Abstract: ABSTRACT       An emergency warning traffic sign comprises a conventional stop sign which has been divided vertically in the middle into two sheet portions carrying portions of the message on one face of each of the sheet portions.  The sheet portions are connected by a hinge such that a first of the portions may be mounted to a traffic signal post and the second sheet portion may be rotated between a first position in which the message is obscured to a second open message position.  A locking bar is attached to the first sheet portion and is pivotally movable across the back of the sign and within its perimeter to lock the sign in both its open and closed positions.  In a second embodiment of the inven-tion, another sign carrying a different message is also divided vertically into a third and forth sheet portions and these sheet portions are hingedly connected to each other.  The third sheet portion is stationarily mounted to the back of the second sheet portion such that the second sign with its message may be displayed when the first sign is folded and vice versa.

Abstract: APPARATUS AND METHOD FOR HEATING       AN AGGREGATE MATERIAL                      Abstract of the Disclosure Relatively coarse aggregate is preheated to a relatively high temperature prior to introduction into a rotary kiln (12) by directing the aggregate downwardly along a predetermined path of travel while maintaining the aggregate in the form of a relatively thin layer and while directing the waste heated gases from the kiln (12) upwardly along a predetermined sinuous path of travel repeatedly passing laterally back and forth through the downwardly moving layer of aggregate from opposite sides thereof to thus provide highly effective contact of the gas with the aggregate, and while supplementally heating the waste heated gases so as to preheat the aggregate to a higher degree.  The thin layer of aggregate is guided downwardly through the preheater housing along a passage-way (35) formed by a pair of gas permeable retaining walls (36) which extend generally vertically in opposing spaced relation to one another, and which are of a nonlinear zig-zag configuration so arranged as to direct the thin layer of aggregate along a sinuous path of travel in the course of its downward movement along the elongate passageway (35).  The supplmental heating preferably is effected by a fuel burner (30) located in the lower portion of the pre-heater housing (31) in the path of the incoming waste heated gases which are received from the kiln (12) for further heating the gases prior to the gases being directed upwardly and into contact with the aggregate.

Abstract: APPARATUS FOR SEPARATING DUST, DIRT AND   THE LIKE FROM PARTICULATE MATERIAL                 Abstract of the Disclosure An apparatus for separating dust, dirt and the like from particulate material utilizes a flow of carrier fluid which passes through the particulate material on a grid or screen.  The heavier particulate material falls through the grid while the lighter material as well as the dust, dirt and the like are entrained in the fluid and carried upwardly.  A portion of the entrained material precipitates out of the carrier fluid into a vertical collecting bin whereupon it is discharged into another flow of carrier fluid.  A sensor within the collecting bin senses the level of the collected precipitated material and reduces the velocity of the carrier fluid when the material in the collecting bin exceeds a predetermined level.

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention contemplates effective printing of alphanumerical characters and symbols (for instance control points, sheet corners, terrain coordinates, place and field names, or the like), using optical projection of the characters or symbols onto the film which also receives the orthographic reconstruction of a scanned axial photograph.       Specifically, a master stencil of characters and symbols is arranged in the ray path of the optical system used for the orthoprojection, and the stencil is sequentially displaced and exposed while the orthophoto is still in the mapping apparatus.  The selection of stencil position is effected under computer control, such that after keyboard input of the desired character, the picture-supporting carriage with the stencil mounted thereon travels from one to its next position, with the projection system effectively shut off.  The size and orientation of character exposure can be preselected by element displacement within the orthoprojection system, which contains, inter alia, a zoom system and an image-rotating prism.

Abstract: Abstract of the Disclosure An ink jet printer is provided which will print in both the left to right and right to left directions of ink jet head travel with respect to the print media.  Relative horizontal displacement of ink jet droplets caused by horizontal travel of the ink jet head is compensated for by a deflection plate system which is tilted with respect to the direction of travel to provide an electric field which tilts the pattern of ink jet droplets in an equal and opposite amount from that caused by horizontal movement of the ink jet head. In one direction of travel an ascending pattern of ink jet droplets is provided and in the other direction of travel a descending pattern of ink jet droplets is provided for printing so that the tilted deflection plate system compensates appropriately for the particular direction of travel.

Abstract: ABSTRACT    Control is provided over the casting of iron pipe in a centrifugal casting machine.  The initial flow of molten iron from the pouring ladle into the trough actuates an electric eye.  A second electric eye is actuated when the molten iron has flowed to the end of the trough.  The centrifugal casting machine is rolled up to surround the trough, the bell end of the pipe to be formed being at the end of the trough.  A computer is utilized to determine the velocity of the iron on a real time basis.  This iron flow information is analyzed to calculate the bell flag time by a previously determined algorithm which takes into account the casting machine and the pipe size being cast.  The bell flag time is the time in which the molten iron is allowed to flow into the bell section of the pipe being cast, before the casting machine is moved away from the trough end to form the rest of the pipe.

Abstract: A HINGED HATCH ROOF ASSEMBLY FOR A VEHICLE CAB   Abstract of the Disclosure A hinged hatch assembly for the roof of a vehicle cab having an opening formed therein.  The assembly includes a hatch which completely covers the opening when in a closed position.  The hatch is connected to the roof of the vehicle cab by a pair of support arms.  Each support arm contains a first and a second forked end whereby the first forked ends are pivotally attached by brackets to one side of the roof opening and the second forked ends are pivotally attached by brackets to the underside of the hatch.  Sandwiched on each side of the brackets between the forked ends of the support arms are frictional elements which are spring loaded to impart a predetermined frictional force on the members.  The frictional contact permits the hatch to be opened at various angles and at various positions relative to the plane of the roof and to remain in the desired position irrespective of any vibration or motion imparted into the vehicle.  The hinged hatch roof assembly is capable of providing ventilation as well as serving as an escape route from the interior of the vehicle cab.
