Abstract: A lenticular images is attached to a thermoformed container during the thermoforming process by pre-forming the lenticular label and low temperature adhesive material that may fuse to the thermoformed plastic.

Abstract: A drilling fluid has a redispersible polymer powder introduced as a water dispersion that is capable of providing a deformable latex film on at least a portion of a subterranean sand formation and which inhibits or controls fluid loss and acts as a sealing agent when used to drill in sand formations for hydrocarbon recovery operations. The redispersible polymer powder may be made by drying the emulsion in which they are formed and then grinding into a powder or by spray drying. The polymer particles of suitable size precipitate or collect or assemble onto the pores of a subterranean sand formation to at least partial seal the formation with a deformable polymer film.

Abstract: Described in this application is a method of making a continuous lenticular image label web and a process for making a plurality of lenticular labels using a continuous lenticular image label web. In addition, a continuous lenticular image label web is described and detailed. Several advantages accrue from the methods described, including reduced time and cost to manufacture lenticular image labels. Advantageously, on-serting of lenticular labels is not required.

Abstract: A device for allowing a rotating plasma arc to perform cutting or welding operations inside tubes with small inside diameters by being attached to existing plasma arc power sources where in the speed and axis of rotation of the arc are controlled by the device, and the components of the device in proximity to the plasma arc itself are protected by the ceramic composition of the device and an inert gas shield.

Abstract: A multipart photosensitive element having a predetermined saturation density including at least two partial record portions for forming a full record, each partial record portion controlling a preselected density range of the full record; all of the partial record portions combining to produce the predetermined saturation density of the full record; at least one of the partial record portions including a fixed contrast emulsion and at least one of the partial record portions including a variable contrast emulsion for varying the contrast of that partial record portion over its preselected density range, each of the variable contrast emulsions being photoresponsive in a different spectral region from the other variable contrast emulsions in the other partial record portions for independently selectively varying the contrast in each of the partial record portions including a variable contrast emulsion.

Abstract: A multipart photosensitive element having a predetermined saturation density including at least two partial record portions for forming a full record, each partial record portion controlling a preselected density range of the full record; all of the partial record portions combining to produce the predetermined saturation density of the full record; and each partial record portion including a variable contrast emulsion photo-responsive in a different spectral region from the other emulsions for independently controlling contrast in the preselected density range associated with the partial record portion.
