Abstract:
The invention relates to a computer-implemented method of trading securities, a computer-readable medium carrying one or more sequences of instructions for trading securities, and a computer program product for use with a graphics display device. The program determines a reference price for the security, monitors the value of the security over time, and receives an input corresponding to a differential in the value of the security. A trigger price is determined for the security as a function of the differential and the reference price. The program liquidates the security after determining that the value of the security reaches or passes the trigger price in a first direction. After liquidating the security, the program automatically acquires at least one position in the security when the value of the security reaches or passes the trigger price in a second direction opposite to the first direction.
Abstract:
A portable handheld work apparatus such as a sweeper, motorized cultivator or the like has a drive motor (3), a work tool, which is driven by the drive motor (3), and at least one transport wheel (13). The transport wheel (13) is fixed to the work apparatus via at least two struts (14, 15). A first strut (14) is rotatably mounted on the work apparatus at the end (19) of the strut facing away from the transport wheel (13) and a second strut (15) can be fixed with its end (20) to at least two attachment points (17, 18) on the work apparatus with the end (20) facing away from the transport wheel (13).
Abstract:
In a fuel cell system having a fuel cell and a catalytic burner connected downstream thereof, an additional hydrogen-containing medium is fed to the catalytic burner.
Abstract:
The invention is directed to a cutterhead for a portable handheld brushcutter for cutting grass, weeds and the like. The cutterhead includes a housing which holds a spool for the cutting filament. Two spool chambers are formed on the periphery of the spool by a radial partition wall. A cutting filament is wound in each of the spool chambers and each of the cutting filaments is assigned an exit opening in the housing which extends into free space. The partition wall lies at the same axial elevation with the exit openings. The partition wall is provided with at least one lead-in channel through which the filament is guided into the interior of the spool when inserted. A reliable introduction of the filament is provided by a simple configuration of the cutterhead and makes a reliable wind-up and pay-out of the filament possible. This is achieved by providing a lead-in channel for each spool chamber with the entrance of the lead-in channel being defined by an insert funnel. The insert funnel is provided on each of the sides of the partition wall with a filament guide. Each side faces toward the assigned spool chamber. Furthermore, the lead-in channel extends non-linearly in the spool.
Abstract:
A floor module for a motor vehicle includes a floor shell, which can be fastened to a shell of the motor vehicle, and equipment with a plurality of variant-specific constructional units arranged on the floor shell. A method for assembling a floor module involves equipping a respective shell of the motor vehicle with a floor module with corresponding chassis and drive train.
Abstract:
A portable spraying device has an internal combustion engine and a blower driven by the internal combustion engine. A blower tube is connected to the blower and conveys a blowing air stream generated in the blower. A spraying agent reservoir is provided and a spraying agent line is connect to the reservoir and conveys a spraying agent stream from the reservoir into the blowing air stream. A control valve is arranged in the spraying agent line. A throttle control acts on the internal combustion engine for controlling an engine output. A stop switch acts on the internal combustion engine for interrupting ignition. An actuating element acts on the control valve for actuating the control valve to control the spraying agent stream. A handle with a handle head is provided and the throttle control, the stop switch, and the actuating element are arranged in the handle head.
Abstract:
A fuel cell system, which may include a fuel processing subsystem for converting hydrocarbons into a hydrogen-rich gas, is designed so that at least some of the components of the fuel cell system are contained inside at least one housing. The housing contains a recombiner to convert hydrogen and oxygen into water. The housing may also contain a temperature sensor in the vicinity of the recombiner.
Abstract:
The invention relates to an eccentric drive (1) and especially to an eccentric drive for a portable handheld work apparatus having a wheel (3) driven by a drive motor (2). A cam (5) is eccentrically fixed to an end face (4) of the wheel (3). The cam (5) is held by a connecting rod (6) and cylinder-shaped roller bodies (7) are mounted between the connecting rod (6) and the cam (5). The roller bodies (7) have axial ends (8) which engage in an annular slot (9) of the wheel (3). A holding element (11) is disposed on the cam (5) and limits the axial play of the roller bodies (7).
Abstract:
The invention relates to a two-cycle engine for a drive engine in a portable, manually operated tool. The combustion chamber formed in a cylinder is delimited by a piston that moves up and down, whereby the piston, by means of a connecting rod, drives a crankshaft rotatably mounted in a crankcase. The combustion chamber has an outlet for removing waste gases, and provided for supplying a fuel/air mixture prepared by a mixture preparation device, and combustion air, are gas-supplying channels that open into the combustion chamber. In order to reduce scavenging losses, it is provided that for the entire duration of the gas exchange exclusively air flows in the area near the outlet and exclusively fuel/air mixture flows out of the crankcase in the area further away from the outlet.
