Title: Portland cement manufacture
IPC: C04B7/43
Filed: 1977-01-19
Abstract: Waste matter is incinerated in a combustion zone external to a rotary cement kiln. The resulting gaseous product is taken up in effluent gas from the cement making process in contact with calcareous material.

Patent ES-470719-A1 (ES)
Title: Fuel pump device
IPC: F04B1/113
Filed: 1978-06-12
Abstract: The pump has a rotor with a diametrical bore in which two pistons reciprocate radially. A longitudinal bore between them forms the pumping chamber and had radial bores connecting with the inlet and discharge passages. The outer ends of the pistons have shoes which carry rollers which run on a cam on the inside of the casing. This produces the reciprocating action. The cam has a cam profile with a stop ring on the inside of it. The stop ring (32) is formed of a series of separate circumferential sections (34). The sections are joined by flexible pieces (36). This enables the sections to move radially inwards as the cam profle is rotated to vary the stroke in a reliable manner.

Title: A Current Regulator Circuit, in Particular for Charging an Emergency Power Supply Unit at Constant Current
IPC: H02J7/02
Filed: 1979-11-19
Abstract: A circuit for charging a storage battery (10) at constant current by means of a transformer (T) whose primary winding (12) is connected to an AC mains (11) and whose secondary winding (13) feeds a rectifier bridge (14). The storage battery is connected, at the output of the rectifier bridge, in series with a resistor (15) and a light bulb (16). A transistor (18) has its emitter-collector circuit connected in series with a resistor (19) and this series connection is connected in parallel with the light bulb (11). The transistor base is biased by a voltage divider chain (20, 21) connected between one pole of the battery and the output of the rectifier bridge. While the bulb is in order it acts both as a pilot lamp and as a regulator device to ensure substantially constant current charging of the battery. The transistor is then off. If the bulb filament breaks, the transistor is biassed to become conductor to maintain adequate charging current through the battery.

Title: Handling device mounted on a vehicle to carry out the handling of loads such as skips and containers
IPC: B60P1/64
Filed: 1980-06-14
Abstract: The device comprises a derrick with a main telescopic arm and an auxiliary arm. The telescopic arm 9 is pivoted on a sub-frame which in turn is pivoted to the main chassis of the vehicle.

Patent ES-8106625-A1 (ES)
Title: Mechanically multistable liquid crystal cell
IPC: G02F1/139
Filed: 1980-11-28
Abstract: A liquid crystal cell having memory is provided by disposing a liquid crystal material having nematic directors between two substrates which are fabricated to contain an array of singular points. The cell may further include means for detaching singularities such as appropriate electrode arrangements. These substrate configurations provide multistable configurations of the director alignments because disclinations must be moved, either through the bulk of the liquid crystal material or on the substrate surfaces to switch between the stable configurations. The switching of the device between stable configurations may be accomplished by the application of electrical fields to the liquid crystal material. The stable configurations may be optically differentiated by the incorporation of pleochroic dyes into the liquid crystal material or by crossed polarizers.

Patent ES-8406299-A1 (ES)
Title: Document sheet feeding and registration apparatus and method.
IPC: B65H9/06
Filed: 1983-07-29
Abstract: A document sheet feeding and registration apparatus and method is described for deskewing and registering a document sheet (7) relative to a registered copying position on a copier platen (3) by feeding it against a sheet aligning document registration stop (18). Initially the document sheet is fed towards the registration stop (18) with a first document sheet feeder (17) exemplified by a widely transversely spaced pair of high friction sheet feeding rollers, which resist skewing of the document sheet. Then the first document sheet feeder (17) is removed from the document sheet (7) after its lead edge is engaged by a second document sheet feeder (16) and before the document sheet (7) engages the registration edge stop (18) so that final skewing control of the document sheet is only by the second document sheet feeder (16). The second document sheet feeder (16) is a single sheet feeding roller positioned centrally of the document sheet lead edge area and positioned closely adjacent the registration edge (18). This single roller provides a brief low rotational resistance deskewing of the document sheet (7) while driving the document sheet into final alignment with the registration stop (18). All of the sheet feeding rollers are positioned over the document on the platen extending through a backing plate (27) so as to be hidden during copying.
