  • Patent number: 4852596
    Abstract: A slide irrigating unit has two plexiglass boxes, an inner box forming an irrigating chamber and an outer box forming a drain box. The outer drain box is tightly sealed and its inner walls form the perimeters of the inner box which is open at the top. PVC tubing extends through the outer box and underneath the inner box. This tubing is attached to a fresh water source. The fresh water flows into this PVC tubing and under the bottom of the inner box. Water emerges from this PVC tubing through holes in the bottom of the inner box. As the water level increases in height, it rinses racks of stained microscopic slides that have been inserted into the inner box from the top. The inner box contains drainage holes approximately one inch from the top of the open inner box. The stain contaminated water rises from the bottom of the inner box and drains through these drainage holes into the sealed outer box. The stain contaminated water exits the outer drain box through a PVC drainage pipe in the bottom of the outer box.

  • Patent number: 4850556
    Abstract: A pot cover holder is made of preformed wire with two sides. An inner side has two suction cups attached to the top. The pot cover slips between the two sides with the handle of the pot cover resting on the indented middle of the outer side. The suction cups are used to attach the invention to kitchen walls or sides of kitchen utilities such as a stove or refrigerator. The bottom incorporates a catch function to trap moisture or food run-off. The holder eliminates the need of placing a pot cover onto a countertop where burns, water stains, water or food run-off and limited space are problems. The invention allows the user to place the pot cover in an out-of-the-way area where the above problems will not exist.

  • Patent number: 4819370
    Abstract: A fan blows air and insects in the direction of the screen. A flexible monofilament rotates adjacent the screen on the opposite side of the fan. Lights within a box attract insects, and the fan draws the insects onto the screen. The rotating monofilament kills the insects and cleans the screen, and the insects remains are swept into circular gutters and fall into a collection drawer.

  • Patent number: 4812040
    Abstract: Sample material is sputtered from an orifice in a disc mounted in a hollow cathode. A plasma plume is ejected from the orifice and the material sputtered from the smaple is transported directly into the base of the plasma plume. Collisions with particles in the plasma plume excite the sputtered material. Light emission and absorption from the plume are measured and ions in the plume are measured. A chamber surrounding the plasma plume is maintained at about 1 torr. About 15 cc's per minute of argon are supplied to the hollow cathode at 2 torr. The power supply supplies about 200 volts at about 0.10 amps. Low energy argon ions strick the disc at the end of the cathode tube and sputter atoms off the aperture. Atoms collide with particles in the plasma causing excitation, photon emission and ionization of atoms which are measured by optical and mass spectrometers.

  • Patent number: 4776583
    Abstract: Stationary exercise apparatus has a frame, a chain with a seat and back adjustably mounted on the frame and a boom extending forward from the frame. A crank shaft is journaled in a gear mount at a distal end of the boom, and cranks and pedals are connected to the crank shaft. An outer telescopic member of the boom is fixed to the frame, and an inner telescopic member slides within the outer member and is clamped to the outer member. A drive shaft extending through the inner member is coupled to a flywheel and an energy absorber with an electrical feedback controller to vary the resistance as speed varies. The chair is mounted on a trunnion on side rails mounted on upright members. The fixed portion of the boom and the forward end of the rails is supported on an upright member which is welded to the leg of an "I" shaped base.

  • Patent number: 4768958
    Abstract: An alignment plug for mounting a laser beam projector assembly on the barrel of a weapon, comprising an elongate body (10) of substantially cylindrical cross-section of which a first body portion serves for location within the muzzle end of the barrel and a second body portion serves for attachment of the projector assembly. A window (17) in said plug serves for entry of light emitted on detonation of a blank round, the light being transmitted to a light detector (14) by a light guide (16) to initiate projection of a coded laser beam. Aperture means (8, 9) extending axially of said plug serves to relieve the pressure of the detonation to the exterior of the barrel.

  • Patent number: 4720022
    Abstract: A beverage can is provided with a tab having opening and sealing portions. The tab is riveted to the can lid in a central portion thereof with the opening portion being adjacent an openable area of the can lid which is defined by a continuous score line.The can is opened by lifting the sealing portion of the tab which causes downward movement of the opening portion which in turn impinges upon the openable area of the lid until an opening is formed. After forming the opening, the tab is rotated 180 degrees until the sealing recoverable portion is juxtaposed over the opening, thus covering the opening to keep out foreign matter. The tab is then pushed downwardly so that the sealing portion is fitted into the opening, thereby affecting a seal.
