Abstract: 1,207,003. Refining iron. DIRECTOR OF NATIONAL RESEARCH INSTITUTE FOR METALS. Aug. 13, 1968 [Aug. 14, 1967], No. 38628/68. Heading C7D. Molten metal such as pig iron is continuously refined in at least two trough type furnaces arranged in series, each furnace as shown in Fig. 1 including a flow inlet 2 for molten metal at one end and a flow outlet 3 for molten metal at the other end, a blowing zone having at least one lance 4 for feeding oxygen and slagging material, a flow zone adjacent the blowing zone in which slag and metal react while flowing concurrently to the outlet, a slag-off hole 6 and gas-offtake 7 and a skimmer 5 for separating slag and gas from the outflowing metal. Alternatively as shown in Fig. 2 the slag and metal may flow countercurrently in the flow zone the slag-off hole 6 and gass-offtake 7 being situated near the metal inlet 2. Metal may flow from one furnace to the next via an intermediate reservoir, Fig.5 (not shown). In an example using four furnaces in series, dephosphorization, silicon and manganeze removal and a minor amount of decarburization is effected in the first furnace at a temperature in the range 1300-1550 C. with addition of slag-forming material such as lime in the range 1/60 to 1/15 of the pig iron treated and with a mean residence time of molten metal in the furnace of 1 to 15 minutes. In the second furnace the major decarburization is effected at a temperature of 1550-1700 C. In the third furnace a final refining is effected and in the fourth the metal is deoxidized and its composition adjusted.

Abstract: 1,178,960. Skiving machines. FORTUNAWERKE MASCHINENFABRIK A.G. 13 Aug., 1968 [18 Aug., 1967], No. 38690/68. Heading B4B. A method of producing a finished product, such as a shoe upper, comprises feeding a workpiece 15 and a transparent or translucent pattern 13 superimposed thereon, through a skiving machine so as to split the workpiece to form a part 16 having a shape corresponding to the shape of the pattern, the pattern and the workpiece being illuminated from below as they are fed to the skiving machine. The pattern, which is made from a material having a high coefficient of friction, such as a transparent or translucent rubber is first made by superimposing a master pattern 5, Fig. 6, on a pattern blank and then feeding them through the machine so as to cut the blank to the shape of the master pattern. The cut pattern is then placed on the workpiece which is supported on a table having a transparent top 18, 19. A lamp 21 is mounted under the table so that the workpiece 15 shows up as a sharp silhouette thereby enabling the pattern to be correctly located over the workpiece. The pattern and blank are then fed to a band knife 12 via a rigid feed roller 8 and a resiliently covered roller 9.

Title: Fruit grader
IPC: B07B13/05
Filed: 1960-11-10
Abstract: 901,563. Fruit-grading machines. BARTLETT, N. M. Nov. 10, 1960, No. 38707/60. Class 117. [Also in Group XXX] A fruit-grading machine comprises a horizontal endless conveyer belt 5, a driven rotatable disc-like resilient element 8 spaced above the belt for brushing fruit of a predetermined size sideways off the belt and means to alter the fruit-carrying face of the belt from flat to concave form for changing it from being suitable for round fruit to oblong fruit. As shown, Fig. 1, there are two conveyer belts on opposite sides of a casing 2, involving two similar sets of mechanism. The belt 5 (refering to one side only) moves between the casing 2 and a side plate 6 in which are gaps 7. Each sizing disc 8 is of synthetic sponge rubber, cemented to the underside of a disc 9 which is rotatable on the lower end of a spindle 12 and has a groove in which a V-belt 20 fits, whereby drive is transmitted from a motor 18. The spindle 12 may be raised and lowered in a bracket 13 by a screw-threaded rod 14, to adjust the gap between the sizing disc 8 and the conveyer belt 5. Fruit smaller than this gap passes on to the next sizing disc which is closer to the belt, and so on. A pointer (not shown) extends from a block 16 on the spindle and indicates the size of the gap on a scale. The sizing disc and the conveyer are both inclined transversely to the direction of movement and the sizing disc is also inclined longitudinally, whereby the edge of the disc with which fruit carried by the belt first makes contact is closest to the belt and such fruit is thus brushed off immediately. The transverse inclination of the conveyer belt 5 causes fruit to wheel about its axis in approaching the sizing disc so that it is sized according to its diameter. The flat fruit-carrying face of the conveyer belt, Fig. 4, used for round fruit, is changed to the concave face, Fig. 5, used for oblong fruit, by pushing a V-shaped member 25 into an endless slit 24 in the belt, extending inwards from its edge. The member 25 is mounted on the ends of arms 26 and extends parallel to the slit edge of the belt, the arms 26 extending from a shaft 27 which may be turned by an arm 30 with a handle-and-rod member 31. Fruit brushed through a gap 7 encounters a flat circular foam-rubber covered table top 33 which is slowly rotated by a spindle which frictionally engages the edge of the table and has a pulley 37 which is driven from a motor 36. Sponge-rubber surfaced flaps 32, hinged to the casing 2, engage the fruit on the belt 5 and turn it into the required position.

Title: Process for the separation of mixtures containing cresols and xylenols
IPC: C07C37/68
Filed: 1962-10-05
Abstract: Mixtures of cresols and xylenols are separated into their individual components by alkylating the mixture with isobutene in the presence of 0.1 to 1.0% by weight of 70% perchloric acid based on the amount of the phenols to be alkylated, neutralising perchloric acid in the reaction mixture and separating the resulting perchloric acid salt therefrom, fractionally distilling the reaction product separated from perchloric acid and converting by dealkylation the butylated phenols in the individual fractions into the corresponding phenols. The invention is described by reference to the separation mixtures of m- and p-cresols and 2,4- and 2,5-xylenols. The alkylation reaction, which may be carried out at 10 DEG  to 60 DEG C., yields dibutylated products in the case of cresol mixtures and monobutylated products in the case of xylenol mixtures. Neutralisation of perchloric acid is preferably effected using gaseous ammonia but an aqueous solution of ammonia can be used. Specification 484,151 is referred to.
