Ethinylation catalysts include alkali metal hydroxides, amides or alcoholates, strong organic bases such as piperidine, and heavy metals of the first group of the periodic system and their acetylides and compounds capable of forming acetylides.  Heating or cooling may be necessary, and the use of inert solvents such as ether, tetrahydrofuran, dioxan or acetals is advantageous. Hydrogenation of the acetylenic carbinols to the corresponding ethylenic compounds may be accomplished by the aid of Raney iron, and hydrogenation to the corresponding propane derivatives with Raney nickel.  Acid addition and quaternary ammonium salts of the carbinols and particularly their hydrohalides and methohalides are referred to.  In examples (i) 2-cyclohexylidene - 1 - (31 - piperidinopropynyl)-cyclohexanol hydrochloride is prepared and is then hydrogenated in the free base form in the presence of Raney nickel to give 2-cyclohexylidene - (31 - piperidino - propy) - cyclohexanol from which the hydrochloride is prepared; (ii) 2-cyclohexylidene - 1 - (31 - diethylamino - propynyl) - cyclohexanol is prepared and then converted to its methiodide; (iii) and (iv) 2-cyclohexylidene - 1 - (31 - pyrrolidinopropynyl)-and 2 - cyclohexylidene - 1 - (31 - hexamethyleneiminopropynyl) - cyclohexanone are prepared.

Title: Improvements in or relating to the manufacture of bodies from metals having a high melting-point
IPC: C22F1/18
Filed: 1922-03-24
Abstract: 200,879. Wade, H., (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). March 24, 1922. Annealing; cementation.-Ductile bodies of refractory metals, such as tungsten, molybdenum, or tantalum, are obtained by heating a single crystal of metal in an atmosphere of a volatile and dissociable compound of the refractory metal at a temperature between about 1200‹ and 2400‹ C. the dissociated refractory metal settling on the crystal so that the latter increases in size whilst remaining a single crystal. The body so obtained may then be subjected to mechanical treatment, such as rolling, hammering, or drawing, to obtain the metal in the form of rods. ribbons, wire, or filaments for electric lamps. The original crystal, which may be obtained by any known process, such as that described in Specification 16620/14, instead of being of the same material as the ductile body may be of another metal or alloy isomorphous with the ductile body, in which case the core may afterwards be removed in anv known manner. The atmosphere in which the dissociation takes places may also contain small quantities of substances. such as iron, nickel, phosphorus, or silicon, which will form a single crystal with the refractory metal, these substances being added in the form of volatile compounds. In one device suitable for carrying out the invention, a 'tungsten crystal 4 is supported between two tungsten rods 3 and is electrically heated to about 1500‹ to 1600‹ C. in an atmosphere of tungsten chloride contained in a previously exhausted vessel 1, which also contains a cup 6 filled with tungsten powder electrically heated to about 300‹ to 500‹ C. The vessel 1 is contained in a furnace 8 which is maintained at such a temperature that the tungsten chloride does not condense on the walls of the vessel 1, this being effected by any suitable means such as by a current of hot air entering a conduit 11 and leaving through a conduit 12.

Filed: 1926-04-01
Abstract: 250,256. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Peterson, H. 0.). April 2, 1925, [Convention date]. Directive signalling; aerials; thermionic amplifiers and detectors.-A system for directive reception comprises a loop aerial earthed at its mid-point and connected at its opposite ends to the electrodes of a pair of amplifiers arranged in push-pull relation, the connections being such as to balance the effects of internal capacity in the valves. The loop and its earth connection may also function as a vertical non-directional aerial, and the relative values of the directional and non-directional effects may be adjusted so as to vary the form of the polar directive diagram. The loop aerial M, Fig. 2, is tuned by a condenser C<1> and its mid-point O is connected to earth G' through a tuning coil N. An open aerial may also be attached at 0. The ends of the loop are connected to the grids of the push-pull pair of valves A, B, the common filament circuit of which is earthed at G<2>. The plates of the valves are connected to opposite ends of a transformer primary coil P<1>, which has its mid-point connected to the plate battery H through the primary P<2> of a second transformer. The secondary coils S<1>, S<2> are connected in series or other relation, and jointly affect the detector. Stabilizing condensers CA, CB are connected between the plate of each valve and the grid of the other. Received currents flowing round the loop excite the two grids in phase opposition, and affect only the secondary S<1>; whilst currents flowing between the loop and earth excite the two grids in phase agreement, and affect only the secondary S<2>. By varying the coupling of S<1> or S<2>, the relative values of the loop effect, and the vertical-antenna effect, can be adjusted. The Specification as open to inspection under Sect. 91 (3) (a) refers also to a transmitting circuit similar to that described above for reception except that the plates of the valves are connected to the ends of the loop M, and their grids are connected to the coils P', P<2>. The exciting oscillations are applied to the grid circuits from the circuit S<1>, S<2>. A circuit is also described in which the mid-point 0 is earthed directly, and the coil N, the balancing-condensers CA, CB and the transformer P<2>, S<2>, are omitted. This subjectmatter does not appear in the Specification as accepted.

Title: Process for the manufacture and production of new condensation products of the benzanthrone series
IPC: C09B3/06
Filed: 1928-03-24
Abstract: 319,593. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). March 24, 1928. Samples furnished. Benzanthrone derivatives.-Condensation products of the benzanthrone series are obtained by treating a mixture of a benzanthrone having a free 2-position and a compound of the general formula X-CH2-R, where X represents a nitrile, acid amido, or acyl group, and R represents hydrogen, an alkyl or aryl group, or an esterified carboxylic group, with alkaline condensing agents. The condensation may be carried out in the presence of organic diluents, such as benzene, mono-, di-, or tri-chlorbenzene or pyridine, or an excess of the compound to be condensed with the benzanthrone may be employed as diluent. The reaction may also be carried out in the presence of air or while excluding air, for example in a current of nitrogen. The products appear to contain the group X.CH.R in the 2-position and are converted by the action of alkaline agents into saltlike compounds which furnish intensely-coloured solutions with alcohol or acetone. They are intermediates for the preparation of dyestuffs. In examples (1) acetone is condensed with benzanthrone by means of caustic potash in benzene, or other alkaline condensing agents, such as caustic soda or sodium alcoholates may be used; di-n-propylketone may be used instead of acetone ; (2) acetone is condensed with Bz1-chlorbenzanthrone by means of caustic potash and pyridine; (3) benzanthrone is condensed with acetone by means of caustic potash a large excess of acetone being employed; (4) acetophenone, acetone, acetonitrile, the ethyl ester of cyanacetic acid, benzyl cyanide, phenylacetamide, propionitrile, and nbutyronitrile are condensed with benzanthrone by means of caustic potash.

Patent GB-395460-A (GB)
Title: Improvements in vacuum brake apparatus for railway and other vehicles
IPC: B60T13/46
Filed: 1932-03-29
Abstract: 395,460. Vacuum brakes. CONSOLIDATED BRAKE & ENGINEERING CO., Ltd. and RAWLINGS, V. P., Windsor Works, Slough, Buckinghamshire. March 29, 1932, No. 9064. [Class 103 (i).] Vacuum brake apparatus for railway vehicles comprises for each cylinder or group of cylinders a valve device controlled by the vacuum in the train-pipe, in the lower brake cylinder chamber and a constant vacuum chamber and controlling the connection of the cylinder chamber with the train-pipe and the atmosphere whereby in applying the brakes the reduction in the train-pipe vacuum is less than that effected thereby in the cylinder chamber and in release the cylinder chamber is connected to the relatively high vacuum that is thus retained in the train-pipe. Chambers 4, 2, 18 are constantly connected respectively to the trainpipe 16 (by a port not shown), to the lower brake cylinder chamber and to the atmosphere. The constant vacuum chamber 3 is normally connected to the train-pipe through the valve spindle 9 by the port 24 and passage 27, a ballvalve 29 being provided if desired. The spindle 9 is connected to the diaphragm 5 but can slide with respect to the diaphragm 6. The end 10 of the spindle is normally raised from the valve 7 as shown so that the brake cylinder is connected to the train-pipe through the spindle. The cylinder has the usual ball-valve fitting for closing the upper cylinder chamber when the brakes are applied. When air is admitted to the train-pipe and chamber 4 to apply the brakes, the diaphragm 6 first moves downwards alone to close the chamber 3 by seating the valve 14, 23, both diaphragms and the spindle 9 then move to engage the end of spindle 9 with the valve 7 thus shutting off the cylinder chamber 2 from the train-pipe and opening it to the atmosphere chamber 18. When the pressure in the cylinder and chamber 2 has risen to a value corresponding to that in the train-pipe chamber 4 the diaphragms and spindle 9 move upwards until the valve 7 closes, the chamber 2 remaining cut-off from the train-pipe. The vacuum in the lower cylinder chamber may thus be gradually reduced and as the diaphragm 5 is smaller than the diaphragm 6 this reduction is greater than that in the train-pipe. When the train-pipe is exhausted to release the brakes, the end of the spindle is again lifted from the valve 7 so that air flows through it to the train-pipe from the cylinder and chamber 2 and as the vacuum in the train-pipe is relatively high, a rapid release which may however be graduated is obtained. The chamber 3 may be connected to a reservoir which is directly connected to the train-pipe through a non-return valve, the connection of the chamber through the spindle 9 being dispensed with.
