Title: Improvements connected with Apparatus for Bottling Aerated Liquids.
Inventor: WICKHAM DENNIS
Filed: 1901-09-20
Granted: 1902-09-04
Abstract: 18,839. Wickham, D. Sept. 20. Bottling.-Relates to machines for bottling beer or other aÙrated liquids. To prevent the delivery chamber or cylinder H from being flooded with liquid, in case the gas pressure in the cylinder is reduced by the bursting or breakage of a bottle, the cylinder is provided with a partition C, having a seat D for the valve E, which is closed by the float F when the liquid rises above a certain level. The float also relieves excessive gas pressure within the cylinder, by opening the snift-valve I. The partition C may be dispensed with, and a valve arranged in the lower part of the cylinder to control the admission of the liquid. The top and bottom of the cylinder are connected by gas and liquid pipes respectively to the tap K, Fig. 2, of the filling-head. The gas is first admitted to the bottle, and then the liquid is supplied, the liquid as it enters the bottle forcing the gas therein back into the cylinder H. The bottle is supported on the spring-controlled rest N, which is mounted in a guide-tube P provided with a number of trunnions Q adapted to bear on the end of the rocking lever R, the trunnions Q enabling the rest to be adjusted for bottles of different lengths. The lever R is actuated through the rod S by the cam U on the hand-lever V, to raise the bottle to the filling-head. A roller or projection X on the lever V engages the fork Y on the tap K, to open the tap, and the fork moves the arm Z of the pivoted guard Z<1>, to close the guard around the bottle. The machine may be constructed to fill a number of bottles simultaneously.

Patent GB-190207836-A (GB)
Title: Improvements in Processes for Colouring Building Materials such as Lime, Mortar, Bricks and Artificial Stone
Inventor: SCHULTHESS WALTER
Filed: 1902-04-03
Granted: 1903-06-03
Abstract: 7836. Schulthess, W. April 3. Bricks, building-blocks, &c.-The mortar or composition from which artificial stone blocks are moulded may be coloured by the addition of a lake formed by precipitating a neutral or alkaline solution of an organic colouring - substance with the hydroxide of an earth alkali or metal. A moulded block of natural or artificial stone may be first impregnated with a solution of the alkali or metallic salt and then treated with an alkaline solution of the organic colouring-substance. If colouring-materials are used which are precipitated only at a high temperature, the two solutions may be mixed, the reaction taking place during the subsequent steaming For this reaction the most suitable colouring matters are the "Bordeaux' colours, salts of manganese, zinc, lead or iron being used with them. The lime used for making the mortar may be separately coloured by adding to the water, used for dissolving it, a solution of the organic colouring-substance, a lake being formed by reaction with the lime. An already-precipitated lake may also be added to the lime. Stones or masonry may be impregnated with a solution of a substance, such as indigogen, from which a colouring-matter is precipitated by oxidation. Metallic solutions, such as ferrous chloride, may also be employed, a coloured precipitate being thrown down in the pores of the stone when an alkaline carbonate or hydroxide solution is applied to it. The colouring may also be produced by employing solutions of metallic salts which can be decomposed by heat so as to leave an insoluble oxide, carbonate, &c. A solution of blueish-green chromic hydroxide, in sulphurous acid, for example, gives a green precipitate when heated. The colouring processes may be applied to building-materials containing lime, and to moulded articles, bricks, &c.
Patent GB-190209126-A (GB)
Title: Manufacture of Yellow and Orange-yellow and Red Dyestuffs of the Acridinium Series.
Inventor: IMRAY OLIVER
Filed: 1902-04-19
Granted: 1903-02-19
Abstract: 9126. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. April 19. Dyes, artificial.-Yellow to orange-yellow and red dye-stuffs bf the acridinium series are produced by heating in dilute hydrochloric - acid solution, with methyl or ethyl alcohol at a high temperature, the leuco compounds obtained by heating tetramidoditolylmethane or dialkyl or tetraalkyl - tetramidoditolylmethane with dilute hydrochloric acid, or the said methane bases themselves. An example is given, in which leuco acridine-yellow is formed from m-toluylenediamine, hydrochloric acid, and formaldehyde, and the cold solution thus obtained is directly heated with methylalcohol at 160‹-170‹ C. for two hours. The clear yellow solution is oxidized by ferric chloride, and the dye is separated by common salt and zinc chloride. After purification, it is obtained as a crystalline orange-red powder. The shade is redder when a larger proportion of methylalcohol is used, and when ethyl alcohol is employed the product dyes pure yellow. The alcohol may be added during the process of condensation, that is, to the solution of the tetra-amidated methane base. In place of leuco acridine-yellow, or the materials which yield it, the following substances may be used :-monoalkyl-m-toluylenediamine, mamidodialkylaniline, or o-diamido-derivatives of p-tetra-alkyldiamidodiphenylmethane or of pdialkyldiamidoditolylmethane. It is characteristic of the dyes that their free bases are not precipitated from solutions of their hydrochlorides when heated with ammonia, but only by caustic-soda lye.

Patent GB-190213663-A (GB)
Title: Improvements in Differential Thermometers Adapted for use as Maximum Electric Demand Indicators.
Inventor: FRICKER GUY CAREY
Filed: 1902-06-16
Granted: 1903-05-28
Abstract: 13,663. Fricker, G. C. June 16. Thermometers.-Relates to differential thermometers adapted for use as maximum electric demand indicators, and described as so applied, though claimed also independently. The thermometer is so constructed that, when one bulb is heated to a greater degree than the other, air or gas will be transferred to the cooler bulb past a bead of mercury, or an equivalent liquid valve, which will, upon a subsequent equalization of temperature, be forced back along the connecting-stem between the bulbs and serve as an index of the maximum difference of temperature- For indicating maximum electric demand, one bulb is heated by a coil through which the current passes. In Fig. 2, 1 and 2 represent the two bulbs c<1> the thermometer, which may be readily removed from the instrument, and 4 shows a bead of mercury which, before the insertion of the thermometer, is shaken down into the bulb 1, and which afterwards rests at the neck of the bulb as shown. A coil 5 embraces the bulb 2, and is connected up to receive the current to be indicated. The bulb 2 is thus heated to an extent dependent on the strength of the current, and some of the air, hydrogen, or other gas or vapour therein is driven into the upper bulb. When the current ceases to flow, or on removing the thermometer from the casing, the temperature of the two bulbs becomes again equal, and the pressure in the lower bulb diminishes. The bead 4 is therefore driven down the stem to an extent depending on the maximum difference of temperature produced. The ends of the coil 5 are preferably attached to spring arms 6 and 7, which cause the coil to grip the bulb, and which, when the bulb is withdrawn, come into contact with each other, and short-circuit the coil. The casing has a front cover, hinged below, a part only of which is shown at 15 in its open position. The thermometer rests below on a plate 12, and is pressed down by a light spring at 11. In place of an enveloping coil, a conductor sealed into the bulb of the thermometer may be employed. Any suitable liquid may be used for the valve and indicator 4, and the thermometer may be charged with the vapour of the liquid used ; for example, alcohol. A mercury bead may also be used with alcohol vapour or the like, and a mixture of gases and vapours may be employed. According to the Provisional Specification, the thermometer may be made with a U-shaped or bent stem ; it may also be symmetrical, so that the resetting may be facilitated by reversing it in the casing, in which case either bulb may be used as the hot bulb.

Telegraphs.-Relates to arrangements in a Morse receiver for causing the paper to feed automatically during the reception of a message, and also to means for throwing out the automatic devices. The armature P is provided with a lever T arranged to raise the detent C from the toothed wheel R on the commencement of a signal. The wheel R has a balance weight L, which can fall against a stop a, and a detent lever A which normally engages with a stop B on the governor worm shaft v<1>. The stop-disc is held frictionally on the shaft by a plate spring r. On the completion of a message, the detent C engages with the wheel R, and a cam-wheel D re-sets the stop-lever A by rotating the wheel R. The friction spring r allows the cam-tooth d to clear the wheel R before coming to rest. The wheel R is mounted on a plate P<1>, pivoted at X, and is provided with a thumb-piece B<o>, so that, on rotation to the left, the automatic arrangements are cut out.

Abstract: 21,256. Harper, R., and Giroud, P. G. Sept. 30. Printing. - Relates to apparatus for determining the best time of exposure in printing, which is also provided with mechanism for automatically cutting off the light at the predetermined time. The negative and printing-paper are placed in a frame 4. Mounted on the frame is a sliding screen which is moved, say every five seconds, in steps regulated by the corrugated strip 6, in front of the printing-frame. By means of a scale on the bottom of the printing-frame, the correct exposure is read off after examining the print. To cut off the gas at the prescribed time, an arm 47 is set to the time on a dial 46 which is rotated by clockwork once per minute. This arm, at the end of the time interval, releases a detent 45, which permits the gas cock 39 to be closed by a spring. If a lamp is used, mechanism for dropping the screen similar to that for cutting off the gas, is used.

Granted: 1904-02-25
Abstract: 8866. Schill, C. H., and Lane, H. April 20. Gas cocks; plug cocks.-A cock for incandescent gas burners is so arranged that, with one movement of the cock, the gas is turned on fully before the air is admitted and also the air supply is completely shut off before the gas is shut off. The cock d, Fig. 2, consists of a hollow plug 1 in a socket 2 flanged at the top where it is screwed into the burner tube a. The flange has two air inlets 3, Fig. 4, controlled by a flat valve 4 which fits on a square on the plug 1 and is secured by a nut 7 screwed on the end of the plug. The plug has an opening 8, Fig. 2, to admit gas from the supply pipe c. After the gas passage is fully open, further rotation of the plug in the same direction opens the air inlet, and the gas may be quietly ignited. When the plug is turned the other way, the air supply is shut off first and lighting-back is prevented. A stop 9 on the plug works in a recess in the socket 2 and limits the movements of the plug. In the case of air being the injecting- medium instead of the gas, the cock is arranged so that the air is first turned on and the gas follows, the gas being turned off first on extinguishing.
