IPC: E21B/
Filed: 1986-03-03
Abstract: A choke valve especially used for regulating the flow volume and with it the back pressure of liquids or gas while drilling through shallow gas bearing formations from an off-shore drilJing platform comprises a flexible cylindrical valve element (8) positioned in the flow passage of the valve housing (1), the valve being designed such that the valve element's (8) flow area can be reduced by a radial reduction of the valve element. The flow area of the valve element (8) is equal to or larger than the remaining flow area of the valve. The valve has devices (10) for constricting the end of the valve element (8) being nearest to the outlet opening (3) of the valve. The valve element (8) is long enough that it is possible to compensate for the wear, to which the end is exposed, by sliding the valve element against the constricting devices (10) or by moving the latter along the valve element as wear proceeds. Only the valve element (8) is exposed to wear and no other parts of the valve are positioned within the wearing zone. The valve element (8), in its withdrawn position, has its total diameter free allowing a full flow through the valve. Accordingly, the valve does not disturb the flow under normal conditions and is not exposed to any wear. At a gas kick the well can be controlled during a long period as it is possible to compensate the wear on the valve element during operation.

Abstract: 859,069. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan. 5, 1959 [Jan. 20, 1958], No. 383/59. Class 39(4). The flow of coolant in the fuel channels of a nuclear reactor is regulated by the insertion of an orifice of the required size in the channel. The orifice may be inserted or removed without disturbance of the fuel elements and is placed at the lower end of the channel. As shown, the orifice 15 is hollow and permits the flow of coolant through 13, 14 in the channel 7a. It is retained in the channel by the retractable fingers 18 which engage the recesses 17. The weight of the fuel elements in the upper part of the channel is supported by the retainer 6. To remove 15, it is first moved upwards until the fingers 18 are urged inwards by the walls 7b. During the subsequent movement downwards, the sleeve 27 tends to be held by the springs 19 which engage the channel walls 7a. The fingers 18 therefore are engaged and locked in the inner position by the upper rim of 27 and 15 may be removed from the channel. During the upward insertion of 15, the sleeve 27 tends to be dragged back by the friction action of the springs 19 and the fingers 18 are released to engage 17.

Abstract: 1,160,878. Current collectors. ADDRESSOGRAPH-MULTIGRAPH CORP., CHARLES BRUNING DIVISION. 4 Jan., 1967 [20 Jan., 1966], No. 574/67. Heading H2E. [Also in Division G2] In a contact-printing apparatus, the superposed sheets are fed in over a table 26a, and carried by a belt system 36 so as to pass round the printing lamp 50, which itself rotates, directly in contact with the lamp envelope itself. The sheets leave the apparatus through a discharge opening 24. Fig. 3 shows the arrangement for conveying current to the rotating lamp. An end cap 70 is electrically connected to one terminal 66 of the electrode 63, but insulated from the other terminal 67. A connector 74 is insulated from the terminal 66 and cap 70, but connected to terminal 67. Fitting centrally into connector 74 is a contact button 86, with which a leaf-spring member 90 makes contact. Member 90 is connected to a terminal bracket 98 connected in turn by a conductor 101 to a power supply. An identical arrangement is provided at the other end of the lamp with regard to terminals 64, 65 of electrode 62. Thus a potential can be continuously applied across the lamp as it rotates. Starting.-To assist in starting the lamp discharge, a bar 104 is rotated by a handle 108 so that contactors 110, 112 are brought into contact with end caps 68, 70, respectively (position of Fig. 3), thus reducing the resistance gap between electrodes 62, 63. Current then flows from contactor 88 to contactor 90 via electrode 62, bar 104, and electrode 63, for a short period, after which the bar is returned to its non- operative position. Although the lamp may be started while rotating, it is preferred that it should be stationary, and a switch is mounted on handle 108 such that when the handle moves rod 104 into the "starting" position, the drive circuit to the lamp is broken (Fig. 4, not shown). A pair of auxiliary contacts (114a, 114b, Fig. 4) is provided so that the starting circuit is not completed until after contactor 112 engages end cap 70, so that no arcing between contactor and end cap occurs.
