Title: Process for the manufacture of paper pulp and other products from the fleshy parts of sisal and similar plants
IPC: C14C3/24
Filed: 1942-03-16
Abstract: The fleshy matter remaining after removal of the fibre from sisal and like plants, e.g. Agave Sisalana and Phormium Tenax, by decortication is subjected to a heat treatment under pressure in autoclaves or digesters with sulphur dioxide, sulphurous acid, or soluble sulphites or bisulphites in acid solutions, so as to obtain pulp suitable for use in the production of paper, cardboard, or building boards or like materials.  The sulphite liquor remaining after the treatment is utilized as a foam stabilizer in making fire-extinguishing foams or in making foamy compositions for use as visible or luminous sea-surface spot indicators, or is utilized as a tanning material in admixture with materials such as quebracho, mimosa, chestnut, valonia or myrabolams.  Prior to the sulphite digestion, the sisal or like fleshy material may be subjected to extraction with water to remove sugars, glucosides and other water-soluble substances, and then with acids to extract pectin and/or with alkalies, e.g. carbonates, to extract pectic salts.  The fresh sulphite liquor for the sulphite digestion may be obtained by burning sulphur or pyrites and passing the gases through a water tower containing limestone or dolomite. Wetting agents such as sulphonated oils may be added to the treating liquid to facilitate impregnation. When the digestion has proceeded to the desired extent, the sulphite liquor containing lignin sulphonic acid is run off from the pulp.  Specifications 532,877, [Group V], 538,271 and 556,808, [Group V], are referred to.

In making a soldering iron bit a core of copper is inserted in a cover of metal having greater corrosion and oxidation resistance than copper and is secured therein and the assembly is then forged to shape. A conical cover 1 of carbon steel, carbon content 0À3-1À0%, is produced by pressing, drawing or forming in a lathe steel sheet, or steel tubing or by turning a steel bar. A copper core 2 is inserted in the cover 1 under great pressure in a press &c., the assembly is heated to 600-1400‹ C., preferably about 1000‹ C. and solder metal and flux are introduced into an aperture provided at the pointed end of the cover so that the cover is hard soldered to'the end of the core. While heated the assembly is forged to wedge shape and after cooling the pointed end is ground flat. The cover is then welded at the point to cover the opening in the cover and the end is ground to wedge form. The cover is hardened by heating in a carbonizing flame and cooling in oil or water. A flange 5 is pushed on to the cylindrical part 4 of the core and a washer 6 is hard soldered to the end of the core. The cover after assembly may be chromium plated except at its pointed end.

Abstract: 999,688. Frequency changing. MASCHINENFABRIK OERLIKON. Feb. 2, 1962 [Feb. 3, 1961], No. 4161/62. Heading H2F. In a frequency changing arrangement between a high-frequency network 1 and a lowfrequency network 11, which is hereafter described in terms of a high-to-low frequency change although reverse action is also contemplated, the network 1 is connected to a primary winding 1 of a first transformer having two centre-tapped secondary windings 1<SP>1</SP>, 1<SP>11</SP> whose ends are connected to the anodes of SCR's whose common anode junction is connected via a choke 7 to the centre-tap of a winding 6<SP>1</SP>, this winding having ends connected to the centre taps of windings 1<SP>1</SP> and 1<SP>11</SP> and being coupled with a winding 6<SP>11</SP> connected to the network II. Control signals for the rectifiers are derived via unit 8 from both high and low frequency networks. In operation rectifiers 2 and 3 operate at the high frequency to provide a positive halfcycle of the low frequency, after which rectifiers 4 and 5 operate to provide the negative halfcycle and so on. Low-frequency commutation is effected by the following method :-Assume that 4 and 5 are operating and commutation so that 2 and 3 are operating is to take place in a L.F. half-cycle when the lower ends of 1<SP>1</SP> and 1<SP>11</SP> are positive. Rectifier 5 is not fired to conduct at the beginning of this half-cycle and the current flowing through 4 continues to flow by virtue of the choke 7 until rectifier 3 is fired to effect the commutation.
