Title: Time dependent trace display and trace recognition system - permits evaluation of spot speed on trajectory for recognition of objects by radar signals
IPC: G01R13/22
Filed: 1975-05-15
Abstract: The system is for graphical forms, and has a transducer and a receiver display. The system has also means for simultaneously combing data from one or several transducers (1) into a predetermined number of voltage signals. These voltage signals a respectively proportional to as many weighted data summations. The system has means for respectively controlling the displacement of the spot of the display receiver in the direction of abcissae and in that of ordinates. This displacement is achieved by voltage signals selected from amongst the weighted data addition signals. There are also means for sampling data addressed by the transducers to data combiners. The signals displayed on the viewing receiver consisting of a matrix of points.

Title: Hydraulic concn. of mineral phosphate slurries - by addn. of a soln. of flocculating agent before filtration of the enriched slurry
Inventor: CHEHATA MOHAMMED
IPC: B03B7/00
Filed: 1975-06-10
Abstract: Treatment of phosphate minerals comprises washing and flaking the crude mineral, removing fines and concentrating the slurry, then adding a flocculating agent before filtration to agglomerate the remaining fines in the slurry, which is then filtered and the solid dried conventionally. The filtrate is recovered and recycled after purification. Fines are more completely removed leading to more rapid sepn. of the solid from the liquid phase, and a drier cake issuing from the separators. The liquid phase is more readily purified for recycling. Typically, the moisture content of the sepd. mineral phosphate cake before drying was reduced from 15-16% to about 10-12% by contact for 15-60 secs. with a flocculating agent.
