Title: Improvements in Snap Action Switches
Inventor: BURCH LYNDON WALKUP
IPC: H01H23/20
Filed: 1967-07-25
Abstract: 1,199,957. Snap action switches. L. W. and H. K. BURCH. 26 July, 1967 [25 July, 1966], No. 34068/67. Heading H1N. On movement of snap action contact blade 52 to the left it is snapped overcentre by the camming action of a ridge 76 of casing 12 on a contact 60 on the blade and engages a metal plate 20 secured to a conducting support 16 for the actuating member e.g. lever 30, of the snap action blade 52. Continued movement in the same direction causes a camming surface 25 of plate 20 to snap the blade 52 overcentre so that contact 60 engages a fixed contact 72 and completes a circuit between terminal 9 and a terminal secured to the support 16 of the lever 30. Overtravel movement from this position causes the contacts 60, 64 carried by the blade 52 to be jammed between the camming surface 25 and the fixed contact 72 and a contact cylinder 44 carried by the lever 30 to engage a fixed auxiliary contact 77 electrically connected to the fixed contact 72 so that a circuit in shunt with the first mentioned circuit is completed between the terminal 9 and the terminal secured to support 16. Since the contact cylinder 44, which carries the centre legs of snap action blade spring 52, is directly secured to conducting lever 30, the shunt circuit will be completed even if the snapaction blade 52 is destroyed. The lever 30 moves against the action of an overcentre spring 38.
Patent GB-1017447-A (GB)
Title: Purification of pyrrolidone
IPC: C07D201/16
Filed: 1962-09-05
Abstract: Polypyrrolidone is produced from pyrrolidene from which contaminants including 1-(1-pyrrolin-2-yl)-2-pyrrolidon have been removed by distillation and by treatment with water followed by drying. Examples 3 and 4 describe the polymerization using sodium pyrrolidene as the catalyst and phenyl isocyanate (3), and butyrolactone (4) as activators.ALSO:A contaminant, 1-(1-pyrrolin-2-yl)-2-pyrrolidone, is removed from pyrrolidone by hydrolysis with water.  The pyrrolinyl-pyrrolidone is present in amounts of 0.1-0.3 mole per cent. Pyrrolidone is treated preferably with 3-10% by weight of water and especially 5-8% for a preferred reaction time of 1/4 -16 hours in the temperature range 80-200 DEG  C. and particularly 130-170 DEG  C. The hydrolysis is catalysed by acids, e.g. hydrochloric, sulphuric, perchloric and trichloroacetic acids.  The hydrolysis is maintained until less than 0.07% by weight of the contaminant remains.  The pyrrolidone may then be treated to remove any acid present and the excess of water removed by distillation. In order to prevent the reformation of pyrrolinyl-pyrrolidone during distillation it is preferred that the temperature is not kept above 120 DEG  C. for more than about an hour.  Continuous and azeotropic distillations are useful. Pyrrolinyl-pyrrolidone acts as an activator in the polymerization of pyrrolidone and pyrrolidone purified by the process of the invention is thus suited for polymerization (see Division C3).
