| No. Patentee Title 526,260 J.P. Johnson Gear Pumps The pump body is made of light weight material, a stiff soft rigid inset therein defines the operating chamber and has formed integrally with itself bearings for the gears. 526,261 Ditto Fluid pressure seals. The pump shaft is capable of limited axial movement with reference to its bearing surface and with respect to the pumping element which it drives, means rigid with the shaft define an axial thrust bearing surface, a rigid sealing ring cooperates with this bearing surface, resilient means between the ring and its supports urge the drive shaft to press the said surface on to the said ring, the resilient members taking up any tilting movement necessary for proper alignment. 526,871 F.{Mr Friese} Schichau Ges. Internal combustion engines using solid pulverulent fuel. Means for the disposal by air or gas of sludge formed in engines of this type. 526,310 G.{Mr Griffiths - Chief Accountant / Mr Gnapp} H.{Arthur M. Hanbury - Head Complaints} Taylor Air cooled internal combustion engines. The engine employs a 6 stroke cycle, air for cooling being sucked in and exhausted between the normal exhaust stroke and normal inlet stroke. ----------- | ||
