Title: Improvements in or relating to instruments including springs
IPC: G01N3/06
Filed: 1949-05-11
Abstract: 711,205. Hygrometers; determining specific gravity; thermometers. ANGLO-IRANIAN OIL CO., Ltd., and TOMASCHEK, R. K. A. Aug. 11, 1950 [May 11, 1949], No. 12543/49. Class 97(3) [Also in Groups XIX, XXXII, XXXVIII and XL(b)] An instrument for measuring or comparing linear forces of like direction comprises a coiled spring 36, Fig. 12 having a cross-section of substantial width to thickness ratio and having not less than 1.25 turns in the unextended state and capable of linear movement under the action of a linear force applied at one end, the spring being mounted so that the axis of the spring in the unextended state is inclined at an angle not greater than 40 degrees to the direction of the force; the angle being such that under the influence of the force the spring is extended into a state of extreme sensitivity. The spring is in such a state when the mounting angle is such that the graph of angle of twist against load is a simple inflection curve having the maximum sensitivity for twist and the load is that at which the latter occurs. As applied to a thermometer the base plate 32 adjusted by screws 33 carries a casing 34 which supports a mounting 35 for the spring allowing the axis of the latter to be rotated in two mutually perpendicular planes. The lower end of spring 36 bears a pointer 37 and is attached to a torsion wire 38, the opposite end of the latter being attached to a bimetallic strip 39 supported on a movable support 40 operated by a rack and pinion 41 for bringing the spring 36 into its extremely sensitive state. A hygrometer according to the invention comprises the adjustable spring mounting 14, Fig. 11, carried by the casing 13 supported on base plate 11, the lower end of spring 15 being attached to mirror 16 and a fine torsion wire 17, the opposite end of the latter being fastened to a hygrometer hair 18 supported by a rack and pinion adjustment 19. In the gas density measuring instrument the sealed casing 44, Fig. 13, provided with gas inlet 52 and outlet 53 supports the adjustable spring mounting 45. The sensitive spring 46 is attached at its lower end to mirror 84, the weak helical spring 47 and torsion wire 50, the latter carrying a light hollow pear-shaped vessel 51. The upper end of spring 47 is secured to a movable framework 48 operated by rack and pinion 49. The distortion produced in the spring under the action of an applied force may be measured by observing the elongation by means of a microscope, or the variations in capacity of a variable condenser, or the changes in ionisation currents produced by a radioactive material attached to the spring. Alternatively optical, electrical, or radioactive means may be utilized for measuring the angular displacement of the free end of the spring. Specification 711,206 is referred to.

[Class 38(v)] [Also in Group XXXV] In an electrical control system for an electric oven, an expansible diaphragm 9 connected with a bulb in the oven and adjustable to determine the control temperature by a rotary dial 7 operates upon an element 16 of a snap-action switch comprising contacts 43 in the main circuit supplying a " bake " element through a normally closed switch and a " broil " element through a contact 55 of a second snap-action switch which has a normally closed switch 105 co-operating with it by means of a pin 111 to complete the broil circuit. A member 71 transmits the thrust of the diaphragm from the main switch lever 24 to the lever 58 of the broil switch. The pushing in of lever 80 causes the withdrawal of the member 71 against a restoring spring 79 at the same time causing the broil switch to close by means of an arm 81 of a resetting lever 72 which co-operates with a projection 82 in the broil switch lever 58, the two members 71, 72 being connected together. The lever 80 also opens the bake switch 87 by pushing on pin 90, and is operated manually by turning the broil handle which is fixed to the rod 114. A projection 121 in a member 119 cooperates with a cam surface 116 in a bush 115 fixed to the rod. The member 119 moves against spring 120 inserting the lever 80 which is connected by member 123. A lever 129 co-operates with a projection 98 in the main handle 7 which moves the broil handle to " off " position. This projection 98 has a cam surface which pushes in the lever 80 when the main handle is in the high position. Specification 539,481 is referred to.

Title: Extraction of deuterium from hydrogen gas using amines in a bithermal process
IPC: B01D59/33
Filed: 1970-03-18
Abstract: 1,273,461. Deuteration of amines. ATOMIC ENERGY OF CANADA Ltd. 18 March, 1970 [8 April, 1969], No. 13021/70. Heading C2C. [Also in Division C1] In a bithermal extraction of deuterium from, e.g. ammonia synthesis gas, the gas passes in flow path 1, 1a 1c through hot and cold exchange towers H, C to countercurrently contact with a first exchange liquid flowing in path 3, 3a and exchange tower E, and a second different exchange liquid flowing in path 2, 2a, E. The exchange liquids are selected from aliphatic amines having up to five carbon atoms per molecule and mixtures thereof with ammonia. The exchange liquids may have a catalyst dissolved therein e.g. made by dissolving lithium, sodium, potassium, cesium or rubidium or an amide thereof in the exchange liquid. The gas picks up deuterium in the hot tower H but loses a greater amount in the cold tower C. The second exchange liquid exists mainly as a vapour in exchange tower E and hence loses some catalyst to the first exchange liquid. To compensate this a portion 3b of the first exchange liquid is admitted to the second exchange liquid cycle. In the tower E deuterium passes to the first exchange liquid which can then be bled off via path 3c to a second deuterium exchange system, having hot and cold towers H 1 , C 1 , before returning via 3e. In the second exchange system hydrogen gas passes through path 4, H 1 , 4a, C 1  and picks up deuterium at H 1  but loses it at C 1 . A portion 3f of the first exchange liquid, concentrated in deuterium is then contacted with ammonia gas in exchange tower E 1 . The two amine system of the first stage may be used in the second deuterium exchange system. Amines specified are 1, 2- and 1,3- diaminopropanes, aminoethane and diaminoethane.

Title: Improvements in or relating to methods of and apparatus for heating or cooling liquids or admixed solids and liquids in evaporative and like treatment thereof
IPC: B01D1/26
Filed: 1921-05-10
Abstract: 187,260. Rigby, T. May 10, 1921. Drawings to Specification. Multiple-effect apparatus; vapours, utilizing for effecting further evaporation; crystallizing. -In evaporating liquids in multiple-effect apparatus, particularly of the kind described in Specification 180,963, in which the liquid is fed in parallel to the effects, the liquid is passed in series through a number of multiple-effect plants, the temperature ranges of which coincide or overlap substantially. In concentrating brine or other liquid the boiling-point of which rises on evaporation, the first effects of each plant are preferably supplied with steam from the same source and the last effects are connected to the same condenser, and the number of effects in each succeeding plant is progressively diminished. In evaporating cane or beet sugar solutions, the concentration obtained in the last plant may be such that crystals separate in the effects of this plant, or crystallization may be effected outside the plant in crystallizing vessels which may be supported on wheeled devices or in heated pans in which slow evaporation takes place. When the concentrated liquid is to be cooled to cause crystallization or for other purposes, the vessel containing the liquid is connected to the vapour spaces of effects at progressively lower pressures as to cause the liquid to flash off steam and to lower the temperature in stages. The method of cooling the concentrate and recovering the heat for use in the evaporating process may be used in plant in which the multiple-effect apparatus is replaced by apparatus of the kind described in Specification 12462/11, in which the vapours evolved on evaporation are compressed and used as the heating-agent. In concentrating impure liquids such as seawater, which at one stage of the concentration will deposit impurities, such as calcium sulphate &c., on cooling, the cooling may be effected by flashing-off vapours from the solution by connection with effects of lower pressure, during the passage of the solution from one evaporating plant to the next. The solution may be preheated before passage into the next plant by heat-exchange with the solution from the first plant. According to one Provisional Specification, the control device described in Specification 180,963 for controlling the passage of vapour from one effect to another may be used also to control the inflow of liquid into the effect.
