Title: Process for preparing polyphenoxylene
IPC: C08G65/38
Filed: 1964-09-08
Abstract: Solid linear polyphenoxylene polymers are obtained by heating a suspension of an alkali metal salt of a monohydric halogen-substituted phenol in an inert non-polar aliphatic hydrocarbon liquid under anhydrous conditions in the presence of an elemental copper catalyst at 150 DEG  C. to 250 DEG  C.  The salt may be formed in a solvent of lower boiling point than the hydrocarbon liquid, the salt and solvent dispersed in the hydrocarbon liquid, and solvent and water removed by distillation. High-boiling solvents or surface-active compounds may be added to the polymerization mixtures as dispersants.  In examples polymers are obtained from sodium and potassium o-, m- and p-chloro- and bromophenoxides in eicosane, liquid petrolatum and phenyl ether in the presence of powdered copper; phenyl ether, phenylcyclohexane and fluorocarbon surface active agents are used as dispersants.

Abstract: 1517797 Deflection circuits for television; correcting distorted raster R C A CORPORATION 9 Sept 1975 [27 Sept 1974] 37061/75 Headings H3T and H4T [Also in Division G4] In a deflection waveform correction system for television apparatus, a sawtooth waveform 404 is generated, varying as a function of the square root of the accelerating anode voltage HV and is applied to a circuit 230 having a cubic function, arranged to provide a S-correction component 506 which is combined at 241 so as to provide an S- wave 410 which does not contain a cubic component of the square root of voltage HV. The specification describes a field deflection circuit and explains by means of Taylor's series that the square root of HV is approximately proportional to the sum of a voltage proportional to HV with a fixed voltage B+. Capacitor 209 is charged with this function and periodically discharged by field frequency pulses 402 derived from a countdown circuit 201 supplied with twice line frequency pulses 2f H . The resultant is phase compared with the field pulses f V . The field frequency sawtooth 404 is amplified at 217 and fed to a correction circuit 230 having a cubic law to provide S- correction. Circuit 230 includes a pair of multipliers M1, M2, Fig. 2, which ensure that the S- correcting waveform 506 contains no cubic component of the square root of HV. After combining or subtracting in circuit 241 and further amplification at 243, 245 ... 249, the deflection waveform is fed to the field deflection coil 251, negative feedback being provided across resistor 252.

Abstract: 786,025. Digital electric calculating and data-storage apparatus; statistical apparatus. DIRKS, G. June 23, 1950 [Oct. 1, 1948], No. 37204/54. Divided out of 786,021. Class 106 (1). Means for transferring signals from a first to a second record means but in a different sequence, comprises means for sensing the first record means in successive stages of a first sequence, distributing means for transmitting signals to the second record means at determined time instants in a cycle of operation and selective switching means determining at what times in the cycle the sensed signals are to be transmitted. In the described embodiment a perforated record card 22 is fed under a row of sensing brushes 7<SP>1-n</SP> in synchronism with the rotation of a shaft 31 carrying a commutator C. Gearing 30, 29 causes a second shaft 27 to be rotated at twelve times the speed of shaft 31, so that a magnetic drum store 26 makes one complete rotation during the sensing of each row on the card 22. The sensing brushes 7<SP>1</SP>-<SP>n</SP>, shown diagrammatically in Fig. 2, are connected to the vertical columns 3<SP>1-n</SP> of a plugboard 1, the horizontal rows 2<SP>1-n</SP> being connected to windings 4<SP>1-n</SP>, each on one arm of a U-shaped transformer core (see also 41, 5<SP>1</SP>, Fig. 4); the windings on the other arms 5<SP>1-n</SP> are connected in series to output terminals 19, 20. A projection or tooth 10 on a wheel fixed to the shaft 27 traverses the whole series of windings 4<SP>1-n</SP>, 5<SP>1-n</SP> once during the sensing of each row on the record card, and as it momentarily increases the inductive linkage between associated windings, any winding 4<SP>n</SP> which has become energized by direct current from terminal 6, via plug connection 18<SP>n</SP>, sensing brush 7<SP>n</SP>, card perforation p, common conductor 8 and terminal 17, gives rise to an impulse in the corresponding winding 5<SP>n</SP>. This is applied via terminals 19, 20 to a circuit controlling the writing heads H of the magnetic drum store. In this way the sequence of the digits recorded in the columns of the card 22 is changed in accordance with the positioning of plug connections 18<SP>1-n</SP> and the digits are entered into the magnetic store in the new sequence. In the embodiment described the digits are added to amounts which may be already recorded in the store by computing means described in Specification 786,021. Instead of a single row of brushes sensing the rows in succession, brushes may be provided for sensing all index positions simultaneously (Fig. 5, not shown), and rows may be examined in succession by inductive scanning means similar to that described above. Other forms of storage may be used including cathode-ray tube storage means.

An electrically operated vehicle comprises an electric driving motor C and a battery 2 together with a pair of generators A, B driven by a single internal combustion engine, the field winding 6 of the generator B being connected between a centre tap on the battery 2 and a slider 7 of a potentiometer 8 connected across the battery and the armatures of the generator B and the motor C being connected in a series circuit with the battery 2 so that movement of the slider 7 from end to end of the potentiometer 8 causes a variation in the generated voltage of the generator B to give full buck to full boost of the battery voltage thereby controlling the motor C from standstill to full speed. Regenerative braking of the motor C is obtained by moving the slider 7 so that the voltage applied to the motor is less than the back E.M.F.

Abstract: 1,160,716. Electrotype printing plates. UNION CARBIDE CORP. 26 Aug., 1966 [27 Aug., 1965], No. 38472/66. Heading B6C. Electrotype printing plates are produced by rendering the surface of a thermoplastic polyarylene polyether matrix electrically conductive, forming a shell of platable metal 0À5 to 7À0 mils thick with a roughened, semi-porous back by electrodeposition, and then, while still maintaining the shell in contact with the matrix, backing the shell with a thermoplastics material by means of heat and pressure. The polyarylene polyether matrix is made electrically conductive by either applying a conductive silvering solution or by electroless deposition of a thin metal layer on the surface. The electroplating for the formation of the electrotype shell, preferably of nickel or copper, is carried out in an agitated bath which contains 0À1 to 20% by weight of a fine powder of the same metal as the one being electrodeposited, the roughened back of the shell being a consequence of the presence of the powder. The shell is backed with a thermoplastics material, e.g. polyvinyl chloride or a polyhydroxy ether resin, at pressures between 60 and 1500 p.s.i.g. and temperatures between 93‹ C. and 177‹ C. The resulting electrotype printing plate may remain in contact with the matrix during finishing operations, or may be separated and faced with a thin layer of chromium.
