Abstract: A computer automatically reads each object in a metadata that is descriptive of a database. Then the computer automatically applies a number of rules, to check if the object triggers a rule. If so, then the computer automatically changes the metadata as per an action identified by the triggered rule. After all rules are applied to the object, and after all objects in the metadata are processed, the resulting metadata is used to change the database's structure. The objects may be read from the metadata in an order (e.g. hierarchy) specified in meta-metadata that is descriptive of the metadata.

Abstract: A system and methodology facilitates use of a diverter latch assembly in cooperation with a lateral wellbore. The diverter latch assembly comprises an upper latch assembly coupled with a lower latch assembly via a swivel. The upper latch assembly also comprises a releasable latch positioned to engage a tieback receptacle located in the well. The swivel and the releasable latch are designed to enable rotation of the releasable latch relative to a tubing of the lower latch assembly during release of the diverter latch assembly from the tieback receptacle. The rotational release system helps provide controlled release and withdrawal of the diverter latch assembly while reducing risk of damage to the diverter latch assembly or other downhole components.

Abstract: A device is configured to inject signals onto a medium made up of conductors and a reference plane. Transformers inject the signals onto the conductors by orthogonal modes. Differential mode chokes each include one input and two outputs. The input is connected to one end of a secondary winding of one of the transformers, or one of the outputs of another one of the chokes. The two outputs are connected to either the inputs of two others of the chokes, the input of another one of the chokes and a conditioner of one of the conductors, or conditioners of two of the conductors. The number of chokes depends on a number of non-differential modes used. The injections that use the chokes are injections selected from between pseudo-differential injections, injection in common mode, or a combination of pseudo-differential injections and injection in common mode.

Abstract: A device for demolding negatives in plastic injection, which is coupled to means for ejecting a plastic injection mold. A guide bushing can be attached to the die plate of the moveable part of the mold, inside which extends a counter-mold which molds the negative and is formed by a guide runner and a head that can be lowered to demold the negative. The guide bushing contains a projection which pushes against the side of the head as the counter-mold moves forward, so that the head is lowered sideways and the negative is released.

Abstract: A stand-alone, rigid lacrosse pocket is formed from a piece of mesh netting that is shaped to exhibit a desired pocket contour. Once shaped, a coating of stiffening material is applied to the netting and embeds within the shaped mesh netting to “fix” the desired pocket contour and form a rigid lacrosse pocket. The rigid lacrosse pocket is thereafter attached to a conventional lacrosse head, using the same stringing technique as commonly used to attach the mesh netting to the head. Advantageously, by pre-fabricating the lacrosse pocket, the need to “work” the netting into the desired shape is eliminated, and a player can quickly and easily change pockets as necessary. A method of fabricating the stand-along, rigid lacrosse pocket is also disclosed.
