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.

Title: Process for producing mixed refrigerants
Inventor: HAGA TOSHIO
IPC: C09K5/04
Filed: 1998-01-14
Granted: 2006-12-12
Abstract: A process for producing mixed refrigerants comprises selecting the order of introduction of refrigerant components (groups) so that the liquid density of the refrigerant component (group) to be introduced afterwards is lower at the introduction temperature than the density of the liquid phase of the refrigerant component (group) already introduced into the vessel, or for specific 3-component systems, introducing the first 2 components in descending order of density and selecting the vapor pressure of the final component so as to be higher than the vapor pressure of liquid phase of the component group already introduced into the vessel, with the refrigerant component to be introduced afterwards being introduced into the liquid phase of the already introduced refrigerant component (group). It is thus possible to rapidly and efficiently produce mixed refrigerants with uniform compositions by a simple admixture of different types of refrigerant components in a tank or steel cylinder.
