Title: Aromatic hydrocarbon extraction process
IPC: C10G21/00
Filed: 1965-02-10
Abstract: In a process wherein the overall effect is to separate by solvent extraction alkyl naphthalenes from the remaining mainly aliphatic constituents of cycle oil, two extraction zones are used each containing the same solvent which is a mixture of dimethylformamide and water containing 5 to 18% preferably about 10% water.  As shown, the cycle oil is fed to extraction zone 2 through line 7, the feed to extraction zone 1 along line 3 being a displacer oil, i.e. a mixture of xylenes and non-aromatic hydrocarbons, e.g. C6 to C8 paraffins, the mixture preferably having a boiling range at least 56 DEG  C. lower than the cycle oil.  The extract from extraction zone 2 contains the alkyl naphthalenes and is passed via line 10 to extraction zone 1 where the xylenes of the displacer oil displace the alkyl naphthalenes into the raffinate.  The extract from extraction zone 1 is passed via line 6 to extraction zone 2 where the alkyl naphthalenes displace the xylenes into the raffinate. <PICT:1104513/C4-C5/1> The raffinate from extraction zone 1 is passed via line 5 to distillation zone 3 where the alkyl naphthalenes are separated and removed, the other constituents being recycled to extraction zone 1 via line 31.  The raffinate from extraction zone 2 is passed to distillation zone 4 where the non-aromatic constituents of the cycle oil are separated and removed, the remaining constituents, mainly xylenes and some solvent, are recycled to extraction zone 1 through line 31.

Title: Improvements in or relating to Stitching Apparatus.
IPC: B29D30/28
Filed: 1969-02-04
Abstract: 1,193,054. Stitching apparatus for tyre building. NATIONAL-STANDARD CO. 4 Feb., 1969 [17 April, 1968], No. 6011/69. Heading B7C. Apparatus for stitching a tyre tread to a tyre carcass comprises a chuck arrangement 3 mounted on a pivoted box member 10 to enable a carcass of a diameter from a predetermined range which is rotatably mounted on the chuck to be positioned with its periphery at the, discharge end of a tread supply means 170, and wherein an endless belt 20 passing round rollers 23, 24, 25 has a run of double concave configuration between rollers 24, 25 which on pivoting of the belt frame 22 is adapted to contact the tread thereby stitching it to the carcass, the length of this run which contacts the tread being determined by a roller 90 slidable in slots 96 in consequence of the tyre diameter. The frame 22 is pivoted on two pairs of arms 35, 36 and is movable to and from the carcass by a ram 165. The position of the roller 90 depends on the amount of this pivoting the roller being connected to chains 100 having their free ends within channel members 104. On pivoting of frame 22 the chain ends within members 104 contact stop means 106 and further pivoting causes the roller 90 to move up the slots 96. The run of the belt on contacting the tread takes on a double concave configuration and tread wing rollers 108 and a crown roller 107 exert pressure on the tread to carry out the stitching. The roller 107 is pivotally connected by linkwork 116 to frame 22 and an air spring 112 connected with this linkwork in the source of the crown roller tread pressure. The tread wing rollers 108 are pivoted within U-members 124 which are connected with a ram 146 which is the source of the wing rollers tread pressure. A motor 15 for rotating the chuck is suspended from box member 10 and drives through a belt 16 and reduction gearing 17. The member 10 is pivoted by having a connection 84 with a screw shaft 60 manually operable by handle- 64. The shaft may be clamped in a set position by a thrust bearing arrangement 69. Micro switches and timers may be utilized to control a cycle of operation of the apparatus.

In a magnetic recording apparatus, a wide magnetic band 1 is drawn from a spool 21 by two feed rollers 8, 9 over an unreeling controller 60, a flanged guide roller 7, and an exploration table 3, the band then passing over a take-up controller 100 to a take-up spool 51. The feed roller 8 is mounted on a shaft 80 which is driven at constant speed by a motor 11 via gearwheels 110, 111, 114. The unreeling controller 60 comprises a pulley 6 on a spring loaded arm 61 which closes a switch 66 when the tension in the band increases, so that a magnetic coupling 112, Fig. 2, is brought into operation to drive the shaft 20, on which the spool 21 is mounted, in an unwinding direction. A similar device 100 opens a switch 106 when tension increases, so that a magnetic coupling 116 is de-energized to stop rotation of the take-up spool 51. A spring-loaded friction arm 53 and pad 52 ensures close winding on the spool 51, while a metallized strip 57 earths static charges arising from the friction caused by the pad 52. The transducer 4 is made to traverse the band 1 in the manner described in Specification 674,570.

Filed: 1928-02-29
Abstract: 299,441. Sprucolite Corporation, (Assignees of Ollesheimer, L. J.). Oct. 28, 1927, [Convention date]. Plywood sheets. - In the production of laminated products by the uniting under pressure of layers of fibrous materials such as wood and a water-containing binder, the moisture content is reduced at some stage of the process to such an extent that the. final moisture content, including that of the binder, is less than that of normally kiln-dried wood to minimize the distortion of articles made therefrom produced by evaporation of moisture owing to a hot or cold climate. For example, in making a product suitable for the manufacture of gears, pulleys, &c. by glueing thin planks of wood with the grain crossing, under pressure, the drying of the wood is continued until there is not more than about 2 per cent of moisture present, care being taken not to close the pores of the wood in the process. The boards are then coated with a binder, for instance, a casein glue, and are pressed lightly until an initial set has taken place, when the pressure is increased. The drying step may be carried out after the compressed block is made.
