Abstract: ABSTRACT OF THE DISCLOSURE      This invention provides a spinning process which comprises generating a plurality of molten streams from a spinneret, the streams being formed from axially extending continuous segments of dissimilar polymers arranged alternately in side-by-side temporarily adhering relationship; quenching the streams to form filaments; and withdrawing the filaments from the streams, the streams being selected such that first and second of the filaments have substantially the same denier and are splittable into different numbers of sub-filaments.  In the prior art processes for making yarns of mixed denier per filament, a polymer is spun through a spinneret having capillaries of various lengths and/or cross-sectional areas.  The process of this invention overcomes problems associated with prior art methods where the quenching rates and stresses on the large and small streams are different causing morphological differences in the resulting filaments thereby causing variable dyeability and other problems.

Abstract: Abstract An information signal (INF) which is transmitted in coded form (CINF) from a signal source (RC) to a signal receiver (4, 5) is decoded at the receiver and at the same time marked (MINF) by the introduction of an identification infor-mation (ID) which is characteristic of the receiver or its possessor. The signal from a video disc (RC) carrying a coded programme is decoded and marked before it is supplied to a television set (6). Via said identification informa-tion a so called pirate copy is directly traceable to its originator. Thereby a protection against such copying is obtained. A device for the playback of a video disc of this type comprises a decoding and modification unit to which the necessary decoding information and identification information may be supplied from a personal data carrier (ID).

Abstract: ECHO CANCELER FAR END ENERGY DISCRIMINATOR            Abstract Energy in a received signal is distinguished as being whole band energy or partial band energy by comparing an average value of the received signal to a modified magnitude value of the received signal.  When the modified magnitude value exceeds the average value, the received signal includes whole band energy, otherwise the received signal includes only partial band energy.  This technique is employed in an echo canceler to enable updating an echo path estimate during intervals that the received signal includes whole band energy and to inhibit updating of the echo estimate being generated when the received signal includes only partial band energy.

Abstract: ABSTRACT   The present invention relates to a method for preparing a basic alum-inium sulphate of the general formula [A?(OHx)  (SO4)y  (H2O)z]  n where n is an integer x is 0.75 - 1.5; y is 0.7  - 1.07; x+2y is 3; and z is 1.5-4; whereat z is < 4 when the product is in solid form, and z is >4 when the product is in the form of an aqueous solution.  The compound produces positively charged complexes having charge-neutralizing properties in systems containing suspended or colloidal, negatively charged particles.  When carrying out the method an aluminium sul-phate is reacted with a compound from the group CaO, Ca(OH)2, BaO, Ba(OH)2, SrO and Sr(OH)2 to form the above compound.  The sulphate formed is then sep-arated.  Since the product is poor in sulphate, it can be used to advantage in paper-making industries employing closed pulp-water systems, to reduce the undesirable accumulation of sulphate ions.

Abstract: Abstract A  visually  and  electronically  readable  motor  driven register  has  a plurality  of  dependently. rotatable,  coaxial, incrementally  positionable,  number wheels which each carry a movable electrode fixed in a predetermined position relative to the numbers on each wheel.  Adjacent each movable electrode is inserted a fixed plate which carries a plurality of stationary electrodes,  each corresponding  to a number on the wheel and disposed circumferentially around a stationary main electrode which is capacitively coupled to the movable electrode.  When a number on a wheel is visually readable,  the movable electrode will be positioned so as to be capacitively coupled only to the stationary electrode corresponding to the readable number.  A microprocessor  provides pulses sequentially to the stationary electrodes of each wheel, and checks for a coincident processed output from the main electrode of the first wheel.  If there is a  processed  output  indicating capacitive  coupling  between stationary and movable electrodes,  the microprocessor  retains the electrode number indicative of the readable number of the first wheel and checks for a coincident processed output from the main electrode of the second wheel.  When all  the wheels have been read,  the first wheel is again checked;  if all the wheels have not been able to be read, the microprocessor will activate the motor to move the wheels until they can all be read.

Abstract: Abstract of the Disclosure An ink jet printer control circuit is disclosed in which provision is made for production of drop clock signal pulses for application to the electromechanical drop stimulation transducer of the printer.  Print enable pulses are provided by a state controller means to the charge electrode driver of the printer so as to permit selective charging of drops produced by the jet drop stream. An edge detector means is responsive to the leading edge of each pulse in the drop clock signal pulse train to provide an edge detection pulse. Additionally, an encoder arrangement provides a train of synchronization pulses, each such pulse signifying an increment of movement of the print receiving medium.  The state controller responds to the edge detection pulses and to the synchronization pulses and provides a print enable pulse upon receipt of an edge detection pulse next following receipt of a synchronization pulse.  The state controller means includes three flip-flops which are sequentially actuated so that a print enable pulse is provided only after receipt of at least two edge detection pulses prior to each synchronization pulse.

Abstract: IMPROVED SPEED CONTROLLER FOR MILL DRIVES AND THE LIKE      ABSTRACT OF THE DISCLOSURE              A speed controller for a mill drive has two control portions.  The first control portion has a first speed of response for controlling mill speed during normal operation.  The second control portion has a second speed of response, faster than the first speed of response, for controlling mill speed following abrupt changes in load torque,  The first control portion has a reference speed input and this is compared with actual motor speed and the result gives a current reference signal.  The current reference signal is compared with a signal representing actual current to derive an error signal used to control the supply of power to the motor.  The second control portion multiplies the current reference signal with a signal representing flux to provide a signal representing a model of developed torque.  This is compared with a signal representing a model of load torque and the difference integrated to provide a signal representing a model of motor speed.  This is compared with actual motor speed and the difference integrated to provide the previously referred to model of load torque.  The model of load torque signal is differentiated to provide a compensating speed signal.  The compensating speed signal is used to adjust the comparison, in the first portion, of reference speed and actual speed.

Abstract: BOWL-TYPE VIBRATORY FINISHING MACHINE    Abstract A bowl-type vibratory finishing machine is disclosed which  employs  an  extremely  simple  yet  highly  effective arrangement of components enabling a relatively low-energy-input  drive  system to efficiently  impart  an  extraordinarily aggressive  finishing  action  to  a  mixture  of  workpieces  and finishing  media  contained  within  an  annular,  trough-like finishing chamber defined by a movably  supported bowl.   The finishing chamber extends  substantially horizontally  about a substantially vertical center axis.  An eccentric drive shaft extends along the center axis and is journaled by bearings which are connected to the bowl so that t when the drive shaft is rotated, vibrations generated by the unbalanced nature of the drive shaft are transmitted to the bowl and cause the bowl to vibrate generally about a nodal point located along the central axis.  A feature of the invention lies in the proper selection of a nodal point location which maximizes the efficiency of the vibratory impulses that are imparted to the contents of the bowl, and which permits a truly aggressive finishing action to be effected utilizing a relatively low-energy-input drive.  A further feature of the invention lies in the provision of a relatively  flexible  drive  shaft  restraint  which  assists  in assuring that the bowl tends to gyrate substantially about a selected  nodal  point  location  so  that  the  desired  type  of aggressive  finishing  action  is  achieved  with  efficiency  of operation.   Still another  feature lies in the simplification which the present  invention brings  to the  art of  designing bowl-type vibratory finishing machines.
