A fluorescent bulb retaining spring (6) comprises a one piece, sheet-metal stamped and bent part, entirely and seamlessly comprised of one material. The retaining spring (6) can be produced especially simply from one rectangular piece of sheet metal of substantially uniform thickness, with all functional parts and functional regions created by cutting out spring tongues and bending them outwardly from the sheet. Connecting legs between a bulb retainer portion (9) and a fastening portion (8) form an annular region which is closed in force-locking fashion by a crimped connection (29, 31, 32), which can be produced in automated fashion as part of the stamping and bending operation.

The invention relates to a compressible and expandable blade for the rotor of a fluid pump having at least two lamellae which are disposed adjacently, are pivotable respectively relative to an axis of rotation of the rotor and moveable relative to each other, and abut against each other in the expanded state of the blade such that they form together a continuous blade surface.

A head part (11) for a multi-chamber tube bag (1) with a multi-component mass which can be pressed out, having a main chamber (2) for a first component and two secondary chambers (3, 4) for two other components, has a disk-shaped contact surface (12) for the multi-chamber tube bag (1) surrounding a press-out opening (13). At the contact surface (12), a plurality of raised portions (14) project toward the multi-chamber tube bag (1) and are provided at the head part (11) for narrowing the outlet regions (5, 6) of the two secondary chambers (3, 4) of the multi-chamber tube bag (1) when the multi-chamber tube bag (1) bears against the contact surface (12).

A female component of a press stud including a monolithic body made by hot forming and defining a housing seat for a retaining member housed in the housing seat and intended to lock a corresponding male component in position selectively during use. A locking lip, integral with the monolithic body, extends from the housing seat and is deformed so as to partially close the housing seat in order to secure the retaining member therein. In order to produce the female component, the monolithic body is hot formed, and the locking lip is deformed after the introduction of the retaining member into the housing seat, by hot or cold crimping, upsetting or deformation in general.

Disclosed is a photocatalyst comprising a photocatalytically active base, and a silicon oxide film covering the base and substantially having no pores. The alkali metal content of the photocatalyst is not less than 1 ppm but not more than 1,000 ppm. Also disclosed is a method for producing such a photocatalyst wherein when a photocatalytically active base present in an aqueous medium is coated with a silicon oxide film by using a silicate, the pH of the aqueous medium containing both the photocatalytically active base and the silicate is maintained at 5 or below.

A hollow profile (1) formed of a flat material (31) having a width (d) has at least one groove (6.1, 6.2, 7.1, 7.2) provided on an outer side of at least one of the plurality of walls (2.1, 2.2, 5.1, 5.2) of the profile (1) and having a bottom (8.1, 8.2, 9.1, 9.2) spaced form the outer side by depth (t) and two opposite, substantially flat side walls (13.1, 13.2, 40.1, 40.2) extending substantially perpendicular to the bottom (8.1, 8.2, 9.1, 9.2), with the groove depth (t) of the at least one groove (6.1, 6.2, 7.1, 7.2, 32) amounting to from 0.5 to 2 times of the material thickness (d) of the flat material (31).

A motor vehicle door has a lateral impact protection device with a lateral impact beam and a fastening device to connect the lateral impact beam to a door part. The fastening device has a fastening bracket being a cast part and is connected to the door part. The fastening bracket has a fork-shaped seat for receiving the lateral impact beam. A holding bolt passes through the lateral impact beam and the fork-shaped seat. The fork-shaped seat contains at least two inner surfaces which face the lateral impact beam and lie opposite one another with a spacing and a fork bottom. For ease of production, the fork-shaped seat widens with its inner surfaces in its direction pointing away from the fork bottom. The inner surfaces are configured as unfinished cast surfaces, and the lateral impact beam has a trapezoidal cross section adapted to the widening seat.

A pull tab for zippers is formed by a cord having a cord retaining member attached to one end of the cord and a socket in the top surface of the cord retaining member, and a plug attached to other end of the cord. The plug has a shape corresponding to the shape of the socket, so that the plug can fit securely within the socket, thus, forming a loop with the cord. A slidable locking device is placed around the cord, the locking device having an interior cavity corresponding to the shape of the cord retaining member, such that placing the plug into the socket and sliding the locking device over the cord retaining member locks the second end of the cord to the cord retaining member. In a method for manufacturing the pull tab, the plug and cord retaining member are continuously overmolded in one piece on a length of the cord, and then cut into pieces to form completed pull tabs.

The invention relates to a piston pump for conveying a fluid, in particular in a vehicle brake system. The piston pump has a cylinder and a piston movably disposed in the cylinder. A restoring element preloads the piston, and a drive unit for actuates the piston in the cylinder to pump the fluid into a pressure chamber formed in the cylinder. The piston is embodied by a first piston par and a second piston part. The first piston part is a cylindrical body, which can be moved by the drive unit. The second piston part form the piston base, in which four radial inlet openings and one axial connection opening for communication with the pressure chamber are disposed. A flange for the disposition of a seal is disposed on the outer circumference of the piston base element. The openings are simple to make in the face ends and circumferential regions of the second piston part.
