Abstract: AUTOMATED INSPECTION SYSTEM ABSTRACT OF THE DISCLOSURE An automated pellet inspection system is disclosed wherein a succession of cylindrical pellets is transported along a sub-stantially continuous path.  In one portion of the path, rotating stacks of cylindrical pellets axially translate past an optical inspection station.  Signals are generated by an array of photo-sensitive diodes in response to light reflected from the surface of the pellets.  These signals are transmitted to data processing circuitry for analysis of the pellet surface features.  Means are provided for normalizing the respective diode output signals for variations due to factors unrelated to pellet surface features. Further, automatic gain control means are provided for modifying the signals derived for different pellets to accommodate differences in the reflectivity of these pellets unrelated to the surface features of interest.     The diode array is periodically scanned and the signals so derived are examined with respect to predetermined amplitude thresholds.  If no threshold crossing occurs during successive scans, the data derived is compressed and only data representative of a threshold change is retained and is compared to predetermined pellet surface criteria to determine conformance with the latter by the inspected pellet.  The inspection station further includes an addition diode array which receives light transmitted past the inspected pellet to determine such features as pellet diameter, roundness and the like.     Circuitry is provided for generating accurately known timing pulses which control the axial speed of the pellets advancing past the inspection station, as well as for synchronizing and correlating the collected data with the respective advancing pellets.  Based on the number of the aforesaid threshold changes and their location on the pellet, conformance to the predetermined criteria is determined.  A pellet sorter diverts unacceptable pellets from the path, while the acceptable pellets are transported to a collection station.

Abstract: A B S T R A C T               MONITORING THE FLOW-RATE CHANGES OF A PLURALITY OF FLUID STREAMS      Changes in the flow-rates of each one of a plurality of fluid streams which pass from respective conduits (13) to a common conduit (12) are monitored by taking a representative sample of fluid from a sampling point (16) of the common conduit, determining the change in composition of at least key components of the sample relative to a preceding sample obtained in the same manner, and computing from the change in composition the composition of the fluid stream whose flow-rate has changed, so that the fluid stream can be identified by reference to a library or database of fluid stream compositions.          When the fluid streams are gases (e.g. gases to be flared at an oil refinery or chemical process plant), each sample may be analyzed by a gas chromatograph (18) at predetermined intervals and the fluid stream whose flow-rate has changed may be identified automatically by comparison with a database or library (22) of fluid streams.  The thus identified fluid stream may be recorded and/displayed  (19).          The monitoring may be completely automatic. The method and apparatus of  the  invention avoid  the necessity to provide  flow-monitoring equipment in each conduit (13).

Abstract: ABSTRACT OF DISCLOSURE          To minimize carrier leak in the modulation of voice frequencies to the desired line frequency for a carrier system, a first balanced modulator is operated at a low frequency where low carrier-leak modulators may be constructed and a second balanced modulator, directly coupled to the first, is employed   The modulation frequency of said second modulator is very high compared to that of said low-frequency modulator.  The sideband obtained from the second modulation stage is remote from said high-frequency carrier and a band-pass filter selects the desired sideband and substantially eliminates the high-frequency carrier and the other sideband.  Thus, only a low amplitude of carrier leak is present which may cause interference with other channels.

Abstract: OUTPUT SPEED DROOP COMPENSATING          PUMP CONTROL                        Abstract The output speed droop compensating control is associated with a variable displacement pump con-nected to a motor in a fluid system.  The pump has a swash plate urged in one direction by a hydraulic fluid pressure moment acting through the pistons of the pump and a servo control cylinder having a control piston connected to the swash plate.  The control includes a control valve connected to the control cylinder and having a set position for maintaining a fluid pressure in the control cylinder to set the position of the swash plate for a particular pump displacement.  The control valve is movable from the set position to adjust the position of the swash plate by connection of the control cylinder to either control pressure or drain.  The con-trol valve includes a valve spool which responds, when the control valve is in set position to an increase in pressure in the control cylinder responsive to the swash plate being urged in one direction by said fluid pressure moment to shift the valve spool and connect the control cylinder to control pressure and thereby modify the position of the swash plate to cancel the effect of leakage at a higher system pressure.  A feedback linkage is connected between the swash plate and the valve spool and includes a spring providing a yieldable connection whereby the valve spool can shift in response to the increase of pressure in the control cylinder.

Abstract: ABSTRACT      A process for making amorphous semiconductor alloy films and devices at high deposition rates utilizes microwave energy to form a deposition plasma.  The alloys exhibit high quality electron-ic properties suitable for many applications in-cluding photovoltaic applications.  The process includes the steps of providing a source of microwave energy, coupling the microwave energy into a substantially enclosed reaction ves-sel containing the substrate onto which the amor-phous semiconductor film is to be deposited, and introducing into the vessel reaction gases includ-ing at least one semiconductor containing com-pound.  The microwave energy and the reaction gases form a glow discharge plasma within the ves-sel to deposit an amorphous semiconductor film from the reaction gases onto the substrate.  The reaction gases can include silane (SiH4), silicon tetrafluoride (SiF4), silane and silicon tetra-fluoride, silane and germane (GeH4), and silicon tetrafluoride and germane.  The reaction gases can also include germane or germanium tetrafluoride (GeF4).  To all of the foregoing, hydrogen (H2) can also be added.  Dopants, either p-type or n-type can also be added to the reaction gases to form p-type or n-type alloy films, respectively. Also, band gap increasing elements such as carbon or nitrogen can be added in the form of, for exam-ple, methane or ammonia gas to widen the band gap of the alloys.
