Title: Preparation of stable solutions of segmented linear urea/urethane polymers
IPC: C08G18/48
Filed: 1965-06-29
Abstract: Stable solutions of segmented linear urea/urethane polymers are prepared by adding to the solution of the polymer in a solvent when the viscosity of the solution reaches a value corresponding to an inherent viscosity of the segmented polymer of at least 2.0 but before the viscosity becomes too high for spinning or casting a viscosity stabilizer which is a halide or the anhydride of a monocarboxylic acid having from 2 to 15 carbon atoms in a proportion of 0.01 to 5% by weight based on the weight of the segmented linear polymer in the solution.  The solutions of segmented linear polymers which may suitably be stabilized are those which have been prepared by the processes described in Specifications 1,118,731, 1,118,732, 1,118,733, 1,118,734 and 1,118,736. Suitable stabilizers are acetic anhydride, acetyl chloride, benzoyl chloride and benzoyl fluoride. Examples describe the stabilization of a polymer derived from p-xylylene diisocyanate, copoly (tetrahydrofuran + 6 mole per cent trans - 8 - oxabicyclo [4.3.0] nonane) and 2,2,4,4-tetramethyl - 1,3 - cyclobutanediamine with acetic anhydride, acetyl chloride and benzoyl chloride. The stabilized solutions may be spun into filaments or cast into films.

Abstract: 1,270,437. Thermocouples. ROLLS-ROYCE Ltd. 20 July, 1970 [30 May, 1969], No. 27527/69. Heading H1K. A tungsten or tungsten-alloy/rhenium thermocouple junction is embedded in a silicon-nitride body. A graphite die is partially filled with powdered Si 3 N 4  mixed with a flux which may be MgO, the powder is lightly compressed, a thermocouple is positioned and the die filled with powder, closed, and heated in a non- oxidizing atmosphere. The non-oxidizing atmosphere may comprise a vacuum, an inert gas, nitrogen, or the powder may be damped with alcohol which evaporates slowly to displace the air until the temperature of the graphite die is high enough for it to absorb the oxygen. The W may be alloyed with Re, Mo, Hf or Zr and may be thoriated. W inserts may be moulded-in and exposed by machining back the Si 3 N 4  so that the inserts can be drilled and threaded to allow the device to be mounted on a support.

Input liquid is supplied to the ports S and is equally divided between ports A and B. For simplicity operation is described with reference to Fig. 2. Source liquid S is supplied to both ports 1 and in cylinder 1 flows through a chamber 30, out of a port 4 and into chamber 21 in cylinder 2 to push the piston to the right. This displaces liquid from a chamber 22 of cylinder 2 with a chamber 33 of cylinder 1 through a port 5. From here it goes out through a port 2 into line B. As the piston in cylinder 2 moves to the right ports 4 and 3 are connected and ports 5 and 1. Liquid from port 1 of cylinder 2 now flows through port 5 to chamber 31 of cylinder 1 so that the piston in cylinder 1 begins to move to the right. This displaces liquid from a chamber 32 through port 4, chamber 24 of cylinder 2 and port 3 to the line A. This movement of the pistons continues, one leading the other and liquid is alternately fed to lines A and B. In a similar manner inputs to lines A and B may be combined in equal volumes and fed out at lines S.

Abstract: 417,970. Stays ; easel stands. CARWARDINE, G., 17, Macaulay Buildings, Bath. Oct. 7, 1933, No. 27634. [Class 65 (i).] A device for ensuring the stability, at any inclination, of a strutted mirror, picture, stand or the like, comprises a tension spring connected betweer the back of the mirror or the like and a lever pivotally connected to the latter in pressure co-operation with the strut, the arrangement being such that the lever does not rotate in a vertical plane as the mirror or the like is tilted ; the spring is preferably such that its tension is proportional to its length. The device is shown applied to a mirror having fixed to its back a bracket a with a pivoted strut b, both strut and bracket carrying rollers for resting on a table. A lever f, pivoted to the bracket a above the point of attachment of the strut b, is pressed by a tension spring i, connected to the bracket a and the lever, against a pin or roller h carried by the strut b. The length of the strut b is made equal to the length of the bracket a below the pivot of the strut, and the pin h is placed at a distance from the pivot of the strut equal to the distance between the latter pivot and the pivot of the lever f. The abutment surface of the lever is substantially straight and parallel to the line of centres of the pin h and the pivot of the lever, and has stop surfaces at its ends to limit the settings of the strut. Owing to the proportions of the device, the lever f remains vertical in any setting of the mirror ; by modifying the positions of the lever pivot and the pin h, without altering the proportions of the parts, it can be arranged in a horizontal or any other position.

A circuit for comparing two binary numbers employs a majority logic circuit for each digit comparison stage. A similar circuit can be arranged to provide a carry-indication output in an addition operation. As described,for comparing two four-digit binary numbers in registers 30, 32 with the highest order at the left,a comparison circuit comprises four 3-input majority logic circuits 34, 36, 38, 40 each comprising a tunnel diode (Fig. 1, not shown) and adapted to provide a "1" output when a "1" is applied to any two or all three of the three inputs. One input of each logic circuit is connected to the normal output of the corresponding stage of the register 30, the second input being the complementary output at the corresponding stage of the register 32 and the third input being from a backward diode such as 42 connected to the output of the majority logic circuit of next lower order, except for the lowest order which is permanently connected to a "1" input. A "O" output at 52 is obtained if the number in the register 30 is less than the number in the register 32, a "1" output at 52 being obtained in other cases. A second comparison circuit 44-50 is provided, having an output at 54, the two outputs 52, 54 enabling equality of the two numbers compared to be distinguished. By connecting each logic circuit to the normal output of both corresponding register stages, a carry output for the addition of the two numbers can be obtained at 52.

Title: Process for the purification of dialkyl esters of terephthalic acid
IPC: C07C69/82
Filed: 1955-09-30
Abstract: Dialkyl terephthalates are purified by heating the dialkyl ester for at least five hours at temperatures of at least 200 DEG  C. and separating the treated esters and the impurities present therein in known manner.  The starting material is preferably purified before the heating or alternatively the heat treatment may be repeated.  The separation of the ester after heating may be by distillation or crystallization.  The heating may be carried out at increased, normal or reduced pressure and preferably in the presence of oxygen, or an inert gas such as nitrogen or carbon dioxide.  Metals and metal oxides inert towards the esters may be used as catalysts.  Specified metals whose oxides may also be used are silver, aluminium, iron, copper, zinc, manganese and lead. In examples: (1) dimethyl terephthalate, purified by crystallization or distillation, was heated or refluxed at normal pressure, distilled in vacuum and the product compared for heat stability with untreated material; (2) crude dimethyl terephthalate was treated as in (1), the distillation being in vacuum or under normal pressure and the product being further purified by distillation in vacuum; (3) crude dimethyl terephthalate treated as in (1) but in the presence of copper, zinc, iron, aluminium, manganese dioxide, red lead or silver; (4) crude dimethyl terephthalate was treated as in (1) but air was continuously passed during refluxing; (5) crude dimethyl terephthalate was heated in a closed flask and distilled at normal pressure; (6) dimethyl terephthalate was heated in a shaking autoclave under pressure of nitrogen and distilled in vacuum.
