There are many natural pauses during rotary drilling operations where a portion of the drill string remains stationary. Pauses include drill pipe connections, circulating time, and fishing operations. These pauses are used to obtain formation evaluation measurements that take a long time or that benefit from a quiet environment, as opposed to the naturally noisy drilling environment. Various techn...

The decorative layer (5) along the cutting line (13) is first removed from the carrier foil by means of a laser beam (12). The carrier film in the track thus formed is mechanically cut through by means of a blade (3). An Independent claim is also included for an apparatus for carrying out the above method which is characterized by the following facts: (a) the laser unit (11) and the blade (3) are ...

The device has a laser and a focusing device to produce a pulsed laser beam, a holder for a work piece and a drive controlled by a control device to move the workpiece or the laser transverse to the laser optical axis. The laser beam is controlled to remove single layers in several parallel or overlapping lines to form a kerf over the whole width to be removed. The laser is guided over a narrower ...

A probe (20) such as an endoscope equipped with a biopsy needle is guided to a target in or adjacent to the respiratory system. The position of the probe is monitored and a representation (26') of the probe is superposed on a previously acquired image of the respiratory system and adjacent tissues. Artifacts caused by motion due to respiration are suppressed by monitoring the respiratory state of ...

Dual glass fibers can be processed into coherent webs and felts by first blending the dual glass fibers with an equal or greater amount of uncrimped fibers. Optionally, other crimped fibers can be added without significant impact on processibility.

The invention relates to a starting battery of optimized starting dynamics, arranged in a plastic container, with outline dimensions specified by relevant standards provided with the required negative and positive plate stacks, plate straps, plate terminals and poles, with a connected electric and electronic control unit. The essence of the invention lies in that the plastic battery container (1) ...

The valve consists of a strip -1- onto which two coplanar strips -3, 4- are welded separated by an opening -5-. Production of the valve takes a strip -11- onto which two strips -12, 13- are welded separated by a space -5-. The valve obtained -16- is welded onto a laminar -17-, which forms part of the inflatable, with a hole -19- which has to coincide with the valve opening -5-. Next the first shee...

Multiword information is encoded as based on multibit symbols in relative contiguity with respect to a medium, whilst providing wordwise interleaving and wordwise error protection code facilities. This may provide error locative clues across words of multiword groups, that originate in high protectivity clue words and point to low protectivity target words. The clue words may have a first uniform ...

The invention concerns a tyre comprising a tyre tread (3) consisting of two circumferential layers (31, 32) whereof the reinforcement filler is mostly a non-conductive filler, each layer containing a circumferential insert (11, 12) of conductive mixture, having on the contact wall (310) between the two layers (31, 32) a circumferential surface, the first and second layers (31, 32) having on said w...

The invention concerns a tyre comprising a tyre tread (3) made up of two non-conductive layers (31, 32), each layer (31, 32) contains a circumferential insert (11, 12) of conductive mixture, at least one of the layers being provided with an insert, having, viewed in transverse cross-section, a surface S with two bases and whereof the first base, on the contact wall (310) between the two parts, has...

A method for selectively wet etching material during the formation of a field emission display device. In one embodiment, the selective wet etching method comprises immersing, in a fluid bath, a structure having a conductive row layer and a resistor layer (206). The structure further includes a pad area (204a, 204b). In this embodiment, the fluid bath includes an organic-acid etchant (210). The pr...

The disclosure describes a polyester film for sublimation-type thermosensitive transfer, comprising a polyester film having the degree of planar orientation of 0.145 to 0.169, and a coating layer formed by applying a water solution or a water dispersion composed of at least one water-soluble or water-dispersible resin selected from the group consisting of urethane-based resins, polyester-based res...

Components of composite material are made from pre-impregnated or laminated sheets (1) by inserting the sheets in a closed moulding cavity (2) defined between at least two adjacent half-moulds (3, 4) and following spreading of a separating agent, wherein at least one half-mould has a die (5) of a shape matching that of the component to be produced, and then by introducing into the moulding cavity,...

A method and apparatus for inspecting articles such as printed circuit boards doubles the transport rate for the article under inspection, and modifies the manner in which acquired video images are processed to account for this change in rate. Primarily, this involves two modifications to existing video processing systems including a change in synchronization for obtaining the frames which are to ...

Polyurethane foam of low thermal conductivity is prepared by employing carbon dioxide as a blowing agent, preferably in combination with a halogenated compound, typically a halocarbon or halohydrocarbon such as monofluorotrichloromethane or 1,1-dichloro-1-fluoroethane, and incorporating in the foam a carbon dioxide-reactive reagent. Sodium hydroxide and soda lime are illustrative carbon dioxide-re...
