Title: Optically active aliphatic alpha-halogen-substituted carboxylic acid 4'-(4-alkoxyphenylthiooxy)biphenylyl ester compound and process for producing same
Inventor: DEN EISAI
IPC: C07C327/20
Filed: 1991-04-05
Abstract: PURPOSE: To obtain a novel alkoxyhenyl thiooxo biphenylyl ester compd. that is effective as a base material for blending a liquid crystal or a dopant to improve characteristics of LCD.  
     CONSTITUTION: This compd. is expressed by formula I, wherein R is a 8 to 15C n-alkyl, C is asymmetric carbon, X is a halogen, and R' is a compound expressed by formula II, etc. For example, the compd. is 4'-(4-octoxyphenyl thiooxo)biphenylyl (2S, 3S)-2-fluoro-3-methylpentanate. The compd. is obtd. by the reaction of an ester of optically active fatty acid α-halogen-substd. carboxylic acid and p-(4-carboxy)biphenyl with alkoxythiophenol expressed by formula III in a pyridine solvent by heating and refluxing the mixture at 80°C for 12 hours. The compd. of formula I becomes the thioester without an ester compd. to be free and increases the selectivity of a liquid crystal compsn. the halogen directly bonded to the asymmetric carbon is effective in improving the self-polarization and electromagnetic response characteristic of a liquid crystal material and further effective in controlling the liquid crystal state.

Title: Blow-bye gas reflux unit
Inventor: MUKAI TAKESHI
IPC: F01M13/00
Filed: 1981-06-29
Abstract: PURPOSE:To prevent any undesirable influence on an engine having a double suction passage for improving engine performance in a partial load range, by allowing reflux of blow-bye gas through a high-load secondary suction passage only in said partial load range. CONSTITUTION:A separator 26 which separates mist of lubricating oil from blow-bye gas is disposed on a cylinder head cover 24, and connected to the second bleezer pipe 28, which is communicated with an air cleaner 20. The first bleezer pipe 30 is connected to a crankcase 22 while interposing a flow regulation valve such as a PCV valve 32 on the way, and is terminated at a reflux opening 34, which opens in the lower course from a secondary throttle valve 16 of a secondary suction passage 12. In a partial load range, blow-bye gas produced in the crankcase 22 is led in the first bleezer pipe 30 then passing through the PCV valve 32, flowing into the secondary suction passage 12 only, and then sucked into a combustion chamber 4 therefrom.

Title: Production of acid and alkali
Inventor: HANADA FUMIO
IPC: B01D61/46
Filed: 1992-04-20
Abstract: PURPOSE:To control salt concentration and simultaneously to find an abnormal phenomenon, such as a blister generated during electrodialysis by using water solution of salt from a salt chamber while circulating it and when cell voltage exceeds the set value, feeding new water solution of salt. CONSTITUTION:Three kinds of membranes, bipolar membranes B, anion exchange membranes A and cation exchange membranes C, are arranged in order between an anode 11 and a cathode 12 to form alkali chambers 13, acid chambers 14 and salt chambers 15. And for water solution of salt similar to water solution of acid and alkali, the salt chambers and a salt tank 24 are connected by a water solution of salt circulating line 25 and while the water solution of salt discharged from the salt chambers 15 is again returned to the salt chambers 15 through the salt tank 24 to circulate it, it is desalted. At that time, cell voltage is measured and when the voltage exceeds the set value new water solution of salt is fed to the water solution of salt circulating line 25 through a water solution of salt feed line 23. Therefore, the concentration of water solution of salt in the salt chamber is always suited for electrodialysis.

Title: An activated aerosol exhauster
Inventor: VEKTERIS VLADAS
IPC: F24F9/00
Filed: 2010-12-30
Abstract: An activated aerosol exhauster is intended for sucking aerosols from surfaces and reducing in amount in the sucked air. It can be used for collection of aerosols from the liquid surfaces in tanks of different size and temperatures. The tanks are used for performing various technological operations and processes. A compressed air flow is delivered to a collector and the stream of increased turbulence is formed by its blades thanks to its twisting. Due to different turning directions between the nearby twisters, the stream of the increased turbulence is formed. Through the branch pipes the twisted stream flows into spherical reflectors which act as the turbulence amplifiers and direct the flow over the pollution source. Flowing over the pollution source the stream of increased turbulence activates the coalescential effect of liquid particles in aerosol and returns a part of aerosol pollution back to the surface. Air flow together with the residual pollution is sucked from the surface by a cylindrical exhauster.

Title: Water economizer in toilets.
Inventor: BURRUEL JUAN FRANCISCO SALCIDO
Filed: 1996-07-26
Abstract: This invention discloses a water saving device which is placed inside water reservoirs of conventional toilets. The device is independent from components already available in the toilet. It does not require any modification or addition neither to the water reservoir nor to any of the parts thereof, nor specialized personnel for its installation. Water saving is obtained by graduating the device so as to discharge only the necessary amount of water to dispose of liquid wastes (urine) with the option of discharging all the water in the case of solid wastes (fecal matter). With the option to save from 30 percent to 70 percent water, depending on reservoir capacity, and user will. Water is scarce nowadays, and in some regions, severe measures are being taken to save this vital liquid, such as rationalization. We waste water in many ways, but there is one in particular which is "covered" and which is not considered to be a waste, and this is excessive water to discharge urine in toilets. If this waste is responsibly fought, we can save millions of water liters every day per city. This invention function covers two objectives: economical and ecological.
