Title: Rheological drilling fluid props - measured in actual well by apparatus with temp pressure and pressure differential meters
IPC: E21B49/00
Filed: 1973-11-23
Abstract: The rheological properties of drilling fluids are measured by fitting the appts. at the end of the drill string, with the drilling fluid passing down in the bore of the drill string and up in the annulus between drill string and well walls. The appts. has a smaller passage area than the drill string and the pressure loss caused thereby is measured continuously. This provides truer results because the conditions are not those simulated in a pure laboratory test but field conditions. The tests can be arranged to ensure a laminar flow for the drilling fluids.

Patent FR-2288168-A1 (FR)
Inventor: GREENWAY J M
IPC: D02G1/02
Filed: 1975-10-17
Abstract: The device comprises a means for forming at least one fluid vortex in the form of at least one chamber (11) of round cross-section which has channels (12), entering at right angles to the longitudinal axis and tangentially in the outer wall of the latter, for the introduction of a fluid and cylindrical tubes (13, 14) for the introduction and removal of the yarn (15), which are arranged coaxially at both ends of the chamber, in order to ensure that, when the device is in operation, the run-through path for the yarn extends virtually along or parallel to the longitudinal axis of the fluid vortex formed in the chamber and extending into the two tubes. The device makes it possible to transfer heat both from the fluid to a yarn and from the yarn to the fluid and results in virtually no yarn twisting or looping of the individual filaments of a multifilament yarn running through. It is thus suitable for the thermosetting of multifilament yarn crimped by false twisting.

Title: Electrostatic pptn. installation - in which voltage drop on electrode gaps falls to zero on change of supply voltage
IPC: B03C3/66
Filed: 1975-11-03
Abstract: Installation for electrostatic precipitation comprises two electrode gaps, each formed by receiving and corona electrodes and a high-voltage rectifying unit embodied on the basis of a transformer. The high voltage winding of the transformer is provided with a gate circuit having two opposing gates and connected in parallel to the high voltage winding, the common point of the gates being electrically connected with the receiving electrodes. The high voltage winding of the transformer is also connected via linear electric elements to the corona electrodes to provide for the formation of a discharge circuit for each of the electrode gaps alternately via the high voltage winding of the transformer and the other electrode gap. The voltage drop on the electrode gaps falls to zero at each period of change of supply voltage, resulting in discharge of the layer of high-resistance dust settled on the electrodes, elimination of "inverse corona", and an increase in the efficiency of high resistance dust pptn.
