Abstract: ABSTRACT OF THE DISCLOSURE   Disclosed here is a matrix operation device utilizing a charge-coupled device (CCD)   This device performs matrix multiplication for an input electrical signal by making use of a CCD.  The operation is carried out by utilizing a plurality of systems of the split electrode type convolution operation unit using a CCD.  More specifically, the multiplication is carried out by means of a split electrode CCD.  A signal to be processed is sampled by a resistor in the input side or by a delay circuit.  The sampled signal enters the operation circuit in the form of a time series (sequence) consis-ting of the samples of said signal, and in the respective coefficient is multiplied to each sample.  The method of splitting the electrode corresponds to each coefficient in the matrix.  The samples multiplied by the coefficient are added in the output side and converted into the output signal, namely, a signal corresponding to the development of the matrix multiplication.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus for measuring the refractive proper-ties of a sphero-cylindrical lens system of the type utilizing an incident light beam scanned in at a predetermined radius about the central axis of the lens system to provide a refracted beam. A generally opaque mask having an annular transparent portion is positioned in the path of the refracted beam, to eliminate errors caused by deviations in radial height from the scanning radius of the refracted beam as it exits the-lens system due to refraction within the interior of the optical system. A position-sensitive photodetector generates a signal indicative of the instantaneous position in a given plane due to refraction of the portions of the light beam passing through the mask. The photodetector output signal is then processed to provide an indication of the refractive properties. Various embodiments of the mask are also disclosed. Also permutations of the above including pinhole aperture, input light and other detection means is discussed.

Abstract: CHECK VALVE ASSEMBLY          Abstract of the Disclosure A check valve assembly adapted for connection to a high pressure reciprocating pump cylinder, comprising valve body means, inlet check valve means and outlet check valve means.  The valve body means has an inlet end adapted for connection to the pump cylinder and an outlet end adapted for connection to a high pressure outlet line.  The inlet end has a planar surface adapted to be exposed to the interior of the pump cylinder.  The valve body means also includes a low pres-sure inlet passage opening in the planar surface for providing communication with a source of low pressure fluid and a high pressure outlet passage extending between the planar surface and the outlet end.  Such passages are parallel to one another and spaced apart a distance at least as great as the radius of the high pressure outlet passage.  The inlet check valve means is mounted entirely on the exposed planar surface in association with the inlet passage and prevents high pressure fluid backflow into the inlet passage.
