Abstract: 1,208,336. Purifying water by flocculation. W. SQUINDO. 27 June, 1968 [27 June, 1967; 8 Dec., 1967], No. 30676/68. Heading C1C. Water is purified by flocculation by addition of water-soluble zinc salts and adjustment of the pH of the water to a value between 7À8 and 8À5 by addition of an alkali-metal salt of boric acid, before, during or after the addition of the zinc salt. The pH can be adjusted to the range 7À4-7À8 by a strong alkali, e.g. caustic soda or potash, and the remaining pH correction of at' least 0.4 units is carried out by means of the alkali metal salt of boric acid. After flocculation the water may be filtered through a layer of activated charcoal. The types of water treated are fresh waters from lakes and rivers, effluents from biological purification of waste household waters, sewage liquors, industrial and household waste waters and active muds of secondary settling tanks and biological purification plants.

Title: Improvements in and relating to joints for electric cables
IPC: H02G15/25
Filed: 1935-11-06
Abstract: 445,333. Cable joints. BRITISH. THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. Nov. 6, 1935, No. 30712. Convention date, Nov. 6, 1934. [Class 38 (i)] Relates to a stop joint for a cable which is enclosed in a pipe filled with insulating fluid under high pressure. According to the invention, the joint comprises a casing 9 having a partition 10 fitted with porcelain insulators 14, 15, which are subjected to compression by the insulating fluid, and means are provided for applying pressure to the spaces within the insulators in order to reduce the effective pressure to which the insulators are subjected. The insulators 14, 15 are fitted over an opening formed in the partition 10, and a connector 19 is clamped in the outer end of each insulator by means of nuts 26. Each connector has a cylindrical portion 22<a> which extends towards the partition 10 and slides into a tube 24, flexible connectors 25 being soldered both to the connectors 19 and to the tube 24. The arrangement of the tube and the connectors permits proper seating of the connectors without subjecting the insulators to strain, and allows for any misalignment or variations in length of the insulators. The tube 24 is surrounded by a wrapping of insulation 30 the ends of which are supported by thin metal shields 31 surrounding the connectors. A space 32 surrounds the wrapping, and oil or gas under pressure is applied to these spaces by means of supply pipes 33 and channels 34 formed in the partition 10. The pressure of the fluid on the inner walls of the insulators partly compensates for the high pressure exerted on the exteriors of the insulators. Shields 31, 36, 37, 39 control the distribution of electric stresses.

Title: Apparatus for qualitatively assessing characters recorded on a document
IPC: G06V10/98
Filed: 1971-07-01
Abstract: 1357423 Character recognition systems INTERNATIONAL COMPUTERS Ltd 3 July 1972 [1 July 1971] 30849/71 Heading G4R To determine whether a character on a document is suitable for machine reading, signals representing elementary areas of the character field are correlated with a representation of the corresponding ideal character. The signals are shifted relative to the representation to develop a series of correlation values, and the degree of mismatch indicated by the values is shown on a meter. If the mismatch reaches a sufficiently small value the character is suitable. The document is mounted on a carriage positioned with a desired character beneath a scanner by means of coarse and fine manually operated mechanisms. The character is projected on to a line of photo-cells by a lens. To scan the character over the cells the lens is reciprocated in its plane. The photo-cell outputs are sampled by clock pulses whose repetition rate varies sinuosoidally in synchronism with the movement of the lens. The photo-cells feed threshold units connected to bi-stables, the outputs of the bistables passing to respective shift registers under control of the clock pulses. The parallel outputs of the registers are fed to a resistor matrix representing black and white masks for all the possible characters. A manually operated switch selects the outputs of the two masks corresponding to the scanned character, and the difference of these outputs, representing the varying degree of mismatch as the character signals shift through the registers, controls a meter.
