Abstract: CONSTRAINED RIPPLE SPRING ASSEMBLY AND METHODS OF INSTALLATION                      ABSTRACT      A constrained ripple spring assembly 26 is disposed in the slots 12 of a rotor 10 forming part of a dynamoelectric machine and between the stator windings 14 and the wedges 20 maintaining the windings in the slots. The ripple springs 28 are adhesively secured to flat surfaces, for example, the underside of the wedges or one or two filler strips 30, 32, such that the spring assemblies are substantially flat upon insertion.  At a predetermined elevated temperature, the adhesive bond is broken, enabling the spring to expand into a natural corrugated shape to apply a loading against the wedges and winding.

Title: Process for recovering aluminium and fluorine from fluorine containing waste materials
Inventor: KAABER HENNING
IPC: C01F7/30
Filed: 1992-02-04
Abstract: Aluminium and fluorine are recovered from fluorine containing waste materials from the production of aluminium metal (FCWM) as AlF2OH hydrate by a process comprising: leaching FCWM with dilute sulphuric acid at a pH value within the range 0-3, if needed adding aluminium in an acid soluble form; adjusting the pH value of the aqueous phase to a value within the range 3.7-4.1 at the end of the leaching period by addition of a caustic aqueous solution;  precipitating silica at a temperture not exceeding 60 ·C;  separating the reaction mixture into a solid phase containing precipitated silica and non-soluble residues of the FCWM and a purified solution; and precipitating AlF2OH hydrate from the purified solution at a temperature within the range 90-100 ·C and at a pH value not exceeding about 4.1 by controlled continuous addition of an aqueous caustic solution. Reducing and/or non-oxidizing operating conditions are maintained during all these process steps. The precipitated AlF2OH may be calcined at a temperature within the range 500-600 ·C to produce AlF3, Al2O3, which is expedient for use in processes for the production of aluminium metal by electrolytic production of alumina.

Abstract: ABSTRACT OF THE DISCLOSURE    A  router accessory used in concert with a router attached to a router table.  The accessory can be used to produce rosettes, model wheels, buttons, coasters, and other circular decorated projects, for example.  In the preferred embodiment, a wooden workpiece can be positioned horizontally above a selected router bit.  The workpiece zero point, which may be the workpiece center, can be off-set horizontally from the router bit.  The accessory can then be used to lower the workpiece onto the router bit, so that rotation of the workpiece routs a circular cut equidistant from the workpiece zero point.  The maximum depth of cut can be set.  The off-set can be changed to make additional circular cuts into the workpiece, as desired.

Inventor: BASH STEPHAN R
IPC: H04M3/42
Filed: 1994-04-20
Abstract: When a caller making a collect call encounters a busy called party or one that does not answer after a prescribed time, the telephone network offers the caller the opportunity to store a voice message in a messaging system at no charge to the caller. After the caller stores a message, one or more attempts are made to establish a connection between the messaging system and the called party's telephone. This may be done by periodically alerting the called party's telephone when it is in an on-hook state. When the called party answers, e.g., by going off-hook, the messaging system informs the called party that a collect voice message awaits him and asks if he is willing to pay to receive same. If the called partysignals that he is willing to pay to receive the voice message, the messaging system plays the stored voice message from the collect caller and signals the telephonenetwork to charge the account of the called party for supplying the message. If the called party signals that he is unwilling to pay to receive the voice message, the message is not delivered.

Title: Mercury removal from liquid hydrocarbon fraction
Inventor: TAN SHOJI
IPC: B01D15/00
Filed: 1994-12-20
Abstract: Mercury is removed from a liquid hydrocarbon fraction by effecting high-temperature heat treatment to convert an organic mercury compound into an inorganic mercury compound or elemental mercury, removing a higher molecular weight component from the fraction, removing water from the fraction, and thereafter contacting the fraction with an adsorbent in the form of active carbon having calcium or a calcium compound supported thereon. Although only a minor amount of mercury is contained in the liquid hydrocarbon fraction, mercury can be efficiently removed at low cost on an industrial large scale, achieving an extremely low mercury concentration.
