Abstract

1,270,122. Gear pumps and motors. PLESSEY CO. Ltd. March 4, 1970 [March 6, 1969], No.11998/69. Heading F1F. [Also in Division C7] A gear pump (or motor) wherein at least the teeth of the gears are made from a material consisting of a dispersion of hard metal carbides, silicides, borides or nitrides in a heat-treatable ferrous matrix. A suitable material is that known as Ferro-TiC-grade C. This material may be machined prior to heat-treatment to its ultimate shape with the addition of a very small finishing allowance which may be removed by grinding.
