Abstract: The invention relates to a device for adjusting a checking unit of a presser foot, used in a sewing or embroidery machine. A needle bar moves the presser foot towards a needle plate, using a spring which is connected in series. The checking unit intercepts the presser foot using a checking element of the unit, before contact is made with the work piece to be sewn and controls the movement of the presser foot until the latter touches the work piece. The checking element and the needle bar are both operated by a common drive and the bedding position of the checking element can be modified in relation to the needle plate.

Abstract: A grinder for comminuting waste material comprises a frame structure (18, 20). A grinding rotor (24) is rotatably carried by the frame structure (18, 20.) The grinding rotor (24) carries a plurality of cutting tools (36) cooperating with a counter blade (26, 28) carried by the frame structure (18, 20). Two plate chain conveyors (68, 70) are vertically aligned so that working runs (80, 120) thereof form a converging moving wall funnel positively feeding pieces (146, 148) of material to be comminuted towards a grinding unit (12) formed by the grinding rotor (24) and the counter blade (26, 28).

Abstract: In order to regenerate the heat exchanger material located in the various segments of a housing section (2) of a regenerative post-combustion device (1), fresh air is fed via the flushing air connection (11) into the combustion chamber (8) of this post-combustion device (1), is heated there by a burner (9), and is fed to the rotary distributor (5) via a segment of the heat exchanger material. Heated air which, when passing through the heat exchanger material has picked up contaminants deposited thereon is fed to the inlet or outlet connection (4, 10) of the post-combustion device (1) via the rotary distributor (5) and, from there, is introduced once again into the combustion chamber (8). The rotary distributor (5) of the thermal post-combustion device (1) stops during this process which is continued until the heat exchanger material is heated to a temperature at which the contaminants absorbed by the heat exchanger material are released and combusted in the combustion chamber (8).

Abstract: A bath tap fitting is composed in the known way of a securing device which can be attached to a mounting plate and a movable outlet spout fitted to this. The securing device comprises a securing body which is composed of a lower part and an upper part which can be pushed onto the lower part so that it cannot turn but can be adjusted for height. An adjusting bush is axially fitted in the upper part of the securing body, which however can be turned. It has in the lower area an outer thread, with which it is screwed into a threaded hole of the lower part of the securing body. By turning the adjusting bush therefore the height of the upper part can be changed in comparison to the lower part. The upper part grips over the lower part with a skirt which is divided into segments from below by axis-parallel slits and has an outer thread there.

Abstract: An optical element (1) of an optical system has at least one chamber (5) that is sealed against atmospheric pressure and is enclosed by boundary surfaces and that has a fluid filling. At least one of the boundary surfaces of the chamber (5) is exposed at least partially to illumination light. It is configured so that a change in the fluid pressure inside the chamber (5) results in a change in non-rotational-symmetric imaging properties of the optical element (1) having n-fold symmetry. For this purpose, a fluid source has a fluid connection to the chamber via a fluid supply line (17). Furthermore, a control device is provided for the pressure in the fluid filling.

The system includes an intermediate bus; a bridge module that is coupled between the PCI bus and the intermediate bus. The bridge module includes a PCI interface and an intermediate bus interface and an IDMA channel coupled between the PCI interface and the intermediate bus interface. A control module is coupled between the bridge module and the DSP circuit, said control module having an intermediate bus control circuit and a DSP control circuit having a slave port controller coupled to the slave port (HPI) of the DSP and a master port controller coupled to the master port (EMIF) of the DSP circuit, whereby the master port continues to transfer data from the DSP circuit to the PCI bus when an additional master circuit is asserted on the PCI bus. The system provides a direct connect solution that also provides arbitration for multiple DSPs.

Abstract: The invention relates to a power & free conveyor which comprises a free rail (3) and a power chain (1) that follows said free rail (3), to a large extent, in a parallel manner. A transport carriage (4) provided with a front runner (5) and a rear runner (6) are arranged on the free rail (3). The front runner (5) and the rear runner (6) each comprise a carrier (11, 14) that can pivot between two positions. In an area of the movement path of the transport carriage (4), the course of the power chain (1) deviates from that of the free rail (3) so that the transport carriages (4) can no longer be moved via the front runner carrier (1) thereof. Instead, the transport carriage is pushed by the interaction between a chain carrier (2) and the rear runner carrier (14) that is swung out into a carrying position. The rear runner carrier (14) comprises two stabile positions which can be changed by overcoming a resistance.

Abstract: A projection exposure device, in particular for micro-lithography, serves to produce an image of an object in an image plane positioned in an object plane. This happens with the aid of a light source emitting projection light and illumination optics positioned in the ray path between the light source and the object plane. In addition projection optics positioned in the ray path between the object plane and the image plane serve to guide the projection light. A filter (7) is positioned in a filter plane which lies in the vicinity of a pupil plane between the light source and the object plane. This has a moveable filter element (22′) which has at least in certain areas (24) for the projection light a transmission factor which is greater than zero and less than 100%.

The system comprises a light source (30) as well as at least one optical element, in particular a lens or a mirror. In the region of at least one surface acted upon by the radiation (1) of the light source (30) the optical element is substantially symmetrical in relation to an axis of rotational symmetry (5). The optical element or its housing (6) is rotatably connected to a frame (7) by at least one bearing (8, 9, 10). An actuator (18) sets the optical element (25) or its housing (6) in rotation about the axis of rotational symmetry (5). The actuation cooperates with a control device (23). The latter activates the actuator (18) for rotation of the optical element at least temporarily during the period, when the optical element is exposed to lumination. In such a manner rotationally non-symmetrical image defects are compensated.

Abstract: An optical arrangement, in particular a microlithographic projection printing installation, has in particular a slot-shaped image field or rotationally non-symmetrical illumination. An optical element (1) is therefore acted upon in a rotationally non-symmetrical manner by the radiation of the light source. A compensating light supply device (11, 14 to 19) is optically coupled via the peripheral surface (13) of the optical element (1) to the latter. It supplies compensating light (16, 12) to the optical element (1) in such a way that the temperature distribution in the optical element (1), which arises as a result of cumulative heating of the optical element (1) with projection light (2) and compensating light (12), is at least partially homogenized. In said manner image defects induced by the projection light are corrected.
