Patent EP-0341510-A2 (EP)
Inventor: KRISPEL FRANZ DR
IPC: H05H7/04
Filed: 1989-04-27
Abstract: The apparatus has a housing which encases an accelerating structure (1) as well as a magnet system (12-19). The accelerating structure accelerates an injected charged particle beam (6) within a first evacuated space and directs the beam into the magnet system which transports it along a bent beam path within a second evacuated space (30). Both spaces are separate from each other and the magnet system is supported within the housing such that it can be angularly adjusted with respect to the accelerating stdructure. In a preferred embodiment, the second evacuated spaced is partially defined by magnet poles (12, 13) of the magnet system and filled with helium under a pressure of higher than 10⁻² torr.

Title: Method for simultaneously grinding and cooling solid substances
Inventor: SCHMIDTKE WOLFGANG
IPC: B02C18/14
Filed: 1989-10-07
Abstract: The invention relates to a method and an apparatus for the simultaneous grinding and cooling of solid substances by means of a cutting mixer. The cutting mixer is evacuated in at least one vacuum stage, and refrigerated liquefied gas is introduced into the cutting mixer in at least one cooling stage. In order to optimise the method, it is proposed to draw off the waste gas arising during the cooling stage. A waste gas valve 12 is to this end advantageously installed which is closed before the end of the vacuum stage and opens after the latter is complete in order to draw off the waste gas arising during the cooling. <IMAGE>

Abstract: In a relational database system, a method is used that increases the performance of the sort operation. An optimiser routine in the relational database manager analyses a user's complete query to determine whether the final sorted results can be used directly by the user as sorting occurs. If the sort results can be used, the sort results are sent to Relational Data Services in the relational database manager for output to the user. 
     Depending upon the determination made by the optimiser routine, one of two output modes for the final sorted sequence string of data are selected by the relational database manager. In disk output mode, the last pass of the final sorted sequence string is written to disk. In fast direct output mode, the records of data are sent to the user as the final sorted sequence string is being merged during the last pass. 
     Such an arrangement reduces the total sort time by eliminating the overhead of writing to disk during the fast direct output mode. Also, the response time, or availability for each record is reduced since each record is retrieved or sent to the Relational Data Services immediately after it has been sorted into the final sort order instead of completing the entire sort first, and then writing to disk.

Abstract: Disclosed are a structure of a film with a good non-tackiness and a good adhesiveness for a high temperature cooking apparatus and a method of forming the film. A ceramic layer (34) including poly-titano-carbosilane is formed on a substrate (32) forming a cooking surface (25) or an inner surface of a heating chamber (8) of the high temperature cooking apparatus. A non-tacky resin layer (38) including a fluororesin is formed on the ceramic layer (34). At an interface between the ceramic layer (34) and the non-tacky resin layer (38), a proportion of poly-titano-carbosilane to the fluororesin changes successively in a vertical direction. In this film structure, the ceramic layer (34) and the non-tacky resin layer (38) are strongly bonded together with a good adhesiveness. Since the ceramic layer (34) includes poly-titano-carbosilane as its principal component, it is highly resistive to heat. Further, the film has an enhanced resisting property to corrosiveness because of the presence of the non-tacky resin layer (38) formed on the ceramic layer (34).

Abstract: 1. Method for continuously and quantitatively determining organic and inorganic carbon compounds (C compounds) in water. 2.1 Hitherto inorganically bound carbon was converted by acidification into carbon dioxide (CO2) which was expelled from the water with a gas. In this process, any readily volatile organic C compounds may also be transferred to the gas phase and evade detection in the liquid phase; they therefore have to be determined separately in the gas phase. The novel method makes it possible to determine the content of C compounds completely and independently of the volatility of the organic C compounds. 2.2 The water to be examined is acidified in an outgassing vessel; a carrier gas stream is passed through the water in the outgassing vessel. Water and carrier gas are fed from the outgassing vessel to a degrading reactor. The CO2 content of the carrier gas is determined downstream of the outgassing vessel and/or downstream of the degrading reactor. The proportions of inorganic and organic C compounds are determined separately from one another and/or as a total. 2.3 Determination of the content of C compounds in water down to the ppb range.
