Abstract: An implantable tissue marker device is provided to be placed in a soft tissue site through a surgical incision. The device can include a bioabsorbable body in the form of a spiral and defining a spheroid shape for the device, the spiral having a longitudinal axis, and turns of the spiral being spaced apart from each other in a direction along the longitudinal axis. A plurality of markers can be disposed on the body, the markers being visualizable by a radiographic imaging device. The turns of the spiral are sufficiently spaced apart to form gaps that allow soft tissue to infiltrate between the turns and to allow flexibility in the device along the longitudinal axis in the manner of a spring.

Abstract: A gravity operated shell feed apparatus for a turret-mounted gun comprises two stacks of downwardly sloping magazine racks, from the lower ends of which shell may be singly released to roll into an appropriately positioned collection tray which is then angularly deflected in a vertical plane so as to transfer the shell to a ramming tray for delivery to a ramming position at the gun, the whole sequence being manually controlled by means of a single operating lever.The apparatus is designed for a fixed loading position thereby avoiding the necessity of sweeping the feed apparatus at high speed through a large volume of turret space, and using instead the elevating gear of the gun to sweep the balanced elevating mass through a smaller turret volume at a proportionately lower speed, in a region less hazardous to the gun crew.
