Patent DE-3222269-A1 (DE)
Title: Method for controlling and regulating a synchronous machine
Inventor: HUSSELS PETER DIPL ING
IPC: H02P21/10
Filed: 1982-06-10
Abstract: In a method for controlling and regulating a synchronous machine which is operated on the converter and has indirect flux orientation, that is to say the flux position which is required for control being calculated from the rotor position and from the reference variables for the currents, and the components of the actual flux value being additionally determined from the terminal voltage and current, the object exists of being able to dispense with the use of a rotor position sensor. This is achieved in that, with the aid of a co-ordinate rotator (3'), the co-ordinates ( psi m,  psi i) of the actual flux value ( psi  alpha ,  psi  beta ) are determined with respect to the previously calculated position of the flux, in that the deviation of the m-component of the flux vector from the reference value  psi  is supplied to a first flux regulator (11a) whose output signal is added to the reference value for the excitation current, in that, in order to determine the rotor position (cos  lambda , sin  lambda ), either a tachogenerator (4') with a sine-cosine generator (12) connected to its output, or only one of the latter is used, a suitably controlled predetermination of the angular speed ( omega o) being made when starting from zero speed, and in that the deviation of the l-component of the flux from the value zero is supplied to a second flux regulator (orientation regulator 11b), whose output signal is likewise supplied to the sine-cosine generator (12) - additively to the predetermined angular speed value with respect to the tachogenerator signal. <IMAGE>

Title: Tobacco smoke filter
Inventor: HAYES ERNEST BRIAN
IPC: A24D3/04
Filed: 1982-07-05
Abstract: Tobacco smoke filters are described which initially have flow passages of relatively low and relatively high pressure drop for the smoke passing through. Transversely to the, or each, flow passage of low pressure drop, a barrier is arranged, which is initially permeable to smoke but becomes blocked or clogged by the smoke passing through, so that the smoke initially flowing through the flow passage or the flow passages of low pressure drop causes the blocking thereof and the passage of smoke through the flow passage or the flow passages of high pressure drop is thus correspondingly increased.

Title: Filter having plastic housing for air purification
Inventor: KECK HERMANN DR
IPC: B01D46/00
Filed: 1982-09-23
Abstract: Two perforated plastic tubes concentrically mounted one inside the other are held together at both ends by welded-on plastic rings. Contaminated air is blown into the housing at the front open ring. Since the rear end of the filter is sealed, the air must escape laterally through the holes in the tubes. The air is thus forced past adsorbing or absorbing materials packed into the space between the two tubes and is purified as a result. These filters having a plastic housing have the advantage that they do not corrode. The mounting on the filter wall can be achieved either by screws or by threaded connectors, or by a rod passing through. The length of the filter housing and thus the capacity can be varied according to requirement.   <IMAGE>

Title: Thermostat time switch
Inventor: GRIES DOMINIQUE DIPL ING
IPC: G05D23/275
Filed: 1982-11-10
Abstract: In a thermostat time switch (1) having a changeover device (2) which can be manually actuated between the operating modes of permanent day-time management, permanent night-time drop-down and time-controlled reversal between day-time management and night-time drop-down, the aim is to specify a design which can be installed in a cost-effective fashion for the purpose of heating control and is small and of low complexity in terms of apparatus and the way it functions. It is provided for this purpose that the position of a temperature sensor (20) which experiences a temperature-dependent change in shape can be adjusted mechanically with respect to an interruptor to be actuated by it in accordance with the instantaneous position of the changeover handle (36), the change in position of a temperature sensor (20) being performed by means of a lever linkage (lever 14 with supporting arm 35) via support surfaces (wedge-shaped abutment 30, sloping support surface 38) which are inclined with respect to the particular movement. In the case of operation with permanent night-time drop-down, the position of the changeover device (2) determines the temperature difference with respect to the prescribed day-time management temperature, while by switching over to permanent day-time management the night-time drop-down displacement of the temperature sensor (38) is compensated once again, so that the day-time temperature setting on the scale (11) once again applies. For the purpose of operational connection in the case of the last-mentioned changeover, it is preferable for a geared coupling of the type of a Maltese cross gear (pin 48 and slot 46 between ...

Title: Method and device for detecting flow rates of fluid media conducted through pipelines
Inventor: RUMP GEORG F
IPC: F24D19/10
Filed: 1982-12-02
Abstract: In a method for detecting the flow rates per unit of time of fluid media conducted through pipelines, the flow rate control being performed by at least one shut-off member inserted into the pipeline, for the purpose of easing the measured value acquisition and of reducing the installation expenditure it is proposed that the position of the shut-off member is detected and converted into an electrical signal, the pressure difference produced in the pipeline at the shut-off member is detected and converted into an electrical signal, the respective temporal period of the release of a defined flow cross-section and of a defined pressure difference is detected and converted into electrical signals, and the electrical signals thus generated are fed to an electronic logic element, combined, displayed, summed and once again displayed. <IMAGE>
Patent DE-3302065-A1 (DE)
Title: Sorption heat pump
Inventor: KANTNER ALEXANDER DR
IPC: F24D19/10
Filed: 1983-01-22
Abstract: The present invention relates to a sorption heat pump with a stripper, condenser, expansion points, an evaporator and also an absorber. In a control system for such a heat pump, for example an absorption heat pump for supplying the central heating system of a detached house, the fuel throughput of the burner heating the stripper and the throughput of solvent for feeding the stripper can be taken as reference values. In order to avoid infinite adjustment of both throughputs, it is expedient to adjust the throughput of solvent into the strippers stepwise, and to override the intermediate positions of these steps by an adjustment of the throughput in the fuel path. In this manner, a continuous adjusting valve or a continuously controllable solvent pump can be done away with.

Patent DE-3303629-A1 (DE)
Title: Method for the production of a cam shaft with at least one eccentric cam
Inventor: NAKAMURA MASANOBU
IPC: B21D53/84
Filed: 1983-02-03
Abstract: To produce a cam shaft by expansion, depressions are formed in a tubular starting material at points where annular parts are to be mounted on the starting tube. The depressions are formed before the starting tube is expanded in a suitable dye together with the annular parts. These depressions are advantageous particularly if the width of the annular parts is not uniform, since such depressions make possible the use of annular parts of relatively great thickness even in areas with a small radius, thereby solving the known problem that annular elements have a tendency to crack in areas with a small radius. Such a cam shaft can also be produced from a hollow tube and short cylinders with essentially the same outside and inside dimensions as the cams of the cam shaft. The hollow tube is preshaped at the desired points before expansion at the end, the hollow tube thus being provided with dimensions and shapes which correspond to those of the short cylinders. A relatively small degree of expansion of the hollow tube during expansion at the end is therefore required. The inclusion of such a preshaping step is advantageous since the hollow tube can be easily made to form a leakproof or tight fit with the entire inner wall of each short cylinder even if the short cylinder has a long and sharp projection.

Title: Spacer for attaching a surface element or element carrier to a housing wall
Inventor: KOEGEL ARTUR
IPC: H05K7/14
Filed: 1983-04-02
Abstract: Spacers for the attachment of a surface element, such as a fitted printed-circuit board, in an apparatus housing are known in diverse configurations. Expanding nuts are preferably used for this purpose, which are inserted in a perforation in the housing wall and whose height is dimensioned such that the surface elements which are attached on the spacer are arranged at a specific distance from the housing wall. Expanding nuts and other latching connectors can slide out of the perforations in the housing wall in the event of extremely severe mechanical stress, or the screws which are screwed in in order to attach the surface elements project from said perforations, so that additional electric-shock protection must be fitted. According to the invention, a spacer consisting of a bearing block with rigid projections placed thereon is used, which bearing block can be inserted in a perforation in the housing wall such that it can be displaced, the guide groove formed by the projections being capable of being pushed onto the housing wall. The spacer is protected against rearward thrust by means of an additional catch, so that the spacer is attached in the perforation in the housing wall by means of a sliding-latching connection. The projections prevent the spacer sliding out at right angles to the housing wall, even in the event of extreme mechanical stress.

Abstract: Die bekannten Vorrichtungen zum Trennen von Glasfasern, bei denen die Glasfasern zumindest an der zu trennenden Stelle parallel über einen Amboß (1) geführt und durch eine senkrecht zu den Glasfasern (2) wirkende Spannvorrichtung axial vorgespannt und anschließend auf dem Amboß (1) geritzt werden, haben den Nachteil, daß dei Bruchflächenqualität großen Schwankungen unterworfen ist. In der Regel sind nur 30% so beschaffen, daß die Winkelabweichung weniger als 1 Grad zur Faserachse beträgt und deren Bruchflächenqualität frei von störenden Kerben, Rissen und sonstigen Unebenheiten ist. Gemäß der Erfindung kann die Ausschußquote ganz erheblich dadurch reduziert werden, daß in dem Amboß (1) ein Schlitz (12) vorgesehen ist. der symetrisch zur Ritzebene verläuft, wodurch an der Ritzstel Einfügung                                                                     le eine symmetrische Spannungsverteilung im Glasfaserquerschnitt erreicht wird. Die Bemessung der Breite (B) des Schlitzes (12) richtet sich dabei nach dem Durchmesser (D) einer zu trennenden Glasfaser (2). So wurden sehr gute Ergebnisse erzielt, wenn für das Größenverhältnis D/B von dem Durchmesser (D) einer zu trennden Glasfaser (2) zu der Breite (b) des Schlitzes (12) Werte zwischen D/B = 0.125 und D/B =0.25 eingehalten werden. Optimale Ergebnisse werden erzielt, wenn das Größenverhältnis D/B zwischen D/B =0.15 und D/B =0.16 festgelegt wird.   Änderung

Title: Method of rapidly determining the degree of ethoxylation of highly ethoxylated nonionic surfactants
Inventor: BECK RUDLF
IPC: G01N25/02
Filed: 1983-10-06
Abstract: In a rapid determination of the degree of ethoxylation of highly ethoxylated nonionic surfactants, a mixture is prepared of 20 to 50% by weight of a highly ethoxylated nonionic surfactant and 80 to 50% by weight of two hydrophobic organic solvents, one of which produces a clear solution of the surfactant and the other produces a turbidity when mixed with the surfactant. The solvent producing a clear solution is used in a ratio by weight of 50:50 to 20:80 to the hydrophobic solvent producing a turbid solution. The temperature is determined at which the initially turbid solution becomes clear or the solution which has become clear as a result of heating becomes turbid. From this temperature the degree of ethoxylation is determined using a calibration curve plotted beforehand. The method can be carried out so rapidly that it can be used during the ethoxylation reaction to determine the end point of the latter.

Title: Gas permeation cell
Inventor: GALOW ERICH
IPC: B01D53/22
Filed: 1983-10-25
Abstract: The invention relates to a gas permeation cell for pressures up to 160 bar and high temperatures, comprising a trough with a cover which can be mounted thereon, a permeation membrane being arranged centrally in the trough, which membrane separates the permeate from the permeant. The object of the invention is to design a gas permeation cell of the type described above in such a manner that it is suitable itself for testing gas permeation membranes and for the economic separation of permeate. The solution is characterised by the following characteristics:     a) the permeation membrane is applied to a support,   b) collection of the permeate is carried out beneath the support, c) a seal is arranged between the cover and permeation membrane, which seal tightly separates the permeant chamber from the permeate collection chamber and   d) the cover is sealed from the trough.   The particular advantage of the permeation cell according to the invention lies in the simplicity of handling of the cells into which circular sample pieces of membranes are inserted for testing. For safety reasons, and because of any thermostating required, these membrane tests are always carried out in the water bath, so that particular attention must be paid to the sealing, since the gas membranes on, for example, water uptake, become absolutely gas-tight, and thus unsuitable for separations.
