Patent ES-464691-A1 (ES)
Title: Dishwasher with effective cleaning action even with clogged filter - has by=pass pipe for circulating water when pump action declines
IPC: A47L15/42
Filed: 1977-12-02
Abstract: The filter system for dishwashers includes a filter mesh (6) mounted between the crockery and the water sump and covers a drainage chute (4) and also includes a bypass pipe (15) which leads from the wash container (1) to the recirculating pipe (12). The inlet opening (16) to this bypass pipe (15) is mounted in the wash container (1) above the water (13) set when the circulating pump (3) is in operation but below the water levl (14) when the pump is stationary. The bypass pipe is inactive during normal pumping action and only becomes active when the pump output falls and the water in the container rises which is caused when the filter clogs up. The circulating pump then draws in water from the wash container via the bypass.

Patent ES-477067-A1 (ES)
Title: Apparatus for making filter elements for gas or liquid
IPC: B01D29/11
Filed: 1979-01-23
Abstract: Tubular filter elements are formed by first feeding a slurry into a tubular moulding space between a vertical core and a cylindrical fine mesh screen. Air pressure is applied to the slurry so that the liquid drains through the screen and through a screen at one base of the space, while a mass of microfibres builds up to be removed from the space for bonding by a synthetic resin. A reciprocable sleeve increases the effective height of the screen as the mass builds up. Layers of microfibres having different qualities can be assembled by using different core diameters in succession. Filter elements that need not necessarily be cylindrical can be formed by this or analogous pressure methods in which the majority of the microfibres are directed approximately parallel to one another, and/or in which one or each face of the filter element has moulded into it a perforated sheet of supporting material.

Title: Method of controlling reciprocating four-stroke internal combustion engines
IPC: F02D21/08
Filed: 1984-02-02
Abstract: The present invention relates to a method for unthrottled load control of an internal combustion engine by means of exhaust gas.
