Title: Oxidation of secondary butyl toluene
Inventor: O'NEILL WILLIAM ALEXANDER
IPC: C07C51/265
Filed: 1956-11-12
Abstract: In a process for the oxidation of secondary butyl toluene by means of oxygen or a molecular oxygen-containing gas, the oxidation is carried out in a carboxylic acid medium, and in the presence of bromine or a bromide and a metal oxide or salt of variable valency.  The oxidation may suitably be effected in acetic acid or benzoic acid.  As a source of metal ions and bromine one can use cobalt and/or manganese bromides.  It is also possible to employ manganese or cobalt acetates together with a substance capable of producing bromide ions under the reaction conditions, e.g. hydrogen bromide, sodium bromide or an organic bromide.  In an example, a mixture of 1 part of secondary butyl toluene (obtained by alkylating toluene with a mixture of butenee-1 and butene-2) and 5 parts of acetic acid was heated to 130 DEG C. in the presence of cobalt bromide (0.005 parts) and manganese bromide (0.005 parts); and oxygen at 3 atm. pressure was passed through the mixture for 20 hours.  The product was filtered hot to remove terephthalic acid.  The motherliquors were then subjected to fractional distillation to separate acetic, phthalic and isophthalic acids.  The combined yields of mixed phthalic acids was 91%. Specification 744,746 is referred to.

Title: Control mechanism for artificial ankle
IPC: A61F2/50
Filed: 1957-11-05
Abstract: 852,362. Artificial legs. MAUCH, H. A. Nov. 5, 1957 [Nov. 26, 1956], No. 34521/57. Class 81(2) An artificial leg comprises a shank 2 pivoted to a foot 1 for limited relative movement thereto and control means acting to limit dasiflexion of the foot relative to the shank under load whenever the longitudinal axis of the shank is in or has passed through a vertical position. The shank is pivoted to the foot about a pin 18 which carries steel brake discs 20 mounted at each end of a spacer bushing 21 and a rotatable bushing 25. The rotatable bushing supports a steel lever 26, one end of which is pivotally connected to an adjustable bracket 24 in the shank, the other end depending into a sector-shaped housing 12 which is carried by the pin and fixed in a recess 6 in the foot. The brake discs 20 project into the housing and the ends of the pin pass through holes 17 which are of larger diameter than the pin and are located in the top of the housing. Rollers 30, 31 seated on the rotatable bushing 25 are fixed to the shank 2 and project into the housing above steel balls 36 which can roll freely on the concave base 13 of the housing when the foot is not loaded. The lower end 29 of the lever tapers from front to rear and depends centrally between the balls 36. Springs 39, 40 between the foot 1 and the shank 2 bias the foot at right angles to the shank under no-load conditions. When the foot is loaded during a stride, the pin moves downwardly in the holes and the brake discs engage the housing to brake movement of the foot relative to the shank. As the shank and lever assume a vertical position under load, the lower end of the lever pivots between the balls and wedges them against the brake discs, which bear against the sides 15 and base of the housing, dasiflexion of the foot thus being limited. On releasing the load, the foot is free to pivot under gravity as limited by the springs 39 and 40. In a hydraulic form of the leg (Figs. 3 and 4 not shown), the lever is formed with a piston at the lower end which under no-load conditions is free to pivot in a sealed housing containing hydraulic fluid. On applying load, the piston bears against the bottom of the housing which restricts its movement relative to the housing. When the shank and the lever are vertical a ball which is normally free to roll on the bottom of the housing, closes an aperture through the piston thus preventing flow of fluid from one side of the piston to the other and locking the foot relative to the shank.

Title: Method of forming monoblock refractory linings for electric arc ovens
IPC: B28B21/10
Filed: 1958-10-28
Abstract: Refractory linings for electric arc ovens are moulded in a single block by arranging two cylindrical collapsible sheet metal forms concentrically so that their diameters are equal to the external and internal diameters of the desired lining and their height corresponds with the height of the lining, filling the space between them with refractory material which is then compressed and compacted, and finally collapsing and removing the metal forms after the material has set.  Preferably each of the metal forms is in the form of a cylinder with a domed end portion. Suitable refractory materials are dolomite with the addition of tar as a binder or, especially for high temperature furnaces, a mixture of magnesite and other natural earths in equal proportions.  These refractory materials may conveniently be compacted by the use of mechanical hammers.  Metal, e.g. iron, reinforcement may be incorporated comprising a series of concentric rings in different planes, U-shaped spacing cages affixing and spacing the rings, and loops attached to these rings and cages.

Filed: 1953-12-21
Abstract: 727,640. Pulse generating circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Dec. 21, 1953 [Dec. 24, 1952], No. 35494/53. Class 40(6). A high voltage pulse generator for energizing a magnetron in which an artificial line is charged from a source and discharged via a pulse transformer to which the magnetron is connected, comprises a series combination of a capacitor and a voltage-dependent resistor connected in parallel with a winding of the transformer, thus limiting the steepness of the flank of the energizing pulses. The Figure shows a circuit in which the artificial line 2 is charged from a D.C. source 1 and periodically discharged through the primary of pulse transformer 7 via cable 6 when gas-discharge tube 5 is fired. The voltage produced across the secondary of transformer 7 (Fig. 2 (a), not shown), is applied to energize magnetron 8 across which a series circuit comprising capacitor 9 and voltage-dependent resistor 10 is connected. The resistor 10 has a resistance value which decreases with an increase of voltage across it so that the build-up of voltage across the magnetron increases less rapidly than would otherwise be the case (Fig. 2 (c), not shown), and the steepness of the leading edge of the excitation pulse may thus be adjusted by proportioning of the network 9, 10. In a modification, an inductor is connected in series with the network 9, 10, thus reducing the energy loss in resistor 10. Specification 722,694 is referred to.
