Title: Suspendible carrier for carrying multiple cargo loads by helicopter
Inventor: NYKIFORUK DONALD TERRY
IPC: B64D1/22
Filed: 1997-08-12
Abstract: A suspendible carrier is provided for receiving and carrying cargo from an aircraft. A detachable ground assembly releasably engages cargo to the carrier, and has a coupling means consisting of an elongate vertically-oriented shank having a coupling, such as a widened head, at its upper end. A pylon or other support structure holds the coupling in a vertical position prior to pickup by the helicopter. A cargo suspension assembly is suspended from the cable, and has a coupling engagement apparatus to releasably engage the coupling. The coupling engagement apparatus has a receiving portion to engage the coupling and a retaining portion to retain the coupling. The receiving portion may consist of a panel hinged with a one-way hinge to the engagement apparatus. The coupling is transported from the receiving portion to the retainer portion, preferably by maintaining the coupling engagement apparatus in a rearwardly-tilted orientation to permit couplings to slide towards the retainer portion. A release mechanism selectively and individually releases couplings from the suspension assembly. Preferably, the cargo suspension assembly has an elongate shape adapted to retain multiple cargo carriages. The cargo release mechanism may comprise a release arm and a keeper, both of which are pivotally mounted to the suspension assembly and engageable with a coupling. The release arm pivots to a discharge position to discharge a single coupling while the keeper prevents rearward travel of further couplings. In the retainer position, the keeper permits rearward travel of coupling units to the release arm, and the release arm engages a single coupling and prevents its release.

Filed: 1996-09-04
Abstract: A process for producing a steel cord for pneumatic tyres with a bunch of wires, the core of which consists of wire filaments (10) arranged in a bunch parallel and adjacent to one another. There are advantageously at least three wire filaments (10, 20), where at least two wire filaments (10) are spirally wound as filaments (10) forming a core (60) and run parallel and beside each other and at least one wire filament is spirally wound around the two core filaments (10) as the wrapping wire (20). According to the invention, the spiral deformation of the wire filaments (10) is obtained by false twisters (40). This spiral deformation of the wire filaments (10) especially prevents migration of the filaments from the cord composite. It is an advantage if residual torsional stresses between the core filaments and in connection with the restoring forces of the wrapping wire are relieved. The steel cord also advantageously has a flattened, especially oval, shape.

Abstract: A Vehicle Acceleration and Attitude Sensor is provided, having use as a vehicle collision sensor for activation of air bags and the like, and as well for detecting within off road vehicles an unsafe attitude of the vehicle. A compressible carrier medium of light or other wave energy, such as translucent foam, is coupled with a light or other wave energy source and a receiver. An inertial mass, which may consist of the carrier medium itself, is in contact with the carrier medium and operates to compress the carrier medium when the apparatus is either accelerated or tilted beyond a predetermined amount. A signal coupler and processor are associated with the energy source and receiver. The apparatus operates on the principle whereby compression of a scattering medium or an integrating cavity, within the region surrounding a light or other wave energy source, will increase the intensity of the wave energy. This increased intensity is translated into a measurement of the acceleration or tilt experienced by the sensor.
