Abstract: A sun blind assembly including an incident surface and a lens element, the incident surface having a reflective region which reflects incident light and a non-reflective region which transmits incident light, the lens element and incident surface being arranged such that the transmitted light incident on the lens element is substantially refracted so as to appear of substantially uniform intensity

Abstract: A unique adhesive composition consisting of two parts, a resin and a curing agent, is disclosed. The composition has good adhesion to chemically inert substrates, both flexible and rigid. It is useful for sealing discontinuity in concrete slabs, tanks, decks, pipe lining or combinations thereof.

Abstract: A reinforcement module for a vehicle door comprises a plurality of elongate reinforcement members (1) and a plurality of connectors (2a, 2b and 2c). Each connector (2a, 2b and 2c) is engageable with the free end portions of at least two of the elongate reinforcement members (1) to connect those elongate reinforcement members together. The arrangement is such that at least one of the elongate reinforcement members (1) extends generally transversely with respect to at least one other elongate reinforcement member.

Abstract: A sealing member in the form of an elastomeric cap serves to seal the joint between a reflector body and a light bulb which is inserted into the back of the reflector body. To enable breathing of the lamp unit, the sealing cap is formed of a resilient, elastomeric material and has a normally closed slit therethrough.

Abstract: To facilitate aiming of a motor vehicle headlamp, e.g. as specified in U.S. Lighting Standard SAE J602, a motor vehicle headlamp having a housing with a light-transmitting front cover and a lamp reflector body mounted completely within the housing has an abutment carried by a rod at the top of the headlamp. The rod is slidable in bearings and connected with an adjusting screw for the lamp reflector body so that adjustment of the screw also moves the rod. A conventional mechanical headlamp aimer in mounted on the light-transmitting front cover of the housing in known manner and engages against the abutment.

Abstract: A lamp reflector comprises a dished body having a front opening and a rear aperture for a bulb having a filament. The dished body has an upper paraboloid reflective surface subtending an angle of about 165.degree. at the optical axis. The body also has a lower paraboloidal reflective surface whose optical axis is coincident with. The filament lies on axis. The filament lies in front of the focus of the upper reflective portion but behind the focus of the lower reflective portion. The reflective portions and define an upwardly inclined step portion and a horizontally disposed step portion.

Abstract: A high aspect ratio passing beam headlamp has a body provided with front opening and a rear opening which is displaced below the horizontal median line of the headlamp. Within the body is a pair of lateral curved reflective portions and separated by an upper curved reflective portion. The foci of the reflective portions are coincident. A bulb is mounted in the rear opening. A U-shaped bulb filament shield rests against a lower planar portion of the body and has arms which provide a horizontal cut-off on both sides of the bulb.

Abstract: A diffusion cover for a motor vehicle headlamp comprising upper and lower mutually inclined translucent cover portions are integrally joined together to define therebetween a ridge on an outer surface of the cover and a trough on an inner surface of the cover.

Abstract: A vehicle headlamp has a reflector provided with a reflective area lying on a surface defined by rotating an ellipse about an axis which passes through the inner focus of the ellipse and which is inclined an acute angle (1.degree.-2.degree.) to the focal axis of the ellipse. A shielded filament for producing an inclined cut-off line to the beam is used and is orientated in the opposite sense to that in which it is orientated in a conventional headlamp for producing an inclined cut-off. To produce a Z-beam pattern, lensing at the front of the reflector splits the area of the basic beam pattern immediately below a horizontal portion of the cut-off line into parts which define upper and lower, mutually laterally displaced horizontal cut-off portions in the required Z-beam pattern.
