Abstract: A new kind of greeting card uses the stock removed from a cut opening to create a raised portion on another page. To make the card, a die cuts around a portion of the perimeter of an area on the stock that will be transferred to form the raised portion of the card. This transfer area is temporarily left in place in its original position on the stock. Adhesive is applied to an adhesive area on either the back of the transfer area or on the portion of the stock that will form the page where the transfer area will be adhered. When the stock is folded into a card, the adhesive is sandwiched between the back of the transfer area and the portion of the stock where the transfer area is to be adhered. When the card is opened, the transfer area is separated from its original position, creating a cut opening on one page of the card. The adhesive holds the transfer area to the other page, creating a raised portion on that page. In a multi-page card, transfer areas from multiple pages can be stacked on top of each other.

Abstract: Stepping motor techniques are made viable for heavy duty machines with variable speed operation (motors or generators) by reason of the simplification and gain in specific output and efficiency which results from constructions ensuring maximum saturation of magnetic flux at the stator pole faces and with minimal airgap between the associated stator and rotor pole faces. The density of the ferro-magnetic material forming the arcuate faces of the rotor poles may be varied (graded) circumferentially of said faces and the poles relatively shaped and arranged so as to render possible uni-directional current, 2-phase operation. Energy stored is minimised and the reduced energy inductively stored is returned to the source by vestigial coupled windings. Uni-directional currents only flow in the windings, and the switching circuitry, although not fundamentally novel, is greatly simplified.
