Title: An improved process for bleaching artificial fatty acids
IPC: C07C51/487
Filed: 1927-09-07
Abstract: 299,149. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 7, 1927. Fatty acids.-The dark-coloured fatty acids produced by the oxidation of paraffins are purified and bleached by treatment with oxidizing agents such as chromic acid, potassium permanganate and hydrogen peroxide. Chromic acid may be employed in a medium acidified with another mineral acid or with an organic acid other than the acid to be treated. The temperature is preferably above 100‹ C., and may be raised towards the end of the treatment, for instance to 120‹ C. by concentrating the bleaching solution or by working under pressure. The treatment may be effected in stages, the bleaching solution first used being drawn off and replaced by fresh soLution. The process can be carried out in an electrolytic cell containing oxygen transferrers, such as a solution of chromic or ferric sulphate. The fatty acid to be treated may be dissolved in a suitable solvent or may be treated with suitable solvents or absorbents before or after the bleaching treatment. Examples describe the treatment of the crude fatty acids with chromic acid and potassium permanganate in sulphuric acid of 42 per cent.

Title: Improvements in or relating to display arrangements
Inventor: CAMPBELL THOMAS
IPC: G09G5/22
Filed: 1965-06-04
Abstract: 1,145,835. Cathode-ray tube displays. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 1 June, 1966 [4 June, 1965], No.24034/65. Heading H4T. Alpha-Numeric characters are displayed on the screen of a cathode-ray tube by selectively brightening a line scanned raster. The characters are derived in code form (e.g. 6-bit words) successively, from a store DBS (Fig. 1) and each is converted into seven sets of five bits in a translator CT which also produces an additional bit at the end of each set of five to provide character spacing. Each set of bits sequentially operates a respective toggle (to set or reset) in a serializer SE which thus produces seven outputs simultaneously representative of the " brightup " requirement at corresponding positions of seven successive raster lines (each character being displayed in a 7 x 5 matrix). Because of the successive line scanning the " bright-up " control pulses are required sequentially and to produce these the seven outputs from SE are supplied to a video store VS comprising seven delay devices DLM1-DLM7 (Fig. 4) each producing a delay of 6H microseconds (one line scan period) and each having a respective one of the seven outputs applied to input terminals DA1-DA7. The delay devices are connected in series and when a character is to be displayed a " write " signal is supplied to gate circuits G7, G6-via inputs WR7, WR6-resulting in the sequential output at terminal OP1 of pulses appropriate to the " bright-up " requirements of each line in succession. Each row (line) of characters is separated by the space of seven raster lines thus allowing two cathode-ray tubes CRT1, CRT2 to be employed alternately for the display of different data by the use of mixers M1, M2 supplied with the signals from terminal OP1, mixed synchronizing signals MS, and data select signals DS1, DS2. In an alternative arrangement the delay devices have parallel outputs and all (except the first) are provided with regenerative feed-back paths which recirculate the input data until selectively opened by the removal of " read " signals simultaneously with the application of select signals which selectively connect the outputs to a common output terminal (Fig. 5, not shown). In both arrangements the time for which the store DBS, code translator CT and serializer SE are idle (i.e. for six line periods in every seven line periods) may be utilized to control six additional video stores VS each supplying two cathode-ray tubes. The delay elements in each delay device comprise an ultrasonic delay line UDL1 of 63À12 Ásec. delay and a lumped constant delay line LDL1 of maximum delay 0À2 Ásec. adjustable in steps of 0.01 Ásec. the remainder of the 64 Ásec. delay being made up by the delays in amplified inverters INV1- INV4.
