Patent DE-2555082-A1 (DE)
Title: Fully automatic positioning device - positions objects along linear scale or to angular settings
IPC: G05D3/18
Filed: 1975-12-06
Abstract: An automatic electronic positioning device for settling a moving part on an exact position along a linear scale, or at an exact angular position on a circle, expresses the required position as a voltage level serving as a reference for the servo-positioning control. A transducer which can convert a linear or angular measure into an electrical quantity may also be an angular transductor for linear positioning with appropriate matching. An electronic system senses the error between the required position and the actual setting read from the transducer and generates an error signal which causes the part to be shifted until the error is removed. The accuracy depends on a resolver acting as the transducer, having two pairs of windings, a stator winding and a rotor winding, each pair consisting of two windings at right angles, in goniometer fashion. The resolver primary is fed with a.c. and the induced secondary voltage is demodulated to derive a signal representing the angular setting. The operating voltages are generated in a digital electronic circuits automatically.

Title: Flexural mode electromechanical filter - has attenuation pole characteristics obtained by extra coupling between two resonators
Inventor: ALBSMEIER HANS ING GRAD
IPC: H03H9/50
Filed: 1976-02-26
Abstract: The flexural-mode electromechanical filter has parallel rod-shaped resonators connected by wires and lying in the same plane. Electrostrictive transducers are coupled to the input and output of the chain of resonators. Two of the resonators (4, 5) are bridged by a first wire (11) that connects the two resonators adjacent to them. A second coupling (10) connects the two resonators (4, 5) together at points that are vibrating out of phase with one another. The second coupling elements are parallel to one another and symmetric about the long axis of the filter. The second coupling produces an attenuation pole in the filter characteristics.

Title: Production of longitudinally seam welded tube - has successive sets of rollers to bend steel strip to cylindrical form
Inventor: HIRZ KURT
IPC: B21C37/08
Filed: 1976-03-01
Abstract: The steel strip (5) is passed between two rollers with parallel axes (3, 4). The centre section of each roller is cylindrical but the profiles of the ends of the rollers form matching curves and impart curved edges (6, 7) to the strip (5). The strip (5) then passes through a second set of rollers consisting of two horizontal rollers (13, 14) one with a convex and the other with a concave profile. Two additional rollers (11, 12) with axes (9, 10) vertical have profiles to match the already curved edges. These rollers form the strip to a semi-ellipse. Three further sets of rollers increase the curvature of the strip until a cylindrical form is reached with the strip edges abutting one another and ready for welding.

Inventor: GIESINGER HANS
IPC: H03B5/26
Filed: 1976-03-29
Abstract: The high voltage generator, suitable for use with electrostatic powder charge systems, uses an RC oscillator of the Wien-Robinson type coupled to the low voltage winding of a transformer. The oscillator is coupled in such a way that the frequency is dependent upon the low voltage transformer winding to provide matching with the output load impedance. The oscillator (R2C2) is coupled to a power transistor stage (T) consisting of a transistor (T2) and a drive transistor (T3). The drive transistor base is coupled over a parallel RC circuit (R4C3) with a series resistor (R3) to the positive pole of the d.c. supply. The oscillator feedback loop consists of an RC circuit (R1C1) between the power stage collector and the low voltage winding.

Pref. the products where R3-6 are aromatic gps., R5 and R6 may also be H, aliphatic, cycloaliphatic or araliphatic, and R4 may be H, are subsequently treated with an acid at pH 1-7. (I) are stabilisers; intermediates for dyes (e.g. indigo) fungicides, bactericides, textile auxiliaries and antigelling agents; and by saponification give glycine salts useful as selective adsorbents for CO2, SO2 and H2S, and by hydrogenation give assymetric diamines useful for making pharmaceuticals and plant protection agents. Cf. the process of DT 1543342. This method is simpler and more economic giving better yields of purer products. Water pollution and formation of resinous by-products are minimised, and subsequent acid treatment obviates expensive purification steps and avoids losses of solvent.

Title: Mono-aluminium phosphate soln. reacted with ethanolamine - to obtain binder with long storage life for refractories contg. alumina
Inventor: DORN KARLHEINZ DR RER NAT
IPC: C04B35/63
Filed: 1976-08-27
Abstract: Binder is for refractory masses contg. alumina, where the binder is a reaction prod. of mono- Al phosphate, Al(H2PO4)3(MAP) and ethanolamine, with pH 2.3-8, esp. pH 5-7. The ethanolamine may be mono-, di, or tri-ethanolamine, added to a MAP soln. at =60 degrees C to obtain pH 2.3-8, esp. 5-7. The binder is pref. added to the refractory in presence of adequate moisture, and the mixt. then enclosed in a packing which is impermeable to moisture, then sent to its place of use for working. Used for binding chamotte, corundum, bauxite etc. When conventional MAP soln. is mixed with a refractory, the resultant mixt. only has a limited storage- or shelf-life, as premature bardening occurs; the mixt. can then not be pressed and/or results in prods. with inferior density, increased porosity and high water adsorption. The invention uses ethanolamine to neutralise the MAP and form a complex which is inly destroyed by heat so a mixt. of refractory and the binder has a long storage life.
