Abstract: 1,252,172. Hydrocyclones; separation of solvent from a solution of a solid organic compound by evaporation. STAMICARBON N.V. 27 Feb., 1969 [28 Feb., 1968], No. 10645/69. Headings BIB and B2P. In a process for removing an organic compound from a solution thereof in an organic solvent of specific gravity lower than water, the solution is contacted with water at a temperature near the boiling point of the solvent under the prevailing pressure, organic solvent is removed by evaporating an inner organic solvent layer from an outer aqueous layer in a vortex flow of the liquids, and the aqueous phase containing particles of the organic compound dispersed therein is recovered. Organic compounds specified include polymers of diolefins, or copolymers of ethylene with at least one other alkene and/or at least one polyunsaturated compound. Solvents used may be hexane, heptane, petrol, kerosene or benzene. The specific gravity of the water phase may be increased by the addition of soluble salts, e.g. ammonium sulphate, or suspended substances. As shown in Fig. 1, hot water is supplied via a tangentially disposed feed pipe 2 to a vortex chamber 1. The solution of organic compound in solvent is introduced into the pipe 2 via a line 3 as a result of which the organic compound is transformed into solid particles. In the vortex chamber, the solvent evaporates from an inner layer 5 through a hollow space 6 and a line 7 and the solid particles are separated out in an outer layer 4 of water and are discharged therewith through an opening 8 into a tank 9 which may be provided with an agitator to keep the particles in suspension. Water and solid particles are removed through a line 10 while water, which may contain some solid particles is recycled through the vortex chamber via a line 11, a pump 12 and a heater 14. The modifications (a) the organic solution is introduced directly into the vortex chamber either radially or through a line parallel to and offset from the chamber axis; (b) the solvent vapour is discharged through an opening in the bottom of the chamber instead of through an upper line as at 7; (c) the vortex chamber has a lower cylindrical portion with an opening in its base for the discharge of solid particles and an upper frusto-conical portion with an opening for the discharge of solvent at its apex, the water feed pipe being fitted near the base of the chamber and the organic solution being introduced as in (a) above.

In a vehicle, a safety belt system comprises a belt 4 consisting of at least two interconnectable straps and a locking device, not re-  sponsive to inertial forces, but actuated in  responce to the depression of the vehicle brake pedal by the driver. The depression of the brake pedal 1 closes a switch 2 and energises a solenoid 8; but the device may alternatively be pneumatically, hydraulically or mechanically operated. When solenoid 8 is energised pawl 15 is moved into engagement with one of a series of perforations 13 in a blade 12 to which a safety belt 4 is connected, the other end of the belt being secured to the solenoid 8 the blade being normally slidable with respect to anchored base plate 10 but on engagement of pawl 8 being locked against movement and thus the belt 4 against extension. Tension springs 19 and 20 normally has the pawl 15 out of engagement with blade 12 and the belt 4 to a fully retracted position respectively. In the embodiment of Figs. 4 and 5 (not shown) a releasable spring clip (43) links the blade 12 and the plate 10 such that they are released from one another if the belt 4 is subjected to an excessive force. As in Figs. 6 and 7 (not shown) the system may be used with a belt reel, the solenoid 8 being energised to move a plate (34) to lock the reel against rotation. Reference has been directed by the Comptroller to Specification 1,078,944.

Abstract: 1290667 Heating and cooling buildings ANDREWS-WEATHERFOIL Ltd G T K DEAN and R W PUZYNA 28 Nov 1969 [29 Nov 1968] 56928/68 Heading F4U and F4V] In order to suit the heating or cooling capability of a building to the room or rooms below a false ceiling, panels of the ceiling are removable to allow heat exchange surfaces and air circulating units be be associated with different parts of a heating or cooling network located in the ceiling void. As illustrated, the ceiling panels are supported by a system of rods 22 which form pyramidal modules, each row of which is served by a hot water pipe 26 and a vitiated air extraction pipe 27. A ceiling panel may be removed to allow a pipe 32 and fins 33, formed in three separate segments, to be fixed on the pipe 26 clamps 38 to thereby form a heat exchanger. The heat exchanger is then enclosed within a unit 30 which has openings 40 and 41 communicating with the ceiling void, a duct 47 communicating with a vitiated air duct 27, a duct 42 with a fan 45 for feeding air to the room, and a duct 43 for taking air from the room. A sliding damper 49 determines the function of the unit. In the illustrated position, room air is recirculated and heated. If the damper is moved fully to the left, Fig. 4 (not shown), fresh air from the ceiling void passes from the opening 40 to the duct 42 without being heated, and room air overflows through the duct 43 to the vitiated air duct. If the damper is in an intermediate .position, Fig. 3 (not shown), fresh air from the opening 41 is heated and passed to the room, and vitiated air is extracted. The damper is manually operated, and then the unit is used to heat the room, the fan45isthermostatically operated. The ducts 42 and 43 include flaps, Fig. 6 (not shown), which close in the event of fire. The unit casing is moulded from plastics material. The extractor ducts 27 are formed of plastics sheets stretched over a wire frame and have sleeves or slots for communication with the unit ducts 47. In an alternative construction, Fig. 11 (not shown), the ducts 27 are hung from horizontal clips and weighted by internal rods. In an alternative form of unit, Figs. 12 and 13 (not shown), there are two fans, one of which operates when ventilation alone is required, and the other of which operates when heating is required. The vitiated air duct and the fresh air entry to the other fan are controlled by flaps. In a further form of unit, Fig. 14 (not shown), a butterfly valve determines whether fresh or recirculated air is fed to the unit, and the heat exchange surfaces have a flap controlled air flow by-pass. An arrangement may be adopted in which the vitiated air is free within the ceiling void and the fresh air is ducted to the units. If there are fire or smoke barriers within the void; they have apertures which are closed automatically in the event of fire. Air ducts passing through the barriers are clad with fireproof material.
