A hot-melt adhesive contains a non-pressure-sensitive adhesive that is fluid at application temperatures and that is removable, residue-free, by peeling at small peel angles. The adhesive contains additives selected from the group consisting of fillers, stabilizers, dyes, carbon black, and moisture absorbents. The adhesive also containing the following: a) thermoplastic elastomers that may be grafted, b) grafted and poly-&#x3b1;-olefins, c) polyisobutylene or a softening oil, d) adhesive resin, and e) end block resin.

Releasable adhesive for attachments of substrates and joints

A headlight for a motor vehicle in which an interior space is enclosed by a housing and a cover lens. The interior space communicates with the surrounding outside atmospheric air through a duct that has an inlet opening and an outlet opening. The duct contains reversably-acting hygroscopic desiccating substance which provides less resistance to flow of air into and out of the interior space, than any other leakage points in the headlight. The duct has a portion projecting into the interior space, and has a substantially high permeability for water molecules in a mixture of water-vapor and air. This portion of the duct resists air flow in establishing pressure equilibrium between the inlet opening and the outlet opening of the duct, so that at least a larger part of air in the duct passes through the inlet and outlet openings. One of these openings is in the interior space, whereas the other opening is located in the atmosphere. The aforementioned portion of the duct inhibits transmission of air through walls of the duct, so that maximum air flow passes through the hygroscopic desiccating substance.

Headlight for vehicles, in particular motor vehicles

The present invention relates to a headlight for vehicles with an interior space enclosed by the reflector and the front cover lens or by the housing and the front cover lens, containing air which is in communication with the atmospheric air surrounding the headlight through the inlet and outlet openings of a duct which is formed by a tube, fabricated from substantially air-impermeable material, projecting from the outside into the interior of the headlight. A reversibly-acting hygroscopic desiccating agent is filled into the duct which provides only a slight resistance to the flow of air into, or out of, the interior of the headlight. The desiccating agent contained in the duct has such an area of contact with the moist air within the headlight that it will absorb enough of the moisture from the air within the headlight, even during the periods of time when the motor vehicle is standing idle, so that condensation of water within the headlight, due to falling temperature, will be avoided. The present invention achieves this object by providing several openings in the walls of the end section of the tube, which projects into the interior of the headlight, to enlarge the contact zone between the desiccating agent and the air within the headlight.

An automotive headlight with a bowl-shaped plastic reflector. The reflector has at its apex an opening surrounded at the rear of the reflector by a sheet-metal retaining ring. The ring accommodates an incandescent lamp. The lamp is inserted into openings in the reflector with its securing tabs bent back toward the reflector and is secured to the reflector by barbs on the securing tabs that engage the edges of the holes. To improve the headlight to the extent that the openings in the reflector that accommodate the securing tabs are large enough not to shorten the life of the tool and do not need to be produced with such a precise tolerance, while still ensuring that the retaining ring will fit the reflector reliably and snugly, the securing tabs are bent into a U and the openings in the reflector that accommodate the tabs are quadrilateral and approximately as high and as wide as the tabs.
