Patent DE-69011290-D1 (DE)
Inventor: CURTIS THOMAS ARNOLD
IPC: C07B61/00
Filed: 1990-12-03
Granted: 1994-09-08
Abstract: A method is provided for separating hydrogen fluoride (HF) from a mixture comprising HF complexed with an aromatic ketone in which the keto carbon atom is directly bonded to an aromatic ring carbon atom, e.g., 4-isobutylacetophenone, by adding a carboxylic acid anhydride, e.g., acetic anhydride, to the mixture while maintaining the mixture at conditions sufficient to sustain a reaction between the anhydride and the HF to form the corresponding acyl fluoride, e.g., acetyl fluoride, and carboxylic acid, e.g., acetic acid, and separating the acyl fluoride from the mixture. The method is conveniently carried out in a stripping column near the top of which the mixture comprising aromatic ketone and HF is fed and below which the anhydride is fed. Between these feed points, the uncomplexed HF is stripped from the mixture, while below the anhydride feed point or points, the anhydride reacts with the complexed HF to form the acyl fluoride which is stripped from the mixture, and the carboxylic acid. The separation method may be integrated with the production of the aromatic ketone by the Friedel-Crafts acylation of an aromatic compound, e.g., isobutylbenzene with an acyl fluoride, a carboxylic acid anhydride, a free carboxylic acid, or a mixture of the foregoing reactants, using an excess of HF as catalyst, to produce the mixture comprising aromatic ketone and HF to be separated, and to which the separated HF and in some cases the acyl fluoride may be recycled.

Abstract: An apparatus for storing and reading a magneto-optical disk has a slit shaped aperture (40) located in an air-bearing slider (30) which flies above the disk (10). Domains of the disk are selected for storing or reading by a light beam (13). The domains are reduced in size without losing inter-domain resolution by illuminating the disk with the portion of a focused laser beam incident on the disk through the slit (40), the slit width being less than the full beam width. The slider preferably terminates a wedge-shaped cavity (34) suspended above the medium a distance substantially less than the wavelength of the illuminating light; the thickness of the walls of the slit being substantially less than the wavelength of the illuminating light.

Abstract: The apparatus for layering powder (157) onto particles (191) has a vessel (1) in which a rotor (21) is mounted rotatable around a vertical axis (3). The rotor (21) comprises a disc (23) with a supporting surface (23a) for supporting particles (191). The apparatus also has feeding means (67) with a substantially horizontal introducing member (71) protruding slightly into the vessel (1) above the disc (23). The introducing member (71) limits a liquid outlet and an annular powder outlet encompassing the liquid outlet. During a layering operation, the introducing member (71) protrudes into a bed of particles (191) lying on the rotating disc (23) and moved by the latter. There can then be sprayed liquid (129) and powder (157) simultaneously by one and the same introducing member (71) onto the particles (191) passing in proximity of said outlets. This enables layering powder (157) onto particles (191) and to produce thereby pellets having sizes lying in a narrow range, wherein the pellets can be produced by using only a small amount of liquid and in short time.   <IMAGE>

Abstract: Methods for detecting granulocytes and for providing an at least semiquantitative indication of granulocyte level and kits for implementing those methods. A blood sample is drawn, and components that might interfere with the assay are removed and/or neutralized. Granulocytes present in the sample are then disrupted to release intracellular myeloperoxidase, and the sample is contacted with a peroxide and a chromogenic donor dye. The myeloperoxidase enzyme catalyzes hydrogen peroxide-involved reactions which result in the dye changing color if, and to the extent that, granulocytes are present in the blood sample.

Abstract: A method of introducing air into a room by passing supply air (A) into a distribution device (1) ending in the room (2) and by blowing the air from the distribution device through air supply openings (8, 9) into the room. In order to control the introduction of air even when the supply air is considerably warmer than the room air, the supply air is introduced into the distribution device selectively through two separate independent flow paths (4, 5) into the air supply openings, whereby the supply air is subjected to flow conditions required for heating at the air supply openings (8) of one flow path and correspondingly to flow conditions required for cooling at the air supply openings (9) of the other flow path. A distribution device carrying out the method comprises at least two separate alternative flow ducts (4, 5) for supply air, the flow ducts being provided with separate air supply openings (8, 9) which provide different flow conditions in the separate flow ducts.
