Abstract: ABSTRACT           A method and apparatus are provided for the electrostatic deposition of solid particles or liquid droplets on to an earthed surface.          The method involves in the vicinity of the surface to be treated directing a flow of gas carrying electrically charged particulate material adjacent a capacitor surface which has been charged to a high potential by the transference of electric charges developed on another particulate material which is being transported round a closed circuit path including a charging region remote from where the charge is transferred to the capacitor.  Charging of both particulate materials is preferably by triboelectricity although corona discharge may also be used.           Apparatus comprises tubing forming a closed loop, a compressor for circulating airborne powder round the loop, a corona discharge needle projecting through an insulated portion of the tubing wall and electrically connected to a toroidal capacitor surrounding said insulated portion and a barrel associated with a second compressor for projecting a separate supply of airborne powder adjacent the capacitor surface.           The invention is particularly suitable for crop spraying or dusting or the electrostatic coating of products e.g. with plastics, and represents a more efficient and thus improved method over known processes.

Abstract: CONCRETE WALL FORM SEAL MEMBER                Abstract of the Disclosure A seal member is provided for use in concrete wall form construction which sealingly engages with a form bore through which a tie rod supporting the seal member passes so as to prevent leakage of wet concrete from the form.  The seal member comprises a cylindrical member which is radially expanded into sealing engagement with the form bore by means of a partly tapered seal element in the form of an off-set retainer core.  Sealing is automatically achieved by means of the seal member to be axially moved by the form wedges during locking up of the form.  Alternate embodiments provide a radially expanding seal, which is expanded by axial movement of the seal member, as well as an off-set retainer core.  The offset enables the frustoconically shaped cones or insert members to function both to form a depression in the cast concrete, as well as to serve as spreaders for location of the wall forms.  Additional embodiments provide a rubber ring seal, together with shield members; yet another embodiment provides a sealing sleeve.

Abstract: CONTROLLABLE GAIN SIGNAL AMPLIFIER                Abstract of the Disclosure A signal amplifier is supplied with input signals at its base electrode and also is supplied at its emitter with quiescent operating current from a current source.          Amplified output signals developed at the collector of the amplifier are coupled to a transistor diode current splitter.  The relative division of current in the splitter is controlled by coupling a variable direct current supply to the diode.  The latter supply comprises a source of direct voltage, a variable resistive voltage divider coupled across the voltage source, and the combination of a voltage follower stage, a first series resistor coupled between the resistive divider and the input of the voltage follower and a second resistor coupled between the output of the follower and the diode. Gain controlled push-pull output signals may be provided by differentially coupling a second amplifier device to the first and coupling the output of a second current splitter to the second amplifier.          The second current splitter is then also controlled by the same current source as the first.
