Abstract:
This freight lashing apparatus comprises freight contact bail means responsive to freight movements in a forward and in both lateral directions. An unlocking means is responsive to freight movement in a reverse direction. The freight contact bail means and the unlocking means are both operatively connected to freight locking means to retract the freight locking means and the bail means below the loading floor so as not to interfere with the freight movement, especially in an aircraft.
Abstract:
The present gas dynamic laser device is provided with an expansion chamber arranged between a heating chamber for the COgas and the resonance chamber. The expansion chamber is initially evacuated for producing a rarefaction wave. Between the heating chamber and the expansion chamber there are arranged rapid release means such as a valve or a diaphragm. Pressure recovering means are connected to the other side of the resonance chamber.
Abstract:
The present torque motor, especially for controlling the rudder gear of a flying object, such as a missile, comprises a crossshaped armature preferably having four free ends which cooperate with respective electromagnets to impart movement to the armature in reponse to the size and direction of current flowing through the energizing coils of the magnets. The armature is supported substantially in its center of gravity by pivot bearing means permitting a universal, pivotal movement of the armature relative to said magnets. In one embodiment bounce or deflection plates are carried, preferably adjustably, by said free ends of the armature and each of these plates cooperates with a respective one of a corresponding number of nozzle means for controlling the position of rudder blades.
Abstract:
An ignition device having an ignition sequence including fuse elements preventing an unintentional release of the pyrotechnic composition. The ignition sequence is fed with voltage by a turbine generator upon reaching a predetermined rotation speed. The turbine generator is supported movably as a part of the ignition sequence in relation to a fuse element and is movable into its position which unlocks the ignition sequence to a pyrotechnic composition which is fed by the generator voltage through a threshold gate member.
Abstract:
Magnetic suspended and guided railway. In a magnetically suspended railway, the suspending magnets can also be used for lateral guiding where said magnets are located along opposite sides of a given vehicle and cause to cooperate for the purposes of the desired suspension with magnets or magnetic rails arranged along the sides of the desired path of travel. Lateral guiding thereof is accomplished in one embodiment by offsetting the magnets somewhat from the center of the magnetically conductive rail which causes said magnets to generate a laterally directed force as a result of their tendency to center themselves with respect to said rail. By placing similar magnet and rail relationship on both sides of a vehicle, and by appropriately adjusting the degree of energization of said respective magnets, the laterally directed forces may be balanced as needed for straight-away travel or unbalanced as needed for travel around curves. Alternatively, pairs of laterally arranged magnets may be centered with respect to the magnetically conductive rail and one thereof energized more than the other by which similar laterally directed forces will be generated as a result of the tendency of the entire magnetic unit to center itself with respect to the rail. This structure may likewise be repeated on the opposite side of the vehicle and the forces balanced or unbalanced as required.
Abstract:
In the magnetically suspended railway system disclosed, magnetizable carriers suspended from under each side of a railroad car, support lift and traction magnets and side-to-side guide magnets which are electrically controlled to move along the underside and upright of an inverse-T shaped magnetizable rail mounted from the tops of stationary C-shaped rail supports. Slide surfaces on the rail supports, which are more closely spaced to the carriers than to the car bottom, hold up the train at the carriers in the absence of magnetic force. At switch areas where the rails diverge into two pairs, stationary lift magnets engage the carrier and guide the car along the desired directed. Interlaced non-touching fingers magnetically couple the carriers from one car to the other.
Abstract:
A traffic system utilizing a magnetic repulsive system to support a vehicle on a rail. The guide system for the vehicle permits the vehicle to move from a condition wherein there is little or no gap between the track and the vehicle to a condition wherein a required air gap is provided between the track and the vehicle, which change in condition may occur without any substantial reduction in speed.
Abstract:
Lateral guide means for a magnetically supported and track controlled vehicle. In a magnetically supported vehicle lateral guide means are provided for guiding same both along a straight or slightly curving portion of a track and for guiding same through a switch. One set of magnets is provided along one side of the vehicle and another set of magnets is provided along a guide rail adjacent the track. In one embodiment, either of said sets of magnets is a set of electromagnets and the other is a set of permanent magnets while in another embodiment all magnets are electromagnets. A similar arrangement is provided on the opposite side of the vehicle. By creating repelling forces between some of said magnets and attracting forces between others thereof, an accurately controllable lateral guide is developed for said vehicle by which same is caused to maintain an accurately controllable spacing between the vehicle and the side guiding means. A further modification includes combinations of linear motors on either side of the vehicle together with guiding magnets between the vehicle and a laterally positioned track.
Abstract:
Blade control means primarily for rotary-wing aircraft. There are provided two control plates coaxially positioned on a common axis and each subject directly or indirectly to manual control. A first thereof is arranged for universal movement about a substantially fixed center located in said axis and the other thereof is arranged for movement in and along said axis at a substantially fixed orientation, usually normal, to said axis. At least three or more voltage changing devices operable in response directly to linear motion are arranged between said plates and positioned at equal angular spacing therearound. The output of said voltage changing devices is then conducted to means for controlling servomotors which in a conventional manner control the blade angle of the wings of said rotary-winged aircraft.
Abstract:
A braking system for high acceleration operated free pistons comprises a cylinder having one end with an inturned flange which provides a stop or abutment for a deformable shell in the form of a cylinder which is opened at each end. The piston, which is freely movable in the cylinder in a direction toward the shell is provided with a concave face on the side facing toward the shell and with a rim which engages behind an inwardly turned rim of the braking shell. The shell is deformed inwardly into the concave recess of the forward end of the free piston upon the impact of the piston against the shell and the deformation of the shell provides a shock absorption for the impact of the piston.
