Abstract: A motor/generator comprising a magnetic structure configured to generate a compressed magnetic field, an electrical conductive winding and a magnetic conductive winding configured to focus magnetic flux in the electrical conductive winding. The motor/generator may be advantageously employed in electromechanical and electromagnetic devices.

Abstract: This invention relates to an EMI and EMP shield configured to arrest electromagnetic contamination of sensitive electrical and microprocessor equipment. Particularly, the present invention enables a positive dynamic seal for moving parts and joints by means of resilient and self-adjusting conductive contacts. The contacts provide electrical bonding, between otherwise separate and electromagnetically leaky joints, to arrest EMI and EMP contamination.

Abstract: A portable vapor generator is disclosed that can provide a controlled source of chemical vapors, such as, narcotic or explosive vapors. This source can be used to test and calibrate various types of vapor detection systems by providing a known amount of vapors to the system. The vapor generator is calibrated using a reference ion mobility spectrometer. A method of providing this vapor is described, as follows: explosive or narcotic is deposited on quartz wool, placed in a chamber that can be heated or cooled (depending on the vapor pressure of the material) to control the concentration of vapors in the reservoir. A controlled flow of air is pulsed over the quartz wool releasing a preset quantity of vapors at the outlet.

Abstract: A compact rammer assembly for forcing ammunition into a gun having a rammer head attached to a pair of chains which are stored in separate spiral tracks positioned between the retracted position of the rammer head and driven sprockets. Each chain composed of links pinned together with vertical tabs at each end of each link; the tabs on each link engaging the tabs on adjacent links of each chain as well as the corresponding tabs on the links of the other chain when the sprockets driven the chains to extend the rammer head.
