Patent DE-2702785-A1 (DE)
Title: Sepn. of gas mixt. by alternating pressure - using two carbon molecular sieves giving highly enriched products
Inventor: LEITGEB PAUL DR
IPC: B01D53/047
Filed: 1977-01-24
Abstract: A gas mixt. under pressure is sepd. into its constituents by passing it over a carbon molecular sieve which preferentially adsorbs >=1 component. A stream of gas enriched in the other component(s) is then drawn off, and before a fresh stream of gas is blown across th e sieve, it is regenerated. To release a flow of gas enriched in the adsorbed component(s), pressure above the sieve is reduced but is not allowed to fall below that of the atmos. The ratio between the adsorption pressure and the desorption pressure is 4 to 6. The ratio between the adsorption and the desorption pressure is 4 to 14. The ratio between adsorption and desorption pressure is ca. 20. Process has low energy consumption in nitrogen ext. from air, the product obtainable at a pressure of 4 bar and a residual content of O2 of 3 vol.% is 40%. At a pressure of 12 bar, the product of N2 with a 3 vol.% residual content of O2 is ca. 50%.

Title: Feedstuff rack for milking cows - incorporates lever which moves central vertical partition to trap animal's neck
Inventor: WEBER ADOLF
IPC: A01K1/06
Filed: 1977-03-21
Abstract: The hay-rack is positioned over the feeding trough and has a vertical partition. The hay rack is opening by a lever, thus trapping the cow and providing a corner for the animal to feed from. The hay rack has a vertical partition in the middle of the stall. The lever causes the rack to swing back towards the animal, leaving an opening for the cow. When the rack is moved back, the feeding corner serves as an area for metering out the feedstuff. The cow is held by the neck during milking, and cannot interfere with the milking operation.

Title: Conical corrugated vessel produced by spinning tube - uses set of small rollers to generate corrugations against conical mandrel
Inventor: NITSCHKE ACHIM ING GRAD
IPC: B21D22/14
Filed: 1977-05-20
Abstract: Conical vessels with a corrugated surface can be formed from metal tubes by spinning a mandrel of roughly conical shape with its surface conforming to the required corrugations. A number of rollers also with corrugated surfaces are equally spaced around the mandrel and with their axes inclined to the mandrel axis. A tube is fed into the gap between the mandrel and rollers from the larger end of the mandrel. The mandrel and rollers rotate in opposite directions and deform the tube, by spinning, into the required corrugated conical shape. An alternative method uses a set of small rollers with converging axes instead of the solid mandrel.

Title: Recovering mixed carbides from hard metal scrap - by successive treatments with nitric acid and alkali, followed by purificn.
Inventor: MEYER HORST
IPC: C22C29/00
Filed: 1977-06-14
Abstract: The scrap contains TaWTi-carbide, and/or NbWTi-carbide; and the binder metal Co or Ni is dissolved out by hot 10-30% HNO3, which also converts tungsten carbide (WC) not bonded in the mixed crystals into tungsten-oxide-hydrate, which is dissolved by alkali. The triple carbide residue is then purified by treatment with 5-10% HF. Instead of the HF purificn. treatment, the triple carbide residue may be carburised in vacuo at 1500-2000 degrees C. The HNO3 treatment for dissolving the Co or Ni is pref. carried out at 60-90 degrees C. Provides economic recovery of valuable triple carbides i.e. TaWTi- or NbWTi- carbides as pure, re-usable prods. sepd. from monocarbides such as WC.

Inventor: WAEGELE ROLF DR ING
IPC: C12N13/00
Filed: 1978-09-27
Abstract: The growth of vegetables, animal and bacterial cells and tissues is beneficially affected by applying to the root area or to media containing nutrients a direct current. The direct current is pref. either pulsating or has its polarity reversed at regular or irregular intervals. The d.c. voltage is preferably applied between two electrodes inserted in the soil. One electrode can be in the shape of a plate cover the bottom of the plant receptacle; the other is a rod inserted near the top. A still greater stimulation of the growth can be achieved if the soil near the roots is intermingled with nutrients of over 1 mu size in finely dispersed form. The electrodes should be chemically inert, without any catalytic effect, and non-toxic. This stimulates the growth and requires less power consumption than alternating bright/dark periods of illumination.
