Title: Microbial co-culture production of propionic acid
Inventor: MAYS THOMAS D
IPC: C12N1/20
Filed: 1985-12-05
Granted: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE    A simultaneous sequential anaerobic fermentation process for the in vitro production of propionic acid and acetic acid is disclosed.  The process comprises employing an obligatory two-component co-culture which maintains a relatively constant ratio of species populations over multiple passages.  A first co-culture component is a Lactobacillus or Streptococcus which homofermentatively converts the hexose to lactic acid.  A second microorganism in the co-culture is a Veillonella which is metabolically incapable of assimilating the hexose and converts the lactic acid product to propionic acid and acetic acid.  The co-culture is inoculated into a nutrient growth feedstock, such as whole whey or a clarified dairy whey lactose permeate, which contains a metabolizable source of a hexose, such as glucose. lactose or sucrose.

Abstract: ABSTRACT                  MANUFACTURING VITREOUS BEADS      A process of manufacturing vitreous beads is disclosed in which feedstock particles of a glass-former composition containing chemically bound water. are fed through a heating zone in which the particles are vitrified and spherulized and the resulting vitreous beads are cooled. The size of the feedstock particles and their content of substance which becomes gaseous during the passage of the particles through said heating zone are such that at least 20% by weight of the formed beads have a relative density greater than 1Ø  The vitrifiable oxide forming elements of said glass-former composition may be chemically interlinked. and the feedstock may by prepared as a silica-based gel or precipitate having a composition suitable for vitrification into a glass of any desired composition for example one which by virtue of its low alkali content is resistant to hydrolytic attack.  By control of the cellulating agent content (bound water and optionally a gas evolving salt radical such as nitrate or sulphate) of the feedstock, and its granulometry, the relative proportions of solid and hollow beads which will be produced in a given spherulizing run can be controlled.

Title: Vessel for the generation of synthesis gas
Inventor: HERBORT HANS-JOACHIM
IPC: B01J8/06
Filed: 1986-09-10
Granted: 1992-10-06
Abstract: ABSTRACT          The invention relates to a vessel for the generation of synthesis gas at a high pressure, using hydrocarbons, particularly natural gas, nahptha and/or refinery gas in a catalytic endothermic reform-ing section with a plurality of reformer tubes heated externally and filled with a catalyst, a mixture of hydrocarbons and steam en-tering the reformer tubes positioned by a common plate. The reform-ing gas generated in said tubes flows from the tubed section into the partial oxidation section which has a larger diameter than the tubed section and the shape of a pressure vessel closed at one end, the free ends of the reformer tubes penetrating into said section, and in which additional hydrocarbons and oxygen or oxygen-rich gas are mixed with the reforming gas. The aim is to design a vessel suitable for the required thermal reactions, to provide reliable operation of the vessel and to ensure complete reactions. This aim is achieved by installing a plurality of inlet devices for hydro-carbons and/or oxygen or oxygen-rich gas in the cylindrical shell of the partial oxidation section, the centre-lines of said devices being parallel to or inclined towards the radial streams, which form a plane, and said devices being spaced at a certain distance from the outlet end of the reformer tubes such that a rotary gas vortex is produced and that the product gas stream flows through the outer section of the chamber, heats the reformer tubes and leaves the reforming section via the outlet nozzle.

Title: Reaction mechanism for brake booster
Inventor: MYERS LAWRENCE R
IPC: B60T13/563
Filed: 1986-11-26
Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE A reaction mechanism for use in a vacuum brake booster (10).  A lever (86) transfers a reaction force from a first plunger (64) into a second plunger (110) to provide an operator with an indication of the output force being produced in response to an input force.  A resilient member (118) urges a first connecting member (116) into engagement with the lever (86).  When a predetermined input force is applied, the reaction force overcomes the resilient member (118) and thereafter allows the input force to be directly transmitted through a second connecting member (122) and added to the output force.

Abstract: To provide for the rapid vaporization of a liquid, a porous body is impregnated with the liquid. Then the liquid contained in the porous body is heated, so as to cause a rapid vaporization of the liquid in the porous body which liquid continually migrates through the porous body under the effect of its pumping and suction capabilities. The whole of the mass of liquid to be vaporized is stored in the body in impregnated form, without the presence of a permanent liquid layer. The liquid is heated directly by passing an electric current through the porous body, the density of the porous body being chosen so as to provide a liquid retention capacity allowing a variation of the energy dissipated in time to be obtained in accordance with a predetermined law which is a function of the density chosen for the porous body. Thus interchangeable porous bodies can be used having different densities and allowing different curves of variation of the energy dissipated in time to be obtained, respectively. To provide for operation in any position the liquid is introduced and stored in a liquid mass to be vaporized solely in impregnated form directly inside the porous body, without formation of a permanent liquid layer in a housing for the porous body.

Abstract: ABSTRACT OF THE DISCLOSURE          An airborne surveillance method and system allows an observer aircraft to determine the position and change of position of a multiplicity of target aircraft and thus allows analysis of collision threats from these aircraft. The  system  uses  a  phase  comparison  direction  finding antenna to determine direction of nearby ground based SSRs and all target aircraft of interest.   The system further makes use of  all  other  available data  including Mode C transponder  generated  altitude  information of  the  target aircraft,  the  altitude  of  the  observer  aircraft,  the received  signal  strength  of  both  the  SSR  beam  and  the received transponder signal, the time difference of arrival between the SSR interrogation signal and the response from the  target  aircraft,  and  a  variety of  other  factors  to determine the position of the target aircraft.  The system compensates for the attitude of the observer aircraft and performs optimal Kalman filtering on the input data set to produce  an estimate  on target  position based upon prior estimates and upon information contained in the data set while  making  estimates  of  the  error  magnitude  of  each measurement  and  compensating  for  these  errors.    The covariance  matrix  Q  of  the Kalman  filter  is  adaptively varied so as to optimize  the  estimate  of  the degree of correlation between various input values.
