  • Patent number: 5404597
    Abstract: A vacuum assisted toilet wherein a vacuum is applied between upper and lower traps (40,44 in FIG. 2) of a toilet bowl outlet during a flushing, wherein the lower trap is constructed to more reliably assure that an air passage (64) above a pool of water (52) of the lower trap will quickly close near the beginning of a flushing and will remain open between flushings. The lower trap has a lower wall (50) that holds a pool of water (52) with a pool top (62) of predetermined height (A) between flushings, and has an upper wall (60) spaced above the pool top to form an air passage. The upper wall forms a narrow but tall vent (100, FIG. 4) of the air passage, which assures that the air passage will always be open between flushings, and with the narrow but tall vent being quickly closed by water rapidly flowing therethrough at the beginning of a flushing.

  • Patent number: 5386596
    Abstract: A water saver toilet is provided, of the type that applies a vacuum to the toilet bowl outlet to assist flushing, which effectively uses the vacuum. The toilet bowl outlet includes upper and lower trap devices (44, 50 in FIG. 2) connected by a trapway (46), with the lower trap device being initially unobstructed. At the beginning of flushing, the initial water flow causes obstruction of the lower trap device to air flow, and a vacuum is then applied to the trapway to pull out water and debris from the toilet bowl. One toilet (FIG. 5) is of the urinal type, and includes a container (214) lying within a water tank, with the lower end (218) of the container opening to the water tank, and with the upper end (219) of the container connected by a vertical vacuum pipe (221) to the trapway.

  • Patent number: 5381750
    Abstract: A vessel with a rotatable turret thereon is moored in a manner that minimizes turret tilt while avoiding the need to maintain precisely concentric upper and lower turret bearings. A mooring structure (152, FIG. 7) is formed by a group of mooring lines (162, 164) such as chains, with the upper ends of the lines coupled to the vessel through a connecting apparatus (154) that comprises a group of arms (166) each connected to a corresponding one of the lines. Each arm is pivotally mounted (at 170) on the turret to hang therefrom, so the arm transmits primarily vertical forces to the turret and the turret bearing (185) has to support primarily vertical forces. Each arm carries a bearing pad (174) that presses horizontally against a vessel lower bearing ring (182) mounted directly on the vessel hull independently of the turret.

  • Patent number: 5352172
    Abstract: A rope friction exercise device is described which is in the form of a member 12 (FIG. 2) having multiple bars (51-62) about which a rope (30) can extend in multiple wrappings to provide frictional resistance against pulling of the rope. The member has an elongated longitudinally-extending first side (42) and has a first plurality of bars (51-54) spaced along the first side, with each bar having a first end (80) mounted on the side and a second end (74) which is free, so a rope can be wrapped and unwrapped from a bar by merely installing and removing it from the free end, to thereby change resistance to rope pulling. A plurality of parallel bars enables a rope section to extend over and under the bars in a small angle of wrap to enable a small change in rope pulled resistance, in an arrangement that makes it easy to understand how to change rope pulling resistance. A handle 36 (FIG. 6) allows easy adjustment of rope length.

  • Patent number: 5329303
    Abstract: A chart recorder is described, of the type which includes a strip of pressure-markable chart paper (12, FIG. 1) that is slowly moved downpath past a marking station (30) where at least one stylus (32) presses against the chart strip to mark it, which is compact, reliable, and accurate. The marking station includes a first wide but thin belt (52) extending in a loop between a pair of rollers, with the stylus coupled to the belt so as the output of a temperature sensor turns the belt, the stylus moves across the width of the chart strip. A slider (82, FIG. 3 ) coupled to the stylus and belt, can slide along a lateral guide (90) that resists tilting of the slider, to thereby enable it to keep the stylus pressed against the chart strip. Where two styluses are used, a second independently driven belt is coupled to a second stylus with the second belt lying below the first one. A supply roll (20, FIG.

  • Patent number: 5322185
    Abstract: An apparatus is described which can receive a large number of earplugs from a box and dispense one or two of them at a time to a worker. The apparatus includes a wheel (22, FIG. 1) which is rotatable on a frame (12) and which has holes (24) that move in a circular path and that can each receive a single earplug (16). As each hole moves over a dispense passage 18, the earplug in the hole can fall out, and be dispensed. A barrier (42, FIG. 2) lying above the wheel, prevents an earplug from falling into a hole that lies at the passage. The barrier covers only one side (52) of the path (32) of the holes, to allow a deformed earplug to move along the other, uncovered side (54) of the path. The wheel has a narrow slot (80) extending from each hole to the periphery, so a tool can be projected through a frame opening (84) and through the slot to dislodge an earplug stuck in a wheel hole.

  • Patent number: 5312140
    Abstract: A fluid swivel is described, of the type which includes a ring-shaped outer structure (12, FIG. 2 ) that rotates about a ring-shaped inner structure (14), and which form an annular chamber (18) between them and a pair of gap passages (24, 26) between them which are sealed by pressure seals (30, 32). The outer structure includes a body (70) forming part of the annular chamber and a seal ring (72) mounted on an end of the body and abutting one side of the pressure seal. The seal ring is axially shiftable on the end of the body, so that when the body expands radially as a result of high pressure fluid being introduced into the annular chamber, the seal ring does not have to expand a similar amount and therefore does not have to cause a large increase in the width of the extrusion gap (62) at the downstream end of the pressure seal.

  • Patent number: 5305888
    Abstract: A floatation separation method is described for separating pieces of fruit or vegetable of the same type, but wherein desirable pieces have a slightly different specific gravity from the undesirable ones, and all have a specific gravity about the same as that of water. The pieces (12, FIG. 3 ) are placed near the surface of a body of water, and a cloud (40) of tiny air bubbles is maintained in the water. As the bubbles float to the surface they encounter the articles and slightly increase their buoyancy. The increase in buoyancy is slight and uniform, so those articles having a density slightly greater than that of the water will remain at the water surface, while those of a slightly greater density cannot be floated by the air bubbles and will sink to the bottom. The cloud of air bubbles is created by allowing air at about atmospheric pressure, to emerge from apertures in a rapidly spinning rotor that open in a direction primarily opposite to the spin direction.
