Abstract: A solid state control device is disclosed for gradually controlling the turn on and turn off of a light bulb. The light bulb is connected to an AC power source through a full wave rectifier having a semiconductor switching circuit connected across it which short circuits the full wave rectifier when an SCR or triac in the semiconductor switching circuit is turned on. A capacitor is normally charged to turn off the SCR or triac when a mechanical on/off switch forming part of the semiconductor switching circuit is in the off position. Upon turning the switch to the on position, the capacitor is discharged to slowly turn on the triac or SCR to short circuit the full wave rectifier and actuate the light bulb. These same circuit components are used when the switch is turned to the timed off position to slowly turn the triac or SCR off which thereby slowly turns off the light bulb.

Abstract: In the transplanting of seedlings, such as, tomato plants, soil prepared to receive the plant seedlings has a mulch layer of sheet material spread over the area in which the plants are to be grown and spaced holes are formed through the sheet material and into the soil with a seedling then introduced into each hole. Thereafter, a generally tubular protector is inserted through the sheet material into the soil surrounding each seedling so that the peripheral exterior of each protector is closely surrounded by the sheet material at the perimeter of each hole with an upper portion of each protector extending above the sheet material to enclose the stem portion of the seedling and a lower portion of each protector embedded in the soil beneath the sheet material to surround the root formation of the seedling. Each protector may have a downwardly tapering form where it encloses the seedling.

Abstract: Cured compacted products suitable for use as landfill materials, embankments, roadbase compositions and the like are produced by the described method from fly ash-containing waste materials obtained by a lime based dry scrubbing flue gas desulfurization operation. In this method the dry fly ash-containing waste powder, which also contains calcium sulfite or sulfate reaction products and unreacted lime, is contacted with a predetermined amount of water and mixed under critical mixing conditions to provide a powder/water mixture which is placed at a suitable utilization site, e.g., a landfill disposal site, and compacted under sufficient load to achieve at least about 70% of the laboratory dry density. The resulting products have compressive strengths after curing of at least about 25 psi and permeabilities of less than 1.times.10.sup.-5 cm/sec.

Abstract: A method and apparatus for splitting a log substantially along the grain into a plurality of sector-shaped segments are described. The apparatus comprises at least one sector splitter ring having a plurality of blades, a support for locating the splitter ring in a log movement path, means for pushing the log axially along a log movement path, a rotating backplate for supporting one end of the log being pushed along, which backplate is adapted to tilt and allow the backplate-supported end of the log to rotate as the log is pushed through the splitter ring, and guide means adapted to retain the floating backplate in the log movement path. The process comprises forcing one end of a log axially against and through at least one splitting blade, the other end of said log being in contact with a backplate that can tilt, and permitting relative rotation between the log and the splitting blade so that a split occurring in the log from the splitting blade substantially tends to follow the grain in the log.

Abstract: A device for mounting a vehicle wheel having a hub on a support has a roller bearing comprising two rows of rolling elements and an inner unit defining raceways for the rolling elements and defining at least one end face provided with frontal radiating splines, this unit consisting of a single ring which is axially clamped between two faces, of which one face is associated with the support and the other face pertains to the wheel hub splines being provided on the face of the hub which fit and engage these splines on the single ring.

Abstract: The present invention concerns copying apparatus which automatically controls the quality of copies. The copying apparatus includes a density detector for detecting the frequency of occurrence of density values along a scanning line of a document to be copied, i.e., the frequency distribution of density values is determined. When the frequency distribution has at least three maxima, a smoothing device smooths the frequency distribution via a predetermined filter function till the frequency distribution has one or two maxima. In the event the frequency distribution has one or two maxima, a density detecting device detects at least one density value according to a maximum or minimum value of the frequency distribution. A control device then controls the copy quality of a reproduced image according to the density value.

Abstract: A furniture is provided of a door formed by a series of uniformly sized panels which are movable from a closed position, in which they are coplanar one with another, to an open position, in which they are parallel and folded on one side of the furniture itself. The panels are connected together by means of a parallelogram linkage system which allows the panels to be moved from the closed position to the open position by means of a single control. The panels slide in an upper guide and a lower guide of the furniture and fold onto the left hand side of the furniture, allowing full access to the furniture itself. The parallelogram system comprises two sets of rods which are substantially identical and arranged between an upper side of the panels and the upper guide of the furniture and between a lower side of the panels and the lower guide, respectively.
