Abstract:
Proposed is a glare free pan for a rear view service in motor vehicles, possessing a curved transparent substrate, the front surface of which forms the exposed surface of the said mirror. Upon the rear surface of said substrate is applied, in appropriate thicknesses, by sputtering at least four successive and contiguous layers of respectively niobium pentoxide, silicon dioxide, chromium and a protect covering of lacquer. The chromium layer provides the effective reflecting quality of the said mirror. The composition and thicknesses of the layers allows the mirror to reflectively function in visible light wavelengths suitable for both night and day service. Proposed also is a method for the manufacture of the above as well as its assembly into a rear view mirror ready for vehicle installation.
Abstract:
A sliding structure and a joint member, which are provided with a sliding means which substantially eliminates the so-called Stick-Slip effect. This is achieved through the provision of free ends of a plurality of projections, sliding upon the surface of a complementary opposed and facing surface. By appropriately dimensioning the individual free end contact surfaces of the projections and by selectively varying in the number of the projections per area unit, the difference between the initial still-stand holding effect and the sliding friction in the case of selected material pairings is considerably reduced. The force, which is necessary to set the two sliding components into motion, relative to one another, is then only insignificantly greater than the force necessary to overcome dynamic or sliding friction. The Stick-Slip effect is known and unavoidable in a case with a sliding pair of unfavorable materials and, in this manner, can be effectively reduced. The final result is that materials can now be employed in accord with the invention, which are selected for advantageous properties, such as, for example, structural strength. In this way, the expensive installation of an auxiliary sliding plate or special sliding layer is eliminated.
Abstract:
A chain lock has two lock parts which can be displaced in the longitudinal direction of the lock in order to open and close the lock. Each lock part has a journal (6) which is arranged on one end and a pocket (7) which is arranged on the other end in order to receive a journal (6) of the other lock part. Each journal (6) is fitted with at least one retaining web (8) which can be displaced in a retaining groove (11) of the pocket (7) of the other lock part. The journal (6) and the pocket (7) have a cross-section which continuously widens or expands in the longitudinal direction of the lock.
Abstract:
Molding a carrier base from plastic having a curved base surface formed into a fixed shape prior to receiving a mirror coating. Sputtering a first mirror coating layer selected of chromium onto the curved base surface, wherein the first layer has a light reflectivity in the range of approximately 60% to 65% of visible electromagnetic radiation. Sputtering a second mirror coating layer of aluminum onto the first layer so that the second layer has a light reflectivity of at least about 80% of visible electromagnetic radiation and a maximum thickness of approximately 20% of the thickness of the first layer. The first and second mirror coating layers are applied to the curved base surface to have a combined layer thickness in the range of approximately 5 mm to 1 μm. Applying an anti-scratch coating onto the second mirror coating layer to resist damage to the first and second mirror coating layers.
Abstract:
A conical thread structure &agr;1,&agr;2,t is provided to simplify the removal of threads in plastics sleeve elements 1,2,3,4 and to decrease production cost. The radial distance of the thread elements 50,60,51,61 of said thread structure and of the corresponding form tools, which elements being adjacent in translational z or −z direction, are dimensioned such that, when removed E0,E1,E2 or F0,F1 from the mold each thread element “snaps out” only once and does not snap into a second time.
Abstract:
A burner with an electric ignition device, for use in an internal combustion engine, a combustion chamber of a gas turbine set, or for a furnace installation, includes two hollow part-conical bodies that are positioned to form a conical combustion space and are offset so that longitudinally extending, tangential inlet slots are formed to conduct combustion air into the combustion space. Inflow orifices provided at the tangential inlet slots feed fuel to the inflowing combustion air to be mixed and carded into the combustion space. An electric ignition device is positioned so that spark producing ends are positioned at a central vertex region of the combustion space. The position of the ignition device protects the device from excessive thermal loading, and allows the burner to be operated at a higher, more efficient temperature.
Abstract:
A valve spring retainer and locking assembly comprising a locking member which is made screen-like and engages at least one peripheral groove of a valve stem end in a manner known per se employing a bulge, and is pressed against the valve stem end via a conical outer surface in interaction with a valve spring retainer. The locking member has the conical outer surface on the outer periphery of an umbrella-like support surface and also has a cylindrical contact surface with the valve stem on the groove side facing towards the free valve stem end. The valve spring retainer is supported against the screen of the locking member, is made of fiber-reinforced plastic and in the area of the conical outer surface of the umbrella-like support surface has a conical step which leaves an impression on the run of the fibers and, in interaction with the conical outer surface of the locking member, presses the locking member against the stem.
Abstract:
A display system and method for displaying an image to the driver of a vehicle, in particular a commercial vehicle. The display system has a capturing device mountable to the vehicle and adapted to capture at least part of the vehicle's immediate environment, and to generate signals corresponding to the captured part of the vehicle's immediate environment, a calculation unit adapted to receive the signals generated by the capturing device, determine obstacles within the captured immediate environment of the vehicle, and generate a display image illustrating the vehicle in stylized or symbolic representation, and the obstacle identified in the vehicle's immediate environment as well as its relative position with regard to the vehicle, and a rendering unit adapted to display the display image generated by the calculation unit within the vehicle and visible for the driver.
Abstract:
A mirror replacement system for a vehicle includes an image capture unit, a supply unit configured to supply the image capture unit with control signals, and an image reproduction unit configured to be disposed in the vehicle interior. At least one of the supply unit and the image capture unit is configured to perform video processing of the images captured by the image capture unit. The image capture unit and the supply unit are disposed in spaces separated from each other with respect to their sealing and are each disposed separated from and outside the image reproduction unit. The image capture unit is disposed in a water-vapor-tight housing, and a heating element may be integrated into the image capture unit, the heating element being controlled by the supply unit and being coupled to at least one of temperature detecting elements and vehicle control elements.
