Title: Improvements in and relating to Hydraulic Rams.
Inventor: GELLY JOSEPH CHARLES
Filed: 1897-12-28
Granted: 1898-04-09
Abstract: 30,638. Gelly, J. C. Dec. 28. Hydraulic rams.-Beyond the usual valve D is a valve D", opening in the opposite direction, and a descending pipe B<1>. When the valve D is closed by the increasing flow, the water in B' moving on produces a vacuum behind it and is ultimately forced back by the atmospheric pressure, closing the valve D" and partly forcing itself through the non-return valve b into the rising main. Several slight modifications are described, and also one in which only the recoil action in the pipe$' is utilized. In another modification, suitable for raising potable water and other liquids by impure water, the latter, instead of being forced when its flow is stopped, moves a water-tight piston, Fig. 6, which acts on the liquid to be forced as a pump piston. In the case of the reservoir X being below the piston, the return stroke of the latter is effected by pressure water admitted between the flexible tube V and the pipe surrounding it.

Patent GB-189812765-A (GB)
Title: Improvements in or relating to the Electrolysis of Liquids and Apparatus therefor.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1898-06-07
Granted: 1899-05-20
Abstract: 12,765. Thompson, W. P., [Hazard- Flamand, M.]. June 7. Oxygen; hydrogen.-Relates to apparatus for the electrolysis of liquids to obtain the two gases given off at the two electrodes without admixture, the gases particularly mentioned being oxygen and hydrogen. An outer metal vessel A forms the negative electrode, and is provided with an outer channel B, and with inner vertical partitions a<1>. Both the partitions and the vessel itself have projecting ribs a, a<2>. If the vessel is made of insulating - material, suitable plates are used as cathodes. Each anode E, having ribs e, is supported by a conducting-bar e' enclosed in a bell e<2> having a paraffin joint. The bell is itself enclosed in an open cylindrical vessel m<2>, formed in one with the lid, and filled with piraffin oil to form a hydraulic joint. The lid M has a depending rim dipping into the gutter B, which contains an insulating - liquid. Between the anodes and cathodes are diaphragms H, so constructed as to lead away separately the two gases evolved. As shown, the diaphragms are built up of a number of annular troughs, which contain the electrolyte, and have depending strips dipping into the trough below, the lowest one dipping into an insulating- dish 1. The diaphragms are supported at each end of the vessel. The highest trough has a deep channel h<1>, into which dip the lower ends of walls m, formed in one with the cover. The gases evolved from the anode and cathode are thus kept separate, and are led away to different outlets, not shown. If the liquid, which for obtaining oxygen and hydrogen is preferably a conducting-solution of an alkali such as soda or potash, is allowed to run short, the gases evolved near the top of the vessel can pass through perforations h<2> and m<2>, and bubbling through the oil in the cylinder m<2> escape to the atmosphere, the bubbling calling attention to the want of electrolyte.

Filed: 1899-08-03
Granted: 1900-05-26
Abstract: 15,886. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. Aug. 3. Neutral esters of carboxyanthranilic acid of the formula C6H4(CO.OR)NH.CO.OR. are produced by acting upon a halogen phthalimide, such as bromo-or chloro-phthalimide of the formula with a cold dilute alcoholic solution of an alkaline alcoholate, and subsequently heating the mixture on a water bath, cooling, neutralizing with hydrochloric acid, rendering slightly acid with acetic acid, distilling off the alcohol, purifying, and distilling in vacuo. The dimethyl ester melting at 60‹-61‹ C., and the diethyl ester melting at 43‹-44‹ C., are thus prepared. Anthranilic acid is produced by boiling one of foregoing neutral esters with solution of barium hydrate, calcium hydrate, or other alkaline earth. The mixture is filtered, subjected to a current of carbonic-acid gas, again filtered, and evaporated to dryness. The free acid is obtained in the usual manner from the barium anthranilate thus produced. Carboxyalkylanthranilic acids are produced by heating one of the foregoing neutral esters with an alcoholic solution of a caustic alkali, distilling off the alcohol, and acidifying the residue. The methyl and ethyl carboxy compounds corresponding to the formula C6H4(CO.OH.)NH.CO.OR. are thus produced. Isatoic acid is produced by heating the foregoing carboxyalkylanthranilic acids with acetyl chloride on a water bath, and subsequently distilling off the acetyl chloride.

Abstract: 16,138. Lones, J., and Holden, E., [trading as Lones, Vernon, & Holden]. Sept. 11. Rolling punching; shearing; work-holders.- A partially formed buffer for a railway vehicle, produced in gapped rolls as described in Specification No. 13,123, A.D. 1889, is passed through two extra passes in the rolls to produce a square end to the circular shank. For ensuring accuracy in rolling, the rolls are geared together as described in Specification No. 12,172, A.D. 1897. The square end is then slotted at the desired length by a loose punch s, Fig. 18, operated by the head of a press k, the punch passing through holes in a divided sleeve i in which the buffer shank a is held by a pinching-screw. The sleeve is carried by an arm g, pivoted at h, which can be swung laterally off the press bed to allow the buffer to be inserted or removed. The position of the slot is determined by a stop n', against which the buffer head d is brought. The weight of the buffer is taken by a crutch p, the arm g being supported by a spring sling l when swung off the bed. After cutting the slot, a cutter blade is placed above the shank in a slot v, and operated by the press head to cut the shank to the desired length, determined by a pivoted stop n'. The shank is then placed in a flared holder, Fig. 22, carried by a slide y on a milling- machine to chamfer the edges of the square end. The holder has a square mouth, each edge being presented in turn to the cutter w, the projection of the shank from the holder being limited by a bent finger or stop x bearing against the end of the shank.
