Abstract: A digit splint, for partially immobilizing a digit, such as a finger or a toe, for therapeutic purposes. The digit splint of the present invention is of laminate construction having a base layer, a semi-rigid or rigid layer, and a covering layer. The base layer carries an adhesive for securing the splint to the digit. The semi-rigid or rigid layer, in one embodiment, is constructed of a heavier gauge polyester, or plastic, film. The covering layer is adhered to the base layer, with the semi-rigid or rigid layer sandwiched there between, and provides a, preferably, water-proof covering for the digit splint.

Abstract: A mattress comprises a base unit. A topper is supported above the base unit. The topper comprises an elongate rectangular body having a center zone joined between opposite end zones. The topper is of a select foam material of substantially uniform firmness and the center zone has a density greater than density of the end zones. A cover fabric layer surrounds the base unit and the topper.

Abstract: A bedding product for use as a mattress topper has a tray formed by a bottom sheet of compressible material with a generally rectangular frame attached at the periphery of a surface thereof, formed by rails of compressible material. The tray has a generally rectangular recess therein formed by the rails, which can be filled with inserts of selected firmness characteristics, to give the overall bedding product selected characteristics related to firmness.

Abstract: A method of making a foam encased innerspring mattress and an innerspring mattress made according to the method. The method includes the steps of assembling the sides and bottom of a foam housing, positioning an innerspring unit in the housing, securing a foam layer to the top of the housing, and sealing the innerspring unit therein. A quilted covering is applied over the completed assembly. According to the method, a foam encased innerspring mattress can be made in any desired firmness, and any desired size or shape, including standard bedding sizes and shapes.

Abstract: A multitrack coupled element read head and a method for manufacturing such a read head are provided. The multitrack coupled element read head includes multiple coupled magnetoresistive read elements in a spaced relationship, and a support structure between a pair of coupled read elements, the support structure also being a magnetoresistive material. The read head also includes a closure material bonded on the plurality of coupled read elements and the support structure, where the support structure provides for substantially even pressure on the pair of coupled read elements such that shorting therein is eliminated.

Abstract: An arbor is formed with uniformly-spaced splines each of which has a cross-section in the shape of an asymmetric trapezoid. The leading force transmitting face of each of the splines is disposed at an angle lagging by about seven degrees from a truly radially-extending plane of the arbor. The trailing face of each of the splines is disposed other than in a generally radially-extending plane of the arbor. A circular saw blade mounted on the arbor has a central opening or eye formed with complementarily shaped recesses such that the arbor splines fit within the recesses in the eye for transmission of torque from arbor to saw.
