Patent AT-E1894-T1 (AT)
IPC: C01B33/158

Granted: 1982-12-15
Abstract: Silica aerogel in the form of a substantially crack-free, preferably transparent block is described, together with a method for the preparation of such aerogel and use thereof in solar panels. The preparation is effected by means of hydrolysis of a tetraalkoxysilane, preferably tetramethoxysilane, in an alcohol, preferably methanol, in the presence of a catalyst, preferably ammonia, for the formation of an alcogel which is aged for approximately 10 days and washed with alcohol for removing water. The alcogel is thereafter treated in an autoclave by means of a temperature increase to above the critical point of the alcohol, isothermic pressure drop by means of the release of alcohol vapor, and temperature drop. The temperature increase, the pressure drop and the temperature drop take place at the such low mean rates that the aerogel does not crack. To this end, a total treatment time in the autoclave of at least 24 hours is required. After the autoclave treatment, a heat treatment at 500 DEG  to 750 DEG  C. is possibly carried out for further improving the transparency of the aerogel.

Abstract: A programmable pacemaker apparatus having a microprocessor and means for receiving program information from an external source, means for generating and delivering stimulus signals and means for sensing the occurrence of natural heartbeats in a patient, and having a battery source powering the apparatus, said microprocessor being combined with program instructions stored in memory for controlling the operation of said pacemaker, comprising controller circuit means external to said microprocessor and interconnected therewith for controlling the operating state of said microprocessor, said controller means having occurrence means for determining the occurrence of given events. The controller means further comprises means for stopping operation of the microprocessor on command from the microprocessor and for starting operation of the microprocessor upon determination of one of said events, whereby the microprocessor normally is on less than about 25% of the time. The pacemaker provides for at least two modes of pacing rate control, whereby the patient's heartbeat can be overdriven, or abrupt changes in rate are not followed beyond a selected rate change limit. Means are provided for microprocessor control of testing of pacemaker conditions, and for limiting current to the pacemaker output circuit when the battery voltage drops below a predetermined value.

Abstract: For sand blasting a stream of a suspension of a carrier gas and solid particles under superatmospheric pressure is restricted so that it is accelerated, and a liquid-carrying additive gas is mixed with the stream to moisten the particles. The additive gas is introduced into the stream at a pressure greater than the pressure of the stream at the location by between 1.5 and 2.5 times. Normally the additive-gas pressure is about twice the carrier-gas pressure, that is the additive gas is normally introduced at a pressure of between about 10 bar and 30 bar. This high-pressure introduction ensures that the additive gas enters well into the carrier-gas stream so that the liquid carried by the additive gas contacts and wets the solids carried by the carrier gas without just passing through it and wetting the inside of the sand-blast mix nozzle. The additive gas is introduced into the stream in a unit of time at a rate sufficient to introduce into the stream a quantity of the liquid equal to between about one-twentieth to one-thirtieth, preferably one-twenty-fifth, the mass of the particles passing the location during the unit of time.

Abstract: In a rotary printing machine, an arrangement for mounting an applicator roller and a preceding roller in a fluid feed stream journals the applicator roller and the preceding roller to the printing machine frame with substantial bearing play, and spring loads the applicator roller against the bearing surface away from the plate cylinder. On passing through the cylinder gap the applicator rollers of inking, damping or varnishing units in sheet-fed offset presses are jolted both at the start and end of the gap. The resulting different flattening of the soft applicator rollers causes roller marks, which should be avoided. For this purpose the applicator roller and the preceding roller are braced against each other by springs, so that their bearing play is eliminated and the distance between shafts is constant. This condition is also maintained on passage through the gap. Conveyance of liquid between applicator rollers and the preceding rollers is thus constant.

Abstract: A method for the manufacture of integrated MOS-field effect transistor circuits in silicon gate technology and wherein diffusion source and drain zones are coated with a high melting point silicide as low-impedance printed conductors. The diffusion zones and polysilicon gates are made low-impedance through selective deposition of the metal silicide onto surfaces thereof. The selective deposition, which proceeds by use of a reaction gas eliminating hydrogen halide, simplifies the process sequence and is fully compatible with conventional silicon gate processes. Because of the high temperature stability, preferably tantalum silicide is employed. The invention is useful in the manufacture of MOS-circuits in VLSI-technology.

Abstract: The pulse voltage for the electrode (12) of a dust separator (10) is generated by a thyristor circuit (19) to be transferred to a dust separator through a transformer (16). It being possible that voltage arcings take place at the dust separator (10), there is the risk, in case of a blocked thyristor (20) that from the secondary of the transformer (16) a high voltage is produced at thyristor (20) to destroy the thyristor. To avoid such an occurrence, a detector (27) is provided which is only responsive to sudden voltage drops whereupon the thyristor (20) is enabled to become conductive so that the energy of the secondary circuit may be discharged to the storage capacitor (24) in the primary circuit.

The tunnel (106) is provided with two columns of louvers (140) along its entire length through which the air from the duct (104) flows. Air exiting the louvers (140) is deflected by a baffle plate (146) which extends the full width of the rear of the cabinet (10). The edge portions (152, 154) of the baffle plate (146) are perforated. The air thus must move out forward through the louvers (140) then laterally across the solid portion of the baffle plate (146) before turning forward again through the perforations in the baffle plate into the interior of the cabinet (10). The improved air (low greatly reduces temperature differences within the carbinet (10) when used as an oven, and the air flow over the heating elements is more uniform, reducing hot spots and thus prolonging their life.

Abstract: The glycosides of resorufin derivatives have the general formulae Ia and Ib <IMAGE> in which R<1> is hydrogen, R<2>, R<3> and R<5>, which can be identical or different, are hydrogen, halogen or a lower alkyl group, R<4> and R<6>, which can be identical or different, are hydrogen, halogen, a cyano, lower alkyl, lower alkoxy, carboxyl, lower alkoxycarbonyl, carboxy-lower alkyl, lower alkoxycarbonyl-lower alkyl or an optionally mono- or disubstituted carboxamide group or the group  -COO-(CH2CH2O)n-R<7> in which R<7> is hydrogen or a lower alkyl group and n is an integer from 1 to 4, where R<6> can additionally be a sulphonyl or nitro group, and Y is a nitrogen or the group NO. These compounds are particularly suitable as chromogenic and fluorogenic substrates for determining the activity of corresponding glycosidases or oligosaccharide-cleaving enzymes. The glycosides are obtained by reacting resorufin derivatives with a mono- or oligosaccharide or a 1-halogeno derivative thereof, whose hydroxyl groups are substituted by customary protective groups. This initially results in per-O-substituted glycosides, which can be converted into the claimed compounds by elimination of the protective groups. The glycosides are used as chromogenic and fluorogenic substrates in diagnostic agents for detecting glycosidases or oligosaccharide-cleaving enzymes. The resorufin derivatives employed as starting materials in the preparation of the compounds are also claimed.
