Title: Improved triple valve for direct acting automatic brakes
IPC: B60T15/30
Filed: 1930-05-03
Abstract: 354,213. Fluid - pressure brakes. KASANTZEFF, F., 11, Lietzenburgerstrasse, Berlin. May 3, 1930. No. 13699. [Class 103 (i).] In a triple valve in which the brake cylinder pressure is controlled by this pressure and a regulating pressure inversely corresponding to trainpipe pressure, a chamber connected to the brake cylinder has large inlet and outlet ports and the regulating pressure chamber has relatively small inlet and outlet ports in order to produce comparatively slow changes in regulating pressure to obtain approximately simultaneous brake application throughout the train. The regulating pressure is produced in a chamber 2 by a valve 15 which admits air from the narrow auxiliary reservoir passage 19 and a narrow passage 20 to chambers 5, 2 when train-pipe pressure in a chamber 7 falls. This increased pressure in the chamber 5 acts on diaphragms 10, 12 and recloses the valve 15. Constant pressure in a reservoir acts through a passage 23 in a chamber 8 on the diaphragm 12. Chamber 6 is connected by a passage 21 to the atmosphere and to the chambers 5, 2 past the valve 15 when the apparatus is charged and the brakes released. The diaphragm 12 conveys its movement, due to variations of train-pipe pressure to the diaphragm 10 by means of a casing 16 and an abutment 18 pressed by a spring 17 against a stop in the casing and a hub 13 fixed to the diaphragm 10 and extending with a close fit through an extension of a wall 11 of the valve casing. To prevent too great a rise in regulating pressure if the trainpipe pressure drops too rapidly, the spring 17 is adapted to become compressed by the hub 13 which is maintained in position by the pressure in the chamber 5. The increased regulating pressure on brake application in the chamber 2 raises the diaphragm system 34, 35, 36 which opens a valve 52 and admits fluid from the passage 19 to a chamber 32 connected to the brake cylinder. This increased pressure acting on the diaphragm 36 recloses the valve. In release position a passage 51 in the hub of the diaphragm connects the chamber 32 to an atmospheric chamber 30. This passage is closed by the valve 52 on brake application. A chamber 31 between diaphragms 35, 36 is adapted to be connected to atmosphere or the chamber 32 by a cock 40 according to whether the vehicle is loaded or empty, to render the diaphragm 35 or the diaphragm 36 ineffective. On charging, train-pipe air passes by a passage 22, 46, check valve 47, passage 19, and a bore 49 in a check valve 48 to the auxiliary reservoir and past a valve 24 and through a passage 23 to the constant pressure reservoir and chamber 8. The valve 24 is closed by brake cylinder pressure in the chamber 32 acting on a diaphragm 25, on brake application.

Title: Improvements in and connected with the control of electrically ignited gas burners
IPC: F23Q9/08
Filed: 1934-05-09
Abstract: 419,715. Fluid - actuated valves. GAWA PATENT - VERWALTUNGS AKT.- GES., Schaffhausen, Switzerland.-(Assignees of Frister Akt.-Ges., R. ; 63, Edisonstrasse, Oberschõneweide, Berlin.) May 9, 1934, No. 14017. Convention date, May 9, 1933. [Class 135.] In a gas burner installation for a liquid heater with an electrically-ignited auxiliary jet e for igniting the burner B, the opening movement of the liquid cock, or the movement of a control device produced by the starting of the liquid flow, closes the circuit of an igniter d<1> and admits gas to the jet e, a thermal device i, heated by the jet, being mechanically operative for controlling the opening of the valve r of the burner B. The movements of the device i may be imparted directly or indirectly to the valve r. In the arrangement shown in Fig. 1, the diaphragm a of a liquid deficiency safety device is depressed when liquid flows in the pipe b and a rod c thereon closes contacts d and opens a valve g so that gas flows from the pipe G through a chamber p and pipes f, h to the jet e and is ignited. The device i is distended as shown and the spring-pressed valve rod k moves to break the circuit at a contact m and open the valve. Gas then passes from the chamber n through a pipe l to a jet s to provide a safety flame in the event of the liquid flow being stopped and immediately re-started and the diaphragm q is depressed to open the valve r. If the liquid flow be stopped, the rod c is raised by the diaphragm a to close the valves r, g. In a modification, the movement of the diaphragm a opens a main gas valve so that gas passes through the upper chamber of a diaphragm q, Fig. 2, and a pipe f<1> to the jet e. When the valve k is opened, gas passes through the lower chamber of the diaphragm q and a pipe l<1> to the safety jet s and the diaphragm q is depressed to open the valve r. The main valve is byepassed by a pipe v, connected to the pipe l<1> or with a port in the casing of the valve k, to maintain the safety flame until the valve k is closed.

Title: Improvements relating to the deodorisation or like treatment of fumes and gases
IPC: B01D53/52
Filed: 1928-05-16
Abstract: 314,187. Vernon, J. W. May 16,1928. Deodorizing air and gases. - Fumes and gas containing sulphur or gaseous sulphur compounds, such, for instance, as those involved in the manufacture of artificial silk or coal gas or in the treatment of tank waste in the alkali industry, are subjected to the action of sulphuric acid of at least 82 per cent concentration and preferably in the form of a mist or spray. The gases are caused to meet a spray or mist of sulphuric acid in a conduit, and the liquid falls to the bottom where any sulphur deposited is removed by filtration, the acid being then reconcentrated for further use. The gases are subsequently subjected to a water spray to complete the removal of sulphur compounds and to remove any acid. The reactions may be accelerated by first spraying the gases with water at about 95‹ C., and maintaining the acid at 80‹-95‹ C..In the treatment of coal gas, unsaturated hydrocarbons other than ethylene are first removed by sulphuric acid of less than 82 per cent strength, and the sulphuretted hydrogen and organic sulphur compounds, including thiophene and its derivatives, are removed as above. According to the Provisional Specification. the fumes are first treated with concentrated sulphuric acid and subsequently with dilute acid.

Title: Continuous process for the bleaching of cellulosic textiles
IPC: D06L4/24
Filed: 1953-05-21
Abstract: Cellulosic textiles in band form are subjected to a continuous bleach in a solution at an elevated temperature, e.g. 60 DEG  to 100 DEG C., of an alkali or alkaline earth chlorite, which may be activated, the material being repeatedly and thoroughly penetrated by the bleaching liquor for a relatively short period, e.g. 3 to 25 minutes, then excess liquor being removed by squeezing.  The material is passed into a closed heat-insulated chamber in which it is laid in regular folds and through which the material passes continuously, each individual fold remaining in the chamber for a period of 5 to 15 times as long as that for which the corresponding portion of the material was subjected to the bleaching treatment.  The material may be regenerated cellulose or cotton.  The bleaching liquor may comprise a solution of sodium chlorite and sodium pyrophosphate, the pH being adjusted with formic acid to 3.8 to 4.0.  The bleaching apparatus is such that the material forms a series of loops arranged side by side with their lower parts dipping in the bath, the ascending side of each loop passing through a pair of squeeze rollers disposed above the surface of the bath and a pair of squeeze rollers being provided to free the material leaving the bath from excess liquor which is returned to the bath.  Prior to bleaching the material may be desized or wetted.

Title: Improvements in or relating to the production of artificial fibres
IPC: D01F2/28
Filed: 1938-05-13
Abstract: 514,736. Artificial fibres. GASTELL, R. SCHREIBER-, and FORMHALS, A. May 13, 1938, No. 14365. [Class 2 (ii)] Artificial fibres are obtained by extruding a filament-forming solution through one or more jets which form one electrode of a high tension electrical circuit, into an electrical field created between the jets and an electrode forming the other pole of the high tension supply. The solution is disrupted by the electrical forces into fine fibres and these are removed from a position between the two electrodes without coming into contact with the other electrode. The filament-forming material may be extruded into an air current substantially at right-angles to the direction of extrusion. The spinning solution may be a solution of cellulose acetate or other cellulose ester in a volatile solvent such as acetone. The electrical connection with the jet-electrode may be made at any convenient point since the solution is a conductor of high-tension electricity. The other electrode may consist of one or more thin wires or knife-edged blades connected to the opposite pole of the high tension supply. The wire may be fixed below but preferably not directly underneath the jets. As shown in Figs. 1 and 4, x1, x4, represent cross-sections of wires forming one of the electrodes and j1, j4, indicate jet electrodes. Preferably, the jet electrodes are made negative. A current of air may be caused to flow between the row of jetelectrodes and the other electrode and substantially parallel to both. As shown in Fig. 5, thin streams of solution are extruded through the orifices in the jets i which form the negative electrode of a high tension electric circuit. The positive electrode is formed by a thin wire x. A current of air is passed between the electrodes from an inlet a. Air and solvent leave the apparatus by the pipe b. The electric current used is a direct pulsating current. The electrical field causes the streams of solution to be split up and formed into fine fibres. The thin wire electrode causes the air in its vicinity to be ionised.. The fibres charged with electricity are attracted towards the wire but when they reach the ionised zone tneir charge is neutralised and then reversed so that they are repelled from the wire. A band of felted fibres is thus formed. This is removed from the apparatus by a winding device u assisted by the air current. The operation may be started by means of a thread arranged to run through the spinning zone in the path taken by the fibre band. If desired, the fibres may be allowed to fall to the floor where they collect as a tangled mass. This may be used as heat insulating material or converted into yarn after carding and other treatments.

Title: Process for reclaiming used lubricating oils
IPC: C10M175/00
Filed: 1935-05-16
Abstract: <PICT:0448009/III/1> Used lubricating-oil is treated with acid, and after recovering the sludge, the oil is neutralized, mixed during or after neutralization with fuller's earth, and the mixture is heated in a closed chamber to distil off moisture and eventually one or more of the light components, sufficient pressure being developed to prevent cracking.  As shown, used oil in a vessel 1 is first treated with sulphuric acid, the mixture being agitated by air admitted through a pipe 5.  After settling and removal of sludge through a valve 2, lime and fuller's earth are added and the mixture again agitated.  The mixture is then run off through a valve 58 and pipe 28, adapted to be coupled through a union 30 to a valve 25, into a rotary still described in Specification 450,822, comprising a drum 8, adapted to be oscillated by segmental gearing 10, 50 and heated by a burner 18.  When charged, the valves 58, 25 are closed, the union 30 disconnected and the drum set into oscillation, and heating continued up to 350 DEG  F.  A cam 37 is then adjusted to contact with the head of a spring-actuated valve 33 so as periodically to release the pressure and permit escape of steam through vents 22, 21 to a condenser 24.  The cam 37 is then retracted and the temperature raised to about 550 DEG  F., to drive off light oil vapours which are similarly released through the vents 22, 21.  Preferably a light cut of lubricating oil is removed by raising the temperature further to 700--750 DEG  F.  After removing the desired number of components, the mixture is run off into a cooler 27 from which it is removed by a pump 54 and forced through a bag filter 55, the reclaimed oil passing off through a conduit 57.
