Inventor: RAGALY ISTVAN DIPL ING
IPC: H02K9/02
Filed: 1990-02-03
Abstract: Proposed is an electrical machine with external air cooling, the machine housing (17, 18) having openings (32, 39, 41) for the intake and exhaust of an external cooling-air flow (40) to ensure the removal of the waste heat generated in the machine (10).

Title: Contacting device for circuit board - has facility for easy contacting from mounting side after assembly
Inventor: NERRETER WOLFGANG PROF DR ING
IPC: H05K3/34
Filed: 1990-04-24
Abstract: The device is used for contacting through bores of circuits boards. After assembly the bore  diameter is reduced on the mounting side. By a thermal treatment the contacting can be easily carried out from that side due to the shape memory effect. Thus, in addition to the increased diameter, straps are bent outwards in the region of the soldering side such that the contacting device is pressed against the circuit board, forming an electric connection between the copper film of the mounting side and the contacting device. ADVANTAGE - No need for special tools for inserting into circuit board bores.
Patent DE-4019160-A1 (DE)
Inventor: GONZE EUGENE VICTOR
IPC: F02D41/00
Filed: 1990-06-15
Abstract: A fuel control for an engine using a liquid mixture of two fuels such as gasoline and methanol derives a fuel control parameter such as a desired fuel/air ratio from the output of a fuel composition sensor in a first mode of engine operation. The value of the fuel control parameter at the end of the first mode of engine operation is locked for use throughout a second mode of engine operation including closed loop control in response to an air/fuel ratio sensor, as long as the fuel composition does not change more than a predetermined amount during the second mode. The stable operation of the fuel control in the second mode is thus protected from instabilities introduced by small insignificant fluctuations in the fuel composition signal. In an engine with adaptive learning control the adaptive learning control mode is reserved for particularly stable modes of engine operation including closed loop stoichiometric control and thus serves well as the second mode of engine operation.
Patent DE-4019900-A1 (DE)
Title: Compact ion-exchange filter - in which acid flows upwards in reverse direction through anion unit and is converted to second acid suitable for regenerating cation unit
Inventor: BLANK WINFRIED DIPL ING
IPC: B01J47/02
Filed: 1990-06-22
Abstract: An existing ion-exchange filter has a first vessel for cation-resin, a second vessel for anion-resin, and a differential conductivity measuring system. The two vessels are regenerated in sries in a reverse flow operation. Under this invention, the second vessel is upstream of the first vessel during the regneration procedure. A combined container is used to hold both vessels, the first vessel being above the second and sepd. from it by a partition penetrated by nozzles. This nozzle plate extends over the entire width of the container. The resin in both vessels is loosely packed. The second vessel is bounded on the upstream side during regeneration by a second partition with nozzles, beyond which is a pressure equalisation chamber. The second vessel is connected on the upstream side to an acid supply system which contains a mixing device provided with a regeneration-water supply and an acid measuring container. The acid used is hydrochloric or sulphuric. USE/ADVANTAGE - Used in the design of ion-exchange filters having anion and cation units. The need for two ion-exchange vessels is removed and the manufacturing cost is considerably reduced. The need for externally supplied fluids for regeneration of the resins is greatly reduced, since the acid used for regenerating the second vessel (say HCl) is converted by the regeneration process to a second acid (H2SO4) which serves to regenerate the second vessel.

Title: Continuous fermented mass prod. - in which lower component is fed into extn. vessel with a consistent mass flow speed, enabling extn. of mass material at required ripeness
IPC: A21D8/04
Filed: 1991-08-02
Abstract: To provide a continuous supply of fermented mass, such as dough for bakeries and esp. sour-dough and yeast-dough, the components are fed into a vessel from below, and the mass is given a generally consistent flow speed over the cross section surface of the vessel. The component feed and removal of the mass are set so that the vessel remains constantly full. The flow speed of the mass is set to a value which is proportional to the shear stress of the mass. Pref., a general laminary flow is developed within the vessel, at a flow speed calculated to give the mass its required ripeness at the outlet and ensure that the mass moves through during a generation time of the microorganisms. The flow speed is structured according to the deg. of ripening, the acid formation, the tackiness and/or the redn. in viscosity. ADVANTAGE - The system allows components of the mass to be taken out on a "first in first out" basis, without a tube, and also extract mass material at the required ripeness

Title: Gas prodn. from rotting organic waste material - by partly dewatering chopped wet raw material and treating with low-oxygen content fluid before entering reaction vessel
Inventor: HOBERG HEINZ PROF
IPC: C12P5/02
Filed: 1991-08-08
Abstract: In a procedure for producing gas from rotting organic material in a foul gas reactor (13), the wet mixt. of raw materials, pref.  having been chopped or ground in a wet process, is at least partly de-watered and in this way the oxygen-rich gas in the raw material is at least partly sepd.. The raw material may be rinsed with a rinsing fluid of low oxygen content in order to remove the oxygen-rich gas. Waste water from the reactor, and/or from the de-watering of the residual material from the reactor, may be used for rinsing, as also may be an exhaust gas from for example the combustion of the foul gas. The rinsing fluid (10) is passed through the solid material as it separates from the liquid in the de-watering process (9). During transport from the de-watering stage to the mashing (11), the raw material is kept under a low-oxygen gas atmos., which may be in partic. an atmos. of exhaust gas from a combustion process. USE/ADVANTAGE - Used the prodn. of gas from rotting organic material in a reactor vessel. The proposed procedure allows the dwell-time of the material in the reactor to be reduced, and also improves the degree of recovery of gas from the raw materials.
