Abstract: This patent document describes systems and methods for tracking the usage of a service provided by a distributed computing platform and for the enforcement of a global quota against such usage. In one embodiment, Servers in the platform are organized in a hierarchical manner. At the lowest tier resides a set of globally distributed servers, any one of which may receive and respond to client device requests. Multiple tiers of aggregation servers sit above the above the delivery tier. The first tier of aggregation servers receive usage measurements from the delivery tier. The second and higher tiers aggregate the usage measurements from lower tiers until a world level tier combines all usage measurements for a given service. Preferably, usage information is passed between servers in synchronization events. The systems and methods described herein are scalable, low latency, fault-tolerant, and incur relatively low computing overhead.

Abstract: Disclosed is a method for manufacturing thin sheets of high-strength titanium alloys. The method includes the steps of preparing initial blanks, assembling the initial blanks into a pack within a sheath, and heating and hot rolling the pack of the initial blanks in the sheath. The method is characterized in that, in the step of preparing the initial blanks, blanks having an (?-phase grain size of not more than 2 ?m are produced by hot rolling a forged or die-forged slab to a predetermined value of a relative thickness hB/hF, where hB is a thickness in mm of the initial blank before said pack hot rolling and hF is a final sheet thickness in mm, and by heat treating the initial blanks followed by rapidly cooling; and in that the step of pack hot rolling is conducted in quasi-isothermal conditions in longitudinal and transverse directions, while changing a rolling direction by about 90° after a predetermined total reduction in one direction is achieved.

Abstract: The inventive titanium-based alloy contains 2.2-3.8 mass % aluminium, 4.5-5.9 mass % vanadium, 4.4-5.9 mass % molybdenum, 2.0-3.6 mass % chromium, 0.1-0.4 mass % zirconium, 0.01-0.18 mass % iron and 0.03-0.25 mass % oxygen, the rest being titanium. Said alloy exhibits a high processing plasticity in hardened condition thereof associated with a high strength. The alloy has a high temperature range, thereby making it possible to use it not only for screw heads and helical springs but also for producing large-sized semi-products whose cross section ranges up to 60 mm and which are used in high temperature conditions.

Abstract: Metastable ?-titanium alloy contains, in mass %: from 1.5 to 3.5 aluminum; from 4.5 to 8.0 molybdenum; from 1.0 to 3.5 vanadium; from 1.5 to 3.8 iron; titanium balance. This alloy combines high strength and ductility. This allows to use it for production of a wide range of critical parts including fastener components and different coil springs (e.g. in automobile industry).

Abstract: In a thin-walled structure being cleaned, there are generated converging waves of elastic deformation by virtue of synchronous excitation of single equal pulses along the contour of the surface being cleaned in the points opposite to one another. To effect this method use is made of an electromagnetic source (1) of mechanical pulses in combination with a waveguide (2) transmitting mechanical pulses to the structure (4) being cleaned and representing a ring (8) with a disk (9) designed to accommodate the source (1) and connected to this ring by jumpers (10).

Abstract: The method for acceleration of liquid and bulk materials comprises conversion of energy of the electromagnetic pulse of a radiator (1) into mechanical energy applied to the treated material by a plate element (3) of a conducting material having at least one degree of freedom in the direction of acceleration. The opposite surfaces of the place element (3) at the moment of emission of the electromagnetic pulse are brought in physical contact with the radiator and treated material, respectively.An apparatus for realization of the above method comprises a radiator (1) connected with a source (2) of electromagnetic pulses, a plate element (3) of a conducting material arranged loosely on the radiator (1), the surface of said element being intended for placement of the treated material.

Abstract: The invention is an electronic sensor for producing an indication of fluid level in a hose or tube and an electronic indicating circuit that uses the sensor's indication of fluid level for asserting one of three indicators depending upon whether the fluid level is above a reference by a small distance, within the small distance of the reference, or below the reference by the small distance. A float retaining a core having a relative magnetic permeability significantly greater than one is supported by fluid near three vertically disposed coils. The center coil is excited by a source of alternating current and the position of the core above or below the center coil determines the voltages present in the top and bottom coil. The voltages present in the top and bottom coils are rectified and added in polarity opposition to produce an indication of fluid level. A plurality of voltage comparators, supplied by the indication of fluid level and fixed voltages, are used to assert the appropriate indicator.

Abstract: A method for disintegrating a material comprises acting on the material being disintegrated with shock waves produced upon applying individual electromagnetic field pulses to a current-conducting element arranged in a close proximity to the material being disintegrated. An apparatus for disintegrating a material comprises a unit forming electromagnetic field pulses connected to a current source and arranged in a close proximity to the current-conducting element.

Abstract: The method for mixing substances employs a reciprocating movement provided by mechanical impulses. The apparatus for mixing substances comprises a reservoir, a mixing means, a reciprocating movement mechanism of the mixing means, which mechanism includes eddy current electromagnetic inductors coupled to a current source having a storage capacitor, a turn-on sequencer for said inductors, and elements made of electrically conducting material. The invention substantially improves the effectiveness of the mixing operation and provides for increased labor, productivity, and reduces the power requirements needed to drive the apparatus.
