Abstract: METHODS OF AND APPARATUS FOR COATING LIGHTGUIDE        FIBER AND PRODUCT PRODUCED THEREBY            Abstract A coating material is applied to drawn lightguide fiber in a manner which substantially prevents the inclusion of bubbles and which causes the fiber to be disposed substantially concentrically within the coating layer.  The lightguide fiber is advanced through a continuum of coating material, which extends from a free surface of a reservoir and through two dies that are arranged in tandem, at a velocity which causes air to be entrained in the coating material.  A pressure gradient is established between portions of the first die adjacent to its exit orifice.  A first one of the dies communicates with the reservoir and the second die and further communicates at the interface of the dies with a pressurized supply of the coating material.  The pressurized flow sufficiently enhances the pressure gradient in the first die and establishes sufficient volumetric flow of coating material upwardly through the first die to cause any bubbles in the coating material on the advancing fiber to be removed by recirculating streamlines and to be moved upwardly into the reservoir. The bubbles are substantially immediately removed from the reservoir by providing fluid exit channels through which bubble entrained coating material exits the reservoir in the vicinity adjacent the first die.  Not only is the coating in the fiber substantially free of entrained air as it leaves the second die, but coalescing bubbles do not misalign the fiber and the fiber is disposed concentrically within the coating because of a precentering effect of the first die and enhanced self-centering caused by pressure in the chamber.

Abstract: ABSTRACT OF THE DISCLOSURE          A carrier apparatus  (40)  for mounting logic com-ponents on the surface of a circuit board (41).  The carrier apparatus (40) includes a housing structure defining top and bottom surfaces and further defining a cavity (50) in the bottom surface for receipt of a logic component (51).  A recessed cover portion (56) is attached to the housing so as to enclose the cavity (50) thereby effectively sealing the logic component (51) in the housing.  The carrier apparatus (40) includes means for mounting the housing on a circuit board such that the cover (56) does not make contact with the surface of the circuit board (41).  The housing further includes means for electrically interconnecting the logic component (51) to the circuit board (41).         In  yet  another  embodiment,  a  carrier  apparatus (100) for mounting logic components on the surface of a cir-cuit  board  (41)  is  disclosed which  utilize  ground  and voltage planes together with alternating signal (118) and AC ground (121) traces so as to effectuate coplanar/strip-line and coplanar/microstrip transmission line environments along portions  of the  signal  traces  (118).  Consequently,  this results  in  signal  lines  having  a  controlled  impedance environment  and  minimized  crosstalk  between  neighboring signal leads lying in the same plane.

Abstract: ABSTRACT OF THE DISCLOSURE         There is disclosed a signal processing circuit for an image sensor.  This circuit comprises: an image sensor having an optical black level detecting portion (i.e., an optical black); a buffer circuit for receiving an output signal from the image sensor; a clamping circuit for receiving an output from the buffer circuit; and a low-pass filter provided between the buffer circuit and the clamping circuit.  This low-pass filter is made operative by a switching circuit in the interval responsive to the black level detecting portion in the output signal of the image sensor, while it is made inoperative in the interval responsive to the image pickup signal detecting portion.   According to this circuit, the black level drift can be followed, thereby preventing the appearance of line noise on the screen without being influenced by the sag component due to the AC coupling.

Abstract: ABSTRACT OF THE DISCLOSURE A music data compression system is disclosed which includes an analog to digital converter for converting the analog music signal to digital sample signal form, a digital compression filter for compression filtering the digital sample signals,  and an encoder for truncated Huffman encoding the compression filter output.  An entropy setting unit is included in the system for step control of the signal supplied to the digital compression filter in accordance with one or more threshold levels of the envelope of the  music signal, and for reducing the entropy of the signal with increases in the energy level of the music signal.   Different codes may be implemented in accordance  with  the  threshold(s),  and  an identifying code word is inserted in the Huffman encoded stream.  A decoder, digital reconstruction filter, and digital to analog converter are used to reconstruct  the  analog  music  signal.   The identifying code word in the encoded signal stream to the decoder is used to select the necessary algorithm for decoding, and an entropy setting unit is included for step control of the gain of the digital reconstruction filter output under control of the identifying code word when step gain control is included prior to compression filtering.

Abstract: ABSTRACT OF THE DISCLOSURE        A rotary vaned pump has solid vanes of fixed length sliding in a boss mounted for rotation about a longitudinal axis eccentrically displaced from the longitudinal axis of the pump chamber, so as to provide respective pump compartments in the pump chamber which vary cyclically in volume and are arranged to pressurise fluid entering the pump chamber through an inlet opening and discharging from the chamber through an outlet opening.  Each leading vane edge that passes over the inlet opening is formed as a shearing knife edge that shear-cuts any cuttable solid material in the entering fluid that is engaged by the edge as it enters the pump chamber through the inlet.  Such solid material is thereby cut into pieces which can be handled by the pump without jamming rotation of the rotor.  The leading edge of the inlet opening is also formed as a knife edge that cooperates with the vane edge to shear the solid material.  The vanes slide radially in the rotor boss and their tips engage the rotor chamber cylindrical interior surface surrounding the longitudinal axis, this surface being formed as a specially calculated face cam permitting the use of the solid constant length vanes.

Abstract: ABSTRACT         This invention relates to a process for achieving and maintaining the clarity of bicarbonate bearing waters.  The process has application to treating bicarbonate bearing waters where such waters are for injection into a subsurface formation, for waste disposal, or for any other industrial purpose where bicarbonate bearing waters may need to be treated.  The process is intended to prevent an imbalance in the bicarbonate/carbonate equilibria in bicarbonate containing waters as the water is treated in a treatment process.  The process involves the measurement and control of carbon dioxide content to prevent the deposition of both organic and inorganic solids.  By use of the process the specifications on turbidity and suspended solids content in treated water can be met with a significant decrease in, or possibly elimination of, the dosage of other treating chemicals.
