Abstract: A solid pesticidal composition, particularly suitable for application on walls, ceilings, floors or other absorbent surfaces, comprises a pesticidal agent and a fusible water-insolubilisation resin compatible therewith, the pesticidal agent having the general formula <FORM:1070026/A5-A6/1> in which R and R1 are the same or different and each is a saturated linear- or branched-chain alkyl radical having from 1 to 4 carbon atoms and R2 is hydrogen or a linear- or branched-chain alkyl radical having from 1 to 4 carbon atoms. Suitable resins include hpenolic, terpenic, terpene phenolic, cumaronic and cumarone indenic resins, and modified colophonium having a softening point of from 80 to 120 DEG C.  The composition may also contain fillers (e.g. diatomaceous earth, talc, clay or bentonite) and surface active agents (e.g. alkali metal or alkaline earth metal arylakyl-sulphonates and condensation products of ethylene oxide with fatty acids or alkylphenols).  In the examples, the pesticidal agent employed is the amide, monomethylamide, monoethylamide or monoisopropylamide of O,O-diemthyl-dithiophosphorylacetic acid.  In some examples, the composition also contains the O,O-diethyl-dithiophosphoric ester of 3,4-tetramethylene rembelliferone.  Tests are described which show the efficiency of some of the compositions of the invention in killing flies.

Abstract: 744,426. Fluid-pressure servomotor-control systems. LAIDLAW, A. B. S., and EADIE, G. P. Sept. 7, 1954 [Sept. 7, 1953], No. 24741/53. Addition to 703,353. Class 135. In regulating means for maintaining a predetermined relationship between the fuel and combustion air supplies to a furnace, as claimed in the parent Specification, the rotatable element is a cam or low plate 10 connected to one of the pressure-responsive members 1 and a cam follower 15 contacts a portion of the plate's edge having a curvature dependent on the predetermined relationship and is connected, e.g. by links 17, 20, 25, to the other pressure responsive member 26 which is a float responsive to the air pressure. Fuel pressure acting on the diaphragm 1 and through lever 3 moves a piston valve 6 to actuate a toothed quadrant 7 for positioning the plate 10 and which recentres the valve 6 via spring 14. The plate 10, through follower 15 and link 20, positions the piston valve 23 controlling pneumatic or hydraulic fluid to a power cylinder 28 which controls the admission of power fluid to a regulator controlling combustion air pressure.

In the central position shown the inlet is open to both outlets and either of which may be closed by rocking the member 36 in the plane containing the outlets whilst such movement in a plane at right angles thereto does not cause movement of the member 36. The latter has compressible washers at each end and the spindle 37 is supported through a part-spherical collar 41. In a modification, the inlet leads to a chamber 51, Fig. 7, from which open outlets 55, each controlled by a piston 56; the two latter are connected by a lever 58 on a rocking shaft 59.

The spindle, which carries an operating cross bar 74, incorporates a fork 75 which co-operates with the bar 69 to allow one valve to close as the spindle is rotated. The valves may throttle instead of cutting-off fluid flow.

Measuring-apparatus comprises an instrument having a semi-conductor member sensitive to a magnetic field as in the parent Specification, and in which a current to be measured is arranged to vary the magnetic field. In Fig. 1, a body 1 of indium antimonide or other Am Bv compound in a bridge circuit is fed with alternating current. The output of the bridge is applied via transformer 6, bridge rectifier and terminals 10, 11, to a direct current measuring instrument. Conductor 2 carrying the current to be measured is placed adjacent body 1, and the change in resistance of body 1 due to the magnetic field surrounding conductor 2 enables the current to be measured. In an alternative arrangement, the Hall effect output from the body is used instead of the change of resistance, to indicate the magnitude of the adjacent current. In this example, alternating current is applied to the body 1 via a choking coil having a core with rectangular magnetization loop, so that a rectangular constant current flows through the body regardless of variations in supply voltage. Specification 719,873 also is referred to.

As shown, the kiln 1 comprises a drying and heating zone Z-1, reduction zone Z-2 and cooling zone Z-3, ore being fed from the container B through the control gate C by screw conveyer 9. A burner 12 delivers into a combustion chamber 14 arranged at the discharge end of the kiln, combustion taking place out of contact with the ore which passes through the ports in the ring 18 to the cooling zone Z-3 formed by the annular water-cooled chamber surrounding the combustion chamber and from which the material is directed to the central discharge aperture 15 by the spiral blading 24. The ends of the kiln are supported by pivoted members 35 urged towards the kiln by springs 23, the discharge end being sealed by housing 21 and provided with sealing' rings 22, 22A and 32, 32A and a resilient packing ring 36 which provides pressure between the rings 32, 32A and also prevents escape of gas between the sealing ring 32A and sleeve 28 of the discharge housing. Combustion gases are prevented from entering the cooling chamber through the ported ring 18 by the introduction of a controlled atmosphere into the chamber at 19. The escape of waste gases to an offtake 7 is controlled by a damper 8 a supplementary air pipe 10 and conveyer 9 extending through the damper which is adjusted to maintain a positive gas pressure in the kiln in order to prevent infiltration of air. Heat transfer chains D and lifters 26 are provided. The sections of the kiln defining the zones Z-1 and Z-2 are lined with insulating brick 2, having an apparent specific gravity between 0.5 and 1.25.
