Title: Improvements in Mechanical Stokers.
IPC: F23K3/08
Filed: 1917-03-09
Abstract: 112,695. Goodrich, W. F., Hamlyn, W. R., and Goodrich & Hamlyn. March 9, 1917. Mechanical stoking.-In connexion with a travelling grate, an attachment is provided for grading the fuel and depositing the larger pieces on the grate at a point or points nearer the front, the smaller and dusty particles being fed as an upper layer at a point farther back. The apparatus comprises a riddle or screen and a toothed roller at the front thereof. The larger pieces of fuel pass from the screen over the roller and fall on the front of the grate. A guide-plate f is provided for the fine fuel falling through the screen. In Fig. 1, the screen h is shown pivoted, and the toothed roller c is arranged to impart an intermittent rising and falling motion to it. A stop g is provided to relieve the teeth of the roller from the shock of the descending screen, and this may be mounted on springs. In Fig. 3, the screen m is shown fixed, and the roller; n has long and. short teeth, the long ones passing between the bars of the screen and agitating the fuel thereon. The roller may be divided transversely into sections which are spaced apart a greater distance than the width of the spaces between the bars of the screen,. so that pieces of fuel of an intermediate size will fall between the sections. The roller may be operated by ratchet gear, or otherwise. The grading attachment may be placed beneath the storage hopper, in which case provision is made at the feed hopper for preventing remixture.

Title: Improvements in Circuits Employing Artificial Commutation of a Controllable Rectifier Device
Inventor: KING KENNETH GORDON
IPC: H02M7/515
Filed: 1967-01-24
Abstract: 1,174,118. Inverting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 21 Dec., 1967 [24 Jan., 1967], No. 3529/67. Heading H2F. [Also in Division H3] An inverter provided with a commutating capacitor Cl, Fig. 1, for turning off the rectifiers Tr1-Tr4 and including an inductance L1 in the D.C. supply line, is provided with an auxiliary capacitor C2 for absorbing inductive current in the inductance when the rectifiers are turned off. The capacitor may be connected in series with a diode MR5, and the next pair of rectifiers (Tr1 and Tr4 or Tr2 and Tr3) should be fired at the time when the inductive current has returned to normal; if this is not done the rectifier Tr6 or Tr7 should be fired at this instant to provide a continuing re-circulating path for the current in L1 or L2. This instant is the time when the voltage time integral across the inductance is zero, and may be determined by a saturable reactance (L3, Fig. 4 or Fig. 5, not shown) in parallel with the inductance. As shown in Fig. 1, a second auxiliary capacitor C3 and diode MR6 may be associated with a second inductance L2, but this is not necessary if the two inductances are inductively coupled. In a modification, Fig. 2 (not shown), the junction of C2 and MR5 is connected to the junction of MR1 and MR3, and Tr6 is connected directly across L1. If the D.C. supply to the inverter is derived from a rectified A.C. source, the charge across C2 may be restored to the A.C. source via an auxiliary inverter, Fig. 6 (not shown). Alternatively, Fig. 8, the charge on C2 may be restored to the inverter by firing the rectifier Tr10. Fig. 8 illustrates a different type of inverter, but the same arrangement can be applied to the system of Fig. 1 or to a three-phase bridge (Fig. 12, not shown). To avoid the possibility of Tr10 remaining conductive all the time it may be preferable to connect MR10 to a tapping on L1 (Fig. 9-12, not shown). Rectifiers Tr1 ... Tr12 may be triggered by a time delay device following the triggering of Tr5 or by sensing the voltage across C1, L1 or L2.

The servo unit 3 is mounted on a housing 9 and has an input shaft 1 carrying a steering wheel 2, and a vertical output shaft 4. A shaft 5 is connected to the front axle 6, the shaft 5 being coaxial with the shaft 4 and separated therefrom by a thrust bearing 8. The shaft 5 carries a planetary speed reducer 14 consisting of sun gear 20 fixed to the shaft 5, planet pinions 18 mounted on a carrier 19 and toothed annulus 15 mounted in a hub 16. The hub 16 carries an external gear 17. The steering linkage 13 is operated by a pitman arm 12 which is fixed to a gear 11 which is rotatably mounted on the output shaft 4. The shift coupling 21 consists of an axially movable inner sleeve 22 keyed to the output shaft 4 at 28 and carrying gear rims 25, 26 and an axially movable outer sleeve 23 keyed to the housing 9 at 29 and carrying gear rims 24, 27. The sleeves 22, 23 are moved axially by a rod 32 and lever 33. In the position shown in Fig. 1 the output shaft 4 is connected to the speed reducer 14 on shaft 5 by gears 17, 26 and the pitman arm 12 is locked by gear 24 on the outer sleeve 23 engaging gear 11. When the shift coupling is raised (not shown) the output shaft 4 is connected to the pitman arm by gears 25, 11 and the axle 6 is locked by gear 27 on the outer sleeve 23 engaging gear 17. Thus, with the axle 6 locked, the tractor can be steered in a conventional manner. When it is desired to turn the tractor around, the shift coupling 21 is operated to unlock the axle 6 and lock the pitman arm 12 and the steering wheel 2 is turned until the wheels 7 lie in the curved track of the outer driving wheel 34 as shown in Fig. 2. After the turn the axle 6 is returned to its transverse position and the shift coupling 21 is operated to lock the axle 6 and unlock pitman arm 12.
