Title: Magnesium alloy-impregnated coke for spher - cidal graphite prodn
IPC: C21C1/10
Filed: 1969-03-14
Abstract: Coke impregnated with magnesium alloys containing 1-10%, pref. 1-5% Li, Ca, Si or rare earth metals is suitable for treating molten iron to ensure the formation of graphite nodules. The presence of the alloying elements modifies the surface tension of the melt giving better impregnation of the coke and aids the removal of oxygen and sulphur from the molten iron. The coke is impregnated by heating to 800-1100 degrees C in a non-oxidising atmosphere and then immersing in the molten magnesium alloy bath at about 700 degrees C. It is introduced into the molten iron in the usual immersion bell. The process gives a high Mg yield and a relatively smooth and uniform treatment.

Title: Harvest weighing equipment - receives harvest in bin for weighing and transfers harvest to collectors
IPC: G01G13/00
Filed: 1973-10-29
Abstract: The harvest weighing equipment has a bin (2) which can receive the amount of harvest to be weighed.

Title: Uncoupling the drive of fabric take:up motion - as required by running conditions and when loom stops
Inventor: GOLFIER GASTON
IPC: D03D49/20
Filed: 1974-01-14
Abstract: A device in a loom for stopping the drive of the fabric take-up motion, is adaptable to motion of the type in which a finger lifts a pawl energised by a reciprocating mechanism, so that it turns a ratchet wheel step by step. According to its selection, the lifting finger is able to occupy an inactive position, away from the normal path of the pawl, and an active position in which it pushes the pawl away from its normal path, so that it does not engage with the ratchet wheel. The device for stopping thd drive of the take-up motion is arranged so that the lifting finger for the pawl is actuated through a mechanism energised in its turn in sequence with the running of the loom. This mechanism is controlled both by the electrical system regulating the running of the loom and by that for stopping the loom itself, so that the one or the other of the two necessary motions are effected which pivot the lifting finger into the active or the inactive position. A relatable arrangement fully capatable of standing up to the severe treatment it receives is produced.

Abstract: A catalyst for the polymn. of polyurethanes (and epoxy resin) precursors contains salts of amines with 1 or more tert. N atoms and carboxylic acids with an alpha-substit., which causes irreversible thermal decompsn. to the catalytically amine and CO2 to take place at 70-200 degrees. The salts are of formula: AH + OCO-CRR1 -nX (in which A is an amine; m is 1 or 2; R and R1 are hydrogen, (m)ethyl or aryl; n is 1 or 2, and X is -CN, -NO2, -COO, or -COCH3 if n = 1, or -SO-, -SO2- or -CO- if n = 2, in alpha-posn.). The catalysts give compsns. which have prolonged storage stability at room temp. but react on heating, due to quick and irreversible decompsn. of the salts, releasing the active amine.
