Abstract: System for the fabrication, from marble, stone, alabaster, granite or the like, of spheres, eggs, especially those of round shape, also columns, hourglasses, etc., without locking of the workpiece, without back centres, without the need for centring. The system is composed of rollers or wheels, including those independent of each other, and which are appropriately shaped according to the type of object being worked; they cause the piece of cylindrical material to rotate, this being simply placed on them; while the cylinder of material is turning, dragged by the rollers or wheels, the appropriately shaped grinding stone advances and sculpts it, giving it the desired shape. The system can also be used for grinding and polishing of rough-finished objects, in place of the grinding stone there being brushes, rotating abrasive belts, abrasive stones, abrasive sponges or the like. We have produced prototypes which function perfectly. <IMAGE>

Title: Method of manufacturing the filamentary nanostructure
Inventor: IOISER ANATOL
IPC: B82B1/00
Filed: 2009-12-23
Abstract: The invention relates to electronics, in particular to the technology of manufacturing materials used in electronics and instrument engineering, namely to the ordered composite nanostructures. The method of manufacturing the filamentary nanostructure includes the manufacture of a workpiece blank by assembling a bundle of microwire segments each in glass insulation, placement of bundle inside a glass ampoule, vacuumization and sealing thereof and compression of bundle by heating to the ampoule walls softening temperature, thinning of the workpiece blank by its pulling up to the obtaining of the filamentary nanostructure with nanowires at a temperature above the temperature of softening of all glass components and of melting of microwires in the working filamentary nanostructure formation zone, and its subsequent cooling. Thinning of the workpiece blank is performed by consecutive pulling thereof in several cycles, at the same time its pulling during one cycle is carried out under the action of a constant force and a constant temperature, so that the ratio of this force to the viscosity of the glass at the bottom of the workpiece blank working heating zone may stepwise decrease from cycle to cycle proportional to the decrease of the pulled workpiece blank diameter square.

Title: System for controlling delays of luminance components
IPC: H04N9/64
Filed: 1980-01-09
Abstract: In a dual-standard PAL/SECAM color TV receiver, an identification system provides a mode-switching output, permitting automatic switching of the receiver between a PAL-reception mode of operation and a SECAM-reception operating mode, in dependence upon the PAL or SECAM nature of the transmission received. In the SECAM-reception mode, a PAL decoder receives the chrominance component output of a SECAM-PAL transcoder; in the PAL-reception mode, the PAL decoder receives chrominance signals which bypass the transcoder. Luminance signal channel of the dual-standard receiver includes a switchable luminance signal delay line in cascade with a chrominance component trap circuit. Switchable delay line is controlled by mode-switching output of identification system such that delay line is interposed in luminance signal path only during SECAM-reception mode operation. Delay magnitude provided by delay line substantially matches difference in delays suffered by chrominance information during operation in the respective modes. Trap circuit, providing luminance delay substantially compensating delay suffered by chrominance information during operation in PAL-reception mode, includes resonant circuits tuned respectively to upper and lower SECAM subcarrier resting frequencies.

Abstract: A mains water filter comprises sand and activated carbon to remove pesticides. The carbon may be mixed with sand or may form a layer 3 sandwiched between upper and lower layers 4, 5 of sand. The carbon may be loose or contained in textile bags, which may be internally divided and are placed on the lower sand layer. The filter forms a large rectangular bed with an overhead gantry carrying means for levelling the layers as they are applied and possibly for progressively removing sections of the upper layer as they clog, until the overall bed thickness is so reduced that the bed must be replaced. <IMAGE>
