Abstract: An apparatus for fighting a fire comprises a suspendible container having a perforated lower surface each of whose perforations is closed by a heat-sensitive membrane rupturable at an elevated temperature. The container contains a fire retardant material which is released upon rupture of the membrane. The apparatus further includes an electric heater adjacent to the membrane and a smoke detector controlling the heater such that upon the detection of smoke, the heater is switched on to rupture the membrane. A second embodiment has at least one further heat-sensitive membrane embedded in the fire retardant material above the first membrane such that a respective layer of fire retardant material lies above each membrane.

Abstract: A ceiling tile contains a plurality of shells made of a thin membrane and filled with fire retardant materials. When the shells are subjected to high temperatures, as when a fire is present in the room, the shells burst and release the fire retardant materials to extinguish the fire.

Abstract: A process for making inflatable tires Puncture Proof.wherein air filled spheres or bubbles (2) are coated with a quick drying glue (10) before being inserted into a mounted, deflated tire, which is then inflated and rotated at high speed to create the centrifugal force needed to disperse spheres (2) evenly while the glue (10) dries and also to balance the wheel (8) without the use of weights.

Abstract: An adaptor allows a known fishing pole to receive at least two fishing reels for being simultaneously used. The adaptor includes a mounting foot that is designed to be received in the structure of the known pole that receives a single fishing reel. Another part of the adaptor is designed to receive the two or more fishing reels and to support them on the fishing pole.The two reels may be used to fish at large distances by attaching a conveying device, for example a balloon, to one of the lines. The second of the lines passes through a ring attached to the first line for carrying the second line away from the fisherman.

Abstract: A slip-on self-locking automatically articulating emergency brakeing system for ladders is described.Consisting of a metal plate as the complete raw material required for the manufacture of a set of two brakes, one brake designed to fit the left hand side rail, and one brake designed to fit the right hand side rail of said ladder.A plurality of protrusions diverge from the body (22) of each brake, including a jug handle type lug (20) which most nearly encircles a rung of said ladder, a slide plate (12) which engages the rear portion of said ladder rail.A slide plate clasp (14) to prevent lateral movement of the device, and structuraly induced incisor column (10) and incisor (8) for use as a perpendicular brakeing mechanism due to right angle reduction.

Abstract: A vehicle usable in the air, on water, or on ground is described. Outer wing portions are connected to a central portion by a mechanism which allows the outer wing portions to pivot about first axes for placing the outer wing portions in stored positions. The outer wing portions are also rotatable about a second axis for placing them in positions whereby they are useful as sails for driving the vehicle without the use of an engine. The wheels are capable of being pivoted to non-positions.
