Title: Improvements in ball-winding machines comprising an automatic ball draw-off and ejector apparatus
IPC: B65H54/66
Filed: 1964-09-17
Abstract: The invention is an improvement on the ball winding machine of Specification 1,060,881 and includes means whereby.  (a) At the end of a ball winding operation the main motor, driving the winding blades and spindles and for effecting reciprocating swivel movements of a spindle beam carrying said winding spindles, is switched to slow running for a pre-determined period and then stopped;  (b) Upon initiation of slow running of the main motor the motor used to adjust the diameter of the winding cores is operated to reduce the diameter of said cores and a further motor is operated to actuate the yarn cutting and clamping means;  (c) Upon stopping of said two latter motors, the motor operating the ball draw-off and ejector apparatus is operated and then stopped; and  (d) After the ball draw-off and ejector apparatus has been operated the associated driving motor is stopped and the motor controlling the diameter of the winding cores is again operated to expand said cores.  Thereafter the motor used to control the thread clamping means is again operated to release said clamping means.  On the switching off of the main drive motor after the completion of a winding operation, a separate drive motor for the conveyor belt is operated.  Each gripper device, Fig. 2 (not shown), consists of angle levers (122) which are mounted on a gripper support (120) so as to be rockable towards a central axis, have needle-shaped pins (123) on one long arm, which when said angle levers are in an inoperative position are covered by said gripper supports (120) and wherein, by means of axial movements of a bolt (33) in one direction along said central axis, to which bolt (33) said angle levers (122) are connected through a spring (125) each angle lever (122) is swung into an operative gripping position in the direction of said central axis and by movement of the bolt (33) in the opposite direction is moved back into the inoperative position by means of a pin (127) which is mounted on said bolt (33) and which acts on the other lever arm (122a) of said angle lever (122).

Title: Safety means for well flow control
IPC: E21B34/08
Filed: 1973-08-10
Abstract: 1445602 Controlling flow in wells SCHLUMBERGER TECHNOLOGY CORP 10 Aug 1973 38095/73 Heading E1F A system for terminating flow through a well conduit 10 comprises a first sub-surface valve 20 which closes in response to pressures in the conduit below a first level, and a second sub-surface valve 50 which closes in response to pressures in the conduit above a second level higher than the first level. The valve 20 is preferably above the valve 50 so that closing of one valve will cause the pressure to change so as to close the other valve. The valves may be closed, for example to test them, by closing surface valve 12, so that the pressure rises and valve 50 closes; then surface valve 12 is opened so that the pressure falls and valve 20 closes. The valves are locked when opened by respective locking balls 42, 95 held in place by shafts 34, 92 connected to bellows 40, 112 communicating with reservoirs 41, 120 containing compressible fluid. If the pressure falls below the first level, bellows 40 will have expanded far enough to release the locking balls 42-so that spring 42a urges valve member 33 onto seat 32; the valve is reopened by imposing from the surface a pressure great enough to restore the shaft 34 to a locking position. If the pressure rises, bellows 112 causes shaft 92 to move upwardly, pin 150 moving in a slot 151 in stem 93 of valve member 70; when the second level is exceeded the shaft will have moved so as to release locking balls 95 and the pin will have reached the end of slot 151 so that further movement compresses spring 153 and causes the valve member 70 to meet seat 57. If the pressure then rises above a third higher level, since the shaft 92 cannot move further upwardly, further contraction of the bellows causes resilient fingers 114 on adapter 110 to release the shaft 92; the valve is held closed by the pressure beneath it, until the pressure above it is raised to that value, when it is opened by the spring 153.  Instead of being responsive to pressures the valves may be controlled by a prescribed range of flow rates being departed from. Specification 1445603 is referred to.

In an A.C. switching arrangement semiconductor triodes 5, 6 are connected in parallel with a circuit-breaker 1 and in series with a second circuit-breaker 4 so as to perform the actual switching operations. During a closing operation circuit-breaker 4 is closed and then switches 2, 3 are closed to energize the grid circuits of the triodes 5, 6 which become conducting to respective half-cycles of current. The circuit-breaker 1 is then closed to take over the current carrying duty. During an opening operation the breaker 1 opens first and the current flows through the triodes 5, 6 until the switches 2, 3 are opened restoring the triodes to the blocked condition. The circuitbreaker 4 is then opened to relieve the triodes of voltage. The intervals in time between the opening of the switches and circuit-breakers 1 to 4 may be very short, allowing the triodes to be loaded in excess of their continuous rating. The circuit-breakers 1, 4 may be designed solely for their respective current carrying and voltage duties without consideration of breaking capacity. Fuses or circuit-breakers may be provided at 7, 8 and 9 to take over the disconnection duty under short-circuit conditions or one of the circuit-breakers 1, 4 may be arranged to perform this function. During a period of frequent opening and closing the switch 4 may remain closed.
