Patent DE-4030871-A1 (DE)
Title: Vehicular hydraulic braking system with antilock protection device -  includes two pressure reservoirs and recirculation of brake fluid, with safety valve to protect smaller reservoir
Inventor: FRIEDOW MICHAEL
IPC: B60T8/48
Filed: 1990-09-29
Abstract: A pump protection valve (15) closed by a spring (23) preventing reverse flow is introduced between the return pump (10) and the master cylinder (4). Locking of a brake (6 or 7) drains fluid into a first pressure reservoir (9) from which it is pumped (20) into a second pressure reservoir (11), providing for renewed braking when risk of a skid has been averted. The valve (15) opens when the pressure in the second reservoir (11) exceeds its limit, reacting on the brake pedal (3). ADVANTAGE - The second pressure reservoir can have smaller capacity, while excess fluid can be absorbed in the master cylinder.

Patent DE-4131505-A1 (DE)
Inventor: BIERMANN MANFRED
IPC: C07H13/06
Filed: 1991-09-21
Abstract: The invention concerns the reaction mixture obtained in the solvent-free production of saccharose esters of fatty acids by the esterification of saccharose with alkyl esters, preferably methyl esters, of fatty acids in the presence of a basic transesterification catalyst. When processing this reaction mixture, unreacted saccharose is filtered off at a temperature between the melting points of the saccharose used and the saccharose ester produced. Unreacted fatty-acid alkyl ester is subsequently distilled off from the reaction mixture. The cost of the process is reduced considerably for an end product which is of the same or even higher quality.

Title: Clay processing - comprises mixing and homogenising followed by separate granulation stage with continuous movement through both
IPC: C04B33/02
Filed: 1991-10-31
Abstract: To homogenise, mix and granulate malleable clays, with a moisture content of more than 15 wt.% of the dry material, the homogenising and mixing actions on one side and the granulation on the other side are effected separtely and successively in at least two different assemblies with separate settings for the process conditions. The start material for homogenising and mixing is fed continuously to the first assembly, and transferred continuously to the granulating appts. After granulation, the material is taken off continuously. Additives are pref. mixed in with the clay at the first appts., esp. with a content of C and/or ferrous oxide, to increase or decrease the malleable character of the clay and to affect the clay softening and melting properties. At the second stage, additives are introduced to aid granulation, e.g. lignin sulphate. USE/ADVANTAGE - For mfg. aerated clay. The process eliminates a drying stage, and gives an optimum mixing action to delivery constant granule sizes for the prodn. of aerated clay.
