Title: Improvements in and connected with power transmission gearing for the running axles of vehicles
IPC: B61D43/00
Filed: 1927-12-21
Abstract: 307,990. Stone & Co., Ltd., J., and Hatcher, E. C. Dec. 21, 1927. Movements of vehicles, utilizing.-In toothed, chain, or similar positive gearing for transmitting power from the running axles of a railway or like vehicle to a dynamo, compressor, or other piece of apparatus, undue strain on the gearing when the axle is strongly braked is prevented by the provision of a centrifugal clutch associated with the shaft of the dynamo or other machine so that the latter may be allowed to over-run the axle when the speed of the latter falls rapidly. The invention is described in connection with a toothed gearing in which the gearwheel immediately associated with the axle is not directly conectned thereto but is constituted as a hollow cylinder surrounding but spaced from the axle and connected to the latter by a flexible or universal coupling so that axial or other movements of the axle do not affect the correct meshing of the gears. In the construction shown in Figs. 1 and 3 the gear-wheel f is adapted to drive a quick pitch worm e and is combined with a sleeve f<1> spaced from the axle a and provided with forked extensions m serving to couple the sleeve to the axle. This coupling, Fig. 2, comprises two unequal half-rings n, n<1> embracing the axle a, the larger ring n<1> being provided with pins p rotatable in sockets r in a gimbal-ring q having pins s capable of axial and rotary movements in the forks m. The driven member e is rotatably mounted on an extension d<2> of the dynamo shaft d and is provided with centrifugally-acting shoes co-operating with the internal surface of a brake drum k fixed to the shaft extension d<2>. Modifications are described in which the gear-wheel f meshes with an idle spur-wheel driving a second spur-wheel associated with the dynamo &c. shaft, and in which the heads of the pivot pins p, s either slide in slots in the members they engage or have spherical heads movable in tubular portions thereof.

Title: Improvements in or relating to rotary regenerative heat exchange apparatus
IPC: F28D19/04
Filed: 1955-12-05
Abstract: In an arrangement for determining the extent of fluid leakage from a high pressure fluid stream to a separate low-pressure fluid stream a predetermined quantity of radio-active material is introduced into an upstream zone of the high pressure stream and the extent of such leakage determined by the difference between <PICT:0801148/III/1> the intensity of radio-activity measured at the upstream zone of the high pressure stream and at a point downstream of the low pressure stream. When a plurality of possible leakage paths of different length exist the extent of leakage over each path may be determined from the intensities of, and the different intervals between the occurrences of "bursts" of radio-activity at the downstream point produced by the introduction of a single "burst" at the upstream point.  The invention is described in connection with a rotary regenerative heat exchanger employing heat transfer material in the form of metallic plates 14 which rotate about a vertical axis and convey heat from a hot gas stream (consisting of the gaseous products of combustion in a furnace) supplied at inlet duct 15 and released at outlet duct 25 to a cold air stream supplied under pressure (e.g. by means of a fan) at inlet duct 27 and, after absorbing heat from the plates 14, supplied to the furnace as an air blast via outlet duct 17.  In accordance with the invention a quantity of radio-active material in the form of a gas is introduced into the air stream at duct 27 and by comparing the intensity of the activity as measured by a detector 6 with the intensities measured by detectors 7, 8 and 9 and also by intercomparision of the readings of the latter detectors the nature and extent of the various forms of leakage in the system may be determined.  Considering leakage from the air stream to the gas stream which can occur in the rotor of the heat exchanger over paths of different length, viz: (a) leakage past the radial seals 18 over paths 1 and 2; (b) leakage past the circumferential seals 22 over paths 3a, 3b, 4a and 4b; and (c) leakage over path 5 due to fluid extrained in the rotor and carried over to the gas stream, the extent of such leakage and the particular path over which it occurs may be determined by measuring the interval between and the intensity of activity at detector 6 and the different surges produced at detector 7, these latter occurring, in order, due to leakage over the paths of increasing lengths, viz. 5, 2, 3a, 3b, 4a and 4b.  The total leakage determined in this manner should be equal to the leakage from the air stream as determined by the different intensities measured by detectors 6 and 8 less any loss of fluid from the system (e.g. in the furnace) which is determined by the difference between the intensities measured by detectors 8 and 9.
