摘要： A rotating blowout preventor having at least two rotating stripper rubber seals which provide a continuous seal about a drilling string having drilling string components of varying diameter. A stationary bowl is designed to support a blowout preventor bearing assembly and receives a swivel ball that cooperates with the bowl to self-align the blowout preventor bearing assembly and the swivel ball with respect to the fixed bowl. Chilled water is circulated through the seal boxes of the blowout preventor bearing assembly and liquid such as water is pumped into the bearing assembly annulus between the stripper rubbers to offset well pressure on the stripper rubbers. Lubricant is pumped into shaft bearings and serves to prolong the life of shaft. pressure seals by offsetting well pressure against the shaft pressure seals and clamp mechanisms are used to tighten the stripper rubbers on the respective mounting elements in the bearing assembly and swivel ball. A method for sealing a drilling string at the surface of a well, which method includes the steps of mounting a rotating blowout preventor having at least two sealing stripper rubbers on the well casing or other equipment connected to the well casing, in swiveling relationship, inserting a drilling string through the rotating blowout preventor and stripper rubbers, introducing a liquid into the rotating blowout preventor, circulating water around certain pressure seals and application of hydraulic pressure on the stripper rubbers and pressure seals to offset well pressure exerted against the stripper rubbers and pressure seals.

摘要： A housing has a length adjustable to match the length of the bee entrance of a common type of brood chamber and a width at least equal to the width of that bee entrance. The housing includes screened openings or other ventilation provision to permit air to pass through the bee entrance of the brood chamber. One or more arms or other clamping device on the housing holds the housing securely over the bee entrance to prevent bees from entering or leaving the brood chamber. The device facilitates transport of bees as well as laboratory control of African bees.

摘要： There is disclosed an improved drilling head which provides for the formation of a continuous seal about a drilling string, where the drilling string consists of varying diameter drill string components. A stationary bowl configured to pass a drill string is provided with an annular grove about the top so as to allow for the attachment of a connecting clamp. An assembly carrier is provided which is removably disposable within the bowl and to which a lower stripper rubber may be attached. A bearing assembly adapted for placement within the assembly carrier is provided with an upper rotatable stripper rubber of smaller diameter that the lower stripper rubber so as to form a seal on smaller diameter drilling strings.

摘要： A variable capacity chiller or hydronic heat pump with a compressor, a pump, and a condenser fan where system capacity is controlled by the speed of the compressor, pump, and/or condenser fan based on the flow rate and ΔT between the returning water temperature and leaving water temperature, where the compressor, pump, and fan adjust automatically to match the changing load conditions to match the capacity to the load, and which includes a psychrometric climate controller that manages a chiller or chiller heat pump to heat or cool a heat transfer fluid in communication with indoor heat exchanger(s) and where the setting for the entering or leaving heat transfer fluid temperature can be automatically varied based on psychrometric data or on information derived from such sensors, and when in heating mode, to dynamically manage an external backup resistance heat source to accurately match any shortfall of heating capacity.

摘要： A system and method for starting a compressor is provided. An amount of liquid refrigerant that is located in an oil sump of the compressor is determined. Using the determined amount of liquid refrigerant, a starting algorithm for the compressor is selected. The selected starting algorithm is configured to remove the determined amount of liquid refrigerant from the oil sump before the compressor reaches a preselected operating speed. The selected starting algorithm is then executed to start the compressor.

摘要： A bumper rail assembly is provided that uses bars of arch-shaped spring steel, mounted in a standing-arch configuration, as shock absorbers for the bumper rails. An end portion of the spring steel bar is shaped into a saddle so that the spring steel bar can be secured indirectly, by means of a metal plate or bracket, to the concrete base. The assembly minimizes shear forces on the anchor bolts, offers performance advantages over conventional shock absorbers such as used tires, and is economically competitive with conventional shock absorbers.
