Abstract:
A method for producing luminous means proposes providing a carrier serving as a heat sink, said carrier comprising a planar chip mounting region. The planar chip mounting region is structured for the purpose of producing a first partial region and at least one second partial region. In this case, the first partial region has a solder-repellent property after structuring. Afterward, a solder is applied to the planar chip mounting region, such that said solder wets the at least one second partial region. At least one optoelectronic body is fixed into the at least one second partial region with the solder at the carrier. Finally, contact-connections are formed for the purpose of feeding electrical energy to the optoelectronic luminous body.
Abstract:
Layered composite materials which comprises a substrate made from a thermoplastic polymer, and comprise an intermediate layer arranged thereupon and a decorative layer applied to the intermediate layer, where the decorative layer is composed of a chromed metal. A heat-cured layer may moreover be applied to the decorative layer. Layered composite materials of this type are suitable, inter alia, as reflecting or insulating parts of household devices or of moldings in the electrical, construction or automotive industry.
Abstract:
A pressure feed in a shaft (1) of a transmission with a hydraulic or pneumatic control device through which the pressure feed can be acted upon with the pressure medium, with a gearbox (2), in which the shaft (1) is positioned through at least one bearing (3), whereby the gearbox (2) has a beating bore (4) in the region of the bearing (3) and whereby the bearing (3) is affixed axially in the gearbox (2) using a retaining sheet (5), with a gearbox cover (6) which covers the bearing bore (4) of the gearbox (2) and has feeding bores (7, 8) through which the pressure medium is transmitted from the hydraulic or pneumatic control device to the shaft (1). A pressure line (10) consisting of a tube (11) and a connection piece (12) inseparably connected pressure-tight to the tube be arranged between the hydraulic control device and a feeding bore (8) of the gearbox cover (6) arranged parallel to the shaft (1). The detachable connection piece (12)is separably inserted pressure-tight into the feeding bore (8) of the gearbox cover (6) running parallel to the shaft (1) and has a collar (13) for axially affixing the pressure line (10) in the gearbox (2). The retaining sheet (5) of the gearing (3) affixes the bearing (3) in the gearbox (2) as well as the pressure line (10) through the collar (13) of the connection piece (12) axially in the gearbox (2).
Abstract:
The invention relates to a method for producing hollow nickel titanium profiles with a small external diameter and/or small wall thickness by means of deformation, especially extrusion. According to the inventive method, a composite block is formed, comprising a solid core and one or several hollow blocks surrounding said core. The core and the hollow blocks are made of nickel titanium. The parts of the composite block are separated after deformation to obtain a wire (3a), a tube (1a) with a small diameter and a tube (5a) with a larger diameter.
Abstract:
A multilayer laminated material which comprises at least one layer of glass and which has improved thermal stability is distinguished in that it comprises a lower substrate layer of a plastic, a metal or a combination of plastic and metal, an intermediate layer arranged thereon and comprising a soft material or comprising a thermoplastic, a further fibrous intermediate layer comprising plastic, which is provided with a solvent-free adhesive material, and a top layer of glass. The multilayer laminated material is suitable for the installation of glass elements in the area of the electrical, the electronics and the automotive industry and for other industrial applications.
