Abstract: A wireline apparatus for deep well measurements in a borehole being drilled includes a drill string having multiple drill pipe sections connected end-to-end, with at least one of the drill pipe sections being electrically conductive and isolated to provide an electrode section. A nonmagnetic drill pipe section is connected in the drill string below said electrode section, and a hydraulic motor having a rotatable drill bit carrying a drill bit instrument sub having a magnetic field sensing instrument package is connected to a lowermost end of the drill string. A wireline locatable within said drill string incorporates an electrode locatable within the drill pipe electrode section, and carries at its distal end a wireline instrument package that is locatable within the nonmagnetic drill pipe section to receive data representing magnetic field data from the magnetic field sensing instrument package.

Abstract: An electronic circuit including a microchip for use as an intelligent user interface also comprises touch sensor technology that differentiates between proximity and physical contact events to activate and control various loads including light bulbs, products with radio frequency circuitry or electric motors. An input to the microchip is connected to a switch or sensing structure that does not form a serial link between the power source and the load. The electronic circuit controls various functions in response to user actions including automatic delayed shut-off functions, find-in-the-dark indicator and power source level/product state indications. The microchip allows the user to select specific functions based on the time duration of activation signals, the time duration between activation signals and the number of activation signals at the input.

Abstract: A semiconductor chip has at least two DFB etched facet laser cavities with one set of facets with AR coatings and a second set of etched facets with HR coatings that have a different relative position with respect to the gratings. This creates a difference in the phase between each of the etched facets and the gratings which changes the operational characteristics of the two laser cavities such that at least one of the lasers provides acceptable performance. As a result, the two cavity arrangement greatly improves the yield of the fabricated chips.

Abstract: A photonic device incorporates an epitaxial structure having an active region, and which includes a wet etch stop layer above, but close to, the active region. An etched-facet ridge laser is fabricated on the epitaxial structure by dry etching followed by wet etching. The dry etch is designed to stop before reading the depth needed to form the ridge. The wet etch completes the formation of the ridge and stops at the wet etch stop layer.

Abstract: A reception coil maintaining element for an MR-imaging system includes two phase-controlled multi-element arrays of an RF multi-channel surface reception coil. Both of these phase-controlled, multi-element arrays have a reception surface including a center having a longitudinal axis that crosses that center. Each of these multi-element arrays is arranged on an arm which can pivot about a common pivotable axis. A vertical first plane is parallel to this pivotable axis. A vertical left plane extends along the longitudinal axis of the center of the left reception surface of the left multi-element array. A vertical right plane extends along a longitudinal axis of the center of the right reception surface of the right multi-element array. Both of these vertical left and right planes have approximately the same spacing with respect to the vertical first plane of the pivotable axis where the reception coil maintaining element in accordance with the present invention is in its operational state.

Abstract: A module for controlling power supply to a load in a product which includes a microchip, and an electromechanical switch and a proximity/touch sensor connected to the microchip, preferably to the same input. The switch is primarily used to activate or deactivate the load and the proximity/touch sensor to vary the effect of operating the switch, or to control additional functions such as the activation of a signal, typically a light signal, which helps to locate the product, particularly in the dark, and to vary the duration of an automatic time-out period at the end of which the load is deactivated.

Abstract: A bird toy for stimulating a foraging instinct by surrounding a treat on a platform on a main body with one or more substantially transparent rings rotatable and vertically slidable on the main body. In one or more rotative positions of the ring or rings turned by a pet bird, the ring or rings are allowed to shift vertically to make the treat accessible. A bottom platform allows a more difficult test, requiring the bird to lift the ring or rings to expose a treat on the bottom platform after rotating the rings to the correct position allowing the rings to be lifted.

Abstract: A release mechanism for use with an explosives disposal robot having an elongated boom includes a latch member secured to an outer end of the boom, the latch member having a fixed portion and movable latch or lever members. A flexible strap extends between the lever members, with one end being attached to one of the lever members and the other end being releasably attached to the other lever member. When the other lever member is moved to a release position the other end of the strap falls from the other lever member so as to release, for example, a firing line cradled in the strap. The one lever member can be actuated by way of a remote controlled solenoid connected thereto via a flexible cable or by way of an elastic member connected thereto.

Abstract: A technique known as checkpointed early load retirement, combines register checkpointing load-value prediction to manage long-latency loads. When a long-latency load reaches the retirement stage unresolved, the processor enters Clear mode by (1) taking a Checkpoint of the architectural registers, (2) supplying a load-value prediction to consumers, and (3) early-retiring the long-latency load. This unclogs retirement, thereby “clearing the way” for subsequent instructions to retire, and also allowing instructions dependent on the long-latency load to execute sooner. When the actual value returns from memory, it is compared against the prediction. A misprediction causes the processor to roll back to the checkpoint, discarding all subsequent computation.

Abstract: A downhole source of electrical power for drilling tools is driven by the rotation of a drillstring or, if the drillstring is not rotating, by the rotation of a drilling sub. The source consists of an alternator having a rotor made up of a series of coils that are mounted on, and spaced around the circumference of, a rotating drilling sub, and a stator made up of a multiplicity of permanent magnets also spaced around the circumference of the drilling sub. The stator is mounted on the drilling sub by means of bearings and incorporates a counterweight that holds the rotor relatively stationary with respect to the sub and with respect to the coils, so that rotation of the sub, either by rotation of the drillstring or by rotation of a drill motor in the drilling sub, produces relative rotation of the rotor and stator to generate an AC electrical output.

Abstract: A system comprises alternative processing sections for use in the further processing of products. A separator, at which a transport section is divided into several alternative transport sections for the further processing of products in processing stages, is provided. A sensor, that detects the phasing of the products, is located upstream of the separator. A request from the sensor acts on a drive which actuates the separator through a control device. A further sensor, which detects the product phasing, is located on each of the at least two transport sections. This further sensor is connected to a drive for the processing stage served by respective ones of the separate transport sections. The drive of each such processing stage is controlled independently of the drive for the respective transport section by a suitable control unit which takes into consideration the detected product phasing for the associated transport section.

Abstract: Phosphine gas is generated by agitating a reaction mixture of a metal phosphide and water with agitation air in a reaction pot of a phosphine gas generator. The resulting phosphine gas is then diluted with dilution air to produce a fumigant phosphine gas which is directly delivered to a commodity for fumigation. The reaction pot does not have any rotating means such as agitators, rotors, or stirrers. The generator provides on-site generation of phosphine gas in a rapid manner improving the fumigation efficiency for a commodity, such as grain, preferably contained within a storage structures, such as a grain silo. The generator has a built in deactivation system for the unused metal phosphide and phosphine gas.

Abstract: A rugged, adjustable optical alignment device well suited for use as a pistol rear sight is adapted for use in a dovetail, as is customarily seen on the slide of an automatic pistol. The sight assembly includes a rear notch, but could just as easily include a peep aperture or other optical alignment structure. The rear sight provides an easy click-detent adjusting mechanism for horizontal translation of the notch, as well as a second click-detent mechanism for vertical translation of the structure defining the notch, thereby providing adjustments for windage and elevation. A base hingedly supports a vertical tilt member. A horizontal slide member mounted on the rear of the vertrical tilt member is horizontally translatable by adjustment of a windage adjustment screw.

Abstract: Presented is a device having a unitary body molded from synthetic resinous material and including a base member having a central mounting recess on its back side for receiving the mounting stud of a suction cup. On its front side the device is provided with a multiplicity of rows of spaced elastically resilient “prongs”, or a multiplicity of “tuft” like projections each formed of many different thin filaments, or a multiplicity of “rod” like projections the distal ends of which are semi-spherical or “rounded” and useful for applying deep massaging pressure to the skin for stimulation thereof. Integrally formed on the base member are mounting flanges having integral mounting lugs and mounting apertures for detachably interconnecting one such device to a similarly constructed adjacent device to selectively form a specifically arranged configuration or array embodying a multitude of the devices.

Abstract: The invention relates to a method for reducing register errors on a web of material (04) moving through the printing nip of a multicolor web-fed rotary press, comprising the following steps: providing a portion between an area of the web of material (04) located between the two lateral edges of the web of material (04) and areas in the vicinity of the lateral edges of the web of material with a deformation relative each other in a direction perpendicular to the plane of rotation of the web of material (04) subject to a register error occurring in the direction of rotation of the web of material (04).

Abstract: A bucket clamp assembly receives and supports a five gallon bucket securely in place while the user mixes slurry-like products. The bucket is preferably inserted into the clamp assembly on the ground. The user places the bucket on a base plate between a fixed front support and an opposing hinged rear support and firmly against the hinged rear support, thereby raising a lever arm operating the hinged support to an open position. The user then presses her or his right foot firmly down on the exposed upper surface of the base plate and places the left foot across the lever arm. The clamp is thereby securely pressed to the ground using the worker's body weight. Further pressing the left foot down across the lever arm also forces the hinged rear clamp support surface to swing distally or forwardly, thereby firmly squeezing the sides of the bucket against the opposing, fixed clamp support, securing the bucket in place for safe and efficient mixing.

Abstract: A solid-state semiconductor device operable without loss arising from junction-to junction (e.g., source-to-drain) leakage current includes a movable MEMS switch or relay armature structure carrying at least one electrical contact corresponding to a semiconductor device junction. The switch or relay armature is movable from a first position corresponding to a first switch state to a second position corresponding to a second switch state. The semiconductor device also includes an actuation circuit configured to act on the cantilever switch, changing the switch from a first contact-conducting state to a second non-contact-conducting state by physically separating the switch's electrical contact from the semiconductor device junction, thus eliminating the conductive path for leakage current losses.

A first inking roller, which can rotate inside the trough, extends over a first width section of the trough and the forme cylinder. A second inking roller, which can also rotate inside the trough, extends over a second width section of the forme cylinder or the trough.

Abstract: A cylinder, having a cylindrical body which is rotatable about a cylinder axis of rotation, is usable to process flat material. At least one group of a plurality of tools are distributed around the periphery of the cylinder body in a homogeneous manner. These tools are able to perform a working movement with respect to the cylindrical body and are coupled to a control device which effects that working movement. A first cam plate is traced by the control device of each tool group. A rotatable cover disk is also traced by the control device of each tool group. The cover plate is rotatable and is coupled, for its rotation, to the rotation of the cylinder. The cam plate has a peripheral section that controls the tool working movement, in cooperation with the control device.
