Title: Improvements in or relating to process for treating a secondary alkylbenzene
IPC: C07C6/12
Filed: 1954-10-25
Abstract: A disproportionation process comprises contacting di-isopropyl benzene or di-secondary butyl benzene under substantially anhydrous conditions and in the substantial absence of hydrocarbons which are not inert to the HF-BF3 agent and do react with the secondary alkyl benzene charged and benzene, with between 1 and 5 mols. of BF3 and between 3 and 50 mols. of liquid HF per mol. of secondary alkylbenzene, at a temperature between -20 DEG  C. and +60 DEG  C. for a time sufficiently long to permit a disproportionation reaction to take place and recovering from an acid phase a reaction product mixture in which the tri-secondary alkyl benzene is the predominant poly-secondary alkyl benzene product.  By a corresponding process tetraalkylbenzenes are obtained from tri-alkyl benzenes.  The feed may also contain hydrocarbons which are inert under the conditions of the process, these may be isopentane, butane or hexane.  By a similar process a di-secondary alkylbenzene containing a mixture of the meta isomer and a substantial amount of at least one other isomer is isomerized to the meta isomer.  By adding benzene to the mix the isomerization process may advantageously be carried out at -5 DEG  C. The product is preferably separated by adding the acid phase to crushed ice and subsequently purifying the supernatant layer.

Title: Improvements relating to the shaping of metal tubing
IPC: B21D7/06
Filed: 1955-05-11
Abstract: 808,809. Making musical instruments; bending tubes; stamping. DRAPER, F. C., and BOOSEY & HAWKES Ltd. April 30, 1956 [May 11, 1955], No. 13665/55. Classes 83 (2) and 83 (4). A method of forming a bend in a length of tubing comprises subjecting the tubing to tension and forcing it into contact with a former having the required curvature in the plane of bending and shaped to support the tubing around approximately half its periphery, the tension being maintained at a value such as to avoid compressive stresses in the inner surfaces of the bend which would produce cockling, and the outer surface of the bend being allowed to collapse inwardly under the tensile forces acting on it, after which the collapsed bent tubing is expanded to its required final shape under the action of fluid pressure while contained in a die. A tube 20, for example a tapered tube to form part of a wind instrument, is held under tension between collets 26, 27 on hydraulic rams in cylinders 28, 29. A former 23 is then adjusted into contact with the tubing 20 by an hydraulic cylinder 25 and a member 45 is moved, by hydraulic means 46, into position to co-operate with the former 23 to form extensions 47 of the groove of the former to prevent lateral distortion of the tube. The cylinders 28, 29 and their collets 26, 27 holding the ends of the tube 20 are then swung along guide slots 32, 33 by pivoted hydraulic cylinders 35, 36 so as to wrap the tube 20, under tension, around the former 23, the outer wall of the tube collapsing during such bending. When the bending is complete the member 45 is withdrawn and die parts 50, 51 are moved inwardly by hydraulic cylinders 52, 53 to constitute with the former 23 a complete die for the expansion of the collapsed bent tube. Pressure in the cylinders 28, 29 is then released and, with the tube 20 still held in the collets 26, 27, hydraulic pressure is applied to the interior thereof, by a connection 55 leading to the collet 26, to expand the collapsed tube. In another embodiment a tube 10 is secured at 11 to a former 12 on a rotary capstan 13 and the other end is secured by a collet 14 to a ram in an hydraulic cylinder 15 to maintain a constant tension in the tube during bending. The groove in the former has divergent wall extensions. The tube may be annealed before bending. Specification 701,112 is referred to.

[Class 74 (ii).] Ordinary as distinguished from warp-knitted fabric is made ladder-proof or ladder-resisting by the inclusion of locked or tied loops formed out of the common ground yarn. The fabric is also shaped in course of manufacture. Plural latch needles are preferably used and these are elevated to a higher position at alternate courses to enable the loops b to clear the lower latches and subsequently envelop a yarn c laid between the latches. A number of selvaged blanks of the fabric described above may be made simultaneously on circular machines of the type described in Specification 288,350, [Class 74 (ii), Knitting & c.]. The fabric can also be made on a circular machine with a reciprocating cam envelope the cam 20, Fig. 8, of which is vertically displaceable. In the lowered position of this cam ordinary stitches are produced. If the cam 20 and other displaceable elements are adjusted between each course ordinary and locked stitches are produced alternately. The adjustment is effected by a horiz ontally slidable member 27 under pattern control. The non-ladder fabric can be produced on a flat machine by employing two differently designed cams for imparting different degrees of motion to the needle bar, so that the yarn can be fed either into the needle hooks or between the latches. The hooks are made somewhat springy so that transfer points may be used on them.

Abstract: 585,053. Impedance networks. CLIFFORD, F. G. July 27, 1944, No. 14323. [Class 40 (iii)] A band-pass filter with variable band-width but constant mid-band frequency comprises a pair of tuned transformers coupled in cascade, the band-width being variable by adjustment of the terminating resistances or of the coupling coefficients. The filter shown in Fig. 1 is so designed that L1C1=L2C3=L2C2(1 - k<2>), where k is the coupling coefficient, and R1 /R2= L1/L3. The attenuation characteristic is single-humped and narrow as at A, Fig. 2, when the resistances are small, single-humped and broad as at B when the resistances have the critical value, and treble-humped With increasing width as at C, D when the resistances are increased. For the purpose of varying the band-width, the resistances may be variable and ganged, or the coefficients of coupling of the transformers may be varied in a constant ratio by electromagnetic screening or by relative movement of the windings. In a modification, Fig. 3 (not shown), the intermediate circuit L2C2 is omitted and the inductances L1, L3, while decoupled from one another, are coupled to a third inductance tuned with a condenser. In a further modification, Fig. 4 (not shown), the end meshes are series-resonant and the intermediate mesh is shunt-resonant.
