The invention relates to a fuel pump for a fuel system of an internal combustion engine, having a housing and a housing cap joined to the housing. In order to create a fuel pump which in its operation generates little airborne sound, structure-borne sound (vibration amplitudes) and pulsations in a low-pressure region of the fuel pump, it is proposed that the housing cap has at least one damping element, which is embodied as a sandwich construction having at least a first cover layer, a second cover layer, and a damping connection layer disposed between them. The damping connection layer has a markedly higher elasticity and/or higher material damping than the two cover layers, which may be constructed of sheet metal or the housing cap itself.

The invention presents a table system which has an axially oriented plug fastening means (3, 4) between table leg (2) and tabletop (1) and an automatic retaining device (5, 6, 7) which retains the table leg (2) after it is inserted into the tabletop (1). According to the invention, advantages such as a high degree of variability and particular convenience in terns of assembly are achieved.

A table having a stationary supporting device and a movable furniture segment and an operating device for moving the furniture segment is provided. The operating device is swivelably movable about a vertical axis and is operatively connected with the table leaf by at least one control device. The control device converts a swiveling movement of the operating device to a furniture segment movement different from the swiveling movement of the operating device. The table having the control device and operating device is particularly advantageous in for a multiphase movement of the movable furniture segment. A connecting link guide can be used in the control device, particularly implemented in the form of a control cam having a control groove by means of which a furniture-segment-side control pin can be displaced for the movement of the movable furniture segment.

It is proposed for the clutch disc of a motor vehicle friction clutch that one of the lateral discs of a torsional vibration damper of the clutch disc be mounted via a radially resilient mounting ring on a cylindrical bearing face of a hub of the clutch disc. The mounting ring has a closed annular part which is fixed radially and axially in a central opening of the lateral disc and, on its internal periphery, has a substantially conical, preferably radially slotted, radially resilient connecting region. On its internal periphery, the connection region is provided directly or via a shaped-on tube region with a cylindrical opposing bearing face which rests substantially without initial tension on the bearing face of the hub. Spacer blocks limit the radial spring path and are used for the non-rotational guidance of the mounting ring on the lateral disc.

The invention relates to a clutch disc including an idling damping device and an under-load damping device, wherein the idling damping device is active between two hub parts coupled with each other by a toothing having play in the circumferential direction. In order to avoid the load-change impact, centrifugal weights are provided between the two parts. The centrifugal weights frictionally couple the two parts by means of a self-intensifying effect.

The torsional vibration damper suitable for the clutch disc of a motor vehicle friction clutch comprises an idling damper, the springs of which are retained in recesses of a toothing which couple the hub of the damper with a disc part, with limited play in rotation. The end faces of the spring lie for the one part on stop edges of the disc part and for the other part on stop edges of two retaining discs which annularly enclose the hub. The retaining discs are coupled non-rotatably, by axial bent-out portions, with a hub disc of the hub, and for assembly are pushed axially on to the hub. The retaining discs can be produced simply and fitted without problem. FIG. 1.

A fuel pump, including a driven impeller, which rotates in a pump housing and on the two sides comprises guide blades that each delimit a ring of blade chambers, and further including partial ring-shaped channels, which are arranged on both sides in the region of the guide blades in the pump housing and which form delivery chambers with the blade chambers for delivering fuel, wherein an inlet channel leads into the one delivery chamber and the other delivery chamber leads into an outlet channel, and mutually opposing blade chambers are connected to each other. The cross-sectional surface of the partial ring-shaped channel arranged on the inlet side decreases toward the end of the partial ring-shaped channel to zero. The region in which the cross-sectional surface decreases extends over an angular region of more than 45°.

An item of seating furniture including a base, a seat unit with a seat surface, and a leg unit moveable in relation to the seat unit and having a leg support surface. The leg unit is displaceable via a movement mechanism between a storage position wherein the leg support surface is arranged under the seat unit and a use position wherein the leg support surface is arranged in front of the seat unit. The movement mechanism has an intermediate support displaceable via a pivoting guide, wherein the pivoting guide has a pivot lever between the intermediate support and the seat unit or the base, and the movement mechanism has a guide with a sliding member. The sliding member is guided on the intermediate support, and the leg unit is attached to the sliding member.

Device and method for recognizing wanted and/or unwanted telephone calls of a telephone user as a function of the user's behavior. The device has an interface to at least one telephone of the user and an interface to at least one media terminal. A mechanism determines the input of a telephone call on the user's telephone. An examining mechanism establishes a spatial relationship between the user's telephone and the media terminal. A detection mechanism detects the activation state of the media terminal. A tapping mechanism taps the media content playing on the media terminal at the time point of the input of a telephone call on the user's telephone. A comparison mechanism compares the media content during an incoming call on the user's telephone with the media content of Event Files of a User Profile stored in a storage mechanism. A determining mechanism determines whether a call is wanted.

The present invention relates to processes for preparing carboxylic acid derivatives, comprising the reaction of at least one carboxylic acid and/or of a carboxylic acid derivative with at least one alcohol and/or an amine in the presence of a metal-containing catalyst, wherein, after the reaction has ended, the metal-containing catalyst is contacted with water and a superabsorbent, the contacting of the catalyst with the water leading to hydrolysis of the catalyst. The present invention further relates to the use of superabsorbents for removing a metal-containing catalyst from a mixture after hydrolysis of the catalyst.
