Title: Prodn. of naturally cloudy fruit and vegetable juice - by comminution, immediate sepn. of insol. fruit flesh and juice in centrifuge and inactivation of pectolytic enzymes
Inventor: NAGEL BERND DIPL ING
IPC: A23L2/02
Filed: 1991-07-09
Abstract: In prodn. of naturally cloudy fruit and vegetable juices, where a mash of comminuted fruit is sepd. in a solid jacket screw centrifuge into fruit flesh and juice, the sepn. of insol. fruit flesh with the centrifuge takes place immediately after the comminution of the fruit, and immediately after that pectolytic enzymes and polyphenol oxidases proper to the fruit are inactivated by heating the juice leaving the centrifuge. Pref. the fruit is ground to a mash with grain size not above 5mm (3mm). The insol. fruit flesh is sepd. in the centrifuge under a protective gas, and there may be continuously degasing between sepn. of the insol. fruit flesh and the heating, or during the heating of the juice. To obtain optimum stability of turbidity, fruits with about 2 g/kg of water-sol. pectins are processed. The cloudiness content and the particle size of the turbid matter are adjusted to the required value after heating, by means of a plate centrifuge, pref. a self-emptying centrifuge, opt. with a pre-connected homogeniser. The naturally cloudy fruit and vegetable juices are clarified by enzyme treatment and pressing techniques, e.g. fining and filtration to give clear non-oxidised prods. ADVANTAGE - Enzymatic alteration of the components of the fruit is avoided. Pressing takes only a few secs. so that no enzymatic breakdown of rebuilding reactions occur. the efficiency of the centrifuge is raised. Very fine comminution of the fruit is not necessary, and harder prods. e.g. apples and carrots can be ground to about 3mm. The prods. have optimum stability of cloudiness and are free from oxidised components of the fruit.

Title: Dry cooling of coke or other bulk material - by circulating gas in system with rough and fine dust freeing with utilisation of heat content of dust
IPC: F27D15/02
Filed: 1991-11-05
Abstract: Method, is partic for coke dry-cooling, for cooling hot bulk material in a cooling vessel by means of a circulating cooling-gas. Material is first roughly dust-freed by the gas fed through, then cooled in a re-cooling plant, and possibly after a fine dust-freeing in a fine separator it is returned to the cooling vessel by a blower. Dust sepd. in the rough separator goes to a bed supplied with cooled cooling-gas. Coarse dust is drawn from the bed, and the collin gas heated by the dust in the bed, possibly together with fine dust, is fed into the hot cooling-gas flow and so into the re-cooling plant. USE/ADVANTAGE - Coarse particles are, by simple means, removed from the cooling-gas and cooled before the gas is fed to the re-cooling plant. Heat content of the removed coarse dust can then be used simply. Protection of plant (e.g. a waste-heat boiler) from erosion by coase particles is ensured.

Filed: 1991-12-28
Abstract: The hydraulic control device for rotating the camshaft (10) of an internal combustion engine has a central body (11) which bears the sprocket (18) driven by the crankshaft. Between the central body and the sprocket there is a coupling member (12) having helical gearing (13, 14) on its outer and inner peripheries which engages with identical helical gearing (15, 16) on the central body and the sprocket. A fluid pressure generated by a radial piston pump (26) acts on the coupling member from at least one side. The radial piston pump has a stator (27) fitted on the central body which contains pistons (30) in piston bores, the outer caps of which bear on a bearing race in the eccentric broadening (25) of the sprocket. When the coupling member is moved, the aforementioned helical gearing alters the relative angular position of the camshaft (10) and the sprocket (18), thus altering the opening and closing times of the internal combustion engine valves.

Inventor: DEECKE LOTHAR
IPC: G01S3/28
Filed: 1992-07-17
Abstract: Firstly, direction components are generated and normalised in respect of their amplitudes as normalised bearing components (xi,yi). A sum vector (vector LSigma) is formed from the components (xi,yi). The sum vector (vector LSigma) is normalised w.r.t. a maximal value to a quality number (Q).
