Title: Acyl derivatives of clavulanic acid methods for their preparation and compositions containing them
IPC: C07D503/00
Filed: 1975-10-21
Abstract: Compounds of formula III < IMAGE > wherein COR<2> is an acyl radical of a carboxylic acid and R<8> is hydrogen, an organic radical or a cation of a pharmaceutically tolerated salt are prepared by reacting a carboxylic acid of formula R<2>-CO2-H (V> or its reactive functional acylating derivative with a compound corresponding to formula III but containing a hydrogen atom instead of COR<2>. Uses of the process according to the invention are directed to the removal of a radical R<8> cleavable by hydrogenation, and to the hydrogenation of the group -CH2OC-OR<2> to give a CH3 group. The compounds prepared find pharmacological applications since they inhibit beta -lactamase. They are also suitable for use as intermediates for the preparation of other pharmacologically useful substances.

Patent ES-449276-A1 (ES)
Title: Self-checking read and write circuit
IPC: G06F11/267
Filed: 1976-06-26
Abstract: A self-checking read and write circuit interfaces a control circuit with a plurality of peripheral circuits. The read and write circuit receives address and data commands from the control circuit, decodes the commands and produces a driving signal to operate relays in the peripheral circuits. The read and write circuit also receives inputs from the peripheral circuits indicating the state thereof, multiplexes and inputs and forwards them to the control circuit under control of address signals. The circuit is self-checking in that a readout multiplexor which scans for state changes in the peripheral circuits has its even parity inputs connected at the outputs of the drive signal decoder and its odd parity inputs connected to the scanned points. A parity check circuit on the multiplexor address leads determines whether the address has even or odd parity. If the parity is even, the output of the multiplexor is compared to the output of the drive signal decoder. If the parity on the address leads is odd, the output of the multiplexor is forwarded to the processor. A single hardware failure in the multiplexor address circuitry causes a failure in one of several modes involving a shift in parity values. These failure modes are detected when the output of the multiplexor is compared to the output of the drive signal decoder.

Patent ES-8205948-A1 (ES)
Title: Fuel injection pumping apparatus
IPC: F02D1/02
Filed: 1981-09-09
Abstract: A fuel injection pumping apparatus for supplying fuel to an internal combustion engine comprises an injection pump to which fuel is supplied by a low pressure pump. A part of the injection pump defines a surface against which a control pressure can act to vary the amount of fuel supplied by the injection pump, the part being spring loaded by a spring in a direction to oppose the force exerted by the control pressure and to increase the amount of fuel supplied. The control pressure is derived from the low pressure pump by means of a control system and if the output pressure of the low pressure pump should fall due to for example fuel starvation, the part will move in the direction to increase the amount of fuel supplied by the apparatus, this being permitted even though the output pressure is reduced. In order to avoid an increase in the amount of fuel supplied a pressure responsive valve is provided which is responsive to the output pressure of the low pressure pump and which closes to prevent fuel flow to the injection pump when the pressure falls below a predetermined value.
