Title: Effluent purificn. in paper esp kraft pulp prodn - by passage through crosslinked aliphatic esp acrylic anion exchange resin
IPC: C02F1/28
Filed: 1975-10-22
Abstract: A process for purifying, including decolourising, an effluent stream from paper mfr. comprises passing the effluent, the pH of which has been adjusted to 6-8.5, through a bed of cross-inked aliphatic weak anion exchange resin, the resin being in the form of a weak base, so as to remove coloured substances and impurities by retention on the resin. Partic. for decolourising and removing lignin materials from effluents formed in non-bleached kraft pulp prodn. Pptn. of coloured substances in the resin column is avoided. The process also allows a reduction in the biological and chemical oxygen demands and obviates the need for handling sludges and formation of excessive amts. of Na2SO4 cakes.

Title: Diaphragm clutch disengagement springs and thrust coupling - has washer connected to diaphragm via projecting tongues in radial slots
IPC: F16D13/71
Filed: 1975-12-05
Abstract: At least three retraction springs (11) are mounted equally spaced, externally, between the outer edge of the cover (7) and the rim of the pressure plate (5), passing through windows in the cover. These springs instantly cause disengagement on declutching, since they act in opposition to the diaphragm force. The washer (12) of the thrust bearing is connected to the diaphragm via projecting tongues (12a) which are curved inwards and located in radial slots (8a) in the diaphragm. The tongues are retained on the other side of the diaphragm by an expansion ring (14). All play between thrust washer and diaphragm is taken up by an elastic mounting. The clutch plate is driven directly by the cover, which is rigidly fixed to the flywheel.

Title: Pitch prilling plant - which passes hot fluid through perforations to solidify free falling droplets in cooling bath
IPC: C10C3/16
Filed: 1976-02-05
Abstract: Liq. hydrocarbons such as electrode pitch are converted into prills by breaking up jets into spherical droplets of specified dia. The droplets fall through a gas space into a cooling bath of a non-miscible fluid. The bath temp. is low enough to solidify the droplets without letting them stick together or breaking them up. The prills have a uniform size and cause no dust or stickiness problems in handling. The plant takes up less space than conventional pelletising equipment and requires less maintenance.
