Title: Air-cored reactor with cylindrical winding - supported on cage structure carried on end-plates
Inventor: SCHMITZ ERNST
IPC: H01F30/08
Filed: 1978-12-09
Abstract: The support for the reactor winding is provided by an assembly of axial bars (2) which are keyed into a disc (3) at each end. For windings with a large axial length intermediate supporting plates (7) may be added part way along the bars to improve dimensional stability. Spacers (5) forming distance pieces to locate and give separation between adjacent winding discs are keyed (6) to the radially outer face of each support bar (2). The arrangement eliminates the need for a solid cylindrical tube as a winding support. With the elimination of the tube, oil can circulate much more freely round the winding giving more intensive cooling. The end (3) and intermediate discs (7) may have locations (4) for the spindle of coil winding machine.

Title: Automatic controlled water valve - has damping piston fixed to operating plunger to delay return to closed condition
Inventor: RUPPEL HORST-FRIEDRICH
IPC: F16K21/10
Filed: 1979-03-07
Abstract: The valve head of an automatic water valve is lifted off its seat to connect inlet and outlet ports, by an operating plunger, fixed to an operating button. Return to the closed condition is ensured by a spring beneath the button. A piston fixed to the plunger slides in a damping chamber as the latter is operated.

Title: Nitrogen, phosphorus and potassium determn. in plants and fertilisers - by measurement of gamma radiation spectra induced by neutron bombardment
Inventor: SRAPENJANC RIGO ARTEMIEVITSCH
IPC: G01N23/222
Filed: 1979-04-19
Abstract: New process is claimed for simultaneous determin of the content of N, P and K nitrogen, phosphous, potassium in plants and fertilisers by neutron irradiation specimens to be analysed and of control specimens, subsequent spectral registration of induced gamma radiation, and determn of the N, P and K concn. from the spectra obtd. After the first spectral registration, the specimen to be analysed and the control specimen are stored for a time period determined by the half-life of an intrifering isotope. Spectral registration of both specimens is then repeated. For both the specimen to be analysed and the control specimen, the two spectra are superimposed, and the contents of the elements under analysis are determined by comparison of the superimposed spectra of the specimen to be analysed and the control specimen. Improved accuracy is obtd attributed to consideration of both energy distribution of the gamma radiation and its change with time.

Title: Pick=up arm for record player - has opto-electronic device producing signal proportional to deflection of support arm and thus to pressure of stylus on disc
Inventor: REDLICH HORST
IPC: G11B3/12
Filed: 1979-04-21
Abstract: The pick-up arm has its stylus at the end of a sprung support arm which is fixed to a casing moving radially over the disc. A measurement unit (15-18) measures the deflection of the support arm (5) relative to the casing (7) caused by the force with which the stylus rests on the surface of the disc (1). The measurement unit produces a signal (Us) that adjusts the height of the casing relative to the disc. The measurement unit is an optoelectronic device. A shutter (15) is fixed to the support arm and progressively shuts off light reaching two photodiodes (17, 18) from a light source (16). The photodiodes are connected in series and shunted by a capacitor and potentiometer. The potentiometer's slider and the junction between the diodes are connected to the inputs of a differential amplifier.

Title: Flexible roller support - controls pressure outflow according to gap between head section and supported surface
Inventor: GUETTINGER HEINZ DIPL ING
IPC: F16C32/06
Filed: 1980-03-18
Abstract: In the support system for a flexible roller mantle, for processing web material, there is at least one pressure zone to support the head section towards the surface to be supported. The pressure in the zone is controlled by measuring the gap between the head section and the surface to be supported. Specifically with a constant pressure feed into the pressure zone, the escape of the medium is controlled. A sliding sensor measures the gap between the head section and the supported surface which delivers a signal to determine the rate of pressure medium outflow from the pressure zone, by a valve acting on the outflow. There can also be a ring throttle between the supported surface and the outflow, so that the outflow resistance can be used to generate a signal to control the escape of pressure medium from the pressure zone, using the effect of a hydrostatic pressure pocket at the circular gap, which can be moved by a hydraulic motor against the head section. System ensures parallelism between the head section and the surface to be supported under all operating conditions, and allows support across a wide pressing zone.
Patent DE-3011755-A1 (DE)
Inventor: HUBER HANS ULRICH
IPC: H05K1/00
Filed: 1980-03-26
Abstract: The printed circuits (2) provided with conductor tracks and separated from the remaining substrate material are inserted into special cutouts in a template-like assembly frame (7) and elastically clamped in a predetermined position in these cutouts. This is followed by fitting circuit components to the printed circuits (2) held in the assembly frame (7) and aligned in the favourable position for fitting the components. The assembly frame is advantageously strip-shaped and consists of steel. The method leads to savings in substrate material and results in a more accurate positioning and proper holding of the printed circuits during the fitting process, the bonding or other further processing of the printed circuits (2) to become the actual printed circuits or electronic modules for hearing aids, pocket calculators, electronic clocks and so forth. <IMAGE>

Title: Probe for testing semiconductor chips - is made from cold workable material formed into taper with perpendicular contact tip at narrowest end
Inventor: TRETENHAHN FRIEDRICH
IPC: H01R11/18
Filed: 1980-04-12
Abstract: The application is to test apparatus for use during semiconductor chip manufacture. The contact probe has small dimensions to permit a high density of probes in the test apparatus, and has high resistance to bending or deformation. The probe is made from a cold workable material, typically beryllium bronze. It is tapered on two opposite sides (2, 3) towards a point. At the narrowest end of the tapered section is formed a tip (11), approximately at right angles to the axis of the probe. The tapered section is preferably press-formed, and the tip section (9, 10, 11) cut or punched out of the tapered blank. Electrolytic machining may then be employed to obtain a smooth, rounded contact tip.
