Abstract: CRYOGENIC RECONDENSER WITH REMOTE COLD BOX                      Abstract A recondenser cycles a working volume of cryogen gas through a remote cold box and a coaxial recondensing, heat exchanger transfer line which is inserted into a cryostat.  The working volume of gas is compressed to a high pressure and cooled through cooling means which include a mechanical refrigera-tor of the regenerator-displacer type.  The cooled gas is expanded through a first JT valve to a medium pressure and further cooled.  The further cooled medium pressure gas is transferred in a closed coaxial transfer line to a cryostat in which boil-off is recondensed.  A second JT valve in the cryostat end of an inner tube coaxially positioned in an outer tube forming the transfer line expands the gas to a lower pressure and forms a liquid-gas mixture.  The liquid-gas mixture is passed in heat exchange relation with the boil-off from an inner tube to an outer tube of a coaxial recondensing heat exchanger.  The outer surface of the outer tube at the cryostat end of the transfer line has burrs which provide the necessary surface area on which to recondense the boil-off.  The gas is transferred back to the cooling means through intermediate channels formed between the outer tube and the coaxially positioned inner tube.

Abstract: EDIBLE GELS                          A B S T R A C T            Thermo-irreversible aqueous gels are prepared by subjecting a gellable combination of xanthan gum and a glucomannan gum, preferably from the corms of an Amorphophallus species at a pH above 6 to a heat treatment under conditions of temperature and time to cause the gel to become thermo irreversible. The pH is preferably between 6 and 10 and more especially between 6 and 8.  The preferred ratio of xanthan gum to glucomannan is in the range of from 5:95 to 95:5, more especially 1:10 to 10:1 and the preferred concentration of xanthan gum and glucomannan in the aqueous phase is 0.02% to 6%, more preferably .5 to 4%, by weight.  The thermo irreversible gels of the invention, with the inclusion of food materials, such as minced meat, fruit and vegetables, simulate the texture of natural meat offals and other food structures.

Abstract: ABSTRACT    A fault tolerant computer system includes a fault tolerant data processing module which has means for detecting and cor-recting errors in the operation of the data processing module to maintain a high degree of data integrity.  Data transmission con-trol devices control the transmission of all data to the fault tolerant data processing module and the receipt of all data into the fault tolerant data processing module.  Input/output termi-nals are coupled to the data transmission control means for receiving and transmitting data.  A non-fault tolerant input/output module is coupled to transmit the data to the input/output terminals of the fault tolerant data processing module.  This module includes a read device for transferring data to the fault tolerant computing system in response to requests from the data transmission control devices, and a firewell for preventing the non-fault tolerant input/output module from initiating transfers of data to the fault tolerant data pro-cessing module.

Title: Radiating coaxial cable with improved flame retardancy
Inventor: RAMPALLI SITARAM
IPC: H01B11/18
Filed: 1988-09-09
Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE     A radiating cable of the foam dielectric type is provided with increased flame-retardant capabilities by provision of an inert barrier tape between an apertured, corrugated outer conductor and the external jacket surrounding the conductor.          The barrier tape is composed of non-halogenated, self-extinguishing insulating material and is wrapped over the outer conductor in such a way as to completely cover the radiating apertures disposed thereupon.  The barrier tape prevents the melting and bubbling of the dielectric foam outwardly through the radiating slots into penetrating contact with the external jacket when the cable is subjected to high-intensity flames, without significantly affecting the transmission characteristics of the cable.

Abstract: ABSTRACT    A hermetic compressor assembly is disclosed including a compressor mechanism and an electric drive motor within a hermetically sealed housing.  The electric motor includes a rotatable rotor and a stator.  In one disclosed embodiment, the stator is friction fit within the housing and the rotor is press fit over a crankshaft journalled in a crankcase of the compressor mechanism.  The crankcase is selectively positioned within the housing and mounted thereto by means of mounting pins.  In another disclosed embodiment, the motor is mounted to the compressor mechanism and the compressor crankcase is axially supported in the housing.  A mounting pin is used to prevent rotation of the compressor mechanism within the housing caused by torque forces produced by dynamic operation of the motor.  The disclosed mounting pins are received within holes in the crankcase and extend radially outwardly through oversized apertures in the housing.  The pins are selectively positioned in the apertures prior to welding.  A method of assembling a compressor having mounting pins is also disclosed.

Abstract: An encapsulation method is disclosed.  The method provides a means of encapsulating biological material  such  as  proteins  and  microbes.   In  one aspect, the method provides a means of using microbes as agricultural agents since the microbes can now be put into a formulation that is acceptable and useful to  the  farmer.   Briefly,  the method employs water-soluble polymers at concentrations  greater than 3% (w/v) to which is added the biological material.  The mixture  is  then  freeze-dried  thereby  producing  a stable  encapsulated  product which  in  the  case  of microbes retains a high level of viability.
