Patent DE-4208169-A1 (DE)
Title: Method of removing micro-fine foreign bodies from surface - involves wetting surface with water, freezing and subsequently thawing
Inventor: ARAI ICHIRO
IPC: B08B5/02
Filed: 1992-03-13
Abstract: Micro-fine foreign bodies are removed from the surfaces of articles by a method which first involves wetting the surface with water. The water is then frozen so that the foreign bodies are trapped in the coating of ice. The surface is then flushed with air at normal temperature. The air melts the ice and the foreign bodies are removed with the water as it flows off the surfaces of the articles. The method is especially intended for cleaning containers used for pharmaceutical products. USE/ADVANTAGE - Cleaning of pharmaceutical containers. The method removes micro-fine foreign bodies.

Patent DE-4217258-A1 (DE)
Inventor: BAREIS HELMUT
IPC: B62D5/083
Filed: 1992-05-25
Abstract: The invention concerns a power-assisted hydraulic steering system with a rotary-spool valve (5, 6) and in which the relationship between the hand steering force and the hydraulic assistance can be characterized by the valve characteristic curve. Generally, a tight tolerance interval is required for this characteristic curve. The aim of the invention is to provide a device for the adjustment of the valve characteristic curve. In addition to the slot zones (Z, Z1) for normal control of the servo motor (27), the invention calls for additional zones (S, S1) for redistributing the hydraulic-fluid flow. Fitted in the return channel of the additional slot zones (S, S1) is an adjustable shutter (32). By modifying the hydraulic-fluid flow emerging through these slot zones (S, S1), the valve characteristic curve can be corrected.

(I) can also be used to prevent reverse twist in nematic LC phases. In an example, a mixt. of 6 mmoles 1-r-cyano-1-heptyl-cis-4- (4'-hydroxybiphenyl-4-yl)- cyclohexane, 6 mmoles pyridine and 10ml toluene was mixed with a suspension of 6 mmoles camphanic acid chloride in 6ml toluene, heated for 1 hr. at 100 deg.C, cooled and poured into 50ml water; this mixt. was worked up by extn. with methyl tert.-butyl ether, evapn. and recrystallisation from EtOH/EtOAc (1:2) to give cpd. (I), where R1 is Me; A is CMe2; p is 1; Zo is COO; n is 0; MG is 4-(4'-cyano-4'-heptyl- cyclohexyl)-biphenylyl. The prod. had phase transitions, K 153 Ch 151 I. A 9-component LC base mixt. with K below 0 Sc 87 S(A) 80 N 96 I was doped with 10% (I) to give a ferroelectric medium with K below -10 Sc 73 S(A) 79 Ch 99 I (where K is cryst. solid, Ch is cholesteric, S is smectic, N is nematic, I is isotropic phase).

Title: A data processing system which permits user dialogue in a plurality of natural languages
Inventor: MERZ LAUREN
IPC: G06F9/451
Filed: 1993-07-27
Abstract: A data processing system which permits user dialogue in a plurality of natural languages contains a processor for executing application programs, a memory for storing message (information, communication) files, which are associated with the application program, in at least one natural language and a link table for storing links between the application program and associated message files, a link storing an application program of one natural language and a pointer which indicates its message files. The operating system of the processor constructs links when a message file is loaded in the memory. The data processing system nests language information for nested application programs. A recovery mechanism is used to provide a standard language when a language desired by the user is not available and/or when nested languages are not available. The system can send and receive messages in a plurality of natural languages with the simultaneous use of different application programs in a manner which is clear to the user and the application programmer with support from the involvement of the operating system in the construction of links with the use of standard languages and the nesting of language information. <IMAGE>
