Title: Filling hoppers with different powders - by using automatic control system with vacuum pipelines, various storage silos and valves, to fill hoppers with filling level regulators
Inventor: ENDE HEINZ DIPL ING
IPC: B65G53/66
Filed: 1991-03-14
Abstract: In a plant for handling powders, and, in particular, a foaming plant for expandable polystyrene, a number of hoppers are filled automatically and efficiently, and  by vacuum from storage silos to hoppers fitted with level regulators. All the filling requirements of the regulators are arranged in cycles by a chain of successive operations; the procedure always starts by filling a hopper by the shortest feed path of the system. The other hoppers are filled by successively longer routes, and, at the end of the sequence, but before the last feeder is stopped, feed to the storage silos is halted. The  complete feed path is then drawn free and the sequence is ended by cutting out the last vacuum feeder. During the whole filling process the volume of feed air is controlled and if the vol is too low the supply of material from the storage silos is stopped so that the feed line is drawn freely before the filling process recommences or is interrupted by programme. ADVANTAGE - The system functions automatically. It can operate with powders of different types if necessary.
Patent DE-4115306-A1 (DE)
Inventor: GAHLEITNER ALFRED PROF
IPC: B60K1/00
Filed: 1991-05-10
Abstract: The invention proposes a four wheel drive hybrid vehicle with an internal combustion engine (16) and an electric drive system (24) in which the internal combustion engine is fitted forward and all four wheels are driven, the rear ones via a propeller shaft (20). The electric motor (24) is associated with the propeller shaft and takes the form of a permanent-magnet synchronous motor, the rotor of which is a part of the propeller shaft. This provides permanent four wheel drive during propulsion by either the internal combustion engine or the electric drive system.

Title: Tool-holder for engineering machining - has tapered tool clamping sleeve which is split down part of its length
Inventor: WOZAR J-ANDREAS DIPL ING
IPC: B23B31/20
Filed: 1991-05-16
Abstract: The tool holder (18) has an inner conically tapered sleeve (10) in which a cylindrical tool (11) is clamped. The sleeve is split for part of its length, and at the root of these splits the cross sectional area of the fingers (27) is reduced so as to enable them to be elastically deformed and compress in upon the tool shaft (11). The reduction in cross sectional area can be by either an local increase in the dia. of the hole (29) or by a external grove (33). The protruding length of the tool (11) can be adjusted by means of an adjustable end stop (40). USE/ADVANTAGE - Has relatively few simple components and enable high clamping forces to be exerted on the cutting tool whilst retaining a high degree of concentricity when cutting.

Title: Changing colour of small portions of hair - by winding hair strands on rollers, applying viscous colouring agent, rinsing and drying
Inventor: RAU ROBERT DR
IPC: A45D19/00
Filed: 1991-07-08
Abstract: Hair is divided into strands, the strands are coiled on rollers so that the single windings of hair lie next to one another. A colour-changing agent is contacted with the hair strands in one or more strips parallel to the axis of the roller, where the consistency of the agent is so high that the agent cannot immediately penetrate to parts of the strands not in contact with the agent. The agent is rinsed from the hair after sufficient time for it to be effective, pref. after removing the rollers, and the hair is dried. The agent pref. has a viscosity of 100-1000 mPa.s at 30 deg.C and is esp. a bleach. Before application of the agent, a protective casing, with at least one lengthways slit, is pulled over the roller. The roller (6) has a ridge (14), and is covered by a protective casing (10) with lengthwise slits (11, 12) opt. open at one end and closed at the other, and with a finger (15) which contacts the ridge (14). The roller and casing are not cylindrical pref. elliptical. ADVANTAGE - The method is simple and gives reproducible effects, underlying hair layers can be treated as well as the upper layers, and unwanted treatment of some of the hair is avoided.

Title: Removal of oil from metal-working waste - involving use of a high-pressure water jet
Inventor: FROEHLICH GEORG DR
IPC: C23G3/00
Filed: 1992-02-19
Abstract: Sepn. of oil from metal-working waste (swarf, slurries etc.) involves preliminary mixing of the waste with an emulsifier without addition of water. This is followed by a washing process with the use of a water-based rinsing liquid. Oil emulsifies in the rinsing liq. and is sepd. from the washed solids.
