  • Patent number: 8052009
    Abstract: A bandage dispensing device dispenses bandages with an upper protective layer of its packaging removed so that a person can dispense a bandage using only one hand. A separator placed near an opening in a wall of the housing of the device separates the upper protective layer from a roll of interconnected bandages so that only a bandage and a lower protective layer emerge from the housing of the device. The separator has at least one arm that protrudes from the side wall of the housing in a perpendicular direction and separates an upper protective layer of the packaging. The upper protective layer that has been separated by the separator gathers inside of the housing. In the roll of packaged bandages, the upper protective layer is releasably attached to the lower protective layer.

  • Patent number: 7384050
    Abstract: An oxygen cart comprises a post connected to a handle and a bracket, a plurality of wheels connected to an underside of the bracket, at least one tank holder connected to an upper side of the bracket for holding portable gas tanks, and a tank support wall connected to and extending up from the tank holder said tank support wall keeping a gas tank in the holder when the cart is moving. There is a cart support surface connected to a lower end of the tank support wall for stabilizing the cart in an upright position when the cart is not moving. In order to accommodate several sizes of tanks, the tank holder has an upper section and a lower section, the upper section having diameter larger than the lower section, such that the upper section accommodates one size gas tank, and the lower section accommodates a different, smaller size gas tank. To accommodate an even smaller tank, a ring having an inner circumference that is smaller than a circumference of the lower section is used.

  • Patent number: 4433613
    Abstract: A power steering system for motor vehicles, wherein a steering nut, connected to a steering worm in such a manner that the steering worm is driven thereby, is rotatably and axially non-displacably mounted in a working piston and is also provided with a control arm passing through both a radial recess in a working piston and a radial opening in a cylinder housing that receives the working piston. An end of the control arm which is radially outermost with respect to an axis of the piston actuates a spool valve for adjusting the working pressure. Two corresponding followers are provided for defining the end stroke positions of the working piston. The followers are mutually engagable to lower or shut off a working pressure in the system. One of the followers is disposed opposite the working piston relative to the piston axis and the other is located opposite the cylinder housing relative to the cylinder axis with a zero motion.
