Title: Improvements in thermostatic expansion valves
Inventor: MCGOWAN ERIC
IPC: F16K31/68
Filed: 1965-02-05
Abstract: 1,070,093. Valves. BRITISH THERMOSTAT CO. Ltd. Jan. 28, 1966 [Feb. 5, 1965], No. 5115/65. Heading F2V. A thermally-responsive pressure element (25, Fig. 1, not shown) at the outlet of a refrigerator evaporator (9) is connected to a chamber 24, Fig. 2, bounded by a diaphragm 22 which is attached to a movable closure member 15 controlling flow between the outlet of a condenser (3, Fig. 1) and the evaporator inlet. The closure member 15, Fig. 2, has a spherical part which is supported upon a complementary surface of a spring-loaded hollow element 17 to provide limited universal movement therebetween and hence accurate co-operation of the member 15 with its seal 14. An expansible metal sealing bellows 31 surrounds the valve stem 21 and is filled with refrigerant from the inlet 5 via a clearance 30 between the stem 21 and a neck 29. The diaphragm 22 is biased against movement by a spring 32, one end of which abuts a hollow piston 33 the position of which and hence the spring-loading being adjustable. The chambers 27 beneath the diaphragm 22 may be connected either to the evaporator or the valve outlet depending upon whether the pressure drop across evaporator is high or low. Since movement of the valve stem causes contraction or expansion of the bellows 31 the resulting flow of refrigerant through the clearance 30 results in damping of the action of the stem and closure member.

Title: Improvements in submarines
IPC: B63G8/04
Filed: 1924-02-28
Abstract: 212,541. Cantiere Navale Ansaldo San Giorgio, (Assignees of Feo, V. de). March 7, 1923, [Convention date]. Submarine vessels. - The non-resistant shell L which surrounds the resistant turret A and is contoured to minimize the propelling resistance of the submarine when submerged is adapted to be used as a steering-house during surface navigations and as a water ballast tank when submerged. This end is achieved by connecting the pipes S with a supply of compressed air which when supplied to the chamber expels the water therein through the openings D communicating with the water of flotation. When the chamber is to be used as a ballast tank, the compressed air is allowed to escape by way of the door C controlled from within, the hull by the shaft E. Glass windows I are provided tofacilitate steering operations.

Title: An improved process for sealing wires into vitreous envelopes
IPC: H01J9/32
Filed: 1931-02-19
Abstract: 369,349. Electric discharge tubes. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and EDEN, C. G., of General Electric Co., Wembley, Middlesex. Feb. 19, 1931, No. 5234. [Class 39 (i).] For sealing the leading-in wires in the manufacture of electric discharge tubes and other electrical apparatus with vitreous envelopes, a vitreous sealing body carrying an exhaust tube is presented to the open end of the vitreous vessel and the two are softened by heat and pressed together around the leading-in wires by pressure applied between the exterior of the vessel and some part of the sealing body other than the interior of the exhaust tube. In the construction shown the leading-in wires 2 are placed between the open end of the vitreous vessel 1 and the turned-over flange 4 formed on the flared end of the exhaust tube 3. The end of the vessel 1 and the edge 4 are then heated and pressed together to form a pinch, for which purpose a tubular mandrel 7 is brought into the groove 5 between the tube 3 and the flange 4 and a collapsable ring 6 is contracted against the outside of the vessel 1. Alternatively the tube 3, mandrel 7, and vessel 1 may be rotated while a roller is pressed against the outside of the vessel.

Patent GB-965380-A (GB)
Title: Production of sulphamic acid
IPC: C01B21/096
Filed: 1963-02-11
Abstract: Sulphamic acid is produced by reacting together urea, sulphuric acid and sulphur trioxide, or urea bisulphate and sulphur trioxide, in the presence of liquid sulphur dioxide as reaction medium, at a temperature of 55 to 110 DEG  C., and under superatmospheric pressure, e.g. at least 7 kg./cm.2 gauge, preferably 7 to 42 kg./cm.2 gauge.  In a preferred process oleum is added gradually, with agitation, to a mixture of urea and liquid sulphur dioxide for 1 to 20 minutes, preferably 5 to 8 minutes, and the temperature is maintained at 80-90 DEG  C. The temperature is then raised to 90 to 105 DEG  C., preferably 90 to 100 DEG  C., for 60 to 80 minutes, preferably about 70 minutes, until the reaction is complete. Preferably the temperature during the addition of oleum, is such that the sulphamic acid is formed, and precipitated from the sulphur dioxide while the oleum is being added. The sulphur dioxide and urea may be preheated and thereafter brought together or they may be introduced into a heated zone wherein the necessary temperature is maintained.  The oleum may be predissolved in a portion of liquid sulphur dioxide and thereafter the mixture is added to a mixture of urea and liquid sulphur dioxide.  Optimum yields of sulphamic acid are obtained when the urea, sulphur trioxide and sulphuric acid are used in substantially equimolar proportions.  Molar ratios of sulphur trioxide to urea of 1 : 1 to 1.3 : 1 may be used, and the molar ratios of sulphur dioxide to urea are preferably 10 : 1 to 25 : 1, especially 15 : 1 to 20 : 1.  Another embodiment involves adding sulphuric acid to a mixture of liquid sulphur dioxide and urea, at about 60 DEG  C., to form urea bisulphate, to which sulphur trioxide is added over 7 to 15 minutes, while maintaining the temperature between 57 DEG  and 60 DEG  C.  After the addition of sulphur trioxide the temperature is allowed to rise to 60 DEG  yo 90 DEG  C., until the completion of the reaction, which is usually 165 to 210 minutes.  Example 1 refers to liquid sulphur dioxide and urea being charged under 14 kg./cm.2 gauge pressure, and warmed to 87 DEG  C. at which stage oleum is added over 6 minutes without cooling.  The temperature rises to 94 DEG C., and the pressure to 17.5 kg./cm.2 gauge. The reaction is completed at 92 DEG  to 100 DEG  C.

Patent GB-217277-A (GB)
Title: Production of activated nitrogen
IPC: C01B21/02
Filed: 1923-02-28
Abstract: Nitrogen oxides are produced by exposing nitrogen to the energy developed when carbon monoxide is exploded with excess of oxygen at an initial pressure of at least 30 atmospheres, preferably 75 atmospheres.  The nitrogen is rendered active and immediately combines with the excess of oxygen.  The carbon monoxide may be exploded with the calculated quantity of oxygen required for the combustion but the oxygen required to combine with the nitrogen must then be introduced into the explosion chamber immediately after the explosion for the activity of the nitrogen does not persist.  The presence of hydrogen is not desirable but a gas such as blast furnace gas containing a small quantity of hydrogen may be employed in place of pure carbon monoxide.

Abstract: 1,093,332. Valves. MeGRAW-EDISON CO. Feb. 10, 1966 [Aug. 26, 1965], No. 5881/66. Heading F2V. In an electric arc furnace where the electrode is consumed to form an ingot, a valve 22 for controlling communication between the furnace at 38 and its vacuum producing apparatus at 35 is shown in its closed position in which a piston 47 is urged upwardly by pressure in a cylinder 46 to cause a main valve disc 42 to engage its seat 32 and a pilot valve 44 to engage a seat on the rear of disc 42, the latter having a lost motion connection with the pilot valve by being located between the seating surface of the latter and a collar 61. Under these circumstances the furnace would be at atmospheric pressure to allow the ingot to be removed and the used electrode to be replaced. To evacuate the furnace, cylinder 46 is depressurised and the pilot valve drops until collar 61 engages disc 42, the latter remaining seated due to atmospheric pressure in chamber 29. The furnace and chamber 29 are then evacuated slowly through restricted ports 58 in disc 42 until the pressure differential across the latter is removed. At this point, the disc 42 and pilot valve drop to the position shown in phantom. In Fig. 1, not shown, two furnaces (10, 11) are connected to a common vacuum source (18) via respective valves (22) as above.
