Abstract: This invention concerns a lumber elevator which comprises at least two parallel-running transport chains with carriers to accommodate pieces of lumber from a lumber stockpile and transport of the pieces of lumber to a level higher than the lumber stockpile. In lumber elevators of this type, it often happens that several pieces of lumber and especially pieces of lumber which are stacked edge to edge on top of each other are transported, and this constitutes a problem because the goal is to only transport one piece of lumber at a time. To eliminate this problem, the invention proposes an arrangement of pushing elements 18, which in a predetermined position shoot out across the transport plane of the elevator between consecutive carriers 3 which are passing through said predetermined position, and said position lies at a distance from the rear carrier 3, looking in the direction of transport, which is greater than the width dimension of the pieces of lumber. <IMAGE>

Abstract: A device for testing and/or measuring electrically conductive material comprises means 1 for generating at least two frequencies or frequency components  omega 1- omega n which via a transmitter 2 induce a magnetic field in the material, and a control servo 5 for compensation of signals of the frequencies or frequency components derived from the transmitter 2. The compensation is such that an error signal resulting from a varying parameter such as varying lift-off, temperature or dimension is generally suppressed. This can be achieved by suppression of relatively slow signal variations but not the more rapid signal variations arising from the changes or deviations to be measured. <IMAGE>

Abstract: Method and apparatus for testing the correspondence of the line of sight of optical instruments with the target line of weapons. A predetermined measuring field and a photoelectric line-type sensor are used. The nominal positions of the lines of sight and of the target lines relative to each other are stored as coordinates in a long-time memory. Simultaneously a nominal reference point as the origin of the coordinate system stored in the long-time memory is determined. The method and apparatus are carried out in the following sequence: (a) one light-dot is generated within the measuring field per line of sight and per target line and these light-dots correspond to the actual positions of the lines relative to each other; (b) one of the light-dot is selected as the reference point (origin of the measurement coordinate system); (c) the light-dots are scanned by the sensor during a linear relative motion between the measuring field and the sensor; (d) the electric sensor output signals obtained during the scanning are compared, possibly after intermediate storage, in a computer with corresponding signals read out of the long-time memory; and (e) the signals resulting from the comparison and representing the deviation of the actual measured position from the nominal position are displayed and/or used as control criteria.

Title: Packing of a porous mass for fluid chromatography - has polymer tubes with shrink memory exerting radial pressure
Inventor: MCDONALD P D
IPC: B01D15/08
Filed: 1982-04-28
Abstract: A packaging having an elongated chamber, contains a porous mass arranged to come into intimate contact with a fluid fed through the chamber, as in high pressure liquid chromatography. The porous mass is held in the vessel at the inlet and outlet and the chamber is formed by a membrane arranged to compress the porous mass radially. The membrane rests against the porous mass sufficiently firmly by deforming and reducing the empty space between the two, without internal pressure on the membrane. The membrane is pref. of PTFE or polyethylene. Supersedes previous techniques requiring great care to prevent the settling out of particles according to size and pack the column uniformly which in any case produces a column handled with difficulty. The production of a column especially suited to liquid chromatography is facilitated, with the elimination of the relatively large empty spaces which make analytical decisions very difficult. The column can be brought under uniform pressure over its whole length so that a series of comparative tests can be made.

Inventor: DAHLIN GOSTA JOHAN
IPC: G01S5/18
Filed: 1982-06-30
Abstract: The process is for determining the position of an object, from which emanate signals in the form of wave movement transmitted in a medium. The object has sought-after coordinates in a system, and a number of microphones are grouped and mutually spaced. The distances between them are considerably greater than the wavelength of the wave movement. The microphones are grouped in known coordinate positions for probing signals at those points. After coorelation of the probed signals dependent upon their kind, the time taken for the signals to reach the microphones is measured for subsequent automatic calculation of the coordinates of the object using a computer or a calculator, programmed with an evaluation algorithm. Out of at least four grouped microphones spread out two-dimensionally in the horizontal plane two three-probe groups are selected, and the object coordinates are calculated from two mathematical equations involving the crossing points for two straight lines.

Abstract: The invention concerns a method and an apparatus for measuring the level of a material with microwave signals. The apparatus consists of a signal processing unit (10) and a transmitter unit (1) of known type. The transmitter unit produces a measuring signal having a frequency (fm) corresponding to the distance (H) to be measured and a reference signal having a frequency (fr) corresponding to an accurately known length (L). In the signal processing unit (10) the reference signal is multiplied by a selectable number (AQ) which is proportional to the quotient of an assumed value for the distance divided by the known length (L), after which the frequency is divided by a fixed number (Z) so that the frequency of the signal after multiplication and division becomes equal to the expected frequency of the measuring signal. Thereafter the control signal thus produced is mixed with the measuring signal, for determination of the phase difference between them, which is sampled in each of a succession of regular sampling intervals, and the change in phase difference through the successive sampling intervals is calculated for determining a correction term for the assumed distance.

Abstract: A warning system for rotary wing aircraft compares the accumulated altitude loss after take-off of the aircraft with its altitude above ground, and generates a warning if the altitude loss is excessive for the altitude above ground at which the aircraft is flying. The position of the landing gear, the speed of the aircraft and its altitude enable the system only during the take-off and missed approach phases of operation in order to minimize nuisance warnings during other phases. The relationship between radio altitude and altitude loss required to generate a warning is optimized for rotary wing aircaft such as helicopters.

Abstract: A dehumidifier element is produced by alternately laminating corrugated paper and flat liner paper, both papers being of low density and composed of inorganic fiber such as ceramic fiber, to form a honeycomb matrix having many small channels penetrating through opposite surfaces. The formed matrix is fired with hot air to remove organic substances contained in the sheets, or the sheets may be fired before the lamination. The matrix is impregnated with water glass after the laminating process, or the sheets are impregnated before the laminating process. In either case, the formed matrix is soaked in an aqueous solution of aluminum sulphate or magnesium sulphate to form a silicate hydrogel on the papers and in the apertures between fibers of the papers. The shaped matrix and the metal silicate hydrogel are washed and dried to obtain a dehumidifying element having physical strength. The metal sulphate solution is cooled to precipitate and remove sodium sulphate from the solution. Additional sulphate is added to the metal sulphate solution for repeating the manufacturing process for another dehumidifier element. The main constituent of the element is metal silicate aerogel deposited in the apertures between the fibers of the inorganic fiber paper and on the inorganic fiber paper, which acts as an adsorbent.
