Title: Starting control for gas turbine engine - has electronic control for progressive start=up with intermediate speed and final operating speed
Inventor: VERTENS PETER
IPC: F02C7/26
Filed: 1992-07-03
Abstract: The fuel injector (2) is fed by parallel pumps (4,4') with variable output.

Patent DE-4243221-A1 (DE)
Title: Electric toothbrush
Inventor: WICH ROBERT DIPL ING
IPC: A61C17/34
Filed: 1992-12-19
Abstract: The electric toothbrush has a motor in the handle driving a shaft (3) through a gearbox. The driving mode is oscillatory.

Title: Process for the preparation of ketones
Inventor: BRAUN MAX DR
IPC: C07C45/48
Filed: 1993-04-27
Abstract: There is described a novel process for the preparation of ketones, for example of CF3C(O)CH3, CF3C(O)CH2C(O)CF3 and CF3C(O)CF2H. In this process, ss-ketoesters are transesterified with a carboxylic acid, for example trifluoroacetic acid, in the presence of an "onium" salt of a carboxylic acid, alkyl- or arylsulphonic acid or a mineral acid and decarboxylated. The process is carried out under anhydrous conditions. No acetals or hydrates are therefore formed, so a dehydration stage is unnecessary. A further advantage of the process is the simple way it is carried out.
Patent DE-4315772-A1 (DE)
Inventor: SUERMANN BERTHOLD DIPL ING
IPC: H01F38/28
Filed: 1993-05-07

Title: Device for treating cooling fluids
Inventor: PFLIEGER KLAUS
IPC: F15D1/00
Filed: 1993-08-26
Abstract: To improve the service life of cooling fluids for machine tools, such as lathes or grinders, there is inserted into the cooling circuit a device (18) which consists essentially of a tubular housing (21, 22, 23) with an inlet stub (25) at one end and an outlet stub (26) at the other end. Arranged in the housing are a plurality of discs (28, 29, 30, 37) which lie one against the other and are designed as perforated discs or screen nettings. The holes or screen meshes divide the incoming cooling fluid into a multiplicity of partial streams and form, owing to their special mutual arrangement, in each case a plurality of flow constrictions lying in the partial streams, preferably with lateral offset of the partial streams between the flow constrictions. The molecular chains of the additives present in the cooling fluid are thereby flexed and stretched to a certain extent, so that they pass through the working zone with greater suppleness and less heavy damage. <IMAGE>
