Title: Improvements in and relating to the control of feed water supply to boilers and generators
IPC: F22D5/14
Filed: 1940-05-20
Abstract: 541,449. Feed-water regulators. ARMSTRONG, C. H., BROWN, N. H., and COPES REGULATORS, Ltd. May 20, 1940, No. 8959. [Class 135] An apparatus for controlling the supply of feed water to steam boilers in which the main feed valve is actuated by differential pressure has one of the actuating pressures variable by a control valve actuated by means responsive to the water level and the load on the generator. In the form shown in the Figure, the main feed valve 8 is formed integrally with a plunger 12 subject to feed pressure admitted through a passage 17 throttled by a needle valve 18 and with a leaky piston 10 subject on one side to boiler pressure and on the other to a variable pressure controlled by a needle valve 14 cooperating with a seat removably secured to the plunger. The valve 14 is actuated by a floating lever 16 one end of which is pivoted to a float-actuated lever turning on a fixed pivot 23 while the other end is coupled to a lever 25 turning on a pivot 26 and connected by a link 27 to a bellows 28. The bellows, which is adjustably loaded by a spring 31, has its open end secured to an annular plate while its closed end is guided by a spider 29, collapse of the bellows being limited by a stop 32. The outside of the bellows is subject to the pressure in the float chamber 3 which is connected to the generator by pipes 4, 5, while the outside of the bellows is subject to the pressure in the steam main on the discharge side of a superheater so that the presdifferential gives a measure of the steam flow. In a modification the float lever is pivoted on a link joined to the lever 26 and is linked directly to the pilot valve spindle. In a further modification the pilot valve spindle is connected by a link and lever to the midpoint of a floating lever one end of which is coupled by a link including a compression relief spring to a lever connected to a spring-loaded diaphragm subject to superheater inlet and discharge pressures. The other end of the floating lever is coupled by a link including a tension relief spring to one end of a spring-loaded bell-crank lever actuated by an inclined expanding tube connected by piping at both its free and anchored end to the generator. Specifications 418,208 and 491,271 are referred to.

Abstract: 764,067. Electrodialysis. PERMUTIT CO., Ltd. March 25, 1954 [April 7, 1953], No. 9420/53. Class 41. In a process of electrodialysis in a multicompartment cell having an anode compartment and a cathode compartment and at least five intermediate compartments between the two electrode compartments, the compartments being separated from one another by alternate cation and anion exchange diaphragms, an anion exchange diaphragm being next to the anode and a cation exchange diaphragm next to the cathode, one solution is passed continuously in one direction through every alternate intermediate compartment and a second different solution is passed in the opposite direction through the remainder of the intermediate compartments, while a direct current is continuously passed through all the compartments in series. The solutions in the electrode compartments may be continuously changed. The liquid leaving one set of intermediate compartments may be passed through one of the electrode compartments. A solution having lower electrode potentials than the electrolyte being treated and having a reaction at the cathode which is the reverse of the reaction at the anode may be continuously circulated between the two electrode compartments, as described in Specification 764,068. An illustrated embodiment shows a cell comprising five intermediate compartments 1, 2, 3, 4 and 5 between an anode compartment 6 containing an anode 10 and a cathode compartment 7 containing a cathode 11. These compartments are separated from one another by anion exchange diaphragms 8 and cation exchange diaphragms 9. A solution from which a dissolved electrolyte is to be removed is fed to compartment 1 and flows thence to compartment 3 and then to compartment 5. At the same time a solution to receive the electrolyte removed from the first solution is passed through compartment 4 and then through compartment 2. The diaphragms may be made With peripheral projections to hold them apart and cooperating holes formed in the projections so that the solutions may flow through the conduits thus formed and enter and leave the compartments through passages connecting the holes with the compartments. The two end diaphragms are shielded on the sides nearest to the electrodes by further diaphragms 12 of ordinary macroporous material, e.g. porous ceramic material, whereby the products of electrolysis produced at the electrodes are hindered from diffusing towards and attacking the ionexchange diaphragms. The liquid leaving compartment 5 may be passed through compartment 6 or alternatively the liquid leaving compartment 2 may be passed through compartment 7.

Abstract: 1,152,972. Two-phase hair conditioning composition. SALES AFFILIATES Inc. 28 Feb., 1967 [27 May, 1966], No. 9583/67. Heading A5B. A two-phase hair conditioner comprises an aqueous phase containing a quaternary ammonium compound having at least 15 carbons and at least one saturated or unsaturated alkyl group containing at least 10 carbons, and a water imiscible liquid phase which is a non-solvent for the quaternary ammonium compound, has no water-solubilising groups and evaporates at room temperature at a rate similar to water. The quaternary ammonium compound may be oleyl dimethyl benzalkonium chloride, distearyl dimethyl ammonium chloride, or stearyl dimethyl benzyl ammonium chloride, and is suitably used in a quantity by weight of the water phase, of 0.03-1.0%. Suitable water imiscible liquids are hydrocarbons such as petroleum fractions distilling between 345 and 525F., for example deodorised kerosene and synthetic iso-paraffinic solvents such as Isopar, (registered Trade Mark) which is a mixture of 95% saturated branched chain isoparaffins with 5% naphthenic cycloparaffins. Other such liquids are halogenated hydrocarbons, such as chloroform, carbon tetrachloride, trichlorotrifluoroethane, and trichlorofluoromethane, or ketones, alcohols or ethers. Preferably a mixture of paraffins and halogenated hydrocarbons is used. The ratio of water phase to water-imiscible phase may be from 0.5 to 30:1, preferably 2 to 5:1, by volume. Other hair treatment agents may be incorporated into either phase depending upon their solubility in water or oil; for example the water phase can contain hair setting agents, e.g. mannitol or polyvinyl pyrrolidone and its vinyl acetate copolymer; water soluble sun-screening agents, e.g. 2-hydroxy-4-methoxybenzophenone-5-sulphonic acid; oxygen absorbing agents, e.g. monoethanolamine sulphite and optical brighteners e.g. pyrazoline sulphonic acid, or Tinopal, (Registered Trade Mark). The water-imiscible phase may contain oil soluble sun-screening agents, e.g. methylanthranilate or salicylate; oil soluble hair colourants, e.g. D and C Violet No. 2 and Red No. 17; lustre imparting substances, e.g. iso propyl myristate; nacreous agents, e.g. guanine crystals, and oil soluble optical brighteners. The invention includes a method of conditioning the hair by application of the composition.

[Class 44] [Also in Group XXXIII] A fastening particularly for the folding wings of aircraft comprises oppositely moving pins f connected to the ends of a first-order lever k by pivotal movement of which the pins may be inserted in or removed from apertures formed in pairs of lugs d mounted on the wing stub shown and in lugs b mounted on the folding wing, not shown, the apertures registering when lugs b are sandwiched between lugs d as in Fig. 1, which shows the parts in fastening position. Lugs b and the spaces in which they fit are preferably wedge-shaped and the parts arranged so that pins f are inclined to the horizontal at approximately 30 degrees as shown. Lever k is operated by a link connection o to a sleeve p pivoted at r and having slidably disposed therein a rod q, the parts p, q forming a telescopi'c operating means. The lever k is bifurcated or apertured as seen in Fig. 3 and in the fastened position the rod q is disposed through the aperture with its inner end entered in an annular supporting bracket S. The aperture in lever k is so formed and disposed that rod q can pass therethrough only when lever k is in locking position, and rod q, disposed as in Fig. 1, locks lever k against movement to release position. To effect release, rod q is pulled out to the position shown dotted, Fig. 2, with its inner end clear of lever .k. Parts p, q are then depressed to the position shown in full lines, thus rocking lever k to withdraw pins f. Fig. 2 also shows the lugs b as moved clear of lugs d in the wing-folding operation. Rod q may be held in its inner position by a spring-plunger catch w which must be released before rod q can be pulled out. The fastening and operating means may be disposed in the usual gap between the contiguous faces of the stub and wing, or in recesses in either or both of these parts, and such recesses may be closed by a cover flap t conforming in shape to the section of the wing. As shown, lugs b, d are disposed in the region FS of the front spar, and similar lugs, c, e with locking pins g and lever m are disposed in the region RS of the rear spar, lever m being operated by link connection u with lever k. Lever m is not apertured to co-operate with rod q. Link u may be supported intermediate its ends on an idler link v.
