Abstract: A gear crank for a bicycle includes a plurality of chain gears mounted to stays disposed radially outwardly with respect to a crank shaft. The stays include four main stays arranged in pairs. The two main stays forming each pair are disposed at a relative phase difference of about 180.degree.. Two short auxiliary stays are disposed between the pairs of main stays and have mounting portions for the larger diameter chain gears. The pairs of main stays intersect at a non-90.degree. angle so that an angle between the pairs of main stays is larger than that between the main stays forming each pair. The stays are fixed to the crank to position the crank arms between the pairs of stays within a region defined by the above-described larger angle respectively. Connecting segments extending circumferentially and supporting the auxiliary stays are provided between the auxiliary stays and the main stays adjacent thereto respectively.

Abstract: A process is provided for continuously manufacturing plates containing an open net fibrillated polymeric film reinforcement. A net having a plurality of fibrillated polymeric film layers is unwound from a continuous reel, and the net is cut into pieces having a length approximately equal to a circumference of a forming roll for forming a plate to be manufactured. The net pieces are impregnated with a cement mix and then deposited onto a conveyor belt on which a cement mix layer has been previously deposited. After contacting the net with the cement layer, the net is subjected to vibration. A vacuum is applied to the net contacting the cement layer to remove excess water and to increase the compactness between the net and the cement layer.

Abstract: A coiled rope providing a securely coiled rope structure which, when forcefully uncoiled, gives rapid yet controlled deployment of the rope, and a method of so coiling the rope. The rope is wound about a central core member in sequential, adjacent, planar circular layers of approximately similar diameter, each layer consisting of a plurality of coils of rope of increasing size commencing from the central core member. Adjacent coils of rope in each layer and adjacent layers of rope are releasably adhered to each other by contact cement so that the rope will remain securely coiled in storage or until required for use, and then permit rapid yet controlled uncoiling of the rope. Such a coiled rope is useful in providing controlled pay out of rope, for example, between life rafts being air dropped to survivors in the sea, the rope being payed out sequentially coil by coil and layer by layer.
