As shown in Fig. 1 container 1 of liquid 2 houses drum 3 the curved surface of which is perforated.  Drum 3 may be mounted on a fixed axle (not shown) and caused to rotate by a motor (not shown) about this axle. Drum 3 contains a stationary partition 5 (integral with the fixed axle) which may have sealing elements 4 at its outer ends abutting the inner surface of drum 3.  Partition 5 divides drum 3 into two segmental chambers the lower one being connected to a source of suction e.g. pump 14, while the upper one may contain channels 11, 12 the former due to suction causing fibrous material to be drawn on to the curved surface of drum 3 and the latter due to blowing causing the fibrous material to be detached from the curved surface of drum 3 after treatment.  The fibrous material may be squeezed during its passage through liquid 2 between the curved surface of drum 3 and roller 13.  In a modification (not shown) the fibrous material may be detached from the curved surface of the perforated drum by means of a stripping roller.  Figs. 7 and 8 show a modification in which three perforated drums 17, 18 and 19 are mounted in side by side relationship and are separated by transfer rolls 20.  Baffle plate 27 serves to direct the liquid under the pressure of pump 14 for each chamber 7 back into the container beneath the suction chamber.  In an embodiment (not shown) five perforated drums are arranged in side by side relationship such that the fibrous material passes in a sinuous path therebetween, the suction chambers being arranged alternately at the bottom or top of each drum.

Title: Improvements in or relating to thermo-electric pyrometers
IPC: G01K7/02
Filed: 1927-12-23
Abstract: 297,261. Lloyd, G. E., and Electroflo Meters Co., Ltd. Dec. 23,1927. Pyrometers. - I n order to give a warning of the breakage of a thermocouple pyrometer, the thermocouple and its deflecting instrument are arranged in a normally balanced Wheatstone bridge system supplied from an independent source of E.M.F. in such a way that the bridge becomes unbalanced when the thermocouple breaks, and an increase in the reading of the deflecting instrument results. The thermocouple 8 in series with an adjustable resistance 7 and fixed resistance 6 is arranged as one arm of the bridge of which the other arms comprise fixed high resistances 3, 4, 5. The galvanometer &c. 1 is arranged in series with an adjustable resistance 2 across the bridge to which current is supplied by a battery &c. 9 in series with an adjustable resistance 10. The bridge is initially balanced by adjusting the resistance 7 until no change in the deflection of the galvanometer occurs when the circuit of the battery 9 is made or broken. The normal pyrometer circuit then comprises the thermocouple 8, galvanometer 1 and resistances 2, 5, 6, 7. Should the thermocouple break, the bridge is thrown out of balance and the resulting increase in the deflection of the galvanometer gives warning of the breakage. The invention is particularly applicable to systems in which the galvanometer controls, through a relay &c., the supply of heating medium to an enclosure. In such a system the increase of the deflection consequent upon breakage of the thermocouple results in the supply of heating medium being cut off.
