Patent DE-4038976-A1 (DE)
Title: Energy-changer between power supply and load - uses rectifier or variable-ratio transformer or AC current pulse converter
Inventor: MEYER KLAUS
IPC: H02M7/00
Filed: 1990-12-06
Abstract: The use of an energy-changer between an electrical source and a load can improve the overall efficiency. For example, the energy-changer could convert alternating current into pulses for supplying gas-filled lamps, utilising the afterglow effect of the lamps. For heating apparatus, the energy-changer could be a rectifier, thereby improving the power factor. For controlling the current to a set of street lamps, the energy-changer could entail a variable-ratio transformer, obviating the need for switches. USE/ADVANTAGE - Energy-converter between electrical source and load which can improve overall efficiency.

Title: Segment-wise approximation of envelope curve logarithm - feeding direct and delayed quadrature signals to amplitude comparator with individually variable weighting factors
Inventor: LANGE WOLF-DIETRICH DIPL ING
IPC: G06G7/24
Filed: 1991-03-13
Abstract: Segment-wise approximation of the logarithm of the envelope of bandpass signals in differential form involves separating an input signal into a direct component and one delayed by the transition time, regulating their phase difference in a quadrature unit and feeding the direct and delayed quadrature signals to an amplitude comparison unit with individually variable comparator weighting factors. A first approximation to a section of the logarithm is formed from the phase difference arising in the amplitude comparison and the quadrature error is corrected. A null point computation is performed to improve the approximation and a systematic approximation error is derived. ADVANTAGE - Increased accuracy of approximation of logarithmic characteristics is achieved over greater dynamic range.

Title: Purification of waste gas contg. prods. of incomplete combustion - by adsorption on zeolite
Inventor: HORCH KLAUS DR
IPC: B01J20/18
Filed: 1991-04-25
Abstract: In purification of waste gas, where, in addn. to removal of dust, HCl, HF, SO2 and opt. NOx, harmful substances, esp. prods. of incomplete combustion (PIC) are removed by adsorption on an adsorbent, the adsorbent is a zeolite with SiO2/Al2O3 molar ratio of 2-6. USE/ADVANTAGE - Appln. is cleaning of flue gases from waste combustion plant or power plant, and of waste gas from processing of sewage sludge. The content of highly toxic PIC (esp. dioxins and furans) in waste gas, measured as toxic units, is reduced by 99%, even with waste gas with a high water content. The content of metals, e.g. Hg, Cd, Pb, Zn, Cu, salts and other prods. is also reduced. Use of the zeolite causes (partial) destruction of the PIC by dechlorination, and the zeolite is not loaded with toxic PIC, or is less loaded than are other adsorbents. The adsorbent is not self-igniting, and slow combustion does not occur. The zeolite is easily available. Treatment is at 70-200 deg. C.

Title: Moulding prodn. with outer top skin - using top mould tool with vertical sides, pressing moulding material against top skin, and moving sliding tool in, to engage skin at sides
Inventor: KAPITAEN ENGELBERT
IPC: B29C70/78
Filed: 1991-06-21
Abstract: A plastic moulding is produced with an outer skin by placing the skin between top and bottom mould tools and pressing the moulding material against the skin by means of an integral punch tool, so that at least one rim part of the moulding is basically aligned in the demoulding direction. In this rim area the skin is gripped in an L-section by means of a sliding tool held between the top and bottom mould tools. The outer skin is pressed by the moulding material and the lower punch tool once the skin is in position between the upper and lower tools. When the upper tool has been moved down as far as possible the punch presses upwards. The top of the punch lies against the mould shot. The outer rim of the mould is in the direction of movement of the mould opening and the rim is completely covered by the skin. The sliding member engages the skin to fold it inwards. ADVANTAGE - Produces mouldings which are free from leaked quantities of material round the edge

Patent DE-4127082-A1 (DE)
Inventor: KORB DANIEL
IPC: A47B13/06
Filed: 1991-08-16
Abstract: The invention relates to a work or office table having two pairs of bearing arms which are mounted pivotably on a cross-member (10) of the table frame. In this case, the bearing arms are composed of two bearing-arm halves which, with grooves, each surround a web of the cross-member in such a way that the bearing arm can be held captively but adjusted within a given pivot angle. In this case, a clearly retainable setting of the bearing arms in the pivoted position set is maintained in a simple manner due to the fact that at least one bearing-arm half of each bearing arm is provided with a tooth gearing in the region of the groove, that the segment element (12) bears a mating gearing which engages with said tooth gearing (14) of the bearing-arm half, and that a prestressed elastic element is provided, which pulls the bearing-arm halves (20) - (21) towards one another when the screw connection is loosened and maintains the operative connection of the tooth gearing and mating gearing in a variable manner due to limited resilience.

Title: Measuring throughput of one=phase or two=phase flow - by measuring temp. flow speed and pressure and determining phase components from timing of detection of electromagnetic or acoustic waves
Inventor: SELIC HEINZ DR
IPC: G01F1/74
Filed: 1991-12-10
Abstract: The method involves measuring the temp., flow speed and pressure of the flowing medium. Electromagnetic or acoustic waves are transmitted (14) into the medium and received (18) from it. The component of gas or liquid in the flow is determined from the duration and number of the time intervals during which the waves are detected within a given period. A constant for the medium is derived from the measured components and their known material constants and is used with the measured temp. and pressure to determine the speed and throughput of the medium. USE/ADVANTAGE - Enables exact measurement of the throughput of a medium, e.g. liq. hydrogen, flowing in one and in two (gas or liquid) phases.

Title: Method for stretch-reducing of steel rolling mill loops - is used in multi-stand mill, each succeeding stand moves at higher speed than previous one
Inventor: WASSEN HANS
IPC: B23K15/00
Filed: 1992-02-29
Abstract: The ends of steel loops are edged, calibrated, upset, and the loops are then joint into long lengths, perhaps into continuous lengths, by electron-beam welding. The loop lengths are then moved to the stretch-reducing rolling mill. End calibration produces reproducible even loop ends. The loops can be produced cold or warm. Increased wall thickness also protects against tearing off in the mill. The upset wall sections help to identify joints after the stretch-reducing. Other similar welding processes may be used. USE/ADVANTAGE - Prevents thickened ends during stretch-reducing, internal surface of loops remains free of folds.
