Title: Improvements in or relating to the technical hydrolysis of thiocyanic acid or salts thereof
IPC: C01C1/245
Filed: 1930-07-08
Abstract: In the production of ammonium salts by the hydrolysis of thiocyanic acid or its salts by means of dilute acids or mixtures thereof, the reaction is carried out with the addition of a salt which is not capable of decomposition by the acid present under the conditions of the reaction.  The attack of the liquors on the metallic apparatus employed is thereby reduced.  Ammonium thiocyanate may be hydrolysed by sulphuric acid, salts such as ammonium sulphate or sodium sulphate being added.  If phosphoric acid is employed such as ammonium phosphate or sodium chloride may be used.  It is preferable to construct the apparatus employed, wholly or in part, of molybdenum steel or to line the apparatus with this material.  According to an example ammonium thiocyanate is heated with sulphuric acid and ammonium sulphate liquor for several hours at 150-180 DEG  C. in an autoclave consisting of chromium nickel steel containing molybdenum. Ammonium sulphate is produced.

Title: Automatic device for cutting off tube sections from glass tubes
IPC: C03B33/095
Filed: 1964-05-25
Abstract: <PICT:1006925/C1/1> <PICT:1006925/C1/2> In an apparatus for cutting up glass tubing, a device lifts the lowest of a number of tubes in a sloping magazine and deposits it on a horizontal support whereon it is fed axially to an end stop spaced from the cutter, the severed piece being then transported away and the remainder again fed forward to the stop.  A supply of tubing is placed in the magazine 4 and the first is lifted by an element 6 having a notched extension 11 by which the tube is located between pairs of a series of rollers 2. A stop 33 is raised to hold the tube in position for the end to be removed by a burner and cool roller 13.  The stop is then retracted and causes the activation of an electromagnet 20 to raise a roller 16 into contact with the tube and feed it forward to a stop 14 adjustable to control the length to be cut off.  Engagement of the stop causes de-energization of the magnet 20 and withdrawal of the roller 16.  A driving roller 23 under the control of a roller 28 is then lowered into contact with the tube to rotate it while cutting is taking place.  The cut piece falls on to a delivery shoot 15, thus allowing the stop 14 to re-energize the magnet 20 and raise the roller 16.  When the length of tube has been reduced so that its end is no longer engaged by contact 29, a cam 10 is operated to raise the element 6 and the stop 33.
