Patent ES-412236-A1 (ES)
Title: Convection drier with a travelling bed
IPC: F26B17/12
Filed: 1973-03-02
Abstract: A convection drier with a travelling bed is provided for drying and heating bulk materials such as coal, quick coke, blast furnace slag etc. The fundamental principle of its operation consists in blowing through a layer of dried material which is continuously travelling. A stream of a drying agent/hot air or combustion gases/ is passed through a bed of dried material blowing upon the particular particles of this material and removing moisture therefrom. Owing to the fact that the drying agent is passed in variable directions, a good turbulence of air flow as well as a high heat exchange can be obtained. The dried bed is passed between two perforated walls by means of a chain conveyor or falls sliding down by itself due to the force of gravity. The overall dimensions of the drier of the invention are far smaller than those ones of conventional driers. The drier can be adapted to drying bulk materials in large quantities and requires only small power supplies. The gas/even polluted combustion gases/ used in the drying process is preliminary cleaned in the drier for further use.

Title: Pneumatic tyres
IPC: B60C9/18
Filed: 1977-01-21
Abstract: A conventional tyre carcass with a radial reinforcement inlay (15, 16) in the crown area of the radial tyre is provided with an additional reinforcement material layer (20, 21) comprising a flexible sheet-like structure with quadratic or rhombic bonding without a calendered-on rubber coating.

Title: Modular tubular solar energy collector apparatus
IPC: F24S10/70
Filed: 1978-02-09
Abstract: The disclosure relates to a modular form of solar energy collector apparatus in which several double-wall glass tube collectors, each with vacuum jacket, depend from opposite sides of an elongated manifold. The manifold includes split halves of foamed polymer insulation and rigid fiberglass reinforced skin thereon, assembled about closed-looped, serpentine liquid carrying tubes preferably of metal or glass in U-tube configurations depending from the manifold halves and extending into the larger double-walled glass tubes, the serpentine tube being connected, respectively, into inlet and outlet header pipes. The interior chamber of the collector tubes is closed by the manifold, thereby enclosing a part of each U-tube branch of the serpentine in a non-turbulent air space. Solar energy collected on the absorber surface of the inner glass tube wall is transmitted to the U-tube and liquid therein. The U-tube within the collectors is blackened and non-reflecting. Principal heat transfer from absorber to U-tube is by radiation with some conduction and convection transfer. The heat transfer liquid is entirely within a closed circuit, which avoids leaks, reduces weight, and cycle time of the liquid is reduced to a fraction of other liquid systems.
