Abstract: ABSTRACT           A holder for a pick and the combination of a pick and holder.   The pick 1 has a shank 4 received in a socket 6 of a holder 2.   The holder 2 carries in its socket 6 a tubular spigot 13 which mates in sealed manner with a coupling socket 15 in the pick shank to provide communication for water flow from a supply passage 16a through the pick 1 to outlet ports 12.   A shoulder 8 on the spigot 13 abuts a sealing ring 18 in the coupling socket 15 to retain the pick in the holder and permit relative longitudinal displacement therebetween.   Carried by the tubular spigot 13 is a valve having an actuating rod 22 which extends through the bore of the spigot.   A valve head 24 on the rod 22 is seatable on a shoulder 23a to close off water flow through the bore of the spigot.          The end 26 of the rod 22 abuts the pick and during displacement of the pick into its holder in response to cutting engagement of the pick with the mineral, the valve head 24 is displaced to permit water flow to the ports 12.  When the pick disengages from the mineral, water pressure on the pick and valve head 24 closes the valve head to seal against the shoulder 23a.

Abstract: ABSTRACT OF THE DISCLOSURE      A  connecting  device  for  connecting  together  tubular members is comprised of a resilient sheet member in the form of a coil  having  at  least  partially  overlapping  surfaces.   The inner diameter of the sheet member coil is less than the outer diameter of the members to be joined.   A layer of heat sensi-tive  adhesive  bonding  material  is  provided  over  the  inner surface and subsequently after the formation of the connection on  the  outer  surface  of  the  sheet  member  coil.   The  sheet member  coil  is  expanded  to  a  larger  diameter  against  the resiliently  inwardly  directed  force  of  the  sheet  member  and held  in  the  expanded  condition  by  heat  sensitive  adhesive bonding material.   The expanded larger diameter is of a suffi-cient diameter to receive the ends of the members to be join-ed.   Once the members to be joined are inserted into the coil, the sheet member coil may be heated whereby the heat sensitive adhesive bonding material  melts  allowing  the sheet member to contract  inwardly  forming  a  tight  bond  between  the  inner surface of the sheet member and the members being joined.   The connecting device may be utilized to connect a tubular member and  an  expandable  tubular  member.   The connection  formed by heating in such case results in the sheet member coil assuming a minimal degree of frustro-conical shape with a limited flow of the adhesive bonding material from the area over the expand-able unit to the area over the tubular member.   After applica-tion  of  a  second  layer  of  heat  sensitive  adhesive  bonding material  on  the outer  surface of the sheet member coil,  the joined expandable unit to the tubular member is provided as an assembled unit ready for field application.   The device may be utilized for repairing tubing.

Abstract: ABSTRACT          The present invention is a method for improving well cementing.  A fluid such as drilling mud or preflush fluid is oscillated in the annulus prior to introduction of cement slurry into the annular interval to be cemented.  The fluid is oscillated by changing its direction of flow at least twice The oscillatory flow of the fluid flushes gelled drilling mud and filter cake from the annulus more effectively than conventional unidirectional flow.  Following the oscillatory phase, cement slurry is pumped into the annular interval to be cemented, thus displacing the fluid, and is allowed to set.          The fluid can be oscillated in the annulus either before or after the cement slurry is introduced into the casing.  A selective check valve is also described which permits all fluids to flow in the forward direction out of the casing and into the annulus and which permits all fluids other than cement slurry to flow in the reverse direction out of the annulus and into the casing.

Abstract: OFF-LINE NOTIFICATION AND COMMUNICATION NETWORK     ABSTRACT            The present invention relates to improvements in communica-tion procedures, especially in networks which include at least one device which is capable of being manually switched to an off-line condition.  In accordance with the invention, when a switch on such a device is thrown to the position which would place the device in an off-line condition, the device formulates and transmits a message to indicate that it is going to a temporary off-line condition.  This message can be used at other devices which are connected in the communication network.  Such a message can be employed at a network focal point for maintaining such a device in a polling loop regardless of the fact that the device may, for some period of time, fail to respond to any polls.  Such a message can also be employed in any device which was in active communication with the device at the time it was placed in the temporary off-line condition to queue a restart request.  In accordance with the invention, when the device which had been placed manually in an off-line condi-tion, is again restored to the on-line condition, it will be in a condition to respond a poll from the network focal point.  When it so responds to the poll, the network focal point is informed that the device is again capable of communicating, and any device which has a restart request pending for the device can enable the restart request.
