Abstract: The invention relates to a hand-held tool, in particular a rotary hammer, a percussion hammer, or a sabre saw. The hand-held tool is equipped with a drive unit and a stroke-generating element; the drive unit is embodied to move the stroke-generating element in a reciprocating fashion along a translation axis. The hand-held tool has at least one counterweight; the counterweight is operatively connected to the drive unit in such a way that it is possible to at least partially compensate for forces at least indirectly caused by the reciprocating motion. According to the invention, the counterweight in the hand-held tool is supported so that it is able to move, in particular to reciprocate, coaxial or parallel to the translation axis.

Abstract: Method and system to configure a common set of electronic components using software in order to simulate different electronic, mechanical and/or electro-mechanical instruments or instrument functions. For each instrument function or traditional mode of operation to be simulated, software models are created which when directed to the electronic components, cause the electronic components to respond to input in the same manner that the actual, traditional physical instrument would respond to satisfy the same test requirement input. The software models are preferably stored in a model repository which is searchable to enable a user to select the instrument function or traditional mode of operation to be simulated with the corresponding model being provided to the electronic components. Once the model, i.e., a function for each synthetic element, is downloaded and the electronic components configured according to the model functions, testing of the assemblies or other UUTs can begin.

Abstract: A distributed test system for implementing enhanced BIT (Built-In-Test) within an ESM (Electronic Surveillance Monitoring) or RF receiver system. The distributed test system includes a system processor, a programmable RF source element or other comparable test signal generating arrangement, and switched path coupled elements and various measurement elements, each embedded at strategic locations within the ESM system so as to effect maximum path coverage and test benefit.

Abstract: Video selection display unit that is capable of routing real-time output signals having a video component from different video signal sources, e.g., different instruments or home entertainment devices, to a single output for display on a monitor or other type of video display. The video selection display unit may be part of an automatic test system or home entertainment system. Control of the video selection display unit can be effected locally via a user interface, such as one or more pushbuttons, and/or remotely over a network which may be the same network used for communication with the instruments or devices or using an infrared remote control unit.

Abstract: A system for developing sampling plans includes a coordinate measuring machine (CMM) that inspects features of objects. The system includes an input module that is used to input inspection criteria to generate a sampling plan for said CMM and that is used to selectively modify said inspection criteria to develop multiple sampling plans. The system includes a storage device that stores said inspection criteria and a control module that controls the CMM using said inspection criteria.

Abstract: A door security system utilizes a bar that spans the distance across a door and prevents the door from being opened. The bar combines an elastic, flexible hollow rod with a cable that is pliable but generally does not flex. The bar flexes when an individual attempts to force open the door against the bar. When the bar flexes it generates a force that acts to close the door.

Abstract: A tool holder for a power tool, such as a drill hammer, a chisel hammer, and both, includes a striking mechanism for strikingly driving a tool, a base body, a drive part on which the base body is releasably mounted, at least one locking body for releasably mounting the base body on the drive part, a component having a throughgoing passage in which the at least one locking body is arranged, a securing body which radially fixes the at least one locking body in its engaging position, an actuating element for unlocking the securing body from its locking position to an unlocking position for radially reieasing the at least one locking body, and at least one holding element which holds the at least one locking body in the unlocking position of the securing body in the throughgoing passage. The holding element is lowered or lowerable into the component having the throughgoing passage and is overrun by the securing body.

Abstract: Method for the treatment of fluidized carbon black with gases in a fluidized bed, wherein the carbon black and the treatment gases are conveyed for introduction in an unique operating procedure into the treating region in a countercurrent stream manner. The mass streams of the carbon black and the treating gases are held constant and the mass streams of the starting carbon black or the treated carbon black is regulated with the help of an optical electrical level sensor so that the height of the fluidized bed is held on a predetermined level. An apparatus is shown for the carrying out of the fluidized bed countercurrent process which has a novel carbon black product delivery system and is provided with a optical electrical level sensor means for controlling the level of the fluidized bed. The sensor comprises a hair pin shaped lighting circuit composed of two legs or rods separated by a gap.

Abstract: A method for the consumption dependent complete vaporization of liquid nitrogen oxide is shown where the liquid nitrogen oxide under pressure is passed through a buffer tank and is charged into a falling film evaporator. The unevaporated residual amount of nitrogen oxide is then subjected to heat in an after evaporator in order to completely vaporize the nitrogen oxide. The combined streams are then led out of the falling film evaporator and after evaporator through at least one safety trap to the ultimate take-off points. This results in the charge of the liquid material to the falling film evaporator being controlled through the pressure in the conduit system between the falling film evaporator and the points of utilization and permits a constant, previously determined pressure to be maintained in the system independently of the amount of material withdrawn.
