Abstract: The compressor pumps air past the cold sides of the thermo elements, then aspirates air, which it then pumps to the other sides of the thermo elements, for discharge through a valve. The first thermo element cools air with its cold side, and the second element warms it again with its cold side which is then cooled. Thus, air is passed to the compressor which increases its pressure, so that it warms the warm sides of the thermo elements, the first thermo element warming the second element warm side when it is at a lower voltage in relation to the temp. difference than the second element. - The heat collection does not primarily cool the close environment, but takes in radiated heat which would otherwise be lost into space. Cold air from the generator is conducted upwards to a dark ceiling where it is heated as the ceiling cools, absorbing more heat radiation than it emits to the higher air layers. Solar energy is collected by a black roof close to the ceiling. (Provisional basic advised week 90/19) (4pp Dwg.No.0/0

Abstract: A piston engine 1, the crankshaft of which can be rotated by means of a starter motor 3, is started by the starter motor being switched off in a position in which one of the pistons is performing a compression stroke, so that the engine, by its own inertia, takes the piston past the upper dead centre. The starter motor is then restarted so as to repeat the operation with another piston. In an engine with an ignition system and an electric starter motor, the ignition spark release takes place while the starter motor is switched off. A suitable arrangement for carrying out starting is also proposed. <IMAGE>

Abstract: A suction unit sets the medium coming in through the intake into movement, causing it to pass downwards through the vessel, and out through the outlet. The primary intake comprises a number of symmetrically positioned, inclinedly directed holes in the wall of the vessel, causing the formation of a swirl with straight characteristics through the vessel central, long and narrow part with avoidance of turbulence currents. The wall holes also initiate the direction of rotation of the movable medium downwards through the vessel. - In the upper narrow part of the vessel is a secondary intake with hyperbolic and rotation-symmetrical shape, which is for mixing gas with the medium, and is displaceable height-wise. This secondary intake is long and narrow, and has its lower part nearest the vessel shaped hyperbolically and rotation-symmetrically. It evolves into a cylindrical tubular shape located further from the vessel.

Abstract: A material separating apparatus for separating particles up to a preselected size from a material having particles of different sizes therein includes a trough having a material input end longitudinally spaced from a material discharge end. The apparatus also includes a separator having a plurality of longitudinally spaced finger screen sections between the input end and the discharge end and along the longitudinal axis of the trough. The finger screen sections each have a backbone extending from side to side across the width of the trough and also each have forwardly extending fingers connected at one end to the backbone. The fingers are spaced side by side from each other by a preselected amount at forward ends thereof sufficient to allow particles up to the preselected size to pass through the fingers as the trough is vibrated to cause the material to move from the input end to the discharge end. The finger screen devices also each have the forward ends of the fingers thereof overlapping the next forwardly adjacent finger screen device and include a rearwardly depending leg connected at one end to the backbone thereof. The apparatus further includes the forward ends of the fingers being vertically spaced above the next forwardly adjacent finger screen device by an amount equal to the preselected amount of spacing therebetween. With this arrangement, the material is conveyed along therethrough and over successive ones of the finger screen sections with particles up to the preselected size falling through the finger screen sections as the material moves from the input end to the discharge end of the trough.

Abstract: The invention relates to a method of coding a sampled speech signal vector by selecting an optimal axcitation vector in an adaptive code book (100). This optimal excitation vector is obtained by maximizing the energy normalized square of the cross correlation between the convolution (102) of the excitation vectors with the impulse response (hw(n)) of a linear filter and the speech signal vector. Before the convolution the vectors of the code book (100) are block normalized (200) with respect to the vector component largest in magnitude. In a similar way the speech signal vector (s(n)) is block normalized (202) with respect to its component largest in magnitude. Calculated values for the squared cross correlation CI and the energy EI and corresponding values CM, EM for the best excitation vector so far are divided into a mantissa and a scaling factor with a limited number of scaling levels. The number of levels can be different for squared cross correlation and energy. During the calculation of the products CI.EM and EI.CM, which are used for determining the optimal excitation vector, the respective mantissas are multiplied and a seperate scaling factor calculation is performed. <IMAGE>

Abstract: The disclosure relates to a method of producing bottle or tube-like, capped packages from a polymer material which is plastically formable in the heated state. In the forming operation, a sheet (7) of polymer material heated to plasticity is fixedly clamped over the aperture (2) of a conically shaped cavity (1) corresponding to the form and size of the produced packaging container. The plastic sheet (7) is pressed into the cavity (1) by means of a mandrel (9) at the same time as blades or vanes (10) supported by the mandrel (9) are folded out in the radial direction from the mandrel (9) and urge the plastic polymer material against the walls (3) of the cavity (1), the walls being provided with channels or slots which may be placed in communication with a vacuum source. The forward portion (11) of the mandrel (9) forces parts of the polymer material into a cap (5) disposed in the innermost region of the cavity (1), with which cap the polymer material can be united. Finally, the hollow body (4) formed from the polymer material is removed from the cavity (1), filled with its intended contents and sealed by means of a preformed bottom portion (12).

Abstract: The present invention relates to a method at a mobile telecommunications system which allows evaluation of antenna tiltings by means of utilization of statistical data from CTR-measurements or corresponding measurements. From these CTR-measurements one obtains measurement values of the signal strength in both uplink and downlink, and values of TA. By converting geographical distances into TA-units one can make statistics of the average signal strength distributed per TA. This is made both before and after the tilting. By reading the statistics one consequently gets a picture of how the tilting has changed the coverage area of the base station.

Abstract: An analogue and/or digital control system is used to improve the precision and control of the movement of hydraulic or pneumatic cylinders (40) using on-off and/or proportional type electromagnetic valves (38, 39). A pulse width-modulated signal generated by a control circuit (1, 2) is regulated by a CPU (28) programmed to divide the signals into a suitable number of signal portions, so that the two electromagnetic valves controlling the cylinder can be opened and closed very quickly. An optical coupling circuit (33, 36) is present between the control circuit exit at the CPU and each transistor (34, 37). The transistors include an electronically activated light-emitting component connected to a power circuit (32), resulting in emitted light that is modulated by the pulse width-modulated signal, and this is received by a light-sensitive component without an external power source in order for the component to generate an exit signal in the form of a voltage modulated by the pulse width-modulated signal. This exit signal is applied as a control voltage between the control electrodes and sources in each of the transistors. Electromagnetic valve pre-magnetisation and pulse control allow high precision cylinder movement and also enable cylinder movement to be quickly reversed in order to oppose forces that can act on the cylinder when it is at rest or moving in a single- or twin-action system.
