Title: Self-centering polycrystalline diamond drill bit
Inventor: AZAR MICHAEL G
IPC: E21B10/54
Filed: 1995-12-20
Abstract: A self-centering drill bit includes a head portion having a plurality of polycrystalline diamond compact cutting elements arranged in blades that extend outwardly away from a surface of the bit.  A cavity is centrally located on the head portion and is formed between adjacent blade ends.  The cavity includes wall portions defined by the blade end portions. The cavity serves to house a core portion that is formed during drilling operation of the bit. The head portion is balanced to form and transmit a force from a designated wall portion to the core portion within the cavity.  At least the designated wall portion includes a low friction abrasion resistant surface.  The cavity includes a rigid element extending outwardly away from the head portion to reduce the core within the cavity upon contact. The force transmitted to the core portion causes a countering force to be imposed by the core to the wall portion that keeps the bit aligned with its rotational axis and, thus prevents whirling.

Title: Railway switch mechanism
Inventor: GIRAS THEO C
IPC: B61L5/06
Filed: 1996-01-05
Abstract: A linear induction rail switch mechanism having at least one linear induction motor (LIM) for transversely thrusting a switch track from a first position to a second position. To reduce the frictional forces during transverse movement, the switch mechanism can be levitated from the underlying structures. The switch can have at least one controllable power supply which may supply electric power to an individual LIM or groups of LIMs, which may be three-phase motors. The switch may include a vital controller which is connected to at least one controllable power supply. The vital controller responds to at least one of a feedback signal from a controllable power supply, a feedback signal from a LIM, a feedback signal from a switch track, and a remote signal. The LIM may include a primary inductor which is affixed substantially rigidly to the ground and a secondary which is affixed to the switch track. In some embodiments, the secondary may be a ladder secondary. When the LIM is energized, the ladder secondary becomes magnetically attractable to the primary inductor, and thus the ladder secondary becomes movable responsive to the magnetic field generated by the primary inductor. The controllable power supply used with the switch can include a solid state power converter having a controlled output voltage, which may employ a pulse-width-modulation scheme. The solid state power converter may be a variable-voltage, variable-frequency converter, although a variable-voltage fixed-frequency converter also may be employed.

Abstract: L'utilisateur d'une serrure à combinaison électronique auto-alimentée fait tourner un cadran extérieur (101) afin que des générateurs génèrent de l'énergie qui sera stockée dans une banque de condensateurs. L'utilisateur fait ensuite tourner un cadran intérieur (102) afin qu'un microprocesseur affiche en séquence des combinaisons de chiffres, et appuie sur le cadran intérieur (102) pour sélectionner un nombre affiché.

Filed: 1997-02-18
Abstract: A system for temperature compensating and regulating secondary pressure in a hydraulic circuit for an automatic transmission, includes a viscosity insensitive fixed orifice and a relatively high resistance laminar orifice connected in series relationship between a vent port and a control pressure supplied to a secondary regulated pressure SRP valve.  At relatively low temperature, flow through the laminar orifice is negligible; therefore, the steady-state differential pressure across the fixed orifice is negligible.  At relatively higher temperatures, flow through the laminar orifice increases.  A pressure divider is established and the feedback differential pressure is reduced in proportion to the hydraulic resistance of the two orifices.  Flow to friction elements from a primary pump and auxiliary pump and return of fluid to the inlets of the pumps is controlled through a clutch capacity pressure regulator valve acting in cooperation with the SRP valve.
