Abstract: Resilient magnetherapy articles having a powder-like filler material including magnetic elements contained within a resilient bladder are disclosed for exercising the muscles of the wrist, hand, fingers and forearm of the user, and for supporting the wrist of a person performing repetitive tasks with their wrist, hand and fingers, such as using a computer mouse and typing on a keyboard, while at the same time providing the beneficial effect of magnetic therapy. A mass of tiny glass spheres having the consistency and appearance of a fine powder is enclosed in a resilient inner bladder surrounded by a resilient outer bladder and a thin layer of lubricating powder is disposed between the exterior surface of the inner bladder and interior surface of the outer bladder to prevent them from sticking together, reduce friction therebetween, and allow relative sliding movement between the surfaces when squeezed in the palm of the hand.

Abstract: A process for manufacturing filled resilient double bladder articles wherein a thinner walled resilient outer bladder and thicker walled resilient inner bladder are formed and a lubricating powder layer is deposited on the exterior surface of the inner bladder. The outer bladder is superposed over the inner bladder to form two plies of resilient material separated by the thin layer of lubricating powder which prevents the superposed surfaces from sticking together and allows relative sliding movement therebetween. The superposed bladders are pressed to remove any trapped air between the bladders and are then inflated to radially stretch them as a unit sufficient to cause permanent deformation thereof and thereafter allowed to deflate so that after deflation the deformed superposed bladders are of a size sufficient to contain a predetermined volume of filler material. The double bladder article is filled with a mass of tiny glass spheres having the consistency and appearance of fine powder.

Abstract: A resilient wrist support and therapeutic hand exerciser device for supporting the wrist of a person performing repetitive tasks with their wrist, hand and fingers, such as using a computer mouse and typing on a keyboard, and for exercising the muscles of the wrist, hand, fingers and forearm of the user. A mass of tiny glass spheres having the consistency and appearance of a fine powder is enclosed in a resilient inner bladder surrounded by a resilient outer bladder and a thin layer of powder is disposed between the exterior surface of the inner bladder and interior surface of the outer bladder to prevent theme from sticking together, reduce friction therebetween, and allow relative sliding movement between the surfaces. The tiny spheres provide low resistance to relative particle movement by rolling on each other upon an increase or decrease in pressure applied to the device.

Abstract: A therapeutic resilient hand exerciser and method of manufacture is disclosed. A mass of tiny glass spheres having the consistency and appearance of a fine powder is enclosed in a resilient inner bladder which is surrounded by an outer resilient bladder and a thin layer of powder is disposed between the exterior surface of the inner bladder and interior surface of the outer bladder to prevent the surfaces from sticking together and allow relative sliding movement therebetween. The tiny spheres roll on each other upon squeezing and releasing pressure on the exerciser to provide low resistance to relative movement and allow the exerciser to be compressed quickly and to resume its natural shape quickly due to the resiliency of the superposed bladders, and thereby produces a smooth squishy sensation.

Abstract: A positionally adjustable strut connector for a kite is disclosed in which the connector has a first body member hingedly connected to a second body member. One body member is adapted to receive a wing strut while the other member is adapted to receive the cross or bracing strut.

Abstract: A keel guided acrobatic kite and control apparatus are disclosed in which a reference point included on the keel of the kite is maintained no more than a fixed maximum distance from reference locations included on the body of the kite. Stabilizer lines are secured between the reference location on the keel and each of the reference locations on the body. When the kite is in a nominal flying position, the keel is disposed essentially perpendicular to the body of the kite, and the stabilizer lines are taut. Two control lines are received by guidance structure connected to the reference location of the keel. One end of each control line is secured to one of the reference points on the body. In operation, one of the control lines is pulled, causing the reference point on the keel to move toward one of the reference points included on the body. The stabilizer line connected to that reference point slackens while the other stabilizer line remains taut.

Abstract: A box-like kite formed of a single strut on which a pair of airfoils are pivotally connected in spaced relation. Each airfoil is constructed of a rectangular sheet of formed plastic folded into a generally triangular, hollow, open-ended box having curved walls.
