Patent BG-48772-A1 (BG)
Title: Method and installation for increasing the pressure of gases
Inventor: IVANOV IVAN D
IPC: F01K25/00
Filed: 1987-02-03
Abstract: The method and equipment are applied in the chemical, gas processing and metallurgical industries. They reduce energy consumption for increasing the pressure of gases and the equipment is simple. The gas is initially compressed to an intermediate pressure value which enables subsequent liquefaction by cooling and then it is primarily cooled in a heat exchanger - evaporator (2) and then in the condenser (3) cooled by an external refrigerating agent, where the liquefaction process is completed and is fed to the pump (5) through a collector for liquid gas (4) where the pressure is increased to a value higher or equal to the desired final pressure. Then the liquefied gas is fed to the same heat exchanger-evaporator (2) for heating and evaporation and enters a gas turbine (6) coupled to a compressor (1) where it expands to the desired end pressure.

Title: Optical switches using cholesteric or chiral nematic liquid crystals
Inventor: SHANKAR NARENDRA K
IPC: G02B5/30
Filed: 1990-04-27
Abstract: ABSTRACT     Fiber optic switches using layers of cholesteric or chiral nematic liquid crystals (CLCs) are disclosed.  The CLC layer acts both as a polarization beamsplitter and as a reflector by decomposing incoming unpolarized light into two orthogonal circularly polarized components.  In a number of embodiments, switchable waveplates are employed to controllably switch the polarization direction of each of the polarization components.      The components are then reflected back toward the CLC layer where they are recombined into a transmitted unpolarized beam.  The direction of transmission depends on the circular sense of the polarized components, and therefore on the state of the switchable waveplates.  In other embodiments, the CLCs are used actively by selectively exposing them to electric or magnetic fields or to heat which cause a phase change that temporarily neutralizes the circular polarization effect.  In this manner, the CLCs can be used as switch elements themselves.

Abstract: VARIABLE FLOW SELF-CLEANING  VALVE PREFERABLY FOR  VENTRICULAR OFFTAKE BRANCHES OF CEPHALORACHIDIAN FLUID.                             ABSTRACT            The present valve,  employable by persons  affected by  hydro-cephalus, permits discharge into suitable offtake branches  of the excess cephalorhachidian fluid existing in the  ventricles of the  brain.  The  valve  basically  consists  of  a  hollow cylindrical  body  (1)  having  inside  a  seat  (5)  with  an enlarging  triangular  shape  designed  to  interact  with  an aptly-shaped capsule or small piston (6) and placed against an antagonist spring  (7). This  pattern  permits to  offset  the varying amounts  of ventricular  fluid pressures,  discharging outside any fluid,  whether large or  small, through  suitable offtake branches  and  at  the same  time  it  accomplishes  a self-cleaning  function   which   ensures  a   constant   flow efficiency.

Filed: 1990-08-01
Abstract: Disclosed is a unique vehicle system which provides a desirable rheology to products formulated therewith, enhanced dispersion of actives therein, and improved deposition of actives therefrom. This vehicle system comprises a primary thickening agent which is a nonionic long-chain alkylated water-soluble polymer, and a secondary thickening agent which is a water-insoluble surfactant dispersed in a compatible solvent. Optionally, a rheological aid, which is a chelating agent may be included in the vehicle system. Also, optionally, a distributing aid, which is a water-soluble polymer of either high molecular weight or strong ionic character may be included in the vehicle system. These vehicle systems are useful in cosmetic compositions which are used to deliver an active component to the hair or skin. The vehicle systems are particularly useful in hair care compositions, especially rinse-off hair conditioning compositions, because they effectively deliver the hair conditioning component to the hair without depositing a substantial amount of the vehicle material onto the hair.
