IPC: C12M1/36
Filed: 1968-01-23
Abstract: 1,153,114. Amino acids; nucleosides by regulated fermentation. AJINOMOTO CO. Inc. 23 Jan., 1968 [6 Feb., 1967], No. 3612/68. Heading C2C. [Also in Divisions C6 and C7] A fermentation process involves culturing micro-organisms in a culture medium in a closed system, removing from the closed system carbon dioxide produced during the process, agitating the culture medium and feeding oxygen to the closed system at a desired controlled rate. A measurement of the partial pressure of oxygen in the liquid or gas phases within the system may be used for on-off control of an electrolytic cell providing oxygen, or of an oxygen cylinder. Alternatively, the amount of oxygen produced by an electrolytic cell 21, Fig. 3, operated under constant voltage potential may be regulated by the variation in level of the electrolyte 21 in the region of the electrode 20 produced by changes in the partial pressure of oxygen in the gas phase of the closed fermenter 1. In this embodiment the oxygen analyser 17 and recorder 18 do not participate in the control action. Carbon dioxide produced is removed by continuously circulating the gaseous phase through a solution of sodium or potassium hydroxide in a washing bottle 6. The fermenter itself may be agitated. Examples relate to the production of L- glutamic acid by cultivation of Corynebacterium acetoacidophilum ATCC 13870 on a specified glucose-containing culture medium in which a dissolved oxygen content of 0À05 atm. at 31.5‹ C. was maintained, as by periodic actuation of a 1 1. capacity electrolytic cell connected to a direct current stabilized power source of 5-15 volts; the production of 5-amino-4-imidazolecarboxamide-riboside by cultivation of Bacillus megaterium ATCC 15117 on a specified culture medium containing glucose and ribonucleic acid (dissolved oxygen=0À02 atm. at 34‹ C.); the production of inosine by cultivation of Bacillus subtilis ATCC 13952 on a specified culture medium containing glucose and adenine (dissolved oxygen=0À06 atm. at 31‹ C.); and the production of L-glutamic acid by cultivation of Corynebacterium hydrocarboclastus ATCC 15110 on specified n-alkane containing culture media (dissolved oxygen partial pressure=0À06 atm. or partial pressure of oxygen in the gas phase= 0À6 atm. at 30‹ C.).

Title: Improvements in or relating to fuel elements for nuclear reactors
Inventor: MEREDITH KEITH EDWARD GEORGE
IPC: G21C21/12
Filed: 1963-01-29
Abstract: 1,071,411. Forging. CENTRAL ELECTRICITY GENERATING BOARD. Jan. 29, 1964 [Jan. 29, 1963], No. 3694/63. Heading B3H. [Also in Division G6] A nuclear reactor fuel element is formed by completely enclosing a rigid rod of fissile material in an integral can. The enclosing is carried out in a die by means of a high-speed, highenergy process, utilizing for example high or low explosives, electro-hydraulic or electromagnetic discharge, or a stored energy pneumatic process. The fuel rod may be solid, e.g. uranium, or composted powder. The canning is preferably a magnesium alloy, but a composite canning billet may be employed to give different properties along the can; the wall thickness may also be varied. The can may also be powdered metal, composted either before or during the coming process. The canning material may be preheated, before or after being placed in the die. Referring to Fig. 1, the billet 12 is placed in the die 10 and the fuel rod 11 and former 14 forced into the billet and die respectively, thus totally enclosing the rod as seen in Fig. 2. The grooves 17 are to prevent ratchetting; the combination of the forming pressure and temperature difference (hot canning billet) results in excellent heat transfer across the interface. Canning may be carried out in a vacuum, or non-oxidizing atmosphere. The die may include longitudinal recesses for forming baffles and splitters (e.g. 26 in Fig. 8, not shown). Fig. 7 shows a fuel element machined from Fig. 2 and including a stabilizing spider 23, the fins may alternatively be of herring-bone pattern. In an alternative method of canning (Fig. 3, not shown), a tubular billet of canning metal is placed in a die having both ends open, and a clearance fit fuel rod placed in it; formers are forced into both ends of the die simultaneously. Helium gas, or a radioactive clathrate compound can be included in the can for leak detection purposes.

Title: Fuel injection systems
IPC: F02D9/00
Filed: 1973-01-25
Abstract: 1411051 Regulating I C engine fuel supply ROBERT BOSCH GmbH 25 Jan 1973 [26 Jan 1972] 3831/73 Addition to 1395526 Heading F1B A fuel injection system for mixture compressing I.C. engines having continuous injection into the intake manifold and separate ignition as claimed in claim 1 of Specification 1395526 is modified in that the electromagnet of the pressure regulating valve consists of a permanent magnet with a moving coil armature. The air-flow into the induction pipe 1, 4, 5 of an engine displaces a measuring element 2, mounted on a pivoted arm 8, which causes sliding movement of a valve spool 11 of a metering valve 7. The spool movement is opposed by the pressure of fuel in a chamber 33, which encloses the end-face 12 of the spool. The pressure in the chamber 33 is controlled by a regulating valve 36, which is connected to the chamber by a passage 35. The regulating valve consists of a valve seat 40 which co-operates with a diaphragm 24 to control the flow of fuel from the passage 35 to a drain line 37. The diaphragm is biased towards the valve seat by a leaf-spring 46 which acts through an intermediate member 45. The leafspring also acts as a mounting for an armature 47 which carries a coil 48. The magnetic circuit associated with the armature consists of a soft iron ring 49, a ring-shaped permanent magnet 50 and a soft iron plate 51 having a core 52 which projects into the armature. When current flows in the coil 48, the armature tends to move in a direction to open the valve 40, 24 against the bias of the leaf-spring 46. The magnitude of the current flow in the coil is determined by an oxygen probe in the exhaust system of the engine. The electrical signal produced by the probe is compared with a reference voltage in a transistorized amplifier circuit and produces a current flow in the coil 48 which opens the valve 40, 24, reduces the pressure in the chamber 33 and enriches the mixture to stoichiometric, the measuring element 2 being adjusted to provide a basic lean mixture. As the driver controlled throttle valve (not shown) approaches the full throttle position an electrical switch is closed which increases the current flowing in the coil 48 to provide a rich mixture for full throttle operation of the engine.

Title: A process for polymerising olefinically unsaturated compounds in a two-phase system and the resulting polymers
IPC: C08F2/22
Filed: 1952-02-19
Abstract: Olefinically unsaturated compounds are polymerized in a two-phase system comprising a continuous phase, which is a solution of an emulsifier in water and the compound(s) to be polymerized as a discontinuous phase, the discontinuous phase being passed in a gaseous state through the water phase in a stream of bubbles of such size that when they rise not more than 25 per cent of the content is absorbed by the water phase. Preferably when the monomer bubbles rise not more than 10 per cent of the content thereof is absorbed in the water phase, and the motion of the monomer bubbles in relation to the water phase is principally caused by the difference in specific gravity of the two phases.  The process is suitable for the polymerization of ethylene, propylene, and vinyl chloride and for the production of copolymers thereof with each other and/or with vinylidene chloride, allyl chloride, styrene and acrylonitrile.  The aqueous phase may contain sodium mersolate, potassium persulphate, hydrogen peroxide and sodium bicarbonate.  The monomer phase may be continuously circulated and a polymer suspension may be produced continuously by continually adding fresh water phase and by withdrawing part of the water phase.  Specifications 687,984 and 707,117 are referred to.
