Abstract: A B S T R A C T     The present invention relates to seed carriers, pre-ferably in the form of seed-containing sheets to be laid out on the ground.  Earlier the production of such seed carriers has involved high cost because the production could not be run continuously on a large scale.  According to the present invention it is possible to produce such seed carriers con-tinuously on a large scale owing to the utilization of forming wire machines for the production.  This is enabled by the fact that the seed carrier is formed in part of a peat material which is fibre graded, in that colloids  and small particles have been removed, and/or of a peat material having a degree of humification of 1 to 3 according to von Post's scale*, and in part of a fibre material interconnecting said peat fibres.          The seed carrier according to the invention may be used in growing all kinds of crop, preferably in growing plants in dry districts, for instance desert areas, where it will form a cover which promotes the retention of moisture in the underlying soil.     *  von Post's scale is described in a Ground Planning Report:          "Torv i Sverige, 1977:1", a planning report elaborated by "N?mnden f?r Energiproduktion:s planeringsgrupp f?r torv".

Abstract: EQUIVALENT STANDARD VOLUME CORRECTION        SYSTEMS FOR GAS METERS Abstract of the Disclosure A self-contained correction unit operable in conjunc-tion with a gas meter measuring an actual gas volume emits a digital output signal correlated to an equivalent standard gas volume therefor by correcting the actual gas volume for prevailing conditions of temperature and/or pressure.  A temperature and/or pressure transducer is utilized which when exposed to the gas flow emits an analog voltage signal proportional to absolute values of the sensed parameter.  By scaling the transducer output signal to a base condition voltage representing unity, a signal proportional to the desired correction is derived which is converted to a digital signal for supplying to a divider-counter.  Within the divider-counter, a series of repeti-tive pulses corresponding to the actual volume measured by the meter is divided by the digital correction signal to yield a digital output signal of the corrected volume at the base condition for which correction was being sought.

Abstract: Abstract or the Disclosure In an apparatus and method for record reorientation following error detection in a data storage subsystem each data track is subdivided into equal time-length recording cells which are sequentially numbered past an index point with the beginning of each field of each record coinciding with an initial cell for the field. Upon detection of a retriable error within a given field, the initial cell for the field is determined and stored, the subsystem is disconnected from an interfacing channel, and reorientation is attempted by advancing a transducer addressing the track past the index point to a location which is a selected distance upstream of the stored cell number.  If a selected channel command is then received within a given time interval, the subsystem is reconnected to the channel and reorientation is effected as the transducer enters the field the initial cell of which was stored.  If the selected channel command is received late, the subsystem waits one revolution of the track and then reorients without looking for further channel commands.

Abstract: IMPROVED COAXIAL FEEDER            ABSTRACT OF THE DISCLOSURE:      A coaxial feeder for connection to the inlet of a disc refiner include a channel defining means which contains a bladed screw the blade of which has a relatively short axial length and is housed to position coaxially of the discs, to which it feeds material for refining purposes, and in concentric spaced relation to the wall structure which bounds said channel. The material to be refined is introduced to the down side of the screw blade. At the outer periphery of the blade, at the lowermost limit of its travel, is a bar or plate-like control device which is substantially coextensive with the blade and arranged to specifically direct material to the apace between the. discs of the related refiner with minimal interference or disruption. The control device presents a surface to the material moved on the down side of the screw blade which effectively  inhibits bypass of material to the upside of the blade, having regard for the direction of its rotation in use. The arrangement assures a relatively free backflow of steam from the refiner discs along the upside portion of the blade, to vent to an expansion chamber rising vertically of the screw, which chamber houses means for controlling the inflow of material to the down side of the screw blade in generally bypassing relation to any significant portion of the backflowing vented steam.

Abstract: ABSTRACT OF THE DISCLOSURE     Solid carbonaceous materials and particularly coal are converted to gas hydrocarbon liquid by forming an aqueous slurry in which an amalagam of carbonaceous and non-carbonaceous particles are suspended in water.  The slurry is mixed together with an agglomerating liquid lyophobic to water and non-carbo-naceous particles and lyophilic to carbonaceous particles to form a mixture, and the mixture is agitated to preferentially agglomerate carbonaceous fine particles to form discrete agglo-merates having chemical and physical properties which are known and which are substantially uniform and constant.  The non-carbon-aceous fine particles remain substantially unagglomerated in the slurry and are separated from the discrete agglomerates.          The discrete agglomerates or reconstituted particles are then heated to greater than 1500°F and preferably greater than 2000°F in a controlled atmosphere to convert them into a gaseous product of unique purity and properties.   Alternatively, the reconstituted particles or discrete agglomerates are to a temperature of about 750°F to 1000°F under controlled  conditions to form a liquid product.
