Abstract: The downhole lock assembly comprises a lock mandrel (10) connected to a running tool (11). The running tool holds an inner mandrel (13) located within the lock mandrel (10) in a position which allows lock-out keys (20) of the lock mandrel (10) to remain within the outside diameter of the lock mandrel body (12). Shear pins (34) are adapted on downward jarring against a landing nipple to expand the keys (20) and shear pins (33) are adapted on upward jarring to release the running tool. The running tool has a 'tell-­tale' collet (30), connected to it by a shear pin (32), to indicate that the lock mandrel is correctly set in the landing nipple, said collet being adapted when the running tool (11) is released from the lock mandrel (10) after setting the lock to disengage intact from the lock mandrel (10) if the lock-out keys (20) are correctly set and to foul the inner mandrel and shear the shear pin (32) if the lock-out keys are incorrectly set. The inner mandrel (13) is resiliently urged in an upward direction, i.e. in the direction of flow from the well, to actuate the lock-­out keys (20) to set the lock, and latch means (22) is provided to hold the inner mandrel in a downward disposit­ion against its resilient means prior to setting the lock.

Abstract: Laser welding of an outer sleeve 14 to an inner fiber ferrule 12 is expedited by, first, machining a thinned region 18 in the outer diameter of the sleeve. After the ferrule has been inserted in the sleeve, the thinned region permits the laser to fuse through the sleeve and melt part of the ferrule, as is required for laser welding of ferrule for the sleeve. The thinned region is preferably made by using a rotary cutter to cut an axially extending slot in the outer sleeve, which permits a succession of laser welds 21 in the axial direction in the slot. In a preferred embodiment, thinned regions 18, 19 are made on opposite sides of the outer sleeve, and laser welding is performed simultaneously on both sides of the sleeve so as to avoid distortions caused by thermal stress asymmetries.

Abstract: A computer connected to an ISDN switch via an ISDN digital subscriber line, has shared call appearances with a number of telephone stations connected to the switch and on the basis of shared call appearance associated messages from the switch, controls the forwarding of calls directed to the stations with which it has a shared call appearance. The associated messages are interpreted by the computer, which generates station status information. The computer responds to messages associated with predefined ones of the stations to select an alternate destination for the call and to transmit ISDN messages to the switch to cause the call to be forwarded to the selected alternate destination. Calls may be forwarded depending on call type, called number or other criteria. The computer responds to calls forwarded to it in the event that an associated station is busy and connects a holding party to the principal phone when the principal phone is no longer busy. The computer may be connected simultaneously to several ISDN switches via ISDN subscriber lines to receive shared call appearance associated messages from the several switching systems and forward calls for a telephone station connected to one switch, to a telephone station connected to another switch.
