Patent ES-8201928-A1 (ES)
Title: Pneumatic device for flour-transport.
IPC: B65G53/60
Filed: 1981-03-18
Abstract: The method and plant for adjusting the transport conditions in a pneumatic conveyor conduit (7) provided with a fan may be applied particularly when the whole air conveyor plant has a flat pressure-volume characteristic. The main problem during the adjustment of such plants is the fact that the transport power of such flour-mills is subjected to important fluctuations, which give rise to adjustment difficulties, particularly when a plurality of conveyor conduits are joined together into a common manifold. According to the method, the pressure differential is measured between the inlet (8) and the outlet (11) of a cyclone (2) arranged in the conduit (7) and a valve (13) associated to the outlet (11) of the cyclone (2) is regulated automatically as a function of the pressure differential measured and with a view to obtaining a desired value for this pressure differential. Hence, the power required may be reduced substantially and with simple means since the pneumatic transport is effected in more stabilized conditions. The pneumatic flour-milling plant comprises a cyclone (2) as separator (1) cooperating with a measurement device (25) for the pressure differential and an air valve (13) controlled by such measurement device (25).

Filed: 1981-05-11
Abstract: A transport device for a sewing machine having a housing, a feeder foot and a fabric presser foot, a drive mechanism for driving the feeder foot and the presser foot, a transmission operatively interconnecting the presser foot and the feeder foot to the drive mechanism for alternately reciprocating the feeder foot and the presser foot relative to each other in up and down motions directed perpendicular to a stitch plate of the sewing machine, comprises linkages which cause the feeder foot and the presser foot, during their up and down motion, to move at a speed approaching zero during a touchdown phase of the motion. The transmission includes an eccentric connected to the drive mechanism which oscillates at a selected frequency. A triangular lever is connected to the feeder foot and the presser foot. A coupling member is connected to the eccentric and to the linkages with a link of the linkages pivotally mounted to the sewing machine housing and interconnecting the coupling member with the triangular lever. The transmission also includes a steering arm mechanism for providing a variable transmission ratio between the eccentric and the coupling member. A further linkage transmission connected to the drive mechanism varies the transmission ratio of the steering mechanism, the linkage transmission operating at twice the frequency of the steering mechanism.
Patent ES-8204560-A1 (ES)
Title: Electronic circuit for Geiger-Müller gamma-ray detectors.
IPC: G01T1/18
Filed: 1981-08-06
Abstract: A method and apparatus are described for reducing the "dead-time" of a Geiger-Müller tube to about 5 or 6 microseconds in which the initial fall in anode voltage of the tube caused by a gamma-ray photon penetrating its wall and ionising the gas in the tube is amplified and the amplified signal used to switch the anode voltage to a lower value, thereby inhibiting further ionisation of the gas in the Geiger-Müller tube. After a short period of time in the range 3 to 10 microseconds, preferably 5 to 6 microseconds, the anode voltage is switched back to the original relatively higher voltage.
Patent ES-8302466-A1 (ES)
Title: Anaesthetic vaporiser.
IPC: A61M16/01
Filed: 1981-09-08
Abstract: An anaesthetic vaporizer of the by-pass type has a sump 7 with an outlet flow path comprising a first run 27 leading upwardly, a second run 30 leading downwardly and a third run 32 leading upwardly again. A duct 23 connects the lower end of the run 30 with the lower part of the sump and in normal operation is sealed by the sump liquid. However, if the vaporizer is displaced such that the liquid flows from the sump into runs 27 or 30 of the outlet flow path the liquid inevitably drains from the duct 23. A flow path for inflowing gas is thereby opened directly to the downstream end of the run 30, preventing the over-administration of vapor from the device and removing any danger of liquid anaesthetic being blown through the device from the runs 27 and 30.

Patent ES-8402479-A1 (ES)
Title: Demodulator arrangement for signals which are frequency-modulated on a carrier wave.
IPC: H03G3/20
Filed: 1983-01-25
Abstract: A demodulator of the type employed in a "zero-IF" system uses a local oscillator for providing guadrature output signals at the center frequency of an FM signal to be demodulated. The demodulator has first and second mixers for separately mixing the FM signal with the quadrature signals to provide a first and second output signal each in quadrature at the outputs of said mixers. These signals are low pass filtered. The demodulator includes third and fourth mixers with each mixer receiving at an input one of the low pass signals. At another input the mixers receive third and fourth signals. The third and fourth signals are derived from mixing a variable controlled oscillator (VCO) signal with the local oscillator guadrature signals. The outputs of the third and fourth mixers are applied to the inputs of a difference amplifiers, the output of which controls the frequency of the VCO in an automatic frequency control mode (AFC) to cause the output of the difference amplifier to provide demodulated signal. A switching means operates to alternate the third and fourth signals as applied to the input of the third and fourth means as well as the output as applied to the difference amplifier to cause an additional amplifier coupled to the outputs of the mixers to provide a DC control signal used for automatic gain control.

Title: Device for collecting emissions from kerosene heaters
IPC: F23C6/04
Filed: 1984-05-03
Abstract: An apparatus for both improving the heat distribution throughout a room from a portable kerosene heater and for collecting undesirable emissions resulting from the burning of the kerosene, includes a base adapted to be mounted on the top of the heater, the base supporting a vertically extending shaft on which is mounted a heat-driven fan formed of either paper or metal, and a disposable disk mounted a spaced distance above the fan on the same shaft, the disk serving as a collector for the undesirable emissions. When the device is placed on an operating kerosene heater, the rising hot air and gases from the heater cause the fan to rotate, which in turn causes emissions from the burning fuel to move upwardly in a more or less cylindrical path. As the products of combustion move upwardly, certain emissions therein such as soot, oily vapors, etc. deposit or condense onto the surface of the spinner and disposable disk.
