[Also in Division F2] A flange joint for interconnecting sections of the wall 3 of a spherical or cylindrical pressure vessel comprises, as shown in Fig. 9, two flanges 1, 2 perpendicular to the respective wall sections, which flanges are held together by bolts 6 and arranged to directly contact each other at the end portions at that side of the wall 3 where the higher pressure prevails, the remaining portions being interspaced. The axial distance between the two flange edges at that side of the wall 3 where the lower pressure prevails is selected in such a manner in relation to the pressure difference across the wall 3 that upon completed tightening of the bolts 6, the flanges 1, 2 contact each other at their last-mentioned edges via a spacer 9 in such a relative position that, in each junction between the wall 3 and a flange, the deformation of the flange caused by the tightened bolts generates a mechanical stress state the axial bending component of which is opposite to the corresponding component of the stress state generated in each junction by the pressure difference across the wall 3. The spacer 9 is preferably constituted by a metal ring. In alternative embodiments, the flanges have integral projections which engage each other directly without an intervening spacer upon completed tightening of the bolts, or the two surfaces of the flanges facing each other diverge in the outward radial direction.

[Also in Division G3] A pump or motor comprises rotary cylinder blocks 53, 54, Fig. 1, coupled by drive flanges 55, 56 to shaft 29 and engaging a ported valve member 39 and pistons 66 having slippers 75 engaging concave cam faces 77 of cam members 78, 79 which impart two strokes per revolution to ,the pistons. Convex cam members 80, 81, located by pins 86 and sleeves 90, hold slippers 75 against cam members 78, 79. Output is controlled by rotating the cam members 78, 79 in opposite directions so that the respective cylinder blocks are out of phase, rotation through 45 degrees reducing the output to zero. As a pump, the output pressure is automatically maintained at a predetermined level by a valve 28, Fig. 2, having a valve member 116 subjected to the output pressure from port 46, and loaded by an adjustable spring 124. Valve member 116 controls the supply of output pressure to two piston motors which act to rotate cam member 78, Fig. 7 (not shown), which is connected by lever 91, Fig. 1, pivoted at 92, to rotate cam member 79 in the opposite direction. Cam member 79 is spring-loaded, Fig. 8 (not shown), to oppose the piston motors of cam member 78. The pump has two inlets 24 opening into its casing 20, Fig. 2 into which valve member inlet ports 68, 69 also open. Outlet ports 45, 46 are connected to a common outlet 26, port 46 communicating with outlet 26 via pipes 49, 50. Passages 72 through the valve member, together with check valves 73, 74 connecting respective passages 72 to adjacent outlet ports, equalize the pressures in the cylinders traversing the valve member bands. The valve member is supported by couplings 40, 41 for limited angular and axial movement for aligning with the cylinder blocks, which are urged towards the valve member by output pressure applied to annular chambers 60 between the blocks and drive flanges. Drive is transmitted between the drive flanges and blocks by engagement of block lugs 58 in flange recesses 59, springs 58a urging the blocks against the valve member.

Title: Process and apparatus for producing litharge
IPC: C01G21/06
Filed: 1963-12-24
Abstract: <PICT:1069430/C1/1> Litharge is produced by feeding molten lead into an oxide pot of the Barton type in a continuous stream at a rate which maintains the contents of the pot at a temperature of at least 621 DEG  F. (the melting point of metallic lead) but below 900 DEG F., vigorously agitating the pot contents by means of a stirrer which throws the pot contents against a large fixed baffle, introducing a stream of air into the pot, and maintaining the pot free from any pool of molten metallic lead, the resulting product being carried away from the pot via a cyclone separation system where the heavier products are separated and returned to the pot as a dross which is maintained in the pot at all times. The stream of air is introduced into the lower portion of the pot, i.e. just above the stirrer where the majority of the dross is located. The litharge product is of fine particle size, for example 5 microns, having a high acid absorption value (between 160 and 180 as defined in the Specification), low apparent density (20 to 25 grams per cubic inch), and low content of metallic lead (below 4%, preferably below 2%, by weight).  The litharge may be produced in apparatus, see Fig. 1, comprising a Barton pot 10 which is similar to that pot disclosed in Specification 501,175, but which is modified by having the air inlet pipe 16 extending into the lower portion of the pot.  The apparatus is generally similar to that disclosed in Specification 966,925, but is modified by having the elongated uptake 17 communicating and co-operating with a cyclone separator 18, desirable size particles being passed via duct 17a to the settling chamber 19, larger and heavier particles being passed from the lower end of the cyclone separator by rotary feeder 41 either via screw conveyer 42, return tube 43 and the air inlet pipe to the pot or via rotary feeder 44 and screw conveyer 45 to the settling chamber.
