Title: Guide rail arrangement for vehicle seats
IPC: B60N2/06
Filed: 1975-02-13
Abstract: An improved guide rail arrangement especially adaptable for vehicle power seats includes a pair of interleavable guide rail assemblies that are individually bolted to the vehicle seat and to the vehicle floor. The fixed guide rail assembly includes a C-shaped member extending upwardly into a guiding space that is formed between the parallel, downwardly projecting legs of a pair of U-shaped rail elements forming the movable rail assembly. A plurality of spaced, horizontally disposed alignable apertures are respectively incorporated in adjacent legs on one transverse side of the interleaved guide rail assemblies. Horizontal movement of the movable rail assembly with respect to the stationary assembly is stopped in a novel way by incorporating a pair of blocking plates symmetrically supported on transversely opposite sides of the longitudinal axis of rail movement. Each blocking element has at least one outwardly directed projection which is normally seated in an aperture in the leg of the inner rail element of the movable guide rail assembly, and is movable transversely outward through the apertures in the legs of the remaining guide rail elements when aligned to lock the vehicle seat with respect to the floor. Such movement is effected by means of a camming arrangement including a longitudinally positionable plate mounted adjacent the blocking plates in the interior of the inner rail element.

Title: Drive mechanism for displacing window panes, sliding roofs and the like of motor vehicles.
IPC: E05F15/697
Filed: 1979-12-13
Abstract: A drive mechanism serving for displacing window panes, sliding roofs and the like of motor vehicles is provided. The drive mechanism comprises a drive motor with an output shaft which drives the worm shaft (10) of a worm gear. The worm wheel (12) of the worm gear forms a first clutch half mounted freely rotatably and having on the end face receptacles for dogs (28) which belong to a second clutch half. The second clutch half is connected firmly to the output shaft (18) of the worm gear. The dogs (28) project from the second clutch half in the axial direction of the output shaft (18). Arranged coaxially relative to the axis of rotation of the worm wheel (12) within a housing (14) surrounding the worm gear is a cylindrical wall (34) which is fixed to the frame and against which a helical spring bears with slight prestress. The ends of the spring wire (42) are directed radially away from the wall and form extensions which interact with shoulders of the worm wheel (12) and with stops of the second clutch half (48) respectively. The shoulders and the stops engage on the extensions (42) on the opposite sides in each case. When the force flux comes from the worm wheel, the spring is released from the wall and the mechanism can operate. But when the force flux arrives at the second clutch half from the output shaft, the spring is braked against the wall, so that a movement of the mechanism is not possible from the part to be displaced.

Title: Load carrying device
IPC: B60P1/64
Filed: 1980-02-29
Abstract: An improved movable load carrying device for vehicles with cargo space is disclosed. Such load carrying devices render possible loading and unloading operations from three sides and with suitable working positions of the operator, but on the other hand it was found, that the inward as well as the outward movement of known load carrying devices into and, respectively, out of the cargo space of a vehicle are troublesome and require relatively great exertion and often even heavy lifting, which to some extent takes away the advantages with respect to loading and unloading. In order to eliminate these and other disadvantages, according to the present invention a movable load carrying device is proposed the load table of which is formed on its lower surface with guide grooves for a pair of carrying rollers. The carrying rollers are mounted in the rear portion of the cargo space and capable together with the wheels of the support legs to movably support the load table as long as the center of gravity of the load table is located outside the carrying rollers, and together with rollers provided at the forward portion of the load table, seen in the inward movement direction, to movably support the load table as long as the center of gravity of the table is located inside the carrying rollers.

Patent ES-8105898-A1 (ES)
Title: Shootthrough fault protection system for a voltage source transistor inverter
IPC: H02H3/44
Filed: 1980-09-18
Abstract: Faulted transistors in a voltage source transistor inverter are protected against shootthrough fault current, from the filter capacitor of the d-c voltage source which drives the inverter over a d-c bus, by interposing a small choke in series with the filter capacitor to limit the rate of rise of that fault current. At the same time and in response to a shootthrough fault, a pre-charged capacitor, included in a crowbar circuit connected across the d-c bus, discharges through the faulted transistors in a direction opposite to the fault current in order to effect fast turn-off of the transistors, thereby preventing damage thereto.
Patent ES-8200980-A1 (ES)
Title: Method and apparatus for ciphered transmission of information.
IPC: H04L9/06
Filed: 1980-10-06
Abstract: The information to be processed and to be transmitted is formed by information signal blocks (1-12) which are separated from one another by separating signals. The information signal blocks (1-12) are of equal length and are in each case formed by five ''O'' or ''L'' signals. The encoding at the transmitting end is effected by interchanging the information signal blocks (1-12) in their sequence in time. To prevent or at least greatly impede an intrusion into the encoding system, information signal blocks (4, 6, 10) of a given information content are replaced before the transmission. The information signal blocks (4, 6, 10) consisting, for example, only of ''O'' signals (a) are substituted by substitution signal blocks (4', 6', 10') which are generated in a quasi-random signal sequence at the transmitting end. The substitution signal blocks are recognised by comparison at the receiving end and replaced by information signal blocks generated at the receiving end which correspond to the information signal blocks (4, 6, 10) substituted at the transmitting end.

Patent ES-8304356-A1 (ES)
Title: Power capacitor structure and method of assembly.
IPC: H01G4/32
Filed: 1981-12-11
Abstract: A power capacitor and method of making it employs the technique of stacking capacitor sections together in an enclosure of which each section includes rolled electrode foils and dielectric layers of which at least one of the electrodes has a rolled edge resulting in a greater thickness in that portion of the section. In order to permit thorough impregnation of the section, the winding tension is deliberately made loose and the initially resulting section is insufficiently tight to retain conductive tabs reliably in contact with the foil electrodes. The stacked sections have, however, between them in the body portion intermediate the rolled edges, one or more sheets of material that compress the body portion and insure reliable pressure contact thereat while not interfering with the impregnation of the fluid throughout the section.
