Abstract: A pointing error compensating device for compensating the error induced in a position indicator as a result of forces acting on a structure, such as gravitational forces acting on a large antenna having a reflecting dish, that is pivotal about an elevation axis.The error compensating device comprises a torque producing device having a moment arm in the form of an eccentric mass attached to a shaft coupled to the structure, the shaft being rotatable in response to a pivotal movement of the structure. The shaft is also coupled to a drive shaft of the position indicator. The eccentric mass is attached to the transmission shaft in such a manner that it applies a torque to the latter which is proportional to the cosine of the angular orientation of the structure about the elevation axis. The transmission shaft is deflected torsionally by the eccentric mass in an amount which is designed to be approximately equal and opposite to the error which otherwise would be induced into the position indicator.

Abstract: A quick-connect tubular coupling for a pair of tubes one of which has an end portion telescopically disposed within an end portion of the other. An annular cage is externally mounted on the one or inner tube in axially spaced relation to the free end of its end portion. The cage is held on the one tube against axial displacement along the latter. The end portion of the other or outer tube is flared outwardly at its free end and extends in the cage. A circular spring means is interposed between the flared end portion of the other tube and the cage and when so disposed prevents axial movement of the one tube relative to the other in telescopic disengagement direction. Between the telescoped end portions are a plurality of "O" rings that are compressed in a sealed mode to prevent leakage through the coupling.

Abstract: A flexible, pneumatic bumper adapted for motor vehicle applications. A plurality of individual chambers are defined by a resiliently deformable outer bumper shell, a supporting plate secured to the vehicle structural members and a plurality of baffles or separator elements extending from the bumper shell toward or to the mounting plate. When the outer bumper shell is displaced inwardly due to an impact force, resultant chamber deformation causes an increase in chamber pressure that is relieved by air being forced out of the chamber to an adjacent chamber or to the atmosphere through a pressure relief valve. Following impact, return of the bumper shell to its original shape is slowed by a restricted return air flow into the chambers thereby preventing bumper rebound forces.The separator elements may be designed to provide a preloading effect or a maximum buckling resistance when the bumper shell is installed on the supporting plate.

Abstract: A cylinder head having an exhaust valve port comprising a throat defined by a wall of substantially circular cross section and a bevelled valve seat circumscribing the wall. The bevelled valve seat has an axially extending annular portion adapted to be engaged by a valve head to close the port, the bevelled valve seat extending axially outwardly from the axis of the throat at an angle to the wall. The improvement comprises the application of a small wall diverter within the exhaust port to force separation of the high temperature exhaust gas stream from the exhaust valve seat when the valve is open.

Abstract: Apparatus for supplying an air-vapor mixture to an air intake chamber in communication with an air intake passageway of a carburetor under acceleration conditions of an internal combustion engine. The air intake chamber has a valved inlet opening through which normal atmospheric air is supplied to the carburetor under normal operating conditions. Upon operation of the accelerator control means, a steam or vapor operated air injection means is actuated. The steam or vapor is admixed in the air injector nozzles with the mixture being discharged into the air intake chamber. This increases the pressure in the chamber causing the valve in the atmospheric air inlet to close. The air-vapor mixture then becomes the sole air supply to the air intake passage of the carburetor.

Abstract: A vehicle seat assembly comprising a substantially horizontal seat structure and a normally upright backrest structure. The backrest structure is carried on support arms pivotally connected to the seat structure for swinging movement about a fixed pivot axis extending laterally of the latter. A four-bar linkage adjuster mechanism is interposed between the seat structure and the backrest structure. The four-bar linkage of the adjuster mechanism terminates in a movable abutment engageable by an abutting portion of the backrest structure. Under control of the linkage the abutment is movable in the path taken by the abutting portion of the backrest when the latter is swung rearwardly from its normal upright position to a predetermined rearwardly inclined position.A releasable brake means holds the four-bar linkage and thereby the abutment against movement to block rearward inclination of the backrest structure.

Abstract: A vehicle body having a window opening, a window well subjacent the opening, and a vertical inner body panel forming a wall of the window well. A window panel supported on a bracket is provided for the window opening.Of importance is the provision for selectively positioning the window panel on the bracket and the bracket on the body panel. This is accomplished by a first series of fasteners for securing the window panel to the face of the bracket and a second series of fasteners for securing the bracket to the body panel. Both series of fasteners pass through a plurality of correlated slots for permitting, prior to final tightening of the fasteners, vertical movement of the window panel relative to the bracket, and fore or aft and inboard or outboard movement of the bracket relative to the body panel.

Abstract: Carburetor power valve control apparatus for an internal combustion engine. The control apparatus includes a vacuum motor and temperature sensitive power means. The power means opens and closes a vacuum bleed port in communication with the vacuum motor so that under cold operating conditions the power valve opens at a greater actual intake manifold vacuum than under warm operating temperatures. This results in earlier power valve opening at cold engine temperatures which improves drivability and allows balancing of all carburetor fuel systems to achieve improved fuel economy and reduced engine emissions.
