Abstract: A method and an apparatus for incubating animal cells in an incubation tank of a mechanical stirring system, wherein a culture solution is stirred while restricting the disturbance of the liquid level and formation of vortex, and an oxygen-containing gas is continuously ejected from a blow nozzle towards the liquid level to form recesses having an inversed conical shape on the liquid level. Accoding to the present invention, the gas-liquid interface area can be increased by the recesses described above and the ejected gas is forced to form the flow from the bottoms of the recesses to the liquid level along the inner liquid surface of the recesses having an inversed conical shape, thereby improving the renewal ratio of the gas-liquid interface. Accordingly, migration of the gas materials can be promoted between the gaseous phase at the upper part of the incubation tank and the liquid phase of the culture solution while preventing bubbling of the culture solution.

Abstract: An electrical recording device for writing printing forms for printing machines is described which essentially consists of several writing units constructed as electrodes which can be individually connected to a voltage source in accordance with an image to be transmitted. In the case of a purely electrical device, the writing units consist of a stylus (20) which can be connected to a voltage source (23) via a photoconductor (21). An optical waveguide (25), in which a magneto-optical light switching module (31), which can be driven by means of current pulses (22) is interposed is used for driving the stylus (20). In one switch position, the light switching module (31) passes a light beam from a light source (28) from one optical waveguide section (27) into a second optical waveguide section (26), by which means the light rays pass through the photoconductor (21) and render it locally electrically conductive. In this manner, a potential by means of which, in conjunction with a counter-electrode (10), an electrical field (F) influencing the printing form (11) is generated is present at the stylus (20).

Abstract: There is disclosed a process of treating meal containing vegetable proteins. This process includes the step of extracting the meal at an extraction and washing zone 10 with a suitable aqueous solvent, e.g. aqueous sodium hydroxide, in which the vegetable proteins are soluble to obtain an extraction solution. The wet residue is suitably separated, e.g. by filter 12, from the extraction solution, and dried in dryer 13 to provide a meal residue C. The solubility of the dissolved protein in the extraction solution is then adjusted in zone 14 to precipitate at least some of the protein and therefore obtain a precipitated protein fraction and an unprecipitated protein fraction in solution. The precipitated protein fraction is then separated from the protein fraction in solution, and the unprecipitated protein fraction is separated from the undesirable components in the solution by membrane processing in a zone 18. Each of the protein fractions is then suitably dried in dryers 17 and 19 to recover the proteins. This process provides a commercially viable process for producing pure, good-grade protein from rapeseed.

Abstract: The invention is concerned with treatment of gelatins, so as to remove or reduce off-flavours. It has been determined that the off flavour may be reduced by membrane filtration to remove a low-molecular weight fraction. The invention provides gelatine substantially without a low molecular weight fraction and a process for the purification of gelatine which comprises removal of a low-molecular weight fraction by membrane filtration. While it is difficult to be precise about the substances responsible for the off-flavour, it is believed that 4- and 5-methyl indane are removed by the filtration. Accordingly, a further aspect of the present invention provides gelatine substantially free of 4- or 5-methyl indane, and a gelatine preparable by membrane filtration under such conditions as to substantially remove 4- and 5-methyl indane. While it is not confirmed that the methyl indanes are the per se cause of the off flavour it is proposed that the off flavour promoting species are removed under conditions which also remove the methyl indanes.

Abstract: An identifier generator produces unique identifiers for objects in a distributed computer system by concatenating (i) the identifier of the node associated with the object - a unique space component; (ii) the current time read from an associated clock, adjusted such that no two identifiers created by the same generator have the same current time, regardless of the resolution of the associated clock - a unique time component; and (iii) a random name-sequence; and (iv) a (software/hardware) version number. The generator stores the time and the random name-sequence components. When the next identifier is generated, the generator compares the then current time with the stored time component. If the times are equal, the current time is adjusted and the adjusted time is used as the new identifier time component. If the current time is less than the stored time, the generator changes the stored random name-sequence component and uses it and the current time as identifier components. If the random name sequence component used in the previous identifier is lost, the generator generates a new random name sequence and uses the new sequence and the then current time as identifier components. If the time component used in the previous identifier is lost, the generator changes the random name-sequence is a predetermined manner and uses it and the then current time as identifier components.

The step and repeat mechanism includes, means for moving the wafer to be exposed with six degrees of freedom. Conventional drive motor means move the step and repeat mechanism, and wafer held thereby, in the X, Y and Z linear directions, as well as rotates, tip and tilt the wafer in the planar direction. In addition, the system includes, three fine Z motor assemblies for moving the wafer in fine increments in the Z direction, which motor assemblies are used to tip and tilt the plane of the wafer. Sensors are included for determining the plane of the mask and the plane of each of the various sections of wafer to be exposed, so that appropriate tip and tilt adjustments by the three fine Z motor assemblies can be made to cause the average plane of each section of the wafer to be exposed to be parallel to the plane of the mask. All of the moving mechanisms, with the exception of the Y direction moving mechanism, are affixed the same level of the step and repeat mechanism. Included in the mechanism is a substage plate which is adjusted by the three triangularly positioned fine Z motor assemblies.

Title: Method for recovering trimethylbenzenes from mixtures which contain them
IPC: C07B61/00
Filed: 1990-10-04
Granted: 1993-04-28
Abstract: A method is disclosed for recovering high-purity trimethylbenzenes from mixtures in which such compounds are contained together with ethyl-toluenes and possibly also butyl-benzenes, which method consists of treating such a mixture with benzene in the presence of a heterogeneous acidic catalyst selected from the group consisting of the so-said acidic earths and some types of porous crystalline catalysts in their protonic form, under conditions of transalkylation, and of subsequently separating the trimethylbenzenes by distillation. In fact, the transalkylation with benzene makes it possible ethyl-toluenes and in particular 2-ethyl-toluene to be preferentially or selectively converted into toluene and ethylbenzene, and any possibly present butyl-benzenes to be drastically reduced in amount, thus enabling an easy separation of trimethylbenzenes and in particular of pseudocumene and mesitylen to be accomplished by means of a simple distillation step.
