transmit a resetting pulse for the frequency divider adjustment, this transmission taking place after each first zero passage of the data signals, following the zero passage triggering the time element. The switching elements preferably contain two flip-flops, the first one assuming the preset state during the zero passages after its resetting. The second flip-flop is set after the first one, being reset at once by higher follower frequency clock pulses.
