Granted: 1997-09-16
Abstract: Creating the capability of a meet-me-conference call on a telephone terminal by actuation of a meet-me-conference button on the telephone terminal. The meet-me-conference button is actuated for a particular line appearance, and the meet-me-conference is then established by other telephone terminals calling the telephone number associated with that line appearance. The user of the telephoneterminal can join the conference at a later point in time by going off-hook. As other parties call that line appearance, the telephone terminal adds them to the conference. As parties join the conference, their names are displayed on the telephone terminal, and a second button on the telephone terminal can be utilized to drop parties as they are added to the conference. A second actuation of the meet-me-conference buttonprevents further callers to the line appearance from being added to the conference.

Abstract: A process for making a thin, sealant-coated, tire and indentation resistant gypsum panel from at least 2 homogeneous layers of fiber-reinforced gypsum. A layer of a mixture of cellulosic fibers moistened with water and an additive to restrict the adhesion of cellulosic fiber to one another, is deposited on at least two separate conveyors to form a fibrous matt on each conveyor and a layer of dry calcined gypsum containing set accelerator is deposited on the fibrous matt on each conveyor.     The deposits on each conveyor contain, on a dry weight basis, about 70% to about 90% by weight gypsum, about 10% to about 19% by weight cellulosic fiber and about 1% to about 9% by weight of combined additive and set accelerator. Each layer on each conveyor is directed to a mixing station to form a homogeneous layer, and the formed homogeneous layers on separate conveyors are placed atop one another on a single conveyor to form a combined homogeneous layer. The combined homogeneous layer is subjected to pressure (compressed) to form a pressed, homogeneous fiber-reinforced gypsum panel. A sufficient amount of water is added to the layer or layers to rehydrate the calcined gypsum.     The pressed, homogeneous fiber-reinforced gypsum panel is dried, and the surface of the dried panel is sealed with a wax-free, water resistant sealant. Sealant-coated, fire resistant, indentation resistant gypsum panels having a thickness of about 0.25 inch and having a density of about 60 to 80 lbs./ft.3 are made from 2 homogeneous layers of fiber-reinforced gypsum.

Abstract: A steerable rotary drilling system comprises a bottom hole assembly which includes, in addition to a drill bit, a modulated bias unit and a control unit including an instrument carrier which is rotatable relative to the bias unit. The bias unit comprises a number of hydraulic actuators spaced apart around the periphery of the unit, each having a movable thrust member which is displaceable outwardly for engagement with the formation. Each actuator can be connected, through a rotatable control valve, to a source of drilling fluid under pressure, the control valve comprising a first part, rotatable with the instrument carrier, which co-operates with a second part which is rotatable with the bias unit. Means are provided to roll stabilise the instrument carrier so that relative rotation between the bias unit and instrument carrier, as the bias unit rotates, causes the valve to operate the actuators in synchronism with rotation of the bias unit so as to apply a lateral bias thereto. In order to neutralise or reduce the net bias applied to the bias unit the instrument carrier may be rotated in various modes instead of being roll stabilised, e.g. it may be rotated at a constant slow speed relative to the bias unit, or at a significantly faster rate so that the actuators do not have time to operate fully. The angular velocity of the carrier may also be varied during its rotation, according to various formulae, in order to vary the net bias. The net bias may also be varied by alternating different modes of carrier rotation.
