Date Oct. 13, 1994The subject of the invention is a method for regulating the level of the meniscus (13) of the liquid metal in a mold (5) of a machine for the continuous casting of metals, according to which method the electrical signals supplied by at least one pair of sensors (17, 18) overhanging said meniscus are picked up, said signals being a function of the respective distances (h1, h2) between said sensors and said meniscus, these two signals are combined so as to obtain a single signal representing an imaginary level of said meniscus and said signal is sent to means (15, 24) for controlling a device (14) for regulating the flow rate of metal penetrating the mold, so that said control means actuate said device so as to bring said imaginary level of said meniscus back to a predetermined set value (h), wherein each signal coming from said sensors is conditioned, eliminating therefrom the oscillations having both a frequency greater than a threshold (F) and an amplitude less than a threshold (D). The invention also relates to a mode of combining said signals and a device for implementing said method.

Abstract: The present invention concerns the product produced by inactivating exracellular or intracellular pathogenic virus in a biological composition without incurring substantial disruption or inactivation of cells and without significant loss of labile proteins or other valuable biological components also contained therein, the inactivation process comprising subjecting said composition to a virucidally effective amount of irradiation in the presence of (a) a mixture of a compound that quenches type (I) photodynamic reactions and a compound that quenches type (II) photodynatic reactions of (b) a bifunctional compound that is capable of quenching both type (I) and type (II) reactions, to thereby inactivate said virus while retaining functionality of said composition. The composition is advantageously subjected to the irradiation and the mixture of compounds or bifunctional compound in the presence of an irradiation sensitizer. Moreover, the process can be advantageously combined with a different virucidal method to enhance virus inactivation.

Title: Two-way memory system providing temporary storage
IPC: G11C11/06
Filed: 1970-01-12
Abstract: 1292751 Magnetic storage arrangements SPERRY RAND CORP 12 Jan 1970 [15 Jan 1969] 1401/70 Heading H3B [Also in Division G4] In a two wire magnetic memory system information read out successively from the storage elements along a Y drive/sense line by applying a half select pulse to the Y drive line and successive half select pulses to successive X drive lines coincidently therewith but after a delay-to allow noise in the Y drive/sense line to subside, is stored in a temporary store and then rewritten into the storage elements along the Y drive/sense line. In the embodiment shown in Fig. 1 the Y drive/sense lines are divided into four groups 1Y1-1Y4, 2Y1-2Y4, 3Y1-3Y4 and 4Y1-4Y4 and each group is provided with a temporary storage line 1YT-4YT. In order to read information out of a selected drive/ sense line, e.g. 1Y1, decoder-controller 12, Fig. 5 (not shown), controls bit selector 16 to couple a half-select current 50, Fig. 2, to line 1Y1. After a time interval t r -t 1 to allow the noise signal induced in the 1Y1 line to die down decoder-controller 12 controls word selector WS to couple pulse 52 to line X1 which adds at memory element 1Y1W1, and subtracts at 1Y1W2, with pulse 50 to change the state of memory element 1Y1W1 and induce in the 1Y1 line signals 54 or 56 representative of a "1" or "0" stored. The sense signal 54, or 56 is reflected back into selector 16 which delivers an output signal at 18 and concurrently generates a delayed restore signal 64 or 66 on temporary storage line 1YT at time t 2 . Simultaneously at time t 2  pulse 58 is applied to word line X1 to switch core 1Y1W2 and so induce output 60, 62 in the 1Y1 line and with restore signal 64, 66 set temporary storage element 1YTW1 into the appropriate state. At time t 3  pulse 70 is applied to word line XI which coincidently with restore pulses 72, 74 produced by signals 64, 66 switch core 1YTW2. Pulses 52a, 58a, 70a are then applied to word line X2, X3 &c. in succession to read out all the information stored in line Y1 and store it in temporary storage line 1YT. Following the read cycle the information is read out from temporary storage line 1YT and written into line 1Y1 in a similar manner, in this case a half select pulse is applied to line 1YT and not line 1Y1. Corresponding Y lines in each group are read simultaneously to give parallel outputs at 18, 19, 20, 21 each output representing one bit of a 4-bit word. Instead of employing the temporary storage lines YT the matrix and temporary store may be physically separate, Figs. 7, 8 (not shown), and in the latter Fig. the temporary store is an integrated circuit thereby enabling the cycle to be faster than when both stores are of toroidal cores.

Abstract: A linear polyester is obtained by polymerising a carboxylic acid of formula :  <FORM:0847767/IV(a)/1> where R is a linear or branched saturated or unsaturated carbon chain which may be interrupted by hetero atoms and/or cyclic systems, or is a cyclic system, and n is 0, 1 or 2. Polymerisation is effected by heating to 50 DEG -130 DEG C in the presence of a Friedel-Crafts catalyst or an acid condensing agent (e.g. boron fluoride or its etherate, tin tetrachloride or its etherate, tin tetrabromide, zinc chloride, aluminium chloride or concentrated sulphuric acid).  Specified carboxylic acids are the maleic and phthalic acid half-esters of endomethylene tetrahydrobenzyl alcohol and the maleic acid half-ester of endomethylene - 1,2,3,4,4a,5,8,8a-octahydronaphthalene.  The polyesters are soluble in benzene, toluene, pyridine, ethanol and chloroform.  Those polyesters containing ethylenic unsaturation may be copolymerised with another ethylenically unsaturated compound, e.g. styrene methyl methacrylate or diallyl phthalate, if desired in the presence of a catalyst (e.g. benzoyl peroxide or cyclohexanone peroxide) and an accelerator (e.g. cobalt naphthenate).ALSO:Examples describe the preparation of the following half-esters:-(1) The half-ester of endomethylene tetrahydrobenzyl alcohol and maleic acid is made by heating the alcohol with maleic anhydride at 50 DEG  C.; (4) The half-ester of 2-hydroxymethyl - 1,4,5,8,-bis-endomethylene1,2,3,4,4a,5,8, 8aoctahydronaphthalene and maleic acid is made by heating the alcohol with maleic anhydride at 60 DEG  C.; (5) The half-ester of endomethylene tetrahydrobenzyl alcohol and phthalic acid is made by heating the alcohol with phthalic anhydride at 180 DEG  C.  The half-esters are polymerised to form polyesters (see Group IV(a)).
