Abstract: A package for a medical device such as an intermittent catheter has a case and a cap connected by threads. The case includes a hollow tube which is closed at one end and open at the other. A shoulder is formed near one end of the case. Above the shoulder is a cylindrical ferrule that includes external threads. The cap has internal threads selectably engageable with the threads on the ferrule to form a liquid-tight seal between the cap and case when the cap is installed on the case.

Abstract: A sound attenuation canopy for reducing levels of sound passing through an opening comprises a sound absorbing member. The member is comprised of a flexible sound absorbing material and has a first end, a second end and an intermediate portion extending therebetween. The first end is configured to attach to the opening's periphery at a first location, the second end is configured to attach to the periphery at a second location and the intermediate portion is configured to be spaced apart from the opening. When the first end and the second end are attached to the periphery of the opening, at least one side opening is at least partially defined by the intermediate portion and the perimeter of the opening, and a sound transmission flow path through open space between the opening and the side opening comprises at least one change of direction greater than 45 degrees.

Abstract: An exhaust gas recirculation system for an internal combustion engine including a valve body having an exhaust port adapted for fluid communication with a source of exhaust gas, an intake port adapted for fluid communication with the intake manifold of an internal combustion engine, and a valve member movably supported within the body between open and closed positions thereby controlling the flow of exhaust gas from the exhaust port to the intake port. A diaphragm housing is operatively mounted to the valve body and supported thereby. The diaphragm housing defines a vacuum cavity in fluid communication with a source of negative pressure and an atmosphere cavity in fluid communication with a source of second pressure. A diaphragm member is disposed between the vacuum and atmosphere cavities and is operatively connected to the valve member.

Abstract: There is provided an improved access and evacuation apparatus for an offshore platform, in which the apparatus comprises an articulated arm for rotatably mounting on an offshore platform. The arm comprises an inner part which has first and second ends and an outer part also having first and second ends. The first end of the inner part is adapted for rotatably mounting on the platform and the second end of the inner part is rotatably connected to the first end of the outer part. The arm is selectively moveable between an upper position in which the second end of the outer part is adjacent the platform, and a lower position in which the second end of the outer part is below the surface of the water and remote from the platform. There is also provided a winch and a cable operatively connecting the winch to the arm.

Abstract: There is provided a new and useful access and evacuation sytem for an offshore platform, the system comprising a rotating arm for mounting on the support structure of an offshore platform, the arm selectively moveable between an upper position in which an outer end of the arm is adjacent the platform, and a lower position in which the outer end of the arm is below water and remote from the platform; a pick-up adjacent the outer end of the arm for capturing and suspending a boat; a winch for selectively raising and lowering the arm; a boat; a suspension on the boat for mating with the pick-up; and shock absorbers on the suspension whereby to minimize shock to the boat when boat is being captured by the pick-up.

Abstract: A modulated electronic ballast for driving a gas discharge lamp includes a full wave rectifier for supplying a modulating signal to a series fed parallel resonant circuit including two transistors. Inductors are provided on both the hot and neutral alternating current power source lines for shielding the power source from electromagnetic interference and providing transient protection. A biasing circuit supplies a small direct current to the resonant circuit for retaining the resonant circuit in a continuous oscillating mode during substantially zero voltage valleys of the modulating signal. A diode is provided across the base and collectors of each transistor in the resonant circuit for preventing over saturation and co-conduction.

Abstract: A ballast circuit enclosure and grounding structure for electrically grounding a ballast circuit to a housing and for capturing transmitted RFI and EMI therefrom. The ballast circuit enclosure includes an elongate housing for receiving and surrounding the ballast circuit. End caps are attached to the housing opposite open ends in closing engagement with the housing. The end caps are fastened to the housing with fastening members extending through holes in the end caps and into elongate channels formed on the inside of the housing. The ballast circuit board rests on elongate abutment shoulders within the housing and is sandwiched between the abutment shoulders and longitudinal walls forming the elongate channels. A grounding wire on the edge of the circuit board is coupled to the ballast circuit and is in electrical contact with the fastening member and/or the channel forming elongate wall of the housing.

Abstract: A system for launching and retrieving boats from an offshore work platform, the system comprising a deployment arm adapted to be rotatably secured at one end thereof to superstructure of the platform for rotation between a first pre-launch position and a second post-launch position, means for controlling rotation of the arm between the first and second positions, and boat support means mounted adjacent an outer end of the arm, the support means comprising a spaced pair of support members each having thereon an open claw structure for receiving a support pin associated with a respective side of a boat.

Abstract: There is provided a new and useful offshore evacuation system for drilling rigs or platforms comprising a launch structure for a survival craft; the structure comprising at least one support strut adapted to be pivotally attached at one end thereof to the platform superstructure and carrying at the other end thereof at least one support cradle for survival craft, and rotatable between an upper position and a lower position; and means for effecting rotation of said launch structure from said upper to said lower position; and a closed companionway leading from the platform accommodation unit to the loading position of the survival craft and being in sealing relationship with the survival craft.
