  • Patent number: 5333724
    Abstract: A cleaning apparatus for cleaning of food-processing conveyor belts, particularly of metal conveyor belts used to convey bakery goods through baking ovens, includes an equipment carrier including pumping and vacuum equipment; mounts for mounting frame members carrying cleaning heads including cleaning and rinsing solution applicators, a brush, a splash shield, and vacuum heads; and, interconnections for connecting carrier-supported equipment to cleaning heads. In operation, cleaning heads are mounted to the mounts and are connected to the carrier-supported equipment; and, the conveyor belt is sprayed and soaked with a cleaning solution and left for a time before having the solution together with debris and residual and carbonized matter rinsed off and vacuumed up. Brushes brush the conveyor during cleaning and rinsing.

  • Patent number: 4539078
    Abstract: A method of, and apparatus for, making a synthetic breakwater involves the steps of arranging flat, approximately parallel electrodes (20 and 22) which are approximately coextensive with one another, so that they are spaced from one another by electrically insulative materials (10) with a gap of from 3 cm to 27 cm. An electrical potential is applied across these electrodes to cause a current density flowing between the electrodes of not greater than 0.1 milliamps (ma) per cm.sup.2. In the preferred embodiment, the electrodes are spaced approximately 5 cm apart and a voltage of around 3 volts is applied thereacross. The flat cathode is of expanded electrically-conductive metal, with the anode being constructed of two materials, one of them being an outer casing (30) of lead.
