  • Patent number: 4234014
    Abstract: A processing apparatus for compressed air comprises a body defining inlet and outlet passages leading to a bowl supported by the body. The bowl is of composite construction comprising a flexible inner bowl and a high impact strength outer bowl formed from polycarbonate for protecting the internal bowl from external damage. The inner bowl has an annular flange trapped between the outer bowl and the body to form a gas-tight seal between them, and is formed from a material which will protect the outer bowl from solvent and/or chemical attack. The outer bowl has a small vent to atmosphere to allow controlled venting of the compressed air in the event of inner bowl failure without allowing fragments from the inner bowl to pass through the vent. Both bowls are made of translucent or transparent materials so that the contents of the inner bowl can clearly be seen.

  • Patent number: 4231039
    Abstract: Method and apparatus for measuring the speed of a land vehicle over a surface. A narrow beam of RF energy is directed toward the surface at a substantial angle. Reflected RF energy is mixed with that transmitted to produce Doppler signals having a spectrum. The spectra of the Doppler signals are normalized by the Doppler signals being applied to an AGC circuit so that the maximum amplitudes of the spectra are substantially constant and being applied to one or more tracking band pass filters which eliminate unwanted frequency components in the spectra. From the normalized spectra, output signals are produced from which can be determined the speed of the vehicle relative to the surface.

  • Patent number: 4230162
    Abstract: In accordance with this invention a wood working machine is provided which facilitates the sequential working of opposite sides of a wooden work piece to form a flange for a cable reel. The work piece is grippingly held against a work piece support while the support moves downwardly to permit working on one side of the work piece with a first set of working elements and then moves upwardly to permit working on the other side of the work piece by a second set of wood working elements after which the support returns to its initial position and the work piece is released for removal from the apparatus.

  • Patent number: 4226187
    Abstract: The safety equipment is used in conjunction with a conventional ski lift system having a series of towers plus turnaround stations, arms extending out from the towers, and single or multiple bogey beams, each having at least two rope support sheaves. A continuous cable, or rope, extends over all of the support sheaves and around the end stations. The safety features include a secondary sheave mounted beside and outward of the primary sheaves with its upper margin below the upper margins of the primary sheaves. If a rope is displaced from the primary sheaves it will fall into the groove on the secondary sheave. To prevent displacement from the secondary sheave, a star wheel is mounted above the sheaves for rotation on a horizontal axis and the radial fingers pass down close to the outside of the secondary sheave and overlap its upper portion. The gap between the sheave and the guard fingers is so small that a rope cannot fall between them.

  • Patent number: 4218039
    Abstract: A form tie and a method of making the same is provided. The form tie includes an elongated hollow protective sleeve contiguously surrounding a portion of the form tie to facilitate the removal of the form tie portion from a settable casting, such as concrete. The thickness of the sleeve is minimized so that the cross-sectional area of the form tie portion which includes the surrounding sleeve is also minimized.

  • Patent number: 4216839
    Abstract: An electrically powered vehicle achieves maximum structural strength with minimum weight by utilizing a combined body and chassis formed entirely of plastic material, molded and bonded into an integral composite structure which includes a central, hollow longitudinal beam, top, bottom, and side panels of the vehicle body portion, and a power unit supporting chamber at the forward end closing the forward end of the beam and tying it to the side panels. The beam holds the batteries, and the chamber contains all of the components of the power unit including the controlling device. The structure is thus as rigid and light as possible, in addition to eliminating any possibility of any unwanted grounding or electrical paths. The only metal in the vehicle is that of the additional components such as road wheels, suspension members, steering, and power unit and the fasteners and brackets used to retain them in mounted position.

  • Patent number: 4214984
    Abstract: A process is disclosed for separating a relatively more magnetic material from a relatively less magnetic material comprising passing the material being processed through a plurality of regions, each region having a relatively more magnetic segment and a relatively less magnetic segment, such that the plurality of regions are arranged so as to comprise alternating relatively more magnetic and relatively less magnetic segments, which regions are aligned at an angle other than 90.degree. in the plane of the surface of the regions to the direction of the resultant nonmagnetic forces such that the relatively more magnetic material has a tendency to travel at an angle to the direction of flow of the relatively less magnetic material thereby effecting the separation. Preferably each of the regions is aligned from 0.degree. to about 30.degree. with respect to each adjacent region.

  • Patent number: 4213452
    Abstract: A compound splint, primarily for use after nasal surgery, prevents edema fluid from splaying the bones apart so that they will grow back together and includes a base layer of adhesive tape applied directly to the nose, a secondary component of flexible material adhesively secured to the base layer and having an intertwining surface on its outer face, and a primary restraining component. The latter includes a panel of malleable metal and a layer of fabric secured to one face of the panel, the fabric having an interlacing surface. In use, the primary component is applied to the central portion of the secondary component with portions of the interlacing surface engaging central portions of the intertwining surface. The side portions are then pressed inwardly against the sides of the nose to the desired final shape with the remaining portion of the interlacing surface engaging the remaining portion of the intertwining surface.

  • Patent number: 4210932
    Abstract: Method and apparatus for optically recording and reproducing video signals. The intensity of a laser beam is modulated as a function of the amplitude of the video signals. The modulated laser beam is caused to conduct a raster scan synchronized by standard TV sync pulses and used to expose photographic film. Horizontal and vertical sync bars of contrasting optical density are recorded beyond the borders of the raster. The developed film is a directly viewable reproduction of the image scanned to produce the video signals recorded. To reproduce the video signals, an unmodulated laser beam conducts a raster scan of the developed image recorded on the film. The intensity of the scanning beam is modulated by the optical density of the film and converted to amplitude modulated electrical signals, a reproduction of the video signals recorded.
