"This booklet offers analytical and experimental tools and achievements in designing mechanical and mechatronic driveline platforms. Examples contain a number of strength dividing devices, together with symmetric and non-symmetric types, in addition to open and lockable differentials, numerous restricted slip differentials, no spins, and viscous clutches.

In onc form of torpedo gear apparently de igned for the Type C (and evidently that which the line-drawings how) the projectile was to have a single-point uspension from a shackle on a longitudinal beam, and was to be steadied against waying by fittings that eventually became known as 'crutches'. Release-effected from the pilot's seat-was to be mechanical. Having introduced these notes on the Sopwith Type C with reference to early Italian experiments in torpedo-dropping it seem fitting to append the following: In 1913 it was reported-apparently on good authority-that three 'Sopwith type hydro aeroplanes' had been ordered by Italy: and though these were termed, in one context, as 'torpedo air-craft' it must be recognised that this particular expression was in fairly common international currency at that period to connote heavier-than-air machines of the 'fighting', 'scouting' or 'bomb-dropping' pcrsuasion, as distinct from lighter-than-air craft.
Clearly, these scaplanes wcrc underpowered, e pecially when carrying bombs or wireles equipmcnt in hot climates. More, indeed. is known concerning the operational performance of these aircraft than can be stated with confidence respecting their technical characteristics. Folder sufficient problem. the airframe came 'unstuck' when not required to do so, the trouble here being the type of glue applied in ngland. Ithough no guns were carried, bombs most certainly were-seemingly on the noat cross-bracing struts; and in this regard one may now enlarge on the wellknown instance of one of the 'anti-Konigsberg' Sopwith Folders refusing, day after day, to leave thc water with a full complement of crew and petrol-plus two 50 Ib and four 161b bombs.
In the strong sunshine and at the height the evolution was carried out it was difficult to follow every detail of movement, but to most It seemed that the machine, after turning vertically upwards, fell to one side, and then, turning over, completed the loop prior to planing down. Mr. Tom Sopwith ran out to 0reet M r. " Hi idea of his movements, however, coincided with the above opinion, 0, apparently quite satisfied a to what he had to do the next time, he immediately restarted, and at his econd attempt made three very good loops at a height of about 3,000 feet.
