Patent SE-7904696-L (SE)
Inventor: HEIKKILE S
IPC: G01N22/00
Filed: 1979-05-29
Abstract: A method and apparatus for detecting grain direction in wood particularly in lumber by means of high frequency radio energy like microwave radiation. The grain direction in lumber can be detected so that knots will cause no significant error to the measuring result. The knots are detected by the method according to the invention in so far as they contain deviations of grain direction. The microwave radiation is either passed through or reflected from the piece of lumber. Radiation energy is transmitted with the aid of a transmitting antenna with a certain direction of polarization and a signal of grain direction is obtained by detecting microwave field by a receiving antenna whose direction of polarization plane forms an angle of 90 DEG  with the direction of polarization plane of transmitting antenna. A preferred embodiment of the invention provides for the polarization of transmitting field to be changed so that it alternatively is parallel or perpendicular to the direction of polarization plane of receiving antenna. A first signal (Vs) is measured when both polarization planes are perpendicular to each other and a second reference signal (Vref) is measured when the polarization planes are parallel. The angle of the grain direction is obtained from the result of dividing the first signal with the sum of the first and second signals.

Abstract: In the possible case of a stop or failure of the transport of a material through an IR oven, a risk may arise of the material overheating or even inflaming, owing to the very high heating effect. Even if the current to the IR tubes 1 is cut, a certain post- radiation will continue for some time. In order to prevent said post-radiation from falling on the treated material 4, a device is according to the invention proposed, which will cause rotation of the IR tubes for half a revolution in the case where a reflective material 3 is placed on their rear side. In the case where separate reflectors are arranged at a distance from the rear side of the IR tubes, a rotation of the reflectors is caused for half a revolution around the IR tubes, whereby the radiation is directed away from the material to be treated. <IMAGE>

Abstract: A screen printer has a flat bed coplanar with a loading and an unloading surface on opposite sides thereof, the bed being divided into a stationary middle section and two movable outer sections confronting one another along boundary lines paralleling the direction of movement of copy sheets from the loading surface to the unloading surface. Such movement is effected with the aid of a conveyor comprising two chains underneath the bed entraining sheet-gripping jaws through the gaps formed between these sections when they are transversely separated. The jaws are almost flush with the plane of the bed and the loading and unloading surfaces; upon closure of the bed sections, they are received in cutouts of the outer sections and are thus immobilized while a printing screen descends into contact with a copy sheet overlying the bed.

Abstract: A plurality of arbitrarily loaded induction machines are operated from a single, controlled current inverter by regulating the amplitude of inverter output current in response to the average of the individual induction machine phase angles, the machine phase angle being the phase relationship magnitude between machine air gap flux and current, and by regulating the frequency of inverter output current in response to the average of the individual induction machine phase angle and the slip frequency of the most heavily loaded induction machine. The most heavily loaded induction machine is thus assured of having sufficient flux, thereby greatly reducing the possibility of machine pull-out and resultant inverter instability.

Abstract: Electric power amplifiers produce as a rule the output voltage by taking up the voltage between a continuous voltage and the output voltage by means of a component with controllable voltage drop. When the output voltage is an alternating voltage a transformation of the continuous voltage can instead be made by a transformer (14) with variable ratio. The position of the connecting point of the transformer winding can be controlled mechanically or electrically and the contact at the point can be attained by mechanical contact, electrons, ions or charges in semiconductors of different kind. For example electrons can be guided to determined turns on the coil by giving a cathode (16) a longitudinal voltage drop from the heating voltage (18) and by connecting the input voltage to the grid, making it possible for electrons to arrive at a part of the coil, while the voltage of the coil further limits the electron current to a small part of the coil. By means of the design of the transformer the input signal can be converted to arbitrary output signal for example harmonics and saw tooth voltage.
