摘要:
An ETC igniter and compatible electrical connector for enabling an ETC gun to be used in a battlefield setting in close proximity with personnel and sensitive electronic equipment. This is accomplished by providing a current path to and from the igniter that is electrically isolated from all other portions of the gun. The connector and igniter are adapted to be capable of withstanding the high connection forces necessary to prevent arcing and the extreme stresses imposed during firing of the gun.

This invention relates to thioformamide derivatives of the formula: ##STR1## wherein R represents alkyl, Ar represents optionally substituted phenyl, Y represents an ethylene or methylene radical or a valency bond, and n represents 0 or 1, bioprecursors thereof and pharmaceutically acceptable salts thereof which possess useful pharmacological properties, processes for their preparation and compositions containing them.
摘要:
Embodiments of a phased array antenna having a plurality of unit cells, each unit cell utilizing an improved electromagnetic band gap (EBG) structure and a lossy material in connection with the EBG element are disclosed. The lossy material reduces the undesired coupling between the antenna radiator and the EBG, thus providing enhanced scanning performance in the phased array aperture.

摘要:
A link asssembly includes a jointed arm terminating in a barrel portion at one end and a collar portion at the opposite end. The barrel portion is mounted to a control arm by a fastener. The collar portion receives a tubular stabilizer bar. During operation, the jointed arm provides a working angle large enough to accommodate the movement between the stabilizer bar and the link assembly.
