Abstract: ABSTRACT OF THE DISCLOSURE     A digital signal is divided into a series of base words with each m bits of data.  Each base word is converted to a converted word having n bits of data, wherein each of n and m is an integer and n is greater than m and the converted word has a predetermined maximum number of consecutive digital zeroes.  The value of every odd-numbered bits of said converted word is detected.  The converted word is controlled in response to the result of the detection and modulated as an NRZI (non-return to zero, inverted)-coded digital signal with a DC component of zero.

Abstract: ABSTRACT OF THE DISCLOSURE     To attach a nut to a plate-shaped workpiece, es-pecially to a metal sheet, in such a way that it has self-locking properties without additional aids or parts, the force fastening the nut and acting on a free thrust sur-face of the nut is divided into at least two effective components generating a shearing stress in the nut mater-ial, transverse deformation of a part of the nut facing away from the workpiece being produced, and the thread diameter in the thread region deformed for self-locking purposes being reduced, whilst at the same time the thread pitches are inclined towards the centre axis.  A nut which can be used either as a locking nut or as a non-locking nut is characterised by a force-deflecting design of the thrust surface.

Abstract: APPARATUS FOR VERTICAL GEL ELECTROPHORESIS                  ABSTRACT OF THE DISCLOSURE An electrophoresis cell assembly is disclosed which accommodates one or more vertically oriented gels of either slab or tube geometry held in a lateral enclo-sure attachable to a U-shaped frame to form a liquid-tight upper buffer chamber surrounding the upper end of the gel.  Mated features on the gel enclosure and the frame permit one to slide the enclosure up against the frame into pivotal contact therewith, and to then lock the enclosure into position against the frame, sealing the buffer chamber thus formed around the upper end of the gel, all done in one simple movement.  The design overcomes problems in both sealing and assembly, and provides a reliably sealed construction which may be combined with other pieces of equipment normally used in electrophoretic separations to provide a complete cell.  The entire construction can be assembled and disassembled with unusual ease.

Abstract: ABSTRACT                A veneer anchor for use in a dry wall construction system which anchor comprises a plate member having a vertically projecting bar portion secured thereto and disposed in substantially parallel relationship with said plate member. The plate member includes end members disposed in substantially perpendicular relationship with respect to said plate member with the end members being bifurcated and having a pronged outer end configuration.  The anchor is employed to secure a wall board or insulation layer to a vertical channel or standard framing member and to thereafter maintain the structural integrity of securement of the anchor with respect to the channel or framing member, notwithstanding the ultimate shifting, deterioration or disposition of the wall board or insulation layer.  Thereafter, a wall-tie is inserted between the plate member and the projecting bar portion and the wall-tie is built into the outer wythe of the wall system.  The wall-tie is capable of vertical adjustability along the length of the projecting bar portion which in conjunction with the plate member concomitantly restricts horizontal movement of the wall-tie.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention discloses a read/write for an IC card as an external memory which is constructed with a carriage longitudinally movable in a casing which is normally held in a waiting position,  The carriage is held by a spring and moved to an operating position by manually inserting the IC card engaging therewith against the force of the spring.  A block having contact pins is snugly embraced by the carriage and is adapted to vertically move relative to the carriage when the carriage is moving to the operating position by sliding up a sloped floor to establish an electrical connection with contact points on the IC card.  The IC card is held by angularly movable hooks actuated by a lever to be moved by the carriage.  The hooks are retracted by disengaging the lever from a latch.          Concurrently, the carriage is returned to the initial waiting position to eject the IC card out of the casing.

Abstract: Abstract The invention provides a method and apparatus for radix-.beta. non-restoring division.  The division process occurs in four phases.  In a first phase, the input operands are transformed to produce a divisor lying in a designated numerical range.  Next, a transitional phase involves generating an initial radix-.beta. quotient digit from the transformed numerator.  An iterative phase of the process generates succesive partial remainders according to a recursive method.  From the sign and a single radix-.beta. digit of each of these partial remainders, the process generates a radix-.beta. quotient digit.  Further, a fourth phase, which may run concurrently with the transitional and iterative phases, involves accumulating succesively generated quotient digits to produce a final quotient value.

Abstract: (57) Abstract The present  invention relates  to a process  for recovering chemicals and energy from cellulose waste liquors preferably black kraft liquor obtained in a paper pulp sulphate process, comprising the following three distinct and separate steps:            In the first step the concentrated black liquor is gasified in  a  pressurized  gasification  reactor  by  so  called  flash pyrolysis at 700 to 1300°C, preferably 800 to 1000°C, normally 800 to 900°C, whereby an energy rich gas is produced and in which the inorganic chemicals of the black liquor are contained in the form of molten suspended droplets mainly comprising sodium carbonate and sodium sulfide.            In the second step the gas from the gasification reactor is rapidly cooled through direct contact with water,  and with green liquor, which is formed when the molten droplets and the hydrogen  sulphide  are dissolved  in the quench  liquid. The  cooled gas  subsequently passes  through a  scrubber.  In the  lower  section of the  scrubber the gas  is washed with circulating green  liquor  and  in the upper  section of the scrubber  the  gas  is  washed  with  a  sodium  hydroxide  (or carbonate)  solution and water  for complete  removal of any remaining sulfur bearing components in the gas.            In the third step the now sulfur and particulates-free gas is used as a fuel for generating steam and, if it should be economically justified, also for production of electric power.

Abstract: ABSTRACT OF THE DISCLOSURE         A tandem-axle walking beam suspension is disclosed which uses bushings of novel design in the bores at opposite ends of the walking beams.  The cores of the bushings have projecting ends each of which fits between the bifurcated end of one of the pair of axle bracket arms which straddle one end of each walking beam.  A removable fastener, such as a nut and bolt is used to connect each projecting bushing core end and its associated bifurcated axle bracket arm.  The resulting new system of connecting the equalizer or walking beams to the axle brackets provides easier serviceability of the beam end connections during repair or replacement and by using shims in the connections provides a convenient means of suspension alignment.
