Filed: 1988-04-05
Abstract: The invention relates to a centrifugal sifter having a housing provided with inlets for sifting material and sifting air or a sifting material/sifting air inlet and outlets for sifting air/fine-grade material mixture and coarse-grade material, in which housing at least one rotor formed essentially by a ring of blades is mounted. 
<??>The invention is based on the object of providing a centrifugal sifter of this kind which does not require a special seal between the shaft and housing and can be constructed with a relatively short shaft. 
<??>This object is achieved in that the rotor (2) is mounted in the housing (1) by means of at least one bearing (14) which can be rinsed with a fluid, which bearing serves at the same time as a seal between the rotor or rotor shaft (15) and housing (1; 1a).

Abstract: When pipe systems for said purposes consist of enamelled pipe parts, the practically enamel-free cut edges at the pipe ends and lateral openings of the pipe system form points which are liable to corrosion, which it is important to protect, in order to prevent premature damage to the pipe system by the aggressive components of the flue gases or of the condensate. According to the invention, protection of these cut edges 26, 27 takes place in that they are conducted outwards out of the waste gas-bearing clear cross-section of the pipe parts 15, 16, by designing flanges 28, 29 on the pipe ends or pipe collars on the inspection and connection openings, and embedded in an acid-resistant sealing compound 34. This sealing compound 34 is contained in a cavity of a connecting and clamping ring 30 for the pipe parts 15, 16 or on each sleeve-shaped extension piece for the pipe collars. The flanges 28, 29 and also the pipe collars are rounded off in such a manner that there are no edges which might lead to corrosion of the enamel. <IMAGE>

Abstract: In the production of organomineral products employed, in particular, in processes for strengthening rocks, it is a disadvantage that in general foams are used which have inadequate strength and that, in addition, the hard polymer segments responsible for the strength of the organomineral products do not contribute toward the adhesion of the organomineral products if these are employed in situ for strengthening rocks. By reacting organic polyisocyanates with epoxy resins in the presence of aqueous alkali metal silicate solutions, where the reactants are employed in a mixing ratio in accordance with the equation  x(Me2O) + y( <IMAGE> ) + (2x + y)(NCO) -> products expansion of the reaction mixture is prevented and an organic polymer structure containing oxazolidinone ring structures and carrying adhesion-improving OH groups is formed.

Abstract: Modified proteins for carrying hapten are provided. These carriers are prepared by blocking the amino groups of the original protein and then introducing amino groups into the carboxyl groups of the original protein. The blocking groups may be eliminated at the later stage to regenerate the amino groups of the original protein. The modified protein or polypeptide carrier have the three-dimensional structures different from the original proteins so that they are used in immunoassay while carrying low molecular weight haptens without the fear of forming antibodies for the original proteins. The modified protein carrier may also be used in the passive agglutination immunoassay without the need of absorbing the anti-hapten antibodies by the hapten-carrying carriers.

Abstract: A method and apparatus for determining structural properties of corrugated paperboard in which a sample 21 is held between two axially aligned jaws 13 and 14. The sample is subjected to a twisting force by rotation of one of the jaws and the force and angle of deflection are measured. This gives a relative determination of the boards structural property and is used to assess damage to the corrugated medium during corrugation and subsequent processing steps such as printing. The determination of shear stiffness in the machine direction is a more reliable measure of board damage than board thickness.

Abstract: A system is described for encoding/decoding an 8-bit binary code to/from a 4/11 channel code. In principle, the 8-bit binary code is encoded to a 11-bit channel code by adding a 3-bit extension code as a parity code which regulate the number of "1"s in the channel code at four. When the 8-bit binary code cannot be encoded by this rule, it is converted to a temporary 8-bit code by a table encoder and then added a 3-bit extension code. The 4/11 channel code is decoded referring to the 3-bit extension code, which indicates the encoding rule by which the 4/11 channel code has been generated. When the 4/11 channel code is detected to have been encoded by the bits-adding rule, an original 8-bit binary code is derived from the 4/11 code by removing the 3-bit extension code. When the 4/11 channel code has been encoded by the table-encoding rule, it is decoded by a table decoder.

Abstract: A method and apparatus for keying digital colour TV signals to avoid "stairstepping" of pixels at the edges of the key whilst retaining a hard switch between the keyed scenes. This is achieved by comparing successive digital keying signals with a desired digital clip level. In the event that the clip level occurs between two successive digital signals an interpolation of the clip level between these is created fractionally. A digital representation of this fraction is then included in the keying signal so that keying is accomplished on a sub-pixel basis without actually increasing the frequency of sampling.

The translated system software operates on the image of the source computer address space in the target computer exactly as it did in the source computer. The semantics of the source computer system software are thus preserved identically. In addition, a virtual hardware environment is provided in the target computer to manage events and to deal with differences in the address space layouts between the source and target computers.

Abstract: A butterfly valve of the type in which a valve stem is prevented from slide engagement with a valve seat is disclosed which assures more complete shaft sealing without causing any inconvenience to the controllability of the valve body and valve stem and can thus advantageously prevent fluid from leaking outwardly of a valve casing. A drive shaft rotatable and reciprocatable in longitudunal directions of the valve stem is connected to an outer end of the valve stem. The valve casing extends so as to cover the drive shaft, and a packing member is disposed between the valve casing and the drive shaft to provide a shaft seal for the drive shaft. The rotation of and reciprocating movement of the drive shaft connected to the butterfly valve are performed by a simple drive mechanism. That is, the rotation of and the reciprocarion of the drive shaft are accomplished only through rotation of a control shaft.
