Patent GB-207830-A (GB)
IPC: C01C3/02
Filed: 1923-12-03
Abstract: A catalytic agent for use in obtaining hydrocyanic acid by the reaction of a gaseous nitrogen compound such as ammonia with a gaseous carbon compound such as carbon monoxide comprises activated carbon, which may be used alone or as a coating upon inert carriers or in admixture with other catalysts such as metals or metallic oxides, or may be precipitated upon pumice.  The oxides preferred are those which are not reducible or are reducible with difficulty.  The Specification as open to inspection under Sect. 91 (3) (a) includes the case of other highly adsorbent substances instead of activated carbon, and states that the oxides or metals may be used alone or may be supported upon activated carbon, asbestos, or wood charcoal.  Iron oxide or the like, may be used if protected from oxidation by admixture with other substances such as alkali or alkaline earth oxides or alumina.  When the reaction is affected under pressure, the products of reaction are quickly cooled, for instance, by releasing the pressure and applying external cooling. This subject-matter does not appear in the Specification as accepted.ALSO:Hydrocyanic acid is obtained by the reaction of a gaseous nitrogen compound such as ammonia with a gaseous carbon compound such as carbon monoxide in presence of activated carbon, which may be used alone or as coatings upon inert carriers or in admixture with other catalysts such as metals or metallic oxides, which may be precipitated upon pumice.

Operation. To inject the catheter into a patient the outer enclosure 24 and needle cover 20 are first removed. After insertion of the end of the needle 6b through the skin 25 into a vein 27 a depression of the plunger 6c will pressurize the solution 18 to force the solution around the catheter in the needle 6b and will cause a length of the catheter to be propelled from the body 6a. The needle is withdrawn from the patient and the catheter is removed from the needle to permit the catheter to be attached to a source of an infusion liquid by means of the infusion liquid-receiving connector 22. If less than the full length of the catheter is required in the patient, the catheter may be withdrawn accordingly by counting the number of index marks 13 on the catheter as the latter is introduced into the patient. Further embodiments are described and include a device with a tapered barrel (58a) and a depressible end-cap (58c) (Figs. 13-16 not shown), a device with an enclosure (74) and pleated section (80) (Figs. 17-22 not shown), a packaged device (Figs. 23-26 not shown), and a device which may be packaged and includes an assembly (166) for containing the catheter (Figs. 27-34 not shown).

Patent GB-910975-A (GB)
Title: Means for checking electrical measuring feelers
Filed: 1960-09-09
Abstract: 910,975. Measuring electrically. PERTHEN, J. Sept. 9, 1960 [Sept. 11, 1959], No. 31130/60. Class 40 (1). A linear dimension gauge, in which movements of the feeler 2 vary inductances 7, 8, is calibrated with the aid of stops 11, 12 for limiting the maximum movement of the feeler to an accurately predetermined distance, or with the aid of a single adjustable stop (Fig. 2, not shown) limiting the outward movement of the feeler. If a prescribed deflection is not reached in an indicator 30, the amplification may be increased. The amplifier has a voltage divider 23 to 27 for adjusting the range of measurement, and a voltage divider 28 for varying the overall amplification. The latter may also be varied by adjusting resistance 22. On removal of workpiece 18 the feeler drops and pin 10 rests on jaw 12. If the feeler is then raised by hand, or by energizing coil 17 to attract armature 16, pin 10 will come up against jaw 11 and the indicator will give a corresponding reading. For automatic operation only one stop member need be provided (Fig. 2, not shown) and the pin drops from a specified upper position to an adjustable abutment to provide the standard length. If this is much greater than the lengths normally measured, e.g. when determining surface roughness, an additional resistance may be connected in series or parallel with the range-adjusting voltage divider during the checking operation, or resistances, inductances or capacitances may be connected in parallel with the measuring bridge. The device may be arranged to operate automatically and give a warning signal and block subsequent readings if the prescribed check deflection is not reached. Instead of an inductive transducer a capacitative, piezo-electric or ohmic type may be used.

Abstract: 136,568. Gillet et Fils, (Assignees of Schwartz, C.). Dec. 13, 1918, [Convention date]. Inkless printing by chemical reaction; resist printing; printing with special materials.-Fabrics composed of vegetable fibres are treated to impart to them the character of wool by impregnation with a solution of cellulose of any origin in nitric acid, preferably at a concentration of not less than 65 per cent, and by washing the treated fibres with water to precipitate upon them slightly nitrated cellulose. Parts only of the fabrics may be treated either by printing with the cellulose solution at the desired parts, or by printing with a resist, such as kaolin, at the parts not to be treated and subsequent impregnation with the cellulose solution, the precipitation being produced by washing in each case. Treated fibres may be denitrated to increase the wool-like effect. The treatment is preferably effected at a temperature of 12 to 30‹ C., but the reaction takes place at 0‹ C.. the solution being more viscous however. The cellulose used in making the solution may be wood pulp or cotton waste, mercerized or not. Three examples of solution for treating fabrics of American cotton and one example for fabrics of Egyptian cotton are given.
Patent GB-609225-A (GB)
Title: Improvements in or relating to vinyl halides and method of preparing same
IPC: C07C17/08
Filed: 1945-11-20
Abstract: Vinyl halides are produced by the catalytic reaction of acetylene with a hydrogen halide in the vapour phase by passing a gaseous mixture containing acetylene and sufficient hydrogen halide to react with all the acetylene through at least three catalyst containing reaction chambers, arranged in series, until the per cent overall conversion has dropped to a predetermined level, changing the point of introduction of the reactants into the series of chambers from the first chamber to one later in the series, introducing additional reaction chambers containing fresh catalyst at the end of the series to make the total number of chambers at least three, and continuing the flow of reactants through the new series.  The flow of reactants may be continued through the new series until the per cent conversion has again dropped to a predetermined level and the process may then be repeated.  The process is described with reference to the production of vinyl chloride by reaction of acetylene with hydrogen chloride, the catalyst being a complex salt of mercuric chloride and potassium chloride (HgCl2.3KCl) deposited on activated charcoal. Three catalyst-containing chambers are used and when the overall conversion is 95 per cent, the first chamber is removed and a new chamber containing fresh catalyst of the same kind is added at the end of the series.  Other catalysts which may be used are metal halide and other catalysts known to be effective in the reaction, antimony trichloride, bismuth trichloride and mercury being specified.  The invention may also be applied to the production of vinyl bromide and vinyl fluoride.
