Abstract: ABSTRACT OF THE DISCLOSURE           A pattern recognition circuit integral with a checkerboard diascope pattern used for spatial and shading error measurement and correction, performs detection in the time domain.  A locator time window is provided to positively locate and distinguish white-to-black transitions of coarse locators selectively placed within the diascope pattern from, for example, checker white-to-black transitions, or from white-to-grey transitions, even under adverse scanning condi-tions.  The circuit includes narrow time windows for identifying specific valid locator transitions, to thereby prevent triggering due to checker transitions, short noise pulses, etc.  During one field interval, each locator is scanned a number of lines, but only the middle line scan is used to describe the locator coordinates, i.e., is used to generate a locator strobe output for latching the coarse locator positions into a system memory for subsequent comparison with the diascope pattern to determine the coarse scan errors.  Checker tran-sitions are indicated via a checkers valid output which remains in a high logic state as long as checkers are being scanned.

Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without disconnecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element. The probe has at least two contact elements close enough to each other to simultaneously con-tact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resistance of the lead segment, which current flow is indicative of the condition of the element.

Abstract: ABSTRACT OF THE DISCLOSURE:         A method of preparing a combustible mixture in an internal combustion piston engine, in the working space thereof, defined by the surfaces of the cylinder, of the piston movable inside the cylinder, and of the cylinder head, the engine being controlled by timing means and oper-able through cyclical strokes which include exchanging the engine charge, compression, combustion and exhaust.  The method comprises the steps of connecting the working space to a source of air before the compression stroke, simulta-neously producing a mixture of exhaust gases and atomized fuel droplets, immediately supplying the mixture to a storage space closely adjacent and connected with the work-ing space of the engine and then during the compression stroke in the working space, providing for a laminar inflow of air by virtue of positive displacement of the fuel and exhaust gas mixture in the storage space, and compressing the same so that it maintains a non-combustible chemical composition during the compression stroke up until the time.   :: that the piston approaches the external dead center position which terminates the compression stroke.  Thereupon mixing the mixture with the air flow to produce a sudden pressure increase in the storage space causing immediate pumping into the working space of the mixture of air for subsequent combustion therein.  And an internal combustion engine to carry out said method.

Abstract: METHOD AND APPARATUS FOR RECOVERING PAPER-MAKING  FIBER FROM CONTAMINATED WASTE PAPER PRODUCTS           ABSTRACT OF THE DISCLOSURE      In the recovery of paper-making fiber from contaminated waste paper products including plastics film and other lightweight non-paper contaminants, the waste paper products are processed together with liquid in a pulper tub and contaminants and liquid are discharged through a junk outlet in the tub and into a junk remover.  In order to induce flow of light-weight contaminants into the junk remover, the latter has a weir adjacent its top and the level of the weir is controlled so as to maintain a liquid flow over the weir.  The liquid and lightweight contaminants entering the junk remover as a result flow upwardly to the weir and are discharged over the weir for subsequent processing and recirculation of paper stock to the pulper tub.  The materials flowing over the weir may be delivered to a rotary screening machine which defibers the waste paper and separates the fibers from the lightweight contaminants.  A novel rotary screening machine is provided for this purpose comprising a perforated drum rotatable about a generally horizontal axis and having openings at opposite ends for the delivery of liquid and paper furnish to the drum and the discharge of contaminants, respectively, a plurality of vanes for lifting material from the bottom of the drum to an upper region, as the drum rotates, and a rotor mounted within the drum and having blades which are disposed in spaced relation to the drum vanes in a position to intercept material falling from the upper region of the drum and fling it back against the drum.  The resulting fibers or flakes of useful paper are washed through the drum perforations whilst the rejected contaminants are conveyed to and removed via the discharge end of the drum.
