Abstract: 1425825 Testing high voltage components F C ROBINSON & PARTNERS Ltd and  I A BLACK 6 Feb 1973 [10 Feb 1972] 6173/72 Heading G1U In order to test a high voltage component, such as a capacitor Cx, Fig. 1, for partial breakdown, the component is arranged in a circuit including a high voltage source S and two monitoring units Ml, M2, in such a way that spurious supply-borne transients cause a first combination of outputs  from the monitoring units - in Fig. 1 pulses of the same polarity - whereas a transient caused by a partial breakdown within the component under test causes a second combination of output from the monitoring units - in Fig. 1 pulses of opposite polarity - thereby allowing, by the use of an appropriate comparator CC, a gate G to be controlled so that it only passes partial breakdown transients to a display device D. The second capacitor Cb shown in Fig. 1 may be either a reference capacitor or a second capacitor under test - in which case partial breakdown transients cannot be ascribed to either capacitor. The principle of operation of the circuit is that a supply-borne transient will pass equally through the two capacitors, thereby causing pulses of similar polarity to be produced by the monitoring devices. Whereas a breakdown transient originating in one of the capacitors will cause a loop current to flow through both monitors thereby causing pulses of opposite polarity to be produced. In a modification Fig. 2 (not shown) supply-borne transients cause pulses of the same polarity but slightly displaced in time, and breakdown transients cause  pulses, also of the same polarity, but simultaneously in time.

Title: Improvements relating to furnace walls
IPC: F23M5/08
Filed: 1925-03-06
Abstract: 240,366. Helbig, A. B. March 6, 1925. Walls supported by cooling tubes are formed of fire-bricks spaced so that expansion may occur and held in place by an elastic cover on the rearward side of the tubes. The fire-bricks 2 have rearwardly projecting parts inserted between the water-tubes 1, and alternate rows of bricks have a hole in the projecting part to take an iron rod 3 having at each end a bolt 4. Bricks 5 are loosely inserted in the spaces between the projections and an elastic caulking plate 6 is arranged to cover a number of bricks to form a block or panel. A metal or ferro-concrete plate 7 is placed over the elastic plate 6, which may be of felt, and the whole joined together by nuts on the bolts 4. The horizontal joints between the bricks are broken as shown in Fig. 3, and alternate rows of bricks are held in position by these break-joints alone. The bricks 2 do not touch each other and the bricks 5 only approximately fill the spaces between the rearward extensions so that there is no expansion of the wall as a whole. When the invention is applied to a pulverulent-fuel boiler furnace the walls may be jacketted to form a chamber from which air may be taken to the furnace.
