Title: Sheet feeding apparatus
IPC: B65H29/68
Filed: 1966-01-24
Abstract: 1,098,364. Delivering sheets. S.D. WARREN CO. Jan. 24, 1966 [Jan. 25, 1965], No. 3151/66. Heading B6H. A sheet feeding apparatus comprises a lowspeed conveyer Fig. 1A (28), a high-speed conveyer (14) located so as to project sheets over and on to the low speed conveyer (28) to form an overlapping stream, a roller (33) adjustable in a longitudinal direction defining a nip to trap the sheets and a set of tapes (36) extending above both the high and low speed conveyers with a bottom run (39) extending through the nip to provide a converging guide. A switching gate (12) is provided to deflect faulty sheets to a lower path (13) and allow good sheets to travel over the high speed conveyer. During this part of the feed a suction device 16 corrugates and longitudinally stiffens the sheet. Further stiffening is introduced by edge curling hemi-cylindrical guides (22). Leaving the high-speed conveyer (14), the sheets pass over a corona discharge bar 51 having a number of point electrodes within concentric outer electrodes (52). This ionizes the air to neutralize any electric charge on the paper at this point. The sheets are guided by the run (39) of the tapes (36) to the nip between the low-speed conveyer (28) and the roller 29 constructed of a surface layer of a dielectric e.g. silicone rubber to provide an intentional electric charge to the sheets sufficient to mark any random charges present and so achieve a uniformity in the pile in the layboy. The roller is longitudinally adjustable to accommodate different length sheets by a rack and pinion mechanism. When the sheets strike the nip between the roller (29) and the conveyer (28) a shock-wave straightens the edge curves introduced by the guides (22). The kinetic energy of the wave as it travels to the trailing edge, not only straightens the sheet but helps to slow it down.

Abstract: 5 9 9 , 9 2 2. Directive radio systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 9, 1945, No. 3369. Convention date, April 21, 1943. [Class 40 (v)] An antenna system whose direction of maximum radiation may be changed, consists of an array of three spaced radiator elements coupled to a main transmission line by branch transmission lines and has cyclically variable reactance means connected to the two side branch transmission lines. Dipoles 1 and 5 are fed by connecting lines 7, 9 and 19, 21 from junctions 11 and 23 respectively, quarterwavelength branch lines lead from these junctions to the end of the main feeder 33 ; the central aerial 3 is similarly connected to this point by connecting lines 13, 15 and a quarterwavelength branch line 27. Junctions 11 and 23 are also connected by lines 35 and 37 to the stationary plates 41 and 43 of capacitor 39 which is more fully described in Specification '599,383. The moving portion of this capacitor consists of a semicircular plate 45 mounted on coaxial line 42 which has an adjustable shorting plug 44; it may be rotated by motor 51. The lengths of lines 35 and 37 are adjusted so that minimum capacitance is reflected at junction 11 or 23 as a capacitive reactance and maximum capacitance as an inductive reactance, the values of these reactances being made equal by adjusting plug 44. Thus, as capacitor 39 is rotated, the energization of antenna 1 alternately leads and lags and antenna 5 lags and leads on central antenna 3, and alternate overlapping directive radiation patterns are produced.

Title: Improvements in or relating to stockings
IPC: D04B1/06
Filed: 1949-02-08
Abstract: 662,347. Knitting. SCOTT & WILLIAMS, Inc. Feb. 8, 1949 [March 1, 1948], No. 3464/49. Class 74 (ii). At least the sheer leg and instep portions of a stocking are knitted from a single nylon yarn with a relatively invisible and relatively runproof stitch repeat which extends walewise through twice as many courses as there are wales in its coursewise extent and which is of plain stitches, except that every wale contains one tuck stitch, one of which is' in every alternate course only of the repeat; the pattern is substantially indiscernable from more than three feet. Fig. 1 shows a repeat covering four wales and eight courses; but it might cover three wales and six courses, five wales and ten courses or six wales and twelve courses. The construction limits a downward run in a sinker wale to the length of the repeat, offers some resistance to upward runs along the needle wales, reduces the visibility of streaks and shadows and reduces sheen. The foot may be of this patterned fabric or plain. The pattern may be interrupted for a few (e.g. four) courses above the heel, to avoid straining and breakage of the tuck stitches where they are looped into the heavier heel yarn.

Title: Improvements in or relating to the synthesis of imidazolidone compounds
Filed: 1945-02-20
Abstract: Imidazolidones of the general formula <FORM:0598957/IV/1> in which R is an alkylene radical of not more than eight carbon atoms and R1 is hydrogen or COOR11, where R11 is hydrogen or an alkyl group of not more than eight carbon atoms, are prepared by the reduction of a keto compound of the general formula <FORM:0598957/IV/2> by catalytic hydrogenation under mild conditions until 3 molecular proportions of hydrogen have been taken up, and if desired saponifying the product when R1 is COOR11 and R11 is alkyl.  If desired the reduction may be effected in two steps by first reducing the keto group and subsequently reducing the double bond.  When the group CH2R.R1 is a caproic acid residue the product is desthiobiotin which is physiologically active.  The keto compound II may be prepared by decarboxylating a 4-methyl-5-imidazolone-(2)-carboxylic acid alkyl ester (the alkyl radical containing not more than eight carbon atoms) by treatment with a saponifying agent such as caustic soda, followed by reaction of the resulting 4-methylimidazolone with an acyl halide of the formula Halogen CO.R.R.1 under Friedel-Crafts condensation conditions.  In examples: (1) 4-methyl-5-imidazolone-(2)-carboxylic acid ethyl ester is decarboxylated by treatment with aqueous caustic soda giving 4-methylimidazolone, this is treated with adipic acid ethyl ester chloride in the presence of aluminium chloride to give 4-methyl-5-imidazolone-(2)-k-ketocaproic acid ethyl ester, which is hydrogenated using Adams platinum catalyst, either in one or two steps, then hydrolysed giving the final product 4-methyl-5-imidazolidone-(2)-caproic acid; (2) 4-methylimidazolone prepared as in (1) is treated with acetyl bromide and aluminium chloride to give the 5-acetyl derivative which is catalytically hydrogenated in one step to give 4-methyl-5-ethylimidazolidone-2; (3) 4-methyl-5-imidazolidone-(2)-butyric acid is prepared in an analogous manner.  The Specification as open to inspection under Sect. 91 comprises also the preparation of compounds of the general formula I where R11 is a cyclic alkylene group, and examples in which diacetyl - 4 - methylimidazolone - (2) is prepared by acetylating 4-methylimidazolone-(2); diacetyl - 4 - methyl - 5 - imidazolone - (2) - e  - ketocaproic acid ethyl ester by acetylating 4-methyl - 5 - imidazolone - (2) - e  - ketocaproic acid ethyl ester, and 4 - methyl - 5 - imidazoli dene-(2)-caproic acid methyl ester by treating 4-methyl-5-imidazolidone-(2)-caproic acid with diazomethane.  This subject-matter does not appear in the Specification as accepted.
