Patent DE-3469645-D1 (DE)
Title: Process of producing custom programmed read only memory
Inventor: BATRA TARSAIM L
IPC: H01L21/82
Filed: 1984-06-04
Granted: 1988-04-07
Abstract: A late mask programming process is provided for factory programmed ROMs or logic circuitry. MOS transistors functioning as ROM cells or in logic circuitry are fabricated by a standard MOS Process. Then, a thin stop layer of silicon nitride is provided over the transistors followed by a layer of silicon dioxide. Programming is accomplished by applying a program mask and etching through the layers overlying the gate regions of selected transistors down to the silicon nitride stop layer. The silicon nitride stop layer prevents overetching and shorting of the gates. Then, ions are implanted underneath the gates of the selected MOS transistors to alter their threshold so, for example, as ROM cells they signify a different state than those cells whose transistor gates are not implanted with ions. The silicon nitride layer serves to stop the etch solution but permits the ions to pass through, penetrate the substrate and raise the thresholds of the selected transistors. The silicon dioxide layer stops the ions from being implanted into the nonselected transistors.

Abstract: The foundation structure for a number of machines arranged in a required relationship uses  modular base units so that different patterns can be built up. They are shaped as hollow, rectangular units with spacers between them so that motors (24) reduction gear units (25) etc. can be mounted inside. Side openings allows the driving spindles (26) to be connected, and top openings allows the spindles to be connected to the machines above. The spacers between drive sections can be formed by empty units (31), and all units can have top and bottom plates supported by side plates through openings. Around the edge at top and bottom is a groove for inserting locking elements secured by bolts.

Inventor: KLEIN DIETER H
IPC: C08G14/00
Filed: 1985-01-30
Granted: 1988-08-11
Abstract: A polyfunctional reaction product having functional phenolic OH groups is made available by reacting a phenol and an alkoxylated amine-aldehyde condensation product in the presence of a solvent and of an acid catalyst. This method makes it possible to prepare a polyfunctional phenolic reaction product which is soluble in organic solvents at a low ratio of phenolic OH groups to alkoxy groups without gelling. The reaction product is particularly useful as a curing agent for epoxy resins.

Title: Vertically and horizontally transferable ship
Inventor: PEYRE XAVIER
IPC: B66C13/02
Filed: 1986-02-10
Granted: 1989-01-19
Abstract: This invention relates to a boat designed as a self-hoisting unit for the vertical and horizontal transfer of persons and/or equipment from a ship to an offshore platform and vice versa. The boat carries a hollow mast forming a guide for a cable, the upper end of which will be attached to a carrier structure extending outwardly from a platform or ship. The mast is held by shrouds so as to withstand large flexural strains. For compensating sea-swell, the lower end of the cable passes over a damper unit comprising an hydraulic cylinder associated with pulleys of two opposed tackle-blocks. The cable is driven by a winch so that the boat can autonomously hoist itself to the platform deck level, or lower itself down to the sea or onto the deck of a ship. The mast height is sufficient for generating an uprighting torque ensuring horizontal stability of the boat during its ascent and descent. The boat is suitable for carrying a large number of persons, for instance as a lifeboat or for a shuttle service between offshore platforms.

Abstract: An improved process for removing free liquid from a hydrocarbon-rich gas stream is disclosed. Liquid is injected into the gas stream upstream of a chiller and downstream of an acid-gas removal system and any equipment that may affect the water content of the gas stream: compressors, columns, additional knockout drums, heat exchangers or the like. This enhances heat and mass transfer in a manner that both minimizes the formation of small droplets and encourages the coalescence of small droplets in the chiller. As a result, small droplets which would normally pass through a knockout drum and a standard mist eliminator are increased in size, prior to their arrival at a vapor-liquid separator to larger drops which are easily removed by the vapor-liquid separator, and the mist eliminator.
