Abstract: ABSTRACT            This invention deals with composite articles of predetermined contour and with methods for their manufacture.           The basic method involves providing a plurality of plies of a consolidated monotape, with each of the plies being precontoured in terms of size and degree of twist such that upon stacking the plies together, the plies provide a composite article of predetermined contour.  The plies are stacked in predetermined relationship and then diffusion bonded together under heat and pressure to provide a complex shape such as a turbine engine blade to within close tolerances.

Abstract: ABSTRACT           Method and apparatus for testing DC motors, particularly permanent magnet DC motors, involving application of a constant voltage across the motor terminals and at an earlier or later time causing a constant current to flow through the motor.  The constant voltage is applied across the motor terminals for a first predetermined time interval during a portion of which the current flow through the motor is compared with a reference level.  If the motor current falls below the reference level during the portion of the first predetermined time interval the motor is defective. The constant current is caused to flow through the DC motor for a second predetermined time interval.  If at the end of this second predetermined time interval, the DC motor terminal voltage is below a first level or above a second level, that is, the terminal voltage is outside an established voltage range, then the motor is found to be defective.

Abstract: METHOD OF AND APPARATUS FOR DETERMINING SURFACE CHARACTERISTICS, SUCH AS COEFFICIENT OF FRICTION, OF      A MOVING STRIP OF MATERIAL        Abstract of the Disclosure A method of and apparatus for testing a moving elongate strip of material to determine the coefficient of friction with respect to a control sample having known surface characteristics with a predetermined correlation to the surface characteristics normally encountered by the strip of material in use or processing and/or the proportion of increased tendsion caused by movement of the strip in contact with the control sample to the original tension in the strip are provided by this invention.  This determination is made by moving the elongate strip of material under tension of any magnitude in sliding frictional engagement with the control sample which moves in response to unbalanced force generated by the incoming tension and the sliding frictional engagement along a predetermined path of travel, preferably arcuate, until the forces exerted on the control sample become balanced at a given position along the path of travel.  The moving strip of material is guided to and from the contro sample along respective non-parallel guide paths, with the respective angles of the guide paths changing as the control sample moves along its path of travel until the angles of the respective guide paths become such, with respect to the pre-determined path of the control sample, that the forces exerted on the control sample become balanced.  The coefficient of friction of the strip of material with respect to the control sample and/or the proportion of increased tension to original tension, are determined and indicated by the position of the control sample along its path of travel when the forces exerted thereon become balanced.

Abstract: ABSTRACT OF THE DISCLOSURE.      The invention concerns a device for recording and reading the itinerary travelled through by a vehicle and in particular an automobile vehicle such as an agricultural machine.  The device is adapted to reproduce on an indicator band a trace of the path followed by the vehicle over a given surface so as to enable the operator to follow, with fidelity, in the course of a second passage of the vehicle, the trace of the preceding passage which permits, for example in the case of spraying, a rational treatment of the surface to be treated in strictly parallel strips with no omission or overlapping of zones.  The device comprises a programmer constituted by the indicator band which travels at a speed which is proportional to the speed of the vehicle in front of a movable recording element which is controlled by the steering of the vehicle and reacts in accordance with the variations in the steering. The device further comprises a device for reading the recorded program and a device for indicating and displaying the suc-cessive directions assumed by the vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE                A duct section or other load to be moved axially along a bore hole has two reciprocating drivers mounted on it and two sets of gripping elements.  Each driver reacts axially between the load and a set of gripping elements to move the gripping elements relative to the load through a defined stroke in each axial direction.  An endless cable with axially extending straight stretches has one stretch connected to each driver to constrain the drivers always to move in opposite axial directions and to begin and end their strokes simultaneously.  The gripping elements are so formed that when engaged with the surface of a bore hole, increasing axial force on the load in one direction increases the radially outward force under which they bite into the surface.  At each end of a driver stroke the gripping elements collide with abutment members of a direction control device, whereby gripping elements engaged with the bore hole surface are forced out of such engagement and dis-engaged gripping elements are forced against that surface.  The abutment members are arranged in two sets, one set to coordinate gripping element engage-ment and disengagement for transporting the load in one axial direction, the other set for transportation in the opposite direction.  Positioning the directional control device at one or the other limit of its rota-tion brings one or the other set of abutment members into use.
