Title: Improvements in or relating to metallic coatings on iron and steel
IPC: C23C16/08
Filed: 1942-03-20
Abstract: 574,737. Coating metals ; cementation. SAMUEL, R. L. March 20, 1942, No. 3729. [Classes 72 and 82 (ii)] In the production of metallic coatings on iron or steel, the latter is heated to 5SO-1250‹ C. with an agent comprising a porous heat-resist. ing substance containing on its surface and in its pores a compact and adhesive layer containing a halide or halides of manganese, nickel, cobalt, copper, tin, niobium, tantalum, tungsten, molybdenum, vanadium, titanium and/or zirconium in an atmosphere of hydrogen or other gas, e.g. acetylene, which does not react with the iron &c. except by carburization or decarburization. Where the coating metal is nickel, cobalt, copper or tin, the agent is prepared by impregnating the porous substance with a solution of a halide, preferably a chloride, of the metal and when the other metals are used by impregnating the porous substance with, a solution of a highly soluble sodium potassium or ammonium salt of the metal and reducing it by heating with a hydrogen halide at an elevated temperature. The porous substance may consist of fragments of porcelain, ceramic, pottery, earthenware or slag. Coatings containing two or more of the above metals or one of the above metals with chromium may be made by producing porous substances containing mixtures of the halides of the metals concerned. If the heating takes place in an atmosphere of acetylene, part of the coating may be in the form of a carbide. Specifications 572,703 and 3077.5/38, as open to inspection under Sect. 91, are referred to.

Title: Improvements in or relating to circuit arrangements for charging a condenser
IPC: H05B41/32
Filed: 1950-02-14
Abstract: 676,465. Supply systems for space discharge lamps; condenser arrangements. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 14, 1950 [Feb. 17, 1949], No. 3759/50. Class 38 (iv). A condenser 1 from which energy is taken in an intermittent manner, e.g. for supplying a photo-flash discharge lamp, is charged to a predetermined voltage and then disconnected from the charging source, to economise in energy consumption, by means including a spark-gap 11 the current through which, when it breaks down, is utilized to interrupt the charging circuit. As shown, the condenser 1 is charged to a high voltage over converter 3 from a battery 5 when a push switch 4 is operated to energize coil 6 of a relay 7 to close retaining contact 8 and contact 9 included in circuit with the spark-gap, e.g. gas discharge tube 11. Upon the condenser attaining a predetermined voltage the discharge tube 11 breaks down and current flows through relay coil 10 to cause the contacts 8 and 9 to open and so interrupt the charging current and disconnect the discharge tube from the condenser. Sparking at contact 9 is reduced by including a resistance 12 in circuit and shunting the coil 10 and discharge tube 11 with a condenser 13. To vary the maximum voltage required across condenser 1 a further resistance 14 may be shunted across the tube 11 and coil 10 so as to form with resistance 12 a potential divided for the tube 11, either resistance being made adjustable.

Title: Improvements in and apparatus for the heating of liquids capable of being decomposed
IPC: C10G9/24
Filed: 1929-02-08
Abstract: 333,241. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Feb. 8, 1929. Hydrocarbons,cracking; bulk evaporators.- In apparatus having moving heating- surfaces for heating liquids capable of decomposition and applied particularly to the cracking. of oils and the concentration of solutions, dispersions or emulsions of easily decomposable substances such as gelatine, the heating surfaces are made stream-line in cross -section and so arranged and disposed that their movement meets with the least possible resistance. In one form, the bodies are constructed of short strips, completely immersed and arranged to rotate round a central axis. the length of the strips being parallel to the axis of rotation and their breadth in a direction tangential to the circular path of the heating body; preferably the bodies are electrically heated. Stirrers or pumps may be provided to move the liquid in a direction opposite to that of the stirrers. As shown in Fig. 1, in a vessel 1 wherein hydrocarbons of high boiling point are cracked, a rotary heating body 2 is immersed in the liquid and carried by a hollow shaft 2<a> mounted in bearings 4, 5 and passing through a stuffing-box 6 on a dome 21. Supported from the frame of the heating body are chrome-nickel strips 2<b> connected to terminals 10 of conducting strips 9 enclosed in the shaft 2<a>., the strips being arranged in parallel or series, or in groups and insulated from the supporting-frame. Means are. provided for reversing the shaft 2<a>. Fresh liquid is inserted at the pipe 12 and cracked products escape at an outlet 13 in the dome. Accumulation of carbonaceous and pitchy deposits is prevented by the regular removal, from the lower part of the vessel, of part of the contents through a pipe 14 by a pump 16 and a pipe 15. Where floating carbon is produced, this is removed from the surface. An indication of the level of the liquid is obtained by means of pipes 17, 18 through which small currents of a suitable gas, e.g. nitrogen, are passed, the difference in pressure being indicated and recorded in known manner. As shown in Fig 2, the heating strips 2<b> are made of streamline form and arranged so that the axes of symmetry are tangential to the path of the heating body. In a modified form of apparatus for the concentration of readily decomposable substances by evaporation in vacuo, the heating body is arranged as a double coil of stream-line cross section through which heating fluid is passed, a co-axially situated stirrer being provided within the inner coil. Examples of the cracking of oils and the distillation of a gelatine solution are given.

Filed: 1963-02-01
Abstract: 957,035. Centrifugal pumps. M. L. EDWARDS. Feb. 1, 1963, No. 4286/63. Heading F1C. In a vapour or gas separating pump 12, for example an aircraft fuel booster pump, comprising a pumping chamber containing an impeller 17 having an axial inlet eye in axially aligned communication with the pump inlet 30 and a number of openings 40 extending through the wall 28 of the pumping chamber around the inlet end of the impeller, each of the openings 40 is formed with opposite wall surfaces 41, 42 which diverge outwardly from the inside surface of the pumping chamber approximately tangentially to the impeller 17 and intersect the inside surface of the pumping chamber at acute angles forming sharp edges 44 to facilitate gas flow out of the chamber during low main flow rates and liquid flow into the chamber during high main flow rates. The flow reversal through openings 40 occurs since, during low main flow rates, the impeller 17 imparts sufficient rotary motion to the incoming liquid to expel a substantial quantity thereof together with any gas through openings 40, whereas, during high main flow rates, the predominantly axial motion of the main flow instead entrains liquid into the pumping chamber through the openings 40. The openings 40 are preferably circular in which case the walls 41, 42 are opposite sides of a frusto-conical wall. The walls 41, 42 may extend to the outer surface of the pumping chamber wall 28. The pump 12 has a number of legs 18 connected with a flange 19 secured to the bottom of an aircraft fuel tank 10 by screws 20 engaging an oval mounting ring 21.

Abstract: 764,570. Filters. FRAM CORPORATION. Feb. 14, 1955 [March 10, 1954], No. 4310/55. Class 46. [Also in Group XXXIV] Oil to be filtered enters at 18 a recess 19 in a casting 17 closed by an apertured plate 20, and passes through an aperture 21 in the latter to the outside of a part-flow filter element 37. Some of it passes through a longitudinally-pleated paper annulus 38 and a corrugated perforated core 42 but is prevented from passing through perforations 32 in a centre tube 13 by an imperforate tube 50. It passes instead through holes 45 in a centering ring 44 and then through grommets 46 to a hole 29 in a nut 25 and a hole 30 in the casting 17 to the crankcase. The remainder of the oil flows through a by-pass valve 35 into the centre tube 13 and thence through passage 31 to the bearings. The partflow cartridge may be replaced by a full-flow cartridge (not shown) which is not provided with either the imperforate tube 50 or the grommets 46, and its centering rings 44 are imperforate. Also the paper of which it is composed has a much greater porosity. Flow is then radially inwards direct to the centre tube 13 and along passage 31 to the bearings. The valve 35 serves in this case as an excess pressure relief valve.

Title: Ion exchange resin indicator compounds
IPC: B01J39/04
Filed: 1951-02-26
Abstract: A non-toxic ion-exchange resin indicator compound, for determining whether the pH of gastric juice in a stomach is above or below a predetermined value, comprises an ion-exchange complex synthetic polymer resin having associated therewith 0.04-0.5 millimoles of displaceable and readily identifiable ions per dose, the amount of indicator ion per gram of ion-exchange resin being less than the total capacity of the resin.  The dose is administered orally and if the hydrochloric acid concentration is above a certain value, the ions are displaced and appear in body fluids, for example, urine, blood, saliva or sweat.  The concentration of ion in the resin varies depending on the size of the dose, which may be from 1-50 grams. Suitable cation or anion exchange resins are those available under the Registered Trade Marks "Amberlite" and "Permutit."  The displaceable ions may be cations or anions; in examples, indicator compounds are prepared by treating resins with (1) quinine hydrochloride; (2) tetramethylaminophenothiazinium chloride (methylene blue); (3) 2, 4-diamino-41-ethoxyazobenzene monohydrochloride (serenium); (4) sodium fluorescein (uranin); (5) potassium iodide or potassium thiocyanate.  Tests are described in which the indicator compounds are mixed with solutions of hydrochloric acid and gastric juice of varying pH values.
