Abstract: Belt-braking system for safety belts having the known automatic roll-up device with a locking device followed by a belt brake. The belt-brake has a rotatably supported brake roller which is partly wrapped around by the belt. Friction or positive locking means arrest the brake roller when activated by a belt pull which exceeds a predetermined force.

Abstract: Belt lock for a safety belt with a spring-operated locking catch with hooked part engaging a plug-in tongue. A hand-operated member has a locking part in fixed connection. The locking part is disposed in the path of motion of the hooked part preventing release of the tongue unless the member is pressed by hand to move the locking part out of the path of motion. The locking part is movable along the plug-in axis; and the locking part in the closed position couples with the locking catch.

Abstract: Belt-lock and plug-in tongue for a safety belt having a locking mechanism with two locking latches for locking the tongue, tensioned against each other by a spring, and with one locking latch disposed on each side of the plug-in tongue. A hand-actuated member is movable against disengaging means of the locking mechanism to simultaneously move the two locking latches out of engagement with the tongue to permit removal of the tongue from the lock-housing. This assures symmetrical absorption by the belt lock through the latches of forces introduced by the belt system, and also equal distribution of the pulling forces to both locking latches so that the effective forces at each locking latch are halved.

Abstract: A high voltage, electrically-activated flashlamp which includes an improved ignition means comprising a pair of lead-in wires, a glass or ceramic insulator positioned on the ends of the wires, and a plurality of spark gap members arranged in either an annular or linear pattern with the lamp's envelope for simultaneously igniting the lamp's shredded zirconium or hafnium combustible material. The spark gap members, each comprising a pair of spaced (or gapped) layers of aluminum or copper bridged by a small quantity of high voltage breakdown primer material, are electrically connected in series.

Abstract: A disk-shaped flashlamp unit for use within an indexing means or mechanism associated with a camera. The unit includes several, e.g. ten, electrically-activated flashlamps radially disposed within the unit's plastic, light-transmitting housing. A pair of planar reflectors are utilized for each lamp to reflect the light therefrom through the housing. Light output can be further enhanced by utilization of two additional planar reflective members adjacent each lamp, the four members surrounding the side and bottom portions of the flashlamp's envelope to thereby direct light emitted from the flashlamp in a substantially singular direction through the peripheral region of the plastic housing. The invention's reflectors also assure prevention of sympathetic ignition.

Abstract: A photoflash lamp having a glass envelope with a clear protective exterior coating comprising a photopolymer reinforced with glass fibers. In applying the coating, a long strand of glass fibers is wrapped about the lamp envelope, which is then dipped in a liquid photopolymer, or short lengths of glass fiber are dispersed throughout the liquid photopolymer, either by premixing or application after dipping. The wet-coated lamp is then cure-hardened by a short period of irradiation with a source of ultraviolet light.

Abstract: Safety belt roll-up device with a release mechanism which in case of danger activates a control disk and locking means which block the belt shaft. A cam having an actuating dog for actuating the locking means is associated coaxially with the control disk and rotatable relative thereto. A spring holds the dog in a predetermined starting position relative to the control disk, which spring can be deflected resiliently relative to the control disk in opposite directions of rotation. Because of its ability to be deflected in oppsite directions, a single type roll-up device will serve where previously right and left devices are needed.

Abstract: Retightener with a pyrotechnic propellant charge for automatic safety-belt wind-up devices having an energy converter, wherein in the event of danger the explosive pressure of the ignited propellant charge acts on a pullout element tightening the safety belt around the body of the vehicle passenger to be protected via a liquid buffer arranged between the propellant charge and a pullback element. In accordance with the invention a receptacle which contains the liquid buffer is coupled to the winding shaft and rotates together with the latter. In the circumferential surface of the receptacle is at least one jet nozzle directed substantially tangentially to the axis of rotation and against a stationary guide ring surrounding the receptacle.

In accordance with the invention a turbine housing is disposed around the turbine wheel with a hollow space on one side between the turbine wheel and the wall of the housing to form a turbine pressure chamber. A receptacle containing liquid medium has its outlet opening into the turbine pressure vessel. The outlet of the receptacle is aligned substantially tangentially to the turbine wheel.

Abstract: Automatic wind-up roller for a safety belt with means to stop the belt from unwinding in case of danger. The wind-up roller has a release mechanism activated when a predetermined acceleration or deceleration is exceeded, a control lever activated by the release mechanism, a control disc with elastic yielding control teeth which couple with the control lever, and a locking mechanism activated by the control disc to block the control shaft.

Abstract: A flash lamp which is electrically activated using capacitive coupling between a pair of conductors located externally of the lamp's glass envelope and a respective pair of conductors located within the envelope. A quantity of primer material, also located within the envelope, serves to ignite the flash lamp's combustible material (e.g. shredded zirconium). The primer material is electrically joined to the internal conductors through either a pair of spring contacts or the shredded combustible material.

Abstract: A photoflash lamp unit having an array of eight flash lamps located on each of two opposing sides thereof. Each array comprises two regions, upper and lower, of four lamps. A pivotal mounting device at a lower end of the unit permits the four lamps in one upper region to be fired after which the entire unit is rotated and the four lamps in the remaining, opposing upper region are fired. The unit is then inverted and the eight lamps in the two previously lower regions are fired in the manner described above.

Abstract: A safety belt wind-up roller includes a winding shaft for a safety belt, a rewind spring operatively connected to the winding shaft for rewinding the safety belt after it has been withdrawn, a compensating device for equalizing the restoring force of the rewind spring as the restoring force increases with increasing withdrawal of the safety belt, and a coupling member operatively associated with the winding shaft for rotation therewith, and the compensating device has a compensating member in the form of a roll spring mounted axially parallel to the winding shaft and having a radially outer end forcibly engageable with the coupling member during rotation of the winding shaft over a predetermined rotary angle as the safety belt is being rewound.

Abstract: Passive restraining system for securing a seated vehicle passenger with a safety belt firmly holding the passenger in his seat includes vehicle parts displaceable relative to one another in dependence upon a retardation in the vehicle velocity, for tightening the safety belt which is connected to the vehicle parts.

Abstract: An elongated flash lamp assembly which is sequentially advanced through a camera to permit each of the lamps within the assembly to become aligned with the camera's fixed reflector. Several heat-responsive (e.g. fusible) covers are located on the assembly's housing to permit the above advancement only after each cover has become physically deformed by the heat from the respective flash lamp located adjacent thereto. A mechanism for advancing the assembly is also disclosed.

The sheet and stencil, in the form of a "sandwich", are positioned on the copier's cover member which is then pivoted to a closed position against the copier's housing. A flash lamp article, including a tapered casing having a percussively-ignitable flash lamp therein, is inserted within the housing and activated by a resilient cantilever member located therein.
