Title: Improvements in methods of treating porous materials
IPC: D21H17/06
Filed: 1937-11-18
Abstract: 505,989. Coating-compositions applied melted. LUCKHAUPT, C. Nov. 18, 1937, No. 31806. 'Convention date, Nov. 30, 1936. Drawings to Specification. [Class 95] [Also in Groups VIII and IV] Porous materials are treated by immersion or spraying with terpin hydrate admixed with one or more fortifiers at a temperature equal to or higher than the melting-point of terpin hydrate, i.e. at or above 115‹ C. Preferably the ambient atmosphere is maintained at a similar temperature. Fortifiers are defined as substances which themselves improve the properties, e.g. hardness, water- and fire-proofness, of the porous materials. Porous materials include wood such as balsa wood, straw, grass, reeds, textiles, rayon, paper, paper pulp, cellulose, hydrated cellulose, gypsum, hydrosilicates, and articles made therefrom as moulded objects, boxes, wallboards, tubes, rods, &c. Waterproofness is enhanced by the addition as powder of aluminium sub-acetate, aluminium, cupric, calcium or zinc stearate. Fire-resistance is increased by the addition of zinc acetate, aluminium sub-acetate, or ammonium acetate. Resistance to rot, barnacles, termites and other vermin is increased by addition of cupric stearate, creosote, zinc acetate or zinc stearate. Electric insulation is improved by addition of lead stearate, alone or with a natural or synthetic wax, montax wax, carnauba wax, para gum or castor oil. Hardness is improved by the addition of manganese oleate or magnesium stearate. Resilience or pliability is enhanced by addition of camauba or ceresin wax, whereby also a gloss is imparted, or para gum or castor oil. Addition of triphenyl phosphate increases hardness, waterproofness and fireproofness. The addition of cellulose acetate with triphenyl phosphate renders the material proof against water and alcohol. The addition of a mixture of zinc acetate, triphenyl phosphate, aluminium acetate and aluminium stearate imparts fire and water resistance. Addition of strontium glycerophosphate also imparts proofness against carbon tetrachloride, turpentine and hydrocarbons ; with paraffin wax imparts proofness against alcohol, ethyl, butyl, and amyl acetates and the mono-methyl, mono-ethyl, and monobutyl ethers of ethylene glycol ; with shellac or cellulose acetate imparts oil-proofness. Waterresistance, toughness and durability are imparted by an admixture of cellulose acetate, triphonyl phosphate and natural or synthetic resins such as ester gum, gum dammar, shellac, phenolic resins, or the resins known under the Registered Trade Marks " Glyptal," " Rezyl," and " Vinylite." Vegetable oils such as castor, perilla, linseed, rape seed, tung, or soya bean oils may replace the resins. The treatment may be carried out as described in Specification 482,847. Materials treated according to the invention may be subsequently coated with shellac, varnish, oil paints, cellulose derivatives, lacquers, synthetic resins, casein or albumen.

Title: Improvements in heat exchanger and boiler construction for a sea water evaporator
IPC: C02F1/16
Filed: 1956-10-19
Abstract: An evaporator of the "basket" type, such as is used aboard ship for distilling water, comprises a substantially vertical shell having a plurality of straight sides and a wide sideopening, provided with a detachable cover 38, through which the heat exchanger 18 can be removed from the boiler chamber C when it becomes necessary to clean the exterior of the heat exchanger or the interior of the boiler. Beneath the heat exchanger is disposed a sump 34.  The heat exchanger has a generally cylindrical <PICT:0826989/III/1> <PICT:0826989/III/2> <PICT:0826989/III/3> wall provided with deep radially projecting corrugations 44 which define internal recesses 46 and external recesses 48.  A ring 56 is welded to the bottom of the cylindrical wall of the heat exchanger; and the ring is secured to a cylindrical shell 58 which is bolted by flange 60 to the bottom of the boiler. Inside the heat exchanger is disposed a skirt 64, the lower part of which is imperforate, while the upper part 68 is perforate and joins the top header 54.  The lower part of the skirt comprises a frusto-conical section 70, the bottom edge of which slides over the upper end of the inlet conduit 72 for the heating medium, e.g. steam. A collar 74 is secured to conduit 72, and this forms an annular trough which is packed with grease G to seal the connection between the heat exchanger and the conduit.  When the heat exchanger is to be removed, cover 38 is detached, the bolts are unfastened from flange 60 and the heat exchanger and skirt are slightly lifted, as a unit, so that the bottom edge of the skirt will clear the top end of conduit 72; the unit is then withdrawn through the side opening of the shell.  Sea water is introduced into the boiler through conduit 26.  The steam, supplied through conduit 72, passes through the perforations in the upper part of the skirt, and then flows down through the recesses 46.  Steamcondensate is received in sump 34, and is withdrawn through conduit 36.  Boiling sea-water rushes up the recesses 48; and steam is separated from the mixture at the apex formed by conical plates 23 and 25.  The hot water falls back to the lower part of the boiler.  Steam, containing some entrained water, passes through conduit 20 and is introduced tangentially into chamber S where the water is separated out by centrifugal action.  This water flows into sump 22 and drains away through conduit 24.  Brine is discharged from the boiler through conduit 28.  The steam from chamber S may be led to a second separating chamber, and then to a condenser.  Specifications 674,385, 811,474 and 824,354 are referred to.

Title: Improvements in or relating to mechanisms for the remote control of start-stop apparatus by electric signals
IPC: H04L17/18
Filed: 1952-12-19
Abstract: 717,657. Printing-telegraph receivers. SIEMENS & HALSKE AKT.-GES. Dec. 19, 1952 [Dec. 21, 1951], No. 32304/52. Class 40 (3) In a mechanism for the remote control of start-stop apparatus by electric signals, an electromagnet operated by the signals is arranged to effect a control operation on de-energization and the armature of the electromagnet is free of all restraint by externally acting forces when in the inoperative position, and also during its initial movement when re'eased, so that it acts with substantial momentum on the members controlled thereby when the electromagnet is de-energized. As shown the mechanism is used for the control of the receiver shaft of a start-stop telegraph system in which the electromagnet 1 is energized during the stop condition and the armature 2 is free from mechanical restraint. On the arrival of the start signal element the magnet 1 deenergizes, releasing the armature 2 which moves freely under the action of a biasing spring PI until an extension 12 impacts a projection 11 on a re'ease lever 5 which is raised so that a projection 7 on a cam on the clutch-driven receiver shaft 6 can rock a latch member 4 beyond the position of latching engagement, the latch member 4 being restored to its normal position by a spring P4. Towards the end of the revolution of the shaft 6 a projection 8 on the cam sleeve engages the lower arm of a two-armed lever 9 so that its upper arm engages and rocks the armature 2 clockwise to its inoperative position, in which it is held by the energized electromagnet 1. At the same time the lever 5 rotates under the action of its spring P2 to its normal position, against a stop 10, in which it engages a projecting finger on the latch 4 of which the lower end engages the projection 7 to arrest the receiver shaft in the stop position.
