    摘要： A compact AC-DC motor comprising a housing having a center section and respective end bells, each having a recess therein. A stator is received in the housing and extends into the recess in one end bell and a magnetic pole piece is similarly received in the housing and extends into the recess in the other end bell. Rotatably supported in the end bells is a shaft which mounts a rotor which cooperates with the stator, and an armature winding in juxtaposition to the rotor which cooperates with the pole piece. Additionally, a brush holder is affixed to the end of the pole piece whereby the construction provides a highly efficient motor which occupies a minimum volume of space.

    摘要： A variable pressure control switch for a battery charging circuit is provided which includes a housing that receives a first member. A chamber is provided in the first member and a diaphragm extends across the chamber to divide the chamber into first and second portions. A first passage communicates with the chamber first portion and extends through the first member and is adapted to be connected with the interior of the battery to be charged so that the interior pressure of the battery is applied to the diaphragm. A second passage is provided in the first member which communicates with the chamber second portion and a piston is slidably received in the second passage. The piston is movable by the diaphragm between a first and a second position. Variable force biasing means engages the piston to prevent movement of the piston to the second position until a preset pressure has been exceeded. Switch means is operable by the piston when the piston is moved to the second position to control the associated charging circuit.
