Title: Acrylonitrile Copolymers Containing Sulphonylaminooxalyl Groups
Inventor: RINKLER HEINRICH
IPC: C08F220/46
Filed: 1967-07-31
Abstract: 1,186,107. Dyeable acrylonitrile copolymers. FARBENFABRIKEN BAYER A.G. 31 July, 1967 [29 Aug., 1966], No. 35083/67. Heading C3P. Acrylonitrile copolymers having a high affinity for basic dyes are prepared by copolymerizing a monomer mixture comprising at least 50% by weight of acrylonitrile and 0À1-20% by weight of an ethylenically unsaturated sulphonylamino-oxalyl compound (containing the characteristic group -SO 2 -NH-CO-CO- or an alkali metal salt form thereof), the balance of the mixture, if any, being one or more additional copolymerizable monomers. The sulphonylamino-oxalyl monomers exemplified are derivatives of (meth)acrylamide and methacrylate esters and of vinyl sulphonamide and, generally, are aromatic compounds. Optional comonomers mentioned are acrylates and methacrylates, vinyl esters, styrene and its neutral derivatives, vinyl and vinylidene halides, butadiene, chloroprene, acrylamide, methacrylamide, vinyl alkyl ketones, vinylidene cyanide, divinyl compounds, and basic monomers such as vinyl pyridine. Polymerization may be effected in aqueous emulsion, dispersion or solution using azo, peroxy or redox initiators. Regulators, e.g. mercaptans, or complexing agents may also be present, and polymerization may be effected continuously or batchwise and may be terminated at desired conversion by addition of an inhibitor. The copolymers can be formed into fibres or films, which are readily dyed with basic dyes.

Title: Cathode Ray Tube Digital Display System
Inventor: TROUSDALE ROBERT BASHFORD
IPC: G09G1/10
Filed: 1967-08-03
Abstract: 1,197,793. Cathode-ray tube displays. CALIFORNIA COMPUTER PRODUCTS Inc. 3 Aug., 1967 [3 Aug., 1966], No. 35787/67. Heading H4T. A graphical display is produced on the screen of a cathode-ray tube by deflecting the beam to selected dot positions under the control of digital signals which determine the X and Y coordinates of the dots. Additionally, the intensity of the trace is controlled by bright-up pulses of constant amplitude and of a duration determined by further digital signals. As shown in Fig. 2, a data processor 21 (e.g. a computer) supplies the digital signals to respective X, Y and Z axis registers 35, 36, 37 and thence to X and Y register ladders 45, 46 operating as digital-to-analogue converters (Fig. 3, not shown) and supplying deflection currents to the deflection coils of the display tube 31 and to an intensity control device 48 which supplies the variable duration bright-up pulses to the beam intensity control electrode. Device 48 includes a threshold circuit and a number of resistors and capacitors which are selected in RC pairs in accordance with the digital signals from the Z-axis register to provide time constants of appropriate value for controlling the duration of the bright-up pulses (Figs. 4 and 7, not shown). The invention is stated to be suitable for displaying continuous trace display such as the graphs 12 and 14 or discontinous trace display such as the numeral 3, 13 (Fig. 1a). The form of the displays is shown in Fig. 1b in which, for beam deflections in the X or the Y co-ordinate directions a constant duration bright-up pulse is applied to the tube for each dot position resulting in overlapping bright dots. When the deflection is inclined to the X and Y areas, however, the duration of the bright-up pulses is varied and as shown in Fig. 6, due to blooming effects on the tube face an apparent variation in the dot diameter results. An apparent variation in dot diameter with duration of the bright-up pulses is also produced in the photographic emulsion when the display is recorded photographically by means 51, 52, 53. The control of the whole system by the mode control device 38 is described by means of logic equations in conjunct - ion with a Veitch diagram (Fig. 8, not shown).
