Abstract: Abstract of the Disclosure A core holding device for rotatably holding a core on which a label strip, having separable labels to be printed and apples, is wound. The holding device includes a core holding member equipped with a plurality of flexible, resil-ient fingers for removably, resiliently holding the core so that the core and holding member rotate together. There is a mounting bracket with a circular recess for removably and rotationally mounting the core holding member. Spaced from, but attached to, the mounting bracket is a juxtaposed core looseness preventing bracket. This bracket is pivotable between a first position to provide easy access into the space between the brackets for mounting and removing the core and a second position which prevents the label strip from falling away from the core. The facing contacting surfaces of the core holding member and the mounting bracket act as two brake surfaces which contact frictionally for imparting a predetermined braking force to the rotation of the core holding member so that the label strip may be prevented from getting slack while it is being fed.

Abstract: ABSTRACT       An improved drive shaft is disclosed of the type used in a rotary fluid pressure device including an input-output shaft and a generator gear set having an externally toothed member which orbits and rotates within an internally toothed member.  Both the input-output shaft and the externally toothed member define straight internal splines, and the drive shaft includes a set of crowned, involute external splines at each end thereof, in engage-ment with the respective straight internal splines.  The crowned external splines are hobbed with a hob on which the cutter teeth have a pressure angle ?H greater than the primary pressure angle ?H of the crowned splines.  The increased pressure angle ?H of the cutter teeth makes it possible to reduce the crown angle on the splines, while  still maintaining the necessary clearance X between each external spline and the adjacent internal spline at any given axial distance Y along the external spline from the central plane.  Reducing the crown angle makes it possible either to increase the length of the external splines for a given shank diameter, or to increase the shank diameter for a given spline length.  In either case, the result is an increase in the torque carrying capacity of the shaft by a factor F, wherein F equals the ratio of sin ?H/sin ?S.

Abstract: ABSTRACT OF THE DISCLOSURE      An automatic water supply system used for raising domestic animals such as cattles, horses, poultry and so on and especially for pigs.  Instead of a water flow control means such as a valve, float or the like provided in a self supply water trough, a flow control container is used which is communicated through a water supply pipe to a common water storage tank, placed at an elevated position inaccessible to a pig or the other animals and includes a float, a valve and a siphon which may ensure the automatic and positive supply of water into the trough as the water level in the trough is lowered by an animal drinking therefrom.  Therefore the unnecessary supply of water caused by the undesired engagement of the mouth of an animal with the water flow control means in the trough mischieviously, and/or the stopping up of the drain with remaining food particles may be completely eliminated.
