Abstract: 205,759. Geiser, C. J. Feb. 6, 1923. Amusement apparatus. - An amusement device comprises an animal figure, such as a horse, provided with a steering-device and electric-motor propelling means, the steering and propelling means being operated by reins leading to the mouth of the figure. As shown, the figure is mounted on a truck 1 having wheels 4 driven by a motor 6 through gearing, a supporting-wheel 3, and a supporting-wheel 2, which is connected by a chain e to a vertical shaft c in the supporting-standard 27. The reins 20 are secured to a "bit" 21 on a spindle 21<x> in the horse's mouth, the lower end of the spindle being provided with an arm a to the ends of which are levers b operating the shaft c, thus providing means for steering the truck 1. The reins also serve to put a spring plate 15 into contact with a plunger 13<x>, completing the circuit for the motor 6, to which current is supplied from overhead netting 11 and floor 10 by a standard 17 and trailer 12. A crank 29 driven by a chain 32 from the axle 5 of the wheels 4 is connected to the hind legs of the horse to produce a rocking motion.

Title: Improvements in or relating to combined power generating and gas vaporizing units
IPC: F02C7/143
Filed: 1968-01-24
Abstract: 1,213,725. Gas turbine plant. TEXAS EASTERN TRANSMISSION CORP. Jan. 24, 1968 [May 9, 1967], No.3669/68. Heading F1G. Also in Division F4] The invention relates to a method of vaporizing liquefied natural gas by utilizing the hot exhaust gases of a gas turbine engine, the engine being utilized to generate power. In Fig. 1 a gas turbine engine 10 drives an electric generator 11 and the exhaust gases from the engine discharge through a heat exchanger 12 wherein liquefied natural gas at temperature of -258‹ F. supplied through line 14 is vaporized and discharges at a temerature of 60‹ F. to a point of use. The inlet air to the engine is at a temperature of 80‹ F. and the turbine exhaust gas is at 925‹ F. In Fig. 2 the inlet air to the gas turbine engine is cooled to 40‹ F. by passing through a pre-cooler 15 through which vaporized natural gas at 18‹ F. discharged from the vaporizer 12 is passed. Cooling of the intake air results in increased power from the gas turbine engine and so from the generator 11. In Fig. 3 the ambient air flowing through the pre-cooler 15a is cooled by passing liquefied natural gas at -258‹ F. direct from the storage container therethrough. The temperature of the inlet air is reduced to 0‹ F. and that of the liquefied natural gas is increased to -168‹ F. The liquefied gas is then passed through the vaporizer 12 where it is heated by turbine exhaust gases, the natural gas being thereby vaporized and discharging to a point of use at a temperature of 60‹ F. This additional cooling of the inlet air further increases the power of the gas turbine engine.

A pilot wire circuit arrangement comprises pilot wires A', A<SP>2</SP>, a voltage source B, b at each end, two opposed rectifiers C, c one at each end in series with the pilot circuit, a resistance D, d shunted across each rectifier C, c, a shunt rectifier E, e at each end connected across the pilot wires on the pilot wire side of the associated series rectifier and in opposition to the series rectifier, and relays F, f or other current responsive means connected in series with each shunt rectifier. The arrangement may be applied to a Merz-Price protective system in which case the sources B, b are the secondary windings of current or summation transformers associated with each end of a protected section and so connected that when the currents at each end are in phase, i.e. under external fault conditions, current circulates in the pilot circuit through rectifier C and resistance d on one half cycle and through rectifier c and resistance D on the other half cycle. Neither relay is energized as on one half cycle the shunt rectifier E or e opposes flow of current through the associated relay and on the other half cycle no potential exists across the relay, the shunt resistances D, d each having a resistance not less than half that of the pilot wires. When the currents at each end are 180‹ out of phase, i.e. under internal fault conditions, no current circulates in the pilot wires and the relays are energized on alternate half cycles through the resistances D, d. In the event of an internal fault in the protected section fed from one end only, the relay at the feeding end is energized through the shunt resistor on alternate half cycles. In the polyphase arrangement of Fig. 7, the d.c. control winding O<SP>1</SP>, o' of a transductor is connected in series with .each shunt rectifier E, e and the associated relay F, f, is connected in series with the a.c. operating winding, a further secondary winding B', b<SP>2</SP> and a bridge rectifier P, p. Additional rectifiers S, s connected as shown may be provided to reduce the risk of incorrect operation in the event of the pilot wires being crossed.

The application of excessive voltage to the pilot circuit is prevented by non-linear resistors L, l, by themselves or in conjunction with transformer-coupled linear resistors N.
