Abstract: Described in this specification is a shock tube initiator that is suitable for one, two, or more shock tubes. The initiator has a number of safety features to avoid inadvertent firing of the shocking primer. Features include a rotary safety and a firing plunger that selectively interfere with the firing pin. There may further be a safety pin for fixating the rotary safety onto the housing of the initiator, so users must deliberately remove the safety pin before the rotary safety can be disengaged.

Abstract: A three-wheeled vehicle includes a frame including a longitudinal axis and a steering head, an engine-transmission assembly coupled to the frame, a steering assembly pivotably coupled to the steering head, a front wheel rotatably coupled to the steering assembly, a rear axle assembly, a control arm coupling the rear axle assembly to the frame, a pair of rear wheels rotatably supported by the rear axle assembly, and a substantially laterally-extending link interconnecting the rear axle assembly and the frame to control lateral motion of the rear axle assembly relative to the frame.

Abstract: An elongate explosive charge element (25), said explosive charge element (25) including a flexible frangible cutting sheet (26) and an explosive agent (27) said charge element (25) adapted to the penetration of a barrier structure.

Abstract: The data processing system includes a property inspection data entry device for collecting and storing inspection data during the inspection of a property. The property inspection data entry device typically includes a scanner which is responsive to labels which are associated with the property as well as various items located about the property which include indicia representative of predetermined characteristics of the rental unit. The property inspection data entry device also includes a data entry device, such as a keypad, for providing manual entry of additional inspection data. The data processing system can also include a maintenance data entry device for collecting and storing maintenance data relating to maintenance activities performed on a property. The data processing system also includes a host computer for electrically communicating with the property inspection data entry device and the maintenance data entry device prior to and subsequent to inspection and maintenance activities, respectively.
