Abstract: An on-tank valve for fitting to a tank to supply stored gas to a consumer and the tank to be replenished with gas from a filling station. The valve has a valve body defining at least two flow passages in communication with the tank. A first flow passage incorporates a solenoid valve to control the flow of gas from the tank to the consumer and the second incorporates a manually operable bleed valve for stored gas to be supplied to the consumer while bypassing the solenoid valve. The bleed valve is a combination valve movable manually between two states. In the first state stored gas is permitted to flow from the tank to the consumer and in the second state the second passage incorporates a non-return valve to permit the tank to be replenished from the filling station without the replenishment gas passing through the solenoid valve.

Abstract: A yoke-type phaser is disclosed having a drive member and a driven member rotatable about a common axis and coupled to one another by means of a yoke that is movable, in a plane normal to the common axis, to vary the relative phase of the drive and driven members, by interaction between at least two contact elements and a contoured surface, one of (i) the contact elements and (ii) the contoured surface being connected for rotation with the drive member and the other being mounted on the yoke, each contact element comprising a roller in surface contact with a part-cylindrical recess in a carrier, wherein the carrier of at least one of the contact elements is either appropriately sized or adjustably mounted, to set the clearances between the rollers and the contoured surface.

Abstract: The present disclosure relates to holders for protecting intraocular lenses and methods of use. The holder includes a posterior wall and an annular wall extending anteriorly from the posterior wall and having an anterior edge. An internal space is defined by the posterior wall and the annular wall. The internal space is sized to receive a lens body of the intraocular lens. The holder also includes a locking feature configured to secure the intraocular lens. At least a portion of the locking feature is anterior to the intraocular lens when positioned in the holder.

Abstract: Intraocular implants and methods of making intraocular implants are disclosed. The intraocular implant can include a mask adapted to increase depth of focus. The method of manufacturing the implant can include filling an annular mask-forming trough with an opaque mask material and adding an optically transmissive optic material over the opaque mask material.

Abstract: An intraocular lens is provided that includes a refractive element and a mask. The refractive element has a first power in a first meridian and a second power greater than the first power in a second meridian. A magnitude of the first and second powers and a location of the first and second meridians are configured to correct astigmatism in a human eye. The mask is configured to block a substantial portion of light from passing through an annular region thereof and to permit a substantial portion of light to pass through a central aperture thereof to enhance an astigmatism correction rotational misplacement range and depth of focus.

Abstract: Intraocular implants and methods of making intraocular implants are provided. The intraocular implant can include a lens body having a lens material and a mask having a mask material. The lens body can be secured to the mask. The mask material can include a modulus of elasticity that is greater than or equal to a modulus of elasticity of the lens material.

Abstract: Intraocular implants and methods of forming intraocular implants are described herein. The intraocular implant can include a powered optic and a lens holder. The optic can be mechanically coupled to an inner periphery of the lens holder to form the intraocular implant. A portion of the lens holder can include a mask disposed about the optic to increase depth of focus in a human patient.

Abstract: A summation rocker system is disclosed for acting on the end of a stem of a poppet valve (16) in dependence upon the combined lifts of a first and a second cam profile defined by different cam lobes (14, 22) of a concentric camshaft (46). The system comprises a first rocker (12) mounted on a pivot shaft (18) and having a first follower (44) to contact the first cam profile and an end acting on the valve (16) to displace the valve (16) by an amount dependent upon the lift of the first cam profile, a rocker shaft (24) to be fixedly mounted on the engine, and a second rocker (20) pivotable about the rocker shaft (24), the second rocker (20) having a second follower (48) to contact the second cam profile and acting to displace the pivot shaft (18) of the first rocker (12) in dependence of the lift of second cam profile.
