A communication system capable of continuously exchanging digital information in a well logging installation between apparatus arranged on the earth's surface and apparatus arranged in an earth borehole, interconnected by a cable. Both the surface apparatus and the downhole apparatus include a controller and a modem for sending digital command messages downhole and digital data messages uphole. Th...

PURPOSE:To perform abrupt travel/stop operation without changing step of pedal even under deflock operation by interlocking a differential device with the pedal. CONSTITUTION:A cam 28 for pressure operating a shift fork 26 through stepping under initial non-travel/stop operation range (a) and following travel/stop operation range (b) to the deflock side is fitted over a rotary support 12A rotatabl...

The major surfaces of a solid plate-like conductive core in an accumulator are adjacent to slabs of positive active material which are flanked by porous layers consisting of sintered synthetic plastic material or of compacted glass wool, synthetic plastic filaments or rock wool. A sheath consisting of polyvinyl chloride has a chamber which receives the core, the slabs and layers and is formed wit...

The subject of the inventon is a safety lock for granulators whose housing is divided in a plane running through the axle of their granulator rotor into an upper part and a lower part, the upper part being connected to the lower part so as to swivel about an axis parallel to the axle of the granulator rotor and the granulator rotor being mounted in the upper part. This safety lock consists in the ...

PURPOSE:To enable an operation of the device in a fully high efficiency, further in a high response manner when necessary, by effectively switching operating conditions in a high efficiency and high response which are oppositely characterized to each other. CONSTITUTION:In the combined-cycle generating plant which is provided with a plurality of gas turbine driven generators and at least a steam t...

PURPOSE:To prevent the ends of strands from projecting unevenly to produce a knot-like small projection by forming portions of each yarn end to be untwisted and enveloped in a continuous groove and applying to the yarn end a jet air stream directing to the opening of the groove in the groove. CONSTITUTION:The yarn end YP on the package side is fitted in a groove 57 by turning a swivel guide plate ...

PURPOSE:To shorten the time of ending and eliminate the need of a yarn cutter by untwisting a yarn end in a yarn end untwisting groove and at the same time bringing strands of the yarn into contact with a projection mounted on the inner wall of the groove by an air stream for untwisting, thereby to cut the yarn end. CONSTITUTION:Filament collecting levers 27, 28 are turned to insert the yarn end Y...

PURPOSE:To improve the battery life by initially charging an unformated plate fabricating lead-acid battery, when a current is flowed at low temperature initially and the temperature is increased gradually. CONSTITUTION:When an unformated plate fabricating lead-acid battery is initially charged, a current is flowed keeping the battery temperature at a low temperature suitable for the negative elec...

In the case of a control system or regulating system for a paste feed shaft, the density and the thickness of a lead-oxide paste, which is applied onto a strip of a battery grid material via a feed shaft, are controlled or regulated independently of one another as a function of in-line measurements of the density and thickness downstream of the paste feed shaft. The paste density is controlled or ...

A tire manufacturing mold comprising a profile ring having a contour corresponding to the outer profile of a tire being molded, including at least the tread thereof, and a net ring having a faying surface for making contact with the contour surface and consisting of ribs and/or lugs for forming the grooves of the tire being molded. The net ring is disposed on the contour surface of the profile rin...

A high pressure apparatus in which a support frame which undergoes axial tension includes a divided body composed of first and second support frames, the first and second support frames being brought into engagement with each other at an outward area in a diametrical direction of upper and lower covers and being freely changed in position between the engaging position and a position separated from...
