Inventor: JOHNSON CALDWELL C
IPC: B64G1/64
Filed: 1990-10-30
Abstract: A method and apparatus for joining vehicles such as spacecraft is disclosed that utilizes a capture and berthing technique. The coup-ling apparatus comprises a first coupling unit (12) having a general-ly rigid extensible structure (34) that is mountable to a first spacecraft (14) and a second coupling unit (16) having a probe-like structure (80) mountable to a second spacecraft (18) which is cooperable with the extensible structure (34) to effect ve-hicle coupling. The first and second spacecraft are maneuvered so as to generally align the coupling appara-tus thereon, after which the extensi-ble structure (34) is extended to en-gage and capture the probe-like structure (80). Following capture of the second coupling unity by the ex-tensible structure (34), the extensi-ble structure (34) is subsequently re-tracted to effect berthing of the first and second spacecraft. Once the spacecraft coupling units have been captured and berthed in the forego-ing manner, they can be structurally joined by appropriate coupling apparatus.

Patent CA-2072144-A1 (CA)
Inventor: JOHNSON RICHARD P
IPC: C05F17/02
Filed: 1990-05-18
Abstract: 2072144 9106517 PCTABS00005 A method and apparatus is disclosed for composting of organic matter. A ram advances the entire mass of organic matter within the composting chamber to create an evacuated space in the composting chamber, which evacuated space is of substantially greater volume than the volume of an incremental inlet space. The incremental inlet space is a space in the composting chamber defined by a projection of an inlet opening into the composting chamber. After the creation of the evacuated space, a new charge of organic matter is fed through the inlet opening. The ram then moves this new charge of organic matter into the evacuated space in the chamber to join the existing mass of organic matter already in the chamber.  The ram also lightly compresses the new charge to a predetermined density or porosity. Typically, the extent of compressive force applied to the new charge is less than that required to move the entire mass of organic matter through the chamber. In this way, the new charge remains sufficiently porous and uncompacted so as to facilitate drying with air which is circulated through the chamber. Once the new charge is sufficiently dry, the entire mass of organic matter may then be moved by the ram to create a new evacuated space in the chamber.
