Title: Devices for effecting particle growth in flowing liquids
IPC: C02F1/52
Filed: 1975-04-03
Abstract: 1501697 Coalescing and settling particles PIELKENROOD - VINITEX BV 3 April 1975 [12 April 1974] 13596/75 Heading BID In an apparatus for effecting the growth of particles in a flowing suspension which is to be separated by settling the apparatus comprising chambers connected in series and chambers connected in parallel, the suspension flows vertically through a plurality of chambers, the flows in successive chambers being in opposite directions, and the suspension is divided into parallel streams during its flow through the apparatus. In use, wall friction in the chambers causes differences in the velocity of the particles in the suspension so that coalescence of the particles occurs. The flow velocity of the suspension at any point in the chambers is such that no separation of the particles takes place in the chambers and is lower than the velocity at which coalesced particles would be disrupted by shearing action as a consequence of the velocity gradients in the vicinity of that point. In the embodiment shown, suspension from trough 5 passes through chambers 13, 14. Suspension from chamber 14 is passed into two chambers 16 (only one shown) connected in parallel and from each chamber 16 the suspension flows into two chambers 17 arranged in parallel. Each chamber 17 supplies suspension to a supply chamber 7 containing a plate separator 2 e.g. as described in Specification 1295123. The chambers may be subdivided by corrugated plates. Tank 1 may be metal or concrete. The walls of the chambers may be detachably mounted in grooves.

Title: Joints
IPC: F16F1/393
Filed: 1944-07-18
Abstract: 593,466. Flexible joints. LORD MANUFACTURING CO. July 18, 1944, No. 13718. Convention date, July 8, 1943. [Class 108 (iii)] In a joint comprising two units each of which has two members having conical opposing surfaces separated by an element of resilient material bonded to the surfaces, means are provided to secure the members of one unit to the members of the companion unit so as to pre-stress the resilient material in one unit in a direction opposing the stress in the resilient material of the companion unit. The joint, Fig. 3, consists of two units shown in the unstressed condition, Fig. 2, mounted on a splined shaft 6. The resilient material 5 is bonded to the inner and outer conical surfaces of the members 1, 3 and is stressed in the axial direction when assembled in the joint by nuts 13 through the ring member 14 and the eye of the torsion arm 10a. Before assembly, the resilient material is also placed under torsional stress by rotating the outer members 3 of the units in opposite directions relatively to the rod 6 and then locking them in position by means of a key 16 fitting into two slots in the members. The key 16 may project above the surface of the members 15 and be used in conjunction with a slot 18 in the supporting member 17 to prevent rotation of the joint with respect to the supporting member. The joint may, in addition, be locked in position by a set screw 19. In a modification, Fig. 8, the two units are held and axially stressed in the supporting arm 36 by plates 37. Set-screws 38 securing the plates 37 to the outer members 24 of the units allow the resilient member to be torsionally stressed to any desired degree. The purpose of the axial stressing is to place the resilient material in compression, the degree of torsional stressing is such that under no conditions of movement of the torsion arm does the stress in the rubber change its direction and thus cause fatigue.

Abstract: 813,420. Centrifugal separators. NASH ENGINEERING CO. April 30, 1957 [July 27, 1956], No. 13719/57. Class 23 [Also in Group XXVI] In the liquid-ring pump shown in Fig. 1, a mixture of compressed gas and liquid entrained from the liquid ring is discharged through discharge ports 50 and passages 59 to auxiliary axial-flow impeller blades 76, which expel it to a separating chamber 78. The blades 76 also have a centrifugal separating action, whereby liquid is thrown outward and gas is forced towards the centre. Separated gas passes through a central opening 83 to a passage 86 leading to a discharge pipe 88. The opening 83 is restricted to provide a high gas velocity for the purpose of muffling the noise made by the pump. The separated liquid is drained off through a pipe 82. The pump may be disposed with its shaft horizontal and the drain pipe 82 directed downwards. Fig. 6 shows a modification in which the auxiliary axial-flow impeller blades 76b have extensions forming centrifugal impeller blades 132 which discharge the separated liquid through a volute 128. Separated gas and vapour is discharged through a central pipe 135.

Patent GB-573111-A (GB)
Title: Improvements in and relating to the treatment of coal tar distillates and the like
IPC: C07C7/10
Filed: 1942-10-19
Abstract: Aromatic hydrocarbons having a non-aromatic double bond such as styrene and indene are separated from light coal tar distillates and like hydrocarbon mixtures containing also saturated aromatic hydrocarbons by adding a solvent containing formic acid, a polyhydric alcohol or its ester or any admixture thereof to form a solution containing an increased ratio of said unsaturated to saturated hydrocarbons and an immiscible residue, rendered immiscible if necessary by addition of a liquid or a salting-out agent.  Suitable solvents are propylene and diethylene glycols, mono-and di-acetin or mixed solvents such as 80 per cent formic acid and 20 per cent acetone.  The hydrocarbons can be recovered from the solvent by adding a further solvent such as water which causes precipitation or by salting-out as by addition of sodium formate to a formic acid extract.  The concentration of unsaturated hydrocarbons, for example styrene, in the solvent phase can be increased by repeated extraction with the same or a different solvent or by extraction with a liquid which is a solvent for the hydrocarbons, but immiscible with the first solvent, preferably a petroleum fraction boiling below styrene, e.g. below 100 DEG  C.  Alternatively, the solvent phase may be extracted with a styrene solution of the concentration desired. The process may be effected using a counter-current extraction with reflux.  In examples: (1) coal tar naphtha boiling at 130-160 DEG  C. is treated in a packed column with propylene glycol in counter-current.  A refined naphtha layer is withdrawn at the top while the solution drawn off at the base is diluted with water causing separation of a hydrocarbon layer containing 15 per cent unsaturateds, mainly styrene; (2) the product of dehydrogenation of ethyl benzene is treated similarly with diethylene glycol, the hydrocarbon layer being removed from the glycol by vacuum distillation and recycled, while the glycol layer is vacuum distilled to recover hydrocarbons containing 50 per cent or more of styrene; (3) aromatic hydrocarbons, 40 per cent styrene, are dissolved in diacetin and passed countercurrent to petroleum ether, B.P. 70 DEG C., yielding a diacetin solution of hydrocarbons which are 80 per cent styrene; (4) a diethylene glycol solution obtained in (2) containing 20 per cent hydrocarbons of which 50 per cent is styrene is treated with a mixture of 80 per cent styrene with 20 per cent saturated aromatic hydrocarbons.  A solution containing 25 per cent hydrocarbons of which 80 per cent is styrene is obtained, in addition to a hydrocarbon layer containing some dissolved glycol and only 5 per cent styrene which may be further treated as in (1) or (2).
