Abstract: A print medium transport path for a printing device transports a sheet of print medium that is charged to facilitate receipt of charged toner forming an image to be printed. The transport path includes a transfer roller for transferring said image to said print medium, a pressing roller for pressing said print medium after receipt of said image and a number of ribs running between said transfer roller and said pressing roller. The ribs are substantially parallel and spaced from each other to define the transport path.

Abstract: A flow sensor using induction pickup and having an improved paddle wheel type impeller within an impeller housing having a concave opening defining a protective skirt area for shielding a portion of the paddle wheel and a stem of the paddle wheel with a varying thickness for reducing cavitational backflow and therefore achieving a precise measurement of the fluid flow velocity and a high turndown ratio is disclosed.

Abstract: An umbrella includes a hollow tubular handle, a hub slidably contained in the handle between an upper extended position and a lower stored position; a spider hinge mounted on the hub and including radially extending spider arms; a plurality of flexible struts, each having a fixed end and a free end, with each strut having a width which tapers from the fixed end to the fre end and with the fixed end being secured on each spider arm; a retainer bushing and plug which fixedly secures the spider hinge onto the hub; each strut further having a block thereon with an outwardly radially extending opening; a cord extending peripherally about the umbrella and connected within the openings of the blocks and thereby to the struts for applying a pre-loading tensioning force to the struts so as to bend the struts into a bowed configuration; and a one-piece web of flexible, water-resistant material connected to the ends of the tensioned struts.

Abstract: A timer controlled container inverting apparatus is constructed and arranged to commence timing out for container inversion only after setting of proper inversion time and reception of the container in the apparatus e.g. a vial containing a contact lens in sterilizing solution and oriented for sterilizing process commences process timing only upon application of the vial to the timing apparatus. Shortening of proper sterilizing time is prevented and inversion is effected rapidly at completion of the sterilizing process.

Abstract: A two piece contact lens mold having a pair of blunt, continuous mating surfaces extending around the periphery of the mold cavity is disclosed. Location of the mold parting line tangent to the lens edge substantially eliminates registration problems when a relief groove is provided at the edge of the female member. Parameters for mold materials and important dimensions are also disclosed. The mold can produce finished contact lenses which do not require further machining.
