摘要： A first pipe of metallic material has a cup-shaped socket at one end, and a second pipe of metallic material has a flange at one end which is received with clearance in the socket of the first pipe. The bottom wall of the socket is juxtaposed with the axial end face of the flange. The latter is provided in this axial end face with an annular groove concentric with the pipe and having an inner diameter equal to the inner diameter of the pipe and an outer diameter smaller than the outer diameter of the flange. An annular member of rigid electrically insulating material is fixedly received in this groove, having an inner diameter at least substantially equal to the inner diameter of the first groove. A second annular groove is provided in the bottom face of the socket and has an outer diameter at least equal to the outer diameter of the flange and an inner diameter larger than the inner diameter of the first groove but smaller than the outer diameter of the same. A second annular member of elastically yieldable electrically insulating material is received in the second groove and has an inner circumferential margin in fluidetightly sealing engagement with the corresponding outer circumferential margin of the first annular member. Discrete first and second coatings of electrically insulating material are respectively provided on the inner surfaces of the respective tubular members and each extended to the juncture between the tubular members. Means is provided filling the clearance and connecting all of the members mechanically against movement and in electrically insulating relationship.

摘要： A metallic element which is to be cathodically protected against corrosion has secured to one of its surfaces a strip-shaped anode extending along at least one generatrix and being in substantially continuous electrically conductive contact with such surface so that current will flow between the strip, which constitutes an anode, and the element, which constitutes a cathode, at substantially identical density all along the strip.

摘要： A first pipe has a barrel-shaped female end portion and a second pipe has a similarly shaped male end portion received in the female end portion so that they define between themselves a substantially barrel-shaped clearance. Received in stressed condition at one end of the clearance is an annular sealing gasket and received in similarly stressed and compressed condition at the other end of the clearance, adjacent the open end, is an annular locking ring of hard rubber or the like, a portion of which is received in an annular groove provided in the inner circumferential surface of the female end portion or in the outer circumferential surface of the male end portion. The space between the sealing gasket and the locking ring is filled with a hardened flowable material which has been introduced through a hole provided in the female end portion and communicating with the clearance.

摘要： A method for connecting pipe sections having a corrosionresistant lining in which a pair of sockets are connected at small diameter ends substantially equal to the outer diameter of the pipe sections to the latter, spaced from facing ends of the pipe sections with the remainder thereof, a larger diameter portion of each socket, projecting beyond the end of the respective pipe section, in which a sleeve of a material resistant to heat and to the corrosive influence of the liquid to be conveyed is placed between adjacent ends of two pipe sections, and in which the other ends of the sockets are connected to each other by at least one weld seam which is thus radially spaced from the pipe sections and the lining thereon so that the lining is not damaged by heat during forming of the weld seam. After forming of the weld seam the space between the sockets and the pipe portions enclosed thereby is filled with a molten hardenable compound having a melting point lower than that of the pipe lining, and which, however, can not damage said lining.

摘要： 1,209,164. Liquefied gas-storage containers. L. BAGNULO. 7Nov., 1967 [1 Nov., 1966], No. 49637/67. Heading F4P. [Also in Division F2] Means for discharging a predetermined volume of gas from the gas space of a liquefied gas, e.g. petroleum gas storage cylinder 3, Fig. 1, when a two-position discharge valve 21 is opened by moving an external lever 13 from its closed to open position shown in Fig. 3 comprises a float 40 which when the lever 13 is in the open position is latched to a rod 26 extending through the float and having its upper square end 25, Fig. 4, in sliding engagement with a squaresectioned chamber 24 formed in the lower end of the valve 21 and carrying an abutment 36 which when the float 40 sinks a certain distance, irrespective of the liquid level, releases a valveholding pin 30 thereby allowing the valve 21 to be closed by a spring 19 even though the lever 13 remains in the open position. The lever 13 is fixed to an arbor 12 which projects through a fixed member 14 and has a square end 16 slidable in a recess in the upwardly spring-biased head 17 of a shank 20 integral with valve 21. The upper end of the head 17 has diametrically opposed cam lugs 18, 18 1 , Fig. 5, which when the lever, arbor and head are rotated ride over lugs 15, 15 1 on fixed member 14 resulting in opening of valve 21 to a position in which a notch 37 is engaged by the pin 30. The rotational movement of the valve when being opened is transmitted to the rod 26, which after a 90 degrees turn is latched to the float by engagement of diametrical longitudinal extending ribs thereon with spring clips on the float and the rod is thus moved downwardly by the float as the liquefied gas vaporizes until the abutment 36 strikes a lever 33 to withdraw the pin 30 and allow valve 21 to be closed by its spring 19. To effect a further discharge of gas lever 13 is moved from its open to its closed position resulting in rod 26 being rotated 90 degrees and unlatched from the float 40 and returned by its spring 49 so that its square end 25 is near the upper end of chamber 24 in valve 21 and the lever 13 is then turned to the valveopen position. In a modification the upper square end of the rod 26, Fig. 8, is in direct sliding engagement with the arbor 53, and the two-position valve 55 is unseated by an arm 56a of a three-armed lever 56 having an arm 56c engaging a cam slot 51 in an extension 52 of the arbor 53. The third arm 56b when engaged by the abutment 36 on rod 26 in its lower position rotates lever 56 to close the valve 55. As in the previous embodiment rod 26 becomes latched to the float when the manual lever 54 is turned from the valve-closed to valve-open position and the rod remains latched until the lever is returned to the valve-closed position.
