Filed: 2009-07-29
Abstract: A liquid crystal display is provided. In the liquid crystal display, a common line includes an edge common line (21) that is formed in a non-display area outside a display area of a liquid crystal display panel to receive a common voltage through a plurality of input units, a plurality of pixel common line patterns 23 that are formed along edges of each of subpixels to be electrically connected to one another, and a plurality of longitudinal common lines 22 that is electrically connected to the edge common line to apply the common voltage to the pixel common line patterns. Each of the pixel common line patterns has a mesh structure and is connected to common electrodes of the subpixels. Each of the longitudinal common lines is formed between two horizontally adjacent pixels in a direction parallel to the data lines D. This arrangement of the common line reduces the deviation in the common voltage across the display and as a result reduces crosstalk.

Patent GB-148617-A (GB)
Title: Improvements in or relating to the manufacture of dyes
IPC: C09B59/00
Filed: 1919-04-24
Abstract: Relates to the preparation of dyestuff from the oils and ammoniacal liquors which result from the low-temperature gasification of bituminous fuels, as described, for instance, in Specification 24426/13.  The ammonia liquor or the liquor obtained by washing the oils with water is first freed from ammonia and sulphuretted hydrogen, and after being made neutral, is treated with a ferrous salt such as ferrous sulphate.  A precipitate is obtained, which in an alkaline bath gives slate-coloured shades on wool, or by after-chroming yields brown shades.  The filtrate is made acid, sodium nitrite added, and then more ferrous salt is added to the neutral solution, whereby all the quinoneoxime present is thrown down as a precipitate, which dyes green, on iron-mordanted wool, similar to resorcinol green. The treatment of the liquors with nitrous acid may precede the addition of the ferrous salt.  Salts of the alkali metals or of ammonium may be added to aid the precipitation.

Abstract: 182,578. Bowen, R. April 8, 1921. Feeding; reciprocating-mould-table machines; rotary-mould-table machines; shaking and jigging machines; moulds; moulding fuel; tamping - machines. - Fuel is mixed with adhesive material and fed into a mould e bv means of a measuring device a<1> and a vibrating inclined surface b, the bottom of the mould receiving vertical oscillation and the upper part, after the mould is full, being closed by a pressure device which retains pressure on the material while the latter is being consolidated. In this. way horizontal laminations are produced in the fuel block. Vertical laminations may be produced by a series of vertical knives located in the mould during the filling operation and withdrawn before pressure is applied to the upper surface of the material. The moulds e which are arranged in pairs are adapted to slide beneath the vertical passage d. to enable the fuel to be ejected from one by rotation of the mould upon a rod h<1> ; by the same movement an empty mould passes into the filling position. The lower part of a mould is in the form of a loose plate e' which is oscillated by means of tappets f, a connecting plate f<1> and a series of rotating cams g capable of sliding on their shaft to regulate the motion of the tappets and so control the density of the fuel blocks. Above each mould is a top pressure device which may be in the form of a weight i<2> raised by a vertical rack j and allowed to fall somewhat slowly by gravity. The weight carries a lower plunger i and springs employed between the weights allow the plunger to respond to the action of the tappets without lifting the upper weight. In a modification a pair of tables revolving on vertical axes and geared together each carrying six moulds arranged in pairs equally spaced from each other. Whilst one pair of moulds is supplied with material the contents of another are subjected to nressure and the third receives plungers to eject the blooks. The tables are rotated through 120‹ between each set of operations.

Title: The separation of aminoacids from acid hydrolysates of proteins
Filed: 1939-04-04
Abstract: 527,320. Amino-acids. TOENNIES, G. April 4, 1939, No. 10546. Convention date, May 7, 1938. [Class 2 (iii)] In a process for separating amino-acids from acid hydrolysates of proteins, the hydrolizing acid is neutralized by an organic base. The resulting salt of one organic base is separated from the amino acids by means of an organic solvent in which the salt is soluble and the acids are insoluble. Before neutralizing the hydrolysate, it may be evaporated to a small volume, or the neutralized mixture may be evaporated to a small volume or to dryness before extracting with the organic solvent. Examples are given of the extraction of amino acids from hydrochloric acid hydrolysates of egg albumin, gelatin and casein, using amylamine as the neutralizing agent and chloroform and acetone as the solvents.

Shaft 15 passes with clearance through eccentric 27, and the latter is carried by a dovetail-section plate 40 slidably mounted on a block 44 fixed to shaft 15. Bellcrank lever 46 is pivoted at 48 to block 44 and one arm has a cylindrical end - 50 engaged with a slot 51 in plate 40, while the other arm is pivoted at 53 to an extension 54 of a sleeve 56 slidably mounted on shaft 15. A pin 60 projecting from block 44 is embraced by lugs 59 on sleeve 56 to prevent the latter from turning on shaft 15. Bell-crank lever 68 is pivoted at 69 to the machine frame, and one arm is provided with a roller 66 engaged between flanges 64, 65 on sleeve 56, while the other arm is pivoted at 72 to the lower end of a rod 73 slidable vertically in the machine frame.

Handle 79 is pivoted at 80 on the machine frame and is formed with a slot 83 engaged by a pivot stud 78 on rod 73. A flattened extension 82 of handle 79 is engagable by the elbow of an operator to move rod 73 downwards for shifting eccentric 27 from one position of extreme eccentricity to the other extreme position displaced 180 degrees therefrom. The movement of rod 73 is limited by the engagement of a pin 90 projecting therefrom, with one or the other of two nuts 92, 93. The latter are oppositely screw-threaded and are mounted for, simultaneous movement towards and away from each other on a screw-threaded rod 96 rotatable by means of a thumb-wheel 100. A graduated scale 107 indicates the position of handle 79 and thereby the stitch length. In a modification, Fig. 5, roller 66 bears against an end face 112 of a sleeve 110 interconnecting the bell-crank levers and a spring 113 biases said sleeve against said roller. Bell-crank lever 68 is nivoted at 114 to the lower end of a link 115, the latter being biased upwardly by the spring 105 and being pivoted at its upper end at 116 in a boss 118 formed on a handle 119 pivoted at 120 on the machine frame. The movement of handle 119 is limited by the engagement of boss 118 with one or the other of individually adjustable nuts 123, 124 mounted on a fixed, screw-threaded rod 125. A compression spring 127 arranged between nuts 123, 124 serves to retain the latter in adjusted position. Specification 724,419 is referred to.
