Abstract: The invention concerns a process for washing fibrous materials, skins, textile materials or the like using an aqueous, surfactant containing washing liquid obtained by adding washing agents to water. The minimal dispensed amounts as determined in subsequent washing tests are always obtained automatically, without the cleaning power and the cleaning efficiency being reduced to unacceptable levels. To this end, the surface tension of the washing liquid is measured during the washing process using a tensiometer. The actual washing agent concentration is derived from these measured values and an initial concentration is derived from the quantity of washing agent added. The detergency is calculated from this initial concentration. The addition of a washing agent is discontinued when no further increase occurs in the detergency. The invention also concerns a device for carrying out the process. The device has capillaries connected to constant gas flow sources and immersed to the same depth in the washing liquid.

Abstract: A self-propelled submersible suction cleaner as used to clean the surfaces of a swimming pool transfers a vibratory movement of an oscillator located within the flow path of a suction chamber for propulsion over the submerged surface of the pool. This vibratory movement of the oscillator is also converted to a unidirectional rotational motion used in conjunction with a gear train to cause the cleaner to rotate through at least a 90 angle allowing the cleaner to improve on the random path taken by the cleaner and to maneuver away from obstacles such as pool steps potentially stopping the cleaner movement. The cleaner includes a elevation limiter that keeps the suction chamber submerged as the cleaner climbs a vertical wall and attempts to rise above the water level in the pool. A pressure relief valve eliminates the concern over debris blocking the suction and causing potential damage to the pool pump and motor.

Abstract: A vacuum cleaner rotates a propeller fan by its suction force. The propeller fan rotates a rotor of a d.c. electric energy generator so as to generate electrical energy, and a d.c. voltage corresponding to the suction force is obtained by the generation. The vacuum cleaner employs the d.c. voltage as an operating voltage for a dust sensor and the peripheral circuitry thereof. The vacuum cleaner compares the d.c. voltage with a constant voltage output from a constant-voltage circuit by a comparing circuitry. The vacuum cleaner lowers the gain of an amplifying circuitry based upon a signal output from the comparing circuitry in correspondance to an increasing of the d.c. voltage obtained by the d.c. electric energy generator. The amplifying circuitry amplifies output of the dust sensor. The vacuum cleaner automatically determines detection sensitivity to be a proper sensitivity. The detection sensitivity is the sensitivity for detecting dust, based upon an output from the dust sensor.

Abstract: A rapid deployment system for recovering oil from beaches includes an articulated vehicle for propelling and suspending a vacuum head above a beach or the like. A selected area of the beach is irrigated with sufficient quantities of water to saturate the selected area. Oil deposited on the beach is driven to the surface.

In the vacuum head, the velocity of the air flow is suddenly and significantly reduced above a fluid sump wherein entrained oil and water droplets fall into a sump for processing outside of the vacuum head. A metal auger can be provided within the vacuum head to pump oil from pools and separate entrained oil droplets from the high velocity air flow. A special terrain vehicle which propels and supports the vacuum head is modular and can be transported by helicopter with the entire system.

Abstract: The method comprises decomposing an original resonator within a network into a pair of series connected resonators to add an additional connecting electrode to the network. The pair of resonators are series connected by a shared electrode. To preserve the original electrical characteristics of the network, the composite characteristics of the series connected resonators are chosen to match those of the original resonator. With this method, the additional electrode is placed on a surface of the piezoelectric material opposing the surface to which the shared electrode is mounted. The method allows for the addition of an electrode to a piezoelectric resonator-based network so that the electrodes which connect the network to other circuitry may be placed where desired. This may be on the upper surface of the piezoelectric material for connection to discrete components or on the lower, buried surface for connection to buried layers of an adjacent integrated circuit.
