Title: Improvements in the heat treatment and/or vaporization of hydrocarbon distillates and residues
IPC: C10G11/04
Filed: 1934-04-25
Abstract: <PICT:0428416/III/1> <PICT:0428416/III/2> In the heat treatment of hydrocarbon oils and residues to obtain vapours, which may be subsequently cracked, by distributing the oil over a heated contact or absorptive mass, which is afterwards regenerated by burning off the coke &c. deposited on it, as described in Specification 316,552, [Class 32], provision is made to use the heat generated by the combustion to supply the heat required for the vaporization.  Contact or absorptive material p  such as moulded china clay, broken brick, pumice stone or the material described in Specification 304,654, [Class 1 (i)], is held between horizontal perforated screens 30, 34, Fig. 2, in vessels 6--6<c>, Fig. 1, arranged in pairs in separate insulated chambers 4, 5, those in one chamber being used for vaporization, whilst those in the other are being regenerated.  If the vessels in chamber 4 are being used for vaporization, oil, preheated in an exchanger 7 by the hot vapours being discharged, is passed through a nozzle 8<a> from which it is atomized by superheated steam from a pipe 10 and is discharged through distributers 31--33, Fig. 2, on to the surface of the contact material.  Vapours pass away through the pipe 15.  Meanwhile, air is passed into the vessels in chamber 5 through pipes 12 and is distributed in the contact material by perforated pipes 14, Fig. 2.  The gases of combustion pass by pipe 15<b> into the chamber 5 and hot gases from this chamber are circulated by a pipe 21 which may contain a heater 22 with the chamber 4 and are returned by pipes 24 and a pump 25.  Valves 26, 27 allow escape of excess gases.  Instead of passing the gases of combustion directly to the chamber 5, they may be passed through a circuit such as is described in Specification 414,413.

Title: Improvements in or relating to visual voltage indicators of the electron discharge type
IPC: H03J3/14
Filed: 1938-05-02
Abstract: 514,318. Wireless receiving apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 2, 1938, No. 13062. Convention date, April 30, 1937. [Class 40 (v)] A visual tuning indicator, of the type described in Specification 481,790, is arranged so that the control electrode can become negatively biassed relatively to the cathode, thereby increasing the area or angle of the shadow thrown by the control rod on the fluorescent screen. As shown in the Figure, the indicator tube 10 is coupled to a valve 18, the anode 21 of which is connected to the anode 13 of the indicator. This is connected, in turn, to the control rod 15 which shadows the fluorescent screen 14. The cathode 11 of the indicator is tapped to a potentiometer 16, 17 so that it is above earth potential. With no signal on the grid 20, the current through the resistance 22 drops the voltage of the anodes 21, 13, and therefore the voltage of the rod 15, below that of the fluorescent screen, so that the shadow thrown by the rod is a maximum. The circuit constants are so chosen that the voltage-drop across the tube 18 is less than that across the resistance 17, so that the rod 15 is negative with respect to the cathode 11. This increases the normal area of the shadow it casts. The indicator tube may contain only the elements 11, 15, 14, the necessary amplification being effected either by the valve 18, or by a separate combined amplifier and detector.

Abstract: A water-resistant fireproofing agent comprises (a) a resin varnish as binder, and (b) a sparingly water-soluble salt of a basic amino compound and an acidic amino compound to form a layer of carbonaceous foam when heated.  Suitable basic amino compounds are melamine, cyanamide, dicyandiamide, alkyl- and aryl-amines.  Suitable acidic amino compounds are amino-carboxylic acids, sulphonamides, aminosulphonic acids and aminophosphonic acids; e.g. metanilic, sulphanilic or anthranilic acid.  The preferred salt is that of sulphanilic acid with melamine. Mixed salts may be used.  Preferred binders are butanolized melamine-alkyd resins in butanol; an acid catalysed butanolized melamine or urea-melamine resin; a melamine resin modified with alkyd and/or phenol resin; solutions or dispersions of melamine-formaldehyde resins.  The compositions may also include other resin varnishes, plasticizers, fungicides, insecticides, pigments, fillers, e.g. asbestos, conventional fire-inhibiting components, and carbonizable substances such as pentaerythritol or dextrin.  In Example (1) a suitable composition consists of butanolized melamine-alkyd resin solution in butanol, melamine-sulphanilic acid salt, titanium dioxide, pentaerythritol and conc.  HCl as hardener, (2) is similar but uses butanolized modified melamine-alkyd-phenol resin in butanol as the resin varnish; (3) uses a melamine-sulphamic acid salt, and (4) uses a melamine-anthranilic acid salt as well as a small quantity of tributyltin acetate as fungicide.  A comparation experiment is also described using the resin varnish of Example 1 together with a resin prepared from formaldehyde, melamine and phosphoric acid, both with and without an addition of melamine-sulphanilic acid salt.  Preparations are described of:  (a) a butanolized melamine-formaldehyde resin, (b) a butanolized melamine resin modified with a phthalic acid pentaerythritol polyester, (c) a butanolized melamine - phenol - formaldehyde resin and (d) a butanolized melamine-phenolformaldehyde resin modified with a phthalic acid-pentaerythritol polyester.

Abstract: 604,683. Thermally - actuated valves. CARRIER ENGINEERING CO., Ltd. May 26, 1945, No. 13218. Convention date, June 28, 1944. [Class 135] Means for controlling the flow of heating or cooling fluid, e.g. water, to an air attemperator comprises a valve housing 20 having a water outlet port 43 controlled by a valve 42 actuated by a lever 21 subject to the action of a pair of thermal systems, each constituted by a bellows and a bulb interconnected by a tube, the bulbs 35, 37 being located in the space to be attemperated and the bellows 29, 30 acting on the lever 21. The left-hand thermal system is filled with a fluid in the vaporized state, except for a small drop of liquid, whilst the right-hand system is filled with a similar fluid, but in the liquid state except for a small bubble of vapour. When heating fluid is supplied to the valve housing through an inlet 44, incorporating a filter 46, the bellows are heated to a temperature above that of the bulbs, whereby the drop of liquid in the left-hand system will be located in the bulb 35, whilst the bubble of vapour in the right-hand system will be situated in the bellows 30 and, since the vapour pressure will be dependent upon the temperature at the surface of the liquid, the bellows 30 will expand under the action of the heated fluid, against the action of a spring-loaded bellows 22 to open the valve, whilst the bellows 29 will expand and contract to vary the valve opening according to variations in the temperature of the bulb 35. When the device is used for cooling, cooled fluid is supplied which cools the bellows 29, 30 below the temperature of the bulbs 35, 37, whereupon the drop of liquid is formed in the bellows 29 and the bubble of vapour in the bulb 37 so that the bellows 29 contracts to open the valve and the bellows 30 expands and contracts in response to changes in the temperature of the bulb 37. The areas of the bellows 22, 29, 30 and the distances between the points at which the bellows act on the lever 21 are so arranged that operation of the valve is unaffected by variations in the pressure of the heating or cooling fluid.
