Title: Graft copolymer compositions and process for their production
Inventor: LANE ZIMMERMANN ROBERT
IPC: C08F10/00
Filed: 1959-09-02
Abstract: Graft polymers are produced by polymerizing one or more alkenyl aromatic monomers of the formula: CH2=CGAr wherein G is hydrogen or methyl and Ar is a C6-C10 aromatic radical, if desired in admixture with up to 100 mole per cent of one or more acrylic monomers of the formula <FORM:0917499/IV(a)/1> wherein R may be hydrogen or methyl and Q may be a nitrile, amido, carboxyl or methyl or ethyl carboxyester group, in the presence of an elastomeric copolymer of ethylene and one or more vinyl ether and/or vinyl ester monomers. The polymerization is preferably carried out by dissolving the ethylene copolymer in the monomer, the reaction being accelerated by means of heat, peroxide catalysts or high energy irradiation.  The examples describe: (1) polymerizing styrene with a copolymer of ethylene and the divinyl ether of diethylene glycol by heating; (2) as in (1) but employing vinyl toluene as the alkenyl aromatic monomer; (3) polymerizing styrene with a terpolymer of ethylene and the mono- and di-vinyl ethers of ethylene glycol by heating; (4) polymerizing styrene or vinyl toluene with a copolymer of ethylene and the monovinyl ether of diethylene glycol; (5) polymerizing vinyl toluene with a copolymer of ethylene and vinyl acetate; (6) polymerizing styrene with a terpolymer of ethylene, vinyl acetate and diethylene glycol divinyl ether in the presence of tert. butyl hydroperoxide; and (7) vinyl toluene is polymerized in the presence of a terpolymer as in (6).

Title: Improvements in or relating to electrical measuring bridges
IPC: G01R17/00
Filed: 1956-08-31
Abstract: 816,242. Measuring bridges. WAYNE KERR LABORATORIES Ltd., and CALVERT, R. Aug. 19, 1957 [Aug. 31, 1956], No. 26713/56. Class 37. Input transformer 10 of an A.C. energized impedance bridge has series secondary windings 14, 15 forming ratio arms whose junction is connected over a neutral line to one end of primary 17 of transformer 18 energizing detector 20; the free ends of windings 14, 17 being interconnected by unknown inductive impedance 19, while winding 15 is shunted by variable potentiometer 22 energizing a standard reactance T-network comprising series input and output resistances 24, 25 shunted to neutral over capacitance 28 and connected between potentiometer tap 23 and a variable tap 26 on further primary 27 of the detector transformer 18. By adjustment of tap 23, the detector transformer ampere turns derived from the T-network are balanceable against those from the inductive component current in the unknown 19, and it is shown that for zero detector output, where L is the inductance, E u  the voltage applied to the unknown, Es the voltage applied to the T-network, C the capacitance (of small impedance compared to the resistances), R 1  and R 2  the first and second resistances, and N is the turns ratio of the detector transformer windings associated with the third and fourth bridge arms. Capacitance 28 may be adjustable in value and the inductance of the unknown 19 is measurable by reference to the setting of potentiometer 22 for balance. The resistive component of the impedance 19 is measurable by reference to the setting of a variable impedance 30 connected between a tap on detector transformer winding 17 and the free end of winding 15; the variable in-phase current component through which is balanceable against the in-phase current component through impedance 19. If the latter is of high Q, accurate measurement of its loss resistance necessitates balancing in transformer 18 the in-phase current component through 24, 25 by a potentiometer 31 shunted across the input to the T-network whose variable tap is connected through resistance 33 to a further adjustable tap on detector transformer winding 17. The loss resistance is thereafter measured by adjustment of standard resistive impedance 30 for further balance.

Title: Process for the separation of argon from mixture with oxygen and nitrogen
Inventor: ARMOND JOHN WALTER
IPC: C01B23/00
Filed: 1960-08-02
Abstract: <PICT:0927072/III/1> Argon is separated from oxygen and/or nitrogen by passing the gas through an adsorption zone countercurrent to a downwardly moving bed of granular adsorbent material at a temperature of -90 DEG C. or below but above the liquefaction temperature of the feed gas whereby oxygen and/or nitrogen are preferentially adsorbed, and subsequently subjecting the adsorbent bed to a gradually increasing temperature in a rectification zone below and continuous with the adsorption zone, whereby the adsorbed gases are desorbed and removed.  Argon is withdrawn from the top of the adsorption zone.  In one embodiment a liquid feed is used which evaporates on contact with the adsorbent.  As exemplified and shown in the Figure, argon containing 2% oxygen and/or 0,3% nitrogen is fed into column 1 by inlet 2 at the foot of adsorption zone 3, which is cooled by liquid oxygen coils 4 to -183 DEG C. Adsorbent descends through rectification zone 5 heated at its base by heater 6 so that gas is desorbed and withdrawn through outlet 7.  Screw conveyer 9 removes the adsorbent, which is recycled by gas lift through pipe 10. Purified argon is withdrawn through pipe 8, and some of this is recirculated through pipe 11 and blower 12 to operate the said lift, the pressure being adjusted so that a portion flows through screw 9 and up the column, thereby functioning as a purge gas and preventing contamination of the product.  Specifications 777,232 and 777,233 are referred to.

Filed: 1926-10-27
Abstract: 280,351. Marks, E. C. R., (Poulsen & Co., L.). Oct. 27, 1926. Overhead lamps.-In an overhead lamp for producing diffused light, an electric lamp bulb 2 is surrounded by a number of downwardly directed shades 3 - - 5, the under surfaces of which are dull and of such curvatures that all rays of light from the bulb which strike the shades do so at angles greater than 45‹ to the normals at the points of incidence. For this purpose the central portion of shade 3 is bent inwards slightly towards the bulb 2. The diffusion effect may be regulated by varying the degree of dullness of parts or the whole of the shades. The backs of the shades 4, 5 may be mirrored so as to reflect any light reflected downwardly on to them by the shades 3, 4. Also, use may be made of an undershade 6 having a bright inner surface, so as to screen the bulb 2 and to reject light on to the dull shades.
