Abstract: ABSTRACT OF THE DISCLOSURE         An improved mechanical planting machine capable of making a furrow in the ground and planting therein plants with root clods such as so-called pot-type plants.   The apparatus comprises a plowshare for forming a furrow, feeding apparatus for feeding the plants into the furrow, compressing means such as pressure wheels for compacting the soil against  the roots of the plant, and an operating device for supporting the plant in the selected planting position while the soil is being com-pacted.  The operating device is the inventive feature.   It comprises two parallel circulating endless elements located above the furrow with flexible wires attached at regular inter-vals.   The device is located above the furrow so that the wires dangle down forming two parallel wire walls that penetrate the furrow and support the plant therebetween until the soil has been compacted.

Abstract: X-ray equipment for nondestructive testing and particularly for mechanized testing of the integrity of welds along the length of the welds includes means for mechanically traversing an X-ray source along one side of the weld and a grainless fluorescent screen along the other side, with the screen coupled to an image-isocon video camera, preferably through a light intensifier.  The equipment includes means for display of the X-ray shadow-picture from the video camera and for super-imposing identifying indicia, along with means for recording the composite of the indicia and the picture,  The image is preferably integrated over at least several frames so as to minimize "noise" and intensify contrast.  In addition, a signal from an ultrasonic transducer may be provided to indicate to the operator the existence of a probable flaw in the weld metal.

Abstract: Abstract of the Disclosure A method for making a steel belted radial ply tire having a 0° cap band in a single stage is disclosed.  Two plies of body tire cords are wound around a tire building drum to form a cylindrically shaped body layer, the body tire cords extending substantially parallel to the axis of the drum.  Two plies of bias angled substantially in-extensible steel breaker tire cords are then serially wrapped around the radially outer surface of the body layer to form a breaker, the breaker tire cords being parallel in each ply and oppositely disposed in the two plies and form-ing an angle of between about 30° and about 70° with the plane orthogonal to the axis of the drum.  A strip of high "soft stretch" reinforcing cord tape is then helically wound around the radially outer surface of the breaker for a select-ed plurality of full turns at an angle of substantially 90° relative to the axis of the drum, to form a cap band having a desired axial width, the tape being made up of a plurality of substantially inextensible cords disposed in side by side re-lation to one another and being longitudinally extensible pre-ferably by between about 30% and about 75% without stretching the cords thereof.  A tread slab is then wrapped around the radially outer surface of the cap band so as to provide a raw, cylindrically shaped, tire carcass having a diameter which is substantially less than the diameter of the crown region of the corresponding cured, toroidally shaped, completed tire.
