Title: Fuel system for compression ignition engine
IPC: F02M63/00
Filed: 1981-07-03
Abstract: A fuel system for a compression ignition engine comprises a plurality of injection nozzles controlled by electromagnetic devices to deliver fuel in timed relationship to an engine. Fuel for the nozzles is stored under pressure in accumulators which are charged from a source of fuel through small bore pipes so that the recharging of the accumulators after fuel delivery is delayed.

The signals provided by the transducers register a pressure drop when fuel flows through the nozzles and the fall in pressure is related to the quantity of fuel supplied through the nozzle.
Patent ES-8304281-A1 (ES)
Title: Power transmission unit with infinite speeds.
IPC: F16H29/20
Filed: 1982-02-17
Abstract: A rotor of the transmission is journaled within a stationary housing and is driven by rotatable gear rack components therein. A pinion gear drives the gear rack components by sequentially meshing with spaced apart gear racks on each component. A speed selector assembly positions the pinion gear relative the rotor axis and includes a gear train to couple the gear to a power input shaft. Speed changes between the input shaft and a rotor driven output shaft are effected by positioning of the pinion gear away from the rotor axis resulting in the gear rack components moving eccentrically within the rotor. A cam structure acts on each gear rack component to control meshing of the gear racks on the component with the pinion gear. Each of the pairs of gear racks on a modified form of the transmission are resiliently mounted on their respective gear rack assemblies. Rails of each gear rack assembly rotate about stationary but adjustable cam rings of the transmission. The gear rack assemblies include bearing elements at their ends for engagement with the transmission rotor.

Patent ES-8303625-A1 (ES)
Title: Electrohydraulic three-port, two position valve
IPC: F16K11/07
Filed: 1982-03-23
Abstract: A three-port, two-position electrohydraulic valve has an elongated valve member reciprocatably guided in a bore of the valve housing only by two sealing rings of small friction and including only two further sealing rings cooperating with sealing edges respectively provided on the valve member and the housing for controlling fluid flow between the three ports. The valve member is reciprocated between two end positions against the force of a return spring by an electromagnet. Such a valve requires only small forces for reciprocation of its elongated valve member, so that a small electromagnet is sufficient. The valve of the present invention favorably differs from known electrohydraulic three-port, two-position valves which are constructed as seat valves and operated in opening direction by an electromagnet of long stroke and which require also considerable forces during operation, due to large friction forces inherent with seat valves.
Patent ES-8302532-A1 (ES)
Title: Method and apparatus for accurately positioning a bead bundle.
IPC: B29D30/32
Filed: 1982-03-24
Abstract: A bead bundle positioning mechanism is provided to accurately locate one axial surface of each bead bundle prior to radial expansion of the tire carcass. Each bundle (62) is held by a plurality of circumferentially spaced clamping mechanisms (10) each of which has a pair of clamping elements (40,48) respectively engaging the axially inner (68) and axially outer (72) surfaces of the bead bundle (62). The axially inner surface (68) of each bead bundle (62) is located by respective clamp members (40,48) which are adapted to cooperate with a tire building machine to provide a predetermined axial distance between the bead bundles during tire assembly while also maintaining the inner axial surfaces in parallel planes which are normal to the longitudinal axis (15) of the tire building drum (74). The inner and outer clamping elements (40,48) are actuated by independent fluid motors (34,36). The clamping force exerted by the axially inner clamping element (40) is greater than the clamping force exerted by the axially outer clamping element (48), to insure that the axially inner surface (68) of the bead bundle (62) is the referenced positioning surface. The inner clamping element (40) interacts with a stop member (42) to establish a predetermined position for the axially inner surface (68) of the bead bundle (62).

Title: Motion detectors.
IPC: G08B13/16
Filed: 1983-08-05
Abstract: A constant range ultrasonic motion detector features an ambient atmospheric condition sensor which senses the temperature, pressure, and percent relative humidity of the ambient atmosphere and produces therefrom a range compensation signal to adjust the sensitivity of the ultrasonic motion detector for stabilizing the range. The range compensation signal is applied to adapt detector amplifier gain and/or threshold level to the variation between design and ambient conditions. In one embodiment, an analog summing network at the ambient atmospheric sensor outputs provides the range compensation signal and in a second embodiment a microprocessor is operative to provide the range compensation signal.

Title: Method and apparatus for preventing inadvertent criticality in a nuclear fueled electric powering generating unit.
IPC: G21C17/00
Filed: 1983-08-10
Abstract: An inadvertent approach to criticality in a nuclear fueled electric power generating unit is detected and an alarm is generated through on-line monitoring of the neutron flux. The difficulties of accurately measuring the low levels of neutron flux in a subcritical reactor are overcome by the use of a microcomputer which continuously generates average flux count rate signals for incremental time periods from thousands of samples taken during each such period and which serially stores the average flux count rate signals for a preselected time interval. At the end of each incremental time period, the microcomputer compares the latest average flux count rate signal with the oldest, and preferably each of the intervening stored values, and if it exceeds any of them by at least a preselected multiplication factor, an alarm is generated. The interval and multiplication factor are chosen such that an alarm is generated early enough in the event to provide adequate time for an automatic system or the operator to take action which prevents the reactor from going critical yet minimizes the likelihood of a spurious response. As applied to a pressurized water reactor system, boron dilution events are detected in time that the chemical and volume control system can be isolated and the valves for the refueling water storage tank can be opened to inject highly borated water into the reactor coolant system to keep the reactor subcritical.
