  • Needle assembly
    Patent number: 4530697
    Abstract: There is disclosed a needle assembly comprising a needle, a needle-retaining portion, a removable needle protector portion, and a resilient member for removing liquid from the surface of the needle which is disposed around the needle rearward of its point. The liquid removing member has a needle-accommodating opening with a diameter approximately that of the outside diameter of the needle. The member is contained within the needle protector portion and removable from the needle with the removal of the needle protector portion from the assembly. Also disclosed are blood bag systems comprising a donor bag and the aforementioned needle assembly.

  • Apparatus for copy machining having a manual control
    Patent number: 4170850
    Abstract: Apparatus for copy machining provided with two motor driven carriage saddles, and with a steering disc, the latter being connected to sliding contacts of two potentiometers having several tappings through a control disc and a transmission mechanism. The potentiometers are divided in four equal parts by five tappings. In each potentiometer the first, middle and the last tapping are connected to each other, and the remaining two are also connected.The potentiometers occupy a phase position complying with the angular displacement of the steering disc, whereas the terminals are connected to the motors. The potentiometers determine the ratio of the revolution numbers of the motors to each other, i.e. the direction of tool movement. A third potentiometer controls the speed of the tool movement.
