Abstract: Abstract of the Disclosure A method of forming combination CMOS field effect transistors optionally with a charge transfer device in a single substrate.  Different resistivities in the P type wells of the substrate are formed by a combination of masks; a high energy low dosage ion implantation of impurity passes through one mask but not the other, and a low energy high dosage ion implantation of the impurity is stopped by both masks.  A significant number of fabrication steps is thus saved, and the devices so fabricated are threshold and field voltage compatible.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention provides a process and apparatus for manufacturing yarn products comprised of an. inner core of fibers and an outer layer of fibers.   In the process, first fibers have a pre-twist imparted thereto to form a strand which becomes the inner core of the yarn and the pre-twist is retained by passing the yarn between two pinch points.   While between the two pinch points, second fibers are juxtaposed to the strand and any untwisting tendency by the inner strand will tend to twist the outer layer of fibers.   Optionally, the yarn may undergo a further twisting operation while between the two pinch points after the second fibers have been deposited.

ABSTRACT OF THE DISCLOSURE     Method for producing aluminosilicates their use as catalysts and catalytic compositions containing them Crystalline aluminosilicates containing an organic nitrogen cation are prepared by mixing a source of silica, a source of alumina, a source of alkali metal, water and one or more substituted neopentyl-amines having the formula:-  wherein R2 is H, OH or NH2 and R1 is a C1 to C6 alkyl group, and maintaining the mixture under conditions of elevated temperature and pressure, typically in the range from 80 to 210°C and 70 to 400 psig, for a time sufficient to effect formation of the aluminosilicate, typically not less than 4 hours.  The molar ratio of silica to alumina in the initial mixture is suitably in the range from 10:1 to 150:1 and the amounts of alkali metal and neopentylamine are suitably in the range from 50 to 0.02 moles per mole equivalent of total silica and alumina in the respective sources.  Depending on the ratio of silica to alumina in the initial mixture crystalline aluminosilicates having a mordenite structure or a ZSM-5 type zeolite structure or mixtures thereof may be prepared.  Mordenites having a silica to alumina ratio greater than 10:1 and an alkali metal content less than 0.15% by weight can be prepared directly by crystallisation without any post- crystallisation treatment.

Abstract: TITLE:  LUMBER STACKING APPARATUS                 Abstract of the Disclosure A lumber stacking apparatus for successively plac-ing layers of boards one on another to form a vertical stack, and for automatically placing stickers between successive lay-ers of boards to vertically separate the layers within the stack.  The successive layers of boards are formed along a layer support surface adjacent the stack.  A forked arm assem-bly is raised to lift the formed layer from the layer support and carry the lifted layer to the stack and deposit the layer on the stack.  The stickers are initially moved transverse to the movement of the fork arms to selected sticker positions.  The stickers are then lifted up and over sticker supports pro-vided on the sides of the fork arms.  As the fork arms are raised to lift a layer of boards from the layer support sur-face, the sticker supports simultaneously lift a layer of stickers against the bottom side of the board layer.  Both layers are then moved outward over the stack, lowered, and stripped from the fork arms and sticker supports onto the stack as the fork arms are drawn back past stripping surfaces.          The stripping surfaces are vertically movable in response to movement of the fork arms between positions clear of the layer to allow outward movement of the layers over the stack, and positions intersecting the paths of the layers as the fork arms are retracted.

Abstract: ENERGY SAVING REFRIGERATION SYSTEM     Abstract of the Disclosure A refrigeration system having an increased efficiency of operation and reduction in power consumption.  By subcooling the liquid refrigerant emitted from the remote condenser, the efficiency of operation of the compressor of the refrigeration system can be substantially increased.  The particular type of refrigeration system of concern generally includes a compressor for compressing a gaseous refrigerant, a condenser for condensing the gaseous refrigerant and subcooling the liquid refrigerant, a receiver for receiving the liquid and a plurality of display cases having evaporators for evaporating the liquid refrigerant.          The gaseous refrigerant passing through the condenser is first condensed into a liquid at a condensing temperature of approxi-mately 10 to 25°F above a preselected cooling temperature.  The condensed liquid is then subcooled to the preselected cooling temperature which should be preferably either approximately 50°F or the temperature of the ambient atmosphere surrounding the condenser, whichever is higher.

Inventor: KROGSRUD HARALD
IPC: F27B9/38
Filed: 1980-10-22
Granted: 1984-04-10
Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for feeding charge to a covered electric smelting furnace is disclosed.  The apparatus is substantially gas-tight and includes a charging chute which is connected to a housing so as to feed charge into an opening on one side of the housing.  The housing includes a discharge opening in the bottom thereof in communication with the interior of the furnace.  The housing has a cylindrical lower portion which receives a rotatable hollow cylinder in a nesting fashion.  The cylinder has an opening for receiving charge from the chute and is rotatable so as to bring that opening into alignment with the discharge opening in the bottom of the housing so as to discharge charge into the furnace.  The nesting of the cylinder in the cylindrical portion of the housing forms a substantially gas-tight seal.  Furthermore, the cylinder is cradled in the cylindrical portion without being axially mounted and is thus freely moveable away from the cylindrical portion of the housing.  Thus, the cylinder may ride up over a portion of charge which might become wedged between the cylinder and the cylindrical portion without seriously affecting the gas-tight seal.

Abstract: BRUSHLESS EXCITER ROTOR MOUNTING A brushless exciter rotor mounting of a sleeveless design directed to a rotor core which is mounted on the shaft of an AC generator so that the rotor core can be rotated by the generator to provide direct current to the generator. The shaft has a stepped construction providing a larger diameter of the shaft at the inner end portion and a lesser diameter portion of the shaft extending outwardly therefrom. The rotor core has a slightly larger inner diameter than the lesser diameter portion of the shaft for a predetermined length to provide a radial clearance therebetween. At the inner end of the shaft the rotor core pilots to the larger diameter end portion of the shaft and at the outer end portion of the shaft a standoff casting pilots to the shaft. The shaft is keyed to the rotor core to prevent rotation of the shaft within the rotor core. Capscrews secure the rotor core to the standoff casting at the outer end of the assembly and the standoff casting is in turn secured to the shaft through a capscrew and belleville washer which seats the shaft within the standoff casting.
