Abstract: Abstract A process for producing alumina from bauxite by the Bayer process.  Bauxite slurry is pressure digested in caustic soda solution to dissolve aluminum hydroxides in the bauxite as sodium aluminate while leaving most of the remaining constituents of the bauxite in solid form as red mud.  The red mud is separated from the digested slurry to obtain a caustic-aluminate pregnant liquor, alumina hydrate is precipitated from the pregnant liquor and the alumina hydrate is calcined to obtain the alumina.  The separation of the red mud from the digested slurry is carried out at a temperature above the boiling atmospheric temperature of the liquor phase of the slurry.

Title: Electrode substrate with integral edge seal and method of forming the same
Inventor: ELMORE DAN E
IPC: H01M8/02
Filed: 1989-02-23
Granted: 1992-10-20
Abstract: Abstract of the Disclosure Electrode Substrate with Integral Edge Seal and Method of Forming the Same The edges of a porous substrate plate used in a fuel cell power plant are densified by impregnating a suspension of finely divided material in the interstitial spaces in the plate edges.  The suspension, in the form of an "ink" is forced into the plate edges via a pressure differential applied through the plate between two press blocks.  The ink is forced into the plate after a catalyst layer has been applied to one surface of the substrate plate.  The ink thus penetrates to the inner surface of the catalyst layer, and also forms an integral filler band outwardly of the catalyst layer, which filler band has a top surface which is coplanar with the top surface of the catalyst layer.  After the impregnation step, the seals are dried to form a dense low porosity border on the substrate plates which will fill with electrolyte to form a wet seal that prevents gas crossover through the edges of the substrate plates.

This fastener means includes a shank (1) and a head (2) intended to be deformed by flattening during installation. On its front face, this head has an annular groove (5) extending around the axis and positioned in proximity to the alignment of the exterior surface of the shank. This groove defines on the head two portions, one central (2C), the other peripheral (2P), able to be deformed independently under the effect of flattening. The invention enables a considerable improvement of the distribution of compressive forces between the fastener means and the materials to be assembled. It assures a satisfactory radial expansion of the head, as well as a sufficient flow of material toward the shank and the junction zone between shank and head.

Abstract: Control device for a lockable gas spring ABSTRACT The invention relates to a control device for a gas spring which can be locked as desired by displacement of a sliding control finger.  Two axially elongated, diametrically opposed windows (14), at least one of which is larger at the end nearest to the gas spring, pass through a tubular connector (1) coaxial with the control finger (6).  A lever (2) which has thinner parts (25, 26) flanking a wide part (24) engages in these windows.  Devices (7) are provided so that, after mounting on the gas spring, the wide part (24) is unable to reach the wide section of the window, thus preventing the lever from being dislodged. The edges of the windows (14) form bearing points for the pivoting movement of the lever and the actuation of the control finger (6).

Abstract: The (+)-isomer of cloprostenol of formula (I):       in combination with the (-)-isomer, viz. a racemate, belongs to a significant group of prostaglandin F2 alpha analogues which have found wide use in veterinary medicine.  However, only the (+)-isomer of cloprostenol exhibits significant luteolytic  effects  whereas  its  (-)-isomer  shows  just antagonistic effects.  The (+)-isomer of cloprostenol may be prepared from an optically active lactone (-)-isomer from which a lactol is obtained by a regio-selective reduction and is then converted by the action of an -ylide to a protected derivative which,  after having been deprotected, gives the product of formula (I).  In veterinary practice to control livestock oestrus and to induce birth in sows,  the (+)-isomer exhibits better tolerance (since only fractions of the usual doses need be administered) which is also very interesting from an economic standpoint.

Abstract: ELECTROSTATIC SPRAY COATING SYSTEM     ABSTRACT OF THE DISCLOSURE           In an electrostatic spray coating apparatus (10),  liquid  coating  material  is  applied  to  a workpart inside of a spray booth (12).   Alternating flows of liquid coating material, liquid solvent and air  are  conducted  through  various  internal  flow passages in a conduit (14)  inside the spray booth. An  electronic  differentiator  (24)  is  positioned adjacent a predetermined location along the conduit (14) and energized from an electrical source disposed outside  of  the  spray  booth  (12)  to  differentiate between liquid and gas in the internal flow passage for nonintrusively detecting when the head of liquid flow reaches the predetermined  location  along the internal flow passage.   This is accomplished by an electromagnetic field extending into the flow passage and sensing the changes in the electromagnetic field resulting from dielectric differences between liquid and gas in the flow passage.

Abstract: A magnetic bearing having contactless position stabilization of a supported body which includes a damping and aligning arrangement. This arrangement includes two spaced rotating annular permanent magnets which form a gap therebetween and which are attached to a rotor supported by the bearing. A stationary plate having good electrical conductivity and extending into the gap between the permanent magnets, is cut by their rotating magnetic flux. Mechanical disturbances of the rotor generate eddy-currents in the conductive plate which currents damp out these disturbances. A portion of the plate outside the gap is much thicker than the portion in the gap and provides a very low resistance path for the eddy-currents.
