Title: Improvements in and relating to valves for engines and the like
IPC: F01L1/32
Filed: 1935-03-04
Abstract: 453,201. Valves. TERKELSEN, S. K., Billum, Bangil, Java. March 4, 1935, No. 6743. [Class 135] [See also Group XXVII] In a valve for internalcombustion engines, steam engines, pumps or the like, helical vanes d which taper conically towards the valve spindle c are provided below the valve b so that the flow of fluid causes rotation of the valve to clean and grind the seating surfaces. The loading- spring f presses at one end against a plate g bearing against a plate j on the valve spindle c, balls h being interposed between the plates so that the spring pressure does not impede the rotation of the valve. For the same purpose, the connection between the operating rod l and the spindle c comprises a ball-bearing socket m.

[Also in Division H2] A converting circuit comprises controllable semi-conductor rectifiers arranged in parallel paths feeding a common load each path containing one or more rectifiers and which paths are connected in series with current-equalizing reactances, characterized in that a rectifier in one path is arranged to be fed with ignition pulses and that the voltage developed across the current-equalizing reactances in that path is fed to another path or paths to ignite other controllable rectifiers. Fig. 1 shows part of a converter system with two parallel paths. Each path contains two semi-conductor controllable rectifiers 1, 2, 1<SP>1</SP>, 2<SP>1</SP>, the rectifiers 2, 2<SP>1</SP> having protective diodes 25, 26. In operation, a pulse applied to transformer 21 ignites rectifier 2 and capacitor 10 discharges through the gate electrode of rectifier 1 so this also ignites. The resultant current in the inductor 15 causes a voltage which via capacitor 14 ignites rectifier 2<SP>1</SP> and allows capacitor 12 to discharge, thus igniting rectifier 1<SP>1</SP>. The transformer 21 may have another secondary winding 24 to supply pulses to the other path. Fig. 2 (not shown) illustrates a similar system with three parallel paths.

Patent GB-327832-A (GB)
Title: Improvements in and relating to sanding apparatus for railway and the like vehicles
IPC: B61C15/10
Filed: 1929-03-06
Abstract: 327,832. Muller, M. March 6, 1929. Sand, distributing on wheel tracks.-In a sanding apparatus for railway &c, vehicles a magnet, which may also act as a rail brake magnet, is adapted to conduct sand to a rail, being guided over the rail by the rail itself. In one form, the outlet end of a pipe 7, Fig. 1, conducts sand from a sand-box 10 to a rail 2 through a recess 6 in a magnet 3 which, when energized, is attracted towards the rail 2 opening a valve 11 by means of an angle-lever 9, so that sand is supplied to the surface of the rail, springs 12 and 12<1> moving all the parts back to their original positions when the magnet is de-energized. In a modification the magnet is displaced by its contact with the rail so that the sand-pipe is brought over the recess of the magnet, the pipe being arranged to draw the energized magnet along with the vehicle. In Fig. 3A the magnet, suspended from the vehicle by connecting-rods 24, 25, is provided with a fixed pole 4 and a movable pole 4 so that only the movable pole 4 fixed to the sand-pipe 7 is attracted towards the rail, against the action of the compression spring 23. For high speeds the magnet 3, Figs. 5A and 5<B>, forms a relatively long channel over the rail, the poles 4, 4<1> of the magnet being arranged side by side, instead of one behind the other, and having the channel 5 between them. The magnet 3 carries a funnel 31, in communication through a pipe 32 with the channel 5 which is closed at its forward end. The movement of the magnet may be used to open the sand outlet. The energization of the magnet may only effect the engagement of the latter with the rail, while the release of sand may be effected either by hand, as indicated by the arrow in Fig. 1, or by means of a separate magnet. The rail-magnets may be energized by the traction current or by the braking current should electrical brakes be provided, or a separate current source may be used. A circuit is illustrated in which the braking current is utilized to operate an automatic switch, the sandmagnet and the rail-magnets working independently of one another, if necessary, by means of a hand-switch. The distance of the magnets from the rail may be altered as desired as by a system of levers.

Abstract: Vat dyes are obtained by condensing an aminoanthraquinone with a naphthalene or perylene tetracarboxylic acid-diphenylimide containing a carboxylic halide substituent in each phenyl radical. Any nucleus of the reacting compounds may be substituted by simple groups such as halogen or alkyl.  The products are yellow to blue-red dyes.  The naphthalene or perylene tetracarboxylic acid diphenylimides with carboxylic halide in the phenyl nuclei may be obtained by condensing an aminobenzoic acid with a naphthalene or perylene tetracarboxylic acid, or anhydride and treating with thionyl chloride.  According to examples, (1) the acid chloride obtained by condensing m-aminobenzoic acid with perylene tetracarboxylic anhydride and treating the product with thionyl chloride, is condensed with 1-amino-4-methoxyanthraquinone to give a scarlet cotton dye, and with 1-amino-4-benzoyl-aminoanthraquinone to give a bluish-red dye; (2) the acid chloride obtained by condensing m-aminobenzoic acid with naphthalene tetracarboxylic acid treating the product with thionyl chloride, is condensed with 1-aminoanthraquinone to give a yellow cotton dye.  The products are aroylaminoanthraquinones.
