Patent ES-465011-A1 (ES)
Title: Control system for variable pitch axial fan for utility boiler
IPC: F04D27/00
Filed: 1977-12-13
Abstract: The disclosed system detects the pressure rise across the fan and the flow rate in the system and integrates signals corresponding thereto, and outputs a signal to indicate to the user when the pressure rise exceeds a given level for a corresponding flow rate to warn of a condition within a given degree of a stall condition. The system outputs another signal to block any increase in fan blade pitch and substitutes a decrease pitch signal in response to a predetermined closer approach to a stall condition so that the pitch of the blades is reduced to a position in which the pressure rate rise and flow rate are reduced to a safe level with respect to a stall condition. The system also includes means responsive to the predetermined closer approach to stall to prevent the user from feeding a blade pitch increase signal following a reduction in the pressure rise across the fan until the user resets a bistable device.

Title: Press for extracting juice from fruit - involving horizontal convergence of porous walls for press vol. redn. without loss of filtration area
IPC: C12G1/00
Filed: 1980-11-27
Abstract: A press for extracting juice from fruit, e.g. grapes, comprises a chamber with porous walls comprising a series of articulated panels which can be closed up face to face by convergence of the walls along a horizontal axis. The sidewall crests may be moved together by use of an array of lead source linking opposing hinge zones, or by other means, e.g. external opposed thrust rams. The articulated joints may be sealed by strips of flexible inert material. Compared with cylindrical presses involving a coaxially travelling ram, the compressive motion does not reduce the surface area available for juice extraction as the press volume is reduced nor tend to flatten any drainage channels generated through the bulk of material by the outflow.

Title: Method of thermally processing foodstuffs, hermetically sealed foodstuffs containers and thermally processed foodstuffs.
IPC: A23L3/34
Filed: 1986-01-28
Abstract: Low acid heat-sensitive foodstuffs, such as low acid heat-sensitive vegetables and cereal grain products, are thermally processed in the presence of a mixture of an acid and its lactones, preferably an aldonic acid with its lactones, the acid of which makes possible a condiderably reduced commercial sterilizing parameter (i.e. lower temperature and/or time) whereby more of the flavor, color, or texture of the foodstuff is retained, and is closer to that of the freshly harvested home-cooked product, compared to the foodstuff processed at a more severe parameter when the acid is not employed. The type and level of the acid employed and its presence with its lactones results in a thermally processed foodstuff which does not have an objectionable acid taste. The preferred mixture is gluconic acid with its lactones, glucono-delta lactone and glucono-gamma lactone, provided to the foodstuff by combining it with a precursor of gluconic acid, preferably glucono-delta lactone.
