Abstract: The present invention relates generally to dispensing system configured for dispensing a food product. The invention also relates to a peristaltic pump that has a pumping member configured to move along a path through a pumping position and a loading position. The pump also includes a motor in drivable association with the pumping member to move the pumping member along the path and a backing member having a surface configured to cooperate with the pumping member to pinch a conduit therebetween when the pumping member engages the conduit to establish peristaltic association in the pumping position to peristaltically pump a fluid therethrough. When the pumping member is in the loading position, the pumping member is disposed to allow the conduit to be received in and removed from a pumping space. The present invention also relates to a method for dispensing a food product using a peristaltic pump.

Abstract: The present invention relates generally to dispensing system configured for dispensing food product. The device includes a fluid container in fluid communication with a conduit having a compressible portion which is associable with a pumping mechanism for pumping a fluid therethrough. The compression portion contains an upstream uni-directional valve and a downstream uni-directional valve, so that when the compression portion is resiliently compressed, fluid is forced through the downstream valve, and upon decompression, fluid is drawn through the upstream valve. The present invention also relates to a method for dispensing a food product.

Abstract: Various exemplary embodiments are provided of wheeled shovels. In one exemplary embodiment, a wheeled shovel generally includes a wheel assembly having an axle and a wheel. The wheeled shovel also includes a frame having an upper portion and a lower portion. The frame may be disposed relative to the axle such that the axle is operable as a fulcrum about which the frame may pivot. A handle may be disposed at about the upper portion of the frame. A shovel blade may be disposed at about the lower portion of the frame. The wheel assembly, frame, handle, and shovel blade may be cooperatively configured so as to enable the wheeled shovel to throw a load of material generally upwardly and forwardly away from the shovel blade in response to a sufficient force applied to the handle for pivoting the frame relative to the axle with a recoil generated through the fulcrum at the axle.

Abstract: The present invention provides a projector having particular application for use in front projection composite photographic systems. In particular, the present invention relates to composite color photography, whether still, motion picture, or video in which foreground and background scenes are separately recorded and subsequently combined, using known "blue screen" or special background color techniques, to form a single image. The present invention includes a high pressure, short arc, mercury-xenon lamp in an optical system to produce a high intensity beam at wavelengths of either: 436 n.m. (blue); 545 n.m. (green); 589 n.m. (yellow) or 650+ n.m. (red). The selected color beam is then manipulated by optical elements into close correspondence to the viewing angle of a camera lens, and made coincident with the camera view by means of a beam splitter. Unwanted light is removed from the system through a "light trap" which traps and systematically absorbs incident light.
