Sanders, T.H. (Paper No. 271)
Locomotive suspension, and its influence on derailments. 133-55. Disc: 155-63;
205-15; 859-65.
Four un-nnamed accidents, but clearly including those at Sevenoaks
(Maunsell River class) and Buchlyvie (Gresley N2 class). Suggested
that had River class been fitted with the Zara-type of leading pony truck
that the Sevenoaks accident would not have occurred. On page
863 it is noted that equalising gear was invented by R.&W. Hawthorn
in 1851, but may been invented earlier in Europe, but not in America.

Sanford, D.W. (Paper No. 273)
Development of the piston valve to improve steam distribution. 217-49. Disc.:
304-10.
J. Clayton (237) noted that the Smith type used on the Midland compounds
were not very steam tight. E.C. Poultney (238) supported Clayton's assertion
and considered that piston valves were not suitable for low pressure
cylinders.

Andrews, H. Ivan (Paper No. 275)
The possibility of condensing on locomotives. 336-78. Disc.: 537-9.
The criteria were: light weight, small size, low initial cost, low
maintenance, reliability, constant performance under varying conditions,
low power demand for draught, adequate capacity/reserve capacity for short
periods. The Cole evaporation rate
should form the basis for the last-named.

Chambers, H. (Paper No. 277).
Improvements in water pick-up gear for locomotives. 450-64. Disc. : 464-72;
787-93 + 3 folding plates. 7 illus., 9 diagrs.
Improvements in the design to save water: invented by H. Chambers.
Henry Fowler (464-5: presumably Sir Henry's son) commented upon the MR design;
J. Clayton (465) noted the problem of water wastage; H. Holcroft (465-7)
commented on th problems of getting rid of excess air from the tanks on tank
engines and not that a new design was fitted to The Great Bear. A.M.
Bell (467-8) noted that the installation of water troughs was important for
operating the Norfolk Coast Express..

Holmes, V.W. (Paper No. 278)
A new infinitely variable poppet valve gear. 481-90. Disc.: 490-524.
One of the very few lady members of the Institution: she asserted
that the use of poppet valves prevents wire drawing at admission and back
pressure and exhaust. To obtain the full advantage from poppet valves, the
gear should fulfil the following criteria: (1) the cut-off should be infinitely
variable, not limited to a series of steps; (2) the lead should vary slightly,
being greatest with early cut-offs, and least in full gear, in order to
facilitate starting; (3) again to facilitate starting, the cut-off should
be high in full gear; (4) the valves should open and close rapidly, and should
give a good area of opening even with early cut-offs; (5) the exhaust valve
timing should not be fixed, but should vary slightly with the cut-off, both
releases and compression being delayed with late cut-offs; (6) the cam box
should be as compact as possible, with the cam shaft not too high above the
cylinder centre line; (7) the cam box should be a standard unit, capable
of rapid removal and replacement by a spare box. Left and right-hand boxes
should be interchangeable, and left and right-hand cylinders also should
be identical; (8) the valves should be carried in cages, which should be
capable of rapid removal, and (9) the control gear should be as simle as
possible and minimize effort. The discussion included comment from Holcroft,
Gray, Twinberrow, Baeumont and Maitland..

Agnew, W.A.
Presidential Address: railway electrification. 636-56. Disc.: 1932,
22, 83-8.
P. Liddell (22: 83-5) noted the difficulties involved in
electrifying from Newcastle to King's Cross and considered that the lines
to Sunderland and South Shields should be electrified. A.H.T. Head (87)
considered that the cost of repairs to electric locomotives would be
high.
