Title: Addressing system for computer memories
Inventor: CERNY VACLAV
IPC: G06F12/04
Filed: 1965-08-23
Abstract: 1,077,028. Computer memory devices. V#YZKUMN#Y U#STAV MATEMATICK#YCH STROJU. Aug. 23, 1965, No. 36065/65. Heading G4C. An addressing system for a computer memory having a word capacity such that data to be stored is stored in two address positions, comprises means for obtaining one of the addresses, means changing the value of that address to obtain the other address and control means to selectively provide the two addresses. As shown in Fig. 2 inputs 12 denoting digits 0 to 9 representing hundreds and inputs 13 I, II, III representing 0, 1 and 2 thousands are connected to sets of AND gates, one set enabled by an input 00, the other set being enabled by input 01. When the address of one half of the data is obtained the address is applied to the inputs. During the 00 cycle the same address is obtained at the outputs 22, 23. During the 01 cycle an alternative address is obtained. For the thousands 0 becomes 4, 1 becomes 3, 2 remains 2. For the hundreds 0 becomes 9, 1 becomes 8, 2 becomes 7 etc. In the embodiment described it was sufficient to only change the address in the hundreds and thousands column and an address range of 0 to 2499 was sufficient for one half of the data. If the total number of words to be stored is, e.g. 2000, 4000, 6000, i.e. the most significant digit is even, then only the most significant digit in the address number is altered, by complementing the most significant digit of the first address with one less than the most significant digit of the total number of words to be stored. For 6000 words a first address 2167 becomes 3167, the 2 being complemented with respect to 5. For an odd most significant digit, e.g. 5000 the most significant digit of the first address is complemented with respect to one less than the most significant total digit and the second most significant digit is complemented with respect to 9. Thus 2167 becomes 2867.

Abstract: 1,069,025. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 26, 1965 [Aug. 27, 1964], No. 36793/65. Heading G6C. The core of a fast reactor comprises elements 1 of fuel or fertile material, those elements comprising an outer blanket 2 containing only fertile material whilst the remaining elements have end portions of fertile material forming top and bottom blankets 3, 4 and central portions of fissile material forming concentric inner and outer core portions 6, 5. The number of elements 1 in the outer core portion 5 is greater, per unit volume of the core, than the number of elements in the inner portion 6 thereby varying the neutron flux to obtain a substantially uniform specific power throughout the core portions 5, 6. Owing to the decreased space available for the upward flow of sodium coolant in the outer core portion 5 the coolant is supplied at a higher pressure to that portion as compared with the pressure of the coolant supplied to the core portion 6 and blanket 2. The coolant leaves the pressure vessel through ducts 30 and passes to neutron traps 31 and heatexchangers 32 (Fig. 4, not shown) whence it is pumped back to the underside of the core through concentric duets 39, 42. The inner duct 39 contains the coolant at the higher pressure and is connected to an annular distributer 41 for cooling the outer core portion 5, the coolant at the lower pressure passing through the outer duct 42.

A device for taking successive samples of a liquid circulating at a constant flow rate comprises an accumulator chamber 1 connected by a pipe 4 to a measuring chamber 2 which communicates, via a pipe 7, with a mixing chamber 3, and a siphon pipe 13 connected to the mixing and accumulator chambers and with atmosphere via a pipe 14 and valve 15, the mixing chamber being connected via a pipe 8, restriction 9, two-way valve 10 and a pipe 11 with a source of vacuum 12 or with atmosphere; the measuring chamber 2 is connected with atmosphere via a pipe 5 and valve 6. In operation, both valves 6 and 15 are closed and the valve 10 operated to connect the system to the vacuum source 12 thereby raising liquid into the measuring chamber and part-way up the pipe 7; the valves 6, 10, 15 are then opened to atmosphere as shown thereby allowing excess liquid in the measuring chamber to flow back to the accumulator 1, the measured quantity left in chamber 2 being determined by the entry position of the pipe 4 into the latter chamber. Valve 15 is then closed and the valve 10 operated to connect the pipes 7, 8 with the vacuum source thereby raising the liquid in the measuring chamber into the mixing chamber 3; the above procedure may be repeated several times in order to fill the chamber 3 with a number of measured quantities. A sample of the liquid in the chamber 3 is then removed from the chamber 3 by means e.g. of a sample withdrawing needle. In order to return the liquid in the chamber 3 back into the accumulator chamber 1, the valves 6, 10 and 15 are actuated in such a way as to produce a pressure differential between the interiors of pipes 8 and 14 thereby causing the liquid to be siphoned, via the pipe 13, back into the chamber 1. The liquid in the chamber 3 may be agitated by compressed air of mechanical means and the valves 6, 10, 15 actuated by a programmed control device.

Abstract: 975,207. Paper-making apparatus. CLARK & VICARIO CORPORATION. Oct. 4, 1962 [Oct. 4, 1961], No. 37573/62. Heading D2A. [Also in Division G3] A method for providing a substantially constant flow of de-aerated aqueous cellulose papermaking stock from a stock de-aerating station 16, comprises maintaining an enclosed stock receiver 1 under substantially reduced pressure, conveying feed stock into the receiver under de-aerating conditions, collecting a pond 19 of de-aerated stock within the receiver, withdrawing the stock from the receiver through conduit 11 at a lesser rate than the feed rate of stock so that excess stock overflows a weir 6 into a chamber 7, and returning stock from the chamber to the receiver at a rate which maintains the level of stock in the chamber within predetermined limits. Stock flows from pump 4 to the receiver 1 via atomizing means which may comprise hydrocyclones 5, which also de-dirt the stock, or nozzles (Figs. 5 and 6 not shown), or just the feed pipes 31. The level of the stock in chamber 7 is kept constant by means of sensing means 17-for example a float or differential pressure cell-which regulate through control instrument 18 and pneumatic or electric means 44 and 45, a valve 21 in the conduit 20 which supplies the recycle stock to pump 4. Alternatively, chamber 7 may communicate directly with pump 4 through a "barometric drop leg". Fresh stock is supplied to pump 4 from white water pit 3 and stock chest 42 through valves (not shown). By regulating a valve 26 in the conduit 25 which feeds the stock to headbox 13 the consistency of the stock is varied, since the amount of stock recycled is correspondingly varied, causing, if the flow of stock from chest 42 is kept constant, an opposite variation in the amount of water reaching pump 4 from pit 3. Conduit 28 with valve 27 may be inserted so as to decrease the volume of recycle pulp passing through pump 15. The weir may take various forms (Fig. 2-4 not shown) in one of which a baffle plate prevents surface scum from being drawn into chamber 7. Specifications 691,000, 755,741 and 755,973 are referred to.
