Title: Composite refractory materials.
Inventor: GARVIE RONALD CHARLES
IPC: C04B35/58
Filed: 1987-08-14
Abstract: A relatively dense composite refractory material which has reasonable strength and good thermal shock resistance comprises a matrix refractory material within which are dispersed particles of a ceramic material. The ceramic material comprises from 1.0 to 40 per cent of the composite material. Each particle of ceramic material is an agglomerate of microcrystals which are strongly bonded together, which exhibit strong thermal expansion anisotropy and which have a size such that cracks do not form spontaneously within the agglomerates during cooling from about 1600 DEG C to room temperature. The ceramic material and the refractory material are mutually chemically inert in the temperature range in which the composite refractory material is to be used.

Abstract: When spatial movement of points to be measured is measured by means of ultrasonic signals, the problem is that disturbances frequently occur which can lead to a falsification of the measurement results. It is proposed to check the spatial area between the sound transmitter (13) and sound receiver (19) for freedom from obstacles by means of electromagnetic waves, particularly by means of light waves and/or not to use the ultrasonic signals whose transit time and/or amplitude are outside a predetermined expected range, for deriving the distances but to discard these signals.

Inventor: JOHNSON KENNETH P
IPC: C04B38/00
Filed: 1988-10-06
Abstract: Provided is a method of manufacturing sintered parts from particulate material, e.g., metal or ceramic parts. The method comprises mixing together predetermined amounts of powdered particulate material and a binder, which mixture is then molded under heat and pressure. The binder comprises at least a lower melting point component and a higher melting point component, with the lower melting point component remaining in a liquid state, becoming semi-solid or relatively soft upon cooling to ambient temperatures. Prior to sintering, the lower melting point component of the binder is selectively dissolved in a liquid solvent, and the higher melting point component is removed upon heating at temperatures below the sintering temperature. The result is a process which eliminates or prevents the formation of oxides, substantially reduces the time required for debinding and sintering, and essentially eliminates cracking in the finished part.

Abstract: For hardening shaped articles, especially casting moulds and cores made of moulding sand, the method employed is one in which a catalyst/air mixture is passed through a moulding compound (1), to which a curing binder has been added, and the gas mixture escaping from the mould is passed through an adsorption apparatus (16, 17) which separates the catalyst from the air stream. For recovery and reuse of the catalyst, the gas mixture escaping from the mould is passed in a cyclical sequence through two sorption columns (16, 17) arranged in series, until the sorbent of the first sorption column (16) is saturated, and the fresh air fed to the mould simultaneously flows through a sorption column (13) saturated in a previous cycle. For this purpose, the sorption columns are interchanged, with the result that, in a following cycle, the gas mixture escaping from the mould is passed first of all through the second sorption column connected downstream in the preceding cycle, and then through a sorption column desorbed in a preceding cycle. <IMAGE>
