Abstract: ABSTRACT OF THE DISCLOSURE   In PCM transmission, it is well known to transmit 24 voice-grade channels at a bit rate of 1.544 Megabits per second (Mb/3).  The number of channels which may be transmitted in about the same bandwidth is doubled by the use of correlative level coding, such is the midfield duobinary technique.  Because of the degradation experienced by the modified duobinary signal in passing over cable pairs, periodic regeneration of the signals is required for effective transmission.  The present invention is directed to a regenerative repeater which equalizes, amplifies, reshapes, ant retimes the received modified duobinary signal so as to provide a regenerated signal which is nearly identical with that originally transmitted.

Abstract: ABSTRACT OF THE DISCLOSURE           A spinning shot gun projectile comprises a cylindrical body having radially projecting vanes arranged with respect to the longitudinal axis of the body at an angle predetermined for air im-pingement during the flight of the projectile, thereby imparting a spinning motion to the same and insuring an accurate trajectory. The rearward portion of the projectile body has an axial bore dimension-ed to receive in bearing engagement the ram portion of wad means located forwardly of the powder. The thrust of the explosion thus is transmitted to the projectile centrally and forwardly of the same by the action of the ram, thereby further insuring true flight of the projectile.

Abstract: TITLE: OSMOTICALLY DRIVEN ACTIVE AGENT DISPENSER        AND PROCESS FOR MAKING SAME                 ABSTRACT OF THE DISCLOSURE An osmotically driven dispenser for releasing active agents, such as drugs, to liquid-containing environments, such as various body sites.  The dispenser comprises a housing made from a semipermeable material, a flexible partition that divides the housing interior into two compartments, an initially nonflowable, osmotically effective active agent composition filling one of the compartments, an osmotically effective com-position filling the other compartment, and an outlet passageway extending through the housing to the active agent-containing compartment.  In operation liquid is imbibed from the environ-ment through the housing into both compartments, thereby con-verting the active agent composition to a flowable form and causing the flexible partition to displace into the active agent-containing compartment and force active agent therefrom via the outlet passageway.  The release rate of active agent from the dispenser is a function of the combined rate of liquid influx into both compartments.

Abstract: ABSTRACT OF THE DISCLOSURE           A process is provided for the wet carbonizing of peat.          The raw peat is first formed into a pumpable aqueous suspension in a suspension-preparing apparatus.  The peat suspension is then preheated in series-connected heat exchangers and in a pre-heating tower.  The preheated peat suspension is then wet car-bonized in a reactor into which steam from a steam boiler is introduced at a temperature of 200°C,  The wet carbonized peat suspension is then cooled by heat exchanger in the preheating tower, is then mechanically dewatered in a dewatering apparatus and is then dried in a drying apparatus, with hot exhaust gases from the steam boiler being introduced as drying gas into such drying apparatus.  An important facet of this process, then of aspects of this invention is that the exhaust gases from the steam steam boiler are employed as drying gas in the drying apparatus and that the exhaust gas, carrying dust and water vapour, leaving the drying apparatus is purified and cooled in a wet separator.          Part of the water vapour in the exhaust gas is condensed in the wet separator and polluted water coming from the dewatering ap-paratus is cooled by heat exchange with the raw peat suspension in the heat exchanger thereupon is introduced as washing water into the wet separator,  The dust-laden  and heated drain water from the wet separator is returned to the suspension-preparing apparatus to be used as dilution water therein.  In this matter, efficient exhaust gas purification relating to equipment of the plant is combined with product and heat recovery in the plant.

Abstract: ABSTRACT OF THE DISCLOSURE A simple, inexpensive package for dispensing a ribbon of magnetic tape or other thin non-adhesive material is disclosed.  The package includes a roll of ribbon and a pair of annular paperboard sheets which each have a pressure-sensitive adhesive surface.  To form the package, the adhesive surfaces are pressed against the respective flat surfaces of the roll.  The adhesive is chosen so that the adherence of the sheets to the edges of the aligned ribbon coils is sufficient to maintain the ribbon in coiled condition but insufficient to prevent it from being progressively dispensed by drawing its free end away from the roll.

Abstract: Abstract The keyboard for pianos and similar musical instru-ments has key shanks (levers) formed of structural foam contain-ing glass fibers, there being only one shank construction for all the white keys and another for all the black.  The shanks are connected, at their outer ends, to self-positioning hollow key caps.  Each shank rests, at a laterally thickened central portion, on a synthetic resin balance rail from which an integral balance pin projects into a slot in such central portion.  The outer end of each shank rests on a synthetic resin guide rail having a guide pin formed integrally therewith and extending into the shank.  The laterally thickened central portions of the shanks are sufficiently close to each other to provide a strengthening effect creating much resistance to side forces such as occur, for example, during shipment.  The balance rail and guide rail, with their integral pins, are injection molded of solid synthetic resin and are mounted in strengthening rails which are metal ex-trusions.  These, and also extruded pivot rails and side rails, create such strength and rigidity that they are mounted directly on the bottom wall of (for example) a "suitcase" electric piano instead of requiring a separate frame or sheet which is in turn mounted on such wall.  The strengthening rails are keyed into slots in the bottom wall, for precise relative positioning of the rails.  There are two balance-pin holes in each thickened shank portion, and two correspondingly spaced slots in the wall, the result being that assembly or adjustment for either light or heavy touch may he achieved at almost no added manufacturing cost.
