  • Patent number: 4157925
    Abstract: A process for producing electromagnetic silicon steel having a cube-on-edge orientation. The process includes the steps of: preparing a melt of silicon steel containing from 0.02 to 0.06% carbon, from 0.015 to 0.15% manganese, from 0.005 to 0.05% of material from the group consisting of sulfur and selenium, from 0.0006 to 0.0080% boron, up to 0.0100% nitrogen, up to 1.0% copper, less than 0.005% antimony, less than 0.009% aluminum and from 2.5 to 4.0% silicon; casting; hot rolling; cold rolling; decarburizing; applying a refractory oxide base coating; and final texture annealing. During final texture annealing the steel is heated from a temperature of 1700.degree. F. to a temperature of 1900.degree. F. at an average rate of less than 30.degree. F. per hour, and subsequently maintained at a temperature in excess of 2000.degree. F. for a period of time sufficient to effect a purification of the steel.

  • Patent number: 4156053
    Abstract: A process for preparing metal having a substantially uniform dispersion of hard filler particles. The process includes the steps of: admixing particles of a first metallic component with oxide particles having a negative free energy of formation at 1000.degree. C. of at least as great as that of aluminum oxide, and with a dissimilar second metallic component; and of milling for a period of time sufficient to produce powder characterized by a substantially uniform dispersion of hard filler particles and heterogeneous agglomerations of at least two metallic components. The first metallic component is from the group consisting of nickel, cobalt, iron and alloys thereof. Both the first and the second metallic component have an average particle size of less than 10 microns.

  • Patent number: 4152179
    Abstract: A method for producing a soft magnetic material consisting essentially of up to 0.05% carbon, up to 1.0% manganese, up to 0.5% sulfur, up to 0.5% silicon, from 0.5 to 1.5% phosphorus, balance iron and residuals. The method comprises the steps of: blending iron powder and phosphorus-bearing powder into a mixture containing from 0.5 to 1.5% phosphorus; pressing the blended mixture; and sintering the mixture in a non-oxidizing atmosphere at a temperature and for a period of time sufficient to produce a density of at least 7 grams per cubic centimeter. The sintering temperature is at least 2200.degree. F. The soft magnetic material is characterized by a magnetizing force to reach 10 kilogauss of no more than 2.0 oersteds, and a coercive force from 10 kilogauss of no more than 0.9 oersted.

  • Patent number: 4151772
    Abstract: A machine for continuously conveying slabs of meat, such as bacon, to a revolving blade and slicing same into accurate, weight controlled groupings, preferably by control of the conveying system. The machine has a plurality of longitudinally spaced, generally transversely extending rollers and a plurality of finger means mounted on the front roller that is adjacent to the blade, but rearward of the front roller, to apply downward and rearward forces to the conveyor supported slab to positively control the slab travel to, and particularly adjacent, the blade.

  • Patent number: 4149222
    Abstract: A bed light safety apparatus which includes a normally wall mounted lighting fixture. The upper rearward edge of the fixture is pivotally mounted to a plate adapted for attachment to a wall. One embodiment of the apparatus includes a switch carried by the fixture. When used in conjunction with a hospital bed or the like which is power operated to a raised position, the switch is made a part of the electrical circuit for the bed drive means. In the event equipment carried by the bed strikes the fixture on raising of the bed, the consequent pivotal movement of the fixture causes the switch to open the circuit to the bed drive means and halt further raising of the bed. In other embodiments the safety apparatus may include visual or auditory alarms actuable by a switch in the fixture.

  • Patent number: 4138273
    Abstract: A strip is continuously passed through a molten salt bath in a main tank having a central longitudinal baffle providing passageways at each end thereof. A sink guide roll is provided for the strip at the exit half of the tank. A heating tank is located along one longitudinal side of the main tank at the entry end thereof and has front and rear connecting openings with the main tank. An agitator is positioned at the front end of the heating tank. A forward tank section located along the other side of the tank has a bottom opening connecting therewith. An intermediate tank section has upper and lower compartments, the upper compartment serving as a sludge settling basin. A rear tank section has an agitator therein and is connected to the forward tank section through the lower compartment. Small openings adjacent the top of the upper compartment open into the main tank and to the rear tank section.

  • Patent number: 4126177
    Abstract: A heat exchanger for rapidly heating or cooling materials such as fluids containing fragile, discrete particles of varying sizes without substantial damage to the particles. The exchanger has inner and outer heat transfer surfaces that define an elongated annulus. Located in the annulus is a pair of opposed, spiral, inner and outer ribs which do not span the annulus and which, upon rotation, move the material toward the exchanger inlet against the flow therefrom which overflows the ribs and moves from rib to rib and to the outlet. Scraper blades associated with the ribs, scrape the exchanger inner and outer surfaces.

  • Patent number: 4126777
    Abstract: A control circuit is provided for a microwave oven in which a crystal rectifier is responsive to variations in the level of the electromagnetic field within the oven cavity when items of different energy absorption or reflection characteristics are placed in the oven. The electric current developed by the crystal is employed to generate a ramp type electrical signal which is compared with a fixed reference voltage to control the termination of microwave power to the oven. Compensation for the nonlinear relationship between crystal current and the level of the electromagnetic field within the oven is provided. In addition, compensation for the initial temperature of the food item which is placed in the oven is provided.
