Abstract: A tubular bag machine has between a filling tube and a shaping tube at least two sealing elements, which divide an annular space, formed by the filling tube and shaping tube, into a feed channel and a suction-removal channel. The two channels are connected to a suction device with a filter by connecting lines. The design and arrangement of the sealing elements produce a closed circuit for the air or inert gas used for dust removal.

The net support has two diverging arms connected together at their outer ends by a first flexible element. The bag net is carried by the net support around an open mouth of said bag net. The handle is tubular and the divergent arms of the net support are movable lengthwise of the handle to a retracted position substantially parallel to the axis of the handle with the net being accommodated inside the handle.

Abstract: An apparatus for transporting containers intermittently. The apparatus has two guide rails which extend in a horizontal plane. Container carriers, which have receiving elements for the containers are disposed on the guide rails. The container carriers are fed by means of gearing embodied on them and transport gears embodied on the guide rails. Transfer devices and format changer devices are disposed on the ends of the guide rails. The output of the apparatus can be increased by subdividing it into continuous and intermittent feed zones.

Abstract: The invention relates to a spring-loaded nonreturn valve. For ease of production and assembly, a spring element is designed as a leaf spring which is bent in a zigzag shape and is arranged in a transverse groove of a valve closure body. For connection to a spring holder, the leaf spring has a loop with which it is snapped in on a section of the spring holder bent out of wire. The spring holder has a spring ring which is integral with it and is inserted in a groove in a blind bore of a delivery piston, forming a valve housing, of a reciprocating pump.

Abstract: An electromagnetically operable valve having a fuel inlet connecting piece which is surrounded by a magnet coil and is used as a core, at least a part of the valve is surrounded by a plastic sheath on which an electrical connecting plug is integrally formed. In the novel valve, the electrical connecting plug is injection moulded at the same time as the extrusion coating of the magnet coil and thus forms an independent plastic injection moulding. Only one valve extrusion coating tool is now required for different embodiments of the electrical connecting plug, resulting in greater flexibility in the assembly line. The valve is used as an injection valve for fuel injection systems.

Abstract: A distributor fuel injection pump for internal combustion engines having at least one pump piston, which is guided in a cylinder bore and defines a pump work chamber therein and whose axial feed stroke motion is produced by a cam drive having at least one roller running on an annular cam race; at least one part of the cam drive is rotated to adjust the supply onset of the pump piston. This adjusting device is integrated into the housing which contains the cam drive by providing that the adjustable cam ring has radially protruding pressure vanes, each of which protrudes into a pressure chamber in the pump housing and divides this chamber into two pressure subchambers. Rotating the cam ring for the purpose of adjusting the supply onset of the pump piston over a wide angular range can now be effected by imposing pressure in alternation upon these pressure subchambers, which act in opposition upon the pressure vanes or the cam ring.

Abstract: A pile bearing capacity determination system which allows the pile driver operator to determine the bearing capacity of a pile while it is being driven without interrupting the driving operation to perform a dead load test. Force sensors are cast in the pile at the head, toe and mid-portion and also an acceleration sensor is cast in the head of the pile. An ultra-fast sensor produces a detailed profile of the force exerted by each hammer blow on the pile. The hammer force at which the pile breaks loose from surrounding soil and begins to move during a hammer blow correlates quite well with bearing capacity of the pile determined by dead load tests. Points on the acceleration curve help verify transition points on the force profile. The force and acceleration curves are indicated simultaneously on an oscilloscope and plotter.

Abstract: A fuel injection system for internal combustion engines having a high-pressure fuel pump, which supplies fuel from a low pressure chamber via a supply line into at least one high-pressure accumulation chamber. The at least one high-pressure accumulation chamber communicates via high-pressure lines with injection valves, which protrude into the combustion chamber of the engine to be supplied and whose opening and closing movements are each controlled by an electrically triggered control valve disposed in the high-pressure line at the injection valve. In order to prevent an uncontrolled escape of fuel in the event of a breach of a high-pressure line, flow limiting valves are additionally provided in all high-pressure lines, which valves close these lines when an admissible throughput quantity is exceeded.

Abstract: A valve for the introduction of fuel or a fuel/air mixture in a combustion space of an internal combustion space of an internal combustion engine which works with charge stratification in the combustion space, and with spark ignition of the introduced fuel or fuel/air mixture by a spark plug. To ensure the ignition of the fuel/air mixture contained in the combustion space, there is branched off from an umbrella-like injection jet formed by the fuel or fuel/air mixture an ignition jet which, deviating from the umbrella-like or cone like configuration of the injection jet, comes into the region of the spark plug, in order thus to provide a fuel-rich fuel/air mixture in the region of a flashing over of the ignition spark of the spark plug. This takes place by means of a guide face of the valve, in which the guide face is interrupted by a recess.

Abstract: A package for spark plugs including a packaging material blank which is folded to form two hollow wall portions which receive opposite ends of the spark plugs. An intermediate section which is intregally connected to the hollow wall portions and a tab if formed onto one of the hollow wall portions, so that the same side of the package material blank always points outwards. A cover or a sleeve is arranged to cover the follow wall portions and the intermediate section as protection against theft. Viewing windows, and tear tabs which are bounded by perforations permit the spark plugs to be checked and removed easily.

Abstract: For reliable, secure contacting of a fuel injection valve, the valve has a guide bolt, which with its free end protrudes past free ends of the plug elements, so that prior to the insertion of the plug elements into corresponding receptacles, this guide bolt slides in a guide opening, so as to center the plug elements of the fuel injection valves. The invention is intended for contacting electromagnetically actuatable fuel injection valves for fuel injection devices.

Abstract: The invention relates to a fuel injection pump for internal combustion engines with a pump plunger (18), a drive shaft (11) for the actuation of the pump plunger (18) and a rotational-angle sensor (30) for detecting the angular position of the drive shaft (11), the pulse generator of which is designed as a generator wheel (32) seated firmly in terms of rotation on the drive shaft (11) and the pulse pick-up (31) of which is held on a carrier ring (35) seated rotatably on the drive shaft (11). For the purpose of narrowly toleranced exact association of the pulse generator wheel (32) and the pulse pick-up (31) both in the radial and in the axial direction, the pulse pick-up (31) is accommodated in a sensor housing (40) and this housing is fixed positively and frictionally on the carrier ring (35) by means of plug-in elements.

Abstract: A throttle-valve housing of plastic has a metal insert which achieves dimensional stability in the region of the throttle valve. The throttle-valve housing is formed of plastic with a cavity bounded by an inner wall surface. In the wall there is arranged a metal insert which is covered on all sides by the plastic material and effects a stabilization of the plastic material, so that distorting, shrinking or the like is prevented and dimensional accuracy of the inner wall surface is ensured. The novel throttle-valve housing is simple to produce and has a high dimensional stability in spite of being formed from plastic material. The throttle-valve housing is suitable for internal-combustion engines of motor vehicles.
