Abstract: APPARATUS AND METHOD FOR HANDLING SOLIDS IN LIQUID          ABSTRACT OF THE DISCLOSURE                     Apparatus has a receiving chamber subjected to low pressure to receive solid/liquid mixture through inlet valve thereof. The chamber also has outlet valve to discharge the mixture, an admitting valve to raise pressure in the chamber, and quantity sensing structure responsive to predetermined quantity of mixture within the chamber. The inlet valve is positioned above a predetermined upper level of mixture within the chamber, and a riser constrains the mixture to move initially upwardly and then, optionally, downwardly prior to discharging through the inlet valve. The riser is shaped to cause solids that might otherwise tend to rest initially adjacent the inlet valve, when the mixture flow therethrough ceases, to fall under gravity either forwardly through the inlet valve, or backwardly towards mixture within the delivery duct. Time delay structure delays the opening of the admitting valve to raise pressure in the chamber sometime after attaining the predetermined quantity of the mixture, which also delays closing the inlet valve which provides time for solids to clear the inlet valve before closure thereof. The time delay structure uses either a reservoir for a single chamber embodiment, or for a twin chamber embodiment, the remaining chamber serves also as a reservoir. Use of a reservoir or chamber increases the time required for sufficient low pressure to be attained to actuate the admitting valve. Use of twin chambers provides means to receive mixture essentially continuously.

Abstract: Abstract of the Disclosure A solid state storage memory system is disclosed.  The storage section of the device is divided into two groups, with each group including at least one, and as many as four storage sections.  A port is provided for delivering words to and receiving words from the memory.  A data path between the port and the memory is two words wide, with one word received from or delivered to each group.  Each section includes a register, with the registers of different sections in the same group being connected in a series fashion to provide a one word data path between the storage sections. Words stored or retrieved from a section are passed through its respective register.  In a write operation, words to be stored are transmitted serially from register to register and captured by all sections simultaneously on the same clock cycle. Addressing means within each section then routes the word to the appropriate memory circuit within the sec-tion.  In a read operation each section loads its register simultaneously, after which the data words are transmitted in a serial fashion from register to register out of the memory to the port.  The memory circuits within each section are organized into a plurality of banks, each of which may be addressed independently of one another, so that a section may capture at least one word per clock cycle.  A further circuit is provided to reverse the order of words received from the port during a write operation to cause the words to be in proper order when read from the memory.

Abstract: ABSTRACT OF THE DISCLOSURE:     In order to interpolate each instantaneous picture skipped between a preceding and a succeeding picture in a moving picture signal comprising a movement vector signal, a decoder comprises a movement region detector responsive to the moving picture signal for detecting a movement region for a moving or movable body in each of the preceding and the succeeding pictures, a vector selector for selecting a representative movement vector for each movement region from individual movement vectors reproduced from the movement vector signal, and an interpolator responsive to the movement region and the representative movement vector for interpolating the skipped picture between the preceding and the succeeding pictures.  Preferably, the decoder is a predictive decoder for a moving picture signal of the above-mentioned type and including a prediction error signal for the movement vector signal.  The vector selector selects the representative movement vector in consideration of that significance of each reproduced movement vector which is evaluated by the prediction errors represented by the prediction error signal.  In either event, the representative movement vector may be the individual movement vector which is most frequent in each movement region.  Alternatively, the representa-tive movement vector may be an average of the individual movement vectors in each movement region.

Abstract: RESINOUS-LIKE EMBOSSING MEMBER FOR USE IN EMBOSSING PRESS, FOR GREETING CARDS, AND             METHOD OF MAKING SAME                 ABSTRACT OF THE DISCLOSURE A method of forming a resinous-like embossing plate and the resultant relatively low cost resinous-like embossing plate product, adapted for use in an embossing and diecutting press for embossing a selected design onto paper greeting cards.          The method comprising providing a line sketch of a selected design, making a photographic negative of such line sketch to capture all of the detail thereof, and using the negative to apply the line sketch design to both sides of a relatively thin sheet of relatively soft embossable material.  Manual indenting or embossing of the design into the embossable sheet from a side thereof is accomplished, utilizing for instance a wooden or plastic skewer to provide a female matrix on one side of the embossable sheet.  The embossable sheet may then be reversed so that the male or convex portion of the matrix design faces upwardly and such male matrix is disposed in a mold enclosure, after which liquid plastic is poured into the mold enclosure and utilized in conjunction with fibrous reinforcing material such as fibrous mats, to form, upon setting of the liquid plastic, a relatively low cost embossing plate for use in a press, in embossing the selected design onto paper greeting card stock.  A generally conventional plastic counter is utilized in the press in conjunction with the produced embossing plate, for accomplishing the embossing of the design onto the paper greeting card stock.  For non-intricate or little detail designs, the use of the photographic negative step can be eliminated, and the design may be traced directly onto the embossable metal plate for subsequent tooling.
