Abstract: Liquid is contained in a source container and oil is removed from the source container and deposited into a destination container. The apparatus includes a housing having a base, at least one wall upstanding from, and encompassing the periphery of, the base, and a top cover. A two-sided piece of material made of rubber, nylon, vinyl, or other oil gathering capable material forms an endless belt or ribbon. At least one scraper device mounted within the housing facilitates removal of oil from the material.

Abstract: An inlet distributor for use in downflow reactors or contacting vessels removes debris from the feedstream that could otherwise plug the top of the catalyst or particle bed surface. Gaseous streams are charged into the inlet distributor and debris is separated from the inlet stream and accumulated in the bottom of the distributor. Fluid flow in the bottom of the distributor is minimized to prevent reentrainment of debris into the gas stream as it leaves the distributor.

Abstract: A submicron particle filter unit of the Hepa type adapted to be interposed between a source of pressurized gas and a work-processing region to provide an environment therefor free of particles and other contaminants.

Abstract: A biological treatment system and method is provided for treating wastewater from a treatment plant which provides primary and secondary treatment. An aggregate-filled bed enclosed by a water-impervious barrier is used to receive and cleanse the wastewater using the roots of turf grass grown on the top of the bed. Wastewater is introduced near the bottom of the bed and flows generally upwardly through the voids in the media, passing through the root system of the turf grass. Wastewater is withdrawn from the bed at a higher level than it is introduced. The top surface of the bed remains dry and is capable of supporting pedestrian and vehicular traffic. A recirculation system maintains the generally upward flow of water through the bed. Transpiration reduces the volume of the wastewater and the biological cleansing action of the roots cleanses the wastewater. Alternative forms of the bed are described.

Abstract: A sorption column for waste-gas cleaning having at least one vat containing a solid stationary sorbent and connected with a lower gas connecting piece and an upper gas connecting piece. The lower gas connecting piece has a coupling member. The vat adapted to be placed on the lower gas connecting piece as a valve in its cover and a valve in its bottom. The upper gas connecting piece has a coupling member. The coupling member of the lower gas connecting piece is adapted to be joined with the valve in the vat bottom and the valve in the vat cover. The valve in the vat bottom and the valve in the vat cover open when joined with the coupling member of the lower gas connecting piece so as to form a gas space communicating from the lower gas connecting piece to the upper gas connecting piece.

Abstract: The present invention discloses a vacuum-assisted vapor recovery system for loading vessels with volatile materials such as liquid hydrocarbons, including gasoline and distillates, which system utilizes a series of interlock premissives and vacuum controllers to maintain a vacuum on the vapor header of the vessel being loaded, which vacuum is within a desired, predetermined level. The system is further arranged and adapted to shutdown the filling of liquids into the vessel should a vacuum leak be detected or should any other malfunction of the vapor recovery system or the liquid filling system arise.

Abstract: A method and apparatus for precision molding soluable polymers is disclosed, in order to form an exact and precisely shaped product, such as contact lenses and surgical implants. A preferred mold for forming contact lenses includes a female part having an indentation and a sharp circumferential edge surrounding the indentation. The mold also includes a male part which is adapted to contact the sharp circumferential edge of the female part to form the molding cavity between the indentation of the female part and the male part. A semi-permeable gate is formed between the female part and the male part for introducing coagulating fluid into the molding cavity while preventing the escape of the polymer solution from the molding cavity. The semi-permeable gate allows the diffusion of the coagulating fluid into the molding cavity at a faster rate than the rate of diffusion of solvent out of the molding cavity.

Abstract: A unitary liner (36) for use in a dual inner and outer cyclonic vacuum cleaning apparatus (10) is described. The liner has a rigid receiver member (38) that collects dirt separated from the airflow by the inner cyclone (12). The receiver is integrally bonded to a flexible container portion (37) that lays over the inner surface (11D) of the outer cyclone (11) to collect dirt separated from the airflow by the outer cyclone. The container portion (41) can also be a rigid member bonded to a rigid receiver (42). Also, the rigid container portion (45) can provide the outer cyclone and be bonded to a rigid receiver (46). The liner collects separated dirt from the inner and outer cyclones and is easy to remove and replace from the cleaning apparatus by removing the cover (13) which supports the inner cyclone, from the outer cyclone to expose the liner when the vacuum cleaner becomes full of dirt. A liner (130) for a tank type, dual inner and outer cyclonic vacuum cleaning apparatus (110 ) is also described.
