Abstract: The invention comprises compounds of the general formula <FORM:1121110/C2/1> wherein Y is -NO2, -CN, -SCN, R5-CO -N(R6)-, R7-COO-, or (R8O)2PS-S-, R and R1 are each C1- 4 alkyl, at least one being alkyl, R2- 7 are each H or C1- 4 alkyl, R8 is alkyl, or R and R1 or R1 and R2 may complete an aliphatic carbocyclic ring containing 4-7 ring atoms. When R and R1 are both alkyl, one or more of the H atoms or one only of the alkyl groups may be substituted.  The aliphatic carbocyclic rings completed by R+R1 or R1+R2 may be substituted.  Compounds in which R3 is CH3 and R4 is H may be prepared by reacting an oxime of the formula <FORM:1121110/C2/2> with CH3NCO.  The compounds generally may be prepared by reacting an oxime of the above formula with COCl2 to form a chloroformate which is then reacted with NH3 or an amine HNR3R4.  2 - Formamido - 2 - methylpropionaldehyde oxime is obtained by reacting 2-amino-2-methylpropionaldehyde oxime with vinyl formate.  2 - Methyl - 2 - (O,O1 - diethylthionophosphonothio) - propionaldehyde oxime is obtained by reacting O,O1-diethyldithiophosphoric acid and NaOH with 2-chloro-2-methyl-1-nitrosopropane dimer.ALSO:Pesticidal compositions comprise a carrier and/or diluent and, as the active toxicant, a compound of the formula:  <FORM:1121110/A5-A6/1> wherein Y is -NO2, -CN, -SCN, R5 -CO-N(R6)-, R7 -COO-, or (R8O)2 PS-S-, R and R1-7 are each H or C1-4 alkyl, at least one of R and R1 being alkyl, R8 is alkyl, or R and R1 or R1 and R2 may complete an aliphatic carboxylic ring containing 4-7 ring atoms.  When R and R1 are both alkyl, one or more of the H atoms on one only of these two alkyl groups may be substituted.  When R+R1 or R1+R2 complete a ring, the ring may be substituted. The compositions may be used as insecticides, acaricides or nematocides and are formulated accordingly.  The compositions may contain surface-active, emulsifying and dispersing agents. Synergists may be added, the most effective being those known to synergise carbamate pesticides, in particular, pyeronyl butoxide, methylenedionyphenyl compounds, and 2-(3, 5-dichloro-2-biphenylyloxy)-triethylamine.

At least the surface of the cathode may consist of Cd, Pb, solid amalgam of Pb, or an alloy of Pb with Ag, Sb, Sn or Bi. The anode may consist of Pt, platinized Ti, graphite, Pb or its alloy, e.g. with Ag, Sb or Sn. The anolyte may be an aqueous solution of sulphuric or phosphoric acid. Oxalic acid may be added continuously to the catholyte which is withdrawn continuously to extract the glyoxylic acid. Thus cooling the withdrawn catholyte below 8 C. precipitates oxalic acid. The anolyte may circulate in a manner similar to that of the catholyte so that the pressure either side of the diaphragm is the same. At least one of the compartments may contain a woven fabric or grid spacer.

The hot gas from the gas turbine engine is conveyed via a duct 37 to a dispersal device 35 positioned above the heat exchanger 34 and shown as consisting of a hollow chamber with perforations 35A in its upper wall. From the dispersal device 35 the hot gas passes via the openings 35A into the cooling air stream within the tower.
