Abstract: GRAPHIC AND TEXTUAL IMAGE GENERATOR                FOR A RASTER SCAN DISPLAY          Abstract of the Disclosure An architectural design for a raster scan display apparatus, for generating both graphic and textual images.  The display refresh memory (46) is broken into an information memory (79) and an attribute memory (120).          The information memory has one location for each picture element in the display; the attribute memory is of (ower resolution and has one memory location for a plurality of picture elements.  The attribute memory provides foreground and background attributes which can be varied only in multiples of picture element locations.  In response to the information memory contents for each location, either the foreground or the background attribute is provided to the display, from the attribute memory.    The information and attribute memories operate in conjunction with a pattern generator (136, 160, 162) to establish the information to be displayed between pairs of points.  The pattern generator provides a finite length, repeating pattern of 1's and 0's representing the selection of foreground or background attribute for each location intermediate first and second points on the display.  The rate at which the pattern is shifted may be varied to alter character or object size on the display, thus permitting all sizes of a character to be represented in memory in a cell of small fixed size.    For generating two-dimensional images, two pattern generators are employed;  the second pattern generator provides the starting positions and patterns for hte first pattern generator.  This permits characters to be reoriented-i.e., tilted, italicized, etc., with simple commands which reset the parameters governing the operation of the pattern generators.

Abstract: ABSTRACT OF THE DISCLOSURE A multistage thermostat is operated by comparing the thermostat setpoint and the sensed temperature over a continuous series of discrete intervals of time.  When a sudden change occurs between the sensed temperature and the setpoint, the magnitude of this change is evaluated in a comparator and if necessary the system is reset to compensate for the change to operate in the most efficient manner.  The adjustment of a con-stant supplied to an integrating circuit that forms part of a signal processing circuit for the thermostat provides the adjust-ment when the predetermined level of change is made.

Abstract: HANG-UP FIXTURE                   Abstract of the Disclosure A fixture for installation in position suspended from an overhead horizontal beam such as an inverted "T" shaped beam at the ceiling of a store.  The fixture has a top portion with an upper surface adapted to bear against the base of the beam and can be moved to its installed position on the beam solely by twisting it about a vertical axis in one direction, and returned to its released position solely by twisting it about the same axis in the opposite direction.  The fixture includes a  pair of projections extending upwardly from the periphery of the top surface, each having a fin extending over and spaced from said top surface and tapered outward-ly away from the top surface of the fixture so that when the fixture has been twisted to its installed position the fixture is locked to the flange of the beam that is between the top surface of the fix-ture and the bottom surface of the fin of the fixture.  The fixture has a flange extending downwardly from and across the top portion whereby it may be twisted to or from-its installed position.  This flange also serves to receive a suspension cord for suspending an article from the fixture, and the flange has means for holding the cord wound on the flange when the fixture is not in use.  A tool for installing the fixture on or removing it from the beam comprises a pole having at one end a surface upon which the fixture can rest and whereby it may be twisted to or from its installed position.

Abstract: Abstract The present invention relates to a method of uniformly induction heating a metallic elongated element having longitudinal sections of differ-ent thicknesses.  The invention more particularly relates to a method of ensuring substantially uniform heating for a metallic elongated element over the whole length thereof irrespective of the existence of different thickness or diameter section(s).  Specifically, an inductor for practicing the method of the invention is constructed in the form of a multi-turn coil which is adapted to be separated into a certain number of coil segments corresponding to the geometrical configuration of the metallic elongated element.  Uniform distribution of temperature over the metallic elongated element is achieved by properly program controlling power supply to the respective coil segments and thereby controlling the heating time of the various longitudinal segments of the element.  The inductor itself is main-tained fixed.  Thus, irrespective of the irregular stepped configuration of the metallic elongated material, substantially uniform heating is ensured by preparing an adequate program corresponding to it.

Abstract: METHOD AND APPARATUS FOR COMPILING     DIGITAL IMAGE INFORMATION            Abstract of the Disclosure Video data bus 8, video memory modules VMl-VMN, and bus arbitration circuits BACl-BACN interact to provide digital image information for display.  Data processor 1 addresses the video memory modules via bus 2, in order to assign a priority value to picture element data stored in the video memory modules.  Upon command of the data processor, a frame 5 or 300 of picture element data is serially compiled on bus 8.  Contention between video memory modules for access to the video data bus is controlled by the bus arbitration circuits, the highest priority value of the picture element data gaining access. In one embodiment, the priority value represents the depth of a point of a solid object for display and/or the relative depth of picture element data comprising the object for display.  The data processor may change the priority value associated with picture element data for display as well as the coordinates of data location in the display.  Accordingly, textual characters having the highest priority and solid objects having a lesser priority may appear to move in front of one another on a background having the lowest priority value without interference in a sequence of frames of information for display.

Abstract: Abstract of the Disclosure Only a part of the synthesis gas supply is passed through a first internally cooled catalytic reactor (1) and the hotter gas coming out of it is reunited with the remaining gas supply for passing through an adiabatic reactor (2) that is followed by a heat exchanger (3) on its way to a second internally cooled reactor (4) in which the methanization reaction is completed.  Water is heated up to practically the saturated steam temperature in the cooling system of the last mentioned reactor and is converted to saturated steam in the cooling system of the first internally cooled reactor.  The saturated steam is super-heated in the above-mentioned heat exchanger.  To make the process run more smoothly a steam drum is provided through which the hot water piping between the cooling systems of the two internally cooled reactors runs and the saturated steam is brought into the steam drum and from it to the heat exchanger before it is superheated.  Additional heat exchangers are used for first preheating of the water and for two stages of preheating the synthesis gas.  Adjustments of the proportion of the synthesis gas that goes through the first internally cooled reactor makes possible a control that assures that the outlet temperature of the adiabatic reactor will not exceed a safety limit required for the stability of the catalyst.  No mechanical propulsion, nor compression, of the gas is necessary at any stage, nor any recycling, nor introduction of steam for control of the process.

Abstract: ABSTRACT OF THE DISCLOSURE         An elastic nail for fixing a bone fracture of the femur including an elongated cylindrical nail jacket having a distal end, a proximal end and an outer surface.  The nail jacket is curved along its length between the distal and proximal ends and has a circular cross section between its ends with a region adja-cent its distal end having a cross section which differs from the circular.  The elasticity and curvature of the nail are such that when the nail is driven into the marrow cavity of the femur its distal end is supported by the cortical part of the bone.  The region deviating from the circular cross section has a concave face and a convex face which are curved predominantly about axes extending parallel to the lengthwise direction of the nail jacket.          The concave face forms a recess in the nail jacket, which recess is disposed at the inside of the curvature which relates to the entire length of the nail jacket.  The convex face extends only slightly beyond the circular cross section transverse to the longitudinal direction of the nail jacket to form edge regions.          Each edge region has a continuously curved surface joining the convex face to the concave face.
