Title: Improvements in or relating to the manufacture of paper or like fibrous material
IPC: D21H17/68
Filed: 1942-03-16
Abstract: 554,556. Paper of high wet strength. JACKSON, Ltd., H., and WEXLER, A. March 16, 1942, No. 5232/43. Divided out of 554,131. [Class 96] The strength, particularly the wet strength of paper &c. is increased by treatment with silicic acid made by reacting a soluble silicate with an acid solution, so that insoluble hydrated silica is bonded to the fibres when water is given off in drying, or when an insoluble silica gel is formed spontaneously. Acids used may be sulphuric or hydrochloric, or phosphoric, acetic, lactic, formic, or oxalic, or a mixture of a strong mineral acid with a little weaker acid so that a small excess of acid left in the paper is the weaker acid, the pH value of the silicic acid solution not exceeding 2.8. Alkali metal salts formed by the reaction may be removed by washing the dried paper with water or by allowing time for a silica gel to form and washing, or by removing the salts from the solution by dialysis. Excess acid in the paper may be neutralized by alkali, removed by soaking the paper, or removed with the alkali metal salts by washing after gel formation or after partially drying. The process is applicable to paper made from pulp which has been treated with a silicate and alum. The treated paper may retain high absorbency and permeability to water, or may be waterproofed by waxes, oils, or resins. The silicic acid solution may be applied to the wet web on the paper-machine. Specification 554,131 is referred to.

Title: Improvements in and relating to controls for liquid or gas fired heating apparatus
IPC: F24C5/16
Filed: 1953-02-26
Abstract: 742,003. Photo-electric furnace control. STEFANI, A. G. U. Feb. 26, 1953 [Feb. 28, 1952], No. 5463/53. Class 40 (3). In plant for the combustion of fluid fuel a relay operated by fuel pressure is arranged to interrupt the fuel supply after a certain delay if ignition of the fuel does not take place and is, in consequence, not detected by a photoelectric cell, the cell also operating to cut-off fuel supply if ignition fails. As shown, manual closing of switch 1 prepares the circuit of 3- phase fuel pump motor M and energizes a relay R1 which in turn completes the circuit of star-connected fuel heaters 2, 3, 4. When the fuel is sufficiently hot, thermostat 5 opens the circuit of relay R1 and thereby the heaters and complete the circuit of motor control relay R2 and the primary of ignition transformer G. Relay R2 completes the circuit of the pump motor M which supplies fuel to the burners. The fuel pressure sets a member TR (vide infra) in motion to open the circuit of relay R2 after a predetermined period by means of a contact KTR. If the fuel has been ignited however a photo-electric cell F detects the flame, operates a relay R3 which moves a member 8 into the path of member TR which is thus prevented from opening its contact KTR. At the same time relay R3 opens the primary circuit of the ignition transformer and transfers the circuit of relay R2 so that it is now in series with the photo-cell. Thus if the flame fails during operation the photo-cell opens the circuit of relay R2. Since the relay R3 has already operated however member 8 is engaged with relay member TR and release of this mem-. ber with consequent closing of the ignition circuit is not possible until the pressure operating member TR has fallen. Other contacts 6, 61 and 7 operated by other safety devices are provided. Pressure-operated time-delay relay (Fig. 2). Pressure from the fuel main enters bellows 12 which expand moving piston 13 against the action of a spring 14. The movement of the piston is transmitted through a spring 16 to a braking piston 20 moving in a cylinder with a small aperture adjusted by screw 25. Thus the time taken by the piston to travel along the dashpot may be adjusted and at the end of its travel a rod 9 is arranged to operate contact KTR which may be restored by hand or by a spring. Motion of the rod 9 may be prevented by relay-operated member 8 which engages in a recess 26 in rod 9.

Filed: 1936-02-25
Abstract: Solid materials are coated with bitumen, which may be in emulsion form, in the presence of an "adhesion assistant" which is a cation active organic derivative of ammonia containing at least one lipophilic radicle in the molecule, or an analogous compound derived from phosphorus, arsenic, antimony or sulphur. Solid materials include stone aggregate and chippings, asbestos fibres, pavings, concrete roads, floorings, ship bottoms, ironwork and the like.  The adhesion assistants include various amines and quaternary ammonium compounds, or salts of amines, particularly those which contain saturated or unsaturated aliphatic radicles of high molecular weight, a large number of compounds being specified.  The suitability of any such compound may be determined by measuring the angle of contact between the bitumen and the material to be coated (or between paraffin oil and any suitable surface) in the presence of water, with and without the adhesion assistant.  If in the presence of the latter, the surface tension is appreciably reduced, it is suitable for use.  In thirty-one examples are included specific substrates to be coated with bitumens (including road tar, asphalt, cut-back bitumen and pitch) and the adhesion assistants for use therewith, some of the examples also giving details of the preparation of bituminous emulsions.  Specification 414,801 is referred to.ALSO:Solid materials are coated with bitumen, which may be in emulsion form, in the presence of an "adhesion assistant" which is a cation active organic derivative of ammonia containing at least one lipophilic radicle in the molecule, or an analogous compound derived from phosphorus, arsenic, antimony or sulphur.
