Abstract: A rotational output assembly is configured to provide power to a drive assembly to cause pumping by a pump. The rotational output assembly includes an electric motor and a pinion drive projecting axially from the motor. The pinion drive interfaces with bearings supported on a pump frame. The pinion drive includes a gear teeth section between portions interfacing with the bearings supported on the pump frame. The gear teeth section interfaces with a drive gear of the drive assembly to cause rotation of the drive gear.

Abstract: A material sprayer includes a hopper and a shaker assembly mounted onto a sidewall of the hopper. The hopper includes at least one sidewall that extends along a first plane. The shaker assembly includes a resilient bracket, an electromagnetic coil, and an armature. The resilient bracket is mounted to the sidewall of the hopper and includes first and second ends and a curved portion. The electromagnetic coil is mounted to a portion of the resilient bracket and is configured to generate a magnetic field in response to a current from a power source. The armature is mounted to a portion of the resilient bracket such that the armature is able to move relative to the electromagnetic coil along an acceleration axis that is orthogonal to the first plane of the sidewall of the hopper.

Abstract: A pump for use with a material sprayer includes a cylinder, a piston, a pump head, first and second check valves, and an elbow connected to the cylinder. The cylinder and the piston are coaxial with a pump axis. The pump head is configured to make a mechanical connection with the reciprocating drive mechanism so as to allow the reciprocating drive mechanism to reciprocate the piston along the pump axis. The elbow includes a first end, a second end, and an inner fluid channel. The first end is configured to make a fluid connection with the hopper. The second end is configured to be fixed with respect to the cylinder. The inner fluid channel extends from the first end to the second end. The pump head and the first end of the elbow are configured to make mechanical and fluid connections with a single linear motion of the pump.

Abstract: A transducer, generally 10, has a robust, yet very flexible, steel-braid reinforced protective cover 12 which is permanently assembled to a custom machined fitting 14. A typical pressure transducer 16 is threaded through a SST nut 18 and then through the cover 12. Bonding the transducer body to the cover's fitting 14 captures the nut 18 between a flange 16A on the transducer 16 and a shoulder 18A in the nut 18, allowing the nut 18 to be freespinning yet a permanent part of the assembly 10.

Abstract: The seal (10) for a spray gun (20) is tubular in form and molded from an elastomer. The seal is placed in compression between two generally parallel surfaces (12) so as to seal out the fluid (such as paint) from the rod (14). As the trigger (16) is pulled and the rod (14) moved rearward, the seal (10) bulges to accommodate the travel without exposing the rod (14) to the fluid.

Abstract: A single sprayer 12 is allowed to run in two completely different operating modes, thereby becoming suitable for medias controlled best by either system pressure or by flow rate. This provides the user with the ability to apply a wider range of products without incurring the higher cost of two separate systems.

Abstract: A common method of retaining spray nozzles in texture applicators is to capture the nozzle by a rubber cap which is stretched over a retaining flange on the applicator's sprayhead. The effort required to stretch an elastomeric nozzle retainer (cap) 10 over the retaining flanges 12 on the sprayhead 14 is reduced by providing features facilitating the use of a prying tool 16 to amplify the user's effort. Flange relief flats 18 accommodate the natural, temporary inward deflection of the cap 10 during installation.

Abstract: Systems and methods are provided for the accurate, ongoing filling of prescriptions for disposable contact lenses. In a preferred system, a central ordering/inventory computer is associated with satellite PCs at which attending eye care professionals can place orders. In preferred methods, periodic serial to batcxh mode conversions merge new orders, standing orders, order changes, as well as other updates and deletions. Patient history files allow maintenance of data bases for the eye care professionals as well as for the manufacturer of lenses.
