IPC: G21F5/005
Filed: 1967-09-08
Abstract: 1,196,269. Shielded containers. NATIONAL LEAD CO. 8 Sept., 1967 [9 Sept., 1966], No. 41161/67. Heading B4Q. A shipping container for radio-active material has a non-circular cross-section cavity 137, shown as a square cross-section, defined by stainless steel plates 130, 132, 134, 136 disposed within a stainless steel cylindrical inner shell 94. The space between the cavity 137 and the shell 94 is filled with primary shielding material consisting of corner shield means 140 and shielding 142. To unify the shielding effect the corner shield means 140 are of a more dense material than that of the shielding 142 and, as shown, the means 140 are of cast uranium and the shielding 142 is of lead. Safety shielding 96 is provided in the space between the shell 94 and an outer shell 22 of stainless steel having cooling fins 28. The shielding 96 comprises a series of spaced cylindrical sheets of steel with the intervening spaces filled with a shielding material having a lower melting point than that of the primary shielding, the preferred material being a lead antimony alloy. Normally, the series of spaced cylindrical sheets serves to improve the thermal conduction to facilitate removal of the radio-active decay heat. In the event of an external fire, however, the lead antimony alloy escapes through relief plug means 100 and the reflecting surfaces of the series of cylindrical sheets forms a barrier to the radiant heat. Each end of the container is closed by closure means, one such closure 240 being shown in Fig. 6. This closure comprises lead shielding 238 and safety shielding 244 similar to the shielding 96. A relief valve 270 is connected through a conduit 262, 260 to the cavity 137.

Abstract: 1,245,475. Extracting solids. ZAKLADY WLOKIEN SZTUOZYNCH "STILON". 4 Sept., 1968, No. 42013/68. Heading B1Q. [Also in Division C3] In a process for extracting granular material with liquid extractant the granules are placed in closed vessels in a series of vessels interconnected by pipes, liquid is introduced to a first vessel of the series to cause overflow therefrom into the subsequent vessels and cause discharge of a concentrated liquor from a downstream vessel, liquid being introduced into subsequent vessels of the series in turn to repeat the discharge of concentrated liquor from downstream vessels and leave in the vessels extracted granules for unloading. In the embodiment shown (Fig. 1) a series of vessels 1 to 8 are arranged in a circle, each containing polycaproamide granules. Water flows into the bottom of vessel 1 and extracts water-soluble substances from the granules therein, the liquor passing from the top of vessel 1 through a heater into the top of vessel 2 to displace liquor from the bottom of vessel 2 into subsequent vessels 3, 4, 5 and 6 into the downstream vessel 7 containing polycaproamide and concentrated liquor from a storage vessel 9. As the liquor from vessels 1 to 6 passes into vessel 7 concentrated liquor is discharged therefrom into storage vessel 9. After introducing the fresh water into vessel 1 it is disconnected and vessel 8 is connected, fresh water being fed to vessel 2, vessel 1 being unloaded and recharged with unextracted granules. The process is then repeated.

Abstract: 1,115,529. Shearing. SKODA OBOROVY PODNIK. 5 Oct., 1965 [10 Oct., 1964], No. 42171/65. Heading B3W. In a pendulum shear the upper and lower blades are actuated by a main crank-shaft 2 and the swinging movement of the frame is produced by an auxiliary crank-shaft 4 which is connected to the lower part of the frame by rods 3. A gear-wheel 9 is secured to the main crank-shaft and meshes with a gear-wheel 10 which is free to rotate on the auxiliary crankshaft 4 but is secured to a bevel wheel 6 which is part of a differential mechanism. A pair of planet wheels 8 are mounted in a carrier 5 which is freely rotatable on the auxiliary crankshaft 4 and which can be rotated through 45 degrees on either side of a basic position by a screw mechanism 12 driven by a motor 13. The planet wheels mesh with the bevel wheel 6 and also with a second bevel wheel 7 which is secured to the auxiliary crank-shaft 4. Rotation of the screw alters the phase angle between the main and auxiliary crank-shafts and thus the amplitude of oscillation of the cutter frame. The adjustment can be made while the machine is running. Alternatively, Fig. 6 (not shown), the main and auxiliary crank-shafts are directly gear-coupled and rotate in opposite directions. The toothed rim of the gear-wheel on the auxiliary shaft is rotatable relative to the hub of the wheel, by means of a screw mechanism, in order to adjust the phase angle between the crank-shafts. The machine must be stopped in order to make this adjustment.
