Abstract: A fluidized bed electrowinning system and method includes a fluidized bed reaction vessel in which a fluidized bed of conductive particles serves as the cathode for the electrowinning reaction, the anodes being in the form of hollow tubes of electrochemically active material inserted into the fluidized bed and separated therefrom by a membrane. The catholyte and anolyte are separately supplied from an electrolyte supply tank, the catholyte being pumped through the conductive particles to form the fluidized bed and the anolyte being supplied to individual anodes, and are commingled at the top of the reaction vessel before return to the supply tank. Removal of particles from the tank occurs through a part in the side of the tank, the removed particles normally being recycled through a selector valve back into the tank to maintain continuous operation.

Abstract: The present invention is a system and method for oxidation of volatile organic compounds which is stored or held in a suitable storage structure such as an accumulation tank. The volatile organic compound stored in the accumulation tank is taken into the intake port of an operating internal combustion engine wherein the operating and internal combustion engine reduces the volatile organic compounds into carbon dioxide and water which appears in the exhaust gases of the operating engine.

Abstract: The invention relates to a method of dry cleaning textiles which are washed with solvent and dried by hot air, the solvent being recovered after condensation, the invention being characterised in that the solvent concentration is measured at the point where it is highest and temperature is measured, both being measured continuously throughout the whole of the drying process and the values are processed in a computer, and the concentration in the supply of hot air is controlled as a function of the relationship of concentration, acting as the pilot value, to temperature along a characteristic.

Abstract: The present invention is directed to an inexpensive display device and a method of attaching objects such as pictures, notes and the like to appliances. The invention is substantially a flexible, lengthwise deformable band which is extended around the perimeter of an appliance. The band is secured in place by the deformable material creating frictionous contact with the appliance. The objects are attached to the display device by inserting them into at least one channel cut length-wise into the band. A plurality of short channels may also be cut at a selected predetermined angle to the length-wise center-line of the band. The preferred angle being between about 30 and 90 degrees. The device may be configured as a continuous stretchable band or may be made having ends which are adjustably attachable each to the other. The objects are held in place in the channel by the material of the device creating frictionous contact with the objects.

Abstract: A short, tracheostomy length, single use open suction catheter, made of relatively flexible plastic material such as natural or synthetic rubber, polypropylene, polyethylene, polyvinyl chloride, nylon or like material having the flexibility and resilience necessary for use in the suctioning of the airway of tracheostomized patients in order to remove tracheobronchial secretions from such a patient with a tracheostomy tube in place. The tracheostomy length catheter has a fitting for connecting the proximal end (the end nearest the source of vacuum) to a source of vacuum. There is a valve, such as a thumb controlled valve, at the proximal end used for controlling the extent of the vacuum or low pressure at the distal end of the suction catheter (the end nearest the patient). The valve regulates the vacuum by covering or partially covering a vent port with the thumb of the clinician who is doing the suctioning of the patient.

Abstract: The invention relates to an apparatus for the removal of clarified waste water from circular tanks which have a central waste-water inlet. It is notable for a submerged pipe which is constructed as a ring conduit provided concentrically with the vertical axis of the ring tank and is arranged underneath the surface of the clarified waste water in order to draw off the clarified waste water uniformly, the drainage of the latter being regulatable independently of the incoming amount by means of a control system and the water level in the tank being controllable in a constant manner by means of said system.

Abstract: An apparatus and method for perforating corrugated plastic pipe from the inside of the pipe to the outside and the pipe produced by the method. The apparatus has a perforating device attached to an elongated support member. Perforations are created by advancing pipe over the perforating device or by advancing the perforating device into the interior of the pipe. Where the pipe is advanced over the perforating device, a carriage, holding the pipe, is riding on a track which guides the pipe into engagement or into cutting or perforating proximity with the perforating device. The perforating device includes a housing holding motors with cutters attached to them. The cutters cut the inner corrugations or the valleys of the pipe as the pipe is passed over the perforating device. Pipe is perforated by advancing it over a perforating device, and curing the pipe from the inner pipe surface to the outer pipe surface.

Abstract: A device for centrically charging tanks (9) with a spin chamber (1, 10) connected to an inlet (20) and to a vertical downpipe (2, 12) ending seamlessly in a trumpet-shaped mouth (3, 18). Rotary flow charges circular settlement tanks and sand sorters and sedimentation tanks in such a way that the Coanda effect is activated at the trumpet-shaped mouth (3, 18) and in turn causes the rotary outflow of fluid from the vertical pipe (2, 12) to be diverted into the horizontal plane or vertically upwards as well as a radially symmetrical flow in the tank (9). There is a guiding pipe (14, 16) in the downpipe (2, 12) with preferably circular apertures around its periphery and which is open to the atmosphere at the top.

Abstract: The invention relates to an improved cleaning appliance used to clean floors, walls or the like, with a cardanic or semi-cardanic fastening of the handle to the basic body portion or the cleaning device which does the actual cleaning, scrubbing, wiping or other cleaning function. The invention permits the particular appliance and the handle, semi-cardanically attached thereto, to be fixed in a substantially upright position permitting it to be leaned against a fixed object and thus making the handle accessible to the user without the user or operator having to bend over to pick up the appliance. A setting-up stirrup is articulatably attached on the cleaning device and is caused to articulate by an operator thereby engaging behind a projection, screw or peg on the handle or for catching in a horizontal groove of this handle.

Abstract: The invention relates to a method and an apparatus for the hydraulic branching of an open stream having at least one straight main stream of a specific momentum and having one or more branch streams. Deflection from the main stream is brought about using the Coanda Effect. The hydraulically working channel, i.e., the main stream channel has an upstream corner in common with the branch stream channel which corner is rounded in the form of an arc of a circle between the upstream channel and the branch channel and which converges toward the corner and extends opposite that wall of the upstream channel leading toward the corner and forms with the corner an outflow gap, such that the momentum of the main stream flow which emerges, creates the Coanda Effect, thereby deflecting the controlled flow of water into the branch channel.

Abstract: A method and apparatus for testing and evaluation of physical coordination and dexterity in occupational rehabilitation or physical therapy for injury or illness, and for training of retarded or developmentally delayed or handicapped persons. The person being tested attempts to traverse a test pattern with a targeting image or to plot coordinates and connect line segments from instructions, using left and right hands or feet to control motion or plot coordinates in at least two dimensions. Controls can be oriented and configured to test and train motor skills, motions and coordination requirements common to workplace, home or recreational activities. A permanent trace record of the subject's effort, made in the same orientation and scale as the test pattern, provides a means by which test results can be compared directly to the test standard, to previous and later recorded traces by the same subject, and to the traces of other subjects.
