Abstract: A latch mechanism includes a housing containing a force transfer member. At one end of the force transfer member, a first cam mechanism is provided which is intended to be rotated by an actuator handle. At the other end of the force transfer member, a second cam mechanism is pivotably mounted to the housing and is pivoted through movements of the force transfer member responsive to rotations of the first Cam mechanism. The second cam mechanism is coupled to a latch bolt so that rotations of the first cam mechanism will result in movements of the latch bolt. The improved latch mechanism is designed to permit complete retraction of the latch bolt through rotation of the first cam mechanism by less than one-twelfth of a revolution, in either direction of rotation.

Abstract: The invention relates to contact strip (16) for slipping over the edge (22) of a wall unit (14), whereby a longitudinal edge (20) of the contact strip is designed cliplike and the contact strip has contact areas (24) bent out of the plane of the strip. The contact areas are formed by a single row, spaced apart from each other, contact tongues (24), stamped and bent out of the plane of the contact strip and by the cliplike longitudinal edge formed with a row of individual clip elements (20) distributed over length of the strip and spaced apart from each other.

Abstract: The invention relates to a viewing screen unit (2) with a viewing screen housing (6) supported swivelably around a swivel axis (4). The viewing screen housing (6) has the shape of a circular cylinder segment, where the viewing screen plane essentially coincides with the intersecting plane (10) of the circular cylinder segment and the pivot axis (4) coincides with the cylinder axis. In a preferred embodiment, the viewing screen housing (6) is fastened swivelably onto a receiving housing (8) containing at least part of the components. The receiving housing (8) is provided with a concave recess (19) turned toward the viewing screen housing (6), which recess fits closely against the curved rear wall of the viewing screen housing. The supporting of the swivelable viewing screen housing is preferably done by supporting means which act on either the inside of the end faces or on the curved back side of the viewing screen housing (6).

Abstract: A process for the continuous production of a sheeting of stratified material from synthetic resin foam particles especially particles of crosslinking polyethylene includes the steps of scattering foam particles onto a conveying means, preheating the foam particles during conveyance, superficially to a temperature in the range between 100.degree. and 160.degree. C.; thereafter feeding the thus-preheated foam particles to means defining a free falling zone; causing the preheated particle to free-fall within said zone; further heating the particles during falling, to a temperature of at least 200.degree. C., and, at the end of the free fall, piling up the particles on a support surface; compacting the piled-up particles into a sheet-like layer on said surface; and sizing the preliminarily compacted sheet with simultaneous cooling.

Abstract: A tape guide having a surface over which a tape is guided. The surface is formed by a coherent network of intersecting ridges whose tops form a smooth continuous surface having a regular pattern of discrete recesses in the surface.

Abstract: A floor mat is formed essentially of cross-linked polyolefin foam for the lining of the floor interiors of motor vehicles. This mat includes a cross-linked polyolefin foam floor mat base having at least one preselected surface area covered with a permanently applied floor-protecting surface layer. The layer is made up of cross-linked polyolefin foam layer and a thermoplastic polymeric film which is heatable in a high-frequency electrical field in dielectric fashion and which exhibits wear resistance superior to the cross-linked polyolefin foam or base. The cross-linked polyolefin foam base is preshaped to conform to the contours of the floor interior of a motor vehicle.

Abstract: A mount for a projector or the like has a base with a convex spherical bearing element rotatably mounted therein and having a guide slot on the convex surface and a concave support rests thereon with a depending pivot pin disposed in a tapered aperture in the bearing and a projection fitting in the guide slot for limiting tilting of the support.

Abstract: A magnetic tape cassette for a tape recorder, having at least one erase interlock device including an actuating member movable over a defined path in the cassette between a operating position in which an opening in the housing is uncovered, and a position in which the opening is closed. The cassette includes at least one latching element preventing movement from a third position and either of the first two positions. Preferably the latch is movable, and in addition the interlock may be set in a fourth position from which it can be moved only upon disassembly of the cassette.

Abstract: An engine hood lining for automotive vehicles has a continuous sheet-like body that is formed of a closed-cell polyethylene foam material and is shaped to fit the inside contour of a hood of the vehicle.
