Patent ES-421009-A1 (ES)
Title: Safety system for hydrofoil craft
IPC: B63B1/30
Filed: 1973-11-30
Abstract: A hydrofoil craft having foils carried on struts, the struts being supported for pivotal movement relative to the hull of the craft and held in position during foil-borne operation by a substantially rigid restraining device. The restraining device constitutes a mechanical fuse device which holds the strut in place during normal operation but ruptures or yields in response to impact forces on the strut to permit the strut to pivot in case it should strike an object in the water during high speed operation. The pivotal movement of the strut reduces the dangerously rapid deceleration that would otherwise occur and minimizes structural damage to the craft.

Title: Rotary tubular kiln and satellite cooler therefor with improved support means
IPC: F27B7/40
Filed: 1978-12-04
Abstract: Individual suspension of satellite cooling tubes with the aid of wire cables in the region of the discharge end of a revolving tubular kiln in two support locations spaced apart on the axial direction. Each suspension unit comprises a number of suspension elements selectable according to the operative requirements. These elements preferably include three pretensioned wire cables anchored to suitable retaining elements secured to the kiln casing. In a preferred embodiment, the wire cables are arranged so that two of them exert upon the associated cooling tube a tractive force, the resultant of which is oriented towards the kiln axis, whereas the third wire cable, which is anchored by at least one resilient element, applies to the cooling tube a force directed in opposition to the resultant and of equal value. Due to a uniform application of forces by the wire cables at the shell of the cooling tubes, and in the absence of rigid connections, localized stress concentrations caused by thermal expansion and load cycling during kiln operation, and hence the risk of cracks and fractures in the entire arrangement, can be largely prevented.
