Abstract: METHOD AND APPARATUS FOR RAPIDLY FREEZING MOLTEN METALS AND METALLOIDS IN PARTICULATE FORM                         ABSTRACT     Described are a method and apparatus for freezing molten metals and metalloids in particulate or flake form at very rapid cooling rates.  A volatile coolant liquid is fed to the center of a rapidly rotating disc-like member to create an outwardly flowing film of coolant across the surface of the member.  The material to be processed is fed to the coolant film at a location spaced from the center and is thrown outwardly by centrifugal forces while being cooled by vaporization of the liquid.  The rotating member may include upwardly projecting vanes for collision with the outwardly flowing material to produce a higher surface area product.

Abstract: SOLID STATE DEVICES PRODUCED BY PLASMA DEVELOPING OF RESISTS            Abstract of the Disclosure This invention relates to the production of solid state devices by a process which includes at least one pattern delineation step involving dry etching of a negative acting resist film on a substrate.  The film comprises a polymer typically containing a halogen, and at least one type of silicon-containing or nonsilicon-containing organometallic monomer.  The radiation, typically X-ray radiation, locks the monomer or monomers into the polymer, with a subsequent fixing step removing the unlocked monomer or monomers in the unirradiated portion of the resist.  The film is then exposed to a plasma comprising oxygen, which removes the unirradiated portion at a faster rate than the radiated portion, producing a negative resist pattern.  The plasma development is typically accomplished by reactive ion etching.  Sensitizers may be used to extend the wavelength response of the films, typically into the ultraviolet or visible regions.

Abstract: X. KNEIB, G. VENSKO                Abstract of Disclosure A dynamically programmable processing element (DPPE) is disclosed which element has the utility in a digital processing system which requires complicated arith-metic procedures to be implemented.  The DPPE device is a special purpose computer which essentially has a program bus for transmitting and receiving program data from an external source.  A data bus is also provided which bus can transmit or receive digital data.  Coupled between the buses are input and output registers or buffers which are capable of storing transmitted or received data propagating on either of said buses.  A program memory has an input coupled to said program bus and means coupling the output of the program memory to the program bus.  A data memory has an addressable input means coupled to the program bus and an output coupled to the data bus.  Based on the orien-tation of the buses and the memories, the program memory can receive program information of data from an external source and data from the data memory can be transferred to the external source.  In this respect the DPPE can be re-programmed in real time by the external source.  The DPPE can also execute program instructions by fetching them from the external source as well as executing its own program instructions as stored in its program memory.  The structure and format of the DPPE enables it to interface with an ex-ternal source such as a microprocessor to assist and perform program instructions, as well as to perform arithmetic opera-tions on data from the microprocessor and to communicate with the microprocessor after completion of the various routines.

Abstract: ABSTRACT OF THE DISCLOSURE        A printer head of improved design for a dot line printer, for high speed data printout.          The printer head features independent magnetic circuits for driving each of the printer needles which form printed dots, with the magnetic circuits acting on armatures carrying the printer stylus, the armatures being mounted on the free ends of leaf springs.  The leaf springs can be designed for optimum performance, irrespective of magnetic circuit considerations, and the head assembly is based on a lightweight non-magnetic frame.  Substantially higher printing speeds than have hitherto been possible are attainable, due to reduced heat buildup in the drive coils, reduced interference between adjacent magnetic circuits, and optimized spring performance.

Abstract: ABSTRACT   In a sub-sea gas and oil well it is conventional to pump methanol or other chemicals through a flexible hose running down the well annulus to a chemical injection valve.  The invention involves providing an annulus control back pressure valve between the chemical injection hose and the chemical injection valve.  The back pressure valve utilizes the annulus pressure to oppose the chemical pressure in the hose, whereby when the chemical pressure in the flexible hose exceeds a predetermined value related to the annulus pressure the back pressure valve is forced open, but when the chemical pressure is below the predetermined value the back pressure valve closes thereby maintaining in the flexible hose a sufficiently high internal pressure to prevent collapse of the hose.  Continual collapsing and expanding of the hose is thus eliminated preventing any possible rupture of the hose.
