Patent GB-910980-A (GB)
Title: Preparation of inosine
IPC: C07H1/08
Filed: 1961-01-13
Abstract: In the preparation of inosine by deamination of adenosine with nitrous acid, the nitrous acid is formed in situ from an inorganic or organic nitrite, the pH is at least 1.5, preferably 1.9 to 4.0, and an excess of nitrous acid is used, e.g. 10 to 20 mols of nitrous acid per mol of adenosine.  Barium nitrite may be used, in which case it is reacted with sulphuric acid and the precipitate removed, or ethyl nitrite may be used.  Nitric acid is formed as the deamination proceeds, and is neutralized to maintain the pH above 1:5, or it is removed by an anion exchanger.  The inosine may be separated by crystallization, or precipitated with a metal salt, e.g. a silver salt from which it is recovered by reaction with a sulphide.  In examples ethyl nitrite is reacted with aqueous suspension of adenosine.

Title: Improvements in and relating to the production of semi-crystalline glass articles
IPC: C03C10/00
Filed: 1965-01-13
Abstract: A semi-crystalline glass consists essentially, in per cent by weight, of:  SiO2, 52-70; B2O3, 1-6; Al2O3, 15-30; MgO, 2-7; Li2O, 2.75-6.25; and crystallization promoters, being:  ZrO2, 2-4; SnO2, 0.5-3.  The composition consists of fine crystals of the Li2O/Al2O3/SiO2 system formed in a glassy matrix.  The batch is melted at 2700-2950 DEG  F., and the glass is worked or formed at 2000-2600 DEG  F.  The articles are then cooled to below the nucleating temperature, and are then reheated to 1600-1800 DEG  F. until sufficient crystallization occurs.  The reheating may follow immediately upon the cooling, or after an interval, e.g. for annealing and decorating. The articles are usually translucent and may be white, or coloured by impurities. The non-crystallized glass and the semi-crystalline glass may have coefficients of expansion of 13.7 x 10-7 and 30 x 10-7/ DEG  C. respectively.  The crystals formed are probably b -spodumene, Li2O.Al2O3.4SiO2.

Abstract: 100,854. Lee, G. E. Feb. 2, 1916. Metal pots.-Relates to means for replenishing the supply of molten material to vessels such as the melting-pots of type-line-casting machines. An ingot of type metal is contained in a melting-cup 20, Fig. 3, the lower portion of which is of conical form and has an outlet 22 from which the melted metal passes down a shoot 23 to the melting-pot 1, Fig. 1. The cup 20 is mounted in a housing 5 carried by a platform 4 which is pivoted on a vertical post 3 secured to the machine frame by a bracket 2. Within the housing is supported a circular burner 6 having a gas-supply pipe 7. Pipes 9, 8 communicate with a pilot burner and with a burner for heating the shoot 23 respectively. A casing mounted on a post 12 carries nipples which supply gas to the pipes 7, 8, 9, the supply to the pipe 7 being controlled by a suitable regulating-device operated by the level of the metal in the pot 1. The inner wall of the burner is inclined and has openings through which the gas passes. A series of inclined perforated tubes 18 extend from the top of the burner parallel with the inclined sides of the cup 20. A protecting- casing 24 is supported upon the housing 5. A ring 27 of smaller diameter than the cup 20 holds the ingot in a central position. Guiding-members 28 extend from the ring 27 to a ring 29 and are secured to a circular member 30 carried by the casing 24. The shoot 23 is pivoted and carries a rounded member 31, which serves to raise the shoot as the device is swung away from the melting-pot.

Title: Improvements in or relating to Hose and Half Hose, the Method of and Circular Knitting Machines for Producing the same.
Inventor: STIBBE GODFREY
IPC: D04B9/46
Filed: 1916-02-05
Abstract: 103,190. Stibbe, G. Feb. 5, 1916. Circular machines; knitting stockings and socks. - Comprises a seamless hose or half-hose with a leg a and instep b of patterned fabric, composed of horizontal or horizontal and vertical stripes g, f, and a plain foot bottom e, heel c, and toe d, or with a leg and instep with vertical and horizontal stripes combined with an horizontally striped sole. Vertical striping is effected by employing two threads 11, 12, Fig. 6, of which the thread 11 is missed by the striping-needles 1, which are formed with tail-butts adapted to be depressed by a movable cam 9. Non-striping instep needles 2 are single-butted, whilst the non- striping sole needles are furnished with tail-butts shorter than those of the striping-needles 1. When knitting the leg, the cam 9 engages the butts of the needles 1 only; but, during sole-knitting, it is pushed right in so as to engage all the tail-butts, thus depressing the whole of the sole needles and forming a plain sole. A splicing-thread may be fed in to compensate for the omission of the thread 11. In a modification, single-butted sole and instep needles are employed in conjunction with double-butted striping-needles having long and. short butts on the instep sides respectively; the cam 9 is pushed right in for all-round striping, and is partly withdrawn for producing the piain sole. In this arrangement, the horizontal striping is continued across the sole; but a plain sole may be produced by actuating the horizontal striping-means to withdraw the thread from the sole needles. The horizontal-striping means comprises thread fingers 13, Fig. 5, controlled by a pattern chain 19 through levers 16, 17, such fingers supplying the thread 11. The articles may be furnished with an ordinary rib-top. Specifications 10368/15 and 17175/15 are referred to.

Filed: 1927-01-24
Abstract: 288,747. General Electric Co., Ltd., and Campbell, N. R. Jan. 24, 1927. Light radiations, signalling by. - Light is detected by means. of the change in the normally unstable part U1, U2, of the voltage-current characteristic of a gas-filled photoelectric cell due to a variation in the illumination falling on the cell. The part U1, U2 lies between the ordinary characteristic T1, T2 and the glow - discharge characteristic G, and is stabilized by means of a current-limiting device, such as a thermionic valve, connected in series with the cell, a source of potential greater than that at which the glow-discharge takes place being connected across the cell and valve. The curves TI, S1, U1, and T2, S2, U2 correspond to two different intensities of illumination. A voltmeter taking no appreciable current, for example an electrostatic or a thermionic valve voltmeter, is connected across the cell or the valve and the cell, and on change of illumination the cell passes from curve U1 to curve U2 or from curve U1 two curve T2. Alternatively the point S1 or S2 corresponding to the illumination is found by a sudden change in the reading of the voltmeter.

The invention also includes a process for the preparation of a 3-hydroxy-N-alkylmorphinane wherein the N-alkyl group contains at the most 4 carbon atoms by preparing a 1-p-alkoxybenzyl - 10 - hydroxy - decahydroisoquinoline by the above method, reacting this product with the required N-alkylating reagent to form 1-p-alkoxybenzyl - N - alkyl - 10 - hydroxy - decahydroisoquinoline which is then heated with an aqueous solution of a strong mineral acid, e.g. hydrobromic acid, to form the desired 3-hydroxy - N - alkylmorphinane.  The N-alkylating reagent may be formaldehyde either with hydrogen in the presence of a hydrogenation catalyst, or in the presence of formic acid.  It is preferable to use the sodium bisulphite addition product of p-methoxyphenylacetaldehyde or methyl - 3 - (p - methoxyphenyl) - 2,3-epoxypropionate in the above process.
