IPC: B65D47/34
Filed: 2012-04-05
Abstract: ABSTRACT A method for dispensing a product from a container that can obtain duration discharge upon a single turn of an actuator sleeve to pressurize product and ready it for dispensing. The method includes rotating the actuator sleeve in one direct for 3600 or less relative to the container, drawing an amount of the product into a pump chamber. When an actuator of a power assembly is temporarily depressed, a valve is opened which dispenses a portion of the product from the pump chamber through a nozzle during the time when the actuator is temporarily depressed. Releasing pressure on the actuator permits the valve to return to the closed position and re- depressing and re-releasing pressure on the actuator one or more times until substantially all the product in the pump chamber is dispensed through the nozzle.

Title: Improved methods for landfill volume reduction
Inventor: OPPENHEIM JUDITH P
IPC: B09B3/00
Filed: 2019-07-23
Abstract: Systems and methods for reducing the volume of construction and demolition (C&D) debris waste are described. The systems include a torrefaction unit that reduces the hardness of the waste while degrading it into volatiles and particles having a range of sizes. The variation in particle size allows for a more efficient compaction due to minimal void space and the imparted softness allows for increased compressibility. This results in the processed debris having a much smaller volume than had it not undergone the presently described methods, which reduces landfill tipping fees and extends the life of the landfill.

Filed: 2019-04-30
Abstract: System and methods for simulating fluid flow during downhole operations are provided. Measurements of an operating variable at one or more locations within a formation are obtained from a downhole tool disposed in a wellbore within the formation during a current stage of a downhole operation being performed along the wellbore. The obtained measurements are applied as inputs to a hybrid model of the formation. The hybrid model includes physics-based and machine learning models that are coupled together within a simulation grid. Fluid flow within the formation is simulated, based on the inputs applied to the hybrid model. A response of the operating variable is estimated for a subsequent stage of the downhole operation along the wellbore, based on the simulation. Flow control parameters for the subsequent stage are determined based on the estimated response. The subsequent stage of the operation is performed according to the determined flow control parameters.

Abstract: The present invention provides a digital optical fiber-based distributed signal control system. The system mainly comprises a wireless signal access control module, a detection module, and a private network module. By means of reasonable frequency allocation and pre-selection filtering processing, modules can work together to implement control and detection of unauthorized mobile phone signals and guarantee communications of legal mobile phones, thereby achieving efficient coverage of a signal control area. A main control signal generated by a main control signal unit (SU) and an auxiliary control signal generated by a remote unit (RU) are mixed according to an algorithm, to achieve a better control effect in the entire signal control area. The present invention can achieve large-range efficient coverage by a digital optical fiber remote form, and greatly reduces the costs of the system while achieving the overall signal control target. In addition, in order to achieve control signal coverage in a larger range, GPS  synchronization can be employed to make several identical control systems work together to achieve distributed coverage at kilometers level.
