[Class 39 (i)] A vapour - filled discharge tube is surrounded by an exhausted envelope and comprises at least two parallel tube portions, the tube being supported from the envelope by means of a resilient member which holds the tube at at least one point of those sides of the tube portions which face one another. In the form shown, a U-shaped tube 1 is enclosed in an evacuated envelope 6 which is provided with an internal screen 8. The tube is supported from this screen by a helical spring 9 which is held in the constricted bend of the tube, with interposition of a mica strip 10. To ensure a tight grip by the spring 9, this is made slightly longer than required, so that it is compressed when in position ; or the spring may be twisted during insertion. A glass bead may also be used to secure the spring to the tube. More than one resilient support may be used, for example a second helical spring may be inserted between the ends of the tube. Tubes with three or four limbs may be supported similarly. A filling of neon, at 10 mms. pressure, and sodium is employed.

Title: Improvements in or relating to gauges for testing elongated objects for taper
IPC: G01B5/24
Filed: 1960-06-13
Abstract: 950,320. Measuring angles. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 13,1960 [June 16, 1959], No. 20686/60. Heading G1X. A gauge for determining whether an object e.g. a tube 19, Fig. 1, has a taper exceeding a maximum value, comprises two carriers 3, 10, each having a pair of pins 1, 2 and 6, 7, respectively for contacting the tube 19 at points spaced apart along its length, carrier 3 being slidable transversely to the axis of tube 19 in a fixed frame 5, whilst carrier 10 can pivot about an axis 11 lying between pins 6, 7, and extending perpendicularly to the-plane of pins 1, 2, 6, 7. The carrier 10 has a pair of abutments 8, 9 engageable with adjustable abutments 12, 13, the latter being initially set in accordance with the maximum permissible taper. On placing tube 19 on a pair of supports 14,15 and sliding carrier 3 to the left, tube 19 is held between pins 2, 7 and 1, 6, if the taper is not excessive, but if it is, then tube 19 is held at one end only because abutments 12, 13, prevent pivoting of carrier 10 beyond a certain angle. Accordingly if supports 14, 15, are now pivoted downwardly away from engagement with tube 19 and plates 35-38 moved to the position shown for plates 37, 38 in Fig. 4, one end of tube 19 will fall between plates 35, 36 or 37, 38, and this is arranged to prevent movement of the other plates, if the taper is excessive, but the tube 19 is held by pins 2, 7, and 1, 6, if it is not. On allowing plates 35-38 to move together in pairs and sliding carrier 3 to the right, the tube 19 rolls away to the right down the inclined plane formed by the plates if the taper is not excessive whereas if it is, it rests between the pairs of plates and on sliding them apart again the tube 19 falls vertically. In a.modification carrier 3 may pivot through a limited angle as well as slide.

Abstract: 1464438 Carriers for bottles, cans, &c ILLINOIS TOOL WORKS Inc 10 May 1974 [14 May 1973] 20840/74 Heading B8C A carrier 10 for a plurality of articles 17, Fig. 4, comprises a plurality of adjacently-disposed annular sections 12, 14, 16 of tough, resilient, flexible material each having an upstanding wall having a height greater than its thickness and having upper and lower margins which are of substantially equal circumference in the unstretched condition of the section, and junction elements 18, 20 joining adjacent sections to each other along segments of their adjacent margins; the plurality of annular sections including at least an intermediate section and additional sections adjacent thereto and the junction elements including a first junction element 18 joining the upper margin of the intermediate section to one of the adjacent sections and a second junction element 20 joining the lower margin of the intermediate section to another of the adjacent sections. A method of forming a carrier 10 comprises providing a thin-walled tube of tough, resilient, flexible material, Fig. 1, and alternately transversely slitting, the tube from opposite sides partially across the tube along generally parallel lines 32, 34 spaced axially of the tube. After the flattened tube, made, e.g. of low-density polyethylene has been slit, as shown in Fig. 1, the junctions 18, 20 being formed with slits for easy folding as desired, the tube is extended axially to form the interconnected sections 12, 14, 16, Fig. 3, which can each be stretched up to about 25% of ther original circumference and which, when the stretching force is released, can grip and readily conform to an article to which it is applied. A stepped arrangement of sections, Fig. 5, can be obtained by turning the original sections 12, 16 inside out in relation to the intermediate section 14. The tube can either be seamless or, formed by heat-sealing the margins of sheet material, and the slits 32, 34 can be formed by passing the tube between rollers carrying cutting knives. To prevent elongation of the slits the junctions 18, 20 may be 'coined'. Two tubes, each identical to the tube, Fig. 1, are joined as at (40), Fig. 7, not shown, to provide two rows of elements (12a, 14a, 16a) and (12b, 14b, 16b), Fig. 8, not shown. Opposite narrow areas of a large single tube can be welded together to provide two interconnected tubes which can be slit. Carriers, Figs. 3, 5, and Fig. 8, not shown, may be formed by deforming flat thermoplastic sheet material or, by injection moulding of a plastics material.

Filed: 1931-07-21
Abstract: 382,297. Screw propellers. MELCHER, F., 146, Gentzgasse, Vienna. July 21, 1931, No. 20861. [Class 114.] In oppositely running twin or multiple propellers a, b the local pitch angles of the pressure sides of the alternatively right- and left-hand propellers are chosen that they are greater by a constant angle of incidence than the corresponding angles which correspond to the tangent function of the ratio of the local speed of admission divided by the corresponding circumferential speed. The speed of admission of the element which is foremost in the direction of travel, is equivalent to the speed of the craft less the local wake and that if all the other successive elements is equivalent to the product of the effective outlet pitch by the number of revolutions per time unit of the adjacent front element. In setting out the propellers the relative entry and discharge speeds of the medium for both for and aft propellers is calculated point for point. After plotting the radius vectors of the relative entry and discharge speeds the pitches of the propeller can be calculated. The propellers are further characterized in that their clearance g is about 5 per cent of their diameter and the diameter of the rear propellers is diminished to conform to the contracted flow line conditioned by the forward propeller.

Title: A process for preparing copper-containing cellulose solutions with employment of dilute aqueous ammonia
IPC: C08B1/00
Filed: 1935-07-23
Abstract: Cellulose solutions are obtained by saturating cellulose with a solution of a cuprammine salt, prepared by treating a copper salt with an excess of ammonia of concentration of at most 8 per cent, and adding an alkali hydroxide in amount approximately equivalent to the copper salt used.  The ammonia may be replaced by an equivalent amount of an aliphatic amine or diamine.  In a modification solid cuprammine salts are mixed with cellulose in the ratio of about 2 mols. to 1 mol. and the mixture treated with an aqueous or aqueous ammoniacal solution of alkali hydroxide in amount equivalent to the anion of the copper salt.  Again, cellulose may be saturated with alkali hydroxide, which may contain a few per cent of ammonia, and cuprammine salt added, the proportions of cellulose, cuprammine salt, and alkali preferably being in the molecular ratio 1 : 2 : 4.  In a further modification, solutions of cuprammine salts prepared with excess of 3 to 8 per cent ammonia are first treated with about as much alkali hydroxide as is equivalent to the acid of the copper salt, and cellulose is introduced before the solution deposits copper hydroxide in the proportion of about one mol. to two mols. of cuprammine salt.  The following examples are given: (1) Linters are dispersed in a solution of copper sulphate or copper acetate in 5 per cent ammonia and sodium hydroxide is added to the mixture.  (2) Linters are distributed in a solution of cupric chloride in 5 per cent ammonia and sodium hydroxide is added.  (3) Cellulose is impregnated with a solution of copper chloride or copper sulphate in 4--6 per cent ammonia.  To this mixture sodium hydroxide is added. (4) Cellulose is introduced into a solution of copper chloride in 3 per cent of ammonia at 0 DEG  C. and sodium hydroxide is added.  (5) Sodium hydroxide is added to a solution of copper sulphate in 5 per cent ammonia, and cellulose is added as soon as possible with cooling and stirring.  (6) Cellulose is impregnated with a solution of commercial copper carbonate dissolved in 5 per cent ammonia and to the mixture sodium hydroxide is added.  (7) Cellulose is impregnated with a solution of cuprammine sulphate in very dilute ammonia and sodium hydroxide is added.  (8) Cellulose is mixed with a solution of cuprammine chloride, and a solution of sodium hydroxide in dilute ammonia is p  added.  (9) Cellulose is impregnated with a solution of caustic soda in 1--4 per cent ammonia, and to the mixture cuprammine chloride is added.  (10) Cellulose is impregnated with a solution of copper chloride in 6.4 per cent methylamine.  Sodium hydroxide is then added to the mixture.  (11) Sodium hydroxide is added to a mixture of cellulose and a solution of cupric chloride in 3 per cent ethylene diamine.  The solutions may be used in the manufacture of filaments, foils, films, and the like.
