Abstract: ABSTRACT OF THE DISCLOSURE      A magnetically enhanced sputtering device including magnet means for establishing a magnetic field where the lines of force thereof extend over and may pass through the cathode sputtering surface at one predetermined area thereof.  Preferably, the majority of the lines of force passing through said predeter-mined area of the sputtering surface are inclined at angles of 45° or less with respect to the surface. The magnet means may be disposed on the side of the cathode opposite the sputtering surface where the flux therein extends substantially parallel to the sputtering surface.    Means for shaping the magnetic field at least along the direction of the lines of force may also be provided where the field shaping means may render the lines of force more parallel to the sputtering surface to thereby enhance uniformity of eros-ion of the sputtering surface at least in the direction of the lines of force and/or the field shaping may cause the lines of force to be substantially perpendicular to an edge of the sput-tering surface to thereby substantially limit erosion of the sputtering surface beyond the edge.    The magnet means may cause a closed loop configuration of the lines of force where the closed loop configuration has at least some non-linear portions.  Preferably flexible magnetic means may be employed for enhancing the uniformity of the mag-netic field along the non-linear portions.

Title: Random access bubble memory with unified read/write  cycle
Inventor: VAN VOORHIS DAVID C

Granted: 1982-10-05
Abstract: RANDOM ACCESS BUBBLE MEMORY WITH UNIFIED READ/WRITE CYCLE       ABSTRACT      A random access bubble memory directs a plurality of continuous streams of bubbles toward a plurality of storage loops. A write decoder selects one continuous stream of bubbles.  An annihilator then transforms this one continuous stream of bubbles into the desired data pattern which is then stored in a selected loop.  While the data pattern is being formed, a read decoder directs the data which had been stored in the selected loop to a bubble detector.  This memory has a unified read/write cycle which permits intermixed read and write, read/modify/write, and swap operations.  This bubble memory allows a user to remove power abruptly during a read/write cycle without returning a partially processed block to its storage loop and without saving the identity of the block. In a preferred embodiment, the read and write decoders are operated simultaneously by identical control currents.

Abstract: CIRCULATORY WATER HEATER                    ABSTRACT OF THE DISCLOSURE            A circulatory water heater utilizes a submersible pulsating heating mechanism.  A circulatory water heater is provided with a caldron which may be closed by means of a cover.  The pulsating heating mechanism may be mounted to the caldron cover with the pulsat-ing heating mechanism and the cover being readily removable.  The pulsating heating mechanism extends downward into the caldron.  The pulsating heating mechanism is formed by a vertically standing sound muffling air cylinder with an intake muffler, a combustion chamber and a pulsation pipe connected to the combustion chamber.  The pulsating pipe exhausts into a cylindrically shaped substantially vertically mounted exhaust muffler cylinder mounted adjacent to the air cylinder within the caldron.  The caldron may be made of a synthetic material as the highest temperature which it must with-stand is that of the temperature of the water to be heated.  The water to be heated enters from the bottom of the caldron, is heated by the air and exhaust cylinders as it rises, and is heated to its highest temperature near the top of the caldron where it exits by means of a pretzel-shaped pulsation pipe.  The heating capacity may be doubled by using a second substantially identical pulsating heating mechanism which operates 180° out of phase without increasing the volume of the exhaust cylinder.

Title: Idle channel noise suppressor for speech  encoders
Inventor: BROWN ANTHONY K D
IPC: H04B14/04
Filed: 1979-06-12
Granted: 1982-07-06
Abstract: IDLE CHANNEL NOISE SUPPRESSOR FOR        SPEECH ENCODERS Abstract of the Disclosure The idle channel for a speech encoder is detected by the detection, at the encoder comparator output, of zero-level traversals caused by noise transient signals appearing at the analog input of the encoder.  In response to the detection of an idle channel, the encoder is caused to output a PCM code sample corresponding to a zero amplitude analog signal.  In order that a speech signal passing through zero amplitude during the sampling period not be confused with an idle channel condition, the detection circuit responds only to a plurality of zero-level traversals.

Abstract: Applicants:  James A. Fikes and Dana W. Meeks Title:       Log yarding Skyline Carriage ABSTRACT                 Sheaves mount a carriage on a skyline for yarding logs.   A load line having a hooked and hanging from the carriage extends through another sheave on the carriage to a winch on a yarder at one end of the skyline.  Brakes actuated by hydraulic cylinders are operable to look the carriage to the skyline and the load line to the carriage.  The skyline brake normally is released and the load line brake normally is set so that hauling in or paying out of the load line by the yarder winch effects movement of the carriage along the skyline.  A hooker on the ground actuates setting of the skyline brake and releasing of the load line brake by pressing a button on a radio transmitter which signals mechanism on the carriage to supply hydraulic liquid under pressure from an accumulator to the brake cylinders, and also to a hydraulic motor which drives the load line sheave to lower the lead line from the carriage.  The hooker receives the load line, hooks a load of logs and signals the yarder operator to haul in the load line to hoist the log load, whereupon the brakes are returned to their normal conditions so that further hauling in of the load line moves the carriage and its log load to the yarder.  The accumulator is regenerated to replenish its hydraulic liquid under pressure by a hydraulic pump driven by rotation of the load line sheave as the log load is hoisted and/or by rotation of a skyline sheave as the carriage is moved to the yarder.

Abstract: Abstract of the Disclosure A system for the precipitation of Al(OH)3 from green liquor is provided which comprises process and apparatus for feeding the green liquor into the bottom of a chamber containing a supersaturated solution of alumina trihydrate and seed particles.          The flow of green liquor into the bottom of the chamber is main-tained at a rate sufficient to suspend the seed particles in the chamber with minimum turbulence so that the liquor is in approxi-mately plug flow.  As Al(OH)3 precipitates on the seed particles, the particles grow larger and gradually move to the bottom of the chamber where they are removed.  The solution, depleted with respect to Al2O3, overflows the chamber to return to the process.

Abstract: ABSTRACT     A surface modified pigment formed from kaolin material and a process of producing same are described.    The pigment consists of pigment particles of kaolin material, and on the surface of the particles a primary and a secondary layer are precipitated. The primary layer consists of an anionic A12O3-SiO2 hydrate gel having a molar ratio of SiO2:A12O3 of from 3 to 30 and is present in a quantity corresponding to from 2 to 15% by weight of SiO2, based upon the original quantity of kaolin material. The secondary layer consists of a polymeric binder which is bonded to the primary layer by hydrogen or ion bonding and which is included in a quantity of at least 2% by weight, based upon the original quantity of kaolin material.    The pigment is prepared by dispersing the pigment particles in water and providing them while they are dispersed, with precipitated primary and secondary layers. The primary layer of anionic A12O3-SiO2 hydrate gel is precipitated by acidifying water glass with an aluminium salt and acid and the secondary layer is formed by adding a polymeric binder, the primary and secondary layers being bonded to one another by hydrogen or ion bonding. The pigment is retained in aqueous dispersion until after application.    The surface-modified pigment is intended for use in paper and coats of paint.
