Abstract: SCAN CONTROL AND SENSOR SAMPLING SYSTEM   FOR SELF-SCANNED PHOTOSENSOR ARRAYS               ABSTRACT OF THE DISCLOSURE           A method and system is provided for driving a self-scanned photosensor array and sampling the sensor cells serially addressed by the array [which is compatible with] for integrated circuit arrays where high sensor cell scan rates are employed without compromising either image integrity or array frame rate.         End of line (EOL) and end of frame (EOF) timing signals generated by the array are sensed [by a monolithic integrated circuit which] and employed to limit the voltage amplitude swings of the signals to reduce noise modulation in the output video signal, and which forms a single synchro-nization signal accurately identifying the last cell of a frame to be scanned.  A row counter is synchronized to provide biphase array clock signals having minimal pulse skew between complementary outputs.  The flip-flops uniquely provide large voltage amplitude swings without attendant heat generation problems and reduce the effects of fixed pattern odd/even noise in the output video signal.         The sensor cells are serially selected to a wideband, high gain, integrated circuit transresistance video voltage amplifier which converts the recharge current of the sensor cells to a voltage waveform.  The amplifier further presents an apparent impedance to the array at the operating frequencies, thereby accommodating the recharging of a selected sensor cell in a time period small compared to the cell scan period.

Abstract: ABSTRACT OF THE DISCLOSURE   A device for controlling the opening and closing movement of a duct seal door of an automatic ice maker which requires a regulator for slowing down the closing of the door.  The movement of the door about its rotational axis is transmitted via connecting linkages to the closure regulator which com-prises a rotor positioned within a stator housing.  The rotor's movement is coupled to the connecting linkages via a one-way clutch which decouples the rotor when the door is being opened, and causes positive coupling therebetween when the door is being closed.  Disposed within the stator housing in a fixed-volume compartment is a viscous fluid, such as silicone gum.  The rotor and stator include opposed rippled surfaces between which the viscous fluid is coatively disposed.  The fluid acts as an inpendence to the motion of the rotor, which motion occurs only upon the closing of the door, to thereby provide a controlled slow closure thereof.

Abstract: ABSTRACT OF THE DISCLOSURE         A television receiver includes conventional circuitry for receiving processing and detecting an information bearing signal.  Vertical scansion means respond to recovered synchroniz-ing information and provide vertical scansion of a conventional cathode ray tube.  A horizontal oscillator coupled to an output amplifier and high voltage generator generates a scansion signal and provides horizontal scansion of the cathode ray tube.  An automatic phase control loop (APC) includes a differential amplifier phase detector which responds to the reference sync pulses and the horizontal output signal to produce an error voltage which is stored in a hold capacitor.  A speed control amplifier coupled to the receiver AGC system varies the amount of phase detector action directly with signal strength to vary system speed.

Abstract: Abstract of the Disclosure The separation of solid particulate matter from liquid material in which it is dispersed is improved by agglomerating the particles together by stirring to give homogeneous agitation.   A smooth, preferably cylindrical stirrer is employed.   In an important application fatty material such as fat or fatty acid mixtures in liquid phase, optionally dissolved in a solvent, is cooled to precipitate a fraction during homogeneous agitation to agglomerate the crystals as the precipitate.   An unusually good filtration rate is possible, even with very heavy crops of crystals.

Abstract: PHB. 32,548.           ABSTRACT       An apparatus for producing a signal representative of the sum of the currents flowing in conductors of a poly-phase electrical supply to a load contains a magnetic circuit in which is positioned a magneto-sensitive device.  An individual energizing conductor for the magnetic circuit is provided for each conductor of the polyphase supply and a rectifier arrangement is connected so as to feed each of these energizing conductors with a unidirectional current which is a measure of the current flowing in the corresponding conductor of the supply in a given direction relative to the load, this direction being the same of all conductors of the supply.  The unidirectional currents have a polarity such that the magnetic fields which are produced in the magnetic circuit will assist each other.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus for automatically packaging towelettes in en-velopes positioned in succession at an insertion station wherein the longi-tudinally folded leading end of a web of absorbent towelette material is severed to provide successive strips of predetermined length, and each strip is folded transversal first to a J-fold condition wherein the longer leg of the J is about twice the length of the shorter leg, and the longer leg of the J of each strip is folded substantially about its midpoint to form a folded towelette of three times the original longitudinally folded strip thickness as it is being thrust into an envelope positioned in timed relation at the insertion station.  The J-folded strip is transferred between the transverse folds by a conveyor comprising one or more pairs of driven rolls each pair defining a pass between them substantially equal to the thickness of a severed strip, and the rolls of each pair being relatively resiliently mounted to permit increased relative separation temporarily as for permitting passage of increased strip thickness.  Where the web is of non-woven fabric the longi-tudinal fold is ironed under heat and pressure to enhance the fold prior to severing.

Abstract: IMPROVED PROTECTIVE CLOSURE FOR EXTERNAL PIPE THREADS     ABSTRACT OF THE DISCLOSURE       A plastic closure securely mounted on the external threads at the end of a pipe, tubing, casing, or the like for protecting the external threads from damage.   The closure comprises a tapered sleeve which is normally uncompressed and compressed by tightening a metal strap enclosing the sleeve for securing it to the pipe end.   When the closure is mounted on the pipe end in its compressed condition, threads on the inner peripheral surface of the sleeve are urged into engagement with the external pipe threads for tightly securing the closure to the pipe end.  The sleeve has a conical seat for the strap in its normal uncompressed condition, and in the com-pressed condition of the sleeve the seat is cylindrical relative to the axis of the sleeve.  The sleeve has a flat surface on which the strap seal is placed and a slot for receiving a projection on the strap to prevent circumferential movement of the strap before and during tightening.

Abstract: RENEWABLE TIP HAMMER FOR A CRUSHER   Abstract An improved hammer design for a swing-hammer type crushing machine.  The hammer is in at least two pieces, a shank and a detachable tip section.  The shank is pivotably mounted at one end on a rod extending between a pair of radial discs spaced along the machine rotor.  The tip section is joined to the shank by a simple connecting pin which passes through co-aligned holes in a bifurcation on the tip and a lug extending outwardly from the shank.  Spaced apart tabs at the free end of the shank co-operate with a stop on the rotor to limit the pivotal movement of the hammer between predetermined limits such that the connecting pin is always confined between the pair of rotor discs during operation of the machine.  However, a worn or damaged tip section can be readily replaced in situ by removing the rotor stop, pivoting the hammer so the connection between the shank and tip are outside the rotor, and removing the connecting pin.                            -la-

Abstract: ABSTRACT OF THE DISCLOSURE          A multi-chip type CCD color camera is designed to displace respective chips relative to an object image.  The sampling action at respective CCD imager chips yields output signals having base-band components and side-band components partially overlapped with each other.  In order to separate two components, frequency converting technique is introduced in the signal processing circuit, wherein these components are interchanged in frequency.  It is very easy to cancel out original base-band components from respective CCD chips, because the phases of the base-band com-ponents are not influenced by chip displacement.  Accordingly, there is no need to adjust precise chip alignment in order to improve the resolution of the CCD color camera.
