Abstract: Hard facing nickel-base alloys comprising 0.05 to 1.5% by weight of boron, 3 to 7% by weight of silicon, 7.5 to 35% by weight of chromium, 0.05 to 1.5% by weight of carbon, and if necessary, less than 30% by weight of iron and/or less than 5% by weight of tungsten, the balance being nickel, with the weight ratio of silicon to boron being equivalent to or exceeding 3.3. The alloys have a high degree of toughness, ductility, wear resistance and corrosion resistance, and no cracks occur in the hard facing layer. Addition of 0.1 to 3% by weight of the tin and/or 0.1 to 3% by weight of tantalum remarkably increases the corrosion resistance. The alloys can be used as a hard facing material to be applied to parts of various instruments, machines and plants.

Abstract: Under direction of a machine controller, an endless chain conveyor is incrementally passed by a plurality of loader heads. The loader heads receive a series of components taped on a reel supplied substrate, sever individual taped components from the supply, and load the individual taped components onto clip carriers of the endless conveyor, on command, in a preferred sequence. The clip carrier mounted components are then indexed past a cutter assembly for trimming the lengths of the leads and removing the substrate, and a positioning disc assembly for positioning the components in the clip carriers before being passed to a rotary transfer assembly. The rotary transfer assembly removes individual components from the conveyor and rotates to an unload position above a linear loader, which laterally transfers the components from the rotary transfer to an insert head assembly.

Abstract: A device for causing holders transporting objects to release the objects so as to place them at predetermined positions. The holders comprise a rotatable shaft, and a driving arm and an object-gripping arm both connected to the rotatable shaft and are carried by an endless conveyor so that the holders pick up an object at a first station and release the object at a second station. As the holders are conveyed from the first to the second station, the object-gripping arm gripping an object is kept parallel with the running direction of the conveyor. At the second station the driving arms of the holders are selectively moved into engagement with a device to turn the object gripping arm from the parallel position to a position perpendicular to the running direction of the conveyor and the object is released.

The seat includes a strap for encompassing a vertical support and a seat member of trapezoidal shape of a flexible material such as canvas. Webbing straps extend along the parallel bases of the trapezoidal seat and are joined at a distance from the seat sides to form a loop through which the strap passes for attachment to a vertical support.

Abstract: A burner for a bottom fired, ingot heating furnace producing faster and more even heating with lower fuel consumption is disclosed. The burner includes a plurality, preferably three, upstanding nozzles having nozzle ports directed at essentially a right angle to a radial line extending from the burner center. This orientation imparts a circular swirling action of the combustion gases which produces faster and more even heating of ingots contained within the furnace. The nozzle is arranged with a nozzle cap which shields the entire nozzle top from debris falling from the furnace roof resulting in a greatly extended service life.

Abstract: The device is adapted to break the circuit of the electrical system of the vehicle in the event of a tipping or overturning of the latter. The device comprises an elongated body containing two spaced-apart electrodes which are respectively connected to the positive terminal of the battery of the vehicle and to at least some of the electrical control or driving elements of the vehicle. The body contains an electrical conductive fluid in which the electrodes are immersed and is upwardly extended by two tubes which are perpendicular to the body and are interconnected in their upper part by a transfer pipe. A region of transition, located in the region of the connection of the body to the two tubes, is closed by a retarding diaphragm provided with a calibrated orifice. When the vehicle assumes an unusual inclination due to a tipping or overturning thereof, the fluid flows from the body into either of the tubes and thus breaks the circuit between the two electrodes.

Abstract: Normal line voltage, such as 115 volts AC available on a standard home or office receptacle (or single or three phase 230 volts AC), is surge protected and filtered prior to monitoring for voltage deviations outside of a voltage "window" such as 105-125 volts AC. Deviations outside of this voltage "window", are sensed and a deviation output signal is generated. The filtered AC supply and an auxiliary AC supply are selectively connected to the user equipment through a power distribution panel, with the selection being determined by the deviation output signal. By the method and apparatus of the invention, the computer equipment is supplied with primary input power from the utility company or the like as long as the voltage remains within this adjustable voltage window of 105-125 volts AC.
