Title: Improvements in Apparatus for Compounding Synchronous Alternating Current Machines.
Filed: 1905-05-10
Granted: 1906-05-10
Abstract: 9837. Bruce, Peebles, & Co. and La Cour, J. L. May 10. Dynamos, regulating; motors, controlling.-In compounding synchronous alternating-current machines, the field magnets are excited by continuous current from a rotary converter, with rotating field, which is fed with alternating current from the secondaries of transformers in series and shunt with the armature windings of the synchronous machine, the converter and synchronous machine being mechanically connected. As shown in Fig. 1, the primaries ps of the transformers HT1, HT2, HT3 are connected in series with the armature windings I, II, III of the three-phase generator G. In parallel with the primary windings are placed resistances R1, R2, R3, which serve to regulate the current in the series transformers. Across the bus-bars are connected the primaries pn of shunt transformers NT NT2, NT3. By means of brushes and sliprings, the secondaries of the two sets of transformers, which are in series, are connected to the windings A1, A2, A3 of the converter. To prevent sparking at the commutator brushes B, the rotor of the converter is preferably wound in the manner described in Specification No. 28,416, A.D. 1904, and the stator T‹ provided with armortisseur coils Am in the commutating-zone The rectified current is taken from the brushes B to the field windings GF of the generator G. The shunt transformers may be replaced by additional windings on the armature of the generator or by using in their place part of the main windings. In the modification shown in Fig. 1<a>, a single-coil transformer replaces the series transformer, while the shunt transformer is dispensed with. The stator To, which preferably has no winding upon it excepting the armortisseur coils Am, may be provided with a two-phase winding, one phase of which receives current from brushes displaced ninety degrees from the brushes B. In starting synchronous motors and phase regulators, the field-magnet winding is short-circuited until the machine has reached nearly the synchronous speed, when the winding is opened and connected across the brushes B.

Title: Improvements in Pressure Reducing Valves.
Inventor: HUBNER JOSEF
Filed: 1906-02-08
Granted: 1906-11-01
Abstract: 3134. Hubner, J., and Mayer, I. Feb. 8. Reducing-valves.-In a reducing-valve, the action of the loaded diaphragm or piston is assisted by a suction effect produced by a nozzle e, Fig. 1, placed in the low-pressure passage' and communicating with the underside of the diaphragm b by means of a tube d. The effect of the suction device is that, as the consumption of steam increases and the load on the valve owing to its opening movement becomes less, the suction effect will increase and draw down the diaphragm, thus opening the valve proportionately to any demand at the required low pressure. In a modification, the passage d and nozzle e are formed in the spindle a. In this case, a spring-loaded piston is used in place of the diaphragm. In a further modification, Fig. 3, the steam-pressed piston b is connected to an auxiliary valve v in a main valve m. High-pressure steam passes through the auxiliary valve into a chamber h, thus allowing the main valve to open, and thence through a suction nozzle e connected with the underside of the piston b.
