Wearing element with enhanced wear resistance related to wearing elements, such as cast steel teeth to be specially used in machinery for earth-moving, ground-engaging and/or rock-loading applications, as well as to inserts to be included within the wearing elements, to enhance their wear resistance thus prolonging their service life.
摘要:
The present invention is generally directed to an apparatus for harvesting algae using a two-stage approach. The two-stage approach includes a flocculation stage and a dewatering stage. The flocculation stage is implemented within a first-stage flocculation tank in which algae suspended within a growth medium is flocculated. The flocculated algae is then fed to a second-stage flotation tank in which electrodes are used to produce hydrogen and oxygen bubbles which attach to the flocculated algae causing the flocculated algae to float to the surface. The mat of floating algae can then be skimmed off the surface of the growth medium.

摘要:
An integrated sensor assembly (10) includes a gas compression unit (104) having a first longitudinal axis (308) and a gas expansion unit (112) having a second longitudinal axis (366) and the gas expansion unit is disposed with its second longitudinal axis orthogonal to the gas compression unit first longitudinal axis (308). A rotary motor (302) includes a rotor (324) supported for rotation with respect to a motor rotation axis (328) and the sensor assembly configuration is folded to orient the motor rotation axis substantially parallel with the second longitudinal axis (366). A motor shaft (320) extending from the rotor includes a first and second mounting features (336, 340) disposed substantially parallel with and radially offset from the motor rotation axis (328). A first drive coupling couples between the first mounting feature (336) and a gas compression piston (304) and drives the piston (304) with a reciprocal linear translation directed along the first longitudinal axis (308). A second drive coupling couples between the second mounting feature (340) and a gas displacing piston (362) and drives the piston (362) with a reciprocal linear translation directed along said second longitudinal axis (366).
