Abstract: A percussion tool such as a hammer head comprises a housing for receiving a tool. A rotary drive mechanism rotates the tool about a longitudinal axis. A strike bolt is arranged for impacting against the tool. A cylinder sleeve is mounted coaxially with the longitudinal axis. A piston is slidable within the sleeve and is arranged to impact against the strike bolt. An impact drive mechanism is provided for imparting sliding movement to the piston toward the strike bolt. The impact drive mechanism comprises a wobble drive member mounted for longitudinal reciprocal movement and for rotary movement about an inclined axis disposed at an acute angle relative to the longitudinal axis. The wobble drive member is operably connected to the cylinder sleeve and to the rotary drive means to be driven thereby about the inclined axis so as to be longitudinally reciprocated. Thus, the rotary forces and impacting forces are derived from the same source.

Abstract: For driving unipolarly operated windings of an electronically commutated dc motor, each of the windings has a final power stage allocated to it. The final power stages are driven selectively and in cyclical sequence via an analog multiplexer dependent on rotor position signals. A drive of the final power stages is defined via a control voltage supplied to a common input of the analog multiplexer. The final power stages are referenced to ground via a common intermediate resistor. A comparator having first and second inputs is provided. A current corresponding to a rated value of the motor current and defined by external drive signals is impressed on a control resistor connecting to the second input. The intermediate resistor connects to the first input. At the control resistor and at the intermediate resistor voltages are developed which correspond to the rated value and actual value respectively of the motor current and which are compared in the comparator. An output of the comparator is connected to the common input of the analog multiplexer.

Abstract: Images of successive portions of a surface of a strip are formed and converted as analog signals. Signals typical of each image are stored in an image storage whereas the analog signals relating to each image are converted in numerical form by splitting up the image into image elements. Each of the image elements is given a numerical value, and then filtered, in order to sense the relative variations of the numerical values of the image elements. To determine whether or not to deliver a defect-sensing signal in terms of the sensed variations, the filtered signal is scanned. The typical image is stored in response to the transmission of the defect signal. Every read-in information is stored and displayed at a check station long enough for a visual check of the image it represents.

Abstract: The invention relates to an arrangement for transporting disintegrated solid particles, in which the particles (18) are transported by means of a quantity of air placed under an overpressure (14). The weight ratio of the particle/air mixture lies within the range at which particle transportation (11) gives rise to migrating particle agglomerations. Transportation of the particles is terminated in a particle agglomeration equalizing means (7,10), from where the particles are transported further in the form of a particle.'air mixture equalized in time.Particle transportation is effected by at least two stages, a first stage (11) in which the weight ratio of the particle/air mixture is greater than fifteen, and a second stage (6) in which the weight ratio of the particle air concentration is greater than five and lower than the weight ratio of the particle/air mixture in the second stage.The arrangement can be used as a means for transporting powdered coal to a powdered-coal burner (1) connected to a combustion furnace (2), in which arrangement powdered coal is transported through conduits (11,6) by a quantity of air placed under an overpressure.

Title: Process and installation for preparing binder-free hot-briquets
Inventor: KAAS WERNER
IPC: C22B1/248
Filed: 1986-07-01
Granted: 1989-10-26
Abstract: The present invention relates to a process and apparatus for preparing binder-free hot briquettes for smelting purposes consisting of iron-containing pyrophorous finely divided solids. Before briquetting, the finely divided solids are blown-through by means of a rising oxidating heated gas flow and held in a fluidized bed. During said process the gas flow is controlled in such a way that by oxidation of at least part of the metallic iron the temperature of the finely divided solids is increased to about 450 DEG  to 650 DEG C. Subsequently, the solids are briquetted in hot condition. Characteristic for the invention is that there is added to the fluidized bed sensible heat from the outside until oxidation of part of the metallic iron starts, and that the fluidization bed is submitted to the effect of vibrations favoring the conveying of the solids over the fluidized bed.

Abstract: In an automatic aspirator-transfer valve controlling the delivery of washing fluid from a supply (M) to a cleaning gun (B) and having a valving piston (2) movable between a first or rinsing position, in which it opens bypass conduits (15) bypassing an injector (3,21,4) and a second or washing position in which it closes said bypass conduit (15) and enables the injector (3,21,4) to aspirate washing fluid from a reservoir (not shown) through a non-return valve (11), a side inlet (5) and a conduit (22) to its side inlet (21), the novel aspect is that the side inlet conduit (22) is separated from the space within the housing bore (20), in which the valving piston (2) can slide. 
<??>In this manner it is avoided that a portion of the washing agent may fill the space within the housing bore (20) and leave the valve in the form of a "plug" when changing from the washing mode (Bottom Figure) to the rinsing mode , thus avoiding both the issuing of dangerously high concentrations and unnecessary waste of washing agent.

Abstract: A method and device for determining the presence of an analyte in a sample suspected of containing the analyte is disclosed. The method involves contacting a test solution containing the sample and a first member of a specific binding pair with an end portion of a strip of bibulous material capable of being traversed by the test solution through capillary action. The first member of a specific binding pair is capable of binding the analyte. The strip contains a second member of a specific binding pair integral therewith for concentrating and non-diffusively binding the first sbp member at a small situs on the strip separated from the end portion of the strip. The detectible signal is produced in relation to the presence of the analyte in the test solution. The test solution passes through the situs as the test solution traverses the bibulous material. After the test solution has been allowed to traverse at least a portion of the strip, the strip is contacted with a developer solution containing members of a signal producing system in a manner that provides contact of the developer solution with the small situs following its contact with the test solution. The strip is then contacted with any remaining members of the signal producing system. The detectible signal produced at the situs is then compared with the signal detectible at a portion of the strip other than the situs to determine the analyte in the sample. In one embodiment of the invention the signal produced at the small situs has a sharp-edged distinctive pattern that provides a sharp contrast to the signal produced at adjacent sites on the strip when analyte is present in the test solution.

Abstract: An apparatus and method are disclosed for improving the recognition of reference data in a laser writing process, by storing the locations of chip topography situated along the scan raster in a memory. Using an entry code (reference mark) to provide synchronization of the laser beam and the chip topography, the digital signal coming from the detector of the scanning laser beam is checked for accuracy against the stored pattern. A synchronous correlator circuit is used to provide a corrected output based on the stored information and the actual detected signal which is then used to control the operation of the laser pattern generator. Incorrect tracking of the laser pattern generator due to defects in the scanned surface can thus be reduced or eliminated. Due to this improved recognition of surface reference points, smaller geometries can be used.
