Abstract: 24,278. Fiddian, W. Nov. 6. Sewage and foul w a t e r s, treating; filtering. - An apparatus for evenly distributing liquid sewage or sewage effluent upon the surface of an annular fitter bed consists of a radiating arm A, turning upon a fixed axis a, and having mounted between its two branches F, F<1> a water-wheel E, to which sewage is supplied through one of the branches F over a number of weirs k. The water-wheel shaft has fixed to its outer end a wheel G, running on a circular track H, so that the rotation of the waterwheel causes the arm to travel round the bed at a speed depending upon the flow of sewage. A loose wheel J, mounted on the inner end of the shaft, runs on a concentric track K. The supply of sewage to the filter bed is increased as the distance from the axis increases. For this purpose, the water-wheel may be divided up by transverse partitions j into compartments, which decrease in width outwards ; or the weirs k may increase in width outwards. Two or more distributing-arms, each carrying its own water-wheel, may be arranged so as to turn on a common axis, and thus supply two concentric annular filter beds.

Title: Improvements in the Manufacture of Halogen Derivatives of Oxyanthraquinones.
Filed: 1903-04-14
Granted: 1904-04-14
Abstract: 8503. Iljinskij, M., and Wedekind & Co., R. April 14. Dyes, artificial; b-oxyanthraquinones.-Halogen compounds of m-mono-oxyanthraquinone, anthraflavic acid, isoanthraflavic acid, alizarin, flavopurpurin, and isopurpurin, &c. are obtained by treating these bodies in aqueous suspension. The bromo compound is obtained in the cold, and the chloro compound under heat, assisted by the addition of neutral salts or of sulphuric acid. The new bodies are permanent, may be re-crystallized without decomposition, can be dissolved in dilute alkali without decomposition, and can be precipitated from the latter solution by acids. When sublimed, they decompose, the halogen escaping. When heated with fuming sulphuric acid, sulphonic acids form. When derived from colouring oxyanthraquinones, they produce directly colouring-matters, and when from either colouring or non-colouring oxyanthraquinones, they can be used as raw materials for making new colouring- matters. The following examples are given :-(1) m-mono-oxyanthraquinone or antbraflavic acid is suspended in water, and sulphuric acid and bromine added in the cold. The light-yellow dibromo compound formed is filtered off, washed, and dried. (2) Anthraflavic acid or flavo-purpurin is suspended in water and slightly acidulated with sulphuric acid. Bromine is then added in the cold while stirring. Tribromo-anthraflavic acid is produced, and is filtered off &c. When flavo-purpurin is used, a small quantity of sodium sulphite is added before filtering &c. (3) Alizarin or flavo-purpurin is suspended in water, brought to ebullition, and a mixture of potassium chlorate and crude hydrochloric acid slowly added. The light yellow precipitate formed is filtered &c. as usual. When flavo-purpurin is used, a solution of the compound obtained in dilute alkali has a somewhat lighter colour than flavopurpurin. Mordanted fabrics, when dyed therewith, acquire more yellowish shades. (4) Anthraflavic acid is suspended in water, sulphuric acid is added, and the whole is heated to about 120‹ C. and maintained at this temperature, while a solution of potassium chlorate and common salt is allowed to enter slowly while stirring. The product obtained is cooled, sodium bisulphite is added, and the resultant fine yellow dichloroanthraflavic acid is filtered off &c.

Title: Improvements in and relating to Coin Freed Apparatus for Vending Stamps, Labels or the like
Inventor: ABEL WILLY
Filed: 1903-09-10
Granted: 1904-09-08
Abstract: 19,533. Abel, W., Strauss, K., and Wollheim, H. Sept. 10. Sale apparatus for postage stamps, labels, and the like. Fig. 1 is a side elevation set on end, and Fig. 4 is an end elevation, while Figs. 9, 14, 20, and 21 are views of details. Actuating-mechanism.-On pulling out a horizontal slide a which is connected by a cross-lever e to a vertical lever 7, the latter is moved in the direction of the arrow, and simultaneously a ratchet lever thrust by the slide is made to drive a cam-wheel 20 in the direction of the arrow upon it. On releasing the slide, it is pulled in again by a spring i the action of which is moderated by a piston k and an air-cushion. The actuation is assisted by a spring strip 92 acting on a stud 91 on the vertical lever. Clockwork acting directly, or releasing a spring, may also be used. Delivery mechanism.-A file of catches 5 on the vertical lever 7 bears on the strip of stamps 1 in a channel 4 and, in the return movement of the slide, by engaging the most forward perforations, feeds the front stamp to a support 29. In the outward movement of the slide, the strip is nipped on the cheeks 31, Fig. 9, of the support 29, and the terminal stamp is severed from the rest, by means of a lever 25, Fig. 4, and a blunt blade 32 working in a guide 28. The cam 20 effects these operations by actuating a lever 21 which is connected to the nipper by a spring 35, and is forced down on the blade. In a modification there are two cams and separate levers for the nipper and blade. To insure the engagement of some of the catches 5 in the perforations of the stamp strip, they are made with staggered notches 88, 89, Fig. 20, or projections as shown in Fig. 21 so as to constitute two or more mingled series which are applied by separate spring bails, or they are applied separately by a spring to each. Fig. 14 shows a wire comb 5 in a block 82 which is raised and lowered by having studs travelling in guide-grooves 83. A weak spring plate 93, Fig. 9, on the inner cheek 31 of the support 29 prevents the free end of the strip from catching the other cheek at the next advance. Coin action; coin-discharging mechanism.-The coin introduced by a shoot 47, Fig. 1, into a slot in the actuating-slide is pulled thereby under a detent 49 with bevelled lip 51 and then escapes down a channel 53. Fraud, preventing.-A reversible pawl insures full strokes to the actuating-slide. Empty machines, locking action of.-A lever, dropping when the last stamp has passed, tilts the coin shoot 47 so that the coins pass clear of the delivery slide to a return-shoot.

Title: Improvements in or relating to Coin-freed Electric Meters
Inventor: ALLAN JAMES
Filed: 1903-11-18
Granted: 1904-08-11
Abstract: 25,114. Allan, J. Nov. 18. Electricity, supplying, in general.-A prepayment apparatus for attachment to electric meters comprises a differential gear, which, on the insertion of coin or coins, may be turned a definite amount, and which is returned to its initial position by gearing connected to the spindle of the meter. The mechanism is shown in front view in Fig. 1, and in side view in Fig. 2. The worm a' on the spindle a gears with the wheel e, with which is mounted a crown-wheelf, gearing through a pinion g with a similar crown-wheel h. The latter is mounted with a pinion i gearing with the counting- mechanism or other rotating part of the meter. The crown-wheels and the carrier k<1>, on whieh the pinion g and a weighted shoe are mounted, are all mounted loosely on the spindle k. When the spindle a is rotated the pinion g moves, while the wheel h remains stationary. The end of the weighted shoe presses against the heel m of the spring-urged lever m<1>, which is thereby displaced and acts on the switch lever n. The roller m<2> on the lever m allows the forked end of a catch lever p to drop and hold the lever in its displaced position. The forward motion of the wheel f may be continued, as the shoe then clears the heel m, until a projection on the carrier k<1> comes against a stop on the lever p, the number of coins used at a time being thus limited. The rotation of the wheel h by the meter, moves the pinion g backwards until an inclined projection k<2> on the carrier meets another projection p<1> on the lever p, and displaces the latter, allowing the lever m<1> to return to its original position. In doing so, the end of the lever engages the tail n<1> of the switch lever and opens the circuit. Actuating-mechanism ; coin action; coin-tipping mechanism.-The coin is placed in a slot in the receptacle b in which it is held until the spindle has been turned by hand to the discharge position. The coin, if of the proper size, prevents the engagement of the pawl d with the notch c<1>. The spindle is prevented from being turned backwards by the notches c and pawl d.
