Abstract: A driverless carriage with automatic steering rendering the carriage capable of travelling in a straight line as well as performing a rotation about a vertical axis. To improve the precision of the turning movement, the carriage monitors during said movement the position, with reference to the surface on which the carriage moves, of the axis of rotation of the carriage. At least one measuring wheel engages the surface to detect a deviation of said vertical axis from a stationary position to produce a correction signal used for adjusting the steering of the carriage so as to eliminate the deviation of said vertical axis from the proper position.

Abstract: A tractor has an engine, a torque converter, a lifting device for attachment to an implement such as a plow, the torque converter being controlled automatically whereby if an engine-driven ground wheel starts slipping, the torque converter reduces the tractor's speed. Engine speed and the implement's depth of penetration are also automatically controlled in dependence on the retarding force caused by the implement. In another embodiment, a power take-off shaft is automatically disengaged if the retarding force becomes excessive.

Abstract: A diaphragm for electro-acoustic transducer which, as a component member, utilizes a layer of ceramics material, by which the E/.rho. ratio of the diaphragm can be increased, leading to an elevated resonance frequency of the diaphragm, whereby the limit frequency for reproducting of high-pitch sound can be shifted high, thus making it possible to widen the range of piston motion of the diaphragm, and to thereby improve its frequency characteristic. Also, a diaphragm utilizing a composite board formed by lamination of a layer of ceramics material and a layer of light-weight metal eliminates the fragility of diaphragm would entail when the diaphragm utilizes a single layer of a ceramics material alone, and thus the handling of the diaphragm is facilitated.

Abstract: A bearing chamber is provided with drains on both sides of the bearing thus preventing oil surges spilling oil over the chamber seals. The bearing chamber has three compartments and the chamber is pressurized by air passing through the seals at its ends. A main drainage duct drains the main bearing compartment via a scavenge pump to the oil tank. Passages through the bearings under normal operation drain oil from the end compartments to the central compartment compartment A. When the main drain becomes ineffective due to sudden surges of oil to the ends of the chamber the oil passes via auxiliary drainage ducts back to the tank due to the pressure in the chamber. Baffles are provided between the bearings and the end walls of the chamber to prevent the oil sloshing over the entrances to the auxiliary drainage ducts at excessive speed thereby providing tranquil zones from which the oil passes into the drainage ducts.

Abstract: A conveying system for bailed containers receives said containers after bail-application and with the bails supported in a substantially vertical manner advances the containers to and through a turning station. The container is first detected as to its presence on a conveyor belt and then by electric eye means a spot on the container is "read". If the spot is on the desired side no turning is performed but if the spot is detected on the opposite side the container is turned by raising a turning rail that engages the bottom rim of a container and causes the container to turn a half revolution. During turning the bail is maintained in an upright position by a magnet bar. The conveyors also may deliver bailed containers to a merge and stop unit having flow control means for delivering these containers in timed array to further processing, such as packaging.
