Inventor: JAKOB RAINER DIPL ING
IPC: F24D19/10
Filed: 1989-09-28
Abstract: The central heating has a two-print control with a variable switching difference, increased in dependence on the respective power requirements towards the lower power regions.

Title: Electrically-operated pump regulation system - corrects rotation rate of electric pump motor dependent on measured flow velocity
Inventor: HENNEL EWALD
IPC: G05D7/06
Filed: 1990-02-28
Abstract: The pump regulation system uses a probe (5) for measuring the flow velocity of the pumped fluid, supplying a corresp. signal to a processor (6) for corresp. adjustment of the rotation rate of the pump drive motor.

Patent DE-4018649-A1 (DE)
Inventor: CLASEN HERMANN DIPL CHEM DR
IPC: C25D17/14
Filed: 1990-06-11
Abstract: In order to avoid corrosion damage in the non-bath galvanizing , using hand-held electrodes, of e.g. iron adjacent to masonry, aqueous ammonia is used as the starting electrolyte and zinc as the cathode, so that only inert zinc oxide and no corrosive salts remain behind after drying. Several hand-held rub electrodes are described which render possible the use in practice of the new, simple, low-conductivity electrolyte. In the simplest case, the hand-held electrode comprises a piece of zinc wire (1) 3 mm in diameter and 40 mm long, one half of which passes hermetically (3) through the bottom of a soft plastics beaker (2) 5 mm wide so that the rim of the beaker extends 2 mm beyond the end of the wire, the free end of the wire being connected to positive (4), and the beaker holding the electrolyte (E). The electrode with its bevelled mouth can be used equally well in any position. It gives about 40 mA at 12 V, and one fill lasts for more than 5 min. Zinc plated on to polished iron (5) adheres and covers well, is ductile and is suitable for the direct application of a paint coating.

Title: Measuring to derive. stream velocity vectors and temp. distribution - using heat dissipating element(s) in stream, temp. sensors and data processing evaluation unit
Inventor: HERRMANN PETER
IPC: G01P5/10
Filed: 1990-08-09
Abstract: The measuring method is applied to ascertain flow velocity vectors and temp. distribution of flow surfaces subjected to uneven streams. The surface is measuring line-wise. A measurement value proportional to the complete heat current produced along the length of a heat-generating element, e.g. heating wire (6), extending straight over the surface, is derived. Temp. sensors (2) are distributed in pairs at measuring points along the heat-generating element to derive temperatures in the direction of flow or current components. The current speed in the region of the separate sensor pairs is calculated by iteration of measurement values proportional to the complete heat current and the separately measured temperatures in an evaluation unit. USE/ADVANTAGE - Aerodynamics of body subjected to throughflow, e.g. motor vehicle cooler or radiator, to ensure optimum heat exchange. Reduced equipment, calibration and test time. Limited sensitivity to interference effects.

Title: Oxygen@ enrichment process for combustion air - is used for engines and fire-boxes, using reversible oxygen sorbent esp. per:fluorocarbon
Inventor: LUDERER FRANK
IPC: F02M25/12
Filed: 1991-05-29
Abstract: Oxygen enrichment of air in the combustion circuits of mobile and stationary I.C. engines and fireboxes is achieved using chemical substances or mixts. which, when subjected to a pressure gradient or combined pressure and temp. difference, reversibly absorb oxygen from the ambient air and release oxygen for complete combustion of fuels. The substances are pref. perfluorocarbons, iron chelate complexes, haemoglobins and certain cobalt complexes. Equipment for carrying out the process in mobile i.c. engines includes a closed pipe system in which (i) air, compressed by an exhaust turbo-charger or blower (i), is passed to a gas-permeable membrane (2); (ii) absorbed oxygen is released through a gas-permeable layer (4) near the engine; and (iii) the engine heat is extracted by the perfluoro-carbon in the cylinder walls (9) and released to ambient by cooling fins (11) ahead of the membrane (2). ADVANTAGE - The process provides simple and effective high oxygen enrichment of combustion air in a reversible continuous manner, can employ the chemical substance as the coolant (so that an additional cooling circuit is not needed), avoids the need for exhaust catalysts and allows the engine size to be considerably reduced.
