Patent GB-190301945-A (GB)
Title: Method of Preparing C-C-dialkyl-barbituric Acids from Mono-alkyl-malonic Esters.
Inventor: BOEHM FREDERICK
Filed: 1903-01-27
Granted: 1903-05-14
Abstract: 1945. Boehm, F., [Fischer, E.]. Jan. 27. CC-Dialkylbarbituric acids are produced by first preparing mouoalkylbarbituric acids by the action of a metallic alcoholate upon a mixture of a monoalkyl-malonic ester and urea, and then further alkylating these compounds by means of alkali and halogen alkyls. The first reaction is represented by the equation :- For example, diethylbarbituric acid is produced by heating ethylmalonic-diethyl ester with urea and a solution of sodium in alcohol in a closed vessel at 80‹-90‹ C. for six hours, dissolving the product in water, acidifying with hydrochloric acid, and then heating the ethyl-malonic acid thus obtained with ethyl iodide and caustic soda to 100‹ O. Methylethylbarbituric acid is obtained similarly, either by methylating ethylbarbituric acid prepared as above described, or by preparing metbylbarbituric acid and then etbylating this product.

Title: Manufacture of Red Lakes.
Filed: 1903-02-02
Granted: 1903-11-12
Abstract: 2503. Abel, C. D., [Akt.-Ges. f³r Anilin- Fabrikation]. Feb. 2. Pigments.-Relates to the production of rei lakes from dye-stuffs obtained by combining the diazo-compound of p-anisidine- or p-phenetidinesulphonic acid with #-naphthol. For this purpose, an alkali salt of one of the said dye-stuffs or alkali salts or a mixture of them is suspended in water, a solution of a metallic salt such as a salt of aluminium, barium, calcium, strontium, magnesium, zinc, or the oxide or hydroxide of one of these metals or a mixture of such compounds, is added either in the cold or while heating. Advantageously, the precipitates obtained in this way are mixed with a suitable substratum, such as calcium sulphate, aluminium hydroxide, or the like. The lakes are then filtered, dried, and pulverized. The lakes obtained from the phenetidine compound are rather more blueish than those from the other. The result is the same, if for the alkali salts of the dye-stuffs, the free acids are substituted.

Title: Improvements relating to Brakes for Railway and like Vehicles.
Inventor: CUMMINS MARK
Filed: 1903-05-21
Granted: 1904-03-03
Abstract: 11,592. Cummins, M. May 21. Brakes applied to the wheels by the movement of the operating-mechanism in either direction. As described, the movement is derived from that of a slipper brake, which may be electrically applied, but it may be produced by hand, by foot, or by pneumatic means. The brake-shoe is adjustably attached to a rod 5, Fig. 1, ending in a T-head with a channelled yoke 105 surrounding a double cam 107 on the transverse shaft 2, the rotation of which applies the brakes. An arm 13 fast on the shaft 2 and working in a slot in the slipper brake 11, actuates the shaft. In a modification, the cams actuate the brake-shoes by a thrust on the rods 5. In another modification, the rods 5, Fig. 5, are attached to slotted links 121 enclosing transverse beams 118, which are held freely in slotted brackets 119, and the beams 118 are forced apart by a lever 122 pivoted to one and bearing against the other, and actuated by a slipper brake, as before. In another modification shown in Fig. 6, the brake-shoes are carried by beams 18 hung on links 22 and carrying pivoted to them levers 24, which are also pivoted, at the top, to an adjustable tie-rod 25, and, at the bottom, connected by telescopic links 27 to the slipper brake, as shown. An intermediate knuckle 28 carries the end of a tierod 30 attached to the frame. On applying the slipper brake, the shortening telescopic link 27 turns the lever 24 above the upper tie-rod joint applying the brake on that side, and the thrust in the rod applies the other brake by pivoting round the joint of the knuckle 28. In a modification of this form, the tie-rod 25 is below the brake beams and the tie-rods 30 are replaced by thrustrods attached by a link held in position by pins. A modification for use with " maximum traction " trucks is shown in Figs. 10 and 11 ; a movement of the slipper brake to the right actuates the lever 41, against the pivot in a link 44 attached to a bracket 47 slotted to allow vertical motion of the slipper, and pulls the plates 51 to the right and, with them, the links 54, which pull the brake rod 5 and link 37 forward, and apply both brakes. If the slipper moves to the left, the lever 42 is fulcrumed in a slot 48 in the link 43, and pushes forwards the plate 50, applying the brakes, as before, a slot 52 in the plate allowing the necessary play.

Granted: 1904-09-22
Abstract: 20,673. M³llers, H., and Spindler, A. Sept. 25. Pile fabrics; jacquards. - Figured plush is woven with the pile warps divided into three parts d, e, f, instead of into two as usual. Two ground warps g, h are provided for each pile warp, the threads g being heavily, and threads h lightly, weighted. The ground warps are not drawn into the jacquard harness. The pile wires are inserted simultaneously with each weft thread that lies above the taut warps g. Three positions of the shed of the harness are necessary, but only two are necessary simultaneously, namely, with the pile warps in the top and bottom sheds in the odd picks, and in the top and middle sheds in the even or wire picks. The griffe of the jacquard is lifted at every pick by a crank on the main shaft, and a bottom lifting- board is raised at each wire pick by means of a cam on a second shaft. to raise the remainder of the pile warps into the middle shed. Drawn and cut effects may be produced by inserting drawing and cutting wires alternately at the even picks. Each drawing-wire and each cutting-wire is inserted under two of the three parts of the pile warps, so that only half the number of wires usually employed are required. The pile warps to be cut lie over the respective drawing-wires, in order that the condition of the pile may not be unfavourably affected. This method of weaving may also be employed in a two-part or other binding, and a three-part binding for the cut effect may be combined with a two-part binding for the drawn effect.

Title: Improvements in Can Seaming Machines.
Inventor: WHEATLEY WILLIAM HUMPHREY
Filed: 1904-04-30
Granted: 1905-04-29
Abstract: 9980. Wheatley, W. H., [Bliss Co., E. W.]. April 30. Metal, sheet, seaming.-Cans are seamed by apparatus such as that shown in Figs. 1 and 3. The can to be seamed is placed on a holder 26, which is moved upwards, to hold the can against a chuck 11, by depressing a treadle 27. The treadle is connected by a link 28 with a lever 29, connected by links 61 with a loose collar 60, in connection with the holder 26. the loose collar being normally pressed downwards by a spring interposed between the loose collar and a fixed collar 62. The lever 29 carries an arm 64, connected with a link 30, having a slot 65 at the end, in which moves a pin 66 of a bell-crank lever 31, connected with a rod 33, which is mounted at its upper end on a forked pivoted member 35, having two projections between which is situated the arm 78 of the lever by which the clutch 25 is actuated. The seamer-head 2 carries one or more seaming- members, of the kind described in Specification No. 9979; A.D. 1904. Each seaming-memtrer is mounted on a spindle 12,whichis rotated by a pinion 16; -actuated by a pinion 17, concentric with the seamer-head, the gearing being such that the pinion 16 is rotated only once for each twelve revolutions of the seamer-head. The pinion 17 is rotated from the shaft 3 through gearing 18, 19, 20, 21, the pinion 20, which is loose on its shaft, being put into gear with its shaft by the clutch 25. Thus, on operating the treadle, the can is brought into position, and the clutch 25 is operated to put the seaming - mechanism into gear. A catch, mounted on the pin 66, and having a slot in which a fixed pin 72 engages, and a hook 68, adapted to engage with a pin 69 on the link 30, holds the treadle and connected parts in position. The clutch 25, and connected parts, are also held in position by a hook 36, pivoted on the member 35, and adapted to engage with a ledge 80 on the bracket 75, the lower arm of the hook being actuated by a spring push 81. This hook also serves to actuate a lever 44, and thus a bell-crank lever 43, connected with a sleeve 42, to which is attached a rod 41. The rod 41 actuates a lever 40, and thus releases a stop 38, Fig. 3, by which a cam 37 on the pinion 16 was arrested. A pawl 45 prevents back movement of the pinion. When, at the end of a revolution, the stop again falls into the notch in the cam, the lever 44 releases the hook 36, and thus the parts automatically return to the inoperative positions.

Filed: 1904-05-25
Granted: 1905-01-05
Abstract: 11,895. Weber, J. A. May 25. Drawings to Specification. Embroidery machines ; cords, applying.-The invention consists of an arrangement whereby a design can be embroidered, or lace-made, in different colours without having continually to change the reels of cotton, yarn, silk, or the like, or to re-thread the needles. As many needles as there are colours in the design are arranged side by side in the machine, and are threaded from reels of variously coloured silk &c. which are arranged in rows on a spool plate. The work is secured in a pantograph frame which is moved so that its point rests over a pattern plate on which are arranged as many patterns of the design as there are colours in it. The pantograph point is then traced over those portions of one of the patterns which are of the same colour, so that the needle threaded with silk &c. of that colour correspondingly embroiders the work. Afterwards, the pantograph point is moved over to the next pattern, and those portions of the design in the second colour are traced out to embroider the work in the second colour, and so on. The end of the silk &c. of any one colour is not cut off, but is carried directly through the other part of the design and embroidered over by the next colour. The work is then edged with rows of cording which is sewn over by a cross overstitch, such as a herring-bone stitch, so that the cording remains visible.
