Abstract: A machine translates torque applied to the input shaft at an input speed (RPM), first into kinetic energy, and finally to torque on an output shaft. The input power is first converted to kinetic energy by accelerating a mass or masses, so that the reaction force to this acceleration is an oscillating bi-directional torque or force. This torque or force is then converted to a unidirectional torque applied to an output shaft. This arrangement provides a continually variable automatic transmission, or torque converter in which output shaft speed is proportional to the input shaft speed and inversely proportional to the load applied, and in which transmitted torque corresponds to the input shaft speed.

Abstract: This novel Head Mounted Display (HMD) has a removable communications unit which can be interchangeably worn on the right or left side of the user. Thus, users having a hearing deficiency in one ear can use the opposite ear. Also, the HMD has a fully adjustable eyepiece which can be swung out of the way when not in use or can be used adjacent either eye. An important feature of this invention is an eye guard which prevents the eyepiece from striking the user's eye or face portion.

Abstract: A closure device providing tactile confirmation of occlusion is disclosed. The closure device comprises first and second interlocking fastening strips arranged to be interlocked over a predetermined length, at least one of the fastening strips having a deformation in the closure device after occlusion of the closure device. This deformation allows a user to tactually confirm that the closure device has been occluded, even after the closure device has been occluded. The deformation may be an inward deformation or an outward deformation on the fastening strip. The deformation may be on one or both of the fastening strips. The fastening strip may include multiple deformations. The deformation may be facilitated by providing a flexure point in the fastening strip, such as, an area of reduced cross-section or a coextruded portion with a different modulus of elasticity. In one embodiment of the invention, the fastening strips include mateable male and female closure elements.

Abstract: A missile launcher assembly for launching a missile from an airborne, shipborne, or ground-installed platform has a carriage mounted for limited forward and rearward movement on a track provided on the platform. The carriage supports the missile in fixed relation to the carriage by hooks having an inclined surface that engage mating surfaces within the missile body and a pivotally mounted restraint pawl that engages a surface within the missile body so as to keep the missile from sliding off the hooks. A camming surface engageable with a pawl-restraining rocker link is located on the platform so that when the missile and carriage are moved forward upon ignition of the missile motor, the front end of the link is cammed downward, forcing its rear end upward and releasing the pawl. The pawl, upon being released, rotates upward out of the missible body, allowing the missible to slide off the hook.
