Title: Light-weight grouting mortar
Inventor: OVCHINNIKOV V P
IPC: C09K8/473

Granted: 2005-01-10
Abstract: FIELD: oil and gas production. 
     SUBSTANCE: invention relates to grouting mortars used for cementing casing pipes of gas, gas-condensate, and oil wells complicated by presence of formations with low hydraulic rupture pressure as well as presence of permafrost rocks. Light-weight grouting mortar contains 47.0-60.0% special-type cement, 6.6-11.8% clinoptilite as light-weight additive, and water. As a result, casing-pipe annulus incidents during boring and running wells are avoided owing to improved parameters of grouting cement, in particular increased sedimentation stability of mortar, dimensional stability and needed strength of cement stone at low positive and negative temperature in early hardening stages are achieved at simultaneous lowering of grouting mortar density.

Granted: 2005-07-20
Abstract: FIELD: the invention refers to modes of measuring the parameters of electromagnetic radiation. 
     SUBSTANCE: the mode is executed in the following manner: electro-magnetic radiation is polarized by way of transmitting through two immobile polarizers the polarization axles of which are oriented every other 45 degrees relatively to each other. Two beams of polarized radiation fall on the two-area photoreceiver where the radiation in its turn is transformed in electric signals which are reinforced by the preliminary intensifiers and served on the schemes of selection and storing. Sequential serving of an analogue signal on the analogue-digital transformer is executed with the aid of an analogue commutator. The digital code of the analogue signals is served with an analogue-digital transformer on a microprocessor system where transformation of signals is executed according to an algorithm corresponding to above described mathematical model. Using of a polarized-sensible two-area photoreceiver leads to reducing noises at the expense of reducing the number of used sensible areas. 
     EFFECT: the invention increases the accuracy and quick-acting measuring of the extent of the polarization of radiation.

Abstract: FIELD: electric engineering-electromagnetic mass accelerators, applicable for propelling of ferromagnetic bodies. 
     SUBSTANCE: the device consists of coils with a cylindrical non-magnetic barrel for the propelled body located inside them in the axial line, means for separate supply of each coil, and means for switching of the supply circuits of each coil.  The coils are made with magnetic circuits.  Each pair of coils positioned side by side is embraced by a magnetic circuit that is common for these two coils.  Besides, each of three successively positioned coils has spaced (turned relative to the barrel axis) magnetic circuits - the first magnetic circuit is turned relative to the second magnetic circuit around the barrel axis in such a manner that the influence of the magnetic leakage fields on one another would be minimized.  The first of these magnetic circuits embraces the first and second and third coils, etc.  A non-magnetic section is available between the magnetic circuits, they form practically independent and not coupled to each other magnetic circuits.  The length of the ferromagnetic working area of the propelled body equals 3hx2L, where h - the distance between two coils, L - the coil thickness.  Capacitors serve as a supply source of each coil.  The parameters of the control means of the keys switching the supply circuits of each coil are selected so that after switching-on of the supply of the first coil at movement of the propelled body the current in the first coil would be switched on, and the supply of the second coil would be switched off after the supply of the third coil is switched on.  The switching of the subsequent coils is effected in a similar way.  As a result, the current of the secondary induction amplifies the magnetic field of the subsequent coil when the supply of the preceding coil is switched off. 
     EFFECT: enhanced efficiency of conversion of the electromagnetic energy to kinetic one.
