Patent MX-9504892-A (MX)
Title: Curved drilling apparatus.
Inventor: WARREN TOMMY M
IPC: E21B7/06
Filed: 1995-03-10
Abstract: A rotary drill bit (22) for drilling a curved subterranean borehole (26). In one embodiment, the drill bit comprises a side portion (40), a plurality of cutting elements (44) that produce a lateral force on the drill bit (22) in response to the rotation of the drill bit in the borehole, and bearing means (48). The bearing means is located on the side portion (40) of the drill bit (22) and contacts the borehole wall (28) during drilling to receive a reactive force that is from the borehole, that is in response to the lateral force and that is directed to a location adjacent to the uphole end of the side portion of the drill bit (22). The reactive force and the lateral force form a downhole-moment that is about the drill bit and that is opposed by an uphole-moment having a force component that is directed at the flexible joint (186). The uphole end of the bearing means (48) is located relatively close to the cutting elements (44) such that the magnitude of the downhole-moment and the magnitude of the uphole-moment are minimized.

Patent MX-9702227-A (MX)
Title: Method and apparatus for applying multiple speech processing features to a telephone call.
Inventor: BEGEJA LEE
IPC: H04M1/00
Filed: 1997-03-25
Abstract: A speech processor uses a plurality of sppech processing features to enhance the quality of speech signals received by a user during a telephone call. The activation of a second speech processing feature is delayed for a time duration measured after the initiation of a particular call or measured after the activation of a first speech processing feature. This delay eliminates any interference between the second speech processing feature and the frist speech processing feature that is active when the call is initiated. The delay also increases the time it takes for the speech processing features to become fully effective, thus making the enhancement in the quality of the speech signals more noticeable to the user. Further, an optionally generated audio indicator is provided when the second speech processing feature is applied so that the additional feature is even more noticeable to the user.

Patent MX-9709157-A (MX)
Title: Fluid delivery apparatus.
Inventor: KRIESEL MARSHALL S
IPC: A61M5/14
Filed: 1997-11-26
Abstract: This invention is an apparatus (370) for accurately infusing fluids into a patient at specific rates over an extended period of time. The apparatus is of a low profile, laminate construction having a stored energy source in the form of a distended membrane (406), which in cooperation with the base (372) of the apparatus defines one or more fluid reservoirs (388) each having a fluid inlet and a fluid outlet. The apparatus (370) further includes a novel, conformable ullage made of formable materials. The conformable ullage (404) uniquely conforms to the shape of elastomeric membrane (406) as the membrane (406) returns to its less distended configuration, and in so doing can move between a central chamber and a toroidal chamber formed in the cover of the apparatus. This arrangement will satisfy even the most stringent medicament delivery tolerance requirements, and will elegantly overcome the limitations of material selection encountered in devices embodying solely rigid ullage construction. Additionally, the infusion cannula (386) of the apparatus is connected to the base (372) in a novel manner which permits expeditious subdermal delivery to the patient via a cannula (386) which extends generally perpendicularly relative to the base.
