Title: Improvements in or relating to heating systems employing circulating hot water
IPC: F24D9/02
Filed: 1937-03-15
Abstract: 475,767. Heating by circulation of fluids; feedwater - storage apparatus. JACKSON, L. MELLERSH-. (Kraftanlagen Akt.-Ges.) March 15, 1937, No. 7568. [Classes 64 (i), 64 (ii), and 123 (ii)] In a heating system of the kind in which hot water is circulated between a steamheated mixing - preheater and the consumers, a boiler 1 supplies steam to a turbine 3 and to other consumers at 4. The turbine discharges in part to a preheater 5 from which hot water is extracted by a pipe 6 for supply to consumers 8. Water returns through valve 10 to a distributer 11 in the steam space of the preheater. A pipe 12 connects the boiler to the flow pipe 7, and valve 13 is controlled by the water level in the boiler. The water in the heating system may vary in volume, such variations causing level variations between a and b in the preheater 5. If the level falls below b, water is supplied to the system by a pump 14. The steam condensed from turbine 3 and used by consumers 4 may be fed direct to the boiler 1, or water may be forced by pump 14 into preheater 5, and the whole of the boiler feedwater supplied through pipe 12. In Fig. 2, a boiler 21 supplies steam to consumers 23, 24, and the preheater is arranged in a storage chamber 25, a layer of Raschig rings 27 being used to facilitate the condensation of steam. Hot water is supplied through pipe 29 and returns through pipe 30. The water level may vary between a and b. The return water is also forced by a pump 31 through valve 32 to the sprayer 26 and through valve 33 to a flue gas preheater 34. Valve 32 is controlled by the pressure in the steam pipe 22. Hot water is stored in the upper part of chamber 25, the plane of separation from the colder water moving downwards as it accumulates. Water from the preheater 34 passes into the boiler 21 according to the level in the latter, or into pipe 37 for supply to consumers. A mixing preheater, Fig. 3, comprises a container 41 having an aperture 42, through which internal fittings are introduced, closed by a cover 43. The water inflow pipe 44 is provided with an overflow 45 carried by crossbars 49, and the pipe 44 also carries a distributer 50 supported by rods 51. A further distributer 52 consists of 3 segments to facilitate introduction through opening 42, supported on members 53, 54.

Title: Improvements relating to the production of pitch mastic
IPC: C08L95/00
Filed: 1947-03-19
Abstract: An oil for use in the preparation of a pitch mastic (see Group V) is prepared from the middle tar oil fraction produced in the low-temperature carbonization of coal.  The fraction is washed successively with 30 DEG  Tw. caustic soda solution to remove tar acids, 3 per cent by volume of 40 per cent sulphuric acid, 1 1/2 per cent by volume of 80 per cent sulphuric acid, water, 30 per cent caustic soda solution to neutralize free acid, and 4 per cent by volume of 60 DEG  Tw. caustic soda solution.  The resultant is then distilled at 190-225 DEG  C. under reduced pressure to produce a product of initial boiling-point of over 300 DEG  C.ALSO:Pitch mastic for use particularly as flooring is prepared by incorporating a coarse and a fine aggregate into a coal-tar pitch to which has been added a fluxing oil consisting mainly of aromatic hydrocarbons compatible with pitch, having an initial boiling point of approximately 300 DEG  C., and evolving no noxious or irritant fumes when heated during laying of the mastic.  The pitch is preferably one produced during the low-temperature carbonization or distillation of coal and has a full carbon content of not more than 10 per cent, while the fluxing oil may be obtained from the middle oil fraction boiling between 200 DEG C. and 330 DEG  C. produced during low temperature carbonization or from a mineral oil fraction.  The middle oil fraction from which the fluxing oil is obtained is composed of 45 per cent by volume of crude phenols, 12 per cent paraffin hydrocarbons, 14 per cent olefines, 26 per cent aromatic hydrocarbons and 3 per cent crude bases, and of the fluxing oil obtained therefrom 15-40 per cent distils at 345 DEG  C. and 3.6 per cent is lost by evaporation at 325 DEG  C.; corresponding figures for the mineral oil fraction are 3.5 and 0.6 per cent respectively.  The fluxing oil is obtained from the middle oil fraction by treating chemically for the removal of the acids and bases and then distilling under reduced pressure (see Group III).  The mastic is prepared by mixing the substances together at a temperature not exceeding 160 DEG  C., there being present 9-19 per cent of pitch 1-3 per cent of fluxing oil and the remainder aggregate which may include an absorbent filler such as sawdust (preferably from a hard, non-resinous, and low moisture-content wood) up to 50 per cent by weight of the mastic, and a pigment.  Specification 568,705 is referred to.  According to the Provisional Specification, the fluxing-oil may be incorporated in an asphalt mastic.

Title: Improvements relating to ventilators and to the control of flow of fluids
IPC: F24F13/15
Filed: 1943-05-13
Abstract: 569,013. Ventilators. DAVIES, L. G. May 13, 1943, No. 7660. [Class 137] [Also in Group XXIX] Fluid control means serving as a ventilator or used, e.g. in front as a protecting baffle against a sudden rush of air or liquids, comprises a set of louvres, one over another, with overlapping surfaces at each side of an intermediate plane, the louvres being supported well below the internal surface at the top of each by bearings permitting tilting and narrowing or closing of the inter-louvre passages under varying pressure conditions. A wall ventilator comprises a metal casing 25 with outer and inner grids 28, 29 and end channels 30 holding rubber, fibre, &c. strip 31 supporting the inverted V projections 35 of louvres 32 in rectangular holes 33. The projections are offset towards one side of the apex of the louvres which are supported when at rest with both supporting surfaces of the projections resting on the floor of the holes. As the pressure of incoming air increases above a predetermined value, the louvres begin to tilt about the offset edges of the projections until resilient stops 34 are engaged, the narrow gap 'thus left being closed altogether, as by a gust of wind of gale force or a splash of water in the case of ship ventilators, by the stops themselves yielding slightly. Reversed currents cause the louvres to tilt about the centrally situated edges of the projections. Modifications include Z-shaped louvres with grummets mounted on the louvre blades in place of the fixed stops 34 and the inner blades may be weighted to assist in restoring the louvre to normal position. The casing may have inclined baffles at inlet and outlet tending to increase the pressure on the louvres. Instead of metal sheet, the louvres may be made up of fibre, cardboard, asbestos, &c. strip held at the ends by metal plates. Manual adjustment of the louvre set may be provided by a rod 53, Fig. 12, operable from outside the casing as by a lever 56 so as to cause wedges to bear on the pivoting edges of the supporting projections. A box 51 with holes 52 in this construction replaces the strips 31. Alternative forms of louvre 'supports include a horizontal plate, a round bar, a rubber strip and curved metal tongues which may be covered by a rubber band.
