A water-cooled reactor has vertical passages for delivery of coolant to a plenum chamber below the reactor core, said passages extending through a chamber defined by the core and the reactor vessel walls, the cross-section of the passages being small compared with said chamber. The boiling water reactor described includes a baffle 13 containing fuel tubes 12 through which a primary coolant circulates, and is surrounded by a water-filled reflecting region 24 and a pressurizer chamber 29. A steam separator 46 passes steam through an outlet 43, and heated water through an outlet 47. Pressurizer 38 is connected to primary coolant feed pumps 37. A mixture of cold feed water and recirculated hot water enters the pressure vessel at 48 and passes through holes 51 into an annular chamber 49. The vertical passages 25 carry coolant from the chamber 49 to the inlet plenum chamber 23. A small amount of water flows from the chamber 29 through holes 52 and 14 to the inlet plenum chamber 23. By using a small flow cross-section compared with the cross-sections of chambers 29 and 24, re-circulation time of the hot water is reduced by approximately 30%, resulting in improved power level control stability.

Abstract: 1351404 Automatic exchange systems SIEMENS AG 1 Feb 1972 [19 April 1971] 4558/72 Heading H4K A stored program controlled telecommunication exchange includes incoming and outgoing link supervision units, the incoming unit being arranged upon detection of a connection request to transmit that request and the address of the link making the request towards a communication control unit, the address being stored in a first store in a compartment permanently associated with the link making the request, compared with the address in a second store of the last unit to make a request, and assuming non-identity transferred from the first store to the second to replace the address in the latter, in the event of identity the input to the second store being blocked and the address in the store compared with the address of the link currently making a request, detection of identity between these last named addresses causing the transmission of the current address towards the communication control unit to be blocked and the incoming link supervision unit to step to the next address. As described each incoming link includes a "line adapter" which makes the connection request upon detection of a polarity change on that link. The adapter makes a continuous request until a vacant time slot in a T.D.M. storage connection cycle is allotted to the request. The invention deals with the problem that arises if an adapter fails to cancel the request. If an address received by the incoming link supervision unit and monitored by the circuitry described above persists for the two comparison periods transmission of that request to the communication control unit is blocked and the incoming link supervision unit stepped to the next address stored in the incoming link supervision unit. The address of a faulty line adapter may be displayed on a visual display.

Filed: 1917-03-29
Abstract: 106,088. Rothenbach, W. April 15, 1916, [Convention date]. Tars &c., distilling; progressive evaporators. -The lighter fractions of tar and other liquids are distilled under high vacuum and the heavier fractions under a higher pressure, e.g. a low vacuum or atmospheric pressure. The distilling- columns or retorts are heated either by a single current of steam, direct or indirect, or by products of combustion, flowing in the opposite direction to the liquid under treatment. An apparatus used for distilling tar consists of two columns 2, 5 comprising distilling-elements II and Heating-elements III. Each column is divided into two stills, each of which is formed with dephlegmators I, IV at the top. The vapours generated in the four stills pass to condensers 3, 4, 6, 7 having barometric legs of such lengths that the separate fractions are distilled under successively decreasing vacua. The. condensers 4, 6, 7 also serve as preheaters. The hot pitch from the base of the column 5 is used for reheating the steam from the top of the column 5 before it is passed to the column 2, and afterwards is used to preheat the water of condensation from the top of the column 2 before it is returned to the steam generator.

Title: Improved method for the extraction of casein from seeds
IPC: A23J1/14
Filed: 1944-03-16
Abstract: Casein is extracted from seeds by treating them with a solution containing an alkaline reagent, water and less than 40 per cent by volume of an organic solvent which is soluble in water to at least an extent of 7.5 grams in a 100 c.c. at 20 DEG  C., the solution being separated from the undissolved residue.  The seeds which may be decorticated or undecorticated are preferably used as oil-free meal and the extraction may be carried out at atmospheric temperature or slightly above.  In the examples: (1) oil-free earth nut meal is agitated with water and ammonium hydroxide, acetone added and the agitation continued.  The product is centrifuged to remove solid residue; (2) a similar process is carried out using oil-free soya bean meal; (3) the process of example (2) is repeated using ethyl alcohol in place of acetone; (4) oil-free arachis meal is agitated with aqueous caustic soda solution, acetone added and the agitation continued, the product being centrifuged; (5) a similar process to example (1) is carried out, a little phenol being added to the resulting solution and the mixture heated and stirred.  On cooling and recentrifuging, a spinnable solution is obtained.  The viscosity may be increased if required by removal of solvent by evaporation or reduction of the alkalinity.  Filaments are obtained from such solutions by extrusion through a metal jet into a bath containing sulphuric acid and sodium sulphate.  The fibre may be hardened by any known process.  Other solvents which may be used in the process are stated to be other monohydric alcohols such as isobutyl, isopropyl, allyl and methallyl, diacetone alcohol, acetonyl acetone, esters such as ethyl lactate and ethyl formate, and ethylene glycol.  Alkaline substances which may be used are stated to be sodium hydrate, sodium carbonate, sodium silicate, borax, ammonium hydrate and organic amines such as triethanolamine.  The extract obtained by this process may be used for the preparation of casein paints.  Specifications 492,599 and 492,600 are referred to.
