Abstract: A B S T R A C T     In a system for transmitting information on an a.c. line from a transmitter unit to a receiver unit which is connected to the line at a great distance from the a.c. source supplying said line than the transmitter unit, information is transmitted on one of the phase conductors of the line in a form of a series of short-duration pulse-like amplitude reductions in the alternating voltage waveform on said phase conductor during one and the same half cycle of the waveform, whereat the pulses are mutually arranged in the pulse series to form a binary code word representing the desired information.  The short-duration pulse-like amplitude reductions in the alternating voltage waveform are generated by means of a current transformer, whose primary winding is connected in series with the phase conductor and whose secondary winding is short circuited by means of a switching transistor controlled by a control unit to be opened for a short duration for each desired pulse in the series of information pulses.  When the transistor is opened, a voltage regulator connected across the secondary winding of the transformer restricts the change in magnetic flux in the transformer core to a maximum value dependent upon the length of the pulse series. A current regulator is arranged to sense the current flowing through the phase conductor and the primary winding of the current transformer and, by connecting a load to the phase conductor on the side of the current transformer remote from the a.c. source, to hold the current through the primary winding of the current transformer over a given minimum value during the half cycle of the alternating voltage waveform when a series of information pulses is to be transmitted

Abstract: Abstract of the Disclosure Heat treatment of a material, e.g. a finely divided resin, wherein the material is introduced into a drum and agitated by rotating, spaced blades which whirl the material into a dispersion.  The action of the blades heats the resin particles so that heat for the heat treatment is provided.  The heat treatment can be, e.g. to cause small resin particles to coalesce with larger particles in the pro-cessing of polyethylene reacter flake, to improve flowability of the resin, or to admix resin and additive;  To obtain in-creased capacity while the size of the apparatus is main-tained within reasonable limits, two intersecting, generally cylindrical drums, each outfitted with an agitator, are used.          Apparently the dispersions of the respective agitators slam into each other in the vicinity of the intersection causing additional heating.

Abstract: ABSTRACT           A connector for connecting the abutted end portions of two pipes comprises a split ring having a pair of radially inwardly extending surfaces directed towards each other and each for engagement with a radially outwardly extending surface on a respective pipe end portion, the surfaces on the pipe end portions being directed away from the respective pipe ends. The connector includes operating means for causing radial expansion of the ring to disengage the ring from one of the pipes, the ring remaining engaged with the other pipe.  To this end the corresponding surfaces on the ring and the other pipe end portion may have a greater radial extent than the surfaces on the ring and the one pipe, so that the former surfaces remain engaged for all conditions of use of the connector. The connector may be engaged with the other pipe end portion either by operation of the operating means or automatically by suitably shaping the surfaces of the ring and the other pipe end portion which are initially brought into contact.          The connector is particularly suited for connecting the pipe sections of a pipe string for use in the drilling and/or completion of offshore oil or gas wells, particularly where the pipe string is to be subject to high axial load for example in pile driving.

Abstract: Abstract:          PRESSURE-TIME CONTROLLED UNIT INJECTOR     A fuel injector (10) is provided for each cylinder of an internal combustion engine, the injector including an electronically operated control valve  (60)  disposed between supply passage (4 2) and a timing chamber (80) to control the admission of fuel into and out of the timing chamber.  A primary pumping piston (62) and a secondary floating piston  (72)  are axially spaced within the central bore (70) of the injection body, and a normally closed injection nozzle (14) is situated at one end of the injector body.   A mechanical linkage  (27,  28,  30) associated with the camshaft of the engine drives the primary pumping piston (62) against the bias of a main spring (18).  The timing chamber (80) is defined between the  pistons  (62,  72)  and  a metering  chamber  (82)  is defined between the secondary piston (72) and the nozzle (14).    An electronic control unit (52)  responds to engine operating conditions,  and delivers a signal  to the control valve (60) to close the valve and seal the timing chamber  for  a  controlled period  of  time  to  form  a hydraulic  link  so  that  the pistons  (62,  72)  move  in concert during the injection and metering phases of the cycle of operation.   When the signal  from the ECU is terminated, the control valve opens, and breaks the link so that the primary piston  (62) moves independently of the secondary piston (72).     The  timing  function  can  be  adjusted  by  the  ECU relative to any preselected position of the crankshaft to optimize engine performance.   The metering function is controlled  by  the  pressure  drop across  a restricting orifice  (98)  in  the  passageway  feeding  fuel  to  the metering  chamber  (82).   The  flow rate  through  the metering orifice is proportional to the square root of the pressure drop across the orifice.
