Abstract: A device for distributing successive products of a product flow, particularly the successive folding products produced by a cross cutting device by dividing a material web, to two branch flows, with a wedge arrangement which is arranged in a stationary manner in the transporting plane of the product flow and which engages between two cam rollers which flank it and which are arranged symmetrically with respect to the center working plane. The device is characterized in that the wedge arrangement engages between two guide plates which flank it and which, together with the wedge arrangement, define a path fork. The guide plates have slots through which they are alternately penetrated by cams of the respective adjacent cam roller which are associated with the slots, so that the penetrating cams and the guide plate which is not penetrated form a feed for a belt guide associated with a branch flow.

The fine filter is configured open toward one side and is closed by a cover. The cover is formed integrally with a base plate sealing the casing of the swirl pot. As a result, the feed unit has a particularly low number of components to be assembled and can be produced in a particularly cost-effective way.

Abstract: An optical filter uses two or more reflective polarizers together with retarders to form birefringent filters with controlled transmission. The energy reflected by these polarizers is absorbed by one or more dichroic elements, which can be adjacent to a reflective polarizer; or spaced apart from it by one or more retarder elements. These dichroic elements act as dampers, so the energy of rays undergoing multiple reflections is markedly reduced or virtually eliminated, and high image quality is maintained. This provides a filter arrangement with enhanced spectral range, image quality, or greater extinction, or lower cost, compared to filters using dichroic or prism-type polarizers.

A pump handle is used to move a piston that draws the fluid from the fluid reservoir into the secondary fluid chamber before discharge. The pump handle is also used to selectively connect the trigger mechanism to the ratchet mechanism to allow incremental discharge of the fluid from the secondary fluid chamber. A handle is selectively connectable to the ratchet mechanism and configured to manually move the ratchet mechanism to a first position against the urgency of the spring. The handle is also selectably connectable to a pump mechanism, the handle being movable from a first position to a second position, wherein the handle is connected to the ratchet mechanism in the first position and connected to the pump mechanism in the second position.
