Abstract: 221,389. Peuckert, F. H., and Wildt, E. Nov. 26, 1923. Fabrics having knitted and crocheted threads combined with a groundwork of woven threads; openwork fabrics. - A non-laddering fabric is formed from warp and weft threads d, e and knitting threads b, the threads d, e being interlaced by combined weaving and knitting devices. The threads b are traversed by guides c and operated on by sliding needles n to make a warp knitted fabric. The threads d pass through eyes in curved arms l mounted on bars k about a centre x to make a shed through which a shuttle f passes the thread e. To interlace the knitted and woven products, arched grippers q are mounted on elongated bosses g on a shaft and are rocked through 180‹. Each gripper is channelled and has a forked offset end h which passes under and grips a knitting thread b. The bosses g are grooved at i to accommodate the parts of the threads extending to the guides c. The shuttle passes through the arched parts of the grippers and through slots in their supports. The weft is beaten up by an horizontally moving reed s formed of I-shaped plates. If the arms l are brought over to the position shown in dotted lines, Fig. 1, a double fabric, interlaced with knitting, is produced. Pile and patterned fabrics and knitted fabric only partially interlaced with woven threads can be made.

Abstract: 856,343. Digital - to - analogue converters. LABORATORY FOR ELECTRONICS Inc. Dec. 19, 1956 [Dec. 19, 1955], No. 22834/60. Divided out of 856,342. Class 40 (1). A digital-to-analogue converter, Fig. 1, receiving on windings 82 parallel signals representing binary-coded decimal digits consists of four cores 81 for each digit, which correspond to the binary bits and have output windings 85 the number of turns of which is weighted (1, 2, 4 or 8) to correspond with the associated bit value, the output windings being connected in series so that the signal derived when the cores are reset is the analogue of the input decimal digit. As shown in Fig. 2, groups of four cores as in Fig. 1 may form a shift register, decimal digits being entered serially at terminals 31-34 and shifted along the register to the right. When the next-to-last stage contains a digit it initiates operation of a generator 35 which resets cores that were set. Each core has four weighted output windings 85, two producing positive signals and two producing negative signals. Corresponding terminals of all stages can be connected in series to derive an analogue signal representing the sum of all the decimal digits stored in the shift register. The signals produced by each stage may represent the value of a function, the function being stored in discrete sample values, in the shift register. The signal from each stage may be attenuated by a potential divider consisting of a resistance R and one of resistances R, R/2 or R/4 in a proportion corresponding to sample values of a second function and the sum of the attenuated signals indicates the correlation between the stored function and the second function.
