Abstract: A refuse collection vehicle has a lifting apparatus for lifting a refuse storage container onto and off the vehicle's flat bed body. The lifting apparatus employs a pulley apparatus including a plurality of pulleys and a pulley carrier that is moved reciprocally by a single fluid actuated cylinder. A pulley cable is connected to the pulleys in a predetermined manner to apply to the pulley carrier substantially equal forces so the carrier avoids twisting laterally as it moves reciprocally.

Abstract: A dual-chamber syringe has a plunger within an inner delivery chamber in fluid communication with an ejection port. The deliver chamber is formed within a tubular element axially slidable within a tubular guide. The tubular guide and the syringe outer barrel form an outer reservoir chamber. The outer reservoir chamber is sealed from the delivery chamber while the tubular element is in a first position within the guide. Upon withdrawal of the plunger, frictional contact imparted by the plunger seal causes the tubular element to slide away from sealing engagement with the barrel into a second position within the guide. In the second position of the tubular element, a fluid passageway is opened from the reservoir to the delivery chamber allowing fluid to be drawn into the delivery chamber. A porous seal between the plunger rod and barrel allows air into the reservoir during transfer of fluid to the delivery chamber.

Abstract: An instrument provides a quantitative measurement of an analyte in a gas. It includes a detection cell that provides an indication of an amount of analyte present in the gas, and a valve having a closed position, a sample gas position, and a calibration gas position. There is a calibration gas inlet orifice in communication with a gas outlet through a first flow path including the valve and the detection cell, and a sample gas inlet orifice in communication with the gas outlet through a second flow path including a scrubber, the valve, and the detection cell. Two orifices of different sizes, a sample gas orifice along the second flow path, and a bypass orifice positioned between the sample gas orifice and the gas outlet, prevent a build up of excessive pressure in the instrument when the valve is in the closed position or the calibration gas position.

Preferably, the guard section of this tool is transparent, and it has indicia thereon which assist in aligning the tool with the implanted medical device. The guard section may include a depression on its underside which overlies the implanted medical device when the guard is placed in position for accessing or deaccessing the needle.

Abstract: A fountain includes a container having a top with an opening therein, a bottom, and an interior for holding a liquid, such as water. An elongated, hollow support member is positioned within the interior and extending from the opening in the top. This support member has a first end mounted at or near the bottom of the container, a second end terminating a predetermined distance above the opening in the top, and an exterior surface over which liquid flows. A pump positioned within the interior and operably connected to the first end of the support member pumps liquid in the interior into and through the hollow support member to flow out its second end and then along the exterior surface of the support member to return to the interior of the container. A faucet is attached to the second end of the support member in a manner which allows the liquid to flow from the second end.

Abstract: A unitary removable barrier for installation in a cylindrical water line to selectively block the water line to passage of water therethrough. The unitary removable barrier is composed of a single piece body having at least one cylindrical section sized to receive upstream and downstream pipes of the water line. A planar disk is molded with the cylindrical section and is of a circular circumference which completely blocks the water line but which is selectively removable from the cylindrical section thus removing the barrier to the passage of water through the line. Removal of the barrier is facilitated through the use of a piercing device and pull tab which can be actuated from a position outside of the waste line.

Abstract: A utility bar is disclosed comprising a bowed shank, a lever piece and a junction that couples the shank to the lever piece. A chisel may also be coupled to the bowed shank.

Abstract: An ophthalmological device for cutting into a nucleus of a cataract comprises a phaco tip including a body having at a distal end thereof a solid blade with a face edge adapted to be placed in contact with the nucleus. There is no aspiration port in this face edge. An aspiration port in the body is displaced rearward from the face edge by a distance which is greater than the length of the blade. A sleeve fits over the body and has a forward section that terminates in an opening in advance of the aspiration port. The device is used alternately with a standard phaco tip to remove cataracts. A surgical instrument comprises a handpiece including phaco tip having a face edge having aspiration port therein that is adapted to be placed in communication with a source of aspiration. A control unit regulates the application of aspiration to the aspiration port, enabling aspiration at the aspiration port to be discontinued on command.

Abstract: A unitary removable barrier for installation in a cylindrical water line to selectively block the water line to passage of water therethrough. The unitary removable barrier is composed of a single piece rubber body having at least one cylindrical section sized to receive upstream and downstream pipes of the water line. A unitary rubber planar disc molded with the cylindrical section is of a circular circumference and which completely blocks the water line but which is selectively removable from the cylindrical section thus removing the barrier to the passage of the water through the line.

Abstract: A pressure sensing device adapted to measure pressure of a fluid includes a body member made of an inert material that does not react chemically with the fluid. A thin wall diaphragm section integral with the body member carries on its exterior surface a sensor that provides a signal proportionate to the pressure of the fluid within body member. The sensor device has an exterior surface with a bridge resistor circuit mounted thereon. The cross-sectional configurations of the sensor device and the thin wall diaphragm section are complimentary so their mating surfaces fit snugly together. A liner member made of an inert material that does not react chemically with the fluid fits within the body member adjacent the first thin wall diaphragm section and includes a second thin wall diaphragm section integral with the liner member.
