Abstract: A method for producing a neutrons includes triggering a raising or a lowering of a temperature of a pyroelectric crystal of less than about 40° C. to produce a voltage of negative polarity of at least ?100 keV on a surface of a deuterated or tritiated target coupled thereto. A deuterium ion source is pulsed to produce a deuterium ion beam. The accelerating of the deuterium ion beam is achieved by accelerating voltage of the pyroelectric crystal toward the deuterated or tritiated target to produce neutrons. Furthermore, the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source are coupled to a common support. The method also includes throwing the common support housing the pyroelectric crystal, the deuterated or tritiated target, and the deuterium ion source near an unknown threat for identification thereof.

Abstract: A cylinder lock includes a latch retractor housing having inner and outer cover plates, inner and outer drive spindles extending respectively through the inner and outer cover plates, a sleeve surrounding the outer drive spindle and having a flange contacting the outer cover plate, an outer shell surrounding the inner drive spindle and the latch retractor housing, and at least one rigid coupling member or tube disposed within the outer shell and engaging and coupling together the inner and outer cover plates and the flange, thereby reinforcing the outer drive spindle and the latch retractor housing and increasing torsional and compression strengths thereof. A reinforcing ring is further provided to couple the outer drive spindle to the outer handle for reinforcement.
