Abstract: A tape hub connection assembly, and a magnetic tape cassette containing such an assembly, in which an end of a length of tape is fixed to a reel hub by a clamping member pressed into a hub recess. The clamping member has a tool recess extending radially from the outer wall, for engagement by an assembly or an extraction tool so that the member is easily put in place or removed by a tool extending radially between the reel flanges.

Abstract: A magnetic tape cassette of the "flip-over" type having side-by-side reels in a housing between two parallel main walls, an exposed run of tape along a front of the cassette housing, and a pivoting cover for the exposed run of tape. A single cassette cover covers the entire front of the housing, and has a pivoting arm at each side which is journalled to the cassette housing sidewalls such that the cover can be opened from its closed position in either direction to two different open positions, by pivoting toward the one or toward the other main wall of the housing. A movable slide may also cover openings which provide access behind the stretch of tape.

Abstract: A magnetic tape drive system for a video cassette recorder comprises a flip-over magnetic tape cassette having side-by-side reel hubs, each hub having a disc-shaped centering and drive member in the center of the hub with a central centering aperture and one or more drive apertures at some radial distance from the centering aperture, and a drive arrangement with drive spindles having a centering pin for the centering aperture in the reel hub, and at least one resiliently depressable drive pin which engages a drive aperture. To ensure correct positioning and drive of the spools and an excellent lace-up, and prevent undesired variations in the tensile stress in the magnetic tape and thus variations of the stretch of the magnetic tape, the reel hubs are resiliently urged onto stop surface which rotate with the drive spindles. The resilient urging devices and drive apertures are arranged to prevent disturbing forces on the reel hub.

Abstract: An adhesive interior or dome lining is provided for the interior of a vehicle roof with the central portion of the dome lining being adhesively secured to the roof while free edges of the dome lining are inserted into the gap formed between the roof and the interior roof strut. A profiled member of a soft foam material is provided adjacent the gap with the free end of the dome lining passing over the profiled member to be clampingly engaged into the gap by the compressive forces of the foam material. A method for installing this arrangement is further provided.

Abstract: A self-supporting interior lining or vehicle dome having in the edge zones thereof at least one clamping or mounting bead adapted to cooperate with at least one undercut provided in the vehicle roof structure to mount the same thereon. At least one of the clamping bead and vehicle dome or a portion thereof is manufactured of an elastic material to facilitate installation within the vehicle.

Abstract: An interior covering for automotive vehicles, containers, or the like, which is insulating and optionally constructed to be self-supporting, comprising at least two sheets of polyethylene foam of identical or different density permanently bonded together with a reinforcing polymer-containing layer to form a multiple-layered structure.

Abstract: A process for joining abutting thermoplastic synthetic resin foam structures by a strip which covers a junction zone formed between the foam structures including the steps of pressing a metal strip heated to above the softening point and or the melting temperature of the synthetic resin foam under slight pressure onto the junction zone and then allowing the metal strip to cool. In this manner, a bond is formed between the foam structures and the metal strip.

Abstract: A process for the production of multiple-layer sheets, panels, shaped articles, or the like laminates having at least one layer of polyurethane foam material wherein at least one side of the polyurethane foam layer is bonded under the action of heat to a layer of cross-linked polyethylene foam material.

Abstract: A process and apparatus for continuous production of molded sheets of a foamed thermoplastic synthetic resin, wherein a synthetic resin is fed into a screw extruder and a low boiling point liquid expanding agent is introduced under high pressure into the extruder and admixed with the resin in the extruder and thereafter the resulting admixture is extruded in the form of a plurality of foam filaments to insure proper distribution of the admixture to the nozzles of the extruder. A gear pump is provided for each nozzle. Also, to avoid collapsing of the foam means are provided for tempering the foam filaments by the application of heat.
