Abstract: A spreader assembly may include a hopper configured for receiving a spreadable material, a removable cartridge configured for sliding engagement with the hopper and having a material transportation mechanism configured for receiving the spreadable material from the hopper, and a spreader configured for receiving the spreadable material from the material transportation mechanism and spreading the spreadable material onto a target surface. One of the hopper and the cartridge may include a roller having a roller surface, and the other of the hopper and the cartridge may include a bearing surface configured for rolling engagement with the roller surface. The cartridge may have one or more pull bars to facilitate removal of the cartridge from the hopper. Related methods are described.

Abstract: A portable exercise device is described. The device includes a collapsible chair and resistance cables selectively connected to the chair. The device can be manipulated between an extended configuration for performing exercises, and a collapsed configuration for transport or storage. The resistance cables are attached to the chair by being fed through or otherwise engaging apertures in the chair. The apertures may be defined by the chair frame members, holes extending through the frame members, brackets attached to the frame members, or channels near the frame members.

Abstract: A bed exercise device adapted to be mounted to a bed includes a rail with a plurality of openings there through by which exercise components can be mounted. First and second legs extend from opposite ends of the rail. The first and second legs attach at a first end of each of the first and second legs to the opposite ends of the rail and at a second end of each of the first and second legs to first and second brackets, respectively. The first and second brackets are adapted to attach to a frame of the bed. According to an alternative embodiment, a triangular frame is attached to the lower portion of the first and second legs to support an assembly of a rail, first and second arching portions, and first and second legs.

Abstract: A device for dispersing and dampening impact forces that includes a first sheet structure and a second sheet structure that are joined together at a boundary zone. The boundary zone joins the first sheet structure and the second sheet structure together to define at least one gas-tight chamber having two sides. A gas is contained within the gas-tight chamber at a pressure within a predetermined range of acceptable pressures for dispersing impact forces translated against one side of the device such that a blunt force trauma producing impact force is not transferred through the device to a wearer's body disposed proximal to the other side of the device.

Abstract: A volume analyzer is provided. The volume analyzer includes an input, a processor, and an output. The input is operable to receive market data and a calculation policy. The processor is coupled with the input. The processor is operable to identify an available implied pattern based on the market data and the calculation policy. The available implied pattern has not been calculated by a match engine. The output is coupled with the processor. The processor is operable to provide the available implied pattern to the output.

Abstract: A combination closure-cup assembly including a rotatably removable cup for securing to a bottle. The bottle having an inner cavity, frusto-conical neck and spout including external threading, and an annual peripheral flange extending outwardly from the frusto-conical neck below the external threading. The cup has a first end having a circular flat bottom including a scalloped rim, a second end, and a frusto-conical neck portion connecting the first and second end. The cup includes an outer surface, an internal cavity having threading, an inwardly recessed straw aperture, and a leak proof seal. The outer surface has a plurality of axial ribs.

Abstract: An indoor air purification system and method of same includes a case which removably attaches to an exhaust of cleaning equipment. An air purification chamber housed within the case includes an intake and exhaust wall and side walls, including a first side wall having an outside and inside surface. The intake and exhaust walls of the chamber are covered by aluminum metal mesh filters with a titanium dioxide coating. An ultraviolet-A blacklight blue is mounted to the inside surface of the first side wall of the chamber and includes an elongated u-shaped lamp for activating the titanium dioxide coating. An ultraviolet-C germicidal light for ultraviolet germicidal irradiation is mounted above the ultraviolet-A blacklight blue within the chamber and includes an elongated u-shaped lamp. A solid state high frequency electronic ballast powers and activates the lamps and converts voltage.

Abstract: The vertically reciprocable eject head at the finished article eject station of a molding machine has a row of cylindrical eject cores that project downwardly from the head during operation. From time-to-time, the eject cores must be replaced with a different set of cores having a different spacing and number. A universal mounting plate forming part of the quick change apparatus of the eject head has an elongated through slot extending longitudinally along the length of the universal plate that receives the eject cores but does not establish their position. One or more adaptor plates detachably fastened to the bottom side of the universal plate has a row of holes therein that register with the receiving slot of the mounting plate so as to establish the number and location of eject cores that can be carried by the eject head.
