Title: Improvements in Brake Mechanism for Railway and Tramway Rolling Stock and for other uses.
IPC: F16D66/02
Filed: 1917-01-03
Abstract: 111,742. Birmingham Railway Carriage & Wagon Co., and Holloway, H. H. Jan. 3, 1917. Blocks; compensating for wear.- Excessive play in vehicle brake mechanism due to wear of the brake blocks is taken up by automatic adjustment of. the block. According to the arrangement shown, a wedge block F is interposed in the brakeblock holder B between the block and a block G on the pin E which connects the push rods or brake beam to the block, and this pin E is arranged to slide horizontally in the block-holder. A pin 25 on the blockholder engages an eye 33 in a regulating bar H adapted to slide in guides 28 on a plate I fixed to the vehicle framing J. Movement of the bar H away from the wheel is prevented by a pair of friction detente 26, 27. If, in applying the brakes, the movement of the blocks, owing to wear having taken place, exceeds that allowed by the eye 33 in the bar H, this bar is carried towards the wheel with the block. During the release of the brakes, the block and its holder can move away from the wheel only the distance allowed by the eve 33 in the bar H and as the mechanism is moved to the same extent as during the application of the brakes the pin E and its block G slides away from the block against the spring 19 disposed in the holder B and the block F is forced down by the spring 11 to take up the excess play. The drawings show the arrangement for the bogie of a railway or tramway vehicle. The brake blocks are supported from the vehicle framing 7 by links D<2> through which the pins E on the brake beam pass and rollers 9 on the links working in guides 10, 10<x> on the block-holder B give further support to the blocks and prevent rotation thereof about the pin E. The release position of the mechanism may be determined by a stop 56. formed on the links for abutment against the framing 7. The blocks A are secured to the holder B by conical screw pins 1. The eye 33 in the bar II is of sufficient vertical length to allow of the vertical displacement of the brake block with the vehicle framing on the bearing springs and when, as shown, the brake blocks are hung low the eye, 33 must be tapered to allow for the varying amount of play the blocks require according to their vertical displacement. As shown in Fig. 1, the wedge block F and application block G have interengaging teeth, but if a finer adjustment is desired than is thus permitted, the faces of these blocks may be smooth and upward movement of the block F during applications of the brake be prevented by a friction detent device of the kind (26, 27) provided for the regulating bar H. Application of the invention to a wagon (shunter's) brake is described also in which the pins E pass through the usual push rods connected to arms on a tumbler shaft operated by side levels.

Title: Improvements in radiator vent valves
IPC: F24D19/08
Filed: 1922-01-03
Abstract: 193,219. Dehn, F. B., (Leskole Air Valve Co., Inc.). Jan. 3, 1922. Fluid-actuated valves; ball and float valves.-A radiator vent valve is provided with actuating means whereby the valve is open to admit air when the radiator is out of action, and remains open on starting whilst air is escaping, but is closed when the steam arrives and held closed, in part, by surface tension due to water of condensation. The port 1 of the valve is connected to the radiator, and air escapes through a vent 18. The valve 19 controls a port in the bottom of a cup 5, and its spindle 15 carries an inverted cup 21. The upper part 11 of the casing is concave to deflect fluid downwards towards the outlet 13, and the casing is surmounted by a cap 18. The perforated disc 20, closing the cup 21, is provided with a downward flange 22 leaving a narrow annular space between the flange and casing. Alternatively, a flat disc 20<1>, Fig. 3, may be used in place of the cup 21. When the radiator is started, air first escapes, and then steam, which condenses and collects in the cup 5. Further flow of steam passing through the water in the cup 5 closes the valve by impulse, and the valve is held closed by surface tension between the flange 22 and the casing, the fluid pressure being in itself insufficient to hold the valve closed. In the event of a large flow of water from the valve, the cup 21 is lifted and the valve closed by flotation.

Title: 3-substituted 1,4-naphthoquinones
Filed: 1951-01-02
Abstract: The invention comprises the following steps in the manufacture of 3-hydroxy-2-carboxyalkyl-1:4-naphthoquinones:- (1) condensation of a -naphthol with an aliphatic, aryl-aliphatic or alicyclyl-aliphatic mono- or di-carboxylic acid with 6-20 carbon atoms, in the presence of boron trifluoride etherate, to give a 1-hydroxy-2-naphthyl ketone; (2) Clemmensen reduction of the ketone (obtained as in (1) by using a dicarboxylic acid) in the presence of an alcohol ROH (R has 5 or less carbon atoms) to give an ester HO-C10 H6-CH2-X-COOR, X being an aliphatic residue, which may have aryl or alicyclic substituents of 4-18 carbon atoms in all; (3) oxidation of the product of (2) to the corresponding 1:4-naphtho-quinone; (4) treatment of the product of (3) with hydrogen peroxide to introduce a 2:3-epoxide group followed by hydrolysis to give a 3-hydroxy-2-carboxyalkyl-1:4-naphthoquinone; the invention also includes the o - (1:4- naphthoquinonyl-2-) decanoic acid and its alkyl esters in which the alkyl group has 1-5 carbon atoms.  In the examples, (1) sebacic acid is condensed with a -naphthol to give 2-sebacyl-1-naphthol and some sebacyl-bis-naphthol; (2) an alcoholic solution of 2-sebacyl-1-naphthol is reduced with amalgamated zinc and hydrochloric acid to yield ethel o -(1-hydroxy-2-naphthyl)-decanoate, which is oxidized by chromic acid to the naphthoquinonyl-ester; the free acid may be prepared by reduction, hydrolysis and reoxidation and may be converted into the 2:3-oxide and 3-hydroxy compound as described in Examples (3) and (4) for the ester; (3) the ester of (2) is oxidized by hydrogen peroxide to ethyl o -(2:3-epoxy-1:4-diketotetralyl-2)- decanoate; (4) treatment of the product of (3) with sulphuric acid first opens the oxide ring and then hydrolyses the ester group to give o -(3-hydroxy-1:4-naphthoquinonyl-2)-decanoic acid.  This may be degraded to o -(3-hydroxy-1:4-naphthoquinonyl-2)-nonanoic acid by successive treatment with (a) alkaline hydrogen peroxide, (b) acid sulphur dioxide, (c) alkali and copper sulphate and (d) hydrochloric acid; (5) the product of (1) is reduced to o -(1-hydroxy-2-naphthyl)-decanoic acid by catalytic hydrogenation or the Clemmensen-Martin method; the acid is esterified with methanol or ethanol and oxidized to the corresponding naphthoquinone; (6) ethyl o -(1:4-naphthoquinonyl-2)-decanoate is brominated in the 3-position, the bromine is replaced by hydroxyl (e.g. by treatment with sodium acetate) and the ester group hydrolyzed to give the decanoic acid of (4).  In further examples a -naphthol is condensed with the appropriate monocarboxylic acids to give (7) 2- (g -cyclohexyl-butyryl)-1-naphthol, (8) 2 - (g  - p - phenoxyphenyl - butyryl) - 1 - naphthol, (9) 2-lauryl-1-naphthol, (10) 2-myristyl-1-naphthol, (11) 2-(o -bromoundecoyl)-1-naphthol, and (12) 2-stearoyl-1-naphthol. It is stated that these acyl-naphthols may be reduced to alkyl-naphthols and oxidized to naphthoquinones in the same way as the products from dicarboxylic acids.  The production of 2-octadecyl-1-naphthol is described.

Abstract: 554,543. Furnace electrodes. GROVES, W. W. (Moore, W. E.). Jan. 7, 1942, No. 254. [Class 39 (iii)] An electrode column 11 is provided with a crosshead 12 having rollers 13 to engage the column and a split hollow clamping sleeve 14 into which telescopes a tubular arm 16 and an insulating sleeve. A plate 19 closes the end of the arm 16 and carries the clamp for the electrode 10. A contact shoe 22 is bolted between the end of the clamp 20 and the plate 19 and extends upwards for connection to pipes 24 which extend around the crosshead 12 and are adapted to be connected to cooling water supply pipes 27 and electric conductors 28. Connecting pipes 29, 30, 31 are provided to supply cooling water to the arm 16 and electrode clamp. The body 20 of the clamp is of copper and extends vertically in both directions to provide good contact with the electrode, and a flame shield 32 of steel having a relatively higher electrical resistance completes the clamp. The clamp is cooled by steel pipe coils 33. A steel channel 33<SP>1</SP> is secured to the shield 32 opposite the body 20 to receive a steel wedge 36 having teeth 37 to engage the electrode and notches 41 whereby it may be prised up by a tool 42. A finger 40 prevents the wedge from dropping into the furnace. The higher resistance of the wedge-carrying part of the clamp ring prevents burning of these parts to the electrode.
