Patent FI-20000453-A (FI)
Inventor: ROUSU PASI
IPC: C05F7/02
Filed: 2000-02-28
Abstract: The invention relates to a process for treating bleaching liquors from pulping processes based on organic acids. The process is characterized in that inorganic acid, such as nitric acid, phosphoric acid and/or sulphuric acid, is added into a bleaching liquor obtained from the bleaching or a stage closely associated with bleaching, whereby organic acids contained in the bleaching liquor are released into the bleaching liquor. The organic acids are then separated from the bleaching liquor and recycled to the cooking stage to be used as cooking chemicals. The nitrogen-, phosphor- and/or sulphur-containing product thereby produced, from which organic acids have been separated, is recovered to be used as a fertilizer or as raw material for a fertilizer.

Abstract: 1,051,407. Armour-piercing projectiles. DIRECTOR GENERAL OF FÍRSVARETS FABRIKSSTYRELSE. June 30, 1964, No. 26957/64. Heading F3A. An armour piercing projectile is provided with a forward charge 5 and a rear charge 1 arranged for successive detonation by fuzes 7 and 3 respectively, the forward charge 5 being housed in a casing 8 which tapers to a point so that the gases produced by this charge expand away from the fuze 3 and charge 1, thus avoidng premature ignition of charge 1 and allowing charge 1 to pass through the debris from charge 5 and detonate within the target. Hollow charges may be used for both charges, the forward charge 5 being provided with a liner 6, which has an annular groove the walls of which are so inclined that the hot gases from charge 1 move forward in an annulus and cut a hole in the target large enough for the body of the projectile to pass through. A tapered sleeve 4 connects the two charges and the missile may be rocket propelled. Fig. 5 shows a modification in which the space between a conical ballistic cap carrying the fuze 3 and the charge 1 is filled with a brittle foamed plastics 22 surrounded by the sleeve 4, which is made of thin aluminium. The charges are detonated by means of capacitors 9, 10 charged when the missile is fired. One pole of each capacitor is electrically connected to the conductive casing of the missile. The second pole of capacitor 9 is connected in circuit with an igniter 12 by an insulated conductor 11 and thence to a ring 13 supported in the ballistic cap 15 by an insulating ring 14. Similarly, the second pole of capacitor 10 is connected via an igniter 16 and an insulated conductor 17 to a contact rod 18 mounted by means of insulation 19 in the conductive nose 20 of the metal cap 21. When the projectile strikes a target, the cap 15 is crushed against the ring 13 and so completes the circuit through the igniter 12 and sets off the explosive charge 5. This charge cuts into a hole in the outer armouring through which the second charge passes and on impact of the rod against a surface the second circuit is completed to fire the charge 1. Modified forms of the liner 6 are shown, including one which is perforated centrally to form a flash passage. The liner 6 may be replaced by a cross-shaped member with grooves arms and a central conical portion, designed to make four cuts in the armouring.

In a ball-point pen wherein the pen 14, Fig. 1, can be projected to writing position against the action of a retracting spring 13 by depression of a push button 3, the pen is held in projected or retracted positions by the engagement of an inwardly projecting nose 5<SP>1</SP> on a washer 5, rotatably seated in a recess 12 in the pen barrel, with a groove 4 on the button comprising a groove part running lengthwise of the pen and extending into a circumferential or part circumferential section having inclined surfaces. The part circumferential section of the groove may be approximately heart-shaped (Fig. 2, not shown) or formed as shown in Fig. 7 to extend around the button, and communicating with two diametrically-opposite lengthwise sections 29<SP>11</SP>. The recess 12 may be formed between a shoulder 10 on the part 8 of the barrel 1 and a sleeve 9 screwed into the barrel. In another construction (Fig. 3, not shown), the recess 12 is formed between the inner end of barrel part 1 and a shoulder on part 8. In this case, the button has a radial projection (21) which during assembly is snapped past the nose 5<SP>1</SP> of the washer which is of the split washer type. In Fig. 8, the button 29 has a stop collar 28<SP>1</SP> engaging the inner end of barrel part 33 corresponding to part 8, Fig. 1. The edges of the circumferential section of the groove are undulating and arranged so that when the button 29 is first pressed inwardly, the nose 5<SP>1</SP> is moved into alignment with a depression 31 to hold the pen in projected position, and after a second operation of the button, the nose 5<SP>1</SP> is moved into alignment with the lengthwise part of the groove so that the retracting spring moves the pen to retracted position. The heart-shaped groove acts in a similar manner. The stop collar 28<SP>1</SP> may be detachable from the button, Fig. 9 (not shown) or may be replaced by a radially projecting spring ring insertable into a groove in the inner end of the button, Fig. 10 (not shown). Multiple pens.-The arrangement may be used in an instrument wherein the inner end 49 of the button 47 carries a pendulum-like member 52 which can be set so that depression of the button causes projection of one of a number of ball pens for writing with differently coloured inks. As before, a nose 26 on a split spring washer 25 engages a groove 4 in the button, but a stop washer 56 on the button engages the inner end of the barrel part 53 corresponding to part 8, Fig. 1.

Abstract: 1,250,158. Concentration of liquors by evaporation. PARKSON INDUSTRIAL EQUIPMENT CO. Ltd. 11 Dec., 1968 [12 Dec., 1967], No. 56450/67. Heading B1B. [Also in Division G3] In a system in which liquid is continuously re-circulated at constant velocity through an evaporator and a separator which removes vapour, the pressure upstream of the evaporator automatically controls the rate of withdrawal of liquid from the system. As shown, a feed pump 1 supplies dilute liquor to an evaporator 2 from the output of which vapour is removed for supply to a condenser by a separator 3. More concentrated liquor is returned from separator 3 to evaporator 2 by a pump 5 and'the viscosity of this liquor is measured by a pressure detector 6 which produces a pneumatic signal for comparison at 7 with a signal representing desired viscosity. Any difference is effective to control a fluid-pressure servomotor 8 which then adjusts the speed of a pump 9 withdrawing concentrated liquor from the system until the desired concentration is restored. Pump 9 may not start until the concentration approaches the desired value. Pressure detector 6 may alternatively produce a voltage controlling the speed of pump 9, The level of concentrated liquor from separator 3 is maintained constant by a signal from a level detector 10 which controls a servomotor 1a adjusting the speed of feed pump.
