Patent NL-7500076-A (NL)
IPC: D06M101/16
Filed: 1975-01-03
Abstract: A woven fibrous ion-exchange fabric is initially formed from fibers as in the form of threads, ropes or yarns which comprise a fluorinated polymer with sulfonyl-containing pendant side chains in the -SO2X form wherein X is fluorine or chlorine. Conversion of the sulfonyl group in the polymer to ionic form causes longitudinal shrinkage of the fiber in the woven fabric and lateral fiber swelling thereby forming an essentially impermeable fabric to physical flow of liquid through spaces between the fibers. High strength is realized in the woven fabric without a need for reinforcing material.
Patent NL-7512808-A (NL)
Title: Glass plates or pans for cooking - constructed in composite layers to reduce the temp. of the surface in contact with food
IPC: C03C17/02
Filed: 1975-10-31
Abstract: A plate of heat resistant glass used in a cooker or a pan is made in sections. Radiant heat is supplied below the plate and the heat passes through the glass to the top. The lower section of the glass is transparent to wavelengths between 0.7 and 5mu m. The upper section is bonded to the lower one. It is considerably thinner than the lower section. It absorbs radiation in the wavelength range 0.7-5 mu m. Used in glass plates or pans used for cooking. Heat transfer through the top section is by conduction. This lowers the temp. of the top surface and reduces burning of material in contact with it. Heat is not reflected back to its source so that a temp. regulator at the source is not heated and the heat supply is uninterrupted.

IPC: E02D19/10
Filed: 1979-12-03
Abstract: Filter tube has channels for injection, completely sepd. from the draining channel of the filter tube, the bottom end of which is closed. A source of pressurised water or air can be connected to the top of the filter tube, so that it can be rapidly inserted into the ground without an injector lance or a mantle tube.

Title: Heating lamp for incubator - gives continuous temp. regulation and can reduce temp. over period of days using electronic unit and temp. sensor
IPC: A01K31/20
Filed: 1982-05-21
Abstract: This lamp assembly provides heat for incubating piglets, birds or other creatures. An electronic unit provides continuous regulation of the temp. by altering the power delivered to the lamp filament. The temp. variation is over a much smaller range than that achieved by using a conventional thermostat to switch the lamp off and on. The unit can be programmed to reduce the temp. steadily over a period of days, thus preparing the animals for outside temps. A temp. sensor (8), which is positioned just within the beam of light (9) from the lamp (1) and reflector (2), is connected to the control unit (4). The latter, inside a tube (3) on the neck of the lamp, has two controls: one (5) to set the required temp., and another (6) to set temp. reduction times.

Title: Environmental kinetic to electrical conversion using magnetic flux - energy from kinetic particles or photon field into electron current in conductor surrounding permanent magnet
IPC: H02N11/00
Filed: 1987-04-13
Abstract: The energy conversion method uses a permanent magnet (11) which is installed in the space within a sec. coil (13) which lies within and concentric with a pref. superconducting prim. winding (12). The axis of magnetisation lies in a plane parallel to the upper and lower boundary planes of the coils (12, 13), which are accommodated between thermally conductive plants (14, 16) of e.g. Cu or Al with outwardly projecting ribs (15, 17) of the same material. Alternating current through the prim. coil (12) generates an alternating magnetic field at right angles to that of the magnet (11). The resultant field traverses the sec. coil (13) and induces a useful voltage in it. Energy drawn from the sec. coil (13) is replaced by heat transfer from the surroundings through the plates (14, 16) and ribs (15, 17) on either side of the structure.

Title: Control circuit for piezoelectric element of translator - uses integrated feedback signal to reduce nonlinearity problems
IPC: H01L41/04
Filed: 1988-03-30
Abstract: The trigger input (3) is fed between one input of a comparator (2) and earth. The output of the comparator is fed via a voltage amplifier (4) to one terminal of the ceramic piezo-electric element (P). The other terminal of the piezo-electric element is connected via a resistance (Rs) to earth. The junction between the element and the resistor provides a feedback signal which is integrated (1) and fed to the other input of the comparator. The circuit ensures a linear relationship between the trigger input signal and the dimensional change of the element. It also limits unwanted hysteresis and time-denpendent 'creep' effects which would occur without the feedback loop.
