Abstract: The present invention relates to tool carriers usually used on work belts, aprons, bucket carriers and the like. The present invention comprises a tool carrier or bag that has at least one handle on the top thereof so that it can be carried from place to place in an upright position, either while it is still on a work belt that is not currently being worn or being carried by itself. In the preferred embodiment, a structurally strong handle is attached to the back of the tool carrier proximate the area in which a belt may be inserted through the tool carrier by heavy duty attachment means. It is preferable to use two tool carriers each having a handle through which the user's hand is inserted in order to provide even weight distribution when the belt is being carried from place to place.

Abstract: In a film projection system which contains a light source which emits a large amount of radiant energy and has means for advancing the film through a gate, there is a new and improved shutter comprising a high temperature rated, transmissive substrate having at least one area having a cold mirror coating affixed thereto and a second area with a hot mirror coating affixed thereto such that when the shutter rotates within the projector, the shutter area containing the cold mirror coating is placed in front of the light source when the film is moving through the gate and the shutter area containing the hot mirror coating is placed in front of the light source when the film is located within the gate, such that the thermal deformation of the film caused by the variations in the energy between the time the film is exposed and the time when the film is moving through the gate is minimized.
