Title: Electropolishing interiors of cylindrical vessels with domed ends - - and their assembly by welding
Inventor: JUMER JOHN F
IPC: C25D7/04
Filed: 1972-06-20
Abstract: Cylindrical vessel and the domed ends are first polished and then assembled by welding. The welds are ground smooth by welding and the inner surface of the vessel is polished using a pendant cathode immersed in a shallow bath of electropolishing solution whilst the vessel is slowly rotated about a horizontal axis. The cathode assembly is then removed and the electropolishing solution emptied out. Protruding access nozzles in the domed ends are elect polished separately.

Title: Dewatering of fine moist solids by atomisation - at high velocity to ensure sepn of moisture droplets as aerosol in air stream
Inventor: SOKOLOW MICHAIL A
IPC: B01D1/18
Filed: 1972-10-27
Abstract: Moisture is removed from dispersed solids by high velocity atomisation into an ambient temp. airstream. At spray velocities >100 m/s the free moisture forms droplets of dia 30 mu m which form an aerosol in the air stream while the solid particles fall to the bottom. This essentially mechanical sepn. requires 40 kcal to remove 1 kg H2O compared with a min. of 600 kcal by thermal means.

Title: Hermetically encapsulated resistor - with cylinder coated in resistance material, has metal end caps holding coated cylinder encapsulated in glass tubes
Inventor: HENTSCHKE PETER DIPL PHYS
IPC: H01C1/146
Filed: 1973-06-18
Abstract: The resistor has the ends of the cylinder coated with resistive material fitting inside circular, pressed-out recesses in the metal end caps.

Title: Electrochemical machining metal - using non-conductive inert nozzles and cathodically charged electrolyte
Inventor: ANDREWS JAMES DAIR
IPC: B23H9/16
Filed: 1973-12-14
Abstract: Holes are drilled in a metal workpiece electrochemically by impinging a jet of cathodically charged electrolyte against a starting surface of the workpiece which is anodically charged. A low potential is maintained until a dimple is formed in the workpiece which will direct the electrolyte away from the workpiece. The potential is increased as cavitation increases and maintained to cause drilling at the point of jet impingement until the hole is formed. The potential is again increased for a period to develop the hole to a desired diameter. Pref, the potential is increased in increments and the nozzle forming the electrolyte jet is positioned below the workpiece at a distance to facilitate electrolyte drainage. A plurality of nozzles are utilised for providing multiple cavities simultaneously.
