Title: Stacker for up=ended sheets of paper - consists of conveyor to folding machine with braking rollers and deflector roller
Inventor: KUNTZSCH ROLF
IPC: B65H29/14
Filed: 1989-11-21

Title: Treating fresh water - by passage through anion exchanger loaded with carbonate ions
Inventor: ENSENAUER PETER
IPC: B01J41/05
Filed: 1989-11-25
Abstract: In treatment of water, fresh water contg. ions of neutral salts is led through an anion-exchanger loaded with carbonate ions. Pref. anions in the fresh water, e.g. HCO3(-), Cl(-), NO3(-) and/or SO4(2-) are exchanged against carbonate ions in the anion-exchanger, and (part of) the carbonate ions liberated in the exchange are pptd. with Ca(2+) ions present in the water, with formation of CaCO3. A basic anion-exchanger is pref. used and the treated water is brought to pH of 7.5-9. The exchanger is treated in a cycle with a liq. regenerating agent contg. an excess of free carbonate ions, esp. an aq. soln. of alkali carbonate, e.g. Na2CO3 or K2CO3, partic. a 2-10% soln. of Na2CO3. ADVANTAGE - The cationic and anionic properties of the water are changed, without addn. of Na or chloride to the water. @(8pp Dwg.not reproducible)

Title: Turning tool holder with chip breaking mechanism - has impulsive motion of tool superimposed on feed motion to produce breakable chip
Inventor: PFEIL ANTON DIPL ING
IPC: B23B25/02
Filed: 1989-12-05
Abstract: When workpieces of tough, ductile metals are turned a continuous chip is produced  which is difficult to clear from the working area and may constitutes a hazard. In the invention an oscillatory or impulsive motion is periodically superimposed on the feed motion of the tool (11) in the Z direction. This causes notches or weak points to occur along the chip, which will then easily break up. The toolholder (20) has an axis (22) normal to the x y plane about which the tool (11) can be momentarily pivoted to swing the tooltip (13) in the direction (37), thus producing a notch in the chip.  A mechanical, electrical or hydraulic mechanism (23) can be used to produce the actuating and return forces (26,27) on the tool. USE/ADVANTAGE - Improved clearance of chips. Safe operation.

Title: Active semiconductor structure esp. FET prodn.
Inventor: WIECK ANDREAS DIPL PHYS DR
IPC: H01L29/32
Filed: 1990-04-27
Abstract: In the prodn. of active semiconductor structures from initial structure having, parallel to the surface, a two-dimensional charge carrier layer provided with contacts, the novelty comprises the use of a focussed ion beam to cause linear destruction of the initial structure forming insulating material which divides the initial structure into regions or to build up lateral potential barriers in the 2-D charge carrier layer for dividing it into regions.  This results in the formulation, between at least one closed region and an opposite line, of a channel with a width of the same order of size as the thickness of the 2-D charge carrier layer (i.e. the electron wavelength), so that the closed  region as well as the regions formedd on both sides of the line are contacted. Also claimed are (i) an FET produced by the process and (ii) prodn.  of a (highly) integrated circuit by means of the process.
Patent DE-4019686-A1 (DE)
Inventor: HOLLER HELMUT DIPL ING
IPC: H01H31/00
Filed: 1990-06-18
Abstract: In an earthing switch (4) for an encapsulated high-voltage switchboard plant, the moving switching component (6) is moved by a rotating drive spindle (11) passing through the casing (5) of the earthing switch (4). In order to achieve the simplest possible construction of the contacts transferring the earth potential to the movable switching member (6), the drive spindle (11) made of electrically conductive material is inserted into the casing (5) via insulation and connected outside the casing (5) by means for transmitting the earth potential, e.g. a current lead (14). The drive spindle (11) thus transmits both the power and the potential. The movable switching member is a switching blade (7, 8) which is partially elastically deformable. Such an earthing switch for an encapsulated, pressurised-gas-insulated switchboard plant may also be used as an insulated switch for measurement purposes.
