Filed: 1957-02-19
Abstract: 802,776. Gyroscopic apparatus. PROTOCORP, Inc. Feb. 19, 1957, No. 5638/57. Class 97(3) Gyroscopic apparatus includes a gyroscopic element floating substantially at neutral bouyancy in a compressed gas in a pressure container. As shown in Fig. 1, a sphere 12 is mounted in bearings 14 in a ring 16, which itself is mounted in bearings 17 in a ring 18, which in turn is mounted in bearings 19 in a ring 20 mounted on a base 10. The sphere, which may have e.g. an inside diameter of 2.2 cm. and a thickness of 0.2 cm, is filled, through a closure 22, with a gas such as nitrogen at a pressure of 13,500 p.s.i. An inner sphere 25, forming the gyro rotor, may be of magnesium-aluminium alloy of about 2 cm. inside diameter and 0.07 cm. thick, is filled through a closure 26 with a lighter gas, e.g. hydrogen, also at a pressure of 13,500 p.s.i. Alternatively, the inner sphere may be solid, of light material such as lithium. with flattened pole portions, and the flotation gas is of high molecular weight and may be xenon or krypton. To drive the inner sphere, the outer sphere may be driven by a motor consisting of a stator 40 and a rotor 42, this rotation being imparted to the inner sphere 25 by viscous drag. Friction locks, disengaged by centrifugal force at a desired operating speed, may also be used, and the outer sphere may be driven by an air turbine. The inner sphere may be centred with respect to the outer sphere by means of eddy currents, magnets or by electrostatic means, e.g. eddy currents may be induced by three windings at right angles outside the sphere 25. Other centring means are also mentioned. Displacement between the inner and outer spheres may be indicated by currents set up by magnets on the inner sphere in coils mounted on the outer sphere. The signal generated may be used to apply correcting torques to the inner sphere or to align the axis of the outer sphere with that of the inner sphere.

Patent GB-142601-A (GB)
Title: Improvements in and relating to apparatus for controlling and stopping vehicles
IPC: B60T13/40
Filed: 1919-03-13
Abstract: 142,601. British Thomson-Houston Co., (General Electric Co.). March 13, 1919. Sand, distributing on wheel tracks. - In a fluid-pressure braking and controlling system for railway vehicles arranged for service, and emergency applications, means are provided for actuating the sanding-mechanism for the rails for a predetermined time at each emergency application of the brakes, the mechanism for opening the doors being actuated at the end of the sanding operation. Fluid pressure is suppiled from a reservoir 2, Fig. 1, to the emergency valve 4 through a pipe 3, the pressure fluid having access to both sides of a piston 18 through ports 45, 21, 46, 49. When a straight application of the brakes is made by turning the driver's valve 8 to a service position, pressure fluid is supplied through the pipes 7, 9 to the brake cylinder 6 without affecting the piston 18. On the valve 8 being moved to emergency position, pressure fluid flows to the brake cylinder more rapidly than it can be supplied to the chamber 17 through the restricted port 21. This causes the greater pressure above the piston to move it downwards against the spring 28, and the slide valve 20 is lowered into the position in which pressure is supplied from the cylinder to the brake-pipe 5 through the port 40 and passages 22, 24. The passage 27 is also uncovered, so that pressure fluid passes to the timing-valve 12 shown in Fig. 2. The piston 32 is thereby lifted against a spring 37, and the slide valve 33 is moved to uncover the passage 44 and allow pressure fluid to pass through the pipe 15 to the sanding-mechanism 16. After a certain period, sufficient pressure fluid has passed through the passage 39 to enable the slide valve 33 to be moved back to its normal position, cutting out the sanding-mechanism. This movement of the slide valve uncovers the pipe 13, so that pressure is supplied to the cylinder of the door-opening mechanism. When the brakes are released after an emergency operation by the movement of the driver's valve to release position, the emergency line 7 is re-charged to the main-reservoir pressure, and the valve 4 is returned to its normal position. The timing-valve 12 is thereby connected to exhaust through the pipes 10, 11. The arrangement acts in a similar manner by an automatic emergency operation of the brakes, as, for example, when the train breaks in two.

Feb. 28, 1935, No. 6364. [Class 125 (ii)] In applying screw stoppers to bottles, the stoppers are fed on to an inclined band conveyer e<1>, Fig. 3, whereby they are caused to pass over the delivery end in the normal. vertical position and fall thus into a shoot f<1> which guides them in the correct position to the stoppering head g. The conveyer e<1> is dis. posed at an angle of from six to ten degrees to the horizontal which causes the majority of the stoppers to assume the position shown in Fig. 3. Some may lie upside down thereon, but in every case the stoppers are delivered to the shoot f<1> in the normal vertical position. The stoppers are fed from a hopper a to a selector wheel d having pockets e and are discharged from thence on to the band e<1>. The stoppering head g is rotated by an adjustable friction wheel h engaging a friction disc i on the shaft k, Fig. 1, the wheel h comprising segments l which are expanded against a circumferential band o by the action of a cone m slidable on the shaft n. The bottles on a platform p are raised to and lowered from the stoppering position by an eccentric r.
