A flotation vest includes a back panel and two front panels joined to the lower sides of the back panel. Each front panel includes a lapel portion which extends upwardly to join the back panel at an upper corner. An armhole is defined between each front panel and the back panel, adjacent the respective lapel portion. Each front panel includes two layers of fabric defining between them a pocket which extends continuously through the front panel including the respective lapel portion. Flotation material is provided in each pocket, the flotation material including a plurality of independent sheets of buoyant, flexible material in each pocket below the respective lapel portion, and a single sheet of buoyant, flexible material in the respective lapel portion, the single sheet being folded to provide a plurality of juxtaposed layers connected at folds. In this manner, the folds prevent interleaving of the independent sheets with the folded single sheet.

Pivoting helmet mounts for an optical device are provided. In one aspect, a breakaway connector which is selectively configurable between breakaway and nonbreakaway configurations is provided. In a further aspect, a strap mount system for securing the helmet mount to the helmet employs a rotating ratchet assembly to adjust tension in the strap. In another aspect, a helmet mount for an optical device comprises a track assembly attached to a helmet to allow stowing of the optical device in a further retracted position. The track mount system may further include electrical connectors for attaching a power supply and an electronic device. In another aspect, a mounting bracket allows helmet-mounted optics to be shared with a weapon accessory mount. In a further aspect, a optical sighting device for a weapon combines a reflex sight a night vision goggle to allow targeting at night or in other low-light conditions.

A loader includes a sling for supporting a one or more items. The sling is secured on opposite sides of a loading chamber. The loader also includes a lowering mechanism. The lowering mechanism can lower the sling. The loader includes a release mechanism that secures one or both sides of the sling. After the sling is lowered by the lowering mechanism an adequate distance to place the one or more items close to the receptacle, the release mechanism releases one or both sides of the sling, which places the one or more items in or on a receptacle. The loader includes a take-up mechanism attached to one side of the sling. The take-up mechanism takes up the sling when the opposite side of the sling is released by the release mechanism. The loader is capable of inserting close fitting items into receptacles, such as a stack of trays of produce.

A tray-type container 10 includes a bottom wall 20, longitudinally-extending outer side walls 22, and laterally-extending end walls 24, the outer side walls 22 and the end walls 24 extending upwardly from the bottom wall 20 to form an inner cavity 26. As erected, the outer side walls 22 include a plurality of spaced-apart stacking tabs 28A-28D, and the bottom wall forms a plurality of spaced-apart apertures 60, 70, 80, 82, 86, and 88 for receiving the stacking tabs 28A-28D of like or similar containers. A plurality of tray-type containers 10 may be unitized in several stacked configurations utilizing the stacking tabs 28 and apertures 60, 70, 80, 82, 86, and 88. Typically, the plurality of unitized containers 10 are placed upon a shipping pallet or slip sheet, or placed within a shipping container to facilitate shipping by large carriers.

An apparatus and method for uniformly and rapidly stacking one or more comestible portions provided on carrier sheets is described. Such carrier sheets are often used as a separator sheet after stacking. In the apparatus of the invention, linear slide platform fingers intermesh with an o-ring acceleration conveyor. The comestible portion and carrier sheet are delivered onto the intermeshed fingers while constantly being driven forward by the acceleration conveyor. As the linear slide pulls the fingers away from the acceleration conveyor, it accelerates rapidly and causes the comestible portion and carrier sheet to engage separator bars which cause the comestible portion and carrier sheet to fall into a uniform stack.
