  • Patent number: 4894926
    Abstract: A dipstick guide to aid in the insertion of a dipstick into a dipstick tube when measuring the level of oil in the engine or replacing the dipstick in the dipstick tube comprising an upper frusto-conical body whose side converges into one end of a smaller central body or tube portion, the other end of which then diverges into a lower body or frusto-conical skirt, smaller than the upper body, the two opposed frusto-conical bodies having sides which diverge in opposite directions from each other, and a slot extending axially along the length of the guide from one end to the other to allow removal of the guide, sidewise, when the dipstick has been partially inserted into the dipstick tube. An upstanding handle on the upper body facilitates the positioning of the dipstick guide onto the dipstick tube, and allows for the dipstick guide to be manually removed from the dipstick tube, and then moved out of the way of the dipstick.

  • Patent number: 4891459
    Abstract: Entrained pyrolysis of lignocellulosic material proceeds from a controlled pyrolysis-initiating temperature to completion of an oxygen free environment at atmospheric pressure and controlled residence time to provide a high yield recovery of pyrolysis oil together with char and non-condensable, combustible gases. The residence time is a function of gas flow rate and the initiating temperature is likewise a function of the gas flow rate, varying therewith. A controlled initiating temperature range of about 400.degree. C. to 550.degree. C. with corresponding gas flow rates to maximize oil yield is disclosed.

  • Patent number: 4888166
    Abstract: A method of producing submicron titanium diboride from an initial mixture of titanium oxide, boron oxide, and magnesium, by reducing the titanium dioxide and boron oxide with magnesium in an atmosphere including air to yield a resultant product containing submicron titanium diboride and magnesia. The reduction reaction is preferably initiated by locally igniting the initial mixture. The resultant product is then cooled and leached with a leaching solution having a pH in the range of about 0.5 to about 8 to recover the sub-micron titanium diboride.

  • Patent number: 4886044
    Abstract: A hollow, upright cabinet supports therein a cooking grid and a plurality of upwardly facing gas burners which emit infrared head toward the cooking grid. A shield assembly having angled baffles is removeably mounted over the burners to shield the meat directly above the burners on the grid from the infrared rays and protects the burners from the drippings of the meat. The spaced baffles however permit the infrared radiation to pass upwardly, at an angle to impinge on meat at the rear of the grid.

  • Patent number: 4874363
    Abstract: An apparatus and method for providing a colonic lavage to a patient comprises a speculum for insertion into the colon of the patient with the speculum being generally tubular and having a tapered end within the colon with opposing openings formed therein and discharge and inlet openings outside the anal canal. The inlet opening is connected to a lavage liquid holding chamber through an inlet conduit and the discharge conduit is connected to a collection chamber through a discharge conduit. The discharge conduit has a resilient collapsible portion that passes through a pinch valve that can be actuated to close the discharge conduit. In operation, lavage liquid is pumped from the holding chamber while the pinch valve is closed causing the colon to fill with liquid. When the colon is full, pumping is discontinued and the pinch valve opened allowing liquid and loosened fecal matter within the colon to be purged through the discharge conduit to the collection chamber.

  • Patent number: 4867080
    Abstract: A tufting machine is provided with separate motors which drive the main drive shaft, control the feed of the backing material and control the bedrail height. A computer is electrically connected to these motors and to the yarn feed controls. The software indicates patterns to be produced, informing the computer to control the number of stitches per inch of backing, the weight of face yarn per square yard, the pile height, the amount of yarn fed to the needles and the linear length of carpeting produced. The computer also dictates the schedule by which prescribed lengths of additional patterns are produced by the tufting machine and can control a number of such tufting machines. When the pile height is to be changed, the computer automatically controls the main motors for rocking the main shaft, to reciprocate the needles while controlling the yarn feed controls and the motor to the bedrail.

  • Patent number: 4868020
    Abstract: This invention pertains to the fields of graphic arts and graphic communication. The principal use of this invention is to communicate visually with a new graphic method--a method of putting a translucent overlay on one color of pastels uniformly on a piece of paper and then removing it by erasure in order to create a desired image. The paper can be imprinted before the overlay is applied in order to give a foundation for the erasure. One prior method of graphic communication has been to put a color or several colors on a paper nonuniformly to create a desired image. Likewise, another prior method has been computer-generated images on cathode ray tubes. Both of these prior methods require training and skill. Neither are easily accomplished. This new method requires no artistic or computer skill and gives excellent results. Further, this new graphic method can be renewed by rubbing the translucent overlay back to a uniform color and an additional image created by erasing again.
