Abstract: A method and apparatus to ink and dampen a lithographic printing plate including a dampening fluid removal device comprising a doctor blade positioned in pressure indented relation with a resilient inking roller to remove dampening fluid of low viscosity from the roller while leaving more viscous ink on the roller surface. The blade, therefore, is efficient to doctor dampening fluid while insufficient for printing ink.

Abstract: A control means for a solar energy collector-concentrator of the focusing trough reflector type with an energy receiver operatively positioned at the line of focus of said reflector comprising pivotally mounted support means for said energy receiver held in a receiver-operative position by linkage including a thermally fusible link against spring operative means biasing said support means to a receiver non-operative position out of said line of focus.

Abstract: A device for removing pipe attached to a fitting includes cutting apparatus for removing the pipe disposed within the fitting. A wrench apparatus is connected to the cutting apparatus for gripping the fitting to prevent its movement when the cutting apparatus is activated. Alternatively, this device may be used as a reaming device which permits radial movement of the cutting blades into engagement with a pipe after the cutting blades have been inserted within the pipe.

Abstract: A food processing machine for folding rolled sandwich type food products comprising a plurality of conveyor bands for conveying food products through first, second, third and fourth folding mechanisms, the first, third and fourth folding mechanisms each including a U-shaped bracket member with tines extending between said conveyor bands and mounted for movement in an arcuate path over said conveyor bands whereby during passage of said food product said tines lift a front portion of said product and fold it back over a following portion of said product, and the second folding mechanism comprising additional conveyor bands positioned to the outer sides of said first mentioned conveyor bands with the tangent line between the last mentioned bands changing progressively along the path of travel of said bands from essentially a horizontal orientation to a near vertical orientation whereby the side portions of a food product carried therethrough are lifted and folded over a center portion of said food product; addit

Abstract: A fluid sprayer apparatus attachable to an aircraft comprising a center section nozzle tube, a pair of detachable extension nozzle tubes connected to said center nozzle tube by quick disconnect fixtures, a manifold tube for supplying spray fluid to said nozzle tubes, said spray nozzle tubes having a plurality of inlet fittings spaced along their lengths and a plurality of pressure operated spray nozzles each removably attached to one of said fittings, said nozzles comprising a body member, a plunger slidably received in said body member with a pressure piston extending into said fitting, said plunger carrying a seal member engagable with the outlet end of said fitting to close said nozzle to fluid flow and a control insert unyieldably holding said seal member in sealing engagement with said inlet fitting when in a first position and yieldably holding said seal member in sealing engagement with said inlet fitting when in a second position whereby said nozzle may be opened to fluid flow by fluid pressure agains

Abstract: For use in hydraulic workover operations for oil and gas wells, a snubbing element is provided that is made entirely of polymeric material such as polyurethane. According to a preferred embodiment of the invention, the strength and rigidity supplied to the snubbing element in the prior art metallic support ring is now provided by molding that portion of the polymeric annular snubbing element from a polymeric material having a higher density and hardness than that of the polymeric sealing member. The polymeric annular snubbing element thus comprises a high density polymeric support member and a relatively lower density polymeric sealing member.

Abstract: Apparatus for imparting thermal energy to or removing thermal energy from a food product, said apparatus comprising intensive and semi-intensive thermal treatment sections and at least one equilibrating section.

Abstract: Apparatus adapted to deliver a temperature-controlled gas from a common plenum to at least two thermal treatment zones is provided. The subject apparatus is adapted to direct columnated jets of a temperature-controlled gas so as to impinge on at least one surface of food products passing through such zones, and is further adapted to convey food products through such zones in multiple passes in which the food products are subjected to different thermal energy transfer rates in at least two of such zones.

Abstract: A releasable closure device adapted to provide sealing engagement between abutting surfaces by means of a rotatable locking ring comprising a plurality of locking lugs adapted to frictionally engage recessed locking channels disposed in said surfaces.

Abstract: An inker for a lithographic printing press in which ink and dampening fluid are applied to the printing plate by a resilient applicator roller. A resilient ink metering member having a flat metering surface is mounted on a support member which is movable to adjust the angle of intersection of the metering surface relative to a plane tangent to the roller surface. A doctor blade is mounted to remove dampening fluid from the roller surface and is actuated to an operative position upon actuation of the dampener to apply dampening fluid to the applicator roller.
