    • A personal identification system wherein an encoded version of the user's fingerprint is reprint and recorded on an identification card or device; this encoded version is security machine-read and directly compared at the time of use with an impression of the fingerprint on a different but designated area of the card, or alternatively on a designated area of the machine-reader or a separate card, the comparison being done on a one-to-one basis so as to reduce the need for a large memory or storage capacity for fingerprint records on the card or in the security machine-reader. The personal identification system can be used with passports, travellers cheques, credit cards, cheque cards and the like.

    • A steam plant which includes a steam driven turbine (237), and a condenser (254) in which the steam exhausted from the turbine is condensed, the condenser (254) being at least 200 metres above the level of the turbine (237) and preferably several kilometres above the turbine level. The turbine (237) is connected to the condenser (254) by a vacuum tight shaft (252) adapted to convey the spent steam upwardly to the condenser at vapour speeds up to 0.75 of the speed of sound in that vapour. The condensate is continually withdrawn from the condenser (254) both to maintain the vacuum and to stimulate continued mass transfer upwardly of the spent steam at high speed.

    • A diamond sawing process, in which guidelines on the outer surface of a rough diamond are used for the sawing of up to six pyramid shapes (340) as fragments from a particular piece of tetrahedron shaped (sawable) diamond, whereby the maximum weight of a polished round brilliant cut (or other round cut diamond) is obtained from a particular rough diamond, together with the fragments. A marking pen or equivalent is held parallel to the centre line of the diamond (300), and adjusted so that its point (330) touches the shortest side of the diamond; when the diamond is rotated relative to the point, a circle is marked which represents the maximum round diameter that can be cut for that diamond. The pen crosses the ridges (412, 414, 416, 418) of the diamond, and these crossing points define the starting point of sawing. In a further refinement, the marker pen and its point can also be used to mark the maximum height of the fashioned diamond, these marks being placed on the ridges, and a pyramid shape cut from one or both of the top and bottom (culet) of the rough diamond. Preferably, a laser can be used both to mark and saw the diamond in one operation, thereby saving time and the possible need for readjustment or resetting of the diamond on its fixing.
    • 金刚石锯切工艺,其中使用粗糙金刚石的外表面上的指南用于从特定的四面体(可锯齿)金刚石的碎片切割多达六个金字塔形状(340),由此最大重量 与特定的粗钻石一起,与碎片一起获得抛光圆形明亮切割(或其他圆形切割钻石)。 标记笔或等同物平行于金刚石(300)的中心线保持,并被调整为使其点(330)接触钻石的最短边; 当钻石相对于该点旋转时,标记出圆圈,其表示可以为该钻石切割的最大圆直径。 笔穿过钻石的脊(412,414,416,418),这些交叉点限定锯切的起点。 在进一步的改进中,标记笔及其点也可以用于标记形状的金刚石的最大高度,这些标记被放置在脊上,并且从顶部和底部(底部)中的一个或两个切割出的金字塔形状, 的粗钻石。 优选地,可以在一次操作中使用激光来标记和观察金刚石,从而节省时间,以及可能需要在其固定时重新调整或重置钻石。

    • In this invention 'Sea Bed Fractured Power Production Systems' are constructed in the sea where Updraft Wells (UW1) are drilled into the sea bed and are surrounded by Boreholes (BH1) also drilled down to the required depths and at the aforesaid required depth the rocks in the earth's mantle/crust/core are fractured by blasting with explosives to create a Rock Fractured Area (RFA1). These Boreholes (BH1) are fitted with Pipes (P1) and One Way valves (OV1) so that seawater which is under high pressure, equivalent to the sea bed depth below the sea surface level at that point, gets forced down into the Rock Fractured Area (RFA1). This heated seawater then flows up under high pressure through Updraft Wells (UW1). The seawater flowing out of the Updraft Wells (UW1) is at a higher temperature than the surrounding seawater of the ocean and therefore rises towards the sea surface level. One or more Floating Covers (FC1) are positioned above the Updraft Wells (UW1), to capture the heated seawater as it exits the Updraft Wells (UW1) and to direct this flow upwards. One or more Flexible Tubes (FT1) with opened mouths are fitted to the Floating Covers (FC1), at or near their center or at a suitable position. These Tubes are extended to the sea surface level and their top ends are with opened mouths and are connected to one or more Basins (B1) floating at or on or near the sea surface, where the Basins (B1) are fitted with One Way valves (OV1) so that the heated seawater flows out of the Basins (B1) into the sea when the One Way valves (OV1) are opened. This outflow of heated seawater sucks up seawater flowing out of the Updraft Wells (UW1) and creates a flow through the Flexible Tubes (FT1). Turbines/Generators (TG1) are optimally positioned, within the Flexible Tubes (FT1) to produce electricity.
    • 在本发明中,“海床断裂发电生产系统”是在海床中兴建的“海床裂缝电力生产系统”(UWB)在海床中钻探的,并被钻孔(BH1)包围,钻孔深度达到所需的深度,并在上述所需的深度 地球的地幔/地壳/岩心中的岩石被爆炸物破碎而形成岩石破裂区域(RFA1)。 这些钻孔(BH1)配有管道(P1)和单向阀(OV1),使得处于高压下的海水相当于该点处海平面以下的海床深度被迫下入岩石断裂 面积(RFA1)。 然后,这种加热的海水通过Updraft Wells(UW1)在高压下流动。 从“浮世界”(UW1)流出的海水比海洋周围的海水温度高,因此向海平面上升。 一个或多个浮动盖(FC1)位于Updraft Wells(UW1)上方,以便在离开Updraft Wells(UW1)时捕获加热的海水并将其向上引导。 一个或多个具有开口的柔性管(FT1)安装在浮动盖(FC1)上,在其中心处或其附近或合适的位置。 这些管延伸到海面,其顶端是敞开的嘴,并连接到一个或多个浮在海面上或附近的盆(B1),其中盆(B1)装有单向阀 (OV1),使得当单向阀(OV1)打开时,加热的海水从盆(B1)流出大海。 加热的海水的这种流出吸收了从“移动井”(UW1)流出的海水,并通过柔性管(FT1)产生流动。 涡轮机/发电机(TG1)在柔性管(FT1)内位置最佳,以产生电力。
