Abstract: A system and method for monitoring the operating parameters of an electric arc furnace having a primary electrical circuit comprising a primary current transformer. The method includes monitoring the furnace's primary current transformer; collecting data therefrom; transmitting the collected data to a server having an operatively connected monitor; and displaying the collected data on the monitor in substantially real-time. The server also collects information about the performance of the furnace from a programmable logic computer and information entered manually by an operator at a furnace monitoring viewer system, which may also be displayed in substantially real-time on the monitor.

Abstract: Protective eyewear for protecting a wearer's eyes during a sporting event. The protective eyewear comprises a frame and a metal protective section. The frame includes a top support, a pair of armatures, and a grooved opening traversing the top support and each armature. The metal protective section includes a perimeter and an extension attached to the perimeter and shape to be removably engaged to the grooved opening in the frame. Additionally, the metal protective section includes a plurality of substantially aligned elongated bars horizontally segmenting the metal protective section. A plurality of cross members is vertically positioned to connect the elongated bars of the metal protective section and protect the eyes of the wearer.
Abstract: In a method for optimizing a cutting process in milling machines which are used to machine road coverings, which comprise a milling device fitted with milling tools which is sprayed with liquid in order to cool the milling tools, in addition to a drive motor, the following steps are provided: detection of the at least one parameter which is representative of the instantaneous power output of the milling device and controlling the amount of cooling liquid supplied according to the at least one parameter which is representative of the instantaneous power output of the milling device.
Abstract: A storage building for the storage of corrosive materials. The storage building comprises a floor, a plurality of columns extending from the floor, a plurality of crossbeams with each beam connecting at least two of the columns, a plurality of substantially vertically oriented supports extending from the crossbeams, a plurality of rafters attached to the supports and at least one roof panel spanning between two of the rafters.
Abstract: The invention relates to a self-propelled civil engineering machine, in particular a road-milling machine, a road recycler, or a road stabilizer, having a frame carried by a set of running gear, a working unit for performing work required for the civil engineering operation, and in particular a working drum, and a drive unit carried by the frame of the machine, to drive the working drum. A power transmitter is used to transmit the driving power from the drive unit to the working unit. The drive unit of the self-propelled civil engineering machine has a first and a second drive engine, the power transmitter being so designed that the driving powers coming from the first and the second drive engines can be transmitted to the working unit together.

Abstract: A switch useful for, inter alia, a touch type keyboard or keypad which may be used for a personal computer or the like in a substantially waterproof form while being relatively inexpensive to manufacture.
Abstract: A bar connecting apparatus applies clips to connect transverse bars used in reinforced concrete. A clip string is fed into the bar connecting apparatus by a clip feed assembly, so several pairs of transverse bars can be connected in rapid succession. A hammer reciprocates in the barrel of the bar connecting apparatus, and drives a clip from the barrel into engagement with the bars. An alignment head aligns the bar connecting apparatus with the transverse bars so the clips properly engage the bars.
Abstract: An over-molded runner for a lacrosse pocket comprising a substrate portion and an over-molded portion or optionally a completely molded runner providing for improved pocket characteristics.
Abstract: A bat having a handle portion, a transition portion attached to the handle portion, and a barrel portion attached to the transition portion. The area(s) adjacent to the central portion of the barrel have an increased performance with respect to the central portion of the barrel to effectively enlarge the sweet spot, or preferred hitting area. At least one tubular member of the barrel is circumferential aligned and axially spaced from another tubular member.
