Abstract: A flexible wrapping material comprising a film laminate is provided for packaging of food products which is resistant to flex-cracking and pinhole development, is impervious to liquids and gasses, and exhibits the property of grease-resistance without the use of adhesives to promote bonds between the layers. The film laminate consists of an outer layer of heat-set, biaxially oriented polymeric material followed by a layer of polymeric material, a layer of oxygen barrier polymer, a layer of biaxially oriented polypropylene, a special grease-resistant polymer, and an inner layer of heat-sealable polymeric material. The film laminate is made by bonding the outer surface layer of heat-set, biaxially oriented polymer to a substrate in which an oxygen barrier material is carried on a biaxially oriented polypropylene/special grease-resistant polymer by means of an intermediate layer of polymeric material.

Abstract: This invention relates to a rotary type latch for sliding screen doors wherein the rotary member is molded from a plastic material such as a polycarbonate and which is rotatable in either direction for universal application to either right hand or left hand door operations. The rotary latch engages a slot in a door pull molded from a similar plastic material and contacts the screen door frame through the slot to cam the door against a retaining channel mounted on a door frame. The rotary latch includes a plurality of flat cam faces affording multiple locking positions and which necessitate positive lock rotation to enable the latch to be disengaged. This latch mechanism is of particular usefulness for application to sliding patio screen doors where the screen door closes into a pocket within the side jamb of the patio door frame.

Abstract: A method and apparatus for treating a continuous stream of organic wastewater using highly concentrated activated sludge (10,000 mg/l MLSS), elevated atmospheric pressure, and high levels of dissolved oxygen. The apparatus consists of three pressurized vessels linked in series by piping, and maintained at equal pressure by means of a common manifold.The first vessel receives the mixed liquor consisting of macerated sewage and return activated sludge and thoroughly aerates it with diffused air bubbles. The liquor then flows by gravity into the second pressurized vessel where flocculation and further aeration occur. From an overflow/transfer box in vessel 2, the liquor flows by gravity into the bottom tier of the third vessel which functions as a cyclone separator. The concentrate is drawn from the bottom of the vessel by a return sludge pump and recycled to the first vessel. The centrate rises into the upper tier of the third vessel where it is clarified and discharged as tertiary quality effluent.

Abstract: This invention relates to an insulating device to be mounted at the inner side of an existing window and includes a plurality of spaced apart film curtains mounted on a roller at the top and having a rigid bar at the bottom adapted to run in channel shaped side tracks, with compressible sealing members in the track that are displaced by passage of the rigid bar and which then spring back to engage the marginal portions of the respective film curtains to press them against the side walls of the tracks to provide a sealed unit effectively sealing the side edges of the curtains against the circulation of air at these points.

Abstract: The invention relates to a seed planter having furrow forming means in association with a pair of furrow closing wheels each of which is independently mounted relative to the suspension of the other so that each spring biased suspension arm is pivotable to enable each closing wheel to be raised, or lowered, independently of the other wheel in response to ground conditions encountered in the operation of the planter. The closing wheel mounting also includes means for adjustment of each wheel whereby the angle of attack of each wheel may be varied and importantly enable adjustment of the wheel spacing so that the distance between the wheels can be adjusted and enabling the wheels to be set to run straight with the direction of travel of the planter and at any desired seed planting depth.

Abstract: A fluoroelastomer hollow glass microsphere coating has been found to provide new and unexpected corrosion resistance to metal surfaces for protection against severely corrosive environments. The coating comprises a fluorocarbon elastomer and 3-50% by volume of hollow glass microspheres or microballoons having a size in the range of about 2-300 microns, preferrably 20-200 microns. The hollow glass microspheres or microballoons substantially increases the corrosion resistance of a fluoroelastomeric liquid composition, yielding new and unexpected thermal and chemical resistance, particularly when the coating composition is applied in two or more layers.

Abstract: The invention is directed to a stop device for a lift type overhead door such as may be counterbalanced by springs and cables and having guide rollers operating in guide tracks at opposite sides of the door. The stop fixture is disposed one at each side of the door and includes a pivoted door stopping dog having an operating arm extending generally parallel to a door supporting cable. The dog is positioned at one side of a track flange directly opposed to a roller at the opposite side of such flange and the dog with its operating arm are tied to this roller in a fixed dimension relationship. The operating arm is connected to a door supporting cable so that if the cable breaks the arm is immediately actuated by a spring to swing the dog into engagement with the track flange, backed up by the opposed roller at the other side of the flange, to grip the flange therebetween and thus prevent the door from falling.
