Abstract: Die Erfindung bezieht sich auf ein außenvertrahntes Stirnrad mit einem geteilten Radkörper. Um einen Einsatz derartiger Stirnräder bei höheren Drehzahlen und höheren Umfangsgeschwindigkeiten zu ermöglichen, ist der Radkörper durch mindestens eine achsnormale Trennfläche (T1) in Zahnringe (ZR1, ZR2) unterteilt, wobei jeder Zahnring (ZR1, ZR2) durch im Bereich des Zahngrundes verlaufende Trennfugen (T2, T3; T4, T5) in mindestens zwei Ringsegmente (RS1, RS2; RS3, RS4) unterteilt ist und wobei die Trennfugen (T1, T2, T3, T4) der Zahnringe (ZR1, ZR2) in Umfangsrichtung versetzt zueinander angeordnet sind. Damit sich bei der Montage des Stirnrades keine Teilungsfehler einstellen können, wird der aus Ringsegmenten (RS1, RS2, RS3, RS4) zusammengefügte Radkörper vor dem Herstellen der Außenverzahnung auf einen Dorn aufgeschrumpft. Das erfindungsgemäße Stirnrad eignet sich insbesondere als Ersatz-Stirnrad für einteilige Stirnräder, die zum Antrieb von Turbomaschinen-Hilfseinrichtungen bestimmt sind. Beim Einbau des Ersatz-Stirnrades braucht dann die entsprechende Welle nicht ausgebaut zu werden.

Abstract: Phosphate rock is digested with H 2 SO 4  into phosphoric acid and gypsum, the latter is separated off, washed and converted into anhydrite. After this first wash the gypsum is divided into a minor portion of fine crystals, which is discharded, and into a major portion of coarse crystals, which is subjected to a second wash, thereafter recrystallized into anhydrite by means of concentrated H Z SO 4 , the anhydrite being separated and washed and the recrystallization liquor returned to the digestion zone. The washing liquor obtained from the anhydrite wash is used for the second gypsum wash, the washing liquor obtained from this second wash is, together with water, used for the first gypsum wash, whereas the washing liquor obtained in this first wash is returned to the digestion zone. In this way practically all gypsum formed can be converted into anhydrite, while substantially all water can be functionally used without dilution of the H 3 PO 4 -product.

Abstract: An arrangement for adjusting the value of an electrical component, for example a potentiometer, by means of rotatable shaft (10) comprising first (1) and second (2) pulleys and a cord (4) passed round the pulleys in a figure of eight configuration. A control lever (3) is movable through a first angle, typically 60°, and is effective to rotate the shaft (10) of a potentiometer (11) through 300°. The first and second pulleys (1,2) are arranged with their rims in contact at point (6) so that side thrust on the potentiometer spindle (10) caused by the tension in the cord (4) is resisted by the contact between the pulleys. In order to prevent slip between the cord (4) and the pulleys (1, 2) the cord is clamped (42, 44) on each pulley and the ratio of the rim radii of the pulleys is made equal to the ratio of the core radii of the pulleys. 
     The arrangement may be used in television studio and outside broadcast equipment such as video tape recorders, special effects generators and remote controllers.

Abstract: The analogue signal is fed to converting unit 1 of small capacity but high resolution. When the input signal exceeds the capacity of unit 1 an over-signal is supplied to a digital memory 3 which, by way of a D-A conversion unit 5 and an analogue subtractor 6, subtends from the input signal an integral multiple of the output of unit 1. The corresponding digital amount is added to the output of unit 1 by the adder 4. When the input to converter 1 is within its capacity, an under-signal is fed to memory 3 and determines the extent of the subtraction.

Abstract: Surfactant-modified, 1,1,2-trichloro-1,2,2-trifluoroethane solvent compositions are provided which contain small but effective amounts, i.e., about 0.2 to about 0.5 weight percent of solvent soluble/water insoluble surfactant and/or surfactant demulsifiers and adjust to accommodate. Of particular significance are the compositions containing N-acylated sarcosine surfactants and demulsifiers of the group acetylenic diols, aliphatic primary alcohols of 6 to 12 carbon atoms, and alkyl phosphate triesters of 3 to 12 carbon atoms. The demulsifier containing compositions have the properties of effectively and essentially completely displacing water or aqueous solutions from many substrates and, even under conditions of severe agitation, separating them for removal by decantation from the solvent layer without the drawback of forming stable emulsions that prevent said decantation and interfere with sufficient processing of the solvent drying compositions through the drying apparatus.

Abstract: @ The present invention relates to cross-sectional shape of a silicon gate electrode of an insulated gate field effect transistor. The gate electrode is composed of polycrystalline silicon, and its length, in cross section, gradually increases from the surface contacting to the gate insulating film toward the central portion thereof and then gradually decreases toward the upper surface thereof. 
     The central portion of the polycrystalline silicon has the largest length in the source-drain direction and contains small amount of Si0 2  particles. Relying upon this gate shape, the portion having largest length, can be used as a mask to introduce impurities in a self-aligned manner to form source and drain regions. The thus formed source and drain regions create small capacity relative to the gate electrode. Therefore, a high speed transistor is realized.
