Title: Purifying molten metal
Inventor: KEEGAN NEIL J
IPC: B22D1/00
Filed: 1990-03-27
Abstract: ABSTRACT                      PURIFYING MOLTEN METAL           The  invention  relates  to a means  of  purifying molten  metal,   particularly  molten  steel   during  the continuous casting process.           The molten metal flows in a tundish (1) passed one or more protuberances (4, 5) in the longitudinal sidewalls of   the   tundish,   there   being   associated   with   the protuberances a partial barrier (8, 9) disposed towards the metal zone of arrival (6) and/or outlet (10), whereby the free-flow area of the tundish is reduced and metal flow velocity increased.            In a preferred embodiment the metal flows underneath a first partial  barrier,  between a pair of diametrically-opposed sidewall  protuberances  and  then  over  a  second  partial barrier.  The metal flow is thereby directed upwards so that it can come into contact with a surface-covering layer of flux to remove inclusions.

Title: Conveyor belt
Inventor: POERINK NIKOLAAS J
IPC: B65G15/30
Filed: 1990-05-10
Abstract: Abstract of the Disclosure A belt-like conveyor including at least two continuous chains which are parallel to one another and driven by sprocket wheels.          The chains have a number of overlapping chain links and a number of carrying bars which are disposed transversely to the chains to which the end pieces of the bars are also connected.  The end pieces of the bars also function as pins for the chain links while penetrating two of the latter and the remaining part of the carrying bars between the two end pieces serve as a carrying area of the conveyor.  The carrying bars extend over the top of the chain links toward the exterior and end portions of the carrying bars are U-like bent toward the bottom and toward the inside and penetrate the chain links from the exterior, which permits an unimpeded lateral sliding on and off of pieces and which provides an enlarged carrying area and which is also suited for conveying heavy pieces while developing only a low surface pressure.

Title: Anti-caking coating and method for preparation thereof
Inventor: OZDOBA DALE M
IPC: A23K1/00
Filed: 1990-09-06
Abstract: ABSTRACT OF THE DISCLOSURE      A coating composition useful on a variety of substrates, and particularly as a coating for ammonium nitrate which exhibit a reduced tendency to cake or dust once applied to the surface of a substrate.  In one embodiment, the composition is composed  of magnesium stearate and an effective amount of magnesium oxide, i.e. 10-15% by total weight of the coating composition, to substantially minimize or reduce the tendency of the composition to cake or dust, particularly after the coating composition is applied to the substrate.  The composition preferably is colored by incorporating pigment in a reactant mixture of stearic acid and magnesium oxide before completion of the reaction.  As a result the pigment is entrapped in a matrix formed by the magnesium stearate and magnesium oxide so that discoloration by contact with the coating composition, for example on the coated substrate, does not readily occur.  The reaction is conducted in two stages:  in the first stage magnesium oxide, a relatively small amount of stearic acid, a reaction catalyst and water are mixed at about 75°C to uniformly disperse the magnesium oxide in the resultant slurry; then, in the second stage, the temperature is raised to 80-85°C and the balance of the stearic acid is added and reacted to form the desired reaction product composition of the present invention.  The pigment is added to the reaction mixture, preferably in the form of an aqueous surfactant solution, before completion of the reaction so as to become entrapped in a matrix formed by the magnesium stearate and magnesium oxide components of the reaction product composition.

Inventor: HENRY PATRICK T
IPC: G21C19/20
Filed: 1990-09-27
Abstract: Apparatus for remotely obtaining sample scrapings from the inner surface of a fuel channel of a nuclear reactor with coolant in the fuel channel. A sampling tool is introduced into a fuel channel. The sampling tool has a cylindrical casing in which are mounted cutters for obtaining the scrapings. Forward movement of a central shaft in the sampling tool actuates the cutters in sequence to project through a slot as they move forwards and the sample scrapings fall into sample receiving pockets in the sampling tool. A pusher having a cylindrical casing of substantially the same inner diameter as the inner diameter of the fuel channel has a floating plunger mechanism with a sliding internal housing mounting a plunger rearwardly biased in the housing. The ram head of a fuelling machine engages the trailing end of the plunger, moves the housing forwardly until it stops against the casing of the sampling tool and then advances the plunger to cause forward movement of the central shaft of the sampling. tool to obtain the scraping.      A preferred form of the apparatus obtains sample scrapings at desired orientations. For example, it obtains scrapings at desired ones of a 11:00 o'clock, 12:00 o'clock or 1:00 o'clock orientations. An orientation device is installed in the end of a fuel channel and it has a rotatable ring which may be rotated to one of three selectable positions corresponding to respective ones of the 11:00 o'clock, 12:00 o'clock and 1:00 o'clock orientations: A ring key on the orientation device cooperates with a keyway in the sampling tool to orient the sampling tool.
