Abstract: Abstract A method for separating solid phase from drilling mud, comprising forming from drilling mud an adhesive layer on a resolving closed curvilinear surface by partially submerging it in the drilling mud and forming from a treatment liquid an adhesive layer on another closed cur-vilinear surface which is caused to rotate in the direc-tion opposite to the rotation direction of the first curvilnear surface.  Both closed curvilnear surfaces are arranged in such a manner that their adhesive layers prenetrate one another at a depth sufficient for the adhe-sive layer of the treatment liquid to take-off coarse solid phase particles from the adhesive layer of the drilling mud.  Linear velocities of the adhesive layers are chosen in such a manner that the resultant centrifugal forces be equal to or lower than the centrifugal forces.

Abstract: ABSTRACT OF THE DISCLOSURE   A method of manufacturing a molded wheel and brake assembly. The molded wheel has a hub awith an axial bore therein with a first diameter and a smaller second diameter.  The surface of the second diameter is finished in order to establish concentricity between that portion of the axial bore and the peripheral surface of the wheel. A cylindrical member is machined to establish a guide section separated from a knurled section by a relieved section on the peripheral surface thereof between a first end and a second end.  The first end is positioned in the first diameter of the axial bore and a force applied to move the cylindrical member in the axial bore.  The guide surface engages the second diameter to align the knurled section in the axial bore.  On further movement of the cylindrical member, the knurled section broaches the hub to thereafter prevent rotative movement between a brake assembly located in the cylindrical member and the hub.

Abstract: Abstract A telephony network with a digital central office and one or more remotely located digital satellite units.  Each digital satellite unit connects to a number of remote subscriber lines and monitors these lines to establish communications through interconnecting spans and a digital satellite interface at the digital central office.  The digital satellite interface also connects to port group highways in the digital central switch, to call processors in the digital central switch, and to a maintenance processor in the digital central switch.  An automatic test circuit communicates with the interface, and each remote digital satellite unit contains complementary testing circuitry.  A test call is made to test the system by activating a test access relay at the remote digital satellite unit and producing a call to the automatic test circuit.  The automatic test circuit then generates a tone that is carried as voice data to the remote digital satellite unit test circuit.  If this tone is received, the test circuit at the digital satellite unit sends a tone followed by dial pulses.  If the automatic test circuit receives the tone and dial pulses within specifications, the automatic testing has passed and no further action occurs.  If it fails, a message is sent back to the digital satellite interface, so various levels of diagnostics utilizing the automatic test call circuit can be performed to isolate the cause of the failure.

Abstract: SEMICONTINUOUS CASTING PROCESS   ABSTRACT    A semicontinuous casting process comprises stepwise uphill feeding of molten metal into the mould cavity up to a dummy bar, holding the metal in the mould until a skin of casting is formed to a preset thickness, withdrawing the casting for a given length and concurrently feeding molten metal into the mould cavity in an amount corresponding in volume to the given length of withdrawal, wherein after ini-tial feeding of metal into the mould and after that follow-ing each successive step of the casting withdrawal from the mould, the feeding of the molten metal is continued and the latter is then removed beyond the boundary of the dummy bar in volume equalling 0.1 to 0.9 time that of the mould ca-vity. During the holding time,  a part of the molten metal is returned, at least for once, into the casting being formed and then is again removed beyond the boundary of the dummy bar. Before the casting formation process is complet-ed, a major part of the molten metal volume is introduced into the casting being formed, whereupon the feeding of molten metal is discontinued until complete solidification of the casting.      The invention is readily adaptable to a semicontinuous casting practice for the production of castings which are drawn up from a mould.
