Abstract: ABSTRACT            A disc for use as a rotor (10) or stator (18) in a multiple-disc brake.  The disc (10) has an annular peripheral band (15) provided with a series of circum-ferentially spaced through slots (12) which open through a periphery of the disc.  Each slot is defined by edges (13, 13a) which extend away from the periphery across the annular peripheral band (15) and are inclined in opposite directions (?) to a given radius (14) of the disc extending therebetween so that the slot tapers in a radial sense.     A multiple disc brake is also provided which has a housing (46, 47) containing oil or other coolant which encloses a disc stack in the form of interleaved sets of rotor (10) and stator (18) discs.  One set of discs (10) has a series of circumferentially spaced generally radially extending through slots (12) with inclined edges (13, 13a) extending from one periphery of the stage and the other set of discs (18) has a series of circumfer-entially spaced generally radially extending coolant access cut-outs (26) extending from the other periphery of the stack.  Portions of the slots (12) and cut-outs (26) are arranged to periodically overlap each other during relative rotation of the rotors and stators at locations outside the bands of frictional contact (15) of the rotors and stators to provide a radial flow path (31) for coolant across the stack.     The disc and brake are applicable to a wide range of uses including agricultural and industrial tractors.

Abstract: Abstract of the Disclosure A tire dismounting method and machine for use in dis-mounting a tire casing from a wheel rim.  The machine has a frame adapted to extend diametrically of the rim to span one-side thereof adjacent the rim flange, and to engage diametrically opposite portions of the rim flange to re-strain movement of said machine axially relative to the rim, while the rim and tire assembly are supported freely on the floor or the like.  A ram is pivotally supported on the frame adjacent one longitudinal end thereof for orientation of the ram with its axis generally parallel to the rim axis in operation of said ram.  The ram has a piston with a presser shoe pivotally carried on its free end for movement in a travel path radially outwardly of and adjacent the rim flanges and generally parallel to the axis of the rim through a working stroke extending axially beyond the remote rim flange.  The ram is supported for pivotal motion such that the ram axis can move through a range of about 15° from generally parallel to the rim axis to an acute angle intersecting the rim axis on the machine side of the rim.          The machine includes springs between the ram and frame for yieldably biasing the ram toward that end limit of its travel generally parallel to the rim axis.  A strap coupled between the springs and ram transmits the spring biasing forces and is removable so that the ram may be pivoted to a storage position against the machine frame.  A pair of outriggers may be mounted to the frame for swinging movement from a retracted to an extended position wherein the outriggers are adapted to rest upon the rim flange to reduce the likelihood of tipping of the machine relative to the rim.

Abstract: ABSTRACT            Memory module selection and reconfiguration apparatus in a data processing system wherein a modular working memory formed by a plurality of memory modules sends during the system initialization to a central processing unit information related to the capacities of the constituting modules.  The central unit processes such information and provides the memory with a set of information representative of the capacity of the first module, of the sum of the capacities of the first and second modules, of the sum of the capacities of the first, second and third modules and so on, up to the total capacity of the working memory.  This information set is stored in registers, each related to a respective module, of a module selection unit included inside the working memory.  When the memory is addressed a most significant address portion is compared at the same time by several comparators, one for each register, with the content of the several registers.  The comparison result signals in outputs from the comparators are applied to a decoder which, according to such signals, generates signals selecting one among the several memory modules.  The module selection unit is carried out by means of simple and fast circuits so that the module selection time is very short.

Abstract: PHB. 32,840.                  15 ABSTRACT:                  A circuit arrangement for improving the shape of a data pulse waveform prior to data slicing by correc-ting for s reduction of the high frequency content of the waveform using an adaptive crispening technique.  The arrangement comprises a high pass filter connected to an input art which the waveform is applied.  The filter separates the high frequency content which is multiplied by an amplitude correcting signal in a multiplier.  The signal data pulse waveform and the multiplier output are added in an adder to produce a resultant output waveform, which is fed to data slicer.  The resultant output wave-form is also applied to a peak-to-peak detector via a switch when the latter is closed periodically by a timing circuit.  The detector produces a control signal propor-tional to the amplitude of the resultant output waveform which it receives via the switch.  A subtractor produces the amplitude correcting signal as the difference between the control signal and a reference signal (RF).

Abstract: Method and Apparatus for determining cellulose-pulp properties A B S T R A C T        A multiplicity of cellulose-pulp properties (for example kappa number) are based on measurement of the weight of the cellulose pulp. Since during the manufacturing process pulp comprises a liquid suspension, it is normally necessary to treat the extracted samples, including a drying stage, prior to weighing the sample and subjecting the same to subsequent analysis. In order not to change the pulp from a chemical and/or physical aspect, the pulp should be dried carefully, which takes a long time. As a result of the invention it is possible to exclude the time-consuming drying and weighing operations, and the invention relates to a method for determi-ning cellulose-pulp properties, in which a sample quantity of pulp is taken and analyzed chemically or physically, characte-rized by the combination of first analyzing the sample and then determining the exact amount of pulp in the analyzed sample which is necessary for calculating the pulp property in question, by causing all of the analyzed sample, or a measured part thereof, in the form of a fibre suspension of low concen-tration to pass an optical measuring means while measuring the fibre content.       The invention also relates to apparatus for determining the lignin content of cellulose pulps.
