Title: Tubing anchor for well apparatus
IPC: E21B23/01
Filed: 1957-09-17
Abstract: 868,647. Anchors for wells. BAKER OIL TOOLS Inc. Sept. 17, 1957 [Jan. 22, 1957], No. 29279/57. Class 85. An anchor for fixing a well string A within a well conduit B comprises a member 10 connectible with the string, an expander 22 mounted to slide along the member, slips 18 carried by the member and moved by the expander into anchoring engagement with the conduit, and drag means connected with the expander and adapted to frictionally engage the conduit. The slips are carried by a ring 29 mounted on the member to have a limited movement between a spring 33 and a shoulder 32, tongues 27 on the slips engaging grooves in the ring. Further tongues on the lower ends of the slips engage grooves in the expander which is integral with the drag means. The drag means has parts 41a urged outwardly by springs 48. The anchor with its slips retracted is fixed to the lower end of the string A which is lowered down the well to the required extent. The string and member are rotated anti-clockwise, threads 39 on the member coacting with threads 38 on the drag means so that the expander moves upwardly relative to the member and forces the slips outwardly since rotation of the expander is prevented by the drag means. After the slips have engaged the casing B the spring 33 is compressed. After the string is anchored to the casing the string is tensioned and fixed at the surface. Should the length of the string change due to temperature variations, or as a result of the action of a well pump, the slips and expander move bodily down along the casing as the string lengthens but any contraction of the string is resisted by the expander wedging the slips more tightly against the casing. The initial tensioning of the string may be dispensed with since the anchor will automatically tension the string as it changes length. The string is freed from the casing by clockwise rotation of the string and member to retract the slips. A flange 56 provided on a shield 54 may be fractured by dirt pressure during the clockwise rotation so that dirt which has entered the anchor does not prevent the retraction of the slips. In a modification (Figs. 7 - 10, not shown) the thread 38 of the drag means is formed on a nut having a shear connection with the drag means so that if the member will not rotate relative to the expander and drags means the slips may still be retracted by lifting the string to shear the connection and to permit the shoulder 32 to lift the ring 29.

IPC: H04L1/24
Filed: 1969-06-10
Abstract: 1,261,749. Digital transmission systems. HEWLETT PACKARD Ltd: 10 June,. 1969, No. 29447/69. Heading H4P. A test signal of known pattern is generated and applied to a channel the output from which is compared with a similar signal generated at the receiving end. The test signals are derived from shift. register generators which may generate pseudo-random signals or predetermined words which recirculate indefinitely. A feed forward shift register differentiates between synchroniza tion loss and error bursts. A test sequence is produced in synchronism. with a clock 17 by using a shift register 19 connectible as a pseudo-random or predetermined word generator. The receiver has a similar generator 21 with the facility that a signal on line 23 causes generator 21 to synchronize onto the received data. Generator 21 may be triggered by a clock extraction circuit 22 if a local clock is not available. Generator 21 output is compared at 25 with the received sequence and fed to a display 27. The comparator 25; output is also fed to, a. shift register in a synchronization loss detector 29 which distinguishes between loss of synchronism, which gives a signal on line 23, and errors. A violation detector 31 detects whether a sequence is being properly generated. Gating circuits (not shown) may be included to prevent a display of error information if there is a loss of synchronism. The shift register generators may comprise a series of programmable flip-flops (33-41) connected to receive, on one input; clock pulses and on another input either the output of the preceding flip-flop or the mod 2 sum of the precoding flip-flop plus the output of the last flip-flop (41) (see Fig. 3, not shown). Alternatively a similar feedback register (48), see Fig. 5 (not shown), may be coupled to a feed forward register (50) so that after six clock pulses the contents of the registers will be identical. In Fig. 7. (not shown) a local generator 53 isswitohable to a feed forward or feed back mode: In position (2) of switch (55) the shift registers in transmitter and receiver act identically to produce a desired error information at the output of a non-equivalence gate (57). With switch (55) in position (1) synchronization will takeplace. In Fig. 8 (not shown) a shift register (59) is connected to recognize the sequence of errors caused by loss of synchronization.
