Patent GB-966536-A (GB)
Title: Purification of wet chlorine by electrostatic precipitation
Inventor: BETTS REGINALD ARTHUR
IPC: B03C3/60
Filed: 1962-08-09
Abstract: Wet chlorine is purified by passing it through an electrostatic precipitator having titanium discharge electrodes operated at a voltage which avoids spark-over.  Preferably the precipitator is operated at a voltage not exceeding 80% of the calculated spark-over voltage and if titanium wire discharge electrodes of less than 20 s.w.g. are used, not exceeding 70%; as an added safeguard, the electrodes may be proportioned so that their surface temperatures under spark-over conditions would not exceed 400  DEG C.  The discharge electrodes may be made of or coated with titanium or made of an alloy based on titanium and the precipitator may take the form of wire discharge electrodes disposed within tubes or between pairs of parallel collecting plates.  The discharge electrode wires may be provided with tensioning devices and a thermally-stable protective shield, e.g. a graphite bush, provided between the wires or wire supports and the surrounding structure.  The collecting electrodes are preferably made of a material having sufficient conductivity to prevent build-up of charge; this may be achieved by coating or treating the surface by irrigation or making the electrodes of plastic material containing a filler such as graphite or ebonite. Specification 883,876 is referred to.

Abstract: 267,469. Blem, E. C. March 15, 1926. [Convention date]. Switching-systems.-Ordinary load circuits e are fed from bus-bar d supplied by one or more of sources a, b, c, whereas circuit g, which should be maintained as long as possible, is fed from bus-bar f, which is normally connected through a drum n to the bus-bar d. Should the bus-bar d be cut-out, an electromagnet t is de-energized, and the associated pawl allows the drum n to rotate under the action of a weight a to connect the bus-bar f successively to the sources a, b, c until an active source is connected, whereupon the electromagnet is re-energized and holds the drum in position. Instead of the load current passing through the drum contacts it may pass through contactors, the energizing circuits of which are controlled by the drum. Alternatively the drum may be rotated by a spring, by an electric motor supplied by a battery or by a compressed air motor, and in the latter cases the electromagnet t (ontrols the motor.

Title: Apparatus for insulating against conductive convective and radiant heat transmission
IPC: E06B9/00
Filed: 1977-08-01
Abstract: An apparatus for insulating against conductive, convective, and radiant heat transmission comprises a plurality of substantially non-transparent and generally parallel sheets. The sheets may be attached to a retracting device from which they can be drawn to extend and cover a building opening such as a window or onto which they can be retracted to uncover the opening. A number of spacers which may be in the form of collapsible or nestable devices are mounted within the apparatus to separate each pair of adjacent sheets and, thus, define a dead air space therebetween. At least one of the sheets has a surface, facing on the dead air space, that exhibits a low surface emittance. This surface emittance is sufficiently low to yield a total effective emissivity of the surface and dead air space of no greater than 0.60. Importantly, the spacer devices are designed so as not to abrade or otherwise harm the reflective surface. The combination of these dead air spaces with the low emittance surface synergistically results in an apparatus having low total effective emissivity that effectively impedes radiant heat transfer. The dead air spaces also effectively impede conductive and convective heat transfer.
