摘要： A process for the production of a shaped article of a ceramic material in which a composition comprising particulate ceramic material and a liquid medium is shaped, the liquid medium is removed from the shaped composition, and the composition is heated to sinter the particles of ceramic material in which the composition is subjected to high shear mixing such that in the shaped article which is produced the mean maximum size of flaw is less than 25 microns. Also, a shaped article of sintered particulate ceramic material in which the mean maximum size of flaw is less than 25 microns and in which the minimum dimension of the shaped article is in excess of 0.1 mm.

摘要： A method is provided for treating cooking oil during frying operations, which comprises in situ treatment of the oil with a source of calcium or magnesium combined with silicate such that the calcium or magnesium substantially does not leach into the oil. The filter treatment materials may be cement clinker, OPC, calcium silicate and combinations or mixtures thereof e.g. a combination of white OPC clinker and white OPC. The filter treatment materials may be in the form of a free briquette or block immersed in the oil. In other embodiments a decontaminating or filter cartridge is provided for fitting to a deep oil or fat cooker or a frying basket and comprises a foraminous housing containing filtering or decontaminant material. The cartridge may be used in association with a deep oil or fat fryer having a base formed with a depression defining a cool spot, the cartridge fitting in or on said cool spot.

摘要： Systems for transmitting and/or receiving electromagnetic signal radiation are disclosed. The inventive systems are distinguished from previous such systems in that each includes at least one resonant cavity comprising a housing containing a body, e.g., a cylindrical or helical body, of relatively high T.sub.c superconducting material. Significantly, this body is fabricated using a new, unconventional procedure. As a result, the body exhibits substantially lower surface resistances than either previous such bodies of relatively high T.sub.c superconducting material, fabricated using conventional procedures, or bodies of copper, at 77 Kelvins and at frequencies ranging from about 10 MHz to about 2000 MHz. Moreover, as a consequence, the resonant cavity containing the unconventionally fabricated body exhibits much higher quality factors, Q, at the above temperature and frequencies, than previous such cavities containing either conventionally fabricated bodies of relatively high T.sub.c superconducting material, or bodies of copper.
