Patent SE-7711890-L (SE)
Inventor: PITRODA S G
IPC: H04Q3/545
Filed: 1977-10-21
Abstract: A microprocessor control complex for a telecommunications switching system disclosed in the context of a digital time division multiplex switching system. The control complex is arranged as a cluster of hardware identical microprocessors in a distributed processing configuration wherein each microprocessor is provided with its own memory and clock and is programmed to perform a portion of the total function of the switching system. Each microprocessor performs the functions assigned to it independently and asynchronously of the others. Data is transferred between microprocessors in a manner which minimizes the amount of time spent in interprocessor communication. This communication is accomplished via interprocessor buffers which provide dedicated communication channels between partner processors while allowing those processors to continue to operate asynchronously. The distributed control complex allows the software to be modularized with resulting economies in program generation and debugging.

Abstract: The present invention relates to a method and a device for 180 degrees bending of a band or sheet of a flexible, deformable material. The problem with known methods and devices of said type is that the bending process is performed in two or more operational steps. The object of the present invention is to provide a folding of a band or sheet, which is performed in one operation in a sequence. Hereby, the band or sheet is clamped between a backstop 7; 7' and a tab-like protrusion 6; 6', following which the protruding edge 12a of the band or sheet 12 and an abutment 9b; 9'b are displaced relative to each other, whereby a 90 degrees bend of the edge 12a is performed, relative to the remaining portion of the band or sheet 12. Subsequently, the folding is finished by means of a bending device 9; 9', whereby the protrusion 6; 6' is in connection therewith removed from the backstop 7; 7'. <IMAGE>

Abstract: An open container which is nestable with an underlying similar container and which is provided with wedge members and one or more locking members. Each locking member on the overlying container, in response to a relative rotation of the two nested containers, will engage and ride upon a guide surface of a corresponding wedge member of the underlying container until such locking member comes into engagement with an abutment surface of such wedge member, to secure the containers in a relative angular position established thereby. Subsequent similar containers may be stacked, nested one in another, and in a similar manner, be secured in a common angular orientation.

Abstract: A system for indicating economy of operation in internal combustion engines in boats enables the setting of a specific number of revolutions for fuel economy. Two measuring devices are utilized, the output signal of one being proportional to the number of revolutions of the engine (1), whereas the output signal of the other (4) is proportional to the flow of fuel to the engine. These two signals are compared in an indicator device (6, 7, 8), which as a result exhibits at least one extreme value in the operational range, whereby it becomes possible to find a favourable number of revolutions for operation with a high degree of efficiency and to avoid numbers of revolutions with a low degree of efficiency in simple manner. <IMAGE>

Abstract: The invention relates to a screw compressor in which a slide valve element and a movable sliding stop element are provided in an axially parallel recess, open to at least one of the rotor bores, of the housing peripheral wall and are axially actuatable independently of one another. By means of the sliding stop element a return flow slot to the inlet aperture can be opened, which results in the machine running only at partial load. Different partial load capacities can be obtained by different combinations of slot size and slide valve position, but only one of these combinations provides the optimum efficiency. In order to permit operation of the compressor with high efficiency under at least two different partial load conditions, according to the invention at least one further valve element (7) is arranged inside the recess (3) between the slide valve element (5) and the sliding stop element (6), which valve element (7) can be displaced by means of its own actuating device (12) both separately between the first and the second element (5 and 6) and bearing on the first or second element to form an extension thereof. <IMAGE>

Abstract: A hydraulic control device for the pressurization of a clutch or the like for a transmission operable under load comprises a spool-type valve displaceable in one direction to pressurize the clutch and in the opposite direction to vent the same. The valve spool operates with a damping piston which receives the clutch pressure buildup and acts against a control piston which, in turn, is displaced by an operative valve. According to the invention, the pressure head is maintained substantially constant by providing a sleeve or bushing within the damping piston chamber which bears against the spool by a spring and which can be biased by a spring between the damping piston and the sleeve.

Abstract: In the conventional stacking method of the laminated core of a transformer, grain-oriented silicon steel sheet pieces of an identical grade or the identical magnetic properties are used as legs and yokes of the core. In a highly oriented silicon steel sheet having a high B8 value due to excellent magnetic properties in the rolling direction of the sheet, the excellent magnetic properties cannot be fully utilized for the watt loss reduction in the conventional stacking method. In a laminated core of the present invention, the transformer core comprises a grain-oriented silicon steel sheet having a higher orientation used for a leg(s) and a grain-oriented silicon steel sheet having a lower orientation used for a yoke(s). The former steel has the B8 value of generally 1.88 Tesla or higher and preferably 1.89 Tesla or higher. The latter steel has the B8 value of generally 1.86 Tesla or lower. A low watt loss, particularly at a low or medium magnetic flux density, can be achieved by the present invention, while decreasing the cost of the transformer.

Abstract: The primary winding of a high leakage inductance transformer is coupled to a source of alternating input voltage to develop alternating polarity output voltages across tightly coupled secondary windings, including a high voltage winding of the transformer. Various DC supply voltages, including the ultor voltage, are derived from the secondary winding output voltages. To regulate the secondary winding output voltages, a ferroresonant circuit comprising a capacitor and a saturable reactor is coupled as a load circuit to one of the transformer secondary windings. When the saturable reactor magnetically saturates during each half cycle of the alternating polarity output voltage, a circulating current is generated and flows between the saturable reactor and the capacitor. To enhance the power supply efficiency and reduce the temperature rise within the magnetizable core of the saturable reactor, the parameters of the transformer and ferroresonant load circuit are selected so as to generate a relatively low amplitude circulating current. To improve output voltage regulation when a low amplitude circulating current is developed, a compensating drive winding is provided that is magnetically tightly coupled with the primary winding of the high leakage transformer. The compensating drive winding is coupled in series with the saturable reactor winding across the capacitor and polarized relative to the capacitor coupled transformer secondary so as to oppose the tendency of the output voltage amplitude or half-cycle volt-second area to vary with variations in input voltage amplitude.

Abstract: The present invention relates to a method and to an arrangement for measuring the carrying capacity of roadways and has as its problem to make possible such measurement without damages occuring to the roadway and without its being necessary for traffic to be suspended. A large number of measurements are to be established under load conditions as close as possible to reality and at low cost. This is achieved according to the invention by the means that the elevational position of the roadway surface is measured contactlessly relative to a reference position in the first place in front of and, in the second place, directly behind a load rolling on the roadway and that the measuring values are subtracted from one another and the difference value is registered or indicated depression of the roadway surface obtained by the rolling load.
