Title: Improvements in or relating to valve structures
Inventor: GODDEN THOMAS EDWARD
IPC: F16K31/52
Filed: 1954-01-12
Abstract: 796,313. Valves. ROTOL, Ltd. Dec. 17, 1954 [Jan. 12, 1954], No. 36433/56. Divided out of 796,312, [Group XXVI]. Class 135. A valve structure for use in the liquid metering device of Specification 796,312, comprises a housing having an inlet 61 to a chamber 30 from which an outlet to a manifold 22 is controlled by a spring-loaded check valve 31 so arranged that it opens in response to pressure in the chamber 30. At the upper end of the chamber 30 is a by-pass valve 34 controlling the flow of liquid to a by-pass port 62, and actuating means for the two valves is so arranged that they may be opened separately or together. The actuating means consists of an eccentric 41 on a manually adjustable shaft 42 and co-acting with an arcuate slot 43 cut in a member 44 which constitutes part of the stem of the valve 34. An actuating stem 57 for the valve 31 extends through the hollow stem 37 of the valve 34 to coact with a lever 58 housed within the part 44. The arrangement is such that when the shaft 42 is turned anticlockwise, as seen in Fig. 4, the eccentric engages the lever 58 and opens the valve 31 only. When the shaft is turned in the opposite direction the eccentric engages the lower side of the slot 43 to open the valve 34, and continued operation of the shaft in this direction causes the stem 37 of the valve 34 to engage the upper end of a stem 36 of the valve 31 and open that valve. The shaft 42 may also be operated by an electric actuator under the control of a switch responsive to the filling of a fuel tank.

Title: Process for the production of isonitrones
Filed: 1958-11-20
Abstract: Isonitrones, i.e. compounds containing the group <FORM:0847338/IV(b)/1> are prepared by reacting a Schiffs base or a mixture of primary amines and carbonyl compounds with an aldehyde-monoperacylate. The reaction preferably takes place in the temperature range -10 to +20 DEG  C. optionally in the presence of an inert organic solvent. In a preferred embodiment oxygen is passed into an aldehyde at -5 DEG  C. in the presence of a cobalt acetate catalyst to give a 30 to 40 % solution of the aldehyde monoperacylate in excess aldehyde and the primary amine is then added to this mixture, thus forming the Schiffs base in situ.  An extensive list of mono- and di-aldehydes, ketones, keto-aldehydes and primary amines which may be used is given.  In examples (1) methyl N-cyclohexyl isonitrone is prepared by adding cyclohexylamine to a solution of acetaldehyde-monoperacetate in acetaldehyde, (2) propyl N-cyclohexyl isonitrone is similarly prepared, (3) methyl-N-isopropyl-isonitrone is prepared by adding isopropylamine to a mixture of acetaldehyde and acetone containing ferric acetonylacetate and through which oxygen has been passed at -5 to 0 DEG  C.
