Title: A railway and gun carriage arrangement for railway guns, permitting of the lateral training of the gun carriage
IPC: F41A23/40
Filed: 1920-07-02
Abstract: 146,326. Krupp Akt.-Ges., F. May 21, 1918, [Convention date]. Sidings and junctions, tracks for.-Relates to rail arrangements for railway gun carriages which permit of traversing the gun by moving the carriage bogies along the rails, and consists in providing a circular set of rails on which one or both sets of bogies can be moved to give an all-round traverse. The gun carriage consists of a frame C on bogie sets D, E each comprising a large number of separate bogies which run on the circular set of rails A coupled by stays b<1> to a central platform B. When it is desired to traverse the gun the carriage is backed on to the circular track from an approach line a<1>. A traversing car J coupled to the bogie sets by links i<1> is employed for moving the carriage round the track. Figs. 5 to 7 show how the circular track is employed for traversing gun carriages of various lengths.

Title: Line space lock release mechanism for typewriting adding machines
IPC: B41J3/28
Filed: 1931-06-24
Abstract: 373,457. Typewriters. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Elliott- Fisher Co. ; Cedar Street, Harrisburg, Pennsylvania, U.S.A.) June 24, 1931, No. 18298. [Class 100 (iv).] Line-spacing mechanism.-In a flat-platen typewriter of the kind described in Specification 312,136, [Class 100 (iv), Typewriters &c.], in which the line-spacing mechanism is auto'- matically actuated by the carriage return and is then locked, means are provided for releasing the line-space lock' in different marginal positions of the carriage, the release being either manual or by movement of the carriage. In the mechanism in Figs. 3 and 4, a hook member' 17 mounted on the carriage engages, at the end' of the carriage-return movement with a member 19, adjustably mounted on a sliding rod 15, and the consequent movement of the rod 15 operates and then locks the line-space mechanism. The release mechanism comprises a cam carriage 30, adjustably mounted on a sliding rod 29, and provided with a spring- urged pivoted cam 34, Fig. 10, having cam inclines 38, 39. At the end of the carriagereturning movement, a pin 37 on the' hook 17 passes over the incline 38 and on to the incline 39 and, during the initial letter-spacing movement, the incline 39 co-operates with the pin to release the line-space lock. A rod' 53 is coupled by a lever 49 to the drive-control axle 24 for the traversing mechanism, described in the above-mentioned Specification, so that the longitudinal movement of the axle 24 moves a lever 41 through the rod 53. A lever 42 is coupled by a member 47 to the rod 29 and is actuated by the lever 41 through a member 43 or a pin 45 in such a manner that motion of the lever 41 in either direction actuates the lever 42 and the rod 29 so as to release the linespace lock by the co-operation of the pin 37 and incline 39. A margin stop 9 is adjustably mounted on the carriage space rack 8, and co-operates with a spring-plunger on the carriage.

A container 1 for irradiated fuel elements comprises an outer tubular part 2 having an open upper end 3 and a lower end 4 closed by shielding 18 and an inner tubular part 6 having an open lower end 7 and an upper end 8 closed by shielding 19, a fuel element magazine 9 being removably mounted on a spindle 11 supported by the end 4. The part 6 is supported by the part 2 through a rubber joint ring 26 so that cooling water may be retained in the magazine chamber 47 formed by the shielding wall 22 of the part 6. A spindle 14 fixed to the upper end of the magazine has radial fins (Fig. 4, not shown) received in open-ended slots in a sleeve 13 rotatable in the end 8 whereby the magazine may be rotated by a shaft 36 having a pinion 35 meshing with a gear-wheel 34 rigid with the sleeve and the magazine compartments 10 may be brought in turn beneath a fuel element loading port 27 in the end 8. A shielded valve 28 controlled by a spindle 30 is movable in a recess 29 in the end 8 and enables the port 27 to be closed. The container 1 is intended for transferring fuel elements from a ship-borne reactor into a water-filled tank in a barge alongside the ship. In use, spent fuel elements are loaded into the magazine by a refuelling machine and after closure of the valve 28 a crane lifts the container by lugs 40 attached to the part 2 into the barge tank. When the water level is adjacent the lugs 40 pivoted clamps (Fig. 1, not shown) holding together the parts 2, 6 are released and the container is lowered further until it is supported by the tank bottom. The crane is released from lugs 40 and attached to lugs 41 on the part 6 and removes the part 6 from part 2. A grab then grips the spindle 14 and lifts the magazine 9 clear of the spindle 11 and withdraws the magazine sideways through one of the side openings 5 in the part 2 and deposits the magazine on the tank bottom.

Patent GB-239178-A (GB)
Title: Process for producing fatty acids from hydrocarbons
Filed: 1925-07-21
Abstract: In the process of oxidizing hydrocarbons to fatty acids by means of oxidizing agents, with or without catalysts, the fatty acids, including those of high molecular weight, are distilled away by means of steam, preferably super-heated, during the oxidation.  The oxidation may be carried out by means of air or oxygen, which may be mixed with the steam or applied separately. The reaction is performed at temperatures over 160 DEG  C., and preferably between 200 DEG  and 250 DEG  C.  In an example, steam and oxygen are passed into paraffin heated to 180 DEG  or 200 DEG  C. with strong stirring, oxygen being first used, and super-heated steam being led in either separately or mixed with oxygen after the reaction has started.  External heating may be stopped after the reaction has set in, the temperature being regulated and maintained at about 250 DEG  C. by the heated vapour and gas.  The distillate separates into a watery layer containing acids of low molecular weight, and a solidified mass of acids of high molecular weight.  The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of other inert gases for driving off the fatty acids in place of steam.  The oxidation and expulsion of the fatty acids may, for example, be carried out by the use of air above, the air being passed into the reaction mixture in a highly heated condition.  This subject-matter does not appear in the Specification as accepted.

[Class 38 (v)] Electromagnetically - operated mercury switches of the type having a displacer which, upon energization or de-energization of a relay coil, is magnetically shifted within a switch envelope, which envelope is supported vertically in the legs of the yoke of an electromagnet, for causing movement of the mercury to make or break an electric circuit through electrodes inserted into the envelope, are made with the switch envelope extending within one or more pole sleeves of magnetic material separate from the yoke legs, which sleeves closely fit the switch envelope and are supported against the yoke legs to constitute an extension or extensions thereof. As shown in Figs. 1 and 2, the operating winding 17 surrounds a switch envelope 10 in which a magnetic displacer 16 has its lower end dipping in mercury. A magnetic yoke 26 is provided for the winding which has horizontal limbs 24, 25 to the ends of which are clamped tubular polepieces 21, 22, the inner ends of which are separated by an air gap so arranged that when the winding is energized the displacer 16 is raised and the level of mercury falls below the end of a central electrode 12 which projects through an insulating sleeve thus breaking the circuit between this electrode and a lateral electrode. Alternately, Fig. 3, (not shown), the displacer may be arranged to be attracted downwardly into the mercury on energization of the operating coil the consequent rise in level of the mercury causing the bridging of two electrodes. The glass envelope is filled with an inert gas and springs above and below the displacer prevent damage to the envelope by movements of the displacer. The envelope is detachably held in position by a non-magnetic spring clip 37 allowing it to be readily withdrawn. The polepieces are secured to the yoke by non-magnetic clips 23 and are longitudinally slit to prevent formation of eddy currents therein when an A.C. operating supply is used. A number of switches may be arranged in a single assembly and a single operating coil may be arranged to energize simultaneously the yokes of a complete assembly, Fig. 4, (not shown).
