Abstract: SEPARATING APPARATUS                       ABSTRACT   Harvesting apparatus comprising a mobile frame, and stripping means for detaching from standing crop predetermined required parts of the crop such as grain, leaving stripped stems in the field.  The harvested crop mixture contains a high proportion of free grain which has been threshed by the stripping means, and this is separated from the crop mixture before the crop mixture is passed to the threshing drum.  In one form of the invention an apertured screen 40 is provided beneath a transverse conveying auger so that free grain passes through the screen while the crop mixture is being conveyed towards the threshing means.  Separated free grain is collected and transported to the normal cleaning and separating mechanism of the combine harvester after the threshing drum.

Abstract: ABSTRACT A subsea casing hanger suspension system has one or more casing hanger assemblies for supporting and transmitting the load of their concentric casing strings on and to a subsea wellhead housing.  A split ring type multiple shoulder load ring is part of the hanger assembly.  The load ring is radially expanded from its contraction condition.  The annuler load ring has an angular cross-section configuration which precludes inadvertent activation of the ring by upward and downward loads imposed upon it.  When the casing string in its hanger assembly, containing the ring are being lowered downhole during installation in the well.  The load ring as expanded by contact with a previously installed annulus packoff, geometry of the load ring is shaped to prevent its accidental radial engagement with the surrounding riser couplings and/or other elements through which the hanger assembly and its casing string descend during installation.

Abstract: INFLATABLE PLAY BALL          Inventor:  Donald Spector, a citizen of the United States and resident of Union City, NJ                  ABSTRACT OF THE DISCLOSURE           A child's play ball constituted by an outer casing and an inner inflatable bladder.  The outer casing is formed by contoured segments of high strength, non-stretchable fabric material stitched together to define, when the casing is fully expanded, a play ball of the desired shape and size, such as a football or soccer ball.  The inner bladder is a conventional rubber balloon whose stem initially projects through an opening in the casing which is provided with a closure.  The stem, after the balloon is inflated with air so that it conforms to the casing, is then tied to retain the air, the tied stem being concealed within the casing by the closure.          The maximum safe diameter of the inflated balloon which is well below the diameter at which the balloon is close to its bursting point, is approximately equal to the maximum dimension of the expanded casing whereby the encased balloon has excep-tional strength and the play ball may be subjected to rough handling.
