Title: Method for producing cephalosporin c
IPC: C12P35/06
Filed: 1972-11-15
Abstract: 1389714 Producing cephalosporin C and helvolic acid TAKEDA YAKUHIN KOGYO KK 15 Nov 1972 [15 Nov 1971] 52741/72 Headings C2C and C2U Cephalosporin C and helvolic acid are produced by aerobically cultivating the new microorganism Cephalosporin polyaleurum or a cephalosporin C- and/or helvolic acid-producing mutant or variant thereof in an aqueous nutrient medium and recovering cephalosporin C and/or helvolic acid from the culture broth. The preferred micro-organisms are Cephalosporin polyaleurum 199 (ATCC. 20359, FERM-P No. 1159) and a mutant thereof referred to as Cephalosporin polyaleurum Y-505 (ATCC. 20360, FERMP No. 1160) produced by ultra-violet irradiation of the original organism. Both micro-organisms produce cephalosporin C and hevolic acid together with a small amount of penicillin N. The cultivation is preferably conducted under submerged aerobic conditions in a conventional liquid culture medium. The antibiotics are produced extra-cellularly, and are isolated by filtering off the mycelium, bringing the filtrate to pH 5 and extracting it with ethyl- or butylacetate which takes out the helvolic acid. The aqueous phase is worked up by adsorption on activated carbon, elution with aqueous acetone, concentration of the eluate, absorption on weakly basic ion-exchange resin, elution with ammonium acetate/acetic acid buffer, concentration and after neutralizing with NaOH, precipitating cephalosporin C as the sodium salt by adding acetone. The helvolic acid is obtained from the ethyl- or butylacetate extract of the broth filtrate by concentrating, absorbing on silica gel, eluting with chloroform and evaporating the latter solvent. The examples include for purposes of comparison, a process for producing cephalosporin C by cultivating Cephalosporeum acremonium (ATCC. 14,553).

Title: Cooling system for nuclear reactors
Inventor: BOHDANSKY JOSEF
IPC: G21D7/04
Filed: 1965-12-13
Abstract: 1,108,499. Reactors. EUROPEAN ATOM ENERGY COMMUNITY (EURATOM). 13 Dec., 1965 [14 Dec., 1964], No. 52862/65. Heading G6C. A nuclear reactor has one or more heat pipes as a means for extracting the heat of reaction. A heat pipe is a heat transfer device comprising a container, condensable vapour, and capillary means disposed within the container for the transport of the condensed vapour from a cooler region of the container to a hotter region. The vapour is driven from the hotter region to the cooler region by the difference in vapour pressure. The temperature drop along the heat pipe is powers of ten lower than in the case of conventional heat transports and a nearly uniform temperature distribution is therefore established along the entire pipe surface. In a specific example, portions of heat pipes are disposed in, and thermally coupled to, passageways in the fuel elements, moderator and reflector of a reactor core to form evaporator regions, the non-coupled portions extending outwardly from the reactor core to form condenser regions. The inner walls of the heat pipes are covered with wicks, e.g. of niobium, of suitable capillary structure, the pores sizes of the wicks being sufficiently small to produce capillary action. Tubular fuel elements may be separately mounted on the heat pipes or the fuel may be coated directly on the outer surfaces of the heat pipes. A suitable fuel is a Mo-UO 2 , cermet. The fuel heat pipes are preferably of Ta and contain Ag as the heat carrier fluid, operating at a temperature of about 1800‹ C., while the moderator and reflector heat pipes are preferably of Nb and contain Cs as the heat carrier fluid. The moderator is ZrH 2  and is separated from the fuel elements by electrical insulation and thermal shields. The condenser regions of the fuel heat pipes each terminate in an emitter electrode of a thermionic converter. The front faces of the heat pipes can each directly constitute an emitter electrode or be vapour-plated with an electron emissive layer. The collector electrodes of the thermionic converter are each coupled to a heat pipe for the removal of heat generated. The collector heat pipes are preferably formed of Nb- Zr alloy and contain Li as the heat carrier fluid.

Abstract: 1447627 First in-first out buffer store CABLE & WIRELESS Ltd 6 Dec 1973 [11 Dec 1972] 57074/72 Heading G4C A buffer store comprises a plurality of recirculating data storage channels storing respective bits of a circulating character, a recirculating index bit channel storing an index bit for each stored character and circulating the index bits in synchronism with the characters, and gating means to permit a character to be entered at the input, and extracted at the output of the data storage channels only in response to transistions in signal level, in respective opposite senses, at the output of the index channel. The data storage SR1-5 and index channels may be shift registers, magnetic disc or drum tracks or a magnetic tape loop. The stored data and index bits are circulated via gates G1B-G1B normally enabled by a gate G5. Gates G4 and G3, by monitoring the current true and inverse outputs of the index channel and the outputs of flip-flop FF1 which represent the previous true and inverse outputs of the index channel, detect 1-0 and 0-1 transitions in the index signal level and generate write and read enable signals which ensure that only the "oldest" stored character can be read out and that a "new" character is written into the store at the location following the "newest" stored character.  In a modification, Fig. 2 (not shown), each channel is connected to a flip-flop providing an additional bit of storage in the channel. A gate monitors the input and output of the index channel flip-flop to determine when the flipflops contain the "newest" character in the store. The "newest" character may then be erased by clearing the flip-flops via a further gate enabled by the monitoring gate. In this way an erroneous character may be erased and rewritten. Further gating circuits are described for preventing the store from becoming full and for inserting a bit into the index register to allow read in to the store when it is empty. The store is said to be of use in telegraphy, the "start" signal associated with each character providing the index bit.
