Abstract: ABSTRACT OF THE DISCLOSURE            A subcircular type rotor is disclosed comprising an axial central hub, radial webs supported by the central hub and each including a mass localised at the outer end of the web which mass constitutes the major part of the total mass of the web, and a subcircular rim supported on the webs, wherein the radius of curvature of the sectors of the rim between each pair of consecutive webs is greater than the outer radius of the webs and the size of the localised masses is selected so that the centrifugal force that they exert when the rotor rotates counteracts the radial compressive force which the subcircular rim exerts on each web inwardly towards the hub when the rotor is stationary,  In a rotor according to the present invention, the radial stresses exerted on each web may advantageously be reduced as compared to prior art rotors.

Abstract: ABSTRACT OF THE DISCLOSURE      An earth boring drill bit has a lublicant pressure compensator that includes a plunger that moves slidingly in the reservoir to reduce pressure differential, and also allows lubricant to bleed past to relieve excess lubricant pressure.  The plunger is carried slidingly in the reservoir.  The plunger has a convex end in contact with the lubricant and a concave end in contact with the borehole fluid.  The plunger has a rod that contacts a stop in the reservoir when the lubricant pressure is greater than the borehole pressure.  Once stopped, the configuration of the plunger allows lubricant to bleed past the plunger to relieve excess lubricant pressure.

Abstract: ABSTRACT OF THE DISCLOSURE        A power driven twin trowel cement finishing machine in which two sets of counter rotating troweling blades have intersecting circular trowling area, each set of troweling blades being carried by a rotatable shaft upon which the blades are supported and arranged for remote relative adjustments from a guiding handle of the sets of troweling blades to vary their troweling angle with respect to the associated cement surface.  The two sets of trowel-ing blade assemblies have their rotatable shafts supported for relative tilting movements in opposite directions from a normal generally vertical position to selectively oppositely inclined planes of rotation of the sets of troweling blades in a manner to generate reactive blade forces that will be operative to bodily propel the machine either in a forward or reverse direction, while permitting manual lateral controlled movements of the machine by means of the guiding handle.  Remote control mounted on the guiding handle is operable to vary the orientation of the planes of rotation of the sets of troweling blades and the consequent propelled direction of movement of the machine.

The mounting flange terminates in a hub.  Also included is an annular friction flange connected to the hub.  A first outer shell section is rotatively mounted on the hub and connected to a second outer shell section with fan blades connected thereto.  A circular face plate is connected to the second outer shell.  A circular piston is axially and slideably mounted on and within the second outer shell section and axially of the face plate thereby forming a cylinder void between the piston and the face plater  A circular resilient bladder member is secured at its peri-pheral edge portion between the second outer shell section and the face plate with the bladder adjacent the piston and opposed to the face plate.  The piston has a ring of friction material  connected thereto.  A series of spaced springs are mounted between the first outer shell section and the piston for urging the ring of friction material from the friction flange.  Fluid pressure is introduced by means of a rotary air union into the cylinder void between the face plate and the bladder to cause the friction material ring to engage the friction flange to thereby rotate the first and second outer shell sections and the fan blades carried thereby against the action of the springs.

Abstract: ABSTRACT:         "Apparatus for examination by means of scattered radiation".     The invention relates to an apparatus for imaging a layer to be examined of a body irradiated by primary radiation, which layer emits scattered radiation, which apparatus comprises a diaphragm plate which is disposed outside the primary beam, which is rotatable about an axis (7)perpendicular to its major surface, and which has at least one aperture which is disposed off the axis of rotation, and a detector or a superposition device for measuring or superimposing the scattered radiation which passes through the diaphragm plate at different aperture settings. The primary radiation (3) is stopped down to form a flat fan-shaped beam, the diaphragm plate (6) extending parallel to the fan-shaped beam. Each aperture (8) corresponds to an associated detector (9), which follows the rotation of the diaphragm plate and whose input face extends parallel to the diaphragm plate, said detector being arranged so as to be rotatable about a detector axis (10) which is perpendicular to an input face and extends through its centre, in a direction opposite to the direction of rotation of the diaphragm plate and with the same angular velocity as this plate.

Abstract: ABSTRACT OF THE DISCLOSURE        A process for producing a valve-and-lid assembly con-sisting essentially of a lid and a valve body, comprises the steps of (A) producing, in finished conditioned, the said lid with a collar portion having a shoulder or a rim about a central opening.  (B) producing separately, in finished condition, the said valve body having an upper body portion preferably bearing a dowel portion, and on the latter a valve stem bearing at its free end a valve head of enlarged diameter, (C) mounting the valve body on the mandrel of a piston movable in a pressure cylinder aligned with the central axis of the valve-and-lid assembly, or placing it loosely in said collar portion above said central opening, (D) striking the mandrel with sufficient force, e.g. preferably 15 to 25 kilopond, to drive the sane together with the valve body abruptly through the collar portion of the lid and to pass the valve head out of the said central opening with stretching or bending the valve stem or an adjacent part of the valve body, so that, upon with-drawel of the mandrel, a rearward face of the valve head sealingly engages the shoulder or rim about the central opening.          The self-closing valve-and-lid assembly which can be produced by this process is adapted for closing the open top end of the interior of a container fillable with pressurized product and comprises a lid having a dome part and a collar portion on the latter, as well as a valve body mounted in the hollow interior of the dome part and being of elastically flexible material.
