Abstract: Abstract of the Disclosure:           For use in deciding whether a single or a t-tuple error (t being greater than unity) is present in each bit sequence given as a primitive BCH code in accordance with a generator polynomial comprising a primitive and a non-primitive polynomial, an error checking circuit comprises first and second dividers (16, 17) for dividing each bit sequence by the primitive and the non-primitive polynomials to provide first and second signals, respectively.          If the bit sequence includes only a single error, the first signal represents one of non-zero residues which result by the division when such single errors are present at the respective bit locations of the sequence.  A memory (18) is preliminarily loaded with reference numbers corresponding to the respective non-zero residues and produces one of the reference numbers in response to the first signal only in the presence of a single error.  A comparator (19) compares the produced reference number with a residue represented by the second signal to carry out the decision.  Preferably, the memory is loaded also with the single error bit locations to locate the single error in a bit sequence being checked.  The circuit may be a microcomputer operable in the above described manner.          [Fig. 2]

Abstract: ABSTRACT OF THE DISCLOSURE       A multiple output d.c. to d.c. regulating circuit in-cluding an input protection circuit for providing protec-tion against input overcurrent, input transient voltages, sustained input overvoltage and input polarity reversal. The protection circuit powers a d.c. to a.c. inverter which generates high frequency spare-wave signals.  The square-wave signals are fed to a magnetic saturable reactor regu-lator which has its controlled windings connected by a rectifying filtering network to a pair of main output termi-nals and connected by transformer rectifier filter circuits to a plurality of auxiliary output terminals.  The d.c. output voltage across the main output terminals is sampled and is compared to a reference voltage of an integrated cir-cuit operational amplifier.  The output of the integrated circuit operational amplifier is connected to the control winding of the saturable reactor for controlling the con-trolled windings so that the square-wave signals are pulse width modulated to regulate the d.c. voltages developed across the pair of main output terminals and the plurality of auxiliary output terminals.  A soft starting circuit prevents high in-rushing currents from damaging the d.c. to a.c. in-verter.  An overload protection circuit senses overloads on the input and main output terminals and causes removal of power from the regulating circuit.

Abstract: Abstract of the Disclosure Improved Heterogeneous Immunoassay Method and Assembly A method and assembly provided for the detection and determination of at least one ligand in a sample suspected of containing the ligand. The method includes providing in a hand-held assembly having a first chamber end a second chamber separated by a separation means which permits the passage therethrough of materials of a relatively small size while pre-venting the passage therethrough of materials of a relatively larger size; a suspension in the first chamber of an admixture of a binding partner for the ligand and a labeled component. The labeled component is selected from the group consisting of binding partner, compound which can bind to the binding partner, compound which can bind to the reaction product of the ligand and binding partner, and compound which can bind to the ligand. The sample suspected of containing the ligand is introduced to the first chamber. The mixture is incubated for a time sufficient to form a reaction mixture containing free labeled component and a complex of the labeled component, binding partner and ligand. The free labeled component is separated from the complex by creating a pressure differential across the separation medium whereby the relatively larger size complex remains in the first chamber while the relatively smaller size free labeled component passes to the second chamber. The presence of either the labeled component present in the complex in the first chamber or the free labeled component in the second chamber is determined. The determination of such labeled component in either chamber provides a measure of the presence end quantity of the ligand in the sample.

Abstract: Abstract The present invention relates to a lifting wedge which is intended in particular for lifting a paper roll in the vertical position, and which is made up of a substantially cylindrical lifting wedge part (1) having the cross sectional shape of the core hollow of the paper roll, a lifting belt (2) fitted to the lifting wedge, and friction surfacing (3).         The lifting wedge accompanies during transport the roll to be lifted.     Previously known lifting devices of this type consist of lifting belts which are passed around paper rolls in the vertical position. The assembling of the belts and fitting them around the rolls is relatively difficult.     The lifting wedge part (1) according to the invention is divided in its longitudinal direction preferably into three wedge-shaped sections. The lifting belt (2) encircles that wedge section which has a larger cross sectional surface in its lower part, and forms a lifting loop above the wedge section. When the lifting belt is tightened, the wedge section encircled by it presses against the outer wedge sections, whereupon the friction surfacing (3) on the circumference of the lifting wedge presses against the inner wall of the core hollow and causes the lifting wedge to adhere reliably to the core hollow. The lifting wedge can be of wood and sawn into wedge sections, or it can be cast into wedge-shaped sections. The friction surfacing is preferably in the form of a rubber belt, or it can be friction-increasing material on the surface of the wedge sections. Band or rope can be used for the lifting belt.          Figure 1.

Abstract: ABSTRACT     A method and product for preventing an amendment of a notation on a notation sheet arrangement comprises the provision of a bag of two joined sheets with a notation contrast generating sheet introduced therewithin.  A notation is applied from outside of the bag on a notation area and the contrast generating sheet generates a notation contrast on and inside the bag in the notation area.  The contrast generating sheet is removed from the bag to at least such an extent that it leaves the notation area of the bag and re-introduction of the removed contrast generating sheet into the notation area of the bag is disabled by enabling by such removal of the contrast generating sheet a closure of the bag to automatically arise by enabling the two sheets of the bag to come together and adhesively join with one another along at least a part of the bag from which the generating sheet is removed.  The present invention has considerable advantages in terms of cost and flexibility of application over prior art techniques of irreversible notation recording.

Abstract: "METHOD FOR OBTAINING HORIZONTAL FRACTURES            IN AN OIL RESERVOIR"                      ABSTRACT OF THE DISCLOSURE            A closed pattern of wells is completed in an oil reservoir which is characterized by a tectonic stress regime conducive to vertical fracturing.  Fluid is injected into the outlying wells of the pattern at sufficiently high pressures to create vertical hydraulic fractures at these wells.  Thus pressure is applied to the reservoir from the corners of the pattern inwardly, to alter the stress regime to one conducive to horizontal fracturing.  The central well is then subjected to fluid injection while pressure is maintained on the outlying wells,to generate a horizontal fracture system emanating from the central well.
