Title: Working fluid and supersonic compressor for thermally powered heat pumping applications
Inventor: SCARINGE ROBERT P
IPC: C09K5/00
Filed: 1988-12-21
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE    An improved thermal energy transfer apparatus and associated working  fluid  employs  a  supersonic  compressor  in  place  of  a conventional turbine-compressor unit within a Rankine heat engine powering a vapor compression heat pump.  The compressor comprises a supersonic nozzle having an inlet section which converges to a throat region from which a diverging outlet section extends.  The inlet  section  is  coupled  in  the  fluid  flow path  of  the heat engine at the boiler outlet, while its outlet section is coupled to a downstream condenser.  The working fluid from the evaporator of the heat pump is entrained at a point downstream of the throat region  where  the  pressure  in  the  nozzle  is  lower  than  the pressure  at  the  exit  of  the  evaporator.  The  pressure  of  the second working fluid from the heat pump is lower than that of the exiting fluid (and the input fluid from the heat engine). The two fluids are mixed together and decelerated by the nozzle, causing the  working  fluid  exiting  the  nozzle  to  be  compressed  to  a pressure intermediate that of the heat engine fluid and the heat pump fluid, The working fluid is preferably comprised of at least one fluid compound selected from the group consisting of a carbon disulfide  and  a  bromine  fluid  compound  and  a  phosphorus, phosphoryl  or thiophosphoryl  fluid compound having the  formula PXXX or PZXXX, wherein P corresponds to phosphorus, Z corresponds to one of oxygen (O) and sulfur (S), and X corresponds to one of fluorine (F), chlorine (Cl), bromine (Br) and iodine (I).

Title: Encoding and decoding methods
Inventor: SHIMADA MICHIO
IPC: G09C1/00
Filed: 1989-04-27
Granted: 1994-07-05
Abstract: ABSTRACT             An encoding method for producing a code associated with inputted information comprises several steps.  Firstly, if a numerical representation of the inputted information is smaller than a predetermined numerical value a predetermined operation is applied to the information.  A residual remaining after a result of the operation is divided by the numerical value is produced as an interim result.  If the numerical representation of the in-putted information is not smaller than the numerical value, a predetermined conversion is applied to the information and a result of the conversion is produced as an interim result.  A further step involves applying a predetermined code conversion to the interim result and producing a result of the code conversion as a new interim result.  If the new interim result is smaller than the numerical value, the predetermined operation is applied to the new interim result and a residual remaining after a result of the predetermined operation is divided by the numerical value is produced as the code.  If the new interim result is not smaller than the predetermined numerical value, a predetermined conversion is applied to the new interim result and a result of the conversion is produced as the code.

Filed: 1989-06-12
Granted: 1993-06-08
Abstract: Abstract The  present  invention  relates  to  a  process  for production of  chlorine dioxide  by reacting  in a reaction vessel  an  alkali  metal  chlorate,  sulfuric  acid  and a reducing  agent,  preferably  methanol,  in  proportions to generate chlorine  dioxide in  a reaction medium maintained at a temperature from about  50°C  to  about  100°C  and an acidity within  the interval from 4.8 to 11 N and subjected to a subatmospheric pressure sufficient to  effect evapora-tion  of  water.  A  mixture  of chlorine dioxide and water vapour is  withdrawn  from  an  evaporation  region  in the reaction vessel and alkali metal sulfate is precipitated in a crystallization region in the reaction vessel. The alkali metal sulfate, which is an alkali metal sespuisulfate, from the crystallization  region is  heated to  the formation of gaseous sulfur trioxide and a neutral alkali metal sulfate. The gaseous sulfur trioxide is  absorbed  in  water  to the formation of sulfuric acid. The sulfuric acid formed can be recirculated to the reaction  vessel  for  chlorine dioxide production.

Abstract: Apparatus for spreading fibres uniformly over a forming conveyor has separate fibre distributors (10, 12), These deposit dry fibres onto a conveyor belt (60) which runs through a tunnel (51) into which fibre-dispensing openings of the distributors (10,12) discharge fibres. 
<??>To reduce the likelihood of fibres accumulating on the tunnel walls (50 etc,) and possibly resulting in lumps falling onto the conveyor belt (60), the tunnel has seals (52, 54) at its belt-entrance and belt-exit ends, and beneath-belt suction produced by a suction box (64) is such that air flow into the tunnel through its sealed ends is insignificant. The distributors (10, 12) are contiguously side-by-side, an arrangement which minimizes the suction requirements.

Abstract: The material for extraction is extracted with physiologically acceptable fat or fat-like solvents in the presence of water. This is carried out in a closed pressure vessel at elevated temperature. The amount of water must be such that the water activity corresponds to a aw value of not less than 0.5. By suitable choice of the aw value it is possible to control the process in such a way that the flavour develops in the direction of a boiled flavour or in the direction of a roast flavour. The resulting flavour concentrate can be used as a semi-finished product in the manufacture of sauces, soups, seasoning mixes and the like or can be sold as a finished product. The material which has been subjected to the extraction process is in general completely tasteless.

Abstract: A coupler adaptor (32) is provided for use in operative association with a container (16) and a valve (26). The container houses relatively high pressurised carbon dioxide gas for use in carbonating a beverage. The valve is actuated in order to release the gas to an interface passage (52) formed in the coupler adaptor. The coupler adaptor has a pair of grooves (54, 56) formed on opposite sides of the interface passage for receiving O-rings (58, 60). The coupler adaptor is also in operative association with a pressure regulator (62). The pressurised gas enters the pressure regulator from the coupler adaptor interface passage. The coupler adaptor remains operatively joined to the pressure regulator without retaining structure due to the balanced gas pressure which results because of the O-rings positioned adjacent the coupler adaptor interface passage.

Date May 19, 1988.A cylinder has a roll shell that rotates around a fixed central axis. A first chamber arranged inside the cylinder is filled with liquid and transfers a supporting hydraulic force from the central axis to the shell. The first chamber is linked by a throttle to a second chamber located as well inside the cylinder, and in which is arranged for example a hermetically closed rubber hose filled with gas, so that the second chamber is at all times only partially filled with liquid. Thus, the volume of liquid contained in the second chamber can rapidly change when there is a change of pressure in the first chamber, so when the shell tends to vibrate, liquid flows back and forth through the throttle, converting wave energy into frictional heat by means of fluid friction, and thereby damping the vibration.
