Title: The Manufacture of New Sulphonic Acids from Indigo Coloring Matters.
Inventor: ELLIS GEORGE BELOE
Filed: 1898-12-16
Granted: 1899-11-11
Abstract: 26,625. Ellis, G. B., [Soc. Chimique des Usines du Rh¶ne, anciennement Gilliard, P. Monnet, et Cartier]. Dec. 16. Dyes, artificial.-Mono- and di-sulphonic acids of the isomeric methyl-indigoes such as are obtained from nitrated m-toluylic aldehyde are prepared by sulphonating these indigoes with sulphuric acid. For example, a monosulphonic acid is obtained by triturating the methyl-indigo derived from nitrotoluylic aldehyde melting at 64‹ C. with sulphuric acid of 98 per cent. and allowing the mixture to stand for 10 hours at 20‹ C. Excess of sulphuric acid is precipitated by chalk or barium carbonate, and the solution is then neutralized with sodium carbonate, filtered, and evaporated to dryness, or the sodium salt is precipitated by sea silt. The disulphonic acids are obtained when fuming sulphuric acid containing 10 per cent. of anhydride is employed at 20‹-30‹ C. They dye greener shades than the monosulphonic acids.

Title: Improvements in and relating to Apparatus for Registering the Arrival of Pigeons in Pigeon Races and the like.
Inventor: REY FELIX
Filed: 1902-02-22
Granted: 1903-02-05
Abstract: 4519. Rey, F., and Rey, H. Feb. 22. Timing pigeons. - Relates to apparatus for registering the arrival of pigeons in pigeon races and the like. Fig. 1 shows a plan view, partially in section, of one form of apparatus. A rotary barrel 1, Figs. 1 and 3, is divided into compartments by partitions 2, each compartment being provided with a radial pin 3 adapted to receive the ring taken from the pigeon's leg. A circumferential guard 4 surrounds the barrel, so that a ring can only be placed on a pin when it is opposite the opening 6. After the ring is in position, the barrel is turned by means of a fixed or detachable key 5, a ratchet - wheel and pawls limiting the movement to the space of one compartment. A pawl is forced aside by the movement of the ratchet-wheel, and actuates a lever 12 on a rocking shaft 13 carrying arms 14, which perforate three dials 15. The dials 15 are driven by clockwork, and record hours, minutes, and seconds, being divided radially, to show the time of arrival of each pigeon, and by concentric circles, to record successive arrivals. The axis of the barrel 1 carries a grooved cam 21, which gives a longitudinal movement to the rocking shaft 13, so that the perforators are moved one step towards the centre of the disc each time the barrel is operated. A balance-wheel 36 with a spring is mounted in the casing, and is arranged so that excessive shaking causes it to engage a catch. The mechanism may be enclosed in a cylindrical casing 34, 33, 35, or in a double rectangular casing with glazed covers, The casings are arranged so that they are automatically locked by turning the barrel 1, and can only be opened when the barrel is in the starting position. The double casing is used to prevent the dials from being tampered with by inserting a wire through a small hole in the casing, such hole being afterwards closed.

Title: Improvements in Gas Meters
Inventor: MEERTS VICTOR
Filed: 1902-03-03
Granted: 1902-05-01
Abstract: 5297. Meerts, V. March 3. Meters. - A gas meter is constructed so as to obviate the necessity for a float or valve. The gas inlet compartment is divided off by a partition. To this partition on the inlet side, are attached two vessels a, o, closed at their bottoms but open at their tops and of the relative heights shown. Within the vessels are receptacles c, d, closed at the tops but open at the bottoms, and forming siphons with the arms e, f respectively. These arms enter the right-hand compartment shown. Water is admitted by the tube i or by the gas inlet to the closed inlet compartment, and rises sufficiently therein to enter the vessels a, b and prime the siphons c, e, and d, f, the result being that both compartments are finally charged up to the level m, m. A small hole l is made in the tube i. Should the level of water fall in the main compartment during the use of the meter, the end of the arm e will first become exposed, and the large amount of water held in the siphon c, e will discharge into the vessel a, thereby entirely closing the end of the gas-discharge tube g, so that the supply of gas through that tube is cut off. There is still, however, a small quantity available for use, namely that passing through the smaller gas-outlet tube h. When, however, the water falls lower still, even that is cut off, as the end of f becomes exposed, and the second siphon discharges its water into the vessel b and closes the mouth of the tube h. The original state of affairs is reproduced by charging the meter with fresh water. The second siphon d, f with its receptacle b and discharge pipe h may be omitted, in which case the gas is entirely cut off as soon as the water falls below the end of the tube e. Or there may be more than two siphons, and there is then a progressive diminution of the light.

Granted: 1903-02-26
Abstract: 7819. Wooldridge, A. J. April 3. Scoring and marking.-Relates to markers or scorers for table tennis &c. The score is registered by rotating toothed wheels c, d, mounted in a case so that one tooth on each extends through openings at the sides of the case. The wheels are marked on both sides with numbers corresponding with the teeth, each number being brought in succession opposite openings in the back and front of the case. Pawls i,j prevent backward movement of the wheels. To indicate the changes of service, a pair of wheels e, f, having ten teeth each and gearing, respectively, with the wheels d, c, are loosely mounted on an axle over an opening in the front of the case, the wheel f being marked 0 and 5, and the wheel e having openings which are turned over one of the figures 0 and 5 when each five points are scored. At the same times, pins secured to the wheel f and fitting in a groove in the wheel e engage the spring clapper of a bell m. Another pair g, h of wheels similarly indicate the changes of service at an opening in the back of the case. On changing the end of service, the scorer reverses the position of the case, so that its right-hand end always corresponds to the same end of the table. An indicator q can be turned, to indicate the end of service. Spring clips are provided on the case, to carry cards bearing the names of the players.
