A method and system for controlling the descent of a moveable element pivotally attached to a rigid structure. The moveable element is pivotally attached to the rigid structure, and is then pivotally connected to a compressible strut, which is pivotally attached to a linkage pivotally connected to the rigid structure. The descent of the moveable element is controlled using a microcontroller and a motor attached to the linkage, and the control path for the linkage is selected based on a comparison of the angle between the linkage and rigid structure and the angle between the moveable element and the rigid structure.

Methods and apparatuses for inserting flexible bags and other liners into open packaging containers. One or more engagement heads engage and position the flexible liners in preparation for their insertion into open containers using an insertion assembly. One or more of the engagement heads are preferably made with vacuum heads that are movable to open the liner for the insertion assembly. A cuffing assembly can be included for cuffing the open end of the liners over the top edges of the open containers. Clamping assemblies can be included on the cuffing assembly to facilitate holding the liners during insertion and cuffing. The use of an engagement assembly, insertion assembly, and cuffing assembly which are independently driven helps to provide greater speed and operational flexibility.

An apparatus and corresponding method for cleaning curved sheets of glass. The apparatus indexes glass sheets in a non-continuous manner through at least a pre-washing zone, a washing zone, a rinsing zone, and/or a drying zone. The glass sheets proceed through any or all of these zones in a substantially upright orientation in certain embodiments. In at least one of the wet zones, a robot arm manipulates a plurality of spray nozzles so as to follow the contour of at least one major surface of the glass. The nozzles may be manipulated back and forth across the surface in order to rinse and/or wash the glass. A similar manipulation of air knives along the contour of the glass sheet may be utilized in the drying zone.

The present invention provides systems utilizing fiber optics for monitoring downhole parameters and the operation and conditions of downhole tools. In one system fiber optics sensors are placed in the wellbore to make distributed measurements for determining the fluid parameters including temperature, pressure, fluid flow, fluid constituents and chemical properties. Optical spectrometric sensors are employed for monitoring chemical properties in the wellbore and at the surface for chemical injection systems. Fiber optic sensors are utilized to determine formation properties including resistivity and acoustic properties compensated for temperature effects. Fiber optic sensors are used to monitor the operation and condition of downhole devices including electrical submersible pumps and flow control devices. In one embodiment, a common fluid line is used to monitor downhole parameters and to operate hydraulically-operated devices. Fiber optic sensors are also deployed to monitor the physical condition of power lines supplying high electric power to downhole equipment. A light cell disposed downhole is used to generate electric power in the wellbore, which is used to charge batteries.

An electro-static discharge shield on the external non-finger contact surface of a switch makes a contact between the shield itself and the grounded chassis. Since the shield has substantially lower resistance than the surface or inner circuitry of the switch, external electro-static discharge introduced on the surface of the switch flows through the shield to ground via the grounded chassis to prevent destruction or interruption of the circuit.

An X-ray imaging apparatus comprising an X-ray source, a collimator, and an X-ray scatter detector. The X-rays are directed toward an object to be imaged where the collimator and detector are located between the source and object. The X-rays striking the object produce back scattered X-rays which are directed back through the collimator to the detector and an image is produced.
摘要:
A tripping object including an object including a shape memory material and being stable in a second shape complementary to a landing feature and a first shape non-complementary to the seat, the object being transitioned from the second shape to the first shape upon being triggered. A method for operating a well including dropping a tripping object including a shape memory material on a landing feature in the well, and triggering the object to transition from a second shape to a first shape.
摘要:
A movable table assembly comprising a base portion and a table support each having angular connecting nub with an interior cavity to enable fastening inline with a support leg. The preferred assembly utilizes a base portion, a support leg, a table support, and a table. The base portion and table support being generally planar and having a first side and second side defined by an edge around a perimeter. The support leg coupled between the base portion and table support to generally provide a movable work surface, wherein the table and base portion are generally positioned parallel to a ground surface despite the angular connection.
