Abstract: ABSTRACT OF THE DISCLOSURE A quasi-prepolymer-type urethane foam for a reaction injection molding (RIM) system comprises, for the polyol side, a blend of a long-chain polyol with a short-chain diol and/or triol and an organometallic catalyst and, for the prepolymer side, a unique high--27 to 31%--PNCO quasi-prepolymer made by reacting an essentially pure MDI with a selected low molecular weight (240 to 1500) polyol having a functionality of about 2.7 to 3.3.  The selected low molecular weight polyol is specifically a polyether polyol (i.e. a polyoxpropylene and/or ethylene polyol) initiated with TMP, hexanetriol, glycerine or other suitable polyol.  The quasi-prepolymer, while having the expected high reactivity, surprisingly gives good rapid cures in less than two minutes.  The resulting urethane foam is characterized by its excellent low temperature properties, especially -20°F cold flexibility and -20°F dart impact.  The quasi-prepolymer storage stability can be greatly improved by the inclusion of a small amount of a liquid MDI.

Title: Reduced connection for 22 character gas panel

Abstract: ABSTRACT OF THE DISCLOSURE    In driving gas panel or plasma display devices, characters are generated on the panel display as a sequence of dots by applying appropriate drive signals to selected orthogonal conductors, each conductor requiring an associated driver.  In a low character  count small plasma display such as a single row display utilizing a 5 x 7 dot character matrix, a significant load is presented to the horizontal drivers, while a substantial number of drivers are required to drive the vertical axis.  To improve the load distribution and increase the drive efficiency of such a system, the horizontal conductors are di-vided into four distinct groups, with associated drivers, while a single set of vertical conductors is used to drive the vertical con-ductors, which are positioned to intersect each of the groups of hori-zontal conductors.  The individual load requirements as well as the number of vertical drivers are reduced by a factor of four at a nominal increase in the number of horizontal drivers, thereby providing a sig-nificant cost reduction.  The specific wiring pattern used to achieve this result on a plasma display device is disclosed herein.

Title: Process for hydrotreating heavy hydrocarbon oil
Inventor: FUKUI YOSHIO
IPC: C10G47/12
Filed: 1978-06-06
Granted: 1982-06-22
Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a process for hydrotreating heavy hydrocarbon oil containing asphaltene and heavy metals in order to continuously convert it into a substantially asphalt-ene- and heavy metal-free oil in the recycling system.  The pro-cess comprises (a) hydrotreating reactor feed oil in the presence of a catalyst comprising a carrier containing magnesium silicate as a major component and having supported thereon one or more catalytic metal components selected from the metals of Groups Va, VIa, and VIII of the periodic table.  The hydrogen/oil ratio is 100 - 2000 (normal litre/litre), the temperature is 350 - 450°C, the pressure is 30 - 250 kg/cm2G, and the liquid hourly space velocity is 0.1 - 10 Hr-1.  The reactor feed oil is fresh raw heavy hydrocarbon oil and/or oil recycled from the last step (c), as later described, of the recycling system.  The hydro-treated product is withdrawn without entraining therein the catalyst.  The withdrawn hydrotreated product is (b) separated into a hydrogen-rich gas and a liquid product;  (c) the liquid product of step (b) as such or a mixture of said liquid product with fresh raw heavy hydrocarbon oil which was fed directly to this step as the case may be, is separated into a substantially asphaltene- and heavy metal-free light fraction and an asphalt-ene- and heavy metal-containing heavy fraction.  Finally, (d) the heavy fraction separated in step (c) is recycled to step (a), while making sure that the reactor feed oil to be hydrotreated in step (a) contains at least 5% by weight of asphaltene and 80 ppm or more of vanadium.

Abstract: Abstract of the Disclosure .             An accumulation of heat which takes place in gas turbines during deceleration of turbine components, such as during shut-down, may be dissipated by flowing a supply of cooling air through the turbine stages. The cooling air is selectively supplied after the supply of combustion air and fuel has been discontinued. The cooling air is preferably flowed through the combustion chambers prior to entry into the turbine stages so that the cooling air is initially pre-heated.          Additional air may preferably be supplied to the final ring of blades of each stage or of the final stage of a multi-staged turbine.

Abstract: 1               PHN.8911 C.         ABSTRACT:       A charge transfer device has one or more con-trol electrodes (8) connected to switching means (20) so that the electrode (8) can perform two functions. Normally the electrode (8) is used for charge transfer but it may be switched to act as a blocking electrode for blocking the charge (S) present underneath it for one or more clock phases.  This permits the device to be formed as a filter, an analog to digital converter or digital to analog converter in a simple and cheap man-ner.  The charge transfer channel may be split into sections using e.g. isolation diffusions (12 see Figure 4; or 51,52,52 see Figure 5).

Abstract: HEAVY DUTY POWER VALVE     Abstract of the Disclosure A brake valve is disclosed, which is provided with an enlarged chamber, at one end of which is slidably disposed an annular piston.  A reaction piston is carried on a valve rod; the reaction piston radially extends so as to cover the annular piston.  When the reacton piston moves toward the annular piston, flow of fluid through the valve is restricted and then halted.  Mating beveled conical surfaces are pro-vided on the annular piston and the reaction piston to pro-vide a mutual centering and seating action as the reaction piston is moved toward the annular piston.  Belleville washer elements are stacked in opposed array on the valve rod for resiliently urging the reaction piston into engagement with the annular piston, and for inhibiting mechanical shocks from being transmitted from the valve rod to the reaction piston,  and vice versa.  Conical fluid flow stop members regulate the flow of fluid from the valve chamber to down-stream brake elements.  These fluid flow stop members are slidable into and out of engagement with respective annular seats; directional braking action is afforded by these stop members, such that one or both of the brake elements are pressurized from the valve chamber.

This process is in-expensive and simple and gives a product of high quality.  The betulin, which usually accompanies the .beta.-sitosterol in the purification processes and which is a toxic agent, is substantially completely removed.
