Abstract: A ratiometric system for autonomous lubrication of oilwell production equipment. In one arrangement a lubrication pump is fluidly connected to a stuffing box on an oilwell pumping unit. The interval for lubrication and the duration of lubrication is managed by an event sequencer that is electrically connected to the well controller for the pumping unit. The well controller senses a completed cycle of the pumping unit and produces an electronic pulse that can be counted. The event sequencer counts the pulses as they occur. A lubrication cycle is triggered when the sequencer reaches a count corresponding to a predetermined value. The amount of lubrication supplied is directly related to the number of completed cycles of the pumping unit.

Abstract: An antenna apparatus includes multiple antenna elements each performing at least one of transmission and reception of radio waves. The coverage areas of main lobes of radiation patterns of the multiple antenna elements are overlapped with each other and the shapes of side lobes thereof are varied among the multiple antenna elements. With this configuration, it is possible to discriminate and acquire the signal of the radio waves coming from the coverage areas of the main lobes of the antenna from the signal of the radio waves coming from the outside of the coverage areas.
