Abstract: A cooler for gases generated from coal by gasification under pressure has a pressurized vessel (1) that accommodates an insert (5) with a polygonal cross-section made out of pipes (6) that are welded together gas-tight in conjunction with webs (7). The pipes in the insert are bent vertically in to create a roof (11) and parallel one another sector by sector with webs of uniform width. The pipes that abut at an angle at the edges of the sectors are united in pairs by forged crosstail butts (13). The crosstail butts are aligned along a straight line and completely occupy the spaces between the sectors.

Abstract: A power steering system having an electric motor (18) and including an input shaft (10) fixed to a steering wheel (15), an output shaft (11) coupled to the motor (18) via a reduction gear (17), and a torsion bar (12) provided between the input and output shafts (10, 11), the output shaft (11) being rotatable by the resultant of a manual torque for rotating the wheel (15) and the torque of the motor (18). The system comprises a sensor (20) for detecting the relative angular displacement between the input shaft (10) and the output shaft (11), and a microcomputer (28) having stored therein the relationship between the relative angular displacement and the motor current target value for determining the direction of rotation of the motor (28) and a motor current target value from the output of the sensor (20) to produce outputs. The relationship stored in the microcomputer (20) is a nonlinear re­lationship wherein variations in the motor current target value with the relative angular displacement are small in the range of small relative angular displace­ments but are great in the range of great displacements.

Abstract: A register management system has more physical registers for general purpose use than are named in the architectural system. A renaming system identifies particular physical registers to perform as architected addressable or general purpose registers. An array control list (ACL) is provided to monitor the assignment and status of the physical registers. A decode register assignment list (DRAL) is provided to monitor the status of all of the architected registers and the correspondence to physical registers. A back-up register assignment list (BRAL) is used to preserve old status information while out of sequence and conditional branch instructions are executed. The physical registers may retain multiple copies of individual addressable registers representing the contents at different stages of execution. The addressable register status may be restored if instruction execution is out of sequence or on a conditional branch causing a problem requiring restoration. The register management system may be used in a processor having multiple execution units of different types.

Abstract: Miniature scan modules which occupy a volume of less than about 1 cubic inch so as to facilitate installation in any apparatus which requires scanning of a light beam across a target and detection of light reflected from the target. The miniature size of the scan module enables it to be incorporated in various apparatus, such as keyboards or terminals and provide them with the ability to read various symbols, particularly bar codes. The module has at least two printed circuit boards on at least one of which a source of a light beam, such as a laser diode or light emitting diode is mounted and another board which may be fixed in the apparatus in which the module is installed. The boards are interconnected by structure including a flexure which defines a pivot axis for the light source and on the board which it is mounted. The flexure is made up of a plurality of elements which are insulated from each other and provide separate conductive paths for electrical power and signals between the boards. The board on which the light source is mounted is driven to oscillate about the pivot axis, thereby scanning the beam across the target. A photo detector may be mounted on the same board as the sensor and receives light reflected from the target, as through a collecting lens.

Abstract: The invention provides for improved identification and parentage analysis of horses by making use of a specific minisatellite region of horse DNA, or a single repeat sequence derived from this minisatellite fragment. This minisatellite fragment isolated from horse DNA is composed of a tandemly repeated sequence of about 20 nucleotides, reiterated 32 times. This repeated sequence has a conserved core sequence of 6-9 nucleotides, but exhibits variation outside this region. Using this fragment as a probe, many related sequences can be detected in the DNA of Equidae, enabling it to be used for pedigree analysis and the identification of individuals.

Abstract: A PLA is organized into a plurality of pages of programmable logic arrays, including means for selecting an appropriate set of one or more of the plurality of pages of programmable logic arrays, including means for selecting an appropriate set of one or more of the plurality of pages for operation at any given time. Means are provided for switching pages when necessary in response to input signals including, if desired, signals fed back from the output leads of the PLA, or internal leads within the PLA. By having only a selected one or more of the pages of the PLA operable at any given time, the number of product and sum terms functioning at any given time is significantly less than the total number of product and sum terms available in the device, thereby minimizing power consumption. Furthermore, by utilizing a paged architecture, speed is increased and power consumption reduced since the number of leads connected to, and thus the capacitance of, the product and/or sum term lines is reduced.
