Patent FI-910601-A (FI)
Inventor: HRUSCHKA ANTON
IPC: D06L4/70
Filed: 1991-02-07
Abstract: The process comprises three stages, namely an oxygen bleach which is optionally combined with a hydrogen peroxide bleach (EOP stage), an ozone bleach (Z stage) and a peroxide bleach (P stage). According to the invention, the residual oxygen content of the exit air from the Z stage is completely reacted in the EOP stage, and the effluent of the Z stage is used for dilution between the EOP and Z stages and/or for ash removal from the pulp after bleaching. It is advantageous in this case to control the temperature, the NaOH supply and the O2/H2O2 ratio in the EOP stage, so that the oxygen consumption at a constant conversion is adjusted to the residual oxygen content of the exit air from the Z stage.

Abstract: In the case of a grit spreading apparatus for winter service in which spreading material is fed from a continuous conveyor into a fall pipe (3) and via an inclined chute (15) to a specific point on a scatter plate (17), which rotates about an essentially vertical axis (18) and which is arranged eccentrically in relation to the fall pipe (3) and is swivel-mounted about the vertical axis (19) of the fall pipe (3) for transverse displacement of the scattering pattern in relation to the longitudinal centre axis of the spreading apparatus (1), the spreading material is centrifugally scattered over varying distances depending on the speed of rotation. In order to improve the distribution of spreading material and in order to achieve an adequate transverse displacement of the scattering pattern within a limited overall swivel angle ( beta ), the scatter plate (17) is rigidly arranged centrally at the bottom end (11) of a guide pipe (9), which runs sloping rearwards from the top at an angle of inclination ( alpha ) of at least 20 DEG  to the vertical (10) and which is pivotally mounted at its upper end by means of a short bearing connection (8) on a fall pipe connection (4) arranged below the continuous conveyor and can be brought by remote control into different swivel angle positions ( beta ) with the chute (15). <IMAGE>

Title: Improvement in combined weaving and knitting looms
IPC: D04B39/00
Filed: 1934-01-10
Abstract: 428,102. Combined weaving and knitting machines. CROMPTON, G., 60, East 42nd Street, New York, U.S.A. Jan. 10, 1934, No. 1004. Convention date, Jan. 30, 1933. [Classes 142 (ii) and 142 (iii)] [See also Group VIII] In a machine for making fabric having woven and knitted portions, shuttles not only supply the weft for the woven portions, but also constitute yarn guides or carriers for supplying yarn to the knitting needles. The loom parts generally are of the type usually employed in forming narrow fabrics, and the knitting mechanism is of the straight-bar, full-fashioned type. The shuttles 125 are supported by a stationary lay 110 and are so controlled that sometimes they move the distance between adjacent blocks 113, 114, as in forming a selvedge, and at other times move through two weaving spaces and the intervening knitting space. A slidable member 130 is actuated to drive pinions 118 engaging rack teeth 126 on the underside of the shuttles 125. To prevent loose ends at the selvedges, means are provided for rewinding the yarn upon the bobbins 342 carried by the shuttles. Holes or slots are provided in one flange of a bobbin 342 to receive pins 343 on a member 345. A spring 348 presses the member 345 so that the pins 343 engage the holes or slots, and a second spring 350 controlling the member 345 tends to be wound up as the yarn is drawn from the bobbin. When tension on the yarn is released, the spring 350 causes the bobbin to rewind some of the yarn. Piping may be located in the top part of the lay 110, with orifices in front of the blocks 113, 114 to direct steam or humid air upwardly against the bobbins 342. To enable the take - up mechanism to take up double the amount of fabric for certain picks, the cam 64, Fig. 9, has actuating portions 80-82, the portion 80 of which has twice the displacement of the other portions, so that the pawl 69 moves the ratchet wheel 68 a distance equal to two teeth. Each sinker 201 has a tail piece 204 by which it is held magnetically in loop sinking position, and a tail piece 205 by means of which it is reset. The tail piece 204 is engaged by the poles of an electromagnet which is energized as the slur cocks begin to move.

Title: Purification of methylnaphthalenes
Inventor: HINEGARDNER WILBIE SCOTT
IPC: C07C7/00
Filed: 1956-01-16
Abstract: Methylnaphthalenes are purified by treatment with an aliphatic peracid, preferably formed in situ, in the liquid phase, and the impurities attacked are separated, e.g. by distillation or the use of a selective solvent or selective adsorbent (such as activated alumina).  The preferred peracids are C1-C4, particularly performic, acids in an amount from 2-25 per cent by weight based on the methylnaphthalene, the process being carried out at a temperature between 20 DEG  and 60 DEG  C. with stirring.  The impurities so removed are those which are objectionable in the process for producing hydrogen peroxide involving alternately hydrogenating and oxygenating a solution of an alkylanthraquinone and/or a tetrahydroalkylanthraquinone intermediate, wherein methylnaphthalenes are employed as a solvent for the oxidized intermediate.  In an example commercial methylnaphthalene was purified by stirring with formic acid and hydrogen peroxide for 3 hours at 32 DEG  to 40 DEG C. and the product after extraction with aqueous alkali was fractionally distilled; in a further example the product is purified by passing through an activated alumina column.
