Patent GB-706832-A (GB)
Title: A process for producing glass filaments coated with resinous material and the resulting coated filaments
IPC: C03C25/26
Filed: 1952-07-31
Abstract: Glass filaments are coated with a glycidyl ether of a polyhydric phenol or a polyhydric alcohol which has a 1, 2 epoxy equivalency between 1 and 2, the coating being applied immediately after the filaments have been formed by drawing and then hardened. The glycidyl ethers have the formula: <FORM:0706832/IV(c)/1> where n is O or an integer and R is the divalent radical of the dihydric alcohol or dihydric phenol.  The ether is a mixture of compounds which have different values of n and contains a small amount of material with one or both of the terminal glycidyl radicals in hydrated form.  The term "epoxy equivalency" means the average number of 1, 2 epoxy groups <FORM:0706832/IV(c)/2> contained in the average molecule. Polyhydric phenols which may be used in the preparation of the ether include resorcinol, catechol, hydroquinone, methyl resorcinol, 2, 2-bis (4-hydroxyphenyl) propane, 4, 4\sv dihydroxybenzophenone, bis (4-hydroxyphenyl) methane, 1, 1-bis (4-hydroxyphenyl) ethane, 1, 1-bis (4-hydroxyphenyl) isobutane, 2, 2-bis (4-hydroxyphenyl) butane, 2, 2-bis (4-hydroxy-2 methyl-phenyl) propane, 2, 2-bis (4-hydroxy-2 tertiary butylphenyl) propane, 2, 2-bis (2-hydroxy-naphthyl) pentane and 1, 5 dihydroxynaphthalene.  The ethers have a melting point above 50 DEG C. and may be applied as a melt by small heated rollers in solution with chloroform, carbon tetrachloride, ethylene dichloride or trichloropropane.  A hardening agent which may be p-toluenesulphonic acid, benzenedisulphonic acid, ethanesulphonic acid, methanedisulphonic acid, phosphoric acid, butyl hydrogen phosphate, BF3-ether complexes, trimethylamine, ethylene diamine, diethylene triamine, diethylamine or piperidine is applied to the coated filament immediately after the application of the ether.  The hardening may be promoted by a blast of heated air and the coated filaments may be arranged in parallel relationship to form strands. The coating diminishes the tendency of the glass filaments or strands to abrade each other.

Abstract: 901,989. Sealing electric lamp bulbs. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 18, 1961 [June 1, 1960], No. 19423/60. Class 39 (2). [Also in Group XXIII] In a method of filling with gas and sealing the envelope of electric lamps, a vitreous tube is inserted within the exhaust opening of the envelope, gas is passed through the tube so as to displace the air and the tube and envelope are heated and deformed so as to close both the tube and the envelope. The bulb may be of the type in which the sealed neck is shaped to constitute a projecting stem for supporting the envelope in a suitable holder. A spherical bulb 1 having an extending neck 5 is supported with the neck pointing downwards, a filament 2 supported by lead-in wires 3 separated by a bead 4 is inserted through the neck and a tube 6<SP>1</SP> is inserted in the opening to lie between the leads 3. Gas, e.g. argon, is passed in through the tube 6<SP>1</SP> and the air escapes through the annular passage between the neck 5 and tube 6<SP>1</SP>. The neck 5 is then heated in the vicinity of the tube 6<SP>1</SP> and both the neck and the tube are closed by the application of pinching jaws 8, the flow of gas being maintained during sealing. The jaws 8 are shaped to produce a stem portion of the desired shape. As applied to a lamp having an inwardly-directed stem terminating in a pinch through which the lead-in wires are sealed, the exhaust tube is formed in the stem and the filling tube inserted therein, sealing taking place as close as possible to the base of the envelope. During sealing, the envelope may be drawn slightly away from the lower ends of the exhaust and filling tubes which are suitably held.

Patent GB-600328-A (GB)
Title: Corrosion inhibition and anti-corrosion packaging
IPC: C23F11/02
Filed: 1945-07-30
Abstract: Volatile compounds having a nitrite ion which are used as water-corrosion inhibitors are composed mainly of organic nitrogen base nitrites particularly the salts thereof having a vapour pressure in excess of 0.0002 mm. Hg at 21 DEG  C., and preferably in excess of 0.001 mm.  The organic bases may be primary, secondary and tertiary amines, and quaternary ammonium bases, including pyridium bases, which have basic diisociation constants close to that of nitrous acid which equals 4 X 10-4 at 18 DEG  C. Numerous examples are given of suitable bases.  The salts are prepared in most cases by stoichiometric reaction of an organic base with nitrous acid.  As examples: (a) the hydrochloride of the base is mixed with sodium nitrite dissolved in a liquid in which the inhibitor salt formed by double decomposition is insoluble; (b) hydrogen chloride gas is passed through an acetone solution of the base, and silver nitrite is added to form an acetone solution of the solution of the nitrite of the base and insoluble silver chloride, the nitrite being purified by recrystallization; (c) concentrated H2SO4 is added slowly to 50 per cent by volume aqueous solution of acetone in the presence of the nitrogen base and in excess of sodium nitrite.  The salt is purified after filtration; (d) an aqueous solution of the base is acted upon by the stoichiometric amount of H2SO4, and thereafter adding a stoichiometric amount of sodium nitrite.  The sodium sulphate is precipitated out by adding 2 to 5 volumes of acetone, and the nitrite purified.  The Specification contains a list of nitrites prepared by the above methods and gives their vapour pressures at 21 DEG  C. Dialkyl amine nitrite, oxazine nitrite, and morpholine nitrite are specifically claimed.  Other bases for preparing nitrites to act as inhibitors are the isologs of ammonium which have the general formula RXHy, where R is an organic radical which may be alkyl, cycloalkyl, aryl, alkaryl, or heterocyclic.  X is an element selected from phosphorous, arsenic, antimony, carbon, oxygen, sulphur, selenium, tin and iodine, and y is an integer from 2 to 4 depending on the valency of X. Trimethylsulfonium nitrite is an example of this series.  Also organic esters of nitrous acid having the general formula R-O-NO, and thionitrites R-S-O-NO, where R is an organic radical, may be used.  The manner in which the nitrites are used is described in the abridgment for Group XVII.  Specification 20340/47, as open to inspection under Sect. 91, is referred to.

Abstract: 943,065. Box making machines. AHLEN & AKERLUND FORPACKNING A.B. May 22, 1962 [June 15, 1961], No. 19567/62. Heading B5D. [Also in Division B8] Apparatus for folding up box blanks, having a central base portion 1 and side walls 2, 4 hinged thereto, one pair of opposite walls 4 including extensions 5 which fold over to enclose extensions 3 of the other pair of walls 2, comprises a plunger 33, a die bounded by guides 8-10 and a mechanism, operated by the return movement of the plunger 33 from the die, to fold the extensions 5. This mechanism consists of, for each end of the box, an axle 11 mounted in the guides 8 and carrying two curved arms 15 and a cam 16 which engages a cam 19 on a second axle 13. The axles 11 are connected by means of a chain 21 and a bellcrank 22, 24 to a roller 25 which rests of the plunger 33. When the plunger descends the roller 25 descends also, thus causing the axles 11 to rotate and hence raise the arms 15 outside the path of the plunger 33. Lugs 17 provided on the axles 13 include supporting members 18 which hold the box within the die. When the plunger 33 is raised the axles 11 rotate in the opposite direction so that the arms 15 fold the extensions 5 inwardly to enclose the extensions 3. The engaging cams 16, 19 then cause the axles 13 to rotate and thus turn the lugs 17 so that the box may be pushed through the bottom of the die as the next blank is being erected. Tabs 7 are forced up from the base 1 of the box by the members 18 to abut the flaps 6 adjoining the extensions 5.

Title: Improvements in or relating to valves for controlling the flow of liquids
Inventor: FRASER JOHN
IPC: F16K21/20
Filed: 1952-08-07
Abstract: 722,944. Fluid-pressure servomotor-control systems. AVERY-HARDOLL, Ltd. July 29, 1953 [Aug. 7, 1952; July 6, 1953], Nos. 19945/52 and 18708/53. Class 135. In a device for controlling the filling of tanks &c. in which an inlet valve is kept open by liquid flowing into the tank and is closed by resilient means and by pressure in a control chamber supplied with liquid from the upstream side of the valve, the escape of liquid from the control chamber being controlled by auxiliary valve means responsive to the level of liquid in the tank, the auxiliary valve means is operated in two stages, and the closing movement of the inlet valve following the first stage also reduces the rate at which liquid enters the control chamber. In an embodiment, an elbow 13 is secured to the bottom of a tank 11 and the flow of liquid into or out of the tank through the elbow is controlled by a valve 21. The valve carries a piston-like extension 22 which slides in a control chamber 24 in a housing 16 secured to the bottom of the tank. Liquid flowing in through the elbow 13 forces open the valve and flows into the tank through apertures 15 in the housing. In opening, the valve rides up a hollow stem 25 to uncover ports 31, 32 therein so that liquid can also flow into the control chamber through the ports 31, 32, the stem, and further ports 30 in the stem. While the tank is filling, the liquid entering the control chamber flows out again into the tank past valves 33A, 33B, venturis 41, and ports 44. In flowing through the venturis, the liquid entrains air from the space above the surface of the liquid in the tank through hoods 47, 48 depending inside the tank, tubes 45, 46, and apertures 43 at the throats of the venturis. The tubes 47, 48 also communicate with spaces 39A, 39B above pistons or diaphragms 38A, 38B secured to the stems of valves 33A, 33B. When the level of liquid in the tank reaches the lower end of hood 48, the flow of air through pipe 46 is cut off and the resulting depression applied to space 39B causes piston 38B to rise and valve 33B to close. The resulting restriction in flow of liquid through the control chamber causes a slight rise of pressure therein, which rise of pressure, with the help of the loading spring 23, partially closes valve 21 until port 32 is covered and liquid can flow into the control chamber only through port 31. As soon as the level of liquid in the tank reaches the lower end of hood 47, valve 33A will be closed in the same way to shut off all flow out of the control chamber. Pressure will now build up in the latter sufficiently to close valve 21 completely. To empty the tank, stem 25 is lifted by means of a handle 54 until a projection 55 on the stem contacts and so lifts the valve. In a modification, the two auxiliary valves 33A, 33B are replaced by a single valve, the stem of which acts, at its upper end, as a valve to change-over control from tube 46 to tube 45 when the level of liquid in the tank reaches hood 48.
