Abstract: A filter press with filter plates slidable individually by a transport element has on each filter plate a locking hook which cooperates for locking with a locking bolt of the adjacent filter plate. A pivotable blocking element, which in the blocked position, positively blocks the locking hook locking this filter plate against unlocking and is connected to an actuating member which projects into the path of the transport element so that immediately before the latter takes along the relevant filter plate it engages the actuating member and thus pivots the blocking element into a release position so that the filter plate is separable after release of the locking hook. Each respective filter plate to be slid thus remains positively locked to the as yet unopened plate stack until immediately before it is taken along by the transport element and cannot become separated from the stack accidentally.

The water within the water receiving passageway is discharged through a plurality of water discharge orifices with each orifice adapted to discharge a laminar flowing jet stream of water. A plurality of discharge chambers is provided in the outer housing in alignment with the water discharge orifices in the inner housing.

Abstract: A system for segregating and baling textile wastes supplied from a plurality of separate sources embodies a plurality of filling stations which receive the wastes from the separate sources. An upwardly opening portable waste receiving bin is mounted within each filling station with the lower end of each bin carrying a detachable bottom platen. A transfer mechanism moves each bin selectively, back and forth between its filling station and a compression station where the wastes are compressed within the bin. Actuator units in the compression station disconnect the bin from its platen and raise the bin to an upper position about a movable ram to thus expose the bale for final bale out.

Abstract: A cotton ginning system embodying a lint cleaner in which the batt of cotton delivered to the lint cleaner is maintained at an optimum thickness even though the rate of ginning varies. The batt thickness is maintained by correlating the same with the rate of feed of seed cotton to the system. Controls are provided to assure that the batt remains at optimum thickness, and such optimum thickness is assured by sensing the rate of input of seed cotton to the system.

Abstract: Spraying apparatus for cleaning filter plates embodies a support frame which is mounted for movement beneath the filter plates and is adapted to align with each space formed between adjacent filter plates to be cleaned. A spraying unit is mounted for pivotal movement on the support frame selectively to a lowered position beneath the filter plates and to a raised position extending upwardly into the space between adjacent filter plates. A spray dispenser carried by the spraying unit moves within the space to apply spray to the adjacent vertical surfaces of the filter plates being cleaned.

Abstract: A paddle-like member for a fishing lure embodies a flat, planar member that extends forwardly from the front end portion of the fishing lure. At least one outwardly opening cavity is provided in the front end portion of the planar member with the cavity defining a socket for receiving a weight with a friction fit. The cavity is positioned in the planar member at a location so that upon insertion of the weight into the cavity, the center of gravity of the lure is lowered. This in turn, stabilizes movement of the lure and controls the rate and angle of descent of the lure as it is pulled through the water.

Abstract: A spring adjusting device for a self-sealing coke oven door embodies a plurality of elongated, outwardly projecting housings carried by the outer side of the door. Each housing is provided with an elongated passageway therethrough in alignment with an opening through the door adjacent the outer edge thereof. A plunger is mounted for sliding movement through each opening with one end of the plunger engaging a flexible sealing member carried by the door and urging a sealing edge of the sealing member into engagement with the door jamb upon inward movement of the plunger. A compression spring is mounted within the passageway with one end thereof engaging an adjacent end of the plunger. Guide members at each end of the spring retain the spring in alignment with the plunger and out of engagement with the passageway. An actuator carried by the outer end of the housing compresses the spring and urges the plunger toward the sealing member.

Abstract: A fishing lure embodies an elongated body having a fishing line attached to its front end portion and a rearwardly and upwardly extending hook carried by its rear end portion. A plurality of movable weights are mounted within an enclosed cavity provided in the body. The cavity and weights are formed and arranged to permit the weights to move within the cavity and cause the body to oscillate about an elongated axis extending above the longitudinal center line of the lure to thus produce a unique sound, appearance and disturbance in the water which attracts fish.

Abstract: A fishing lure for surface water fishing includes an elongated body having the natural appearance and swimming characteristics of a small bait fish. A plurality of movable weights are carried by the body within an elongated cavity adjacent the rear end of the body. The cavity and weights are constructed and arranged to permit the weights to move within the cavity and urge the body, while floating at rest, to an upstanding position. Upon retrieval of the body along the water's surface, the weights move within the cavity to impart oscillation to the body about an elongated axis extending through the body in opposite directions to produce a rattling sound that attracts fish.

Abstract: A safety lock for a window mounted for pivotal movement about a centrally disposed vertical axis embodies a lock assembly housing mounted on the window sill intermediate the vertical axis and a window jamb. An elongated vertically extending locking member mounted on the lock assembly housing is movable selectively to a locked position with its upper end adjacent the housing and to an unlocked position with its upper end spaced from the housing. A latch assembly housing is mounted on the lower portion of the window intermediate the vertical axis and a vertical side frame member. A connector arm is pivotally connected at one end to a lower portion of the latch assembly housing with its other end engaging the locking member to permit pivotal movement of the window selectively to a closed position and to a limited open position.

Abstract: Disclosed is a process and apparatus for stopping the drawing action of a draw frame whenever sliver breaks. The sliver is pneumatically conveyed into the field of influence of a sensor which generates a signal indicating the presence of the broken sliver therein. This signal is used to stop the draw frame, thus eliminating the production of sub-weight sliver or roving.

Abstract: An airborne target for generating an exhaust plume simulating that of a jet powered aircraft embodies an elongated target body having an elongated combustion chamber therein. An air receiving inlet which faces in the direction of travel of the body communicates with the forwardmost end of the combustion chamber. An expansion chamber between the air receiving inlet and combustion chamber increases the expansion of air flowing toward the combustion chamber while at the same time reduces its velocity. A fuel injector is carried by the body to inject hydrocarbon fuel at a predetermined rate under pressure into the air to thus provide a predetermined fuel-air mixture. An igniter is carried by the body downstream of the fuel injector to ignite the fuel-air-mixture. A flame holder is carried by the body in position for the ignited fuel-air mixture to attach thereto and provide sustained burning after the igniter is spent.

Abstract: To equalize the precoat application over the length of the filter press and/or over the height of each filter cloth, the drainage of at least a part of the carrier medium occurs at at least one, and preferably at a plurality of regularly distributed, drainage points located between the ends of the filter press, and preferably at a throttled rate, so that a pressure is built up in the filter chambers. At least one filter plate, and preferably a plurality of filter plates arranged at regular intervals, is provided with additional drainage orifices for the carrier medium at the upper end thereof with such additional drainage orifices being connected by flexible hoses to one or more filtrate-collecting pipes. The total cross-sectional area of all of these additional drainage orifices is smaller than the total cross-sectional area of the filtrate drainage channels used during filtration.
