  • Patent number: 4212071
    Abstract: The invention relates to the operation of a compacting machine. At least certain of the data relating to the operating parameters are stored in a memory; the length to be traversed L, the advance length la, the number of passes nP or round-trips to be executed before changing track, and the number of tracks N. The length traversed and the direction of operation are continuously detected, and signals are emitted to control an operation or preferably to inform the driver of the operation to be carried out. The lengths traversed during braking or change in track are taken into account each time in the determination of the length to be traversed. The signals can be given by arrows and fixed or blinking lights. Old or new compaction machines can be driven by the method using this device.

  • Patent number: 4192113
    Abstract: A covering and sealing assembly for concealing and sealing the gap between a pair of edge adjoining wall panels which are disposed at an angle to each other, such as at a corner. The assembly includes an exterior trim piece, a supporting member for the exterior trim piece, fastening means to tighten the supporting and clamping members together to squeeze the edges of the panels at the corner and to thus provide a structural tie therebetween, and an interior trim piece which snaps over the free vertical edges of the clamping member and hides the fastening means and the clamping member. The structural tie between the two corner panels is effected by the squeezing action of the legs of the supporting member and of the clamping member upon the faces of the adjoining wall panels at the points of contact between the faces and the supporting and clamping members.

  • Patent number: 4190534
    Abstract: A waste water filtration and sludge removal system for filtering and removing sludge materials suspended in water resulting from steel pickling and cleaning operations and the like. The system includes a trough-like filtering tank having weep holes along the lower edge draining into an inclined channel for capturing filtered water for reuse, and also includes a multiple layer filter bed containing an upper layer of fine jagged surfaced particles for capturing filtered sludge. The sludge layer deposited on the surface of the upper filter layer is periodically moved by means of an adjustable screed blade toward an elevated discharge station for removal from the tank without significantly disturbing the filter bed. The screed blade may be automatically raised out of contact with the sludge layer when operated in the reverse direction.

  • Patent number: 4169734
    Abstract: A composition which improves the hot strength of chemically bonded refractory shapes such as brick. The composition is comprised of refractory brickmaking size graded magnesia and chrome ore grain in a weight ratio between 90/10 and 30/70. The major portion of chrome ore grains must be smaller than 28 mesh; preferably, therefore, such chrome ore grains should be of a size that will pass 28 mesh screens and stay on 200 mesh screens. The lime (CaO) silica (SiO.sub.2) ratio is in the range of 0.2 to 2.5 depending on the total silica content of the system. Such silica content should never be more than about 2.5% by weight on the basis of an oxide analysis of the whole mix, but it may be as low as about 0.5% on the same basis. When the silica content is low (0.5 to 1.3%), the lime/silica ratio may be either high (1.8 to 2.5) or low (0.2 to 1.0). When, however, the silica content is high (1.4 to 2.5%), the lime/silica ratio must be low (0.2 to 1.0).

  • Patent number: 4158900
    Abstract: A bottom board for beehives for controlling the direction of travel of arriving and departing bees. Arriving bees are guided directly to the honeycomb frames by means of an upwardly inclined landing deck, which also serves to separate arriving bees from departing bees leaving the hive by means of a descending departure ramp located beneath the landing deck, thus insuring an uncongested one-way traffic pattern. A slotted false bottom located in the bottom board also serves to control the direction of travel of arriving and departing bees.

  • Patent number: 4156885
    Abstract: An automatic current overload protection circuit for electrostatic precipitator power supplies of the type utilizing a ferroresonant transformer. A low voltage tertiary winding in association with the transformer provides an output voltage to a sensing circuit for inhibiting current flow into the primary of the transformer when the tertiary voltage falls below a predetermined threshold. Another output voltage developed in association with the high voltage secondary winding of the transformer is also utilized to independently inhibit current flow into the primary of the transformer when the secondary voltage falls below a predetermined threshold. A time delay may be provided to permit operation of the overload protection circuit only in the event of a sustained overload current condition.
