Abstract: The invention relates to a method for producing a separation net and to a separation net (10), in particular for vehicle interiors, which has a net-like, tear-resistant textile web (11) formed of textile threads (12), which is cut to any peripheral contour, wherein the loose ends (13) of the textile threads (12) that were created by a separating cut are securely bound at the edges in a plastic material of a single-layered edge strip (18). The textile web (11) can have any peripheral contour, and the loose ends (13) of the textile threads (12) of the textile web (11) that were created by a cutting to size are embedded at least at the side edges (16, 17).

Abstract: An insert element (8) for sealing cavities (6, 7) in vehicle body carriers (4) has sealing means constituted by a foamable material (11) which is secured in the cavities (6, 7) by securing means (9). The insert element (8) comprises a foamable material (11) and a support structure (10) which comprises a frame (13) and an inner part (14) for carrying the foamable material (11). The frame (13) has at least two lateral and not immediately oppositely arranged support faces (12), and carries securing means (9). With this arrangement, the foamable material can completely engulf the securing means (9) with foam during the foaming process and can flow into apertures of an intermediate metal sheet (5) foreseen for receiving the securing means (9). This ensures that these apertures are impermeably sealed against air and noise during the foaming process.

Abstract: A film winding spool for a photographic camera has an inner cylindrical member driven in rotation and provided with engaging formations for engaging an initial portion of the film, and an outer cylindrical member surrounding the inner member so as to form a space therebetween and having a slot for introducing the initial portion of a film into this space and an outer surface for winding successive coils of the film, wherein the outer member has at least one opening arranged so that a piece of the film separated from a remaining part of the film can be withdrawn from the space between the inner and outer members through the opening.

Abstract: A fuel injection system is proposed which serves to provide the most precise possible adaptation of the fuel-air mixture to operating conditions of the internal combustion engine. The fuel injection system includes metering valves, each of which is assigned one regulating valve, whose movable valve element can be exposed on the one hand to the fuel pressure downstream of the respective metering valve and on the other hand to the pressure in a control pressure line, which is limited on the one hand by an electro-fluid converter of the nozzle/bounce plate type and on the other hand by a control throttle. The electro-fluid converter is triggerable in accordance with operating characteristics of the engine.

Abstract: A differential pressure valve is proposed for a fuel injection system of an internal combustion engine. The differential pressure valve includes a diaphragm embodied as the movable valve element, which separates two chambers from one another. A fuel supply line discharges into one chamber and a valve seat carrier provided with a valve opening protrudes into this chamber. This chamber also houses a filter element and a valve spring is disposed coaxially with the valve seat carrier between upper and lower spring plates. The filter element is disposed such that a subsequent change in the tension of the valve spring is also possible. To this end, the filter element can engage the upper spring plate on one side in a sealing manner and on the other side can be supported in a sealing manner in a groove of the wall of the chamber (FIG. 1). In order to assure the free mobility of the filter element, it is provided with an elastically deformable area. As shown in FIG.

Abstract: A fuel injection system is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine. The fuel injection system includes an air flow rate member, which actuates a metering and distribution valve. A reservoir is disposed in a pressure control line which branches off from a fuel supply line, by means of which reservoir a flushing valve can be affected in such a manner that below a certain fuel pressure in the pressure control line the flushing valve is opened, as a result of which the fuel supplied to the individual injection valves can flow back through outflow lines to the fuel tank and thus closes the flushing valve above the certain fuel pressure. Above the certain fuel pressure, the electrical circuit of the starter motor is simultaneously closed. Thus, upon starting the engine, all the lines and units of the fuel injection system are filled with fuel, so that a secure start is assured.

Abstract: A metering and distribution valve assembly is proposed for a fuel injection system of an internal combustion engine. The metering and distribution valve assembly includes a control slide having a head 68 and a control edge and a slotted sleeve with at least two control slits. The control edge opens the control slits to a greater or lesser degree in accordance with the relative motion between the control slide and the control slits in the slotted sleeve. An end face of the control slide adjacent to the control edge is exposed to a control pressure which is lower than the system pressure engaging the control edge. The pressure drop at the circumference of the control slide head formed between the control edge and the end face is capable of being influenced in such a manner that the control slide head rests unilaterally on the slotted sleeve at least during a portion of the displacement movement. As a result, better metering precision is obtained.

Abstract: The control mechanism for a photographic camera using film carrtridges having coded marks indicative of the sensitivity of the employed film includes a hand-operated control member for setting at least one exposure parameter, an axially movable objective for setting the distance, an adjustable diaphragm, a scanner movable against the marks on the cartridge for displacing the control member in response to the coded marks, a stationary cam surface engaging the objective, transmission gears coupled between the control member and the objective to axially displace the latter according to a distance setting and according to the shape of the stationary cam and curves provided on the control member to display at least the applicable exposure range and the flash distance limits for the employed film sensitivity.

Abstract: A fuel supply device is proposed which serves to supply fuel to a mixture-compressing, externally ignited internal combustion engine with a good distribution of the fuel-air mixture. The fuel supply device includes a fuel metering device activated by an air metering device arranged in the air intake manifold of the internal combustion engine with the fuel metering device being connected to an air line in which the metered fuel is mixed with air before the injection into the air intake manifold. Between the air line and the fuel line, upstream from the fuel metering position, a filter having a fine-meshed weave is arranged by means of which the fuel is prevented from flowing out over the air line in an undesirable manner.

Abstract: A fuel supply device, which serves to predetermine a fuel quantity that is proportional to the aspirated air quantity, and also serves to spread the air-fuel mixture. The fuel supply device includes an air metering device, which is arranged in the air intake manifold of the internal combustion engine and activates a fuel metering device, which has a control slit that opens a control groove by a varying amount. The control slit and the control groove are rotatable relative to each other, and the control groove has at least one control edge, which overlaps the control slit and is formed at an angle relative to the axis of rotation. The control slit is arranged in a guide sleeve and the control groove is arranged in a rotatable sleeve mounted in the guide sleeve with the rotatable sleeve being arbitrarily shifted relative to the guide sleeve.
