Title: Hardfacing composition of nickel-bonded sintered  chromium carbide particles and tools hardfaced  thereof
Inventor: SMITH THOMAS J
IPC: B24D3/06
Filed: 1979-06-18
Granted: 1981-12-29
Abstract: Abstract A mining or drilling tool which has a region subject to excessive wear is hardfaced on such region with sintered chromium carbide particles metallurgi-cally bonded on the tool by a steel matrix wich is alloyed with the particles at the interfaces there-between.  The particles are in a size range of 10 to 60 mesh and are present in an amount for effective abrasion resistance.  The particles are comprised of grains of chromium carbide having an average size in the range of 0.5 to 25 microns disposed in a binder comprising a major portion of nickel.  Minor portions of grain growth inhibitors, particularly, titanium carbide and molybdenum carbide, are preferably compo-nents of the carbide particles so as to inhibit growth of the chromium carbide grains to be such that such grains have an average size in the range of 0.5 to 15 microns.  The particles are preferably coated, prior to being applied as the hardfacing, with one or more materials such as ferrosilicon, ferromanganese, ferromolybdenum, nichrome and others identified below, to limit the alloying of the particle per se with a steel matrix, to improve the matrix, and to improve the welding characteristics of the hardfacing materials.  There is also provided material com-prising discrete particles as above described which are useful in forming the hardfacing material on the tool.

Abstract: ABSTRACT OF THE DISCLOSURE       In a steam iron with the water tank above an electrically heated soleplate with steam apertures, a primary steam generator is disposed in the soleplate and fed from the tank by a metering water valve for steam generation.  A cover plate over the soleplate forms distributing passages connecting the primary generator with the apertures and a separate surge generator is provided and fed by a surge valve for intermittent steam generation.  A duct connects the surge generator in upstream flow series relation so surge steam flows through the duct into the primary generator and then through the distributing passages to the apertures for a surge of steam.  To this general arrangement, an improvement is provided comprising a nozzle means forming the exit from the duct and discharging centrally of the primary generator whereby the nozzle increases the surge steam velocity into the primary generator to scrub the generator before entering the distribution passages to the soleplate apertures.

Abstract: SLICE CONTROL CIRCUIT FOR    A SLICING MACHINE     Abstract of the Disclosure A slice control circuit senses the angular position of a blade employed to slice products, such as bacon or cheese.  The position information is utilized to correctly position the product relative to the blade to obtain uniform slices.  When slicing is interrupted the product is withdrawn from the blade to prevent nonuniform slices.  When slicing is resumed the circuit inserts the product into the blade path at the correct point of blade rota-tion to resume production of uniform slices.  A voltage controlled oscillator maintains the product movement in synchronism with blade velocity.

Abstract: PROCESS AND APPARATUS FOR COMMERCIAL FARMING OF MARINE AND FRESHWATER HYDROPHYTES ABSTRACT OF THE DISCLOSURE The disclosure relates to the propagation and cultivation of freshwater and marine plants. These freshwater or marine plants are found naturally in underwater, floating or air-water interface habitats where sufficient illumination, nutrients and moisture are available to sustain life. A process is disclosed in which fresh-water and marine macrophytes are cultivated in a water charged atmosphere, rather than in their native freshwater or marine en-viornments, under precise control of such critical growing con-ditions as light, temperature, nutrient supply and disease control. Carbon dioxide, a plant nutrient is introduced into the atmosphere or into the water while other nutrients are provided through the use of controlled mists or sprays arranged to maintain a film of nutrient containing freshwater or seawater on the growing plants. Natural waters may be periodically enriched with organic or in-organic nutrients. Significant improvement in harvest efficiency is realized by water charged atmospheric culturing of the marine and freshwater macrophytes, such that harvesting of the hydrophyte on a commercial basis is feasible.

Granted: 1982-05-25
Abstract: ABSTRACT OF THE DISCLOSURE      The end connector and coupling assembly disclosed herein is for a shielded cable having a flexible conduit, but also is compatible with unshielded cables.  An annular connector body houses an insulator holding a plurality of arranged terminal contacts to which the cable conductors are connected. An annular adaptor fitting surrounds the conductors and has one tubular end sized to telescopically receive and be mechanically secured to the cable conduit, and has an opposite tubular end provided with a conically tapered inner bore face diverging in a direction away from the secured cable.  A resilient grommet is fitted over the cable conductors and is within the adaptor fitting bore.  A conventional locking nut cooperates with an exterior shoulder on the adaptor fitting in order to draw the adaptor fitting snug against the annular body thereby compressing the grommet between the adaptor fitting, the annular body, the insulator and the conductors.  A coupling sleeve can cooperate with an exterior shoulder on the annular body to lock the connector assembly mechanically to another connector or terminal board.

Abstract: ABSTRACT          Portions of a doped silicon body 22 are covered with an oxide dielectric 26 leaving the active areas 25 on the silicon body exposed. A polysilicon layer 28 having a predetermined resistance characteristic is formed over the entire wafer surface followed by a layer of silicon nitride 30.  Selected portions of the silicon nitride layer 30 are removed with the nitride remaining over the source/drain regions 36 of the active area and the locations of first level conductor runs 32. The exposed polysilicon 28 is converted to an oxide and the silicon nitride 30, covering the source/drain regions 36 and the first level conductor runs, is removed.  The exposed polysilicon is doped forming source/drain diffusions 46 and first level conductors 32.  An oxide dielectric 52 is formed over the wafer 20 and removed from the gate areas 56 followed by the formation of a thin gate dielectric 54.  Finally the oxide 52 is removed at the interconnect work sites and second level conductors 58, 60 are formed.  If desired, resistors are formed by allowing the nitride masking layer 30 to remain over selected portions of the polysilicon during the doping of the source/drain areas and first level conductors.
