  • Patent number: 4390564
    Abstract: A process and apparatus allows continuous or semicontinuous finishing of doors. The doors are fed to the finishing machine and are conveyed through a series of finishing stages. Sanding, staining, drying, lacquering (finish-coating), drying, cooling, and buffing in the machine leave a completely finished door to exit the machine. Automatic stacking of finished doors is easily accommodated. Water-reducible stains and lacquers are readily used in this novel process and apparatus to reduce health and fire hazards. The process greatly reduces the time required to finish a door.

  • Patent number: 4389908
    Abstract: Partial locking for a fluid-locked planetary gear used in a differential or the like is obtained by causing oil to be squeezed between the gears of a planetary gear train, thereby providing increased resistance to movement, or partial locking, of the gears within the gear train. Improved partial locking for a fluid-locked planetary gear train is provided by loosely mounting planet gears for movement within the chambers which closely surround the partially locked planet gears. The driving and reaction forces on the loosely mounted planet gears permit the planet gears to move so that their peripheral ends come into close engagement with the walls of the chambers in which the gears are mounted to further increase the fluid resistance to movement of the gears. To obtain similar partial locking characteristics in either a forward or a reverse direction, the planet gear pairs and their corresponding chambers are reversed in their relative positions.

  • Patent number: 4388772
    Abstract: An adjustable sight for firearms of the type having a trapezoidally shaped dovetail extending transversely across the upper rear end of the firearm and a sighting bead projecting upwardly at the front of the slide. The adjustable sight includes a trapezoidally shaped base which replaces trapezoidally shaped, fixed sights normally mounted in the dovetail. The base is frictionally secured to the slide by a set screw extending through a threaded bore in the base which is torqued against the lower wall of the dovetail. A transverse slot formed in the base receives a sight blade having formed therein a notch projecting downwardly from its upper edge. The blade is held in place by a blade set screw mounted in a second threaded bore in the base. The set screw intersects the slot at an acute angle, and its end is sufficiently pointed so that its lower surface contacts the lower edge of an aperture formed in the blade.

  • Patent number: 4387615
    Abstract: To reduce the possibility of a kick by a chain saw when cutting on the end of the bar, this invention provides cutter elements having spurs to cock the elements when the elements engage the idler sprocket on the end of the bar. As the elements begin to move in an arc around the idler sprocket, the spurs ensure that the leading depth gauge of the element does not fall away to expose the trailing teeth to too great a depth of cut. Instead, at any position in the arc, the spurs ensure that the depth between the depth gauge and the tooth of each element remains substantially no greater than the depth between the depth gauge and the tooth when the element is moving in a straight line. Preferably, the spur cocks the element so that the depth gauge is effectively higher than the tooth (i.e., the radius of the arc of the outside edge of the depth gauge is larger than the radius of the arc of the outside edge of the tooth).

  • Patent number: 4388303
    Abstract: A method to reduce animal browsing damage to plants comprises the step of inducing a nonphytotoxic dosage of selenium into the foliage of the plants at a level sufficient to repel animals. The method is particularly suited for use in reforestation of pines, firs, and other conifers. The selenium is systemically absorbed into the plants after application to the surrounding soil in the root zone. Selenium compounds having a valency of no more than 4.sup.+ are applied to the soil around the plants to induce absorption in a preferred method.

  • Patent number: 4388254
    Abstract: A blasting composition, method and system for making such is disclosed. The blasting composition is a homogeneous slurry-type blasting agent containing a major amount of water and a relatively small amount of a particulate fuel, preferably a particulate metal fuel. The blasting composition is made by premixing the fuel with water and a gelling agent to form a stable suspension of fuel in the water, metering the suspension of fuel into a dry particulate mixture of an inorganic metal oxidizer and a gelling agent, and slowly tumbling the mixture a short time sufficient to obtain a uniform composition without desensitizing the composition to detonation.

  • Patent number: 4388352
    Abstract: Controlled release compositions are made by a distillation method to include chemical impregnants (such as animal repellants, pesticides, herbicides, fungicides, plant growth stimulants, perfumes and deodorizers, fertilizers, and drugs) in biodegradable, microporous structures. Each microporous structure collapses upon drying but swells upon rewetting to allow the impregnant entrapped in it to diffuse from the structure. Never-dried wood pulp is a particularly desirable microporous structure because it has large pores initially, a large surface area initially, and demonstrated swelling capability. The method is particularly useful when the impregnant is insoluble in the fluid initially within the microporous structure and when the solvent for the impregnant is immiscible with that fluid.

  • Patent number: 4386762
    Abstract: A low-cost fence is essentially free from ground rot. The novel fence post of this invention capitalizes on the structural rigidity of rectangular tubular members. The fence post has a concrete reinforcing rod projecting downwardly into concrete from the tubular member and small-dimensioned lumber bolted to the tubular member and extending upwardly from the other end. This fence post makes it easy to construct a variety of fences, all of which reduce toenailing and nail bracketing by using spanning rails. Long rails span fence posts in a staggered pattern, thereby gaining additional cantilever strength while reducing the number of posts required.

  • Patent number: 4386614
    Abstract: A system for storing time-varying kinesiograph waveforms and continuously displaying the stored waveforms on the screen of a cathode-ray tube (CRT). In a recording mode, the waveforms are periodically sampled, digitized, and then stored in a block of random access memory reserved for that waveform. In a display mode, the Y axis of the CRT is driven by a digital-to-analog converter which receives digitized samples from the memory block corresponding to the displayed waveform. The X axis of the CRT is driven by a second digital-to-analog converter, which, in an X-Y mode, also receives digitized samples from a selected block of memory. In a sweep mode, the X axis digital-to-analog converter receives the continuously incrementing memory addresses, which read out digitized samples from the memory block for the displayed waveform. The system may also display an expanded portion of a waveform in the sweep mode by incrementing the memory address from one of several predetermined values.

  • Patent number: 4385905
    Abstract: A system is disclosed for the conversion of solid carbonaceous fuels to combustible gases having a high energy content. The system utilizes a two-stage reaction system where a particulate fuel is entrained in a high velocity, hot gas stream emanating from a fixed-bed char reactor, the particulate fuel delivered to a gasification reactor by the hot gas stream while being rapidly heated (fast pyrolized). The gases produced are drawn a fixed distance through a bed of char at the bottom of the gasification reactor, after which they are withdrawn from the reactor and cooled. To promote methanation, the generated gases, after passing through the fixed bed of char in the gasification reactor, exit the reactor through a dip leg within the reactor filled with a catalyst which promotes methanation.
