Title: 7-(alpha-(2-oxo-imidazolidin-1-yl-carbonylamino)-phenylacetamido)-cephalosporins processes for their preparation and their use as medicaments
IPC: A23K20/195
Filed: 1976-10-27
Abstract: Novel cephalosporins of the formula < IMAGE > in which R1 represents hydrogen, alkyl or acyl and R2 represents hydrogen, alkyl or aryl and which can be present with respect to the centre of chirality C* in the two possible configurations R and S and as mixtures of the diastereomers resulting therefrom, and their non-toxic, pharmaceutically tolerable salts are prepared.

Patent ES-463874-A1 (ES)
Title: Pressure modulating valves for braking systems
IPC: B60T11/10
Filed: 1977-11-04
Abstract: A dual pressure modulating valve unit for a motor vehicle braking system has two identical valves arranged side-by-side in a common housing, each valve being for inclusion in separate sub-systems of a split braking system. The valves are of the pressure limiting or pressure reducing type wherein the pressure at which the valves start to reduce or limit the outlet pressure is determined by a biassing load on the valve plungers. The biassing loads are provided by a beam which normally divides the load of a single biassing spring equally between each plunger. In the event of a failure in one sub-system the plunger of the valve in the other sub-system receives the full load of the spring so that the pressure at which that valve starts to limit or reduce is substantially increased.

Patent ES-8201483-A1 (ES)
Title: Anti-locking mechanism
IPC: B60T8/54
Filed: 1980-04-01
Abstract: An anti-locking mechanism includes an assembly attached to move with a wheel of a vehicle. The assembly includes a spring biased inertia wheel movably mounted to a manifold.
