Abstract: A flex circuit blind attachment apparatus is provided and includes a plate, a fastening member affixable to the plate and configured to draw the plate toward and away from a circuit board and jaws supportively disposed on the plate. The jaws are configured to be opened with the plate being drawn toward the circuit board such that a pin of a flex connector to be connected to the circuit board is released by the jaws following disconnection of the flex connector and the circuit board. The jaws are also configured to capture the pin with the plate being drawn away from the circuit board prior to connection of the flex connector and the circuit board.

Abstract: An arrangement for the insertion, retention and extraction into and from a motherboard back plane of at least one card-let printed circuit board without protective hardware, in order to be able to ensure the accurate alignment between mating connectors of these components. Furthermore, provided is a method facilitating the insertion, retention and extraction of a card-let printed circuit board of the type described, by utilizing the inventive arrangement.

Abstract: A printed circuit board top side mounting system is presented and includes a printed circuit board having a primary side and a secondary side. The printed circuit board top side mounting system also has a surface member that has a point with a generally constant distance in relation to the primary side. The printed circuit board top side mounting system further includes a standoff with a elongated shape which has a predetermined set dimension that includes the constant distance disposed in going through a slot in the printed circuit board. The standoff further includes a first end disposed to fixing the first end rigidly on the printed circuit board and a second end disposed in connecting rigidly to the surface member.

Abstract: A well tubing includes an insert nipple for receiving a hold-down projection of an insert pump. The tubing includes a tubing collar threadingly interconnecting the upper end of the insert nipple with the next upper tubing section. The tubing collar includes a tapered inner bore which becomes progressively larger in cross-section in the upward direction to provide, around the outside of the hold-down projection, a space of gradually enlarged volume for receiving debris as the insert pump is lifted from the well tubing, thereby preventing the pump from becoming stuck.

Abstract: An indicating device for repeatedly indicating variation in the load on a part such as a polish rod of a pump is disclosed. The indicating device includes an indicator for providing an indication when current flows through the indicator, a switch for moving between an opened and a closed position and for permitting current to flow through the indicator when the switch is in one of the open and closed positions, and reciprocating moving means for reciprocally moving in response to reciprocating movement of the part and for moving the switch to the one of the open and closed positions once during each cycle of the reciprocating movement of the reciprocating moving means. The indicator thus provides the indication once during each cycle of the reciprocating movement of the part and thus repeatedly indicates reciprocating movement of the part.
