The fuse further includes first and second wire leads, the first wire lead being conductively connected to the first connection region and horizontally projecting away from the first connection region, the second wire lead being conductively connected to the second connection region and horizontally projecting away from the second connection region, for connecting the fuse to the remainder of the circuit.

Abstract: Magnetic integrated circuit structures exhibit desirable characteristics for purposes of realizing a magnetic semiconductor memory. In combination with a carrier-deflection-type magnetic field sensor, each of a variety of magnet structures realize a condition in which the magnetic field is substantially orthogonal to the direction of travel of carriers of a sense current, thereby achieving maximum sensitivity. In general, the magnetic structures are highly efficient and achieve a high degree of control of the magnetic field. As a result, a minimum-size device such as a MOS device suffices for purposes of sourcing a magnetizing current. By basing a magnetic memory cell on a single minimum-size MOS device, a small cell may be realized that compares favorably with a conventional DRAM or FLASH memory cell. The greater degree of control over the magnetic field afforded by the magnetic structures enables cross-coupling between cells in a memory array to be minimized.

Abstract: An exercise and posture correcting device comprising a slightly bowed strip of spring steel or other material having comparable flexing characteristics extends upwardly from the rearward portion of a broad width waist belt to which it is connected at one end to a padded contact member connected to a height adjustable extension sleeve slidably received on the strip at its upper end, such padded contact member at such upper end being positioned to bear against the wearer's back in the region between his shoulder blades. The padded contact member is biased toward and against the wearer's back by the strip of spring steel or other material. A rigid plate is secured to the broad width waist belt in back on which a tension adjusting ratchet assembly is mounted to increase or decrease pressure against the user's back as desired.

Abstract: A powered shrimp deveining assembly includes a motor coupled to an output and a secondary shaft both housed in a removable enclosure, the output shaft and the secondary shaft extending through an adapter to turn a cutter against the rotation of a pair of guide disks. The adapter is provided with a boss in which one end of a bell crank is engaged, the other end of the bell crank extends in a threaded projection through an arcuate slot formed in a cover that is mounted on the adapter to shield the cutting mechanism. An idler roller on the bell crank is thus pivotally spaced from the guide disks to direct shrimp bodies against the cutter, the same bell crank fixing mechanism also retaining the cover in place.

Abstract: A simple, strong, and durable animal leash, comprising two elements. The first element is a lead formed of strap material. The second element is a snap link, which is a relatively large link made of aluminum, one side of which is a gate which can pivot inward so as to open the snap link and permit its attachment to a collar or halter. The large open area of the snap link makes it a versatile attachment device which is easy to manipulate. The leash may be attached and used in a multiplicity of ways, and the various sizes of the leash span a wide spectrum of uses.

Abstract: A simple, strong, and durable animal leash is disclosed, comprising two elements. The first element is a lead of woven nylon, with a loop formed in each end, the two loops being equal in size and appropriate for grasping by a person's hand. The second element is a carabiner, which is a relatively large link made of aluminum, one side of which is a gate which can pivot inward so as to open the carabiner and permit its attachment to one or both of the loops and a collar, halter, or harness, thereby providing for simple and convenient attachment of the leash to the animal in a multiplicity of ways.

Abstract: A variable orifice gas modulating valve for use with an atmospheric Bunsen-type burner is disclosed. The variable orifice valve discharges a jet of fuel directly into the burner mixing tube and modulates the gas flow to the burner by changing the cross-sectional area of the gas jet. This is accomplished by a thin moveable sheet interposed between a valve body and a cap, through which pass the upstream and downstream portions of a short gas discharge passageway. The sheet has a hole which is positioned relative to the axis of the gas discharge passageway so as to produce a discharge orifice of variable size. The gas jet has the same velocity at all inputs, and flow rate variation is manifested by variation in the jet cross-sectional flow area.

Abstract: A semi-instantaneous water heater is disclosed. The water heater generates domestic hot water by transferring heat from the circulating fluid of a modulating boiler. It is particularly suited for use in a combination system, which provides both space and water heating. The semi-instantaneous design incorporates a small cylindrical tank containing stored hot water and an immersed heat exchanger. The heat exchanger is a helical coil disposed in the annular space between two metal sheets that have been rolled into cylinders. The coil conveys heated fluid from the boiler. Heat from the coil is transferred to the water, which is admitted to the tank via the helical passageway formed by the two sheets and the inter-coil space of the helix. The heat exchanger effectively transfers heat by forced convection at a high rate when required by a high flowrate of water. Its disposition in the tank also permits good heat transfer by free convection to quiescent water in the tank when this heating mode is required.

Abstract: A gas modulating valve for use with a gas burner is disclosed. Two variations of the valve are disclosed: the direct-discharge variation discharges a gas jet directly into the mixing tube of a gas burner, and the in-line variation meters the gas flow from the supply line to a gas manifold, which in turn terminates in one or more fixed orifices which discharge to the burner mixing tube or tubes. With respect to the moving parts, the two variations are identical. In both variations, the modulation of the gas flow is achieved by a thin moveable slide sandwiched in a planar space between two fixed valve body members, through which pass the upstream and downstream portions of a short gas discharge passageway. The slide has a hole which is positioned relative to the axis of the gas discharge passageway so as to produce a discharge orifice of variable size. The valve is sealed against leakage by face seals effected with o-rings. The valve actuator is a stepper motor which is controlled by an electronic controller.

Abstract: A sheet metal atmospheric gas burner capable of a 5:1 turndown ratio is disclosed. The burner is intended for application in instantaneous water heaters and other gas burning appliances having high input modulation requirements. It has a hollow cylindrical burner head fabricated of sheet metal, a single mixer tube, and slotted ports arranged on the vertically-oriented cylinder sidewall. The unique features of the burner are the tabbed slotted port design, the use of fins adjacent to port rows to eliminate flame blowoff and assure quiet burner operation, and the arrangement of ports on the burner head to simultaneously provide good secondary aeration at all inputs and flame carry to all ports at all inputs. The advantages of the burner are its simplicity, low cost, and ease of manufacture, relative to its demanding performance requirements.

Abstract: An oyster shell separator deploys a conical, helically ridged, powered point driven in rotation by an electrical motor within a wedge shaped housing. The conical point draws the shells onto a flanged collar selected in dimension to fully separate the shells. From the collar the shell halves are passed along the sides of the housing for collection and sorting.

Abstract: Acetylthio amides and esters were prepared by the free radical addition of thiolacetic acid to the terminal and nonterminal double bonds of N-substituted fatty amides and fatty esters. The free radical additions of the thiolacetic acid to the unsaturated compounds were initiated by irradiation using cobalt-60. The process using irradiation with cobalt-60 was also used to bring about the addition of bromotrichloromethane to N-substituted fatty amides and fatty esters to produce halogen-containing amides and esters. These new sulfur or halogen-containing compounds were found to have antimicrobial activity and to possess properties making them useful as antimicrobial agents.
