Title: Improvements in biocidal compositions
Inventor: TINCKNELL RAYMOND CHARLES
IPC: A01N25/04
Filed: 1950-08-09
Abstract: An aqueous dispersion of a herbicide, fungicide, insecticide or other biocidal compound, suitable for the treatment of plants or soil, contains a dispersing agent composed in part of a volatile element the removal of which from the dispersing agent would cause the dispersion to break, so that after application of the dispersion the volatile element of the dispersing agent evaporates leaving behind a residue less easily removable by water.  The preferred dispersing agent is a mixture of a petroleum sulphonate (mahogany soap) and an adequately volatile alcohol. The alcohol may be n-butanol, ethanol, iso-propanol, n-amyl alcohol, octyl alcohol, or cyclohexanol. Biocidal substances referred to are pentachlorophenol, D.D.T., parathion, hexachlorocyclohexane, p-nitrophenol or an ester of 2:4-dichlorophenoxyacetic acid.  These substances may be dissolved in a hydrocarbon oil so that the resulting dispersion is an emulsion in water.  The invention covers compositions containing no, or a part of the water, which can be mixed with water to form the dispersion.

Abstract: 786,910. Photo-electric control. ELESTA, Ltd. July 15,1955 [Nov. 9, 1954], No. 20611/55. Class 40 (3). [Also in Group XI] In an electric flame controller for supervizing liquid or gaseous fuel burners having a lightsensitive element 6, such as a cadmium sulphide crystal, for detecting the flame, an amplifier 2 for amplifying the voltages occurring at the light-sensitive element, relays for switching on ignition apparatus 21 and a motor 24 driving the fuel pump and blower, and means, such as a lamp 37, for indicating faults, the amplifier 2 has a cold cathode glow tube 12, the starter electrode 15 of which is controlled by the voltages at the light-sensitive element 6, an electromagnetic relay 3 having its winding 18 energized by the main discharge circuit of the cold cathode glow tube 12 effects the switching on of the ignition apparatus 21, a thermal delay relay 4 switches on the motor 24 a predetermined time after the energization of the ignition apparatus and a further thermal delay relay 5 disconnects the ignition apparatus and the motor if the burner does not ignite within a predetermined period and remains in this disconnecting condition until returned into the operating condition by a hand-operated actuator 35. The light-sensitive element 6 is included in a resistance network 8 ... 11, 17 connected to the starter electrode 15 and the cathode 13 of the glow tube 12 and arranged so that in the absence of a burner flame no discharge occurs between anode 14 and cathode 13. To start the burner, a mains switch 40 is closed to connect the mains supply 30 through thermostats 39 and closed contacts 33 of the second thermal relay 5 to the light-sensitive element 6 and the glow tube 12 and through the closed contacts 19 of the electromagnetic relay 3 to the ignition apparatus 21 and through the closed contacts 27 of the first thermal relay 4 to the heating winding 26 thereof. After a predetermined time the bimetal strip 25 of the first thermal relay 4 bends to open contacts 27 and close contacts 28 which energize the motor 24, whereby fuel and air are supplied to the burner. A current sufficient to keep the bimetal strip 25 bent is fed through a resistance 29 to the heating winding 26. The closed contacts 28 also energize through the closed contacts 20 of the electromagnetic relay 3, the heating winding 32 of the second thermal relay 5. If the burner ignites, the glow tube discharges to energize the electromagnetic relay 3 and both contacts 19, 20 open to de-energize the ignition apparatus and the heating winding 32 of the second thermal relay 5. If the burner fails to ignite, the bimetal element 31 of the second thermal relay 5 opens contacts 33 after a predetermined time to de-energize all the circuits described. It also closes contacts 34 to energize the lamp 37.
