Abstract: 1,252,277. Evaporators, vapour-compression type; desalination of water. COMPAGNIE ELECTRO-MECANIQUE. 13 Nov., 1968 [15 Nov., 1967], No. 53930/68. Heading BIB. [Also in Division F1] Water, e.g. sea water, supplied through duct 45 is desalinated by distillation in vapourcompression evaporator 5 and multi-stage flash evaporator 4A, 4B, the compressor 3 of evaporator 5 being driven by steam turbine 2 which also drives an electric current generator 1 and exhausts steam to the heater 6 of the flash evaporator. The upper part of the flash evaporator is provided with condensers (not shown), and condensate (desalinated water) is withdrawn through line 29. Desalinated water is also withdrawn from the coil of evaporator 5. Regulation of evaporator 5 is effected by connecting its evaporation chamber to an enclosed space at a different pressure; in the embodiment shown, the chamber may be connected to one or more stages of evaporator 4 by means of duct 53 and valves 55. Valves may be provided in the inlet and outlet ducts of compressor 3 whereby the distribution of power between generator 1 and compressor 3 can be adjusted. By actuating the regulating devices rapidly, it is possible to operate the plant so that, for a short time, evaporator 5 becomes a "boiler" and compressor 3 acts as a "turbine". The vapourcompression evaporator may comprise more than one evaporation chamber, connected in parallel or in series; and the condenser for the compressed vapours can be inside one or more of the chambers. A gas turbine or diesel motor may be substituted in place of the steam turbine 2. It is mentioned that the multi-stage flash evaporator 4 may be replaced by a multiple-effect evaporator. It is stated that the electric generator could be of the plasma type in which heat energy is transformed directly into electric energy; in this case the compressor would be driven electrically.

Abstract: 1,253,027. Valves. HOPKINSONS Ltd. 27 Nov., 1968 [19 Sept., 1967], No. 42508/67. Heading F2V. [Also in Divisions G2-G3] A relief valve member is biased to a closed position by a main loading derived from torsion bars 21 engaging valve spindle 25 via lever 26 and by a removable supplementary loading applied by actuator 32 which may be pneumatic (Fig. 2) or electric (Fig. 4). With actuator shaft 33 raised, spring 36 expands into abutment with a stop member 34 rigidly connected with spring seat 29. In its expanded state, spring 36 retains a pre-compression such that, upon depression of shaft 33 to apply the supplementary loading, the spring acts initially as a rigid forcetransmitting link. Screw 40 determines the final magnitude of the supplementary loading. If actuator 32 fails in a load-applying position, the relief valve can still open by compressing spring 36. An actuator in the form of a doubleacting pneumatic ram can be controlled by a fluid logic circuit with pressure-sensing pilot valves (Fig. 3, see Divisions G2-G3). In Fig. 6 (not shown), a concentric helical spring replaces the torsion bars, and the actuator and its spring act on the valve stem via a lever. In Fig. 4, linear electric actuator 82 acts through lever 80 and pre-compressed spring 91. An electric circuit (Fig. 5, not shown) equivalent to Fig. 3 controls the actuator, the control mode being such as to apply the supplementary loading when the sensed pressure reaches a first level. The loading is subsequently removed if the pressure exceeds a second, upper level.

In the examples, polybutadiene is pre-grafted with styrene and acrylontrile in aqueous emulsion, further grafting with said monomers is carried out in aqueous suspension, using hydroxyethylcellulose as suspending agent and the resulting graft polymer may be blended with styrene-acrylonitrile copolymer, or a mixture thereof with a bulk-suspension polymerized ABS graft polymer.

In the embodiment of Fig. 1 which is for small taps, drive between the two portions is provided by the spring 3. An overload diaphragm spring 11 is provided in case the tap meets a solid object. It may be arranged that compressing of spring 11 prevents further axial movement of the shank or operates means to withdraw the tool holder. 0-rings 6, 8 allow transverse movement of portion 2 relative to shank 1 to allow for slight inaccuracies in alignment of the tap with a hole. In a further embodiment for larger taps, Fig. 3, drive between the portions is by a pins 16 and slots 15. Alternatively a splined connection could be provided. In another embodiment,.Fig. 4 (not shown), for even larger taps, portions 2 project into shank portions 1 and drive is by pins and slots.
