Title: Process of making soap
IPC: H03H9/09
Filed: 1934-02-10
Abstract: For the manufacture of soap from the oxidation products of petroleum, the products are saponified in the absence of water, and the crude anhydrous product is agitated and heated in a closed vessel in the absence of air while passing in a current of steam, carbon dioxide or vapours of xylene or toluene, and finally unsaponified materials are removed.  The saponification products of hydroxy-acids and lactones are thereby transformed into unsaturated acids by the elimination of the elements of water. Sodium hydroxide or carbonate or potash is used in a small excess as saponifying agent and the crude product is heated in a closed vessel such as a still at 300--350 DEG  C., with a current of steam to agitate the material and prevent local over-heating.  Reduced pressure may be used.  The current of steam also removes unsaponifiable materials such as unchanged petroleum, tars and partially oxidized substances.ALSO:Soap is made from the oxidation products of petroleum, by saponifying the products with alkali in the absence of water, and then agitating the molten anhydrous soap in a closed vessel, while passing in a current of steam, carbon dioxide or vapours of toluene or xylene, and finally removing the unsaponified materials.  The crude saponification products of hydroxy acids and lactones are thereby transformed into unsaturated acids by the elimination of the elements of water. Sodium hydroxide or carbonate or potash is used in a small excess as saponifying agent, and the crude product is heated in a closed vessel, such as a still to about 300 to 350 DEG  C., with rapid agitation generated by a current of steam, to prevent local overheating.  Mechanical agitation may also be employed, and also reduced pressures.  The current of steam removes unsaponifiable materials such as unchanged petroleum, tars and partially oxidized bodies, leaving a white odourless soap.  Animal or vegetable fats or oils may be added to the crude saponified product to produce mixed soaps.

Abstract: 553,424. Directive wireless signalling. DOWSETT, H. M. April 7, 1942, No. 4573. [Class 40 (v)] For producing a beam over a restricted horizontal angle, apparatus mainly below ground level comprises a vertical dipole A, O, B, Fig. 1, the centre being at one focus of an elliptical reflector c, a, b, the conjugate focus P being at or near ground level. A semi-spherical reflector d, e, f, also having its focus at o, has such a radius that waves falling on it are reflected back through o in phase with those falling on the elliptical mirror. As shown the waves diverge over a vertical angle g, P, k and a horizontal angle of 180 degrees. For producing an equi-signal overlapping beam, two such arrangements close together may be differently modulated and so designed that the beams overlap by, say, 5 degrees as indicated in Fig. 3, the overlap being shown shaded. With this arrangement, there is no sense ambiguity as there is no radiation within the angle 180 degrees - 185 degrees. Three such devices may be arranged to define three courses at an angle of 120 degrees, Fig. 4 (not shown).

Abstract: 1,072,421. Continuous furnaces; burners. ARTHUR G. McKEE & CO. Feb. 3, 1966 [Feb. 10, 1965], No. 4755/66. Headings F4B and F4T. Ore pellets are hardened on an endless travelling grate 3 moving between lower windboxes and a pair of upper burner hoods 5, each hood incorporating a burner nozzle 52 having internal helical ribs 54 and deflectors 58 acting on the stream of pulverulent fuel and primary air issuing from pipe 57, and windboxes 61 and 66 respectively supplying preheated secondary air and tertiary diluent air. Windbox 61 has controllable vanes 63 producing swirling motion of the secondary air through opening 51 around the burner, and angled openings 69 in windbox 66 produce an opposite swirling motion in the tertiary air which cools the gases down somewhat before passage through the pellets. A central tube 50 either acts as an igniter or introduces alternate gas or oil fuel. The windboxes below the grate 3 are associated with fans which ensure that the various gases circulate as follows. Air supplied upwardly at the discharge end of the grate cools the pellets and is then divided. Part provides the preheated air for the burners and part passes downwardly through an adjacent inner cooling section of the grate and then upwardly through a preheating section, Fig. 1 (not shown). Hot gases passing downwardly through the pellets from the burners are discharged to waste, possibly through heat recovery apparatus. In a modification, Fig. 5 (not shown), a single elongated burner casing is utilized enclosing four burner nozzles as previously described. In another modification, Figs. 6 and 7 (not shown), the travelling grate provides a preheating section only feeding pellets to a rotary furnace equipped with a a burner again of similar design. This burner has three concentric cylindrical baffles defining paths for the secondary and tertiary air. Pellets are discharged from the rotary furnace into a flat, drum-like cooler.

Title: Improvements in or relating to the production of artificial filaments or like extruded materials
IPC: D01F2/30
Filed: 1932-02-18
Abstract: Artificial filaments are stretched continuously with production, the stretching force being prevented wholly or partly from extending back to the liquid filaments at the point of extrusion by a tensioning device or devices applied initially at points which are successively brought closer to the point of extrusion.  In this manner stretching of the filaments when in a condition too weak to withstand the shock of the initial application of the tensioning means may be effected. If desired, tensioning devices more remote from the extrusion orifices may be removed after a tension device nearer to the extrusion orifices has been brought into action.  The tensioning devices may be rod or freely mounted rollers, and in the case of dry spinning, they may be disposed at intervals along the whole path of the filaments through the evaporative atmosphere or within a range where the filaments contain more than 50 per <PICT:0397509/IV/1> <PICT:0397509/IV/2> <PICT:0397509/IV/3> <PICT:0397509/IV/4> cent of solvent.  As shown in Fig. 1, filaments 14 are extruded downwardly from a nozzle 13 in a casing 10 through which passes a counter-current of evaporative medium, and pass out of the casing to a withdrawal roller 17 rotating at a greater peripheral speed than the rate of extrusion.  They are further stretched by a roller 18 and then wound by the cap spinning device 19.  Within the casing are a number of fixed rods 27 and movable rods 28, 33, the latter being operated by handles 31, 32.  When spinning is started the tension rods are in the inoperative position.  The movable rod 33 is then pushed into contact with the filaments, and the rods 28 are subsequently brought into action so as to apply the tension at points which approach successively closer to the p  point of extrusion.  As shown in Figs. 2 and 3, a number of rods are disposed on opposite sides of the filaments and pivoted so that they may be brought into contact with the filaments and constitute tensioning devices.  The rods are jointed together and are operated simultaneously by the handle 50.  They are so mounted that the rods more remote from the nozzle contact with the filaments before those nearer to the nozzle and when the rods nearest to the nozzle are in operation, those remote therefrom are moved out of contact with the filaments.  If desired, the filaments may be lubricated before coming into contact with the tensioning devices.  The stationary rods 27, shown in Fig. 1, may be hollow in construction and supplied with lubricant which passes through perforations 41 as shown in Fig. 1a and an absorbent fabric coating 42 to the filaments contacting therewith.  The device may be used in dry or wet spinning processes for the production of threads of cellulose acetate, nitrate, or other cellulose ester, ethyl cellulose or other cellulose ether, or regenerated cellulose threads from viscose, cuprammonium or cellulose nitrate solutions.
