The communication satellite (101) includes an error detector (211) and a comparator (215). The UET (105) includes a receiver (206) for receiving an error indicator signal from the comparator (215), and a power profile processor (216) for controlling the transmit power level of the particular chanslot being used by the UET in response to the error indicator. A preferred method for controlling the transmit power level of a particular chanslot assigned to a UET in a satellite communication system in accordance with the present invention includes determining an error count for an uplink data signal received from the UET in the chanslot (403), and comparing the error count to a predetermined error threshold (404). The method further includes generating an error indicator signal for the chanslot in response to the comparison (405), and controlling the transmit power level of the particular chanslot in response to the error indicator (409, 410).

Abstract: Coordination of processing satellite uplink transmission and downlink transmission is achieved by an uplink encoder (418) and uplink modulator (420) which incorporate an adjustable IF amplifier (417) at a ground terminal (400). Information about data traffic transmission errors detected in a satellite (100) is formed into ATM traffic report cells by a cell former (157). The traffic report cells are sent on the downlink to the ground terminal. The traffic report cells are used to adjust the power level of the IF amplifier for the particular channel and slot for which errors were detected.

Abstract: A method of determining backlash wherein one member of a gearset is rotated in a first direction and rotary positions are recorded at predetermined increments. The rotary positions of the other member of the gearset are recorded simultaneously with those of the one member. The direction of rotation of the one member is reversed and rotary positions are recorded at the same increments while simultaneously recording the rotary positions of the other member. The difference in recorded positions for the other member are calculated thus representing the amount of gearset backlash.

Abstract: A measuring probe comprises a stylus-carrying member on which a stylus is magnetically retained. The carrying member is supported on a flat diaphragm spring for tilting movement relative to an intermediate member. The intermediate member is supported on two further diaphragms for linear movement relative to a housing. The spring rates of diaphragm and further diaphragms are chosen to give the probe the desired relative force/displacement characteristics in X,Y and Z.

Abstract: A system for data communication between ground stations using an orbiting satellite as a relay includes a technique for avoiding the loss of signals from the satellite during periods of heavy precipitation. Data is communicated from an orbiting satellite to a plurality of earth stations on a single transmission frequency. The data is communicated on two separate transmission channels on that one frequency by using orthogonal channels of a coherent phase quadrature transmission system. The overall data rate on one of the two transmission channels is much lower than the overall data rate on the other of the two channels. The data on the lower data rate channel is less likely to be affected by heavy precipitation occurring in the line of sight between the satellite and the ground station, and the lower data rate channel is thus used to communicate data to a ground station located in an area of heavy precipitation. The lower data rate channel is further used to maintain phase synchronization so that the probability of losing phase synchronization with the signal transmitted by the satellite is significantly reduced.

Abstract: An improved gravitational separator for mixtures of immiscible liquids of different densities, particularly oil and water, includes a reaction member in the form of a dome or diaphragm immersed in more dense liquid to be separated and which floats upwardly in the more dense liquid under the influence of liquid of less density accumulated beneath the dome or diaphragm. A coalescer screen filter system is provided in the water outlet path in the separator, the coalescer screens being contained in a chamber provided with automatically operating, one-way, pressure responsive valves to ensure proper flow of water in a forward and backflush sense through the chamber. A flotation feature for the reaction member is provided, and the reaction member includes an auxiliary air chamber to prevent loss of a minimum desired residual layer of less dense fluid beneath the reaction member when air accumulates in this area. A specific inflow and outflow conduit arrangement is provided to minimize turbulence in the separator. An oil collection system is provided to carry backflushed oil from the coalescer to the inlet conduit of the separator.
