Abstract: A method of removing impurities from staple fibres in ringless spinning and a device for performing said method. The impurities are ejected immediately after being contacted by the combing roller into a withdrawing space by the effect of the acceleration imparted thereto by said contact. Spinning units including a fibre separating mechanism and a rotary underpressure spinning chamber are employed. The inlet or the guiding walls for said impurities are directed in view of the separating roller tangentially. The withdrawing space can be connected to the central sucking device of the machine.

Abstract: A well completion method is provided wherein an inflatable packer is positioned in an open borehole of a well opposite a formation from which or into which a fluid is to flow. Cement is then forced into the packer to expand its packing element into contact with the wall of the borehole at the formation. The cement is allowed to set and then at least one perforation is made from the interior of the packer through the cement and packing element to the formation. A well system is also provided in which the well is equipped with such a packer so installed and having such a perforation.

Abstract: A system for plotting the total luminescence spectrum of a sample comprises a spectrofluorometer including excitation and emission monochromator stages having operating wavelengths dependent on applied stepping pulses, and an X-Y plotter having a marking pen synchronized for movement along X and Y axis with changes in the wavelengths of the monochromators. A control circuit generates pulses to incrementally step the emission monochromator and horizontally scan the marking pen. A level detection circuit monitors the output of the spectroflourometer and activates the pen upon attainment of a desired contour level. Limit circuitry incorporated in the control circuit momentarily actuates the excitation monochromator following each horizontal scan to increase the excitation wavelength for the subsequent emission scan to complete the plot.

Abstract: A device for enabling a diver to determine his relationship to the true horizon in deep and murky waters or when physiological sensations are of little value is described. An attitude sensor, incorporating a series of mercury switches, usually at the back of the diver's helmet or head, is coupled to a series of light emitting diodes equally spaced around the periphery of the face plate of the diving mask or helmet so as to simulate the natural observation that the half space above the horizon is illuminated while the half space below the horizon is not.

Abstract: A pre-coated body implant, such as, for example, a hip prosthesis, in which that portion of the implant that attaches to or is inserted into a skeletal member of the body has a pre-coating of a material (e.g., an acrylic material) covering all or most of said portion and bonded thereto.

Abstract: A prosthetic device which is adjustable in the transverse plane includes a flanged element moldable in a plastic socket and an element having a toothed superior surface. The plastic socket is formed about the flanged element while using the toothed superior surface as a mold surface. A fastener engages the toothed superior surface and this affixes the formed socket to the toothed element. The fastener may be loosened so that incremental rotation of the toothed element relative the socket is permitted.

Abstract: Pools of all peripheral shapes of either above or below ground construction with single slope or flat bottoms when not in use may be equipped with a rigid structurally safe traversible completely dry surface deck or decks for domestic functions and to simultaneously insulate the surface of the water with which it is in contact but when pool is in use such a deck or decks are to be readily set at any depth in the pool until it or they become finally a false bottom by means of control by external low pressure hydraulic cylinders operated from the pool circulating system per medium of a single readily operable but safety positioned three-way valve.

Abstract: A toilet tank has water supply and overflow ducts which are integrally formed with the base and walls of the tank. The water supply duct is connected to a water inlet at one end to supply water to the tank and has an inlet valve at its other end to control the supply of water to the tank. The overflow duct is open at its top to receive overflow water in the tank and is coupled to the toilet basin to pour the overflow water into the toilet basin.

Abstract: A swimming pool lift installation for the handicapped employs a platform for carrying a wheelchair that is lowered and elevated with the platform so that a handicapped person can sit on his chair and be lowered into the pool for swimming away from the chair and can leave the pool by swimming back into the wheelchair. The chair is releasably secured to the platform so that there is no danger of it being rendered unstable by its buoyancy in the water and so that it can be wheeled on and off the platform. A water hydraulic system operates the lift to avoid contamination of the pool.
