Abstract: A granular carrier is contacted in a reaction space with a continuous stream of liquid which contains a sufficiently wide flora of microorganisms and sufficient nutrients for the growth and /or preservation of the microorganisms until a sufficiently thick layer of microorganisms is attached to the carrier, while in the liquid 0.1-1.5 kW of mechanical energy per m' of reactor liquid, is dissipated at least partly in the form of gas bubbling through the liquid and the residence time of the liquid in the reaction space is kept lower than the reciprocal maximum growth rate of the microorganisms. More preferably an aerobic biomass attached to a carrier is produced, by applying liquids, wherein the growth rate is not limited by the concentration of nutrients and by adjusting a residence time of the liquid in the reactor of below 45 minutes. 
     The process can be applied for the production of all kinds of biomass attached to a carrier, e.g. biomasses as are applied in the biological purification of waste-water, aerobic biomass, anaerobic biomass, nitrificating biomass and denitrificating biomass, as well as biomasses forming a desired metabolic product which inhibits its own production rate at higher concentrations, e.g. biomass for the production of alcohol.

Abstract: A composition of matter is disclosed comprising dimethylmagnesium, di-n-propylmagnesium and optionally diethylmagnesium. The composition is soluble in aliphatic, cycloaliphatic and aromatic hydrocarbon solvents without the aid of solubilizing agents. The composition is prepared in the substantial absence of oxygen and moisture by the simultaneous or consecutive reactions of methyl, ethyl, and n-propyl halides with metallic magnesium in the presence of the hydrocarbon solvent, followed by separation of the insoluble magnesium halide and any unreacted magnesium metal from the resulting solution. The compositions are useful in providing dialkyl magnesium compounds of high magnesium content which are soluble in hydrocarbons.

Abstract: A method comprising combining a silicate ester and water under hydrolysis conditions in the presence of a sufficient amount of solvent that the reaction mixture remains as a single phase, adding sufficient acid neutralizing agent to form a gel and separating solvent and water from the resulting silica. In a preferred embodiment, the ester and water are added to a very small amount of solvent, the addition of water being sufficiently slow that it is added at about the rate it is used up in the hydrolysis reaction. The resulting silica does not require the washing step to remove alkali metal ions since it is not made from sodium silicate, and it has large pore structure because it can be made in a relatively concentrated solution because of the use of only a minimum amount of solvent and also because the hydrolysis is carried out under conditions wherein only a single phase is produced. The resulting silica is suitable for chromatographic columns and fillers in rubber and plastics but is of primary utility as a base for a chromium oxide catalyst because of its simplicity in production and inherent large pore volume.

Abstract: The counter circuit is adapted to counting high frequency pulses and to being read while counting said pulses. It comprises a plurality of pulse counting stages of increasing numerical significance, and read means for reading the states of said stages. Said plurality of pulse counting stages comprises lower significance stages (101 to 104) connected as a synchronous counter (10) and higher significance stages (121 to 12n) connected as a ripple counter (12). The synchronous counter is so connected that it counts the high frequency pulses (H) directly, and that any change of state required in any of its stages on counting a pulse occurs substantially simultaneously with the arrival of said pulse. The ripple counter is so connected that it counts count cycles of the synchronous counter, and that it takes a long time relative to the interval separating two successive high frequency pulses for a change of state to propagate, where necessary, from the least significant stage (121) of the ripple counter to its most significant stage (12n). Early count signal means (244) are provided to apply a count signal to the ripple counter during each count cycle of the synchronous counter at an instant which is early relative to the synchronous counter cycling from its full count to its empty count. Further, the read means (49) are provided with read timing means (244 and 57) for causing the state of the ripple counter to be read regularly at a predetermined synchronous counter state.

Abstract: A process and apparatus for reducing the environment- polluting effect of gases containing solid and liquid particles originating from a source, particularly the exhaust gases from an internal-combustion engine (10) involves passing the gases to be purified into a purifier (1) where an electric charging electrode (4) charges them electrically. Then the gases are caused to flow through a set of electrode plates (7) in the purifier (1). The charged solid and liquid particles contained in the gases are precipitated on the plates (7), which may be electrically charged and neutral or charged to a polarity of opposite sign to that of the charging electrode. The velocity of the gas flow in the purifier (1) may be regulated not to exceed 1 m/s. A mechanical separator may be connected in the purifier (1) downstream of the electrode plates (7). The electric charging increases the chemical activity of the oxygen as well as of the pollutants present in the gases.

Abstract: Disclosed is a radiant energy optoelectronic position monitor system which detects the angular position of a "galvanometer mirror" (beam scanner) (gm) used in an optical disk memory arrangement. 
     Using a single infra-red monitor beam, angular motion is converted to linear displacement of an image on a detector cell (31) so as to produce a corresponding electrical signal. This signal is presented to a processing circuit with an analog divider to normalize output scale factor. The result is a high gain electrical circuit for recovering output signals in an environment with strong magnetic interference. 
     Such a position sensor is described as especially apt for use in a "three beam" laser optical system comprising a writing beam and two reading beams all incident on the samt track of a rotating disk optical recording medium. One of these reading beams is incident on the track ahead of the writing beam so as to serve as a "read-before-write" beam, while the other reading beam is incident on the track behind the recording beam so as to serve as a "read-after-write" beam.
