Patent SE-8206072-D0 (SE)
Inventor: BAX A M
IPC: H02P25/02
Filed: 1982-10-26
Abstract: A gyroscope motor control system has a phase-locked loop circuit and an antihunting circuit. The phase-locked loop circuit has a voltage-controlled oscillator which produces the drive signal for the motor. The frequency of the oscillator is controlled by the output of a phase discriminator which is in turn dependent on the difference in phase between a reference frequency and a feedback signal from the motor drive signal. A capacitive pick-off senses the speed of rotation of the gyroscope inertia wheel and a signal in response to this speed is supplied to a directional phase discriminator together with the feedback signal. The output of the discriminator varies with change in phase difference between its two inputs, and is supplied via a switching transistor to the input of the oscillator to effect minor variations in its frequency such as to reduce fluctuations in motor speed. The transistor is held off until there is substantial synchronism with the motor drive signal and the inertia wheel speed.

Abstract: The method is for automatically advancing a carrier tape bearing a row of closely arranged self-adhesive labels. It is used to accurately place one label at a time in a position for printing text on the label and/or to affix the label to an article. The carrier tape is drawn forwards by motor-driven feed rollers (34) which temporarily halt the tape each time it moves through a distance corresponding to the length of a label. - During its passage between a storage reel and the feed rollers, the tape is caused to pass over and to drive a freely rotatable roller without slipping or sliding. The rotary movement of this roller is sensed and used to control the feed rollers.(1/3)

The lower part (11) has a height equal to the distance between the upper edge of the lower side and the lowest normal water level (15) through which the displacement lift buoyancy is held constant. An upper part (12) in the barge has a height (H), that exceeds the difference between the low water level (15) and the high water level (19), and is equipped with connectable openings (20) in its sideboard setting, so that changes in the water-level above the lowest water level (15) do not change the barge's displacement lift buoyancy.<IMAGE>

Abstract: A pellet-sintering bed has a conveyor (1) of constant speed (v) delivering the raw pellets to a metering belt (4) pref. running at double this speed (2v). The metering belt is mounted on a truck travelling in one direction (3) pref. at the same speed as the bed conveyor. - The raw pallets fall onto a transverse conveyor belt (5) for further transport, e.g. to a rolling sieve. When the truck travels in the reverse direction, the metering belt stops, so that no pellets are delivered to the transverse belt during the return movement of the truck. The drive to the metering conveyor restarts on completion of the return stroke, the process being repeated as the truck travels in the original direction. (Dwg.No.1)

By setting means (701, 702), it is possible to control either both the pressure level of a pressure limiting unit (260) maximizing the maximum permissible working pressure and the pressure control level (p2) of the pump system (100), or only the pressure control level (p2) of the pump system (100). The setting means (701, 702) are supplied with the power signal D from a pressure level setting unit (700). The power signal D may alternatively also be used for simultaneously actuating a valve arrangement by means of which switching is effected to a certain type of digging or transport speed (e.g. low/high speed). Alternatively, the pressure level setting unit (700) is supplied with signals [Z] representing the position of the working equipment relative to the horizontal plane.

A transmitting and receiving part (1) transmits and receives the electromagnetic radiation, and a reflecting part (2) reflects the transmitted electromagnetic radiation back to the transmitting and receiving part while passing through a medium which transmits radiation. The transmitting and receiving part has an electromagnetic radiation source (5) and a concave main reflector (3) which is common to transmission and reception. The transmitting and receiving part has a second reflector (6), which is positioned between the radiation source (5) and the main reflector (3), so that this second reflector shades a part of the main reflector reflecting area (4) for the radiation transmitted by the radiation source towards the main reflector. This forms a shadow area (17) on the main reflector reflecting area for transmitted radiation. This second reflector receives a part of the reflected radiation from the main reflector and reflects this back towards a detector for reception of the radiation. The shadow area for transmitted radiation also has a reflecting receiving area for the radiation which is incident upon the main reflector and reflected back towards the detector by the second reflector. The remaining part of the main reflector reflecting area, which is not shadow area for transmitted radiation, forms a transmitting area for the radiation which is transmitted by the radiation source and reflected in the main reflector.

Abstract: The method involves adhesion of inorganic adsorber particles (5) with an average micro-pore dia. of 4 - 6A on a surface of a plate (14) by means of an adhesive layer (2). The plate is then corrugated, with a wave height of 1 - 2.6 mm, and a wave length of 2.5-5mm. Alternating lamination is then effected using a flat plate and one corrugated to form a component with several narrow channels. The inorganic adsorber is a hydrophilic zeolite, and its particles (5) are so adhered that they are partly implanted in the adhesive layer (2), with another part projecting outwards. They are blown on to the adhesive layer which by prior heating is semi-dry, so that they provisionally adhere. The layer and particles are then heated to a temp. of 100 - 250 deg. C., so that the adhesive hardens, and this during a short period so that the micropores of the adsorber are not blocked by the adhesive. USE - To produce a component for a total heat energy exchanger.

Abstract: The invention relates to a method for maintaining a nominal working temperature of the flue gases in a PFBC power plant during partial load operation of the plant by arranging firing of a complementary fuel in the flue gases downstream of the uppermost tubes in the bed. This firing is achieved by injecting a fuel, mixing it well into the flue gases, and igniting it. By the combustion of the complementary fuel, the temperature of flue gases leaving the combustor is raised to the nominal working temperature of the flue gases. During continuous combustion of a complementary fuel downstream of the uppermost tubes in the bed, this method also makes possible an optimization of temperature levels for the bed and the flue gases by allowing these levels to deviate somewhat from one another.
