摘要:
Processes for preparing alkali metal alkoxide granules and alkaline earth metal alkoxide granules of aliphatic, saturated or unsaturated, unbranched or branched alcohols, preferably having 1 to 12, in particular 1 to 6, carbon atoms. A preferred process for preparing the alkoxides utilizes fluidized-bed spray granulation.
摘要:
The invention relates to a device for purifying protein-containing solutions such as blood, blood plasma or cell culture media, where a biocompatible support material made of a plastic material, selected from the group of polyacrylates, polymethacrylates, polysulfone and polyether sulfone, is coated with albumin, which is bound by peptide binding. In addition, the invention relates to a method of producing the support material according to this invention and the use of the device.

An adjuster for pivotally adjusting two vehicle parts to each other, is provided, the adjuster including a spindle pivotally arranged on the one vehicle part about a first pivot axis, an adjusting gear unit which includes a gear unit housing and is in engagement with the spindle via a spindle nut, and a holder arranged at the other vehicle part, which pivotally supports the adjusting gear unit on the other vehicle part about a second pivot axis and for this purpose at least partly encloses the gear unit housing of the adjusting gear unit in circumferential direction about the second pivot axis. The holder may be formed by a plastic retaining clip to form a light-weight and inexpensive adjuster that has high strength in operation.

The invention relates to an adjusting means (2) for pivotally adjusting two vehicle parts to each other, with a spindle (21) pivotally arranged on the one vehicle part about a first pivot axis (210), an adjusting gear unit (22) which includes a gear unit housing (23) and is in engagement with the spindle via a spindle nut (221), and a holder (3) arranged at the other vehicle part, which pivotally supports the adjusting gear unit on the other vehicle part about a second pivot axis (220) and for this purpose at least partly encloses the gear unit housing of the adjusting gear unit in circumferential direction about the second pivot axis (220). It is provided that the holder is formed by a plastic retaining clip (3). In this way, an adjusting means is created, which can be formed light-weight and inexpensive, but yet with high strength in operation.
摘要:
A process for the production or coating of granules in a fluidized bed, which includes heating a fluidized-bed gas to produce the fluidized bed, and applying a liquid medium containing a granule-forming or coating-forming compound, or at least one reaction component therefore, by spraying particles located in the fluidized bed and at a same time vaporizing an organic solvent contained in the liquid medium, said particles having a smaller mean diameter than that of particles to be produced. The process also includes partial condensation of an organic solvent from at least a portion of a fluidized-bed waste gas leaving the fluidized bed, and re-heating the fluidized bed-gas leaving the condensation device and reintroducing the re-heated gas into the fluidized bed.
摘要:
An apparatus for ascertaining and/or monitoring at least one temperature. The apparatus includes, according to a first variable, at least one temperature sensor, at least one reference temperature sensor, and at least one heating/cooling unit, which is thermally coupled with the temperature sensor and with the reference temperature sensor. According to a second variant, the invention includes that at least one reference temperature sensor, and the temperature sensor and the reference temperature sensor are embodied and placed in such a manner that they measure essentially the same temperature. At least one head transmitter is provided, which connects the temperature sensor and the reference temperature sensor with the head transmitter in such a manner that the head transmitter receives the data measured by the temperature sensor and the reference temperature sensor. At least one memory unit is provided, in which the measured data of the temperature sensor and the reference temperature sensor are storable.
摘要:
New alkali metal cyanide granulates based on sodium cyanide or potassium cyanide and a method for their preparation are disclosed. Commercially available alkali metal cyanide granulates consist of irregular particles; disadvantages are in particular the tendencies to form dust and to cake. The disclosed alkali metal cyanide granulates demonstrate a reduced tendency to cake and virtually no abrasion. The granulates are characterized by essentially spherical particles with particle diameters in the range 0.1 to 20 mm, a bulk density of more than 600 g/dm.sup.3, an abrasion of less than 1%, and a caking index of at most 4. The granulates can be prepared by fluidized bed spray granulation involving spraying an aqueous solution containing alkali metal cyanide onto alkali metal cyanide nuclei in a fluidized bed and evaporating the water.
