Title: Pipe or rod bending device -  has rotary symmetrical bending mandrel with clamping and bending bar to bend angles more than 180 deg.
Inventor: JUNG GERHARD DIPL ING
IPC: B21D7/022
Filed: 1990-09-15
Abstract: The appts. to bend piping or rod material has a bending mandrel (2) with a rotary symmetrical shape, and the tube holder as a clamping bar (3) slides radially to the bending mandrel (2). The clamping bar (3) and the bending bar (4) are held durably at th the side of the bending mandrel (2) with the larger dia. so that, when the piping has been bent, it can be removed axially at the side of the bending mandrel (2) with the smaller dia. between the bending bar (4) and the clamping bar (3). The bending mandrel (2) is conical, with a straight mantle line, and the clamping bar (3) has a straight clamping surface (17).  A guide sleeve (5) for the piping slides on the bending bar (4).  A burl (6) extends radially from the guide sleeve (5), towards the bending mandrel (2), as an axial laying point for the piping, with a max. radial length of twice the piping dia. The bending bar (4) has a radial sliding movement, and swings through a controlled drive by a preset angle around the longitudinal axis of the bending mandrel (2). ADVANTAGE - The appts. gives a simple bending action with a bending angle more than 180 deg., and also successive bends in the same tube.

Title: Plant row irrigation device - has watering boom moved parallel to rows and programmed to stop over each row
Inventor: KNAUER JOACHIM FRIEDRICH
IPC: A01G25/09
Filed: 1990-09-25
Abstract: The watering boom (59) with its row of watering nozzles, is supported between two movable trolleys which move along fixed tracks.

Title: Forming trenches in single crystal silicon@ wafers - includes forming etching mask contg. parallelogram shaped window on (110) wafer face, anisotropically etching, etc.
Inventor: GRUENING HORST DR
IPC: H01L21/308
Filed: 1990-11-22
Abstract: Trenches in a single crystalline Si wafer with a (110) surface lane are formed using a masking layer featuring openings in the shape of a parallelogram with angles which are not 90 deg., and etched with an anisotropic process. The trench formed has at least one vertical and at least one sloping (6.1,6.2..) wall. The mask window has been aligned pref. with the long sides, which must form vertical sides, parallel to an intersection of the (110) plane with one of the 4 planes (1-11), (-11-1), (-111) or (1-1-1). The edges of the parallelogram which must form sloping walls, pref. the short sides, must be parallel to intersections of the (110) plane and the (111) or (11-1) planes. The etchant used is pref. 6-9 mole/l. of KOH at pref. 90 deg.C at which the etch rate ratio of 110 to 311 is as small as possible. The process also requires overhanging mask edges which are obtained by isotropic etching before the anisotropic etching is carried out. The parallelogram pref. has long sides which correspond with vertical walls and short sides corresp. with the sloping walls. USE/ADVANTAGE - The etching process is simple and reproducible. It produces vertical walls without excessive facets at the bottom of the trench. The etched surfaces are free of contamination and relatively few crystal defects are generated. The under cutting and trench dimensions have small tolerances. The process is used in the mfr. of GTO thyristors and/or field controlled thyristors.

Title: Process to inhibit growth of organisms on submerged surfaces - comprises coating surfaces with film contg. free ionic gps. and applying potential to cause extreme pH values in water by surface
Inventor: SANDROCK STEFAN DR RER NAT
IPC: C09D5/16
Filed: 1991-03-18
Abstract: A process for inhibiting growth on submerged surfaces comprises (a) coating the surface which is to be protected with a film contg. free ionic gps.; (b) applying a voltage to this film, which depending on the polarity and strength, gives an extreme pH value in a microscopically thin water layer above the film; and (c) reversing the polarity at irregular intervals to give a constant change of pH in the immediate vicinity of the surface. USE/ADVANTAGE - The extreme pH values inhibit the growth of organisms, esp. algae and bacteria. By charging the polarity and thus the pH, specialist organisms which have adapted to very high or very low pH values are not given the chance to grow. The process can be used on all types of ship, in off-shore technology, in power stations (cooling water) and in structures built in the sea and lakes in harbours. The highly poisonous paints contg. heavy metals such as organo tin cpds. and copper are avoided
