Abstract: A door closer of the kind having a piston slidably mounted in a bore containing hydraulic fluid and dividing that bore into damping and reservoir chambers. Drive means is connected to the piston to respond to sliding movement of the piston and translate that into rotary motion for driving door connected linkage. The piston is spring influenced in a direction towards the damping chamber, and fluid pressurized by the piston tending to move in that direction bleeds from the damping chamber through an escape port which is controlled by a biased and movable closure member. Normally the closure member is biased into a rest position in which it blocks passage of fluid through the escape port, but it responds to fluid pressure in the damping chamber to move into an open position at which fluid can bleed through the escape port.

Abstract: An improved cutter for hot plastic strands is provided which uses an inwardly extruding frustoconical die and corresponding frustoncnical cutter rotating within the die.

Abstract: A process for controlled slow cooling of non-ferrous smelting slags, such as copper slags, for the recovery of the non-ferrous metals contained therein by subsequent crushing, milling and flotation operations is disclosed. The process comprises the steps of pouring the molten slag into a ladle, allowing the slag to slowly cool and solidify in the ladle at least to the point where a shell is formed which is strong enough to withstand dumping from the ladle, dumping the slag from the ladle in a single piece, allowing the dumped slag to cool until its center is substantially solidified, and breaking the dumped slag in small pieces for further cooling, crushing, milling and flotation operations. Alternatively, the top of the slag in the ladle may be water cooled while the slag is allowed to slowly cool in the ladle until its center is substantially solidified. The slag is then dumped and subsequently broken in small pieces.

Abstract: An electrical connector-switch for use underwater is in two halves. Each half includes a tubular casing to which respective external electrical leads are connected, for a power supply to one half and an output from the other half. Each half also includes a core. The two casings can be joined together and the two cores joined together end-to-end, so that the two cores can slide as one member within the two casings for switching purposes. Electrical contacts on one of the cores switchably interconnect the external leads of the two casings in one end position of the two cores. Seals between the cores and the casings keep the water out, both when the casings and cores are joined together and when they are not joined together, so that connection and disconnection and switching are all possible underwater.

Abstract: An apparatus for daylight shrimp fishing is disclosed. The apparatus includes a plurality of Otter trawls each having an electrode array and a pulse circuit. Each pulse circuit includes a capacitor which is discharged by a reversal of current to the capacitor which fires an SCR. A control unit located on the boat effects the discharging of the respective capacitors in a predetermined sequence to equalize the load on an alternating current generator. The electrode array has a plurality of electrodes which trail behind a bus extending between the trawl doors at a distance above the bottom. The electrodes are weighted to slide along the bottom and have an insulating material disposed above the conductor so that the electric current pulses are directed into the bottom rather than being dissipated upwardly into the water. The design of the bus and the electrode array is such as to insure uniform current density over the array.

Abstract: The invention is motion control apparatus for imparting random, erratic and unpredictable motion to a lure which is pulled through the water, a combination fish lure and motion control apparatus, a method of making the same and a method of establishing random, unpredictable motion for a fish lure. Universally coupled concave discs connected between the fishing line and the lure provide the erratic direction of travel and frequency of movement of natural bait, such as minnows or the like. By centrally pulling a first concave disc and edge connecting thereto a further centrally connected disc with bait edge coupled thereto, the random travel or directional change with attendant wiggling action is imparted to the fish bait. The unusual interconnection of the discs and their connections to the line and bait provide a continuously varying load center to impart the erratic motion.
