  • Patent number: 6082636
    Abstract: In a washer nozzle assembly, the upper lip portion defining a nozzle opening extends more forwardly than the lower lip portion so that the part of the washer liquid directed upward is blocked by the longer upper lip portion, and the upper part of the spray pattern includes more liquid droplets of larger sizes as compared to the prior art. Thus, the loss of washer liquid by being flown above the windshield at high speed can be reduced, and the spray pattern of the washer nozzle assembly can be optimized for all speeds.

  • Patent number: 6068201
    Abstract: A figure eight mechanism moves a thermal spray gun over a substrate such that the deposit pattern has a figure eight configuration. The mechanism and thereby the thermal spray gun and the pattern are traversed along the substrate. The mechanism is such that, when driven by an input drive of constant speed, the deposit travels along the configuration at a non-uniform velocity. A drive system provides an input drive with varying speed so as to reduce the non-uniformity of the velocity. In one aspect a motor has varying speed, and in another aspect a linkage between a constant speed motor and the mechanism provides the varying speed.

  • Patent number: 6068198
    Abstract: A generator/dispenser for mono-dispersed aerosol, with droplet size precisely controlled by a stepper motor and a nozzle array having a great number of operational micro-vias, and with fluid volume dosage control. A specified dose is delivered over an accurately controlled interval of time, by decrementing the volume of a fluid reservoir upon each of a specified number of control pulses to a stepper motor, which moves a ball screw linear actuator with great precision on each control pulse. The reservoir is closed at the aerosol delivery position by a nozzle array, which is a thin sheet with myriad micro-via holes. The micro-vias are of the same dimensions and orientation, producing for a medical inhaler the desired micro-droplet volume, for example the volume of a 3-.mu.m diameter droplet from each micro-via, for each pulse.

  • Patent number: 6062496
    Abstract: An agricultural spray implement includes a plurality of removable valve/filter/nozzle cartridges. Each removable cartridge has a housing that retains a high speed solenoid valve and a spray nozzle. When the solenoid valve is open, an agricultural liquid (for example, herbicide) flows through the solenoid valve, through a chamber in the housing, and through the nozzle. To monitor cartridge operation and/or to detect cartridge failures (for example, a solenoid valve that is stuck open or closed or a nozzle that is clogged), a pressure sensor is provided that detects a pressure in the chamber. A chamber pressure that does not change when the solenoid valve is controlled to open and/or close is indicative of cartridge failure. Operation of each of the many spray cartridges of the agricultural spray implement is monitored from a single display.

  • Patent number: 6050504
    Abstract: A spray dispensing device is provided which can be used with non-pressurized containers. The device includes passageways for directing streams of air and, liquid where the liquid is broken up into droplets and emitted as a fine spray through an orifice. An annular air passageway is concentrically disposed around a liquid passageway, and the air is lead through air swirl passages, where the annular stream of air is given a rotary motion as the result of swirl vanes forming the air swirl passages. The velocity of air past a product passageway exit orifice also creates a Bernoulli effect which reduces pressure at that orifice, which acts to draw liquid to the spray orifice. The device may include a dip tube for the liquid which is provided with a check valve for retaining liquid at a high level in the dip tube after each spray cycle so that spraying is nearly instantaneous upon actuation.
