Abstract: In a method for operating a machine tool, a machine-specific flow resistance and a respective tool-specific flow resistance are ascertained for various tools. Tool-specific regulator parameters for regulating a pump of a coolant lubricant device are computed on the basis of the machine-specific flow resistance and the tool-specific flow resistance of the tool chucked in a tool spindle. Subsequently, the machine tool is operated using the tool-specific regulator parameters. In this way, a rapid and exact feed of coolant lubricant to the machining point of the respective chucked tool is enabled in a simple and flexible manner.

Abstract: A housing of a device comprises a screw boss that extends outwardly from a first base plate proximate to a corner of the housing. Additionally, the housing of the device includes a force dissipation member. The force dissipation member includes a central portion that is sized to detachably attach around the screw boss. The force dissipation member further includes at least two arms that extend outwardly from the central portion, wherein each arm of the at least two arms is attached to a different side of the two walls of the housing.

Abstract: Example embodiments relate to LIDAR systems with multi-faceted mirrors. An example embodiment includes a LIDAR system. The system includes a multi-faceted mirror that includes a plurality of reflective facets, which rotates about a first rotational axis. The system also includes a light emitter configured to emit a light signal toward one or more regions of a scene. Further, the system includes a light detector configured to detect a reflected light signal. In addition, the system includes an optical window positioned between the multi-faceted mirror and the one or more regions of the scene such that light reflected from one or more of the reflective facets is transmitted through the optical window. The optical window is positioned such that the optical window is non-perpendicular to the direction toward which the light emitted along the optical axis is directed for all angles of the multi-faceted mirror.

Abstract: A ball valve includes a valve body and a valve assembly. The valve body includes an elongated, generally tubular portion and a hydroformed stem seat. The stem seat extends generally radially from the tubular portion. The tubular portion and the stem seat are unitary. The valve assembly is coupled to the body at the stem seat.

Abstract: A method is proposed for controlling tool change operations on a machine tool, wherein a machining procedure on a workpiece includes a sequence of machining operations having in each case a particular tool and in each case a particular duration, and for a tool change, tools of a tool spindle are provided by a second storage device in communication with a first storage device, and wherein there is associated with the machining procedure a sequence of tool provision operations in which a tool provision operation has in each case a particular duration, wherein the method includes a determination stage wherein the durations of the machining operations and the tool provision operations are determined, and a control stage wherein the tool provision operations are temporally grouped in relation to the machining operations such that the tool provision operations bring about a minimized idle time in the machining procedure.

Abstract: Methods and apparatus for improving the cold flow properties of diesel are described. The methods include hydrocracking a hydrocarbon feed to provide a reactor effluent comprising a product mixture comprising diesel, kerosene, and naphtha, and unconverted feed. The reactor effluent is separated in an enhanced hot separator into an overhead vapor stream comprising the product mixture and a liquid bottoms stream comprising the unconverted feed. The overhead vapor stream is contacted with a dewaxing catalyst in a finishing reaction zone to convert a portion of n-paraffins in the product mixture to iso-paraffins. The effluent from the finishing reaction zone is separated in a high pressure separator into an overhead stream comprising gases and a liquid stream comprising the product mixture. The liquid stream from the high pressure separator is separated into at least a diesel stream in a fractionation zone.

Abstract: A method is provided for testing the fit or for testing the imbalance of a tool exchangeably accommodated in a tool spindle which is mounted for rotation about a central longitudinal axis and is rotationally driven by a spindle drive motor, including: inserting the tool on the tool spindle; making the tool spindle rotate with a specific rotational frequency fdef about the central longitudinal axis by means of the spindle drive motor; analyzing an actual value of a controlled drive current of the spindle drive motor with respect to a frequency component with the rotational frequency fdef; and determining whether the frequency component with the rotational frequency fdef lies within a threshold value range.

Abstract: Footwear with an embedded tracking device includes a sole and an upper. The tracking device is disposed in a cavity formed in the top surface of the sole. A wireless communication antenna and/or a location signal antenna is disposed on the upper. The antenna(s) is/are connected to the tracking device via a flexible circuit substrate. In a particular embodiment, the location signal antenna is a passive, directional GPS antenna supported in an upwardly facing position in the heel portion of the upper. A method for manufacturing footwear with an embedded tracking device is also disclosed. The method includes providing a footwear upper, incorporating an antenna in the footwear upper, providing a footwear sole, fixing the footwear upper to the footwear sole, incorporating a tracking device into the footwear sole, and connecting the tracking device to the antenna.

Abstract: An improved breathing devise, for use in the nasal passageways. This nasal breathing apparatus utilizes a flexible tube, that defines two centrally adjacent notches, spaced apart by a central tube portion. The terminating ends of the tube preferably have a portion of the circumferential tube removed, so that the ends define curved flanges. The section of modified tubing is bent approximately 90 degrees from the central portion, with the arcual outer surfaces of the tube ends being placed directly into the nasal passageways. The flexible tube will urge the nasal passageway walls apart, thereby increasing the overall diameter of said passageways. Airflow is not significantly restricted, due to the tubular configuration of the apparatus, which conforms to the nasal passageway shape it contacts. The central tube portion is capable of receiving an aromatic plug, which releases chemical substances adjacent to the nasal openings.

Abstract: The rotary engine is an expansion fluid turbine for supplying power to lawn mowers, small vehicles, electrical generators, and the like. Fuel and oxygen are supplied from bladder tanks to combustion chamber, while water is supplied to an annular sleeve surrounding the combustion chamber in a mist by a spray nozzle. Ignition of the fuel-oxygen mixture by a glow plug heats the mist to supply steam for turning a rotor. The rotor has a circular top plate with a plurality of pin diffusers depending from its lower surface, and an annular bottom plate with a plurality of pin diffusers attached to its upper surface. A swirl pan has a flange on which the lower plate seats, and defines a swirl chamber. The steam enters the swirl chamber through a bifurcated intake conduit. Swirling in one direction causes rotation, while swirling in the opposite direction causes braking.
