Special inflatable bags are provided between the liner and the container at positions where cargo tends to remain during unloading of the liner.  Fluidizing means and agitation means are also provided to enhance the unloading of the cargo. In another embodiment, there is disclosed a novel modular bulkhead configuration that has an interlocking internal construction.

Title: Cable as suspension means for lifts
Inventor: DE ANGELIS CLAUDIO
IPC: D07B1/16
Filed: 1995-02-08
Granted: 2001-04-10
Abstract: This cable (1) has suspension means for lifts, which is connected with a cage (13) or load-receiving means, consists of synthetic fibres. A sheathing (2) surrounds an outermost strand layer (3). The sheathing (2) consists of synthetic material, preferably of polyurethane. Strands (4) are twisted or laid of individual aramide fibres (5). Each individual strand (4) is treated with an impregnating medium for the protection of the fibres (5). A friction-reducing intermediate sheathing (7) is arranged between the outermost strand layer (3) and the inner strand layer (6). In order to obtain and almost circularly shaped strand layer (6) and increase the degree of filling, gaps are augmented by filler strands (9). The task of the sheathing (2) consists in assuring the desired co-efficient of friction to the drive pulley and to protect the strands against mechanical and chemical damages and ultraviolet rays. The load is in that case carried exclusively by the strands (4). The cable (1) built up of aramide fibres (5) by comparison with a steel cable displays a substantially higher carrying capacity and only one fifth to one sixth of the specific weight for the same cross-section.

Abstract: A closure device for use with a container (11) having an open neck finish, including an inner cap (21) having a skirt (27) terminating in an open end which engages the outside diameter (D1) of the finish. The inner cap (21) is sized to initially engage the finish. The skirt (27) has circumferentially spaced slits (33) extending, which may function as lyophilization ports, which permit the inner cap (21) to expand upon an axial closing force and engage the bottom of the finish. A liner (19) is positioned in the inner cap (21) proximate the closed end and is compressed against the finish when the cap is moved to alignment with the bottom of the finish. An outer cap (17) is locked on to the inner cap (21) in pre-assembly which then encloses the inner cap (21) after complete assembly to seal and compress the liner (19) between the finish (43) and the inside face of the inner cap (21). In a preferred embodiment, an inwardly facing ridge (35) is located on the inside of the inner cap (21) to engage the liner (19) by a distance sufficient to permit the liner (19) to seal to the finish (43) over the maximum variation of dimensions for the liner (19) and for the crown on the finish (43).

A set of aircraft survivability sensors (12, 32, 34, 36) provides a threat sensor data fusion control process (302) with status data (304). The control process controls (302) whether or not a threat ambiguity detector (308) receives radar warning receiver data (42) or a radar emitter ID conversion apparatus (310) receives pulsed radar jammer data (38) or continuous wave radar jammer data (46). The threat sensor data fusion control process (302) also determines whether missile approach detector data (48) is sent to a countermeasures analyzing apparatus (326). The threat ambiguity detector (308) provides ambiguity data (340) to a threat ambiguity resolving apparatus (324). The radar emitter ID conversion apparatus (310) provides converted jammer data (342) to a functional sensor back-up apparatus (201). The radar emitter ID conversion process (310) receives a common radar emitter (ID) data base (312). The threat sensor data fusion process controller (302) also provides fusion process control (338) to the complementary threat data apparatus (322). Complementary threat data (332) is provided to the pilot through various presentation methods and to the jammers (34, 36) for electronic countermeasures. Also, threat ambiguity resolution data (334) is provided and back-up data (228, 230) is provided. The presentation methods include video (224) and voice (226) and a tactical electronics countermeasures command (330) is automatically initiated. A multi-pass sensor data correlation algorithm (328) and a threat prioritization algorithm (252) share information with the threat ambiguity resolving algorithm (324), complementary threat data algorithm (322), functional sensor back-up apparatus (201), and electronic countermeasures apparatus (326). The direction of jamming is determined by data correlation between the radar warning receiver (12) and the CW Jammer (34).
