Abstract: A syringe configured with a limited maximum usable capacity. The syringe of the invention desirably has a retractable needle to prevent reuse. In the preferred embodiment, a dose-limiting structure includes a stop-ring member on the head of the plunger that abuts a constriction in the housing when the plunger is moved away from the needle to prevent the further rearward movement of the plunger. Preferably, the syringe of the invention is configured such that a user is tactilely signaled when the plunger has reached a position corresponding to a nominal fixed-dose. If the user attempts to force the stop-ring member beyond the constriction, the plunger seal is stripped off or removed from the plunger head and the syringe rendered inoperable. The features of the invention can also be applied to a nonretracting syringe.

Abstract: A fixture for suspending banners, signs and the like on the sides of multistory buildings, includes a U-shaped bracket adapted to engage the sides and end of a vertical parapet or a horizontal overhang. The fixture supports a powered winch over which cables connected to the banner or the like are arranged so as to allow the raising and lowering of the banner by powering the winch. Clamps on the U-shaped brackets securely retain the fixture in position on the building.

Abstract: A method is disclosed for altering in the field the operating instructions used by an industrial process transmitter to collect, manipulate and transmit output signals representing the state of an industrial process. The method is used with an industrial process transmitter that includes at least one alterable storage device that has a first set of operating instructions stored therein. A controller device is connected to the alterable storage device and a configuration device is connectable to the industrial process transmitter via a communication link. The method includes entering a user-defined second set of operating instructions in the configurations device and then translating the second set of operating instructions into a format readable by the controller device. A communications link between the configuration and controller device is next established.

Abstract: An integral hydraulic valve and cylinder assembly for power steering a marine drive. The assembly is operatively connected between the propulsion unit and the steering wheel of a boat and includes a common valve body for housing both the cylinder and the valve. A valve spool located within a spool-receiving bore formed in the valve body is axially slidable therein in response to movement of the steering wheel between neutral and operational positions for selectively establishing fluid communication of an inlet port with outlet ports and work passages in the valve body leading to the cylinder. A core wire is connected to the steering arm of the propulsion unit and is axially slidable within an internal bore in the valve body. In response to valve spool movement, hydraulic assistance is properly directed to aid in steering the boat.
