Title: Superconducting niobium-tin thin film prodn. for HF applications - by reactive vapour deposition at controlled growth rate, ensures good surface quality
Inventor: ZIEGLER GUENTHER DIPL PHYS DR
IPC: H01P11/00
Filed: 1977-12-08
Abstract: Prodn. of a superconducting Nb3Sn film on a Nb surface for h.f. applications involves heating the Nb surface with a Sn source in an evacuated reactor, so that the Sn diffuses into the Nb surface, a film with a thickness of 0.1-0.4 mu, being produced by adjusting the Sn vapour pressure to give a growth rate of min. 0.05 mu m/h and pref. max 0.3 mu m/h. The prodn. of a very thin Nb3Sn film ensures that the good surface qualities of the Nb substrate are transferred to the film and subsequent surface treatment is made superfluous. Superconductors of this type are useful at frequencies of ca. 10 MHz and more, esp. as resonators and separators for particle accelerators or h.f. resonators for other purposes, e.g. frequency standards or esp. hollow cavity resonators or resonator coils.

Title: Multistage catalytic naphtha reforming process - without added or recycle hydrogen
Inventor: PEER ROGER LYNN
IPC: C10G35/12
Filed: 1978-01-16
Abstract: A multistage process for the reforming of naphtha feeds in the presence of a catalyst comprising a Gp. VIII noble metal on an alumina carrier to produce a gasoline fraction of increased actane number. Specifically, the feed is reacted in the absence of added or recycle H2, counter currently in a plurality of reaction zones through all of which the catalyst particles flow downwardly via gravity flow. The feed is reacted serially in the reaction zones in the order of increased catalyst loading, the product ultimately being recovered from the effluent of the reactive zone into which fresh or regenerated catalyst is introduced and which contains the greatest quantity of catalyst. Catalyst particles are transferred from one reaction zone to another in the order of decreasing catalyst loading and are ultimately being withdrawn from the system through the zone contg. the least amt. of catalyst. Compressive H2 recycle is eliminated and thus significant energy savings are obtd.

Patent DE-2818214-A1 (DE)
Title: Hollow fibres rinsing system - using a chloro-fluorohydrocarbon and air drying
Inventor: HEILMANN KLAUS
IPC: B01D67/00
Filed: 1978-04-26
Abstract: Non-water soluble liquids which adhere to the inside of hollow fibres, to be used for artificial kidneys, from the process of mfr., have to be removed very thoroughly. This is done by rinsing with a low-boiling fluorochlorohydrocarbon, followed by air drying at room temp. or =50 degrees C. The drying temp. is now low enough not to affect the filtration and diffusion properties of the fibre walls. The rinsing liq. can be easily reconditioned by distn. and any residual traces have a better biological compatibility than alcohol. The hollow fibres are laid in the housing of the artificial kidney through which a chlorofluorocarbon is circulated. The preferred fluid is a 3-chloro-3-fluoro-ethane. After completion of this phase, air of max. 50 degrees C is blown through or the rinsing fluid is evaporated by applying a vacuum. This is specially suitable for fibres which are less sensitive to drying out.

Title: Counterflow heat and mass exchange appts. - with gas flow split into several side streams contacting liquid flow
Inventor: CHEKHOV OLEG SINANOVITSCH
IPC: F28C3/06
Filed: 1978-05-16
Abstract: A distribution system for heat and mass exchange columns, based on the counterflow principle, has been worked out for two components one of which is a gas and the other a liquid. The gas flow is subdivided into (three) side streams each of which is brought into contact with the liquid in its turn. The emerging gas side streams are then joined up again. This removes the necessity for extreme precision in the ratio of the gas and liquid flows. The greater possible aggregate liquid/gas ratios and gas velocities in the reaction zones lead to smaller overall dimensions of the appts.

Title: Potential-free HV switching measurer - uses electro-optic coupler driven by voltage modulated frequency provided by analogue memory via optic fibre
Inventor: BECK HANS-PETER DIPL ING
IPC: G01R15/22
Filed: 1978-06-24
Abstract: The circuit makes potential-free measurements of h.v. switching processes. A control unit triggers both a thyristor through an electro-optic coupler and an oscilloscope. The thyristor voltage is tapped through a voltage divider by a sample and hold amplifier. The output passes through an analogue multiplexer, a voltage-frequency converter, an electro-optic coupler and a frequency-voltage converter to the oscilloscope. This procedure avoids measurement errors due to non-linearity, temp. effects and insufficient electro-optic band-width which appear in systems without modulation.

Patent DE-2846134-A1 (DE)
Inventor: ARX HANS VON
IPC: G01R19/15
Filed: 1978-10-23
Abstract: In the circuit arrangement, the current of the load is monitored by measuring the voltage drop across a resistor located in series with the load. In this arrangement, the voltage drop dependent on the operation state of the load (V) controls a switching element ((T) which actuates a monitoring member (M). To keep the voltage drop low and/or constant with a variable load current, a one-way or two-way semiconductor element (D1-D4) is provided as resistor. This saves additional circuit complexity. <IMAGE>
