    Abstract: The use of green sand is eliminated by replacing green sand molds with all core sand assemblies that provide, during casting, both the internal and external surfaces of a casting, such as a cylinder head or engine block. In the process, a mold is formed from the same core sand that is used to form the core elements defining the internal passageways of the casting. A mold-core carrier is constructed with tapered sides that hold the assembled mold and core elements together during pouring of the molten iron alloy into the mold-core assembly and the cooling period to form the casting. Although the carrier sides can use a refractory liner, preferably the sides are made of replaceable sheet metal backed by an open structural framework to enhance cooling of the casting. After the casting is formed, the core sand from both the mold elements and the core elements is recovered, and may recycled and processed to form further mold elements or core elements or both.

    Abstract: Compositions and methods for the introduction of alloying compounds into a metal substrate using a laser energy source is disclosed. The compositions comprise a viscous fluid mixture of a powdered silicate mineral composite, a powdered metallic or semi-metallic compound and a water insoluble or slightly water soluble liquid component capable of supporting a dispersion of the powdered silicate mineral composite and the powdered metallic or semi-metallic compound therein. The composition may be sprayed in bulk onto large surface areas of a metal substrate in need of repair prior to laser irradiation.

    Abstract: A low rebound sports target useful in baseball pitching and fielding drills freely suspends horizontal and vertical elements for defining target zones wherein the elements are able to absorb the energy delivered by a high speed baseball tossed at the target and provide for rebounding of the ball from the target in a safe manner with regard to concerns by a player using the target. A target comprising vertical chains and horizontal rods freely suspended in a spaced relation to a frame holding the chain is described. Tubing sections provide shrouds for the chain and rods while also providing for easy adjustment of the target in creating various target zones. Further, a bag collects successful target hits while a netted backstop collects errant tosses by the player. A support used in suspending target elements further provides for suspending sports images useful for simulating realistic game conditions.

    Abstract: An m-dimensional memory with m-1 dimensional hyperplane access. Random acs memory (RAM) circuits are arranged in a plurality of groups for storing data words corresponding to vertices of an m-dimensional lattice. Each vertex of the lattice is defined by an m-tuple. The minimum number of RAM circuits required to realize the memory architecture of the present invention is based upon the size of the lattice and the distribution of the data words in memory is based upon the m-tuples used to define the lattice.

    Abstract: A method for relational database scheme design with the aid of a digital puter for a database having attributes A.sub.i, i=1 to n and relational schemes R.sub.j, j=1 to m. Each relational scheme R.sub.j is a non-empty subset of the attributes A.sub.i. The method detects any scheme that is non-acyclic in a simple manner that is easily adapted to a digital computer environment. The resulting relational database scheme design is thereby prevented from being non-acyclic.

    Abstract: The spark gap device disclosed herein comprises at least two sets of electrodes enclosed within a common chamber. A delay line is connected between successive sets of electrodes. An arc which develops across the first set of electrodes as a result of a voltage transient ionizes the gas in the chamber. The voltage transient is delayed by the time required to travel through the delay line. When the voltage transient arrives at the second set of electrodes, an arc develops in less time than was required at the first set of electrodes due to the fact that the gas in the chamber has been at least partially ionized.
