Patent ES-455141-A1 (ES)
Title: Pressure-sensitive copying paper
IPC: B41M5/155
Filed: 1977-01-18
Abstract: A method of producing self-contained pressure-sensitive copying material having a coating which contains both a particulate mineral color-developing material and microcapsules enclosing a solution of a colorless color former which is reactive with the color developing material to produce a colored product, in which the particles of color developing material (e.g. an acidic clay) and optionally the microcapsules as well, are treated with a protective agent to inhibit premature color development. The protective agent may be a self-crosslinkable polymer, such as an aminoplast polymer (e.g. a urea-formaldehyde or melamine-formaldehyde polymer), or a epichlorohydrin polymer (e.g. an aminoepichlorohydrin or an amide/aminoepichlorohydrin polymer), or an anionic surfactant (e.g. a lauryl sulphate salt or a sulphonated ricinoleic acid derivative, a dodecyl benzene sulphonate salt, or a dibutyl or dioctyl ester of sulphosuccinic acid), or a fluorine-containing paper sizing agent, or a non-self-crosslinkable polymer which is a wet-strength agent for paper (e.g. a polyethylene imine resin).

Patent ES-8205958-A1 (ES)
Title: Rotary compressor.
IPC: F04C18/22
Filed: 1981-02-13
Abstract: A rotary air compressor includes a rotor which rotates within a housing and controls communication through inlet and outlet ports provided on the housing and compresses air communicated through the inlet port for delivery to the outlet port. The inlet and outlet ports are provided with check valves controlling communication therethrough. After the rotor rotates through a dead-center position, the check valves in both the inlet and outlet ports are closed. The rotor then rotates into a position in which the apex seals carried by the rotor wipe across the inlet and outlet ports simultaneously, thereby opening a communication path bypassing the apex seals so that the pressure levels in the chambers across the rotor are equalized. As the rotor continues to rotate, air is compressed and communicated to the outlet port.

Patent ES-8204231-A1 (ES)
Title: Battery filling system.
IPC: H01M50/618
Filed: 1981-06-02
Abstract: A level-sensitive filling device for fitting to a secondary electrical cell is formed as a plug (20) to replace the normal vent plug. The device includes inlet and outlet passages (1 and 2) respectively for connection to a water supply system and is controlled by a float (4) which, in use, is supported by the electrolyte (5) of the cell. The float (4) and the structure of the device around the openings (22 and 23) to the inlet and outlet passages are shaped to co-operate in such a way that when the correct level of electrolyte (5) is reached, the inlet and outlet passages (1 and 2) are substantially closed off from the body of the cell but not from one another. The shaping is such that the path of flow (6) from the inlet opening (22) to the outlet opening (23) is of reduced cross section in relation to the inlet and outlet passages (1 and 2) and the resultant flow of fluid from one passage (22) to the other passage (23) thus causes a reduction of pressure outside the closure (7) formed by the float (4) in relation to the pressure in the cell, this differential pressure preventing any further flow of water into the cell, but allowing the escape of gas generated in the cell.
