Abstract: A device for drilling holes (1) in the crust of the earth, especially for drilling oil wells, wherein a rotary bit (2) is fitted in a drill string (4), within which drilling fluid is pumped downwardly and, upon return, conveys cuttings to the surface. A piston (5) is mounted on the drill string (4) above the bit (2) and adapted to form a sliding seal against the wall of the hole (1). A seal (8) is mounted above the piston (5) within the hole (1) and adapted to seal against the wall of the hole (1), against the drill string (4), against a return line (6) adapted to conduct drilling fluid with cuttings from the under side of the piston (5) to the top of the seal (8), as well as against a pipe (9) communicating with a pump (10) adapted to pump liquid in between the seal (8) and the piston (5), whereby liquid pressure acting against the upper face of the piston (5) urges the bit (2) against the bottom of the hole (1).

Abstract: The invention relates to binding adapter plate for intermediate placement between the front and/or rear jaws of a ski binding and a ski. The binding adapter plate includes holes in the form of cylindrical bores which are dimensioned to receive fasteners for attaching the binding adapter plate and ski binding to the ski. An inner portion of the plate being movable relative to an outer frame portion of the plate when the ski flexes to relieve stress.

Abstract: An oil removal device for separating floating oils from water or water-based liquids. A rotating disk lifts viscous oils frown the water or water-based liquid. The oil is removed from the disk by wiper blades on either side of the disk on the downward part of the disk's travel. The oil then falls into channels and is channeled into a storage container. A support frame comprising a base and a center post attached to the base is connected to and supports the disk, wiper blades and channels. A gravity separating chamber could be used in place of the storage container. Water collected by the disk is diverted from the oil by a small-scale gravity separator module. The gravity separator module includes a weir having a gap or space at the bottom to separate the water from the oil.

Abstract: A method for fixing a stopper ring to the outer periphery of the spigot of a cast iron pipe for preventing separation of the pipe from another pipe. A single or plural annular grooves are formed on the inner periphery of the stopper ring, and a brazing filler material is fitted in the annular groove. The stopper ring with the annular groove in which is fitted the brazing filler material is fitted on the spigot of the pipe. Subsequently, the pipe is ferritically annealed and the stopper ring is simultaneously brazed to the spigot by the heat of annealing.

Abstract: A ski binding including a rocking anti-friction device for cooperating with a base plate to maintain the level of friction between the ski boot sole and the sole holder, as the ski boot is laterally released from the ski binding.

Abstract: An intercommunication system for transmitting signals through a door, and having piezo transducer devices mountable on each side of the door, a matrix of analog switches connecting the piezo transducer devices to the input and output of a bridge amplifier, and a TALK switching device which controls which piezo transducer device is connected to the bridge amplifier through the analog switches as a speaker or as a microphone.

Abstract: The invention relates to a toe piece for an automatic release ski binding. The toe piece is comprised of an upper housing and a base plate which is connected at one end with the upper housing. The upper housing and the base plate are additionally connected by at least one connecting element. In order to allow automatic adjustment of the sole holder to different heights and a reverse release, at least one end of the at least one connecting element is journaled either in the upper housing and/or in the base plate, with the intermediate placement of a resilient material. Alternatively, the connecting element itself is constructed of resilient material.

Abstract: A container, for holding consumable substances, having a plurality of closures adapted to restrain the contained substances and dividing walls to divide the container into a plurality of substance-holding compartments, each compartment being associated with one closure respectively.

Abstract: A method of bonding glass-based optical elements comprising the steps of positioning a first glass-based optical element relative to a second glass-based optical element, applying a glass-based bonding compound about the first and second optical elements, and applying sufficient localized heat to the glass-based bonding compound to cause the glass-based bonding compound to soften and fuse with the optical elements.

Abstract: A screw type dewatering machine according to the present invention includes inner and outer sleeves (1, 2), an annular space chamber (3) defined therebetween, a coil-like screw (4) rotatably disposed in the annular space chamber (3), and drain screens (5, 12) disposed on the inner sleeve (1) and/or the outer sleeve (2), and is characterized in thata support ring (16) is attached to the outer periphery of one end of the coil-like screw (4) and is rotatably supported by the outer sleeve (2).

Abstract: A method for zero correction in torque sensors, such as magnetostrictive torque sensor and strain gauge type torque sensor. Torque measurement is initiated when absolute values of torque signals are greater than a first set value, sampling measurement is carried out at predetermined intervals after the initiation. After absolute values of the measured torque signal values become lower than a second set value, an average value for a predetermined number of torque signal values whose absolute values are lower than a third set value is set as a new zero. The method permits proper measurement and correction of zero signals from torque sensors employed succesively at locations subject to impulse-like action of a torque load.

Abstract: A system for generating, editing, executing, monitoring and debugging an application program for controlling an industrial automation mechanism comprising components of logic, motion and/or process control. The programming and operating environments contain a single Man Machine Interface (MMI) with close and intuitive linkages between sequential programs and continuous programs that aid in the programming, operation and troubleshooting of application programs.

Abstract: The invention relates to a ball valve of the trunnion type, comprising a valve housing having an oppositely directed coaxially aligned inlet and outlet, each of which being provided with an internal seat, and a reversible conventional valve ball formed with a through-going passage in the form of a central bore, adapted to be brought substantially into alignment with said inlet and outlet in the open position of the valve, and wherein the valve ball is adapted to close the passage through the valve housing in the closed position of the valve, establishing a sealing effect at the seats of the valve housing, the sealing surfaces of said seats following an eccentric course in relation to the geometric center of the valve ball.
