Abstract: 1536018 High voltage D.C. power transmission SIEMENS AG 22 April 1976 [28 April 1975] 07117/76 Heading H2F In a control system for controlling the transmission of D.C. between a rectifier and a plurality of inverters, a first control circuit 2, 3 includes a computing circuit 2 which provides a control signal for determining the output voltage of the rectifier in response to a signal 1 representing the available power or current on the A.C. side in conjunction with a predeterminable current-voltage characteristic. A plurality of second controllers (one of which is shown in Fig. 2) for the respective inverters, each has a computing circuit 11, responsive to the value of the D.C. voltage (which provides an indication of the rectifier output capacity) and which is modified in accordance with a predeterminable voltage-current characteristic. The output of each computing circuit 11 is fed to one input of a comparator 16 the other input of which is supplied with a signal 17 representing the required energy for the respective inverter. Comparator 16 selects the smaller of the signals from 11 and 17 so as to provide a current-controlling signal for the inverter 14. As described, a signal 1 represents the current or power available in a power plant or on an A.C. transmission system. Signal 1 is added at 3 to a current margin signal Im and fed to a current controller 4 for the rectifier 5. Signal 1 is also modified by means of a computing circuit 2 in accordance with the required current-voltage characteristic and then further modified at 8 to take into account the voltage dropped in the D.C. line which is derived by a current sensor 9 and multiplier 8 before being fed to a voltage controller 6. A selector 10 allows the rectifier 5 to be controlled by whichever system 4 or 6 has the lower output. Each inverter 14 has a current controller 15 responsive to the output of a comparator 16 which selects the lower of two signals, one, 17 of which selects the desired power for the inverter 14 while the other is derived at 12 from the D.C. line voltage to which is added a D.C. line voltage drop signal from a multiplier 13. The signal from 12 is modified by a computing circuit 11 in accordance with a predeterminable voltagecurrent characteristic before being fed via an adder 19 in which the surplus difference value can be inserted from another inverter, to the other input of the comparator 16. A subtractor 18 subtracts from the output of stage 11 a signal proportional to the inverter current so as to provide a difference signal for a further inverter.

Abstract: A method is provided for assessing the strength of a concrete structure by determining the flexural strength at a test section at the base of a concrete core projection established by disposing a tubular form element in the freshly poured and levelled concrete and removing the tubular form when the concrete has hardened sufficiently. A special load cell is inserted in the surface opening of the slit left in the concrete by the tubular form and the load cell activated to apply a recordable, gradually increasing force to the top of the core projection until rupture occurs at the base of the core projection. The flexural strength of the test section is then derived from recordings of the applied force at the moment of rupture.

Abstract: An apparatus for discharging lump ice or so-called shell ice is of the type that comprises a pivotable conveyor 7, consisting of an endless belt, with grabs 8, driven by a first drive element. The pivoting movement of the conveyor is adjusted by means of a second drive element 9, which is designed to adjust the pivoted position of the conveyor as a function of the power loading on the first drive element, so that this power loading is kept constant during the discharging of lump ice. In an improved design, the power loading on the first drive element is allowed to increase with the rising inclination of the conveyor. Account is thus taken of the increased power required in order to convey released lumps of ice to a discharging point, situated higher up. <IMAGE>

Abstract: A dosing valve comprising a housing (1) having an inlet port (4) and an outlet port (5) and divided internally into first and second chambers (18 and 14) by a movable member (6) having an elastically deformable portion (11). The first chamber (18) is in permanent communication with the inlet (4), and the second chamber communicates with the outlet (5) via a spring loaded non-return valve (19), which is adapted to be closed by movement of the movable member towards the outlet and to be opened when the pressure in the second chamber (14) reaches a predetermined level. The first and second chambers are arranged to communicate via a control port (15, 16) which is adapted to be closed by movement of the movable member (6) towards the outlet (5). In operation, with the valve filled with fluid at low pressure, an increase in pressure at the inlet causes the movable member (6) to move towards the outlet (5) so as to shut off the control port (15, 16) between the chambers and the outlet valve (19, 20), and a further increase in inlet pressure and therefore in the first chamber causes the elastically deformable portion (11) to deform so as to pressurise the second chamber and thereby open the outlet valve to deliver the dose defined by the second chamber (14). <IMAGE>

Abstract: An object is produced from a tubular blank (10,15,17) of thermoplastic material of polyester or polyamide, preferably of polyethylene terephthalate by reducing the thickness of amorphous material in one or several areas of the blank by means of one or several consecutive re-shaping operations. A mechanical shaping device (23,29,71,81) moves a transitional zone (13,14,113) situated between thicker and thinner material along the blank and simultaneously elongates the blank in the moving direction of the transitional zone while reducing the thickness. After the last re-shaping operation the thinner material preferably has an oriented state. During the re-shaping operation the temperature of the material in the transitional zone (13,14,113) is controlled at a level which, immediately before the re-shaping operation, is within or close to the range of the glass transition temperature (TG). In one embodiment the reduction of the wall thickness of the material is begun in a track (12) in the wall of the blank and continues symmetrically around the track. Clamping devices (41,51,61) are used to maintain the axial position of the blank. The blank is suitable for re-shaping, for instance, into a container in which the mouth also consists of oriented material.

Abstract: In an internal combustion engine with an exhaust turbocharger, a bypass line is provided between the intake pipe connected to the charger and situated downstream of the throttle valve and the exhaust pipe opening into the turbine. Arranged in the bypass line is a valve which shuts off the bypass line only when the exhaust gas pressure in the exhaust pipe exceeds the charging pressure in the intake pipe by a certain amount and a connection is having a disadvantageous effect on the performance of the internal combustion engine. Below this pressure range, the valve is open and the connection between the intake pipe and the exhaust pipe is free. In the operating condition of the internal combustion engine in which the charging pressure is higher than the exhaust gas pressure, it is thereby possible for fresh gas from the intake pipe to pass into the exhaust pipe and for automatic supplying of secondary air to take place. If, on the other hand, the exhaust gas pressure is higher than the charging pressure, exhaust gas flows across from the exhaust pipe into the intake pipe, automatic exhaust gas recirculation thus taking place.

Abstract: PURPOSE:To obtain an extremely smooth and little wavy interpolation curve by selecting clothoid curves, connecting some of these and making a tangent direction and a curvature on the connecting points continuous. CONSTITUTION:When the coordinates of two points P1 and P2, and a curvature Cv1 and a tangent direction phi1 of the P1 pint are given, one or two clothoid curves to pass these two pints can be drawn. When the position of the P2 point is reasonable, one, and when it is an unreachable position, two clothoid curves are connected as the continuity of a CV and a phi. Even at the time of more than three point, when a point spring itself is smooth, they can be connected by one clothed. Thus, for example, when an illustrated point string 1-12 is given, these points can be connected. On a figure to show the broken-line of the CV to obtain a first approximate value, one straight line is equivalent to one clothoid. The first approximate value of the CV makes the curvature of a circle passing three points including the front and the rear points into the curvature of the point. A circular interpolation is executed to one part between points 5 and 6 and a straight-line interpolation is executed to one part between points 11 and 12.

Abstract: The invention provides a method of making a composite beta-alumina artifact, such as a separator tube for an electrochemical cell, comprising two beta-alumina portions which are sealed together in a sealing zone, namely an inner portion and an outer portion which extends peripherally around the inner portion and embraces it in the sealing zone. The method comprises pressing the inner and outer portions from powders which, when sintered, shrink and form integral beta-alumina artifacts. The portions are then arranged so that the outer portion extends around the inner portion and embraces it in a sealing zone. The portions are then sintered to cause them to seal together hermetically in the sealing zone while converting each of the portions into a beta-alumina artifact. The portions are made so that the outer portion undergoes a greater degree of shrinkage during sintering than the inner portion and the portions are pressed so that the spacing between the portions where the outer portion extends around and embraces the inner portion is such that, upon sintering, the outer portion shrinks on to the inner portion to provide a hermetic peripheral seal between the portions.
