METHOD OF PRODUCING A COATED VEHICLE WINDSHIELD FOR A HEAD-UP DISPLAY (HUD)
20210107256 · 2021-04-15 ·

A method for determining pane thicknesses and a wedge angle of a coated windshield for a projection arrangement of a head-up display. A wedge angle and a combination of glass thicknesses are determined by means of which the glass ghost image and the layer ghost image are optimally reduced. The method proceeds from a starting thickness of the two glass panes of the windshield for which that wedge angle is determined, in an iterative process, that represents an optimal compromise between the minimization of the glass ghost image and the minimization of the layer ghost image. Then, the glass thicknesses are determined varied within a specified range for each combination of the optimal wedge angles. Thus, it is possible, iteratively, to identify that combination of glass thicknesses that results in the least occurrence of ghost images, in addition to the associated optimal wedge angle.

Sleeper for a Track Superstructure
20210140120 · 2021-05-13 ·

The invention relates to a sleeper for the track superstructure, which is manufactured in one piece from a plastic material, with the sleeper having an elongated base shape with two end sections, which are connected by a middle section of the sleeper and held at a distance and on their upper side in each case one contact surface is provided for in each case one rail to be supported on the respective end section with a reinforcement extending in the longitudinal direction of the sleeper being embedded into the middle section. In order to design such a plastic sleeper such that it has optimised strength and can be reliably manufactured even using cost-effective plastic/sand mixtures having a high proportion of sand, the invention proposes that the reinforcement extends over the length of the middle section, that the reinforcement is in each case anchored in the respective end section an edge region of the end sections assigned to the middle section and in that the reinforcement is wholly or partially arranged in the upper quarter of the height of the sleeper.

Inductor element

An inductor element includes a wire-winding portion and a core portion. In the wire-winding portion, a conductor is wound in a coil shape. The core portion surrounds the wire-winding portion and contains a magnetic powder and a resin. An inner-core central region is a region of the core portion within a distance from a winding axis center of the wire-winding portion toward an existing region of the wire-winding portion in an outward direction perpendicular to the winding axis center. A top-plate central region is a region of the core portion within a distance from the winding axis center toward a no-existing region of the wire-winding portion in the outward direction. Sα−Sβ≥−2% is satisfied, where Sα (%) and Sβ (%) are respectively an area ratio of the magnetic powder in the inner-core central region and the top-plate central region.

20210078213 · 2021-03-18 ·

A technique of manufacturing an elastomeric container closure or plunger with embedded functional components to avoid thermal damage to the components is described. The technique includes molding a drug-contacting part from a first material at a first temperature and for a first length of time defining a first thermal exposure; after molding the drug-contacting part, inserting ancillary components into the drug-contacting part, where the ancillary components have an operational thermal budget less than the first thermal exposure; and overmolding the drug-contracting part and the ancillary components with a second material at a second temperature for a second length of time to form a non-drug-contacting part that mechanically connects the non-drug-contacting part and the drug-contacting part to form the elastomeric container closure and seals the ancillary components inside the elastomeric container closure. The overmolding defines a thermal exposure less than the operational thermal budget of the ancillary components.
