Abstract: ABSTRACT IMPROVED METHOD FOR CONTROLLING CONTRACTION IN SETTING CEMENTITIOUS SYSTEMS The contractions of aqueous hydraulic cement mixtures is controlled by the addition of a gas generating agent capable of generating gas in the mixture without the addition of activators or other agents, and which does not generate disagreeable or noxious ammonia fumes. The gas generation may be controlled over an extended period of time so that even slow setting cementitious mixtures may have their shrinkage or contraction inhibited during setting or hardening without the generation of ammonia fumes.

Abstract: ABSTRACT OF THE DISCLOSURE The present invention is employed in a system which has a bit map memory connected to a CRT display device and the CRT display device can display a fixed region of information and a scrollable region of information. In a preferred embodiment, the system uses a graphic display control circuit to change starting addresses and length ending values of the fixed and scrollable regions in the bit map memory.  By changing the starting address one scan line per frame, without any actual transfer of data in memory, from one location to another location, the present system effects a "smooth" scroll.  The system is able to scroll upward and downward.  The system uses logic circuitry to load an off screen segment of the bit map memory with additional scrollable information, so that (in an upward scroll load) as a top line of the scrollable information region is no longer displayed, new information will be dis-played at the bottom line of said scrollable region.  On the other hand during a downward scroll, a bottom line of information on the scrollable region of the screen will fade out and new information is added, from the off screen region, of the bit map memory to provide information for a new top line.  In addition the system has the ability to reorganize the information in the bit map memory in the event the size or location of the fixed region is to be altered.

Abstract: ABSTRACT OF THE DISCLOSURE      A multibit screwdriver has a plurality of bits provided in a circular pattern within a handle magazine.  A rotatable selector cup at the end of the handle permits selection of a desired bit from the magazine and placement in a chuck in the handle.  An elongate slot is provided in the cup to permit the manipulation of the bit.  The improvement in this screwdriver arrangement comprises an adaptation to the chuck and bit ends so that the selected bit end is readily placed within the chuck.  This feature is accomplished by providing a number of operative faces on the bit end equal to the number of bits provided in the handle.  Similarly, the chuck has a bore presenting a corresponding plurality of internal operative faces for engaging the bit end.

Abstract: CMOS INTEGRATED CIRCUIT TECHNOLOGY            Abstract To minimize the number of independent masking operations in the manufacture of a CMOS integrated circuit device using twin tub technology, the n-tub is made by separate phosphorus and arsenic implants through a common mask, and the p-tub is made by two separate boron implants through a common mask, complementary to that used for forming the n-tub.  One of the boron implants occurs before, the other after, the drive-in heating step.  After tub formation, further movement of the implanted ions is kept small by use of a high pressure process for growing the field oxide and by only limited further heating. Transistors are then formed in the tubs.

Abstract: ABSTRACT            The invention relates to a method for producing castings from cast-iron containing structure-modifying additives. There is prepared a molten cast-iron bath from which a sample is taken in a sampling and testing vessel. The sample and the vessel are brought to thermal equilibrium at a temperature above the crystallisation temperature of the molten bath and the sample is then permitted to soli-dify over a period of from 0.5 to 10 minutes. During the process of solidification the temperature is recorded simultaneously by two temperature responsive means, one of which is placed in the centre of the sample and the other in the immediate vicinity of the vessel wall. The disper-sion degree of the graphite phase is assessed in relation to known reference values for the same sampling and tes-ting method with respect to the finished castings with the aid of recorded values of supercooling in the molten sample at the vessel wall T*v, the recalescence at the vessel wall, rekv, the positive difference between the temperature and the vessel wall at the centre (.DELTA.T+) of the vessel, and the derivative of the temperature decrease at the vessel wall during the time of constant eutectic growth temperature          at the centre of the molten sample       , alternatively the maximum negative values (.DELTA.Tmax) of the temperature difference. When necessary, a graphite nucleating agent is added to the molten bath, or the degree of dispersion is lowered by implementing a holding time prior to casting. The morpho-logy of graphite precipitation in relation to known refe-rence values for the same sampling and testing method is assessed with the aid of supercooling at the centre (T*c) of the molten material, the recalescenee at the vessel centre (rekc) and the maximum growth temperature (Tcmax). The morphology is then corrected by changing the amount of structure-modifying agents present, so that the graphite precipitation takes a pre-determined, for example vermicular form upon solidification of the cast-iron melt subsequent to casting. The invention also rela-tes to various embodiments of the sampling and testing vessel.

Abstract: Abstract Steel structure for support of deck with production facilities for oil and gas at larger water depths and proce-dure for assembly of the structure while it is floating in the sea.    The structure consists of a vertical erected triangular trusswork tower 1 supported of a base 2 and reaching up to a level above the water surface where it supports a deck 3. The tower consists of three corner columns 6 interconnected by horizontal and diagonal trusswork stays. The tower is supported by three inclined supporting legs 4 which terminate in a base foundation. The supporting legs 4 are symmetrically arranged around the tower in such a way that each of them are facing a side plane of the triangular tower. The supporting legs are a trusswork construction of triangular cross-section.            By installation of the structure the tower 1 is brought to be floating vertically in the sea, while the supporting legs 4 are floating in approximately horizontal position with the installation frames 5 mounted. The upper part of the supporting legs is connected to a temporary joint 20 of the tower and the legs are rotated down into final position in that the installation frames by means of a wire system 14 are pulled into a connection point for the frame on the tower.
