Title: Aromatic dicarboxylic esters useful as liquid crystal substances
IPC: C09K19/20
Filed: 1978-01-05
Abstract: Tricyclic cyclohexanecarboxylic acids or cyclohexyl esters of the formula <IMAGE>  in which     R<1> = CnH2n+1, where n = 1 to 9, R<2> = CnH2n+1-, CnH2n+1O-, CnH2n+1COO-, CnH2n+1 OCOO-, where n = 1 to 9, -CN, -Cl, -Br or -C2H4CN,   X = <IMAGE>,   R<3> = H, -CH3, -C2H5, -Cl, -Br, -CN or -CH2CN,   R<4> = CnH2n+1- or CnH2n+1O-, where n = 0 to 9.   As liquid-crystalline substances and/or as essential constituents of mixtures, these compounds have high chemical and thermal stability, no inherent colour, relatively high clearing points at the same time as sufficiently low melting points, and low viscosity values. The liquid crystals can be used both for the production of opto-electronic components and as an orienting (aligning) medium in spectroscopy and in gas chromatography.

Title: Means for feeding shuttles to weaving looms incorporating an automatic shuttle changing device
IPC: D03D45/34
Filed: 1949-01-06
Abstract: 669,326. Automatic shuttle-changing mechanism for looms. BUTIN, E. A. Jan. 6, 1949 [Feb. 19, 1948], No. 409/49. Class 142(iii) Shuttles for a loom, which may have a dropbox motion, are stored in upright holders and the lowermost shuttle is carried through 90 degrees by a cradle to the shuttle box upon indication of weft exhaustion. The ends of the shuttles are held in holders 11 by blocks 22. Upon weft exhaustion, a shaft 50 commences to rotate and a cam 55 thereon operates a cable 20 which causes a projection 19 to move a member 13a. Member 13a rotates rods 8a at the back of the holders through links 10a, 12a. Rotation of rods 8a moves blades 28, Fig. 9, and allows the lowest shuttle to fall on to a support 35 where arms 32, 33 grip the shuttle and, on rotation of a shaft 31 controlled by a cam 49 on shaft 50, move the shuttle through 90 degrees and place it in the shuttle box. The projection 19 is rocked continuously by shaft 16 on which it is mounted so as to be in line with lever 13a or 13b according to which shuttle box is in operation at any given instant. When a shuttle has fallen from a holder the lower block 22 turns under the action of a soring and allows the shuttle above to slide down a slot 24, which engages the shuttle tip 26 into the lowest position. Similarly, each shuttle then moves down one position. In a modification, the arms 33 may be replaced by projections on the arms 32 and arms 32 connected to, and move with, the projection 19 so as always to be beneath the holder corresponding to the shuttle in operation. The spent shuttle is ejected into an auxiliary box 60. Specification 644,363 is referred to.

Title: Error correction method for the transfer of blocks of data bits,a device for performing such a method,a decoder for use with such a method,and a device comprising such a decoder
Inventor: SCHOUHAMER IMMINK KORNELIS ANT
IPC: G11B5/09
Filed: 1991-10-24
Abstract: For an error correction method for the transfer of word-wise arranged data, two word correction codes are successively used, each code acting on a group of words while therebetween an interleaving step is performed. The actual transfer takes place by means of channel words for which purpose there are provided a modulator and a demodulator. Invalid channel words are provided with an invalidity bit in the demodulator. During the (possibly correcting) reproduction of the data words, the invalidity bits can be used in one of the two error corrections in various ways. When too many words of a group of code words are invalid, all words of the relevant group are invalidated. If a word comprising an invalidity bit is not corrected during correction by means of a syndrome variable, all words of the relevant group are invalidated. If the number of invalidity bits lies within given limits, they act as error locators so that the code is capable of correcting a larger number of words.
