Abstract: Den foreliggende oppfinnelse vedrører en fremgangsmåte for overvåking av lekkasjer i underjordiske kunststoff rør, særlig i kunststoffrør lagt gravefritt i jordbunnen, hvilke oppviser i det minste ett indre lag av kunststoff likesom i det minste ett ytre lag av kunststoff, hvor i det minste to omtrent vindelformede elektriske ledere som strekker seg om røraksen, er lagt slik i kunststoff rørets vegg at de ikke kommer i berøring med hverandre, og hvor det anvendes en innretning, ved hjelp av hvilken det måles og/eller indikeres om det foregår strømflyt gjennom en av lederne. Ifølge oppfinnelsen blir det på en første elektrisk leder (4) påført en permanent likespenning, en andre leder (5) som er ført vindelformet omtrent parallelt med den første leder, jordes, og en strømflyt som oppstår mellom de to ledere (4, 5) ved uttrengning av medium som strømmer i kunststoffrørledningen, og/eller på grunn av jordfuktigheten ved beskadigelse av rørledningens ytre lag, blir målt og/eller indikert.

Abstract: A well pump assembly has a motor operatively connected to a well pump that has an intake. The well pump assembly has a capillary tube that extends alongside the tubing and has an outlet at the well pump assembly. A Chemical injection pump is connected to an upper end of the capillary tube adjacent a wellhead of the well. A logic system detectswell fluid falling backdownward in the tubing and out the intake into the well, and in response turns on the chemical injection pump, which pumps a chemical down the capillary tube into the well adjacent or within the well pump assembly. Once upward flow of well fluid in the tubing has been established, the chemical injection pump may be turned off.

Title: Method of cooling continuously cast ingots and apparatus therefor
Inventor: BOBADILLA MANUEL
IPC: B22D11/124
Filed: 1989-05-12
Abstract: The method according to the invention is characterised in that an intense cooling of the product in the process of being continuously cast is carried out when the latter is, at its core, in the pasty solidification phase (8), as a result of which the differential thermal contraction between the pasty core and the outer shell which is already completely solidified produces a squeezing effect of the core by the shell (9). To this end, means for cooling the product are arranged on the casting machine in the region of the terminal portion of the metallurgical length. 
<??>The invention makes it possible to reduce, and even prevent the formation of internal cracks during the cooling of the cast product, which would lead to the presence of segregated areas in the axial region. It is applied advantageously to the casting of steels which are well known to be difficult to cast by continuous casting, such as steels with a wide solidification range, the carbon content of which is from 0.25 to 1.5%.

Abstract: In an insert valve that can be mounted in an insert connector (3) of a fluid line (1)and that has a cylindrical presetting element (15), which is rotatable relative to a valve housing (5) via an adjustment ring (14) and a transmission element (12), and unrotatable relative to the transmission element (12), and that guides a valve rod (22) carrying the valve closing piece (28) to be displaced to a limited extent coaxially, relative to the valve seat, the presetting usually has an axially projecting wall part, which, in dependence of the rotary angle position of the presetting element leaves openings (34) open or covers them partially or completely. With complete covering, however, a leakage may occur, which is not desired. According to the invention, however, a rotation of the adjustment element (14) in relation to the valve seat (43) and the transmission element (12) displaces the presetting element (15) in the one direction axially until a first stop (31; 21) and in the other direction until the valve closing piece (28) bears on the valve seat (43). Thus, here the valve closing piece (28) provides a complete blocking of the flow when the kv-value is set at 0. <IMAGE>
