Abstract: A prosthetic interface includes an orientation assembly, a mounting plate and a load bearing assembly. The orientation assembly includes an anterior frame portion and a posterior frame portion. The anterior frame portion extends over an anterior portion of a torso of a wearer of the prosthetic interface. The posterior frame portion extends over a posterior portion of the torso. The mounting plate is disposed at an intersection of the posterior frame portion and the anterior frame portion. The mounting plate forms a structure to which a prosthetic limb is attachable. The load bearing assembly includes breathable fabric forming a load distribution matrix to distribute a load on the mounting plate over portions of the torso with which the fabric is in contact.

Abstract: An impact resistant device is provided comprising a flexible support matrix and a plurality of energy absorbing elements operatively connected to the support matrix, each element comprising at least one ceramic material and at least one strain rate sensitive material. The impact resistant device can be worn as body armor to protect the wearer from high velocity projectiles.

Abstract: A shaving implement includes a handle fabricated from a soft, flexible and non-meltable material incapable of taking an edge or a point capable of penetrating human skin, and a frangible razor blade.

Abstract: A bone substitute for use in impact testing of a structure simulating the human body which includes a member fabricated from epoxy resin and having a lengthwise dimension, and a fiberglass sheath embedded in an outer circumferential portion of the member, the sheath having glass fibers oriented along the length of the member.

Abstract: A method of covertly detecting and reporting a distress condition in a control cabin of a vehicle, the cabin having designated areas expected to be occupied by respective operators under normal operating conditions of the vehicle. The method comprises (a) attaching to each operator a transponder tag configured to wirelessly transmit a response signal, unique to the operator to which it is attached, responsive to an interrogator signal; (b) wirelessly transmitting interrogator signals into the designated areas; (c) attempting to detect response signals, if any, from the transponder tags; and (d) if all of the response signals are concurrently not detected, then wirelessly transmitting a distress signal from the vehicle.

Abstract: A structure that includes a plurality of cells of a cured resinous material. Each cell is joined to at least one other cell.

Abstract: A pressurized fluid delivery system is disclosed. The system includes a container with an outer bag and an inner bag. The inner bag can contain a consumable fluid. The inner bag includes a fluid port capable of transferring the fluid through a tube and to a pendant that is designed to engage a mask connector. The outer bag can contain both the inner bag and a pressure space. Increasing pressure to the pressure space helps to squeeze fluid out of the inner bag and deliver the fluid to a user. The pendant can also include a gas port that can be used to deliver a gas to the user.

Abstract: There is provided a new and useful tram car wheel comprising a metallic hub section, a formed non-metallic wheel on the hub, a pair of cable flanges on the wheel, and an open reinforcing structure in the wheel anchored to the hub section.

Abstract: There is provided a new and useful tamping tool for a railway ballast tamping machine comprising: a shank comprising a shaft, means for fastening the shaft to a tamping machine, and, integral with the shaft, a foot including a first surface; a deformable stress equalizing pad; and a tamping pad adapted to be removably secured to the foot, the tamping pad having a cavity adapted to receive the foot therein, the cavity having a surface corresponding to the first surface of the foot and having at least one other surface corresponding to a second surface of the foot, the relative dimensions of the foot and the cavity being such that when the foot is inserted into the cavity with the equalizing pad between the first surface and the surface corresponding thereto, the at least one other surface is jammed against the second surface, and the equalizing pad is deformed in compression to a thickness which is less than its original thickness.

Abstract: A method of manufacturing metal parts containing an element which is attacked by lead comprising coating the metal parts with zirconium nitride by treatment with a zirconium-containing metal melt.

Abstract: A method of manufacturing a mixture of finely divided metals and solid perhalogenated carbon compounds, which mixture is capable of reaction when it is ignited, in which perhalogenated carbon compounds are used as solvents.
