Patent DE-2627231-A1 (DE)
Inventor: MUELLNER JOHANNES DIPL ING DR
IPC: C12M1/04
Filed: 1976-06-18
Abstract: In order to treat a liquid with a fluid, the liquid is fed via a contact point with the fluid to a down duct (2) where the fluid, owing to its low density and the buoyancy resulting therefrom flows somewhat slower, as a result of which the contact time is increased. So as to avoid edge perturbations, the fluid is introduced via tubules (3) across the edge zone into the flow (11). The fluid and the liquid, after this contact has been achieved, are collected separately and brought into contact at least one more time in adjacent stages. The stages in their entirety may be traversed by the fluid and the liquid in parallel flow or in countercurrent, each individual stage being traversed in parallel flow. The invention can be used in gas admixture and aeration processes, as well as in biological submerged processes such as the production of citric acid or yeast. <IMAGE>

Title: Moisture determn. in foundry sand - in which sample is compacted under standard conditions before using electrical test circuit
Inventor: KIRCHNER KARL
IPC: G01N27/04
Filed: 1976-06-22
Abstract: The moisture content is determined of powdered- or granular-material, esp. foundry sand, with the aid of electric-currents and/or -fields, or by nuclear radiation. From a batch or a continuous stream of the sand, a sample of predetermined size is taken; the sample is compressed in a prescribed, uniform manner using a specific pressure, and then the moisture content is determined. Pref. the press. and mould employed to make a conventional sample for determn. of the compression-, tensile-, or shear-strength, permeability, etc. are used. Alternatively, various mechanical devices are used to isolate a sample of sand from a moving stream or in a hopper; a pneumatic cylinder is then employed to compress the sample in a standard manner, followed by determining the moisture content, in most cases via a pair of electrodes connected in a test circuit. The samples are compacted under standard, identical conditions so the test results are independent of the packing density; and the moisture content of reclaimed sand can be accurately adjusted.

Title: Photocopier data transmission system - for teleprinters automatically prevents double connection of sub units
Inventor: THORNTON DOUGLAS R
IPC: H04L12/407
Filed: 1976-08-17
Abstract: A teleprinter data transmission system using a photocopier is arranged so that any subunit connected to the line (to e.g. a central processor) automatically prevents another subunit from being connected. If two subunits attempt to make a connection simultaneously, the entire process is broken off and re-started. Two detectors monitor the line and detect two different line conditions, both differing from the line free condition. Switching circuits indicate when a subunit wants a connection to the line and control the connection devices that make this connection. The switching process is modified or blocked when certain signals appear simultaneously.
