The invention relates to a new method of preparing lactulose by basic isomerisation of lactose. According to the invention the reaction mixture is treated with hydrogen peroxide or sodium chlorite to obtain lactulose of an acceptable colour for a pharmaceutical product. Preferably 0.5 - 5 g of hydrogen peroxide are used per kg of lactose. 1H2O.

A dynamically balanced apparatus having a reciprocating member includes an eccentric shaft operatively connected to a motor output shaft, and a drive member operatively connecting the eccentric shaft to the reciprocating member for driving the reciprocating member upon rotation of the eccentric shaft. An eccentric flyweight is mounted on the output shaft to be rotatable therewith for canceling the...

The invention relates to a lighting unit for installation in a plane, in particular for airports, with the object of radiating light in an optimum manner in two opposite directions in an energy-saving way and with a minimum of electric power. It should be compact and its function should not be adversely affected during rough operations by snow-clearing equipment or the like; it has the following f...

Nach der Erfindung werden Schweißpatronen (6), mit denen Randprofile von Kunststoffabdichtungsbahnen (1, 2) in Erdschlitzen miteinander verschweißt werden, mit Flügeln (9) versehen, die in die Dichtfugen der Randprofile ragen und die Dichtflächen sauber räumen, so daß ein mit einer nachlaufenden Verdickung (8) erzeugter Materialpfropfen eine gute Verschweißung herbeiführen kann.; According to the ...

Zum Ummanteln länglicher Körper (9), wie z.B. Kabelbäume mit einem aus einer Schweißbahn (11) aus verschweißbarer Kunststoff-, Polster- oder Schaumstoff-Folie gebildeten Mantel (9.1), unabhängig von Querschnittsform und Durchmesser, werden ein Verfahren und eine Vorrichtung vorgeschlagen, mit der der längliche Körper (9) aus einer Position vor der vorhangähnlich gespannten Schweißbahn (11) quer zu...

For covering elongate objects (9), such as for example cable harnesses, with a coat (9.1) made of a weldable web (11) of a weldable sheet of plastic, padding or foam, irrespective of the cross-sectional shape and diameter, a process and an apparatus are proposed, by which the elongate object (9) is moved out of a position in front of the weldable web (11), which is stretched out in the manner of a...

Certain articles required to function in air at temperatures of 250 DEG C or higher comprise very fine particles of vermiculite from which the interstitial magnesium ions have been at least partially removed and which has been swollen in water. These articles are not ordinarily exposed to water when in use, but if they are they are likely to disintegrate quickly because of the ready dispersibility...

A patient-worn harness or vest (10) protects at-risk patients from the possibly fatal results of heart arrhythmias. The harness or vest incorporates sensing electrodes (22) for monitoring heart condition, a microprocessor (116) and memory (118) for processing signals received from the sensing electrodes and comparing same with patient's data, and skin-contacting pulsing electrodes (32) for applyin...

Components for semiconductor diffusion furnaces are constructed of a high purity impervious silicon carbide or silicon nitride matrix deposited on a pre-shaped fibrous matrix of silicon carbide, carbon, or carbon coated silicon carbide. The high purity of the matrix prevents undesired gaseous components from contaminating the atmosphere of the furnace, and the fibrous re-enforcement provides stren...

Copper-containing catalysts for low-temperature conversion at temperatures of from 150 to 300 DEG C and at from 10 to 40 bar which additionally contain aluminium, and zinc, if desired in the form of the compounds or oxides, and are prepared by joint precipitation, the copper-containing catalysts containing potassium and having a BET surface area matched to the potassium content, the potassium cont...

Dyed cotton garments are bleached by tumbling with an attrition-release bleaching agent comprising cemented aggregates of mineral particles with a particulate permanganate oxidizing agent distributed therein, the aggregates being in the form of solid pellets with abradable surfaces.

A reliable indication of temperature-compensated pressure is provided from each of the wheels of a vehicle to an operator within the vehicle. A piezoresistive transducer bridge (1) is supplied by a constant current source in one embodiment, and by a voltage of constant amplitude in another embodiment. Voltage to the bridge is reversed on a periodic basis. The use of constant current enables compen...

Growing of microorganisms takes place in a fermenter in which simultaneously products of metabolism are separated and withdrawn by microfiltration with the aid of a diaphragm filter, and a suspension of microorganisms is stirred in the fermenter in the region immediately surrounding the diaphragm filter.
