Abstract: This disclosure relates to a wear button or pad for a telescoping boom of the type comprising at least an outer boom member comprising a threaded bore therethrough for the wear pad assembly, and an inner boom member that is slidable with respect to the outer boom member. In one form, the wear pad assembly comprises a wear pad and a base, a first of which comprises a generally cylindrical body comprising a curved external side surface comprising a screw thread via which this is threadably engageable in the threaded bore, and an internally tapered expandable collet, and the second of which comprises an externally and complementarily tapered mandrel portion, wherein in use, the externally threaded part is threadably engaged in the threaded bore and expanded therein by insertion of the externally and complementarily tapered mandrel portion in the expandable collet.

Abstract: An oxygen respirator is provided for emergency evacuations, which is simple to carry. The oxygen respirator increases the amount of air which a user can breathe by reusing the expirations of the user, such that the survival rate of the user is increased.

Abstract: Oxygen supply elevator which supplies oxygen to an internal space of the elevator or a separate oxygen mask provided in the elevator, thereby allowing a user to easily breathe and removing smoke or the like. The oxygen supply elevator includes: an oxygen containing unit which is provided in a facility mounting space formed on the elevator and contains oxygen at pressure higher than atmospheric pressure; an oxygen supply unit which is connected with the oxygen containing unit through at least one communication channel and supplies oxygen to an oxygen supply space in the elevator; a valve unit which is provided on the communication channel and adjusts a flow rate of oxygen discharged from the oxygen containing unit; and a control unit which is connected to the valve unit and adjusts whether to open or close the valve unit or an opening amount of the valve unit.

Abstract: Provided is a helmet-type personal disaster relief device which supplies fresh air to a wearer during an evacuation time period upon the occurrence of disasters, and protects the skin of the face, neck and shoulders of the wearer. For this purpose, the helmet-type personal disaster relief device of the present invention comprises a helmet body having an outer shell, an inner shell formed inside the outer shell, and an air storage space formed between the outer shell and the inner shell.

Abstract: There is provided a soft electrode material including an electrode layer containing a mixture of carbon black and at least one selected from carbon nanotube and graphene, so that the soft electrode material can facilitate various transformation thereof in response to physical transformation of an electrode, such as warpage, elongation, and the like; prevent the rapid reduction in electric conductivity of an electrode while maintaining flexibility and elasticity of the electrode at the time of the transformation; and provide excellent reliability, and thus, electrical-mechanical energy conversion efficiency of a soft electronic component such as an actuator including the soft electrode material, can be increased, and electric conductivity of the electrode layer can be improved as the electrical-mechanical conversion efficiency increases.
