Patent ES-8405568-A1 (ES)
Title: Digital transmission systems.
IPC: H04J3/06
Filed: 1983-08-24
Abstract: An aligner with a time switching capability is disclosed. The aligner has a store for storing incoming data. The store is sufficiently large that it can hold more than one frame of information. Data is written into the store under the control of clock signals associated with the incoming data. Data is read from the store under the control of a local clock. Read addresses are generated by a unit which is so arranged that if a clash between the current write address and the generated read address is sensed to be imminent, reading of the corresponding address in the previous or subsequent frame occurs. Thus, the aligner can operate as a time switch and clashes between reading and writing are avoided by allowing slippage of one frame.
Patent ES-8504509-A1 (ES)
Title: Cut and clench device, and method
IPC: A47C27/07
Filed: 1984-02-16
Abstract: A device for cutting a helically wound wire (40) and forming a loop at the cut end, comprises a guiding-positioning member (96) for restraining relative movement of the helical for cutting and forming a loop on the end of the helical, and shearing-clenching member (88) movable relative to the guiding-positioning member between a rest position and cutting and clenching positions. When moved from the rest position (Fig. 7a) to the cutting position (Fig. 7b), a first shearing surface 140 on the shearing-clenching member and a mating second shearing surface 129 on a cutting channel 128 of the guiding-positioning member cooperate to shear the helical. As the shearing-clenching member continues in a single motion between the cutting and clenching positions, an abutment surface 138 on the shearing-clenching member engages one of the sheared ends of the helical and cooperates with an edge 170 on a retaining channel 126 of the member 96 to form a residual loop (Figs. 7c, 7d). The device and method are particularly suited for the automated cutting and finishing of helicals in the manufacture of bedspring assemblies.

Title: Vehicle spring suspension arrangement.
IPC: B62D61/12
Filed: 1984-02-17
Abstract: A vehicle such as a 6x2 tractor having at least three axles is provided with a novel leaf spring suspension (1) for its middle axle. When the load, imposed on the chassis by a semi-trailer, exceeds a predetermined threshold, the free, rear, end of the leaf spring (1) engages the under-surface of the upper portion of a slipper bracket (4) attached to the chassis, and the middle axle takes a proportion of the load. With loads below the threshold, the free end drops through a vertical "air gap" and is held by a lower supporting arm on the slipper bracket, the middle axle being unloaded. The rear, driving, axle is thus more heavily loaded whenever the vehicle is part-laden, ensuring greater traction.
