Abstract: A material collector for a fluid container having a bottom drain outlet, such as a swimming pool. The collector includes an open top receptacle provided with a perforate side wall or bottom wall. An imperforate skirt extends outwardly and downwardly from the upper margin of the side wall and has an outer periphery spaced from the side wall for engaging the bottom of the fluid container when the receptacle is spaced above the drain outlet. A dome-shaped cover above the receptacle forms a duct with the skirt to permit material, such as debris, to be swept by the flow of the fluid of the container into the open top of the receptacle where the receptacle collects the material as the fluid continues to flow through the perforate wall of the receptacle and into the drain outlet of the container therebelow. A post or line releasably coupled to the receptacle permits the receptacle and the cover to be lifted together out of the fluid in the container and emptied.

Abstract: The liquid jet propulsion unit is driven by the conventional outboard motor. The drive of the motor directly rotates an impeller which draws up the water into an impeller chamber where it is moved by isentropic radially extending impeller blades. These blades have three progressive stages from inlet to outlet, i.e., axial, transition, and radial. In the delivery of the intake liquid to the outlet chamber the twisting turbulence is reduced and is straightened out and is further straightened by the outlet vane to give a stream greater lineal length and force through the outlet nozzle, which drives the craft forward. Since the vertical distance between intake and outlet is only a matter of a few inches, shallow draft boats can be driven successfullyin shallow and rocky water.

Abstract: Apparatus and method for recovering clean solvent from a mixture of solvent and contaminants. The apparatus includes an open top tank mounted in a housing below a sink in which articles to be cleaned with solvent are placed. The sink has a tap through which solvent is directed so that the articles can be cleaned by hand in the sink itself. A disposable, plastic bag is receivable in the tank and the tank is closed by a cover. Contaminated solvent can flow from the sink, through the cover and into the bag in the tank. Contaminated solvent in the bag is heated by heating a liquid surrounding the side wall of the tank and below the bottom of the tank so that the solvent in the bag will vaporize. A tube leading out of the tank carries solvent vapor into a heat exchanger where the vapor is condensed to form clean, liquid solvent, and the liquid solvent is collected in a reservoir. A pump is coupled to the reservoir for pumping liquid solvent to the tap at the sink.

The (poly)ethylene oxide can be in the form of a coating on the outer surface of the cast material or in the resin of the cast material.

Abstract: An apparatus and a method for applying permanent indicia, such as numbers representing calendar dates, on surface portions of plastic containers, such as containers for holding milk. The apparatus includes a heated die and an inked web mounted on a support plate in positions to cause the indicia-forming elements on the die to engage and force a portion of the web into intimate contact with a flat surface portion of a container. The die effectively brands the container and the ink on the web portion is transferred into the branded portion of the container to render the branded portion readily observable. The containers are moved incrementally past the die and web portion by a conveyor. A container holding device is mounted in a fixed location on the opposite side of the conveyor aligned with the die so that each container is held against lateral movement as the die forces the web portion into contact with the surface of the container to be branded.

Abstract: An improved method and material for securing a thin-edged deformable structure, such as a honeycomb core, so that the structure may be machined while it is in a generally stabilized condition. The material is a laminate which is bonded to one side of the structure to be machined. The laminate is then secured by vacuum and the structure is then machined in a desired manner. The laminate includes a first stabilizing layer formed from a mesh of fiberglass, nylon or the like and having relative large openings. The mesh is impregnated with a suitable epoxy or phenolic resin which acts as an adhesive to secure the mesh to the structure. A fabric of nylon or the like is applied over the mesh and bonded thereto. A third and final layer includes a non-porous plastic sheet which permits the laminate to adhere by suction to a vacuum chuck. After machining, the fabric and non-porous layers are removed, leaving the open mesh layer fixed to the structure to stabilize it.

Abstract: A wall assembly comprised of a number of wall panels releasably coupled by clips of improved construction to spaced, vertical studs. Each wall panel has an end face and each clip has a number of tines or teeth which are forced or driven into the end face of the corresponding wall panel. The clip further has a resilient part mounted on a base part which engages the adjacent surface of a wall panel. The resilient part yields in one direction when it engages the adjacent flange of the stud as the wall panel is forced toward the stud in a horizontal direction. This permits the resilient part to pass by and thereby clear the flange of the stud, whereupon the resilient part snaps back behind the flange and thereby releasably couples the wall panel to the flange with the wall panel at the front of the flange. The resilient part is breakable from the body of the clip when the wall panel is pulled in a horizontal direction away from the stud, thereby permitting removal of the wall panel from the wall assembly.

Abstract: A multilevel metallization process which allows fabrication of several types of high density MOS and bipolar integrated circuits. The process uses a pad located under the inter-layer contact opening. The material of the pad is poly-silicon (doped or undoped), a refractory metal, or a refractory metal silicide which is not capable of being attacked during chemical etching of the metallization layers. If poly-silicon is used, it is either doped during its deposition or during contact doping, or it is automatically silicided during ohmic and Schottky contact formations.

Abstract: Apparatus and a method for upgrading low pressure steam or brine, such as from a geothermal well, to prepare the steam or brine for any one of a number of uses, such as for conversion to pure, high pressure, high temperature steam for driving turbines. The system operates in a degasification phase in which a small amount of superheated steam is applied to the brine to scrub the same to cause the removal of concentrated gases therefrom. The degasified product is then pumped to a high pressure, heated countercurrently, and directed through a demineralized phase to remove the salts and solids in a liquid phase and convert the bulk of the water into pure, high pressure saturated steam. The steam output from the demineralizing phase can then be used to produce useful work, such as driving a turbine. In addition to forming saturated steam from geothermal brine, the system can be used to form pure saturated steam from impure water from any suitable source.

Abstract: An agitation tank adapted to contain a slurried pulp or slurry containing particles, such as carbon particles, to be separated from the slurry. The tank has a screen unit removably mounted therein, the screen unit having a hollow body provided with an opening and a screen across the opening to allow the slurry to pass into the hollow body but to prevent the particles in the tank from passing into the hollow body. The slurry in the hollow body can then pass out of the screen unit and the tank through an outlet which communicates with the interior of the hollow body and an adjacent vessel. The screen unit can be removed from the tank to permit replacement of the screen surrounding the hollow body. The screen is removably mounted on the screen unit by a clamp to permit rapid change of the screen if the screen becomes defective.
