Title: Dual voltage X-ray switching system.
IPC: A61B6/03
Filed: 1981-11-17
Abstract: X-ray pulses at two different photon energy levels are produced with an x-ray tube that has an adjustable resistor element in a circuit that connects the anode and filament of the tube to a high voltage supply. Two bias voltage supplies are connected in additive fashion between a control grid element of the tube and its filament to enable control of voltage drop and current through the tube. Switch means are provided to selectively shunt either or both bias voltage supplies in a repeatable order to thereby alter the bias voltage on the control grid and enable producing x-ray pulses having energies corresponding with the voltage drop and current through the tube at a selected bias voltage in accordance with the load line on the anode characteristic curve plot of the tube as determined by the value of the adjustable resistor element.

Patent ES-8306532-A1 (ES)
Title: Regenerative preheater for two separate gas streams
IPC: F28D19/04
Filed: 1982-10-08
Abstract: A regenerative air preheater has a heat-exchange sector plate centered on an axis and formed with a multiplicity of axially throughgoing passages with intake and output heating-gas hoods axially flanking the plate and conduits for passing a heating gas from the intake hood through the plate to the output hood for heating the plate. Intake and output secondary heated-gas hoods each within one of the heating-gas hoods and axially flanking the plate are axially aligned with each other and only cover a portion of the plate. Thus the heating gas can pass through the plate only around the plate portion covered by the secondary hoods. Intake and output primary heated-gas hoods within the respective secondary hoods and axially flanking the plate are axially aligned with each other and only cover a subportion of the plate portion covered by the secondary hoods. Thus the secondary gas will be heated at regions of the plate portion not covered by the primary hoods. A drive rotates the secondary hoods synchronously with each other about the axis in a predetermined rotational sense. Thus the heating gas will heat regions of the plate not covered by the secondary hoods so that when same move into alignment with these heated regions the secondary gas stream will be heated. Portions of the primary hoods can be displaced nonaxially within the respective secondary hoods and to vary the heat-exchange between the primary stream and the plate.

Patent ES-8404123-A1 (ES)
Title: A.C. motor controller.
IPC: H02P23/00
Filed: 1983-04-15
Abstract: An energy conserving motor controller for starting and operating A.C. induction motors at high efficiency. This invention provides a power controller for an A.C. induction motor (4) comprising switching means (1, 2, 3) which control the alternating currents supplied to the motor (4), and control means (5) which control the non-conduction angle of the motor (4) according to control voltages from either the efficiency monitors (6) or soft start control (7). The efficiency monitor (6) monitors the voltage generated by the motor (4) during the non-conduction of the switching means (1, 2, 3). If that voltage is less than a reference, the non-conduction angle is reduced whereas if the voltage is greater than the reference, the non-conduction angle is increased. For motors operating at less than full load efficiency, the voltage and consequently the iron losses are reduced. The soft start control (7) causes the initial non-conduction angle to equal a present angle, and decrease slowly to zero thereby reducing the start voltage and hence start current and torque supplied to the motor (4).

Patent ES-8504448-A1 (ES)
Title: Functional agglomerated speckles and dentifrices containing them
IPC: B01F23/57
Filed: 1983-12-30
Abstract: Functional agglomerated speckles, for incorporation in dentifrices, include agglomerates of a water insoluble powdered functional material and water insoluble, ethanol soluble ethyl cellulose, and may sometimes preferably also include a water soluble binder, such as polyvinyl pyrrolidone. Such speckles satisfactorily maintain their integrity and identity during processing of the dentifrice after addition of the speckles to a main dentifrice body but on storage, after packaging of the dentifrice in dispensing tubes, soften sufficiently so as to become essentially impalpable to one utilizing the dentifrice in brushing his teeth. Despite such softening the speckles continue to maintain their identity as speckles in the dentifrice. The speckles are especially useful in translucent or transparent gel dentifrices which contain components, such as flavouring and surface active agents, which may controllably soften the speckles on storage.
