Granted: 1982-04-27
Abstract: ABSTRACT OF THE DISCLOSURE         The system described herein is particularly adapted to convert mechanical energy from a wind or hydraulic driven turbine into electric energy and comprises:  an exciter generator and a main generator in a housing traversed by a rotatable shaft;  the exciter generator consists of permanent magnet mounted to the housing envelope and of a rotor mounted to the shaft and having a one-phase winding, the rotor being made of non-magnetic material to eliminate cogging and static torque associated with permanent magnet excitation;  the main generator consists of a three-phase stator winding on a magnetic core mounted to the housing envelope and of a pole-type rotor mounted to the shaft, the rotor having a winding wound on a magnetic core; a rectifying bridge is rotatably mounted to the shaft and is connected to the one-phase winding of the rotor of the exciter generator and to the winding of the main generator rotor so that the rotation of the shaft as a result of mechanical energy generates a three-phase electric energy output from the stator winding.

Abstract: ABSTRACT OF THE DISCLOSURE   A method is provided herein for the electrochemical corrosion pro-tection of a stainless steel member which is periodically subjected to vary-ing concentrations of a corrosive oxidizing solution of chloride ions, e.g., a partly submersed, rotating, stainless steel drum in a vat containing a cor-rosive, oxidizing, chloride-containing bleach liquor.  The method comprises the step of impressing a protection potential to the stainless steel member, e.g., drum at a predetermined voltage in the range of -600 to ?400 ?V Ag/AgCl. This predetermined voltage is sufficiently low to draw the stainless steel into a passive corrosion protection zone. However, that voltage is not suf-ficiently low to draw the stainless steel into a zone of uniform corrosion. Specific means for the placement of the anode in the vat are also provided.

Abstract: ABSTRACT OF THE DISCLOSURE An anchor bolting assembly for mounting into a borehole of a rock structure, the rock structure having an outer face exposed around the borehole, includes a frangible capsule for insertion into the borehole.  The capsule contains a flowable anchoring resin and a segregated catalyst for solidifying the resin when the capsule is ruptured and the resin and catalyst mixed.  The assembly also includes a threaded bolt member for insertion into the borehole, the bolt member having an inner end for rupturing the frangible capsule and mixing the resin and catalyst contained therein, and a free end.          The assembly further includes a bearing plate member for mounting on the free end of the bolt member and for engaging the outer face of the rock structure.  The assembly also includes a nut member having an inner end portion for abutting against the bearing plate member, an opposed outer end portion, and an interiorly threaded through aperture for receiving the free end of the bolt member.  The nut member further includes temporary stop means for engaging the bolt member so as to resist the complete threading of the nut member onto the free end of the bolt.  Thus, while the anchoring resin is flowable, rotation of the nut member against the temporary stop means effects the simultaneous rotation of the bolt member and the mixing of the resin and catalyst within the borehole.          The temporary stop means is deformable such that when the anchoring resin has solidified around the inner end of the bolt member, thus non-rotatably fixing it within the borehole, continued rotation of the nut member provides sufficient torque to overcome the temporary stop means and permit the nut member to be completely threaded onto the free end of the bolt member, thus tightening the bearing plate member against the outer face of the rock structure and tensioning the bolt member within the borehole.

The retaining limbs are inserted into the prepared holes and the transverse portions of the units are thus arranged to define a mesh-like arrangement anchored at least partially by the retaining limbs.  The end regions of the transverse portions are anchored to and linked together to hold the transverse portions against the earth formation.  The units normally have at least two retaining limbs and these limbs are forced into the holes to a depth of between about 0,5 and 2 metres.          Formations maybe provided in the limbs to inhibit removal of the limbs.

Abstract: ABSTRACT OF THE DISCLOSURE Manufacturing method of doped silica glass suitable for optical fiber wherein quartz powder or SiO2 glass fine particles are exposed to a gas for producing the doped silica glass containing SiCl4, a gaseous additive and water vapor (H2O) to add the dopant to the glass body, and then the resulting glass body is fused at a high temperature, thereby producing a transparent doped silica glass in which the production of the glass particles, the addition of the dopant, and the vitrification of the glass body are carried out by separate steps under respective suitable conditions.  The manufacturing speed is remarkably increased because of the separate steps.  Content of dopant is not limited, but can be adjusted with any desired amount by changing a reaction time of dissolution.  Dopant components like PbO2, SnO2, ZnO which is hardly added to the glass body can be added.          Manufacturing method of optical fiber preform wherein the doped silica glass is deposited and fused on a starting material which is inclined by an angle within a range of 5 - 90° with respect to a blow-off direction of the flow of the doped silica glass to form a transparent doped silica glass body having a uniform outer diameter and a uniform boundary surface at a high synthesizing speed. This aids mass production of optical fiber at a low cost.
