Granted: 1915-08-05
Abstract: 13,687. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. June 5. Catalytic agents, preparation and treatment of.-In the catalytic oxidation of ammonia to nitrogen oxides, the catalyst, consisting of one or more oxides of the metals of the iron group, is employed in separate pieces or lumps. It is advantageous to heat the pieces or lumps to 600-800‹ C. before use, to prevent sintering of the contact mass in the tube or furnace. The catalyst may be prepared by breaking up an oxidized melt (obtained, for example, by burning metal powder), or by forming the precipitated hydroxides into suitably-shaped pieces, or by breaking up sufficiently pure ores, or by oxidizing pieces or lumps of the metal, or by calcining decomposable salts of the metal such as the nitrate, and breaking up the mass, and by this method a porous catalyst is obtained. Bodies such as sulphur, phosphoric acid, boric acid, silica, and alkali should not be present in the gases or in the catalyst.

Title: Improvements in Apparatus for the Control or Operation of Railway and like Points or Switches.
IPC: B61L5/06
Filed: 1914-06-30
Granted: 1915-08-05
Abstract: 15,642. Siemens, Bros. & Co., [Siemens & Halske Akt.-Ges.]. June 30. Transmission mechanism applicable generally; spring control; electric operation and control.- In railway point or switch actuating-apparatus, the first part of the movement is used to withdraw one of a pair of point-retaining devices and the remaining part is employed solely for the actual operation of the points, the other point-retaining device automatically coming into operation as the movement is completed. In the construction shown, the point motor M rotates the worm 3 which during the first part of its motion slides longitudinally in the bearings 20 owing to the resistance of the point-retaining device 15 against the shoulder 12 on the toothed wheel 8. This movement of the worm withdraws the device 15 by the engagement of the slide B therewith, the worm then driving the wheel 8, which operates the points 11. The retaining-device 17 automatically engages the shoulder 13 at the completion of the movement. A modification is described in which the wheel 8 is replaced by a reciprocating rack having shoulders engaging point-retaining devices. A slip connexion is introduced into both arrangements whereby should undue strain arise damage is prevented. The point-retaining devices are arranged to actuate electric switches C, C<1> for controlling the supervisory and motor circuits.

Title: Improvements in Mine Signalling Apparatus.
Inventor: CHAMBERS STEWART
IPC: B66B19/06
Filed: 1914-11-26
Granted: 1915-10-07
Abstract: 23,105. Chambers, S. Nov. 26. Mechanical telegraphs; bell signals. - A mine signalling-apparatus, combining a visible with an audible signal, has two dials bearing visible orders, and mechanism for operating the same whereby, when an order is signalled, such order remains visible till complied with, whereupon the dials automatically return to their original positions, the arrangement being such that, in the event of the order signalled not being complied with within a reasonable time, it can be repeated without the production of accumulative signals. The inner dial A is mounted on a spindle c, and the outer concentric dial is connected by arms e to a sleeve d working on the spindle c and provided with a counterbalance weight d' and a ratchet disk i. A ratchet-wheel f, freely mounted on the spindle c, has a counterbalance weight f<1> and a projecting pin g which contacts with a corresponding pin h<1> on a ratchet disk h secured to the spindle c and counterbalanced by a weight h<2>, so that when the wheel f is rotated, the disk h also is turned and with it the dial A. The pin g also contacts with a pin i<1> on the ratchet i to rotate the outer dial. The ratchet f is rotated, when the signalling-cord is pulled, by a tooth l on rods k<5> which are raised by bell-crank connexion j, k, k<3>, so that the ratchet f moves one tooth for each pull, its motion being limited by weighted locking-pawls t pivotally secured on the rods k<5> and engaging with oppositely-formed teeth on the ratchets h, i. The ratchets h, i are prevented from returning by pawls which are moved out of engagement by a cam and trip-lever mechanism when the winding- engine starts. A counterweighted pawl m engages the ratchet f to prevent its return, but is adapted to be released by dash-pot mechanism. The ratchet f then returns under the influence of the counterweight f<1> without altering the signal dials, and the order can be audibly repeated. This mechanism also allows the order to be changed, before it is executed, visibly and audibly into another. " Bell - hanging " is indicated by an extension on the top of the rods k<5> made visible through an opening when the rods k<5> are kept in the upper position by the signalling-cord being kept pulled. A stop x on the ratchet f prevents further motion of the same, should more than six pulls be given to the cord.

Granted: 1915-07-29
Abstract: 2633. Wagner, E. Feb. 26, 1914, [Convention date]. Combination tanning processes; leathers prepared from albumins.-A substitute for leather is made from albumins, for example bacteria, ferment-albumin, albumen, glue, or mixtures of these, by tanning the surface with dilute mineral solutions and the interior with vegetable agents, formalin, or mixtures of the same. The vegetable or like tanning of the interior renders it pliable and tough, and the mineral tanning of the exterior makes the surface hard and wear-resisting. The mineral tanning is effected with weak solutions for a short period of time at a temperature of 20‹ C. and below, and the solution is applied by squirting, painting, atomizing, &c. The exterior may be tanned prior to or after the tanning of the interior. In carrying out the process, a foundation of fabric is soaked with the solution of albumins. Vegetable tanning-substances or formalin may be added to the solutions at the beginning or after the mineral tanning, together with media for rendering the material pliant, and with ground leather, factice, colours, castor oil, wood oil, &c. The formalin may be applied in the form of vapour. The graining of the superficially hardened layers of albumins may be performed between the mineral and the vegetable or formalin tanning. The sheet of albumins may also be treated, after hardening with the mineral agent, from the foundation side with vegetable tanning, formalin, or mixtures of the same.
