Title: Optionally cross-linkable coatings, compositions, and application methods
Inventor: MITRA SUMITA B
IPC: A61K6/896
Filed: 1994-12-02
Granted: 2001-03-27
Abstract: FIELD: stomatology. SUBSTANCE: invention relates to coatings for solid tissues such as dentine, enamel, cement material, and bone. Coating can also be applied on other surfaces in mouth cavity including surfaces of dental plugs and orthodontic and orthopedic dental ware. Coating composition contains polymer including repeating motifs of polar or polarizable group (1-80 wt %), modulating group (0-98 wt %), and grafted hydrophobic polysiloxane chain with molecular weight at least 500 (1-40 wt %). Coatings show low coefficient of friction and high resistance against plaques, bacteria, food coloration, etc. In addition, treatment of thus coated surface with composition containing a surfactant was unexpectedly found to reduce adhesion of bacteria and protein substances. Such treatment gives positive effects even in cases when surface was preliminarily exposed to action of bacteria and protein substances. EFFECT: increased protective capability of coating. 71 cl, 4 dwg, 30 tbl, 16 ex

Title: Pile and method for its driving into ground
Inventor: JAGIN V P
IPC: E02D5/50
Filed: 1997-06-10
Granted: 2001-04-27
Abstract: FIELD: construction engineering; building foundations from pre-fabricated piles including grounding stakes. SUBSTANCE: pile that can be driven into non-subsiding and subsiding grounds followed by reinforcement of ground by electric treatment upon its installation has bore pointed at one end, cap at other end, and expanded section with ledge closed around bore. Novelty is that pile is provided with at least one elongated projection made on side surface of expanded section; one end of projection is pointed and faces pointed bore end. Converged section closed around bore may also directly abut against expanded section on the side of cap; in case of driving bore into non-subsiding ground layer expanded section ledge is spaced from pointed end through distance exceeding or at least equaling rated depth of driving. Method for driving pile into ground involves bore driving into ground and filling gap with liquid material. Novelty in method is that blind area is made before bore clearance is formed and fluid material is introduced into blind area; at least bottom part of blind area is arranged in clay soil to prevent air-suction into clearance while pile is driven into ground. Bore clearance may be filled with antifriction and/or hardening, and/or current-conducting liquid material. EFFECT: reduced cost. 5 cl, 2 dwg

Abstract: FIELD: measurement technology, test and measurement of components of impedance of two-terminal networks displaying inherent emf, biological objects included. SUBSTANCE: technical aim of proposal is provision for rigorous simultaneous determination of values of parameters of impedance in the form of continuous analog signals dynamically adequate to each measured parameter with exception of necessity of usage of controlling signals whose frequency exceeds working frequency of measurement. In correspondence with method first sinusoidal voltage and two rectangular voltages synchronous with it are formed in step. Voltages are formed so that front of first rectangular voltage coincides with moment of transfer of first sinusoidal voltage through zero and front of second rectangular voltage is shifted with reference to specified moment through quarter of period. First sinusoidal voltage is fed to analyzed impedance with generation across its output of second sinusoidal voltage with amplitude proportional to modulus of analyzed impedance and phase shift relative to first sinusoidal voltage equal to phase shift of analyzed impedance. Processing of generated signal in the form of second sinusoidal voltage is carried out with simultaneous participation of first and second rectangular voltages by way of separate multiplication of each of specified voltages with second sinusoidal voltage with subsequent filtration of resulting signals. Value of active component of impedance is estimated by filtered resulting signal of multiplication of second sinusoidal voltage with first rectangular voltage and value of reactive component of impedance is conjectured by filtered resulting signal of multiplication of second sinusoidal voltage with second rectangular voltage. EFFECT: provision for simultaneous determination of values of parameters of impedance. 2 cl, 2 dwg
