Abstract: A b s t r a c t The invention relates to a coupling element for the coupling together of two building elements, of which one exhibits a tunnel-shaped space, into which the coupling element in mounted condition is inserted and to which it is locked. The coupling element moreover exhibits a projecting head, which can be coupled together with the other building element. The coupling element comprises two parts, viz. one piston-like lock bolt provided with said head and a shell case, in which said part can be axially displaced, the outer contour of the shell case following the inner form of the tunnel-shaped space. In the shell case (2) there is a laterally displaceable insert (1), which exhibits a lateral socket (17), which in a sideways displaced position cooperates with a hole (18) of the wall of the tunnel-shaped space by engaging said hole. Inside of the insert (1) the shell case (2) supports a transversely directed springing tongue (15), which is arranged in such a manner that for one thing it tends to displace the lock bolt (3) in outwards direction and for another thing to displace the insert (1) in sideways direction, before the lock bolt has been inserted into the shell case.

Abstract: ABSTRACT     Oxygen compounds are removed, e.g., by solvent extraction, from a shale oil prior to its hydrogenation.  As a result, the amount of hydrogen consumed during subsequent hydrogenation to achieve a given level of nitrogen for the shale oil is less than that which would occur if the oxygen compounds were not removed from the shale oil.  Removal of the nitrogen is necessary to avoid adverse effects on subsequent shale oil processing steps such as catalytic cracking.

Abstract: ABSTRACT     A self-sealing washer for use between two surfaces to be bolted or screwed tightly together which requires sealing at the surfaces to prevent the leakage of fluid, and which washer can be reused.  The structure comprises a rigid spacer consisting of two rigid concentric rings between which is an annular gap containing a sealing ring of flexible but incompressible material such as an elastomer, a thermoplastic or a soft metal.  One of the faces of the gaps is tapered in the axial direction of the washer and the inner and outer spacer rings are offset in the uncompressed state of the washer so that when the washer is compressed to bring the spacer rings to the condition where they are mutually aligned the compression face acts to squeeze the spacer ring material to effect sealing action against the surfaces between which the washer is compressed.  The theoretical reduction in the volume of the gap between the uncompressed and the compressed state of the washer is in the range of from 5% to 30%.

Abstract: SPELLING ERROR DETECTOR APPARATUS AND METHODS            ABSTRACT OF DISCLOSURE         A spelling error detector apparatus employs a memory which stores alphabetical words as those existing in the English language in three major memory sections which constitutes a most frequently used word list (MFU), a master word list (MWL) and a personal word list (PWL).  Each word is uniquely coded and stored as a 24 bit binary number.  The system then retrieves words which are stored or entered into a processor memory and which words are indicative of a document to be printed.  Each word emanating from the processor memory is converted into the same code as the stored words and then a search is made to determine whether the processor word compares with a word as stored.  If a favorable comparison is had, it is assumed that the spelling of the processor word is correct.  If an unfavorable comparison is had, it is assumed that the spelling is incorrect and the mis-spelled word is stored in a separate memory which can be accessed by the operator in order to make the necessary corrections.  Simi-larly each word which is correctly spelled is also stored in a memory which has the capacity to store a plurality of the last words checked by the system.  Based on the system considerations the coding of the words assures a very low collision rate and hence the system is extremely reliable in detecting misspelled words according to the disclosed techniques.
