Abstract: The invention concerns a method and a device for directional drilling of a hole, in particular when drilling curved holes for mining, drift mining or similar, whereby a drill support is used in the form of a flexible continuous drill tube with a proximal end and a distal end, that at the end of the drill support distal end is connected a down hole assembly comprising a drill bit for forming a drill string, which is fed into the gradually forming hole. To avoid and minimize the occurrence of "stick slip" during directional drilling, according to the method, the drill support while drilling is taking place is held fixed at its proximal end against rotation outside the borehole and the rotating motion for indexing the drill bit around an axis extending in the direction of drilling is performed in the area between the drill support's distal end and the drill bit while drilling is in progress.

Abstract: Absorbent articles such as disposable diapers, incontinent pads, sanitary napkins and the like that have multiple layer absorbent cores that are suitable for acquiring and containing liquids in an especially effective and efficient manner. The absorbent core comprises multiple layers including a first layer comprising hydrophilic fibrous material and having an acquisition zone of a relatively lower average density than the other portions of the first layer so that it quickly acquires discharged liquids; a liquid handling layer comprising a resilient material that is moisture insensitive so as to rapidly acquire liquid into itself through the acquisition zone and distribute the liquid throughout the liquid handling layer to a storage layer and the first layer; and a storage layer comprising a combination of fibrous material and discrete particles of absorbent gelling material that contains and stores the liquids deposited onto the absorbent core and allows the liquid handling layer to be "drained" of the liquids it has acquired so that the liquid handling layer may have sufficient capacity to acquire and distribute subsequent loadings of liquids.

Abstract: A front leg (1) is formed of a linear support pole rising upright from a stationary stud (8) and a rear leg (2) is formed of a lower support pole (2a) extending along a diagonal line connecting the upper end portion of the front leg and the lower end portion of the rear leg and an upper support pole (2b) extending from the upper part of the lower support pole (2a) and arching upwardly and rearwardly. Further, an energy absorbing member (12) is bridged as a diagonal member between the upper end of the front leg and the lower end of the rear leg to constitute the leg structure. This leg structure serves to absorb impact energy by antiplastic deformation force that occurs when the rear leg (2) and the member (12) receive impact beyond a predetermined value and undergo plastic deformation, and supports the seat in a support posture at the time of normal use. This leg structure can be utilized as the leg structure of seats to be fitted not only in airplanes but also in automobiles, railway vehicles, and so forth.

Abstract: Retroreflective elements, such as cube-corner elements or right triangular prisms containing cube-corners, are arranged on articles to define separation surfaces between the elements; in another embodiment, the elements are truncated cube-corners incorporating similar surfaces on the elements themselves. If the surfaces are transparent they will transmit light through the article, rendering it partially transparent and partially retroreflective. The surfaces may be flat or curved. Standard grooving techniques may be employed to construct the elements, using mold cutting tools having flattened or curved tips instead of V-shaped tips; alternatively, electroformed molds may be lapped to include the shape required to produce surfaces. The elements and surfaces may be embodied in sheeting materials or internally illuminated signs.

Abstract: A microlithographic process of fabricating electronic components, such as, for example, integrated circuit chips and thin film read/write heads for computer disk systems, in which a laser is used to etch features defined by a mask. The laser is selected whose radiation will be absorbed by the workpiece being etched, and the masking material is selected so as to be highly reflective of the laser radiation. The masking material is patterned in a conventional manner so as to expcse the portions of the workpiece material to be etched. When the laser is directed to the workpiece, the laser radiation etches the portions of the workpiece not protected by the mask. A preferred process of scanning with a laser is disclosed. Etching may be improved if performed under a liquid transparent to the laser radiation.

Abstract: A collision detection method and apparatus is disclosed for detecting code rule violations in Manchester encoded data packets. The signals delta 0=S2n-S2n-1  delta 1=S2n+1-S2n  delta 2=S2n+1-S2n-1  sigma 0=S2n+S2n-1. are determined at time nT where S2n-1 and S2n are the Manchester code bit pair representative of the nth bit in a data stream having a bit period T. Processing of these signals permits the detection of most collisions since the Manchester coding rules are violated more than half the time in the signal formed by the colliding packets. To ensure 100% collision detection, a preamble using an intentional violation of the Manchester code in the pattern 10 11 01 10 is advantageously used in each data packet and a collision is signaled upon detection of two or more coding violations.

Abstract: An automated guided vehicle (AGV) control system which is downward compatible with existing guidewire systems providing both guidewire navigation and communication and autonomous navigation and guidance and wireless communication between a central controller and each vehicle. Vehicle steering and control includes autonomous guidance and navigation of the vehicle over paths marked by update markers which may be spaced well apart, such as fifty feet. The control system employs high frequency two-way data transmission and reception capability over the guidewires and via wireless communications. The same data rates and message formats are used in both guidewire and wireless communications systems. Substantially the same communications electronics are used for the central controller and each vehicle. Novel navigation and guidance algorithms are used to select and calculate a non-linear path to each next vehicle waypoint when the vehicle is operating in the autonomous mode. The non-linear path orginates with an initial direction equal to the heading of the vehicle as it enters the path and a waypoint heading defined as part of the message received from the central control system which plans and controls travel of each vehicle in the system.

Abstract: An actuator which includes a memory metal element, a substantially constant force counteracting spring, and an actuated element. The memory metal transforms from a martensite structure to an austenite structure at a known temperature. The martensite structure is more easily deformed than the austenite structure. The force applied by the counteracting spring is sufficient to deform the martensite structure throughout the transformation temperature range but insufficient to deform the austenite structure such that at least a portion of the memory metal strip undergoes a predetermined stroke in response to the transformation of the memory metal strip between the martensite and austenite states. The actuated element is connected to the memory metal element to move therewith. <IMAGE>

Abstract: A method and apparatus are provided for adaptively equalizing data signals in a communications receiver. An unequalized data signal is demodulated. The demodulated data signal is filtered in an adaptive equalizer (60) that initially updates adaptive filter coefficients using error signals derived from a first algorithm. A carrier lock signal is generated (62, 78) when a phase error of a filtered signal output from the adaptive equalizer reaches a threshold value. The adaptive filter coefficients are updated (74) using error signals derived from a second algorithm instead of the first algorithm in response to the carrier lock signal (72). The first algorithm is a self-recovering equalization algorithm such as the Constant Modulus Algorithm. The second algorithm can be a decision directed algorithm. Carrier phase is recovered without the use of a phase rotator or phase de-rotator, by locating the adaptive equalizer inside of the carrier recovery loop (56). The invention is particularly adapted for use in the recovery of multilevel amplitude modulated data, such as QAM data. <IMAGE>

The water vapour thus evaporated is removed through the spaces (18,28,10c) in the blowing-on hood (10). By means of the set of drying-gas jets (B1), the interior of the web (W) to be dried is also heated.
