Abstract: 633,374. Reinforced concrete. TAUB, J. April 24, 1947, No. 11013. Convention date, April 29, 1946. [Class 20 (iv)]  Fresh iron or steel reinforcing bars are added to the original iron &c. bars of existing reinforced concrete structures by removing the concrete to lay bare some or all of the original reinforcing bars, arranging the added bars parallel and in spaced relation to the original bars over at least a portion of the length of either, interconnecting the bars by short iron or steel pieces inserted between and welded to the parallel stretches, and covering the original and added bars with concrete. The beam shown in Figs. 6 and 7 with normal reinforcements 2, 3 tied by stirrups 4 is strengthened by removing concrete to expose the bars 3 to which further bars 5 are connected by welding pieces 6 to both bars. The pieces 6 are preferably connected to one bar on the ground and to the other in situ. Short binders 7 may also be added, as shown in Fig. 7 or of the same height as the binders 4. Additional bars may be arranged laterally of the original bars, or bars 131, 15<SP>1</SP> may be connected by stirrups 18 in diagonal positions as in Fig. 11. Additional bars 23 and bars or angle irons 25 with stirrups 26 may be connected to the original bars 21 of aT-section beam by members 24, see Fig. 13. Fig. 15 shows bars 5<SP>1</SP>, added to the lower reinforcement, connected by binders 28 located outside the beam and welded to angle irons 29 which are laid on the upper edges of the beam and connected by strips 30. The original bars may be strengthened by connection to bars 15<SP>11</SP>, the binders 31 of which are welded to transverse irons 32 at the top as shown in Fig. 16. In Fig. 17 a cantilever beam 38 is added to a beam 33 by welding members 37 to the reinforcements of beam 33 and to bars 36 adding binders 39 and moulding the beam 38. When an existing reinforcement is strengthened or connected to another part, either the load is taken off the original reinforcement by propping, or the added reinforcement is prestressed to correspond to the stress of the original bars.

Title: Process for the catalytic destructive hydrogenation of carbonaceous materials
IPC: C10G1/04
Filed: 1937-04-20
Abstract: In the liquid-phase destructive hydrogenation of carbonaceous materials face from ash, e.g. de-ashed coal, tars, distillation or cracking residues, coal extracts, in which the unconverted material containing catalyst is re-cycled to the reaction, the coarse constituents of the used catalysts are removed from the re-cycle products, leaving the small finely-divided and still active catalyst particles therein, by sedimentation in a settling vessel followed by filtration or centrifuging.  An extract obtained from bituminous coal mixed with heavy oil obtained from a previous hydrogenation and with 5 per cent pulverized bog iron ore is hydrogenated at 480 DEG  C. under 650 atmos. pressure.  The gasoline and middle oil formed are withdrawn in vaporous state from a hot catchpot arranged behind the converter and the liquid products together with catalyst are withdrawn with reduction of pressure to a settling vessel heated by steam where they remain for 8 hours.  A thick sludge settles and is removed and freed from oil in a centrifuge.  The residue remaining in the centrifuge amounts to about one-fifth of the total catalyst employed and comprises sharp-edged grains of sand and a coarse-grained powder containing a large proportion of iron.  The centrifuged oil and the liquid withdrawn from the settling vessel are mixed and used as pasting agent, an amount of fresh catalyst corresponding to the quantity of solid residue separated being added to the paste. With a throughput of 0,6 kg. of extract per hour per litre of catalyst, 25 per cent of the extract is converted into gasoline and 55 per cent into middle oil.

Title: Improvements in or relating to methods of and means for growing crystals
IPC: C30B7/00
Filed: 1944-06-15
Abstract: <PICT:0640982/III/1> Crystals of materials, such as the primary phosphates of potassium and ammonium, which crystallize naturally in elongated prisms with end faces, are grown so as to have large transverse dimensions and moderate lengths by using a seed body of the crystalline material having at least one face disposed at an angle to a longitudinal crystallographic axis of symmetry equal to the angle between one of the end faces and the same axis in the natural crystal and parallel to the end face, and also having a thickness to length ratio that is large in comparison with the ratio of the natural rate of lateral crystal growth to the natural rate of longitudinal growth.  The seed bodies may be fabricated from an elongated crystal in a number of ways as indicated in Fig. 1 which shows a crystal of primary ammonium phosphate.  For example, the pyramidal ends 21 of the crystal may be cemented together to form a composite seed body (Fig. 2), care being taken that the bases of the two pyramids are perpendicular to the optic axis and equal in area, and that the positive and negative edges bear the same relation to each other that they do in a natural crystal.  The polarity of the edges is found experimentally by the application of pressure or by the action of a solvent, such as water, for a short period of time. A single end pyramid may also be used as a seed body, but in this case the base of the pyramid should be protected against the deposition of crystalline material thereon. Inclined sections 24, the major faces of which are parallel to one of the end faces, and prisms 28, 29, may also be used.  In order to grow crystals, the seed bodies are mounted in a tank containing a saturated solution of the crystalline material, and the temperature of the solution is then gradually lowered while the tank is rocked slowly from side to side to cause the solution to flow gently back and forth in the direction of the optic axis of the seed bodies.  Specification 640,999 is referred to.

Title: Improvements in compositions prepared from oil modified alkyd resins
IPC: C09D167/08
Filed: 1947-04-29
Abstract: A liquid composition suitable for use in coating, impregnating, and similar applications, comprises ethyl cellulose, an oil-modified tetrachlorphthalate alkyd resin, and a solvent. The ethyl cellulose preferably has an ethoxyl content of 46.8-49.5 per cent and a viscosity of 7-100 c.p., as determined at 25 DEG  C. on a 5 per cent concentration in a solvent composed of 4 parts of toluene and 1 part of denatured alcohol.  The proportions of ingredients may be varied from those in which the ethyl cellulose predominates to those in which the alkyd resin predominates.  The modifying oil employed in making the resin may be a drying, semi-drying, or non-drying oil.  It may be a fatty oil or a fatty oil acid derived from a vegetable or animal source or produced synthetically.  Part of the tetrachlorphthalic acid or anhydride may be replaced by another polybasic acid, e.g. phthalic, isophthalic, terephthalic, benzophenone-2,41-dicarboxylic, diphenic, naphthalic, oxalic, malonic, succinic, glutaric, adipic, suberic, or tricarballylic acid. The polyhydric alcohol used in making the resin may be ethylene, diethylene, dipropylene, or trimethylene glycol; glycerol, pentaerythritol, sorbitol, or mannitol.  The resin may also be modified by including a monohydric alcohol such as diethylene glycol mono-ethyl ether or ethylene glycol mono-ethyl ether in the mixture to be condensed.  The modifying oil may be raw, heated, or blown, linseed, rapeseed, cottonseed, chinawood, castor, soya bean, perilla, oiticica, babassu, palm, or fish oil, or it may be a fatty acid such as linoleic, linolenic, palmitic, oleic, stearic, or clupanodonic. In an example, glycerol, tetrachlorophthalic anhydride and coconut oil fatty acids are mixed together and heated in an atmosphere of nitrogen at 190-196 DEG  C. for 3 hours.  The temperature is then raised to 226 DEG  C. for 45 minutes.  The resin obtained is dissolved in xylene.  In another example, the resin is modified with linseed oil fatty acids, oleic acid, castor oil, and unchlorinated phthalic anhydride.  Other examples describe the production of ethyl cellulose coating compositions containing the modified alkyd resins. Other specified ingredients include butyl alcohol, xylene, dipentene, pine oil, tricresyl phosphate, petroleum solvents, natural resins, other synthetic resins, ketones, glycol diacetate, nitroparaffins, and chlorinated hydrocarbons. Pigments such as chrome yellow, brown iron oxide, and toluidine red, may be included in the compositions.

Title: Process for the production of metal coatings on chromium and chromium alloys
IPC: C25D5/40
Filed: 1933-04-24
Abstract: To obtain adherent metal coatings either electrolytically or by the fusion melting process on chromium or chromium-containing alloys, the surface of the chromium or chromium-containing alloy is exposed to agents having a strongly acid action during the application of the coating.  When the coating is applied electrolytically a strongly acid bath with a pH value less than 2,5 is used.  A thin deposit may be formed with such a bath and a further coating of the same or a different metal may then be applied using a weakly acid or alkaline plating bath.  Nickel, tin, zinc, and cadmium are specifically referred to as metals which can be applied as coatings on chromium-containing alloys such as rustless steels or on chromium surfaces such as chromium-plated articles.  A bath for plating with nickel consists of nickel sulphate, sodium sulphate, boric acid, and ammonium chloride, the bath being brought to the required acidity by the addition of sulphuric acid.  When coating by the fusion melting process, the acid action is obtained by the use of strongly acid fluxes such as concentrated hydrochloric acid.  The Specification as open to inspection under Sect. 91 describes the electrolytic coating, preferably with copper, of the bottom or the entire outer walls of a cooking or frying vessel made of rustless steel, in order to improve the heat conductivity and to prevent warping.  Two deposits of the same or different coating metals may be applied if desired.  This subject-matter does not appear in the Specification as accepted.

Filed: 1938-04-22
Abstract: 517,266. Treating textiles. SPALDING & BROS. (BRITISH), Ltd., A. G. April 22, 1938, No. 12112. Convention date, May 13, 1937. [Class 15 (ii)] [Also in Group XV] In the manufacture of tennis and other game balls having a fabric covering containing animal fibres, the tendency of the covering to become discoloured by contact with soil is decreased by treating the fabric with an-agent reacting therewith under suitable conditions of concentration of the agent and duration of the treatment. Specified reagents are hydrogen peroxide, sodium peroxide, chlorine water, potassium permanganate and alkali or ammonium hydroxides. A wetting agent, such as sodium lauryl sulphate or sodium hexadecyl sulphonate, may be used in conjunction with the reagent. Fabric suitably treated shows the pink, reddish violet or violet colour of the biuret test when treated in the cold with solutions of caustic alkali and copper sulphate. The fabric .which may be, for example, of wool, rabbit fur, alpaca, mohair or.camel hair, may be treated before or after its assembly upon the ball centre. Wool, so treated, has an increased affinity for acid and basic dyes. In an example, a tennis ball comprising a rubber compounded centre and a wool fabric cover, cemented under heat or adhered thereto, is thoroughly wetted in a 30 per cent. solution of hydrogen peroxide, the solution is drained off and the ball, preferably after immersion in a 5 per cent. solution of ammonium hydroxide, is dried at a temperature not above about 82‹ C. If, in place of the hydrogen peroxide solution, a saturated solution of chlorine in water, a 1 per cent. solution of potassium permanganate or a 10 per cent. solution of sodium peroxide is used, the resulting discoloration is removed by treatment with a weak solution of hydrogen peroxide.
