Title: O-carbamyl-d-serine and process for its production
IPC: C07C271/06
Filed: 1955-07-08
Abstract: O - carbamyl - D - serine <FORM:0775946/IV(b)/1> is produced by the fermentation of Streptomyces polychromogenus nov. spec. NCIB 8791 and T. 4473 (French Culture Collection), or a mutant thereof, in an aqueous nutrient medium containing a source of nitrogen, carbon and mineral salts, at a pH of 6 to 8.5 under conditions of submerged or surface culture.  The temperature of fermentation is 20-32 DEG  C., the duration e.g. 50 hours.  A preferred medium contains deoiled soya bean flour 2.4 to 2.8 per cent, dextrin 0.9 to 1.1 per cent, glucose 0.9 to 1.1 per cent, magnesium sulphate 0.25 to 0.35 per cent and calcium carbonate 0.15 to 0.25 per cent.  O-carbamyl-D-serine is recovered from the clarified broth by adsorption on a sulphonic acid type ion exchanger in the acid form, e.g. Amberlite IR120 (Registered Trade Mark), Diwex 50 or Permutit 9 (Registered Trade Mark) and elution therefrom with a weak base, e.g. an aqueous solution of ammonia, pyridine, triethylamine or tributylamine.  Further purification is obtained by treatment of an aqueous solution with charcoal and recrystallization from aqueous organic solutions, e.g. aqueous methanol.  The mono-2,4-dinitrophenyl derivative of O-carbamyl-D-serine is prepared by adding a solution of 2,4-dinitrofluorobenzene in ethanol to a solution of O-carbamyl-D-serine in aqueous sodium carbonate.  A copper complex is produced by heating O-carbamyl-D-serine with freshly precipitated copper carbonate.  O-carbamyl-D-serine is active against virus infections in animals and in humans; it is soluble in dilute hydrochloric acid and in hot water sparingly soluble in methanol and ethanol.  Details are given of the characteristics which enabled the constitution of the antibiotic to be established.

Title: Method of producing metal hydrides containing boron
IPC: C01B6/00
Filed: 1955-07-13
Abstract: <PICT:0810726/III/1> Borohydrides of metals, which form salt-like hydrides, e.g. alkali metals, are produced in a two-stage process wherein, in the first stage, boron halide is reacted with a metal borohydride to form diborane, which is reacted, in the second stage, with the hydride of the same metal to form metal borohydride, part of which is used for the production of diborane in the first stage.  A solution of lithium borohydride in ether in vessel 1, equipped with an agitator, is reacted with boron trifluoride etherate, while scavenging gas may be introduced.  The diborane formed passes through reflux to vessel 2 containing a suspension of lithium hydride in ether.  One third more diborane than is required to react with all the lithium hydride in vessel 2 is produced from vessel 1 and the remainder passes on to vessel 3.  Boron trifluoride is then reacted with the lithium borohydride in vessel 2 to form diborane, which passes into vessels 3 and 4, and so on. As a result 1/4 of the lithium borohydride produced is recovered, while the other 3/4 is used in the preparation of diborane.  An alternative apparatus (Fig. 2, not shown) shows a process with a closed cycle of units working on the above basis. It is stated that to start the reaction boron halide may be reacted with lithium hydride in vessel 1, and diborane from other sources may be added during the process.

Filed: 1975-05-14
Abstract: 1491357 Electronic counters WESTERN ELECTRIC CO Inc 14 May 1975 [16 May 1974] 20339/75 Heading G4A [Also in Division H1] A charge-coupled binary counter for counting up to 2n-1 signal pulses includes, in a semiconductor substrate 10, a charge-coupled "quantizer" 12 for providing a predetermined quantity of charge in response to each signal pulse, a sequence of n charge-coupled "threshold cells" 14À1, 16À1, 18À1 the first of which receives charge from the quantizer, each threshold cell 14.1 &c. having at its input a first potential barrier (e.g. 12.5) such that substantially all charge will transfer into that threshold cell from a preceding cell on suitable energization of the electrodes and having at its output a second potential barrier (e.g. 14.3) of greater height than the first barrier such that charge is transferable across the second barrier only when two of said predetermined quantities of charge are in that cell and, for at least the first n-1 of the n threshold cells, feedback means responsive to charge transferred across the second barrier for removing residual charge remaining in that cell. In the illustrated counter n = 3, there being three charge-coupled threshold cells 14.1, 16.1, 18.1 at least the first two of which are followed in the counter sequence by charge-coupled transfer cells 14.2, 16.2. The quantizer 12 comprises two charge-coupled cells 12.1, 12.2, the cell 12.1 being supplied with charge by an input diode 11. The first (dot-dashed) and second (double dotdashed) potential barriers, as well as charstop barriers such as 12.7, 8 defining the lateral edges of the devices, may be formed as diffused or implanted elongate strips. The feedback means associated with each of the first two thresholds cells of the counter include, in addition to the associated transfer cell (e.g. 14.2), a grounded source IGFET 17 which is open-circuited by the presence of charge in the transfer cell 14.2. As a result a charge-coupled "dump gate" 15 connected to the threshold cell 14.1 is opened to drain residual charge from the cell 14.1, resetting the cell to the "0" state while the next cell 16.1 switches to the "1" state as a result of the transfer of charge thereto from the preceding transfer cell 14.2. All the dump gates 15 can be simultaneously opened by a "read control" signal from IGFET 111, so as to dump the storage charges across loads (e.g. 20) via charge-sensing IGFETs 19, 21, 23 to permit read-out.
