Title: Improvements in or relating to method and apparatus for radially contracting tubular metal bodies
IPC: B21D26/02
Filed: 1942-04-02
Abstract: 556,471. Stamping. UNITED STATES PIPE & FOUNDRY CO. April 2, 1942, No. 4414. Convention date, June 21, 1941. [Classes 83 (ii) and 83 (iv)] Tubes are contracted on to a mandrel at the same time becoming elongated, by the application of fluid pressure to the exterior. The process is particularly applicable for reconditioning moulds for the centrifugal casting of pipes. A substantial chamber 10 with a head 16 has the end closed by a steel plate 30 with a heavy backing plate 31 held on by bolts that do not extend into the head as far as the part that is subjected to the fluid pressure to avoid weakening the section. The chamber is bored to take the mould 13 with slight clearance and is contained in the head to take the socket end. A spacing ring 22 supports a U-section leather packing ring 21 with a backing ring 20 engaging the flange 19 of the mould that fits the bore. The mandrel 12 has an integral or inserted screw 25 on which is mounted a separate section 24 for the socket clamped in place by a nut 26. One or more filling blocks 28, 29 are provided. - The parts 24, 28 and 29 are tapped for eye-bolts for use in handling. The spigot end of the mould is spaced from the mandrel by a rigid sleeve 34 tapered at 35 so that when the mould is contracted it will not form a shoulder at the end of the sleeve. The sleeve is flanged at 26 for clamping in place by a two part ring flanged at 37, 39, this latter flange engaging a groove in the mould and fitting the bore in the chamber. The parts are dowelled and held together by a spring ring 43 in a groove 44, and the end is bevelled at 48 to facilitate introduction into the bore. Seal against fluid pressure is effected by a steel ring 45, a fibre or tin-lead alloy ring 46 and U-section leather ring 47. The fluid pressure admitted at 49 acting on these parts tends to elongate the mould and the mandrel is lubricated to facilitate the sliding of the sleeve 34. Specifications 334,634, 334,960, [both in Class 83 (ii)], 350,336 and 352,824 are referred to.

Abstract: 668,088. Hypodermic syringes. PEHACZEK, A. J. Feb. 16, 1950 [Feb. 19, 1949], No. 4590/49. Class 81 (ii). Surgical injection apparatus comprises means for attaching a syringe holder to a limb of a patient, spring means for urging the syringe towards a needle guide, carried by the attachment means, and one or more spring catches for holding the syringe in the retracted position. The syringe 72, Fig. 1, is carried in a cradle 70 which slides on parallel tubular members 69 and is urged in a downward direction by springs 81. When in the raised position, the cradle 70 is retained by catches 87 engaging in notches in rods 83 attached to it. The catches are released by pressure on projections 85 and movement of the syringe, after penetration of the skin, may be arrested by a second pair of catches which engage the notches in the rods 83 after a predetermined travel. The syringe carrier is attached by limbs 76 to a base plate 30, Fig. 8, these engaging lugs 35 thereon, and its angular disposition is set by an adjustable stop 31. The plate 30 is secured to the patient by a strap 33, and it has attaching means 37 for holding a needle guide comprising a bridge piece with a tapered aperture or slot for directing and holding the needle in its travel. In an alternative form of baseplate, see Fig. 12, hooks 45 are provided which hold the syringe parallel with it. In this case a clamp 47 holds the needle guide and pressure member perpendicular to the base plate. The clamp may alternatively hold a plate having a funnel-shaped needle guide directed at an angle to the baseplate, so that the needle may pierce the skin at an angle, as in the first example. As an optional addition, a plunger actuating device may be attached to the bosses 80, Fig. 1, and may be of the form shown in Fig. 21. Slotted tubular members 92 are attached to the bosses referred to and contain springs 93 which press down on a plate 94, slidable on the tubes and carrying a spring-loaded buffer 99 to engage the syringe plunger. Rods 95, attached to the plate 94, slide in parallel guide tubes 96 and have notches which are engaged by latches to retain the arrangement with the operating spring compressed, these latches being released when required by pressure on projecting buttons 98. In a modified form a single central actuating spring is used and the rods 95 have a series of notches so that the extent of travel may be controlled. In addition, the buffer may have a threaded extension to enable it to be brought into contact with the head of the plunger before release.
Patent GB-585527-A (GB)
Title: Improvements in or relating to the oxidation of mesityl oxide
IPC: C07C51/25
Filed: 1945-02-26
Abstract: Alpha-methyl-beta-acetyl acrylic acid is produced by subjecting mesityl oxide, in the liquid phase, to oxidation by intimate contact with molecular oxygen in the presence of an oxidation catalyst. Suitable catalysts are manganese, nickel, copper, cobalt and vanadium, for example, in the form of their organic salts.  The reaction is preferably carried out at between 70 DEG  C. and 120 DEG C. and a diluent, e.g. a liquid aliphatic acid or its alkyl ester may be used.  It is desirable to separate the alpha-methyl-beta-acetyl acrylic acid as rapidly as possible by directly distilling the reaction mixture at reduced pressure and then fractionating the distillate at reduced pressure.  It is also advantageous to oxidise the mesityl oxide to an extent not exceeding 50 per cent by weight of that present in the initial reaction mixture.  In an example, the catalyst is a mixture of cobalt acetate and copper acetate and acetic acid is used as diluent.  Oxygen is fed to the mixture at such a rate that the effluent gas contains at least 50 per cent by volume of free oxygen.  Fractionation yields alpha-methyl-beta-acetyl acrylic acid and other oxygenated products of unknown constitution.
