Abstract: 454,755. Measuring current. AKT.- GES. BROWN, BOVERI, & CIE, Baden, Switzerland. Feb. 4, 1936, No. 3324. Convention date, Feb. 4, 1935. [Class 37] [See also Group XXXVII] A protective relay in which the force exerted on the movable relay member varies continuously with its excit. ing current and is utilized during operation to indicate visibly the momentary value of the factor to be kept under observation by, for example, a pointer moving over a scale is arranged to have the movable relay member coupled below the limit of response of the relay with the indicating appliance and above this limit with the releasing device of the relay. As shown in the Figure, the operating member consists of a Ferraris drum rotor c in the air gap of a core a with winding b and shading rings e on the pole faces. The drum is mounted on a shaft d which has a pointed lower end supported in a conical fixed bearing g and a movable intermediate bearing h. Normally, a pinion i on the shaft d engages a pinion o on a shaft n carrying a pointer p moving over a scale r, the shaft n being rotatable against a spiral spring q. Thus, with normal loading of the controlled circuit an indication of the value of the load value is given, but when abnormal conditions occur an electromagnet z attracts its armature v moving the bearing h to the right against the spring f and so disengaging the pinion i from the pinion o and moving it into engagement with the pinion t. The shaft s on which the pinion t is secured is then rotated causing the closing of contacts, the tripping of a circuit-breaker or any other relay action.

Title: Improvements in and relating to alternating current commutator machines
IPC: H02K27/04
Filed: 1922-02-13
Abstract: 197,722. Creedy, F. Feb. 13, 1922. Alternating-current commutator machines.- In an alternating-current commutator machine in which a phase-compensating voltage, derived from an auxiliary stator winding acting as secondary to the main stator winding, is impressed on the commutator, the auxiliary winding is distributed so that the turns in one pair of slots are connected in series with those in other pairs of slots symmetrically placed with respect to other poles before being connected in series with the conductors in a second pair of slots adjacent to the first pair. Taps may be provided on the auxiliary winding to enable the motor to run on different voltages. The auxiliary winding T<1>-T<5>, Fig. 1, is in series with the main winding S<1>-S<2> across the line and is tapped at T<2>, T<3>, T<4> so that when the contact A is moved the machine may be made suitable for different line voltages. The compensating voltage applied to the brushes X<1>, X<2> may also be varied by means of the contact A<1>. The windings S<1>, S<2>, T<1>, T<5> may be independent, the contact A being connected to the point S<2>, for high voltage supplies or, as shown in Fig. 2, the brush X<2> may be directly connected to the line, thereby giving a series connection between the rotor and stator coils. The contact A' is moved so that at full speed a greater number of stator turns, is included than before the brush X<2> is connected to the auxiliary winding, thereby giving a powerful starting flux and torque. A developed auxiliary stator winding for a 4-pole 28-slot single phase machine is shown in Fig. 3. Slots 4, 11, 18 and 25 are blank and each pole is defined by three concentric coils e.g. 1, 2, 3 and 5, 6, 7. The coil in slots 1, 7 instead of being immediately in series with 2, 6 is connected in series with 15, and 21, 28 and 22 and 14 and 8, symmetrically placed with respect to the other poles, before connection to 2, 6. The taps T<2> - - T<5> may thus be brought out in approximately equal steps from an uniformly distributed winding. Starting from terminal T<6> the winding makes one turn around each pole before tap T<5> ; then one around each pole and an extra one before tap T<4> and so on. The application to a two-phase winding is also described in the Specification.

Title: Improvements in or relating to aerostats
IPC: B64B1/64
Filed: 1927-02-16
Abstract: 290,716. Scott, G. H., and Rope, F. M. Feb. 16, 1927. Aerostats.-An automatic gas valve for an aerostat gas bag is constructed and arranged so as to be approximately balanced as regards directly-transmitted gas pressure from the gas bag, but so as to have a small resultant positive tendency to close; improved control means are also provided for opening the gas valve in a decisive manner and to the full extent under a predetermined maximum pressure in the gas bag. The automatic valve B is fitted to the gas bag A, preferably above the highest level to which the bottom of the gas bag can rise, and comprises an outer stiff diaphragm B having a conical central portion and a cylindrical peripheral portion, which carries a valve face F in the form of an annular plate adapted to engage a seating E formed on a cylindrical member fixed in the gas bag aperture. The valve B slides on a tubular axial guide M supported by a spider M<1> fixed in the gas bag aperture. A stiff diaphragm G of conical form is fixed to the hub of the spider M<1>, and is connected to the movable valve face F by a collapsable bellows H. The pressure from the gas bag passes through the central opening Y of the valve into a chamber F bounded on the outside by the bellows, and holds the valve face on its seating E. A chamber J bounded by the diaphragm B, the bellows H, and the diaphragm G communicates through the tubular guide M and a connection C<1> with the gas bag, preferably through a siphon pipe, which is connected to the gas bag near the valve and has its bend at or slightly below the bottom of the gas bag when full, so that when the gas pressure reaches its maximum the pressure on the diaphragm B rapidly lifts the valve face F from the seating E to the full extent of the movement of the valve along its guide M. A leak is provided to bring the pressure back to atmospheric, and a spring K then returns the valve to its seating. Alternatively, a relay valve set to operate at a predetermined pressure in the gas bag may admit gas pressure to the operating- chamber J. An auxiliary hand-operated valve may be provided to operate the automatic valve for manoeuvring and other purposes. Further detail modifications are described.
