摘要:
The aim of the invention is to increase hearing aid packing density. To this end, at least two elements that are to be assembled on the hearing aid and that are produced from different materials are produced by two- or multicomponent injection molding. For example, in the case of a two- or multipart shell of a hearing aid, the sealing (7a) is coinjected on a part (1) in the marginal area (3) together with the material of said shell part.

An apparatus for applying a coating of solid particulate powder to the interior surface of tubular, cylindrical articles (3) comprises an improved conveyor (65) for transporting the articles (3) to and from a powder spray station (16) whereat powder is sprayed into one open end of the articles (3). The improved conveyor (65) comprises an endless belt conveyor movable in a direction perpendicular to the spray from the nozzle (7) and the axes of articles supported on the conveyor (65). The articles (3) are supported on the conveyor (65) by lugs (69) in the form of rollers which support the articles (3) in grooves (67) defined between adjacent pairs of lugs (69).
摘要:
The bogie for track vehicles, which is used for at least one body, comprises at least two axle sets. Each axle set (2, 2') is arranged in its own support frame (3, 3'). The support frames (3, 3') are connected to one another by spring bodies (5). The support frames (3, 3') are symmetrical and can pivot mutually by means of a vertical bearing (7). The spring bodies (5) have a primary shock-absorbing effect. The support frames have the shape of symmetrically-arranged U-shaped half-frames (3, 3') and rest on one another in a flexible manner by means of their projecting arms (4, 4'). On bends, there is consequently no movement in relation to the axle sets (2, 2'). The design, which is essentially identical for motor-equipped and non-motor equipped bogies, can be adapted for any selected bogie arrangement. When small-diameter wheels are used, the vehicle floor can be kept very low, facilitating the boarding and alighting of passengers, and ensuring a high level of directional stability.
