A process for recovering at least 70% of hollow glass microspheres having an average diameter according to ASTM D1214-1989, ranging from 5 to 200 gm, contained in a mixture of mud and drill cuttings comprising: sieving, if necessary, the mixture through one or more 5 to 20 mesh sieves; ...
aA process for polymerizing ethylene which comprises contacting ethylene at a temperature of from about ambient to about 70C with a polymerization initiator comprising a complex of an alkyllithium compound with 1,2-dipyrrolidinoethane and recovering the polymerization product. 一个过程为聚合包括与乙烯...
It is then finally released either on command from the boat 5, as is advantageous, or else by means of a mechanical device placed on the reception means 18 and triggered automatically at the end of the stroke of said reception means.
At this time the tilt angle of the motor 16 is controlled in accordance with the stroke of the brake pedal 53. Pressure oil generated from the motor 16 is charged in an accumulator 41 through a hydraulic passage 40. Upon starting, when an accelerator pedal 51 is depressed, a valve 81 ...
This impasse was overcome in [17] where, starting from [22], a new formulation of the dimensionless model was presented and studied, more in keeping with the industrial reality of the MEMS devices produced, which also considers the effects due at the fringing field. This dimensionless model ...
In the present study, the waste heat source is reject from a low-speed two-stroke marine diesel engine. The waste heat source parameters are presented in Table 1. The exhaust gas’s composition is shown in Table 2. The composition parameters are applied for calculating the dew point and the...
