Abstract: 816,214. Hot water supply systems. RANGE BOILERS Ltd. March 21, 1956 [April 7, 1955], No. 10221/55. Class 64(1) A primary hot water system, heating the draw-off water in a storage vessel f by means of a heat exchanger b in the latter, receives its water from that vessel, and has within the storage vessel two air traps. The heat exchanger is filled through the first trap d, e, and the second is provided in a vent pipe c connected to the heat exchanger. The arrangement is such that the primary water in the heat exchanger is not displaced into the draw-off water. In one form, Fig. 1, water enters the first air trap, formed by partitions d, e within the top of a vertical cylindrical heat exchanger, through an opening g, and overflows the top of the partition d. In a modification, the heat exchanger is horizontal, and during filling water overflows from a vertical pipe into an air space formed by a partition depending from the top of the heat exchanger. In another form, the air trap is outside and above the heat exchanger, and is connected to it by a short pipe. In another form, Fig. 3, the air trap is formed at the bottom of an annular heat exchanger b connected to a boiler, by two annular walls o, p of angle-shaped cross-section.

Abstract: 541,847. Artificial filaments dyeing processes ; proofing. SPEAKMAN, J. B., and CEFOIL, Ltd. June 12, 1940, No. 10269. [Classes 2 (ii) and 15 (ii)] [Also in Group VIII] In the manufacture of artificial filaments having a basis of alginic acid or an alginate, the filaments are subjected to the action of a compound of a metal of high co-ordinating power such as chromium so as to combine the alginic radical with the metal and render the filaments resistant to alkali. The metal compound may be salt in polymerized form, e.g. basic chromium acetate. In an example chromium hydroxide, freshly precipitated from chrome alum with ammonia is washed and pressed and then ground up with glacial acetic acid. Water is added and the solution is aged for several hours until all the crystalline solid is dissolved. The solution is then warmed for some minutes. When required for the treatment, the solution is diluted with water or dilute acetic acid. Hanks of alginate yarn are immersed in the solution of basic chromium acetate and subsequently washed and dried. The yarn which is of a greyish-violet colour is resistant to alkali. Drying at elevated temperature further increases the alkali-resistance. The chromium alginate yarn has an affinity for chrome mordant dyes. The alginate filaments may be obtained by extruding a solution of sodium alginate into an acid coagulating bath containing emulsified oil and they may be hardened by treatment with alum or calcium chloride before being subjected to the treatment with a chromium compound. Specification 541,848 is referred to.

Abstract: 873,081. Photo-electric exposure control. KODAK Ltd. March 25, 1960 [March 25, 1959], No. 10571/60. Class 40(3) In a photographic camera, the position of an exposure regulating member is determined by contact with a slide member arrested by a photoelectrically energized galvanometer pointer. Actuation of the camera release first releases the slide 4 which moves parallel to the pivotal axis of meter 2 under the action of a spring 6 to contact the pointer 1. Further actuation of the release allows the slide 7 to move until a lug 7b contacts the control surface 4b, thus rotating a shaft 10 to regulate the exposure. Alternatively, Fig. 4 (not shown) the control surface is on slide 7 and co-operates with a lug on slide 4. Surfaces 4c, 4d arrest the slide in a position which prevents operation of the camera when the light is unsatisfactory. The meter may be rotated to allow for film speed and filter density.

Abstract: 270,680. Parker Rust Proof Co., (Assignees of Willard, H. H., and Green, M.). May 10, 1926, [Convention date]. Manganese and iron phosphates.-A rustproofing compound is made by forming an impure solution oi manganese dihydrogen phosphate in phosphoric acid, crystallizing the phosphate, separating the crystals and drying them under oxidizing conditions. In a preferred procedure, ferromanganese containing about 80 per cent of manganese and 6-10 per cent of iron, is dissolved in a strong (e.g. 65 per cent) solution of phosphoric acid, with the aid of heat and agitation. The solution is filtered to remove undissolved metal, carbon, silica, &c. and cooled to crystallize the phosphates. The crystals are exposed to air while drying to oxidize the ferrous phosphate to insoluble ferric phosphate. The dried crystals may, if desired, be placed in water and the solution of manganese phosphate removed to crystallize out a substantially pure product. Any material which is soluble in phosphoric acid to produce manganese dihydrogen phosphate without introducing difficultly removeable or detrimental materials such as sulphuric acid, chlorine &c. may be used instead of ferromanganese. Such materials comprise alloys of manganese other than ferro-manganese. Specification 270,679, [Class 82 (ii), Washing granular &c.], is referred to.
