Abstract: Method and apparatus for refining pulp stock in which the pulp material is ground in a grinding space (34, 42) defined between a pair of rotatable grinding discs (18, 20) having ridges and grooves providing opposing grinding surfaces (26,28,30,32), which discs (18,20) rotate relative to one another in an environment of a fluid medium under superatmospheric pressure and correspondingly elevated temperature in a housing (10). The grinding space includes a first grinding zone (34) extending from a central portion of the discs and a second grinding zone (42) extending angularly from the first grinding zone (34). The first grinding zone (34) is defined between the relatively rotatable discs (18, 20), while the second grinding zone (42) is defined between one of the rotatable discs (18) and a stationary grinding surface (44) on at least a portion of the surface of a stationary element (46) mounted within said housing (10) and spaced apart from the other (20) of said rotatable discs to provide a gap for preventing contact between the periphery of said disc (20) and said stationary element (46).

Abstract: Appareil de traitement electro-medical destine au traitement de tissus biologiques. L'appareil de traitement est surtout destine a accelerer les processus de cicatrisation dans des parties du corps blessees ou malades par hyperemie, c'est-a-dire suralimentation localisee de sang et flux sanguin accru. Ceci est obtenu en partie en appliquant un champ magnetique transversalement a la direction longitudinale des vaisseaux sanguins dans la partie du corps a traiter, et partiellement en appliquant un champ electrique transversalement a la fois a la direction longitudinale des vaisseaux sanguins et au flux du champ magnetique. De cette maniere, les particules chargees electriquement inclues dans le sang, les ions, sont affectees pour effectuer des mouvements rotatifs en forme d'helice, augmentant ainsi le flux sanguin dans les tissus. L'appareil de traitement electro-medical consiste principalement en un generateur de champ electrique contenant des electrodes de champ (5, 6) et au moins un systeme de lentilles (2). Les solenoides (3, 16) et les elements d'electrodes (5, 6, 19-22) inclus dans l'appareil de traitement recoivent une tension variant regulierement creant des champs electriques et magnetiques a impulsions. Un champ magnetique et/ou electrique approprie a chaque situation du traitement et a chaque lesion est engendre de telle maniere que la tension d'alimentation puisse etre reglee a volonte.

Abstract: In the preparation of pivaloyl cyanide of the formula (CH3)3C-CO-CN by reaction of pivalic acid anhydride with anhydrous hydrocyanic acid, the improvement which comprises carrying out the reaction continuously in the presence of a catalyst comprising an alkali metal/copper cyanide complex, an alkaline earth metal/copper cyanide complex or an alkali metal salt, or an alkaline earth metal salt, of an aliphatic, cycloalkphatic or aromatic, carboxylic acid, or a precursor of such a salt, in either case optionally in admixture with a Lewis acid, and in the presence of an inert, aprotic organic diluent, which boils above about 210 DEG  C., at a temperature between about 180 DEG  and 240 DEG  C., by simultaneously and continuously dropping the pivalic acid anhydride and introducing the hydrocyanic acid in gaseous form into a stirred suspension of the catalyst in the diluent, and continuously distilling the crude product mixture consisting essentially of pivaloyl cyanide, pivalic acid and unreacted hydrocyanic acid, the unreacted hydrocyanic acid being separated off by evaporation and being recycled to the reaction vessel, and the pivaloyl cyanide being separated from the precipitated crude product mixture by fractional distillation in vacuo. Advantageously the reaction is carried out at a temperature between about 195 DEG  and 225 DEG  C., the complex cyanide of the formula Na3[Cu(CN)4], K3[Cu(CN)4], Ca3[Cu(CN)4]2 or Ba3[Cu(CN)4]2 is employed as the catalyst, diphenyl ether is employed as the diluent, and about 1 to 2 moles of pivalic acid anhydride and about 5 to 8 moles of hydrocyanic acid are introduced into the suspension of catalyst per hour.

Abstract: The power supply for a plurality of loads, especially high-voltage D.C. loads such as electrical filters, comprises preferably two-pulse part-wave rectifiers (TS1, TS2, TS3), allocated to the individual loads (F1, F2, F3) which are in each case connected to two phases of a three-phase network (R S T), while the opposite pole of the load supply is formed by a common, uncontrolled part-wave rectifier (TSg). The latter is of three-pulse design and is connected to all phases. The part-wave rectifiers allocated to the loads are designed as controlled rectifiers and allow individual voltage setting, despite the reduced complexity. <IMAGE>

Abstract: An optical position sensor comprises a linear element or a disc (22) carrying stripes or rings coded with reflecting and non-reflecting areas. Light pulses of short duration from a source (12) are transmitted through a transmission line (15) coupled to optical fibres (20a to 20e) of differing lengths, whose ends (21a to 21e) are opposite the coded channels. When a reflecting area is opposite the fibre end, light is reflected back along the fibre and transmission line and returned to a light detector (25a) as a sequence of pulses. These pulses are applied to a shift register (26) from which they may be read in parallel form into a processor (31). A clock system (24) controls the light source and provides clocking pulses for the shift register, and, by means of a counter (29), a periodical pulse for resetting the shift register between the coded pulse sequences. A variable delay (27) permits the pulse sequences received at the shift register to be synchronised with the clock. 
     In a modification (not shown in Figure 1), the fibres may be coupled at sequential points along the transmission lines, and the transmission line may have a Y coupler to one arm of which the light source is coupled while the other serves for coupling the detector.

The holders (30) are constructed as complementary concave profile blocks (25) for the slides (31) to receive the pressure forces. Thus no rotatable parts are required on the binding. The binding can be accommodated in a compact and flat manner in an otherwise unused hollow space in the sole of a ski boot (19) and the holders (25, 30) themselves are considerably flatter than in conventional shapes. <IMAGE>
