Inventor: LEHMANN JUERGEN DR-ING
IPC: C12M1/12
Filed: 1987-04-25
Abstract: An apparatus for cell cultures in which the cultures are in a sealed container in at least one liquid medium, in which the medium or the media can be fed to the container and removed from the latter via intermediate filters, is to be designed in such a manner that filters are used which have a considerably longer holding time and in which clogging is impossible. The invention provides that a flexible filter fabric is suspended in a sealing but at the same time easily movable manner, it being possible for the filter to be moved within the medium.

Abstract: An active filter with switched capacitors for the traffic broadcast signal of a VHF receiver shows an inverting first amplifier and a second amplifier, an analog shift register with at least two register stages and an adder. The shift register is connected to the output of the inverting first amplifier and the adder adds the output signals from the second amplifier and shift register and sends the summation signal to the first amplifier. The switching frequencies of the capacitors and shift register are rated equal to twice the frequency of the filter input signal multiplied by the number of a register stage in the shift register. In a filter of this type used to filter the MPX signal, the critical capacitive ratios are in the order of 1:1, so that, with high precision, only a small area is required for the manufacture of the capacitors using SC-MOS technology. <IMAGE>

Abstract: A self-starting portable tool comprises a cylinder (104) in a housing (102), a piston (130) being mounted in said cylinder (104), means (164) for igniting and exploding a mixture of fuel and air in a combustion chamber (120) to drive said piston (130) to operate a working member (132), return means for causing said piston (130) to move upwardly from a lowermost position to an uppermost position of rest including outlet means (156) in said cylinder (104) between its ends. Thereby, a portion of combustion gases is forced to exhaust from said combustion chamber (120) to ambient atmosphere and a reduction in temperature of the combustion gases remaining in the combustion chamber (120) is caused. Said return means further include bumper means for initially moving said piston (130) upwardly from said lowermost position, said combustion chamber (120) above said upper face (130A) of said piston (130) being out of communication with ambient atmosphere during the further return of said piston (130) which return is substantially caused by producing an upwardly acting pressure differential on the upper and lower faces (130A, 130B) of said piston (130) induced by the reduction in temperature of the combustion gases above the upper piston face (130A).

Abstract: An acoustic transmitter for borehole logging includes a flexure disc acoustic source affixed to one end of an openended pipe. A rubber boot surrounds the pipe and flexure disc source and fluidly isolates them from the surrounding borehole fluid. Oil fills the rubber boot and pipe, such that the borehole fluid pressure is transmitted through the rubber boot to the oil. The flexure disc source is electrically excited to cause the transmitter to generate acoustic energy tube waves at one of the resonances of the flexure disc source within the seismic frequency range.

Abstract: There is provided a photo sensor for an image reading apparatus suitable for use in facsimile apparatus or image reader. This apparatus comprises: a light shielding layer arranged on the surface of a substrate which can transmit light; an insulative layer arranged on the light shielding layer; a photoconductive semi­conductor layer arranged on the insulative layer; and protective layers arranged on the photoconductive semiconductor layer. The reflected light of the light irradiated onto the original surface from the back side of the substrate is received by the photocon­ductive semiconductor layer, thereby reading the image information. The light shielding means are provided on the sides of the substrate and protective layers. The light shielding means is made of sub­stantially non-light transmitting organic resin and/or paint of a dark color. The image information is read by the one-dimensional line sensor which relatively moving the original in contact with the sensor. With this apparatus, the deterioration of the photo sensor by the stray lights is reduced and the good S/N ratio is obtained and the apparatus can be used for a long time.

Abstract: Ruthenium in aqueous solution in a first, oxidisable oxidation state (e.g. as RuNO(NO₃)₃) is converted to an insoluble form in a second, different oxidation state (e.g. as RuO₂.nH₂O) by establishing an electrochemical cell wherein the solution is the electrolyte and electro­chemically oxidising and reducing the ruthenium in the cell. The insoluble form may be filtered from the liquid. The ruthenium treatment may be a stage in the removal of radioactive species from liquids such is in the treatment of medium and low level activity liquid waste streams, wherein actinides are precipitated and filtered off either before or after ruthenium treatment. Subsequently, residual activity may be removed from the stream by either or both of (a) absorption, followed by filtration and electro-osmotic dewatering and (b) electrochemical ion exchange. Filtration fluxes may be maintained by direct electrochemical membrane cleaning.
