Abstract: An electronically controllable pneumatically powered valve actuating mechanism for use in an internal combustion engine is disclosed. The engine is of the type having engine intake and exhaust valves with elongated valve stems. The actuator has a power piston reciprocable along an axis and adapted to be coupled to an engine valve and a pneumatic arrangement for moving the piston, thereby causing an engine valve to move in the direction of stem elongation between valve-open and valve-closed positions. The pneumatic arrangement includes a pair of control valves which are movable relative to the piston for selectively supplying high pressure air to the piston. Each control valve includes a thin walled portion having an inner cylindrical surface which slidingly egnaging a portion of one of the enlarged diameter cylindrical portions of the piston. The inner cylindrical surface includes an end portion of enhanced strength and reduced inner diameter which is too saml to receive the enlarged diameter cylindrical portion of the piston. The piston includes enlarged diameter cylindrical portions which cooperate with the motion of the corresponding control valve to stop the supply of high pressure air to the piston. A pneumatic damping arrangement imparts a first decelerating force to the piston when the engine valve reaches a first separation from one of said valve-open and valve-closed positions to begin reducing engine valve velocity as the engine valve approaches said one position, and imparts a second lesser decelerating force to the piston when the engine valve reaches a second lesser separation from that one position. A resilient member cooperates with and is deformed by the air control valve to prevent the application of piston moving air pressure to the piston when the air control valve is in the closed position, and included is an arrangement for adjustably selecting the amount of deformation of the resilient member when the air valve is in the closed position. An initializer to force the piston to one of its extreme positions upon start up, a pressure regulator, and an arrangement for minimizing surface tension induced valve sticking problems are also disclosed.

Abstract: For space and cost reasons, a very simple method for use in a call forwarding system is to be provided which allows speech bytes to be switched through from one channel of a PCM highway to another channel of another PCM highway, the two highways not necessarily being bit synchronous. This is achieved in that the two highways (L) are connected via interface circuits (LIF) to in each case one PCM bus (A, B). The two PCM buses are operated byte-synchronously at a transfer rate which corresponds to a bit clock frequency which is immediately above the tolerance band of the PCM highways. The input from the interface circuits to the buses and the output from the buses to the interface circuits occurs alternately and at fixed times. The interface circuits control the input and output in such a manner that no bytes are corrupted. The switching-through of the bytes between the two buses is carried out in a very simple manner by means of a dual-port RAM. <IMAGE>

By also utilizing discrete, large area switching elements (50, 52, 54, 56, 58, 60, 62, 64, 66) such as diodes or transistors, for addressing the individual picture elements operatively disposed in any given row or column of the structure, all of the active elements of the large area display are capable of manual manipulation. In this manner, the cost of even very large area displays is minimized and inoperative or defective pixels or switching elements are readily replaceable. The use of V-shaped or "butterfly" lenses (82) about the e periphery of each of the pixels covers the interstices (72, 74) of the support structure (18).

Abstract: A process for preparation of a vinyl chloride polymer comprising the steps of subjecting an aqueous medium containing vinyl chloride monomer or a mixture of vinyl chloride monomer with other vinyl monomer, a polymerization initiator and a dispersant to high-speed shear agitation at a shear rate of 10⁴ sec⁻¹ or above to prepare a suspended dispersion containing fine particles of the monomer(s) dispersed therein, then subjecting the suspended dispersion to low-speed shear agitation at a shear rate of from 10 to 100 sec⁻¹, and thereafter starting suspension polymerization. Even with a decreased amount of dispersant, the process inhibits the coarsening of the polymer particles, to yield the polymer with a narrow particle diameter distribution. Deposition of scale and formation of fish-eyes are also prevented effectively.

Abstract: According to the existing prior art, the openings of the grids of electron gun systems are produced using a stamping technique. Since the required tight tolerances for these openings 13.1, 13.2, 13.3 can be implemented only by means of precision stamping machines, it is proposed according to the invention to clad the openings 13.1, 13.2, 13.3 with deep-drawn insertion sleeves 14.1, 14.2, 14.3 and to connect them fixedly to the grid 10.

Abstract: A method for extracting information from a document bearing (a) first indicia detectable in a first scan mode, using light in a first spectral range, but not detectable in a second scan mode, using light outside the first spectral range, and (b) second indicia detectable in either the first scan mode or second scan mode, where the second indicia represent information encoded in one or more forms decodable by automated symbol recognition resources, comprise several steps. One or more areas of interest on the document are defined in which the second indicia may appear, with the definition including information specifying the form of encoding for the second indicia. The document is scanned in the second mode, using a scanner that produces a pixel image of the indicia detected and the resulting pixel data are stored in a memory device. An area of interest is selected from those defined for the document and the pixel image of that area of interest is processed with an automated symbol recognition resource suitable for the form of encoding specified for the second indicia in the selected area of interest to produce one or more output records incorporating symbol information representative of the second indicia.

Abstract: In an image sensing apparatus such as a video camera, an evaluating value for exposure control and determination of a gamma correction value is computed (12) in response to a video signal obtained by an image sensing device (3,4) for each of a plurality of sampling areas (Aa,Ab...Af) set on an image sensed picture. When an evaluating value (10a,10b...10f) exceeding an allowable range with respect to a predetermined reference value (16) is included in the evaluating values, it is determined that an abnormal luminance portion (11a,11b...11f) exists in the corresponding sampling area, so that weighting of the evaluating value is decreased, whereby the effect of such an area on exposure adjustment is restrained. The average of the sampling areas (Aa,Ab...Af) based on the weighted evaluating values is compared (17), so that an error signal is applied to the variable amplifier (5) and to the iris driving circuit (19). In addition, the picture contrast is computed from the ratio of the maximum value to the minimum value (41,44) of the evaluating values (10a,10b...10f), whereby the most suitable gamma correction value is determined (81) based on this picture contrast.

Abstract: Human aesthetic evaluation of a finished painted surface, such as an automotive body, is automatically simulated by analyzing a distorted reflected test pattern from the finished surface. Fourier power spectra of the distorted test pattern are generated to form a parameterization of the reflected distorted test pattern. A correlation is statistically made to reference Fourier power spectra, each of which has been associated with a specific human aesthetic evaluation, such as wetness, dullness, softness, brightness, and the like. The Fourier power spectra of the distorted reflected image are automatically generated through a digitized two dimensional pixel map, which are mapped into functions of the edge direction and edge intensity of the pixels. The functions are then Fourier transformed into Fourier power spectra and correlated with reference reflected patterns. Alternatively, the Fourier power spectrum of the distorted reflected pattern is optically generated by use of collimated coherent light in a Fourier transform lens. After that, the necessary parameterization is extracted from the optical Fourier transform plane and correlated to previously recorded aesthetic human evaluation. A segmentation parameter is also used for correlation with a reference segmentation indicator.
