Abstract: A shackle clamp assembly has one end configured as a cap for insertion on the end of a shackle bolt attached to a U-shaped shackle and second end configured as a loop for attachment around the U-shaped shackle. The cap has an aperture that aligns with a through-bore in the end of the shackle bolt. A pin is inserted through the aperture of the cap and the through-bore of the shackle bolt to retain the cap on the end of the shackle bolt. The cap abuts the nut threaded on the end of the shackle bolt to ensure that the nut does not become disconnected from the shackle bolt.

Abstract: A swivel pressure head includes a fixation mechanism detachably securing an upper housing to a lower housing. The upper housing includes an internal bore extending from a fluid inlet to an opening on a bottom surface of the upper housing. The lower housing includes a central bore. A pressure sleeve is disposed within the internal bore of the upper housing and within the central bore of the lower housing. A locking nut operatively engages the pressure sleeve and is configured to engage a swivel stem so that rotation of the swivel stem rotates the pressure sleeve. A packing assembly positioned in the internal bore of the upper housing fluidly seals between a wall of the internal bore and an outer surface of the pressure sleeve to direct a fluid flow from the internal bore of the upper housing through a fluid inlet and an internal bore of the pressure sleeve.

Abstract: Apparatus for rotationally locking the swivel of a drillstring during downhole backoff, directional drilling, and similar operations, and for continuous monitoring of the torque level in the drillstring. A first member has a collar which attaches to one side of the swivel, the collar having a main plate attached thereto and extending outwardly from the swivel. A second member is suspended from the plate, and has a set of jaws which can be closed to grip the swivel and thereby rotationally lock the swivel. A means for measuring forces between the first and second members is disposed between the first and second members, and in combination with appropriate processing and controls permits monitoring of torque on the drillstring while the drillstring is raised and lowered as desired.

Abstract: A suspended ceiling construction includes fill-in panels, diffusers and/or light fixtures which are retained in their openings by spring clips that have been pre-attached to the ceiling grid frame members. The clips bear against edges of the panels to keep them in place normally, but they can be deflected out of the way by pushing up on the panels when necessary. As the tips of the clips contact the frame members during deflection, they provide increasing resistance to further deflection.

Abstract: A lightweight interchangeable shield device to protect and prevent injury to individuals involved in baseball related sports activity. The shield device extends integrally from a seat between the legs of the individual protecting the crotch region from being hit with a baseball during practice. The seat can be configured as a closure lid for upright containers having an open end or can be of a contoured cushion configuration. The shield is adaptable to conform to other seat structures independently.

Abstract: A locking swivel apparatus is provided. The locking swivel includes an upper body portion having a counter bore about a cylindrical axis and a mandrel receivable in the counter bore. The apparatus further includes a locking arrangement, including at least one replaceable gear member, disposed to engage with the upper body portion and the mandrel. The locking arrangement is further disposed to selectively couple and decouple the upper body portion and the mandrel, such selective coupling and decoupling disposed to correspondingly constrain and allow relative rotation of the upper body portion and the mandrel about the cylindrical axis. Embodiments of the locking swivel include two replaceable gears disposed to selectively engage and disengage one another.

Abstract: A locking swivel apparatus is provided. The locking swivel includes an upper body portion having a counter bore about a cylindrical axis, a mandrel receivable in the counter bore, and a lower cap member threadably engaged with the upper body portion. The apparatus further includes an internal locking arrangement configured to selectively couple and decouple the upper body portion and the mandrel. The selective coupling and decoupling is disposed to correspondingly constrain and allow relative rotation of the upper body portion and the mandrel about the cylindrical axis. The apparatus still further includes a supplemental internal locking mechanism configured, upon engagement, to selectively constrain the upper body portion and the mandrel from reciprocating along the cylindrical axis. The engagement of the supplemental locking mechanism is operable to secure the upper body portion and the mandrel in a coupled position.

Abstract: Provided is a filtering system and method that incorporates a portable filter device. The portable filter has a front side and a back side. A medical gurney is positioned proximate the portable filter device. An air intake provided in the back side of the portable filter device and an air outlet diffusion plate provided in the front side of the portable filter device. A first filter is disposed across the air intake and a second filter is disposed behind the air outlet diffusion plate. Also provided is an air drawing device which draws air into the portable filter device through the first filter and sends air out of the filter device through the second filter. Filtered streams of air are then formed above and below a patient supporting area of the gurney, such that the filtered streams of air have a laminar flow. Rollers are provided for permitting the portable filter device to be moved across a floor surface.

Abstract: A system for powering components on an oil drilling or production platform utilizing a relatively inert fuel, the system including a first plurality of tanks which contain carbon dioxide in the liquid phase; a second plurality of tanks for receiving the carbon dioxide under pressure in the liquid phase and flowing the carbon dioxide into the second plurality of tanks into a high pressure gaseous phase. There is further included a third low pressure tank which would receive the high pressure carbon dioxide from the second plurality of tanks into the tank under a substantially low pressure within the third tank. The third tank would be equipped with a means for flowing the carbon dioxide into a component such as a pump or engine so that the carbon dioxide serves as a fuel for driving the component and allowing the component to undertake a particular task on the rig floor such as the testing of lubricators grease units or an engine for driving certain functions of the rig.
