Title: NC machine tool fast reacting servo drive - uses phase signals corresp. to rotary angle of sync. machine to control current
Inventor: MALL HANS-GEORG DIPL ING
IPC: H02P25/03
Filed: 1979-04-20
Abstract: The fast reacting servo drive for e.g. a numerically controlled machine tool, uses a converter self controlled synchronous machine (1) and an angle indicator (4) which provides signals corresponding to the angle of rotation of the rotor (2). Phase signals (11) corresponding to the angle of rotation are fed to multipliers (10) for each phase, and their outputs (12) fed to equalisers (13) and current controllers (18) to the stator windings (16). A tachogenerator (5) connected to the angle indicator is followed by an equaliser (6) and a rotary speed controlled (9) interconnected with the multipliers.

Patent DE-2920708-A1 (DE)
Title: Blade mfr. process for woodworking machinery - uses rolled strip of slightly decarburised steel requiring only single grinding stage
Inventor: STEHLE WOLFGANG DIPL ING
IPC: B23P15/28
Filed: 1979-05-22
Abstract: The blades used on woodworking machinery can be made from a surface hardening steel, instead of the usual through hardening steel, by beginning with a rolled strip of suitable cross-section. The strip is cut into lengths of the required size and these blanks are then hardened. The blades are then subjected to only a single grinding operation to produce a cutting edge. The grinding of large areas of blade is thus omitted with a reduced manufacturing cost and less material wastage. A slightly decarburised steel is most suitable for this method of manufacture.

Patent DE-2932459-A1 (DE)
Title: Solid particles dissolution in liq. media - by metering, grinding and recycling side stream of mixt.
Inventor: VOGEL GEERT
IPC: B01F13/10
Filed: 1979-08-10
Abstract: A method of dissolving solid particles in liquid media, for example viscosity index correctives in granular or powder form in mineral oil to improve the viscosity index, uses a mixing tank for the particles and the oil from which the mixture is extracted and recycled back to the mixing tank. Before the particles are added, they are metered, ground in a colloidal mill, and passed partly dissolved to the mixing tank. A side stream of the mixture is branched off at the mill and is recycled to the metering funnel. This prevents any deposits of solid particles on parts of the circuit. A faster dissolution rate at a lower temperature reduces the power costs and the time required.
Patent DE-2934515-A1 (DE)
Title: Liq. fuel fired boiler - has standby tank in return pipe to tank with separate standby pipe to pump
Inventor: BOLLMEYER DIETER
IPC: F23K5/04
Filed: 1979-08-27
Abstract: The oil, or other liquid fuel, fired boiler has a fuel tank connected by supply and return pipes, both of which can be shut-off to the burner feed pump. A stand-by tank (5) is connected in the return pipe (10) from the pump (3) to the main fuel tank (4), and from this a separate stand-by pipe (12) with its own stop valve (11) leads back to the pump. The stop valves in the feed and return pipes can be combined into a control unit shutting off one or the other, or both as desired. The design allows the stand-by tank to be mounted inside the building, but the main one outside, so that fuel is always available for the pump even during severe frost.

Title: Electromechanical bell with adjustable loudness - has spring ensuring vibration at lowest setting
Inventor: ANTON HORST
IPC: G10K1/064
Filed: 1980-11-11
Abstract: The bell has a permanent magnet and a drive coil moving a flat armature parallel to the coil's axis. The armature has a hammer attached to it that strikes two hemispherical metal shells to produce sound.

Patent DE-3110855-A1 (DE)
Title: Working cylinder with three positions
Inventor: KLATT ALFRED ING GRAD
IPC: F15B11/12
Filed: 1981-03-20
Abstract: The invention relates to a working cylinder with three positions which is designed as a double-acting working cylinder. Two annular sealing elements are displaceably arranged on the working piston. The displacement movement of the sealing elements is effected by the pressure medium in the two pressure medium chambers bounded by the working piston. Three stops provided on the working piston, one stop being arranged between the two sealing elements, as well as a fourth stop provided on the inner wall of the cylinder housing likewise between the two sealing elements limit the displacement movement of the sealing elements. Depending on the direction of movement of the working piston, each of the two sealing elements has the task of either increasing the rod-side effective area of the working piston or the effective area of the working piston opposite the rod-side effective area. When the pressures in the pressure-medium chambers are at the same level, the working piston is thus moved from the respective end position into the centre position.
