[Also in Group XXVIII] A duet 1, Fig. 3, for hot gases, e.g. a combustion duct in a ram-jet engine, is shielded by an inner wall 4 composed of rectangular sheet metal elements 5 secured in overlapping relation to the wall 1 in such manner that no stress due to thermal expansion is transmitted to the wall 1. Cooling fluid flowing through the space 15 between the walls 1, 4, escapes through slits 10 between the edges of the elements to cool the inner surface of the wall 4. The side edge 6, Figs. 1 and 2, of each element is dished at 6a to slidably receive the adjacent flat edge 7 of the adjacent element and is formed into a trough-shaped member 15 which is spot welded at 16 to stringers 2 on the wall 1 and at 14 to the adjacent element. The flexibility of the trough walls 11, 12 permits sliding movement of the edge of one element relatively to the adjacent element so that sideways thermal expansion of the elements is permitted without transmitting stress to the wall 1. The upstream end of each element is dished at 8a to form the slit 10 and the downstream end is spot welded to a stringer 2, the trough portion 15 being dished at 18 to form a guide for the upper end of the adjacent element which is free to slide to take up longitudin al expansion.

In an automatic voltage control system for a motor-generator, a generator field winding, the excitation of which is controlled in response to output voltage, is opposed by a, winding excited in response to output Current so that a predetermined output voltage is maintained under pulsating load conditions. In the rotary transformer shown, a motor armature winding 6, supplied through a commutator 8 from a D.C. source 22, co-operates with field poles 10, 11 carrying shunt windings 13, 14 and cumulative series windings 15, 16. Part of a generator armature winding 7, supplying lines 32, 33 through a commutator 9, also co-operates with field poles 10, 11, and part co-operates with field poles 17, 18. Field pole 18 carries a main winding 20 connected in series with windings 13, 14 and field pole 17 carries an opposing winding 19, the excitation of which is controlled by a carbon pile regulator 27, a winding 28 of which is responsive to the generator voltage. The arrangement serves to maintain generator voltage constant, but, in order to improve stability of regulation upon sudden changes of load, a winding 21, carrying output current, assists generator field winding 20, and a winding 29 carrying the current in generator field winding 19 assists regulator winding 28.
