Title: Catalytic hardening of sand cores or moulds in metal foundries - where hot air, which removes residual catalyst from hardened core, is reused in next hardening cycle
Inventor: MICHEL HORST-WERNER ING GRAD
IPC: B22C9/02
Filed: 1978-07-28
Abstract: The sand is mixed with binders which harden when exposed to a catalyst. A specific amt. or does of the liq. catalyst is vaporised and mixed with compressed air which carries the catalyst vapour through the sand core. Hot compressed air contg. no catalyst is then used to remove the residual catalyst from the core, the air and catalyst entering a sealed chamber in which air expands during the pause between successive core hardening cycles. The next dose of catalyst is then fed into the sealed chamber. and the mixt. of hot air and catalyst is used for the next core hardening cycle. The pref. appts. includes a catalyst vaporisation plant feeding a mixing chamber fed with hot air, a network of valves ensures the recycling of the residual catalyst. Each dose of catalyst is completely vaporised, but the total quantity of heat required by the hardening plant is reduced as compared with an earlier process proposed by the inventor.

Title: Delactosation of milk-based dispersions - by sepn. and enzymatic degradation of lactose and return of products to dispersion
Inventor: TUCHENHAGEN JUERGEN ING GRAD
IPC: A23C9/12
Filed: 1978-12-08
Abstract: Partial or total enzymatic degradation of a low-mol.-wt. substance (I), e.g. lactose, in an aq. polydisperse system contg. low- and high-mol. wt. substance (e.g. milk, whey or permeate) is carried out by (a) sepg. (I) and enzymatically degrading it without mixing the enzyme with the aq. polydisperse system, and (b) returning the degradation prods. to the aq. polydisperse system. The process is pref. carried out in a double tube arrangement in which the inner tube is permeable to (I) and impermeable to the enzyme. The enzyme is contained in (or passed through) the inner tube, and the aq. dispersion is contained in (or passed through) the space between the inner and outer tubes. The process avoids auto-inhibition due to build-up of degradation products and avoids attrition problems associated with the use of immobilised enzymes.

Title: Liquefying plant phosphatide(s) - by adding a re-esterified plant oil to the crude lecithin
Inventor: HEIDEMANN GUENTER DR
IPC: C07F9/10
Filed: 1979-04-18
Abstract: The prepn. of liq. plant phosphatides comprises liquifying crude lecithins by the addn. of 3-5% of a re-esterified plant oil. Lecithin is used as an additive for food stuffs, as an emulsifier, usually by a stirring or kneading process, as an additive in the paint and dyestuffs industry and as a wetting agent in the steel processing industry. In all these applications the high viscosity of commercially available crude lecithin is a disadvantage. This invention produces liq. lecithin of viscosity 8,000-12,000 cP (cf 20,000-25,000 cP for crude lecithin).

Title: Organic solvent recovery - uses waste water as coolant in the condensation stage
Inventor: SCHUIERER MANFRED
IPC: D06B23/20
Filed: 1980-01-19
Abstract: In the recovery of organic solvent, used with water for processing textiles, the waste water is used as a coolant for condensing the solvent. The warmed water is then cooled down by evaporation which increases its waste concentration. The waste water from the washing process is collected in a vessel and held to a minimum level to give a removable layer of heavier dirt particles at the base, giving diluted waste water available as a coolant, the bottom layer in the vessel giving a solids concentration of 30-60 per cent. The vessel has two sections, operating alternately, to adjust the dirt concentration in one while the other section takes in fresh waste water. A cooling tower is used for the evaporation and recooling of the waste water, where the waste water is sprayed through air, to bring its temp. down to about 20-40 deg.C, pref. to 25-35 deg.C. The recooled waste water is returned to the collecting vessel, and about 2-4 per cent is evaporated during the condensation/cooling cycle. The organic solvent is passed through an indirect heat exchange between the waste water and the solvent. The process allows the waste water to be used usefully, as it is available in the right volume and at a sufficiently low temp. for the purpose. It also has a relatively low dirt content, so that the concentration can be increased by evaporation on absorbing heat.

Title: Electrical adaptive control system - provides optimised regulator performance by comparison of regulator standard function with optimum transfer function
Inventor: MEYL KONSTANTIN DIPL ING
IPC: G05B13/02

Abstract: A regulator loop is optimised by comparison of a optimum transfer function with a standard transfer function. For an optimisation system based upon a standard function computer, a forward path contains an integrator operating with a feedback loop containing a time constant. A feed forward stage contains a second order element. The system operates for an unspecified system transfer function. PID regulator stages based upon operational amplifiers are used for alternative versions.

Title: Sepn. of molybdenum and vanadium by reactive ion exchange - where anion exchanger is treated with reducing agent so vanadate is removed as vanadyl salt soln
Inventor: NADLER HANS-GEORG DIPL CHEM DR
IPC: C01G31/00
Filed: 1980-02-12
Abstract: Either a liq. or a solid anion exchanger with a basic character is used to extract molybdate and vanadate ions from a soln. The vanadate ions on the exchanger are then reduced by an agent (I) to tetravalent vanadyl ions, which enter the aq. acid carrier phase of agent (I), leaving the molybdate on the exchanger. The molybdate is next removed by a known method of re-extn. or elution using a basic aq. soln. An aq. soln. at Ph 2, contg. 2.7g/l V and 3 g/l Mo, was fed at room temp. through an extn. column in counter-current to 2 litres of a liq. contg. by vol. 10% isodecanol, 10% diiso-tridecylamine, and 80% solvent naphtha-60. The organic amine phase then contained 13.4 g/l V and 15 g/l Mo, whereas the raffinate contained less than 0.01 g/l each of V and Mo. The pref. process uses either an inorganic anion exchanger in a lia. phase; or a solid organic anion exchange resin. The advantage is the winning of Mo and V from solns. contg. only a small amt. of these elements, and then their efficient sepn.
