Abstract: ABSTRACT       Liquid and gas proof container of a non-shape permanent type and comprising a gas sealed container sleeve  and in which the sealing at least at one end is formed as a bellow bottom and above said bellow bottom as a protection lid. The bellow bottom is connected to the inner surface of the container sleeve over a gas proof joint whereas the protection lid is connected point by point or discontinuously so that the air volume existing between the bellow bottom and the protection lid is communicating with the ambient atmosphere. An apparatus for executing the method comprises a carrier (9) for the container sleeve (1) and a plunge (11) for shaping and pressing a bellow bottom blank (27) and a protection lid blank into the carrier (9) and the container sleeve  whereby a rim of the bellow bottom blank and the protecting lid blank respectively is fold up  and in which the plunge comprises a lower plunge part (17) and an upper plunge part (18) which are axially movable in relation to each other and between said movable parts and expandable rubber rings (19) which upon compression of the two movable plunge parts are pressed radially outwards in direction to a welding ring (10) mounted in the carrier (9) for weld joining of the rims of the bellow bottom and the lid respectively to the inner surface of the container sleeve. The bottom of the lower plunge part (17) has a bulging (21) the shape of which defines the shape and size of the bellow bottom. The welding of the bellow bottom is made by means of an expandable rubber ring (19) as located or, level with the welding ring (10) in the carrier (9)  whereas the welding of the protection lid is made by means of some part of the bulging sides and with the rim of the protection lid on level with the welding ring (10).

Abstract: MODULAR FLOOR PANEL SYSTEM                Abstract of the Disclosure A floor panel system for use in grain storage and drying bins is disclosed which uses modular perforated floor panels each of which is hemmed across the width of the panel at predetermined points along its length so that panels of various lengths can be provided readily by breaking standard panels along any appropriate selected hem.  The hems also reinforce the panels.  Each modular floor panel may have a complete hem at one end and a half hem or flange at the other end such that the panels can be readily aligned and interlocked end-to-end by inserting the half hem or flange of one panel into the full hem of a succeeding panel.  A transverse clip may be used to hold together two abutted modular floor panels end-to-end and for reinforcing purposes where high floor loads are contemplated.  Adjacent panels are abutted together along the sides and are held together by fitting the side lips into rails or support beams.  These rails in turn are resiliently gripped in notches cut into the top edges of the side walls of V-shaped posts. The beam can be fit into these posts and resiliently held by the legs of the post, as when the post is squeezed and then released.

Abstract: Abstract Temperature Compensated Optical Pressure Sensor An integrated optical pressure transducer having a diaphragm fabricated from a low-loss glass is positioned at the location where pressure changes are to be measured.  An optical waveguide loop formed on one surface of the diaphragm acts as a ring cavity in which the difference between the resonating frequencies varies with pressure but not with temperature.  Light energy is coupled into the waveguide loop from an optical source through a tangentially located input waveguide. An output waveguide, also tangentially located, couples light energy from the waveguide loop to a broadband detector so that the changes in frequency spectrum of the resonating frequencies within the waveguide loop can be monitored.

Abstract: ABSTRACT            Sonic and ultrasonic distance measuring device The sonic or ultrasonic distance measuring device used for example to measure the filling level in a container comprises an electroacoustic transducer which operates alternately as transmission transducer for the transmiss-ion of sonic or ultrasonic pulses and as reception transducer for the reception of the reflected echo pulses.          Connected to the transducer is a signal processing circuit which includes an amplifier with controllable gain and a threshold value discriminator.  A gain control circuit controls the gain of the amplifier during a predetermined period after the start of each transmission pulse in accordance with a stored function which is fixed in accordance with the dying-down behaviour of the trans-ducer so that the electrical reception signals originating from the dying-down of the transducer after amplification are smaller than the threshold value of the threshold value discriminator but are as close as possible to said threshold value.  As a result the evaluation of echo pulses which occur during the dying-down of the trans-ducer is possible.

Abstract: SYSTEM FOR COMPRESSING AIRCRAFT FLIGHT DATA UTILIZING A MULTILEVEL TIME FORMAT                 Abstract A data processing system for use in a solid state flight data recorder wherein a plurality of aircraft parameter signals are processed and stored in electronic memory for later retrieval. The processor identifies those aircraft parameter data signals to be stored and for each such datum signal produces a signal triplet comprised of a parameter label signal, a time tag signal representative of the time interval from a reference time within which the data signal was produced, and the datum signal. A frame of the data bit stream produced by the data processor for storage in the memory includes an initial reference time signal followed at fixed intervals by time tick signals. Each signal triplet is positioned in the data bit stream following that initial reference time signal or time tick signal to which its time tag signal is referenced. By so tiering the data time formatting a substantial compression of data is realized thereby reducing memory size requirements.

Dry chitosan, when dissolved in dilute acid and neutral-ized, is applied directly to cereal crop seed with only minor modification to seed treating machinery and methods.  In addition to a clear benefit in cereal crop yield, the chitosan treated seed can be planted early to reduce erosion and it can be planted in regions having soil infested with root rotting organisms and not suffer extensive lodging that would prevent seed recovery by commercial harvesters.

Abstract: METHOD OF REMOVING DEPOSITS FROM THE INSIDE WALLS OF A PIPELINE AND APPLYING PROTECTIVE COATINGS THERETO                         Abstract A method of removing deposits from the inside surface of a pipeline and applying a protective coating thereto includes cleaning the pipeline inside surface and treating this surface with a solution of corrosion inhibitor to form a coating on the pipeline inside surface followed by a subsequent treatment with a solution of corrosion inhi-bitor to maintain the strength of the coating thus applied. According to the invention, the proposed method offers cle-aning the inside surface by jets of liquid which produce a pressure differential between the core of deposits and their surface to separate the deposits from the pipeline walls, while simultaneously impregnating the remaining layer of deposits with a solution of corrosion inhibitor carried by such liquid, or treating the layer with a cor-rosion-promoting agent and subsequently impregnating the layer with a solution of corrosion inhibitor to form a coat-ing.

Abstract: Abstract NARROW BANDPASS DIELECTRIC RESONATOR FILTER A extremely  narrow-band  bandpass  electromagnetic filter  comprises  a waveguide  (1)  dimensioned  below cutoff and having two or more active section (30) each containing a dielectric resonator  (6).   The number of resonators  (6)  corresponds to the number of poles of filtering.   The  physical  dimensions  of  the  waveguide (1)  can advantageously be further reduced by means of passive coupling means  (40),  where  the waveguide  (1) cross-section is smaller  than  in  the active sections (30).   Each  passive  coupling  means  (40)  inductively couples   adjacent   active   section    (30).    Mode suppression  rods  (10)  electrically  connect  opposing waveguide  walls  (2, 3)  midway  between  each  pair  of adjacent   dielectric   resonators    (6).     Preferred embodiments  are  illustrated,  in which  the  resonators (6)  are  transversely  oriented  within  the  waveguide (1).    Electromagnetic   energy   travels   within the waveguide  (1)  in  a  single  TE10  evanescent  mode (TE01.delta. within the resonators  (6)).   Dielectric tuning means  (9)  are  generally  aligned  along  the principal axis of each resonator (6).  A number of such filters, exhibiting  extremely  narrow  bandwidth,  low  insertion loss, and high Q, have been successfully built.
