Title: Rechargeable radio-technetium generator - using column of activated chromatographic alumina and molybdate charging soln.
Inventor: LINDENBLAD GORDON E
IPC: G21G1/04
Filed: 1978-02-17
Abstract: Consecutive charging, elution and recharging of a Tc-99m generator involves the use of a column of activated chromatographic Al oxide. A charging soln. contg. a molybdate salt contg. mo-99 is passed through the column, so that molybdate ions are adsorbed. The column is eluted to give an eluate contg. Tc-99m in the form of pertechnetate ions and elution is repeated periodically until the activity of the eluate has dropped below the desired value. The entire charging and elution process is then repeated in situ many times. Tc-99m, esp. in the form of Na pertechnetate in sterile physiological NaCl soln., free from pyrogens, is valuable in diagnostics, on account of its organ specficty and min. physiological hazard due to its short half-life period. Only one generator is needed and this can be recharged in situ, whereas the usual system involves the weekly prodn. of fresh generators, a month before they are required.

Title: Industrial smoothing iron installation - has temp. regulator remote from iron making possible use of electronic circuits
Inventor: DOKOUPIL JIRI DIPL ING
IPC: D06F75/26
Filed: 1978-05-26
Abstract: The temp. detector positioned in the sole plate of an industrial smoothing iron consists of an NTC resistance, and is connected to a temp. regulating device arranged completely separately from the iron and connected to the power supply.

Inventor: MATENTZOGLU NICOLAUS DIPL ING
IPC: G21C1/07
Filed: 1978-09-04
Abstract: A gas circuit for a high temp. reactor comprising a pebble bed or similar core resting on blocks of high temperature-resistant material, where the gas can flow both horizontally and vertically through this supporting block assembly, possesses the following features. The flow path for the primary coolant gas from the reactor to adjacent heat exchangers, turbines etc., comprises numerous polygonal blocks; these blocks contain ducts for the gas; the ducts make an angle with adjacent ducts; the ducts connect with adjacent ducts or with ducts of adjacent blocks.

By thoroughly mixing the hot gas as it flows through numerous interlinked ducts, temp. peaks are avoided and there is no risk of hot spocts either in the reactor support structure or in the plant items supplied with the prim. coolant.
Patent DE-2838816-A1 (DE)
Inventor: PARRAS KARLHEINZ DIPL ING
IPC: H04L25/00
Filed: 1978-09-06
Abstract: A data transmission path comprises a first and a second station, a first data transmission channel operative for synchronously transmitting data from the first to the second station in synchronism with a predetermined clocking schedule and at a respective first maximum data transmission rate, and a second data transmission channel for asynchronously transmitting data from the second to the first station at a respective second maximum data transmission rate, the first maximum data transmission rate being equal to a multiple p of the second maximum data transmission rate. A test waveform is applied to the first station for transmission to the second station along the first data transmission channel, the test waveform presenting a data transmission rate at least approximately equal to said first maximum data transmission rate. The test waveform, as received at the second station, is applied to a selector circuit whose output waveform is applied to the transmitting input of the second station for transmission back to the first station along the second channel. The selector circuit transmits to its output only every p-th one of the waveform elements applied to its input, relying on clock signals which the second station produces one per waveform element of the synchronously transmitted test waveform. The shortest waveform-element duration of the waveform produced at the output of the selector circuit at least approximately corresponds to said second maximum data transmission rate.
