Abstract: A high-torque low-inertia armature for use with an electric motor wherein the armature winding is formed of aluminum conductors, and wherein a copper commutation band is formed on selected aluminum conductors in a manner to mechanically lock each commutator segment to its aluminum conductor, the locking structure being constructed and arranged to continue to function as the motor brush wears away to the top surface of the aluminum conductor.

Abstract: A tubular printed circuit armature, for use in an electric machine, is produced from two flexible cards, each card having a layer of conductive metal and a layer of insulation, such as a fully-cured epoxy-impregnated fiberglass layer. The layer of insulation is patterned in a predetermined manner to expose spaced bands of metal on the insulation side of each card, as by printed circuit techniques, so that interconnecting tabs of the winding conductors extend into the spaced bands of metal. The mating surfaces of the cards are then coated with an adhesive which will subsequently bond the cards together under a heat and pressure environment. The cards are then rolled about a high temperature coefficient mandrel, with the interconnecting tabs of one card in registry with the interconnecting tabs of the other card, and with the cards axially overlapping one another at the ends which form the axial seam of the tubular armature. The mandrel is then placed in a low temperature coefficient shell; and the shell is subjected to an elevated temperature, to thus form a unitary tube out of the two cards. The tube is then removed and the tabs are electrically connected to form the armature winding.
Abstract translation: 用于电机的管状印刷电路电枢由两个柔性卡制成，每个卡具有导电金属层和绝缘层，例如完全固化的环氧树脂浸渍的玻璃纤维层。 以预定方式图案化绝缘层，以通过印刷电路技术暴露每个卡的绝缘侧上的金属隔离带，使得绕组导体的互连突片延伸到隔开的金属带中。 然后，卡片的配合表面用粘合剂涂覆，粘合剂将随后在热和压力环境下将卡片粘合在一起。 然后将卡片围绕高温度系数心轴卷绕，一个卡片的互连突片与另一卡片的互连突片对准，并且卡片在端部处轴向重叠形成管状衔铁的轴向接缝 。 然后将心轴放置在低温系数壳中; 并且壳体受到升高的温度，从而在两张卡片之间形成一体的管子。 然后将管取出并且突片电连接以形成电枢绕组。

Abstract: A photoresist coating on a cylinder is exposed by placing a mask loosely inside the cylinder and then shining collimated light down the center of the cylinder and onto a conical mirror. The conical mirror reflects the light radially outward through the mask to expose the photoresist on the inner surface of the cylinder. Photoresist on the outside of the cylinder may also be exposed in the same manner by placing a conical mirror around the periphery of the cylinder. To expose the entire length of the cylinder, the conical mirror is moved gradually along the length of the cylinder.
Abstract translation: 通过将面罩松散地放置在圆筒内，然后将准直的光照射到圆筒的中心并到圆锥镜上，使圆筒上的光致抗蚀剂涂层暴露。 锥形镜将光线径向向外反射通过掩模，以暴露圆筒内表面上的光致抗蚀剂。 在圆柱体的外侧上的光刻胶也可以以相同的方式通过围绕圆柱体的周边放置圆锥镜来曝光。 为了露出气缸的整个长度，圆锥镜沿气缸的长度逐渐移动。
