Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

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 The condensate is continually withdrawn from the condenser (254) both to maintain the vacuum and to stimulate continued mass transfer upwardly of the spent steam at high speed.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 method of fabricating a hollow jewellery object in which an electrically conductive coating is applied to part (18) of a non-conductive mandrel or mould (10), the coated mandrel being presented for a first dip into an electrolyte containing ions of a precious metal e.g. gold so that the said parts of the mandrel are coated with an initial deposit; the mandrel is then removed from the electrolyte and the previously uncoated portions (24) coated before the mould is again dipped in the or a different electrolyte to form an outer shell integral with the internal ribs (28) or points formed during the first dip. Thus the hollow jewellery object is internally strengthened by the ribs (28), though in an alternative embodiment the ribs can be replaced by individual upstanding projections in bas relief if these conform to the external profile required for the jewellery object. The invention also includes a hollow jewellery object formed by the method according to the invention.

One of the members can be pre-attached to the external surface of a sack neck i.e. prior to the sack being filled. In an alternative embodiment, the members can be retained about the neck of a (filled) sack by a strap forming the clamping means i.e. with a neck part held between the members; the device(s) components can then be stored separately from the sack(s), as can the device components.

The invention relates primarily to the field of grooving and cleaving precious stones and diamonds and all other types of hard and or brittle materials. The technical problem is that in making a groove on the stone or diamond or other piece of material to be cleaved in the present hand processes or other processes used it is extremely difficult and it takes a long time to make the groove in the correct place. It is also difficult and time consuming to make a narrow thin groove. The problem is solved in this invention by mounting the first stone or diamond or piece of material to be grooved and cleaved on a claw holder or other type of holder which is set on an adjustable device. The second stone or diamond or piece of material is mounted on a second holder with a thin edge standing out. This thin edge is then moved and adjusted to touch the first stone exactly at the point to be grooved and cleaved. By this means the groove is made only at the required position and because a thin edge (commonly found in sawn diamonds or stones is used) a narrow groove results and this leads to a high quality cleaving. The main uses of the invention are in increasing the production output of stone or diamond cleaving operations.

This invention is a part of the three dimensional construction system based on a basic module wherein horizontal, vertical and longitudinal sides have equal measurement, the center of each square face being the fixing point. The heavy duty corner bars together with the cross-bars which make the basic structure are used for both depth and width to carry heavy loads. The construction elements consist of multiplication of the basic module allowing building of complicated constructions by adding modules or half modules and without deviating form the modular concept.

A multi input arithmatic logic unit by combination of breaking down the inputs into several stages of bitwise processing followed by shifting of outputs according to the power of bits. This process may also be repeated or serially combined, combined with carry look ahead stages or used for producing modular units by introducing carry-in and carry outs. This may also be incorporated to process negative numbers, produce logical functions, multipliers, dividers, mathematical functions, control units, etc.

The invention relates primarily to the field of packaging goods etc. It also relates to compressive strength provision for boxes, columns and other load bearing situations. The technical problem is that packages, columns etc., crush or buckle under compressive loads. This problem is solved by the use of certain principles of physics in this invention which consists of using a circular, cylindrical or similar shaped device placed inside a square or similar shaped box or device with the object of increasing the compressive strength of the whole. The principal uses of the invention are in packaging tea, powders, liquids etc., in cartons or similar receptacles and also in building and civil construction works etc.

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.
