  • Patent number: 6077359
    Abstract: A method of treatment of printed circuit boards or conductor films with a chemical, electrolytic, or rinsing treatment liquid, and to a device for carrying out the method, where the printed circuit boards or conductor films are transported in a horizontal direction by transport means, In order to accelerate these processes, the surfaces of the printed circuit boards or conductor films must be exposed to a macroflow in order to apply active treatment liquid. Furthermore, the micromaterial exchange into the diffusion layer must be reinforced. This exchange is brought about by the use of hydrodynamically acting cavitation generators, which form cavitation bubbles in the liquid jets. The treatment liquid is set into an eddy current movement in the generators because the treatment liquid is applied at high pressure in a circuit through the nozzles generating the cavitation bubbles, and is conveyed to the surface in a large quantity.

  • Patent number: 6058556
    Abstract: A movable-head cloth-cutter bristle block cleaner for cleaning a conveyor-type bristle bed trained between the rotatable end units of a cloth cutter. The cleaner has a movable head attached to a cable cylinder which is coupled to the frame of the cloth cutter. The head moves substantially the entire width of the bristle bed. In one embodiment, nozzles are placed in several rows on the head and are positioned so that they extend into the bristles of the bristle bed. The movable head is coupled to a supply of compressed air. When the bristle bed moves, high volume, high pressure air is delivered to the head and then shoots out of the nozzles. The jetting action of the gas leaving the nozzles effects removal of debris contained within the bed. Because the cleaning head moves across the entire width of the bristle bed, fewer nozzles are needed to clean the bristle bed. This allows the air pressure coming out of the nozzles to be delivered at a high level.

The drive can be controlled by a control device that receives a target distance as input value and an actual distance between the nozzle device and the surface of the semi-finished product detected by means of a distance sensor. The control device supplies an output signal via a signal line to the drive for resetting any deviation to zero. Hence, the nozzle device is always kept at a desired target distance even if humps such as bulgings occur on the surface of the semi-finished product.

  • Patent number: 5976299
    Abstract: A method for making a non-peelable, sterilizable receptacle having a low particulate count for receiving articles for storage in pharmaceutical intermediate processing. This method involves providing a continuous first web of polyolefin film, providing a continuous second porous web of spun-bonded polyolefin film. The webs are advanced through cleaning processes that include an anti-static device, an ultrasonic vibrating device and a vacuum device. The two clean webs are then brought together and passed into the heat sealing section. The webs are heated welded together by forming continuous seams on the webs to form an open pouch. The seams are made by applying opposing platens at a pressure between about 30 to about 40 psi to both the webs and a heat welding element at a temperature of about to about F. against only the first web. This causes the first web to melt into the pores of the second web.

  • Patent number: 5603775
    Abstract: Cleaning apparatus, and a method of utilization of the apparatus, cleans an object with a moving surface, such as a roll. The cleaning apparatus includes a nozzle head with a suction nozzle and a jet nozzle for emitting a liquid jet towards the roll. A sub-pressure is maintained in a chamber of the suction nozzle in order to evacuate liquid and released impurities with the aid of air flowing through a gap between the roll and the orifice edge. The jet nozzle is spaced from the inside of the suction nozzle and at the center of the suction nozzle to form a circumferential passage, the passage communicating with an evacuation pipe. The nozzle head also includes a structure to supply compressed air into the chamber through the gap in order to encounter and carry with it toward the passage liquid and impurities, cooperating with the suction effect maintained in the chamber and the evacuation pipe. The compressed air also has the advantage of drying the roll treated with liquid.
