Title: Rotatory evaporator for delicately handling liquids - has monitors ensuring optimal working with minimal consumption of cooling water
Inventor: SCHILTER MAX
IPC: B01D3/08
Filed: 1977-01-11
Abstract: Economies are effected in the volume of water necessary to cool the condenser of a rotatory evaporator. Coolant is only fed to the condenser when the rotatory drive and/or the heating arrangement are switched on; the coolant feed being cut off, when the drive and/or the heater are switched off. A solenoid controlled valve is fitted in the cooling water supply system of a rotatory evaporator having an electrical drive for the vaporising flask and/or an electrical heater, as well as a condenser connected to the vaporising flask. Connections from the drive and/or the heater to the valve solenoid act so that when the drive and/or the heater operate, the valve is open. The valve solenoid is connected in parallel to the supply for the drive and/or the heater, and a monitor in the circuit may be used to detect a flow of current to the drive and/or heater. Reduces to a minimum the amount of cooling water required whilst ensuring optimal working of the condenser without risk of damage or the necessity of expensive measuring devices.

Title: Purificn. of gas contg. sulphur di:oxide by washing - using an additive contg. a poly:carboxylic acid
Inventor: HOELTER HEINZ
IPC: B01D53/50
Filed: 1977-02-24
Abstract: In the purificn. of gas contg. SO2, the gas is brought into contact with a washing liq. contg. a strong mineral acid, partic. HCl, and circulating in a closed circuit, to which are added the carbonate and/or oxide and/or hydroxide and/or appropriate cpds. of Ca, the Ca ions in soln. fixing the SO2 during the washing. An additive contg. a polycarboxylic acid and if necessary a strong mineral acid, partic. HCl, are added to the closed circuit. The calcium-sulphur cpds. formed are oxidised into CaSO4 and removed from the system. The apparatus used for the process consists of a gas washer and an oxidn. appts. contg. several interconnected compartments including an oxidn. zone with an intake of air, a reaction zone with an intake of lime or lime-wash, and a zone in which the CaSO4 formed falls onto a conveyor and from which the clear washing liq. is pumped back to the gas washer. The amt. of washing liq. required to purify a given vol. of gas is lower than in previous processes, resulting in lower process costs.

Title: Monitoring of meat mincing operations - by continuous measurement of electrical conductivity of emulsion
Inventor: FEUERHERD ARNO
IPC: A22C17/00
Filed: 1977-03-15
Abstract: The conversion of meat products into minced meat can be supervised by an electrical method which eliminates the waste if the mincing continues longer than the optimum time, enables unskilled personnel to be used and makes the prodn. independent of seasonal temp. fluctuations. Two electrodes are arranged at a static spot in the cutter so that they are in constant contact with the emulsion. The conductivity of the emulsion is constantly measured by a conventional method. The empirically determined conductivity for the optimum point when the emulsion has the best stability is a sign that the mincing process should be terminated.

Title: Regular rhombohedric crystalline sodium percarbonate - obtd. by addn. of conc. hydrogen peroxide to decahydrate suspension with polycarboxylic polymer present
Inventor: MALAFOSSE JEAN
IPC: C01B15/10
Filed: 1977-05-25
Abstract: Prepn. of Na2CO3.1.5H2O2 in the form of regular rhombohedric crystals comprises reacting conc. H2O2 with a fluid suspension of Na2CO3.10H2O in a satd. soln. of Na2CO3 Decahydrate is in the form of at least partly, regular rhombohidric crystals and is used in an amt. such that the heat of dissolution balances the heat of crystallisation or the formation of the percarbonate and the other phenomena consume the heat prod., in the presence of a crystallisation modifying polycarboxylate polymer. Pref. 0.2-0.8 wt. % of sulphate ions are present during the decahydrate crystallisation. The suspension may be prepd. by dissolution of anhydrous solid Na2CO3 in the mother-liquor form a percarbonate crystallisation at >=37-38 degrees C, cooling to =32 degrees C lowering to a temp. such the 15-40 % of solid phase is present. The mother liq. pref. contains 1.5-2% NaCl. Suitable crystallisation modifiers are copolymers of maleic anhydride or maleic or fumaric acids with ethylene, propylene isobutylene, styrene, the vinyl ether or furan pref. as 0.01-1 g. per mole of Na2CO3.esp. 0.03-0.1 g. Process avoids the tendency for the percarbonate to adhere to cold surfaces and the need to add stabilisers. The process gives high yields due to efficient heat-exchanging. The prod. is easily cast.

Title: Growing diamond crystals by ion bombardment - of heated seed crystal in vacuo, opt. with dopants
Inventor: NELSON RICHARD STUART
IPC: C01B31/06
Filed: 1977-06-08
Abstract: A diamond crystal is grown by bombarding a diamond with a flow of carbon ions having an energy high enough to penetrate the crystal and produce mainly internal growth, in a vacuum. The diamond crystal may be doped with e.g. B and/or P atoms in controlled amounts to produce a semiconductor, and esp. to form a pn junction device. Doping with other ions may be carried out to colour the diamond. Internal growth permits the external surface to be irregular or even contaminated without serious defect to the body being produced.

Title: Under-roof heat insulating panel profiling - has spaces between ribbed attachments for rear ventilation
Inventor: HELFRECHT MANFRED
IPC: E04B7/22
Filed: 1977-07-29
Abstract: The profiling for hanging roof-covering panels in position, on a heat-insulating panel for an under-roof, is made up from attachments protruding at a short interval apart across the adjacent insulating panel surface; these combine to form a rib-type fitting batten.
