Filed: 1956-07-05
Abstract: A dried feedstuff of which the components do not regrade in course of transportation or storage is made by treating the feed components with water in an amount not less than 50% of the mixture of components and water for sufficient time to ensure that the water soluble portion dissolves to a substantial extent, and the wet mixture is dried.  The feed components may include liquid fat, molasses or fish solubles.  According to an example, to a mixture of 300 lbs maize meal, 200 lbs each of barley meal and wheat meal, 50 lbs each of fish solubles and ground-nut meal, 100 lbs molasses, and 10 lbs each of salt, limestone flour and bone meal, there was added 1250 lbs water.  Mixing was continued for an hour, during which the temperature was raised to 90-100 DEG F. by admission of steam.  The heated mixture was then cooked at 212 DEG F. for thirty minutes and the cooked porridge-like product obtained was dried on a rotary drier into thin sheets of 12% moisture content which on cooling were broken into flakes. Heat-susceptible vitamin-rich oil and antibiotics were applied to the cooled sheets prior to the breaking into flakes.ALSO:A dried foodstuff of which the components do not regrade in course of transportation or storage is made by treating the components of the food with water in an amount not less than 50% of the mixture of components and water for sufficient time to ensure that the water-soluble portion dissolves to a substantial extent, and the wet mixture is dried.

Title: Memeory circuit arrangement utilizing one-transistor-per-bit memory cells
IPC: G11C11/4097
Filed: 1977-05-20
Abstract: 1524665 FET memory cell NIPPON ELECTRIC CO Ltd 20 May 1977 [21 May 1976] 21348/77 Heading G4C A memory cell, Fig. 1, has first and second cells 1, 4 connected as shown between lines 2, 5 and digit lines 3, 7, a differential sense amplifier 11 serving both cells, and means to supply complementary signals to the IN/OUT lines 81, 82. READ OPERATION: Digit lines 3, 7 are precharged to V 1  via 31, 32. When cell 1 is to be read, 8 is enabled and AX set to V 1  (logic 1), and #AX to logic 0. Thus only 23 is enabled and the information in cell 1 transferred to line 3, line 7 remaining at V 1 . Sense amplifier 11 is enabled and the amplified output signal is available as "TRUE" and "COMPLEMENT" outputs at 81, 82 respectively when 71, 72 are enabled. The second cell 4 is selected by inverting AX, #AX, when the "TRUE" and "COMPLEMENT" "outputs appear on 82, 81 respectively. WRITE OPERATION: To unite cell 1, AX is set to V 1  (logic 1) AX to logic 0, 12 enables 71, 72 and "TRUE" and "COMPLEMENT" outputs applied to 81, 82 respectively. To write into 4, AX, #AX are interchanged, and "TRUE" and "COMPLEMENT" signals applied to 82, 81 respectively. Complementary input/output signals are said to enable faster switching times to be achieved. The circuit may be used in a matrix any (Fig. 2, not shown), in which separate IN/OUT lines may be used (Fig. 3, not shown). In a driver circuit, Fig. 4, complementary signals are generated from a single-ended input using two push-pull output stages Q7, Q8 and Q9, Q10 driven by invertor stages enabled by WRITE COMMAND signal WE which gates the load MOSTS Q2, Q5 via MOSTS Q1, Q4, boosting capacitors C10, C11 being incorporated. In Fig. 5 reference cells 22 incorporating suitably dimensioned capacitors C2 allow the logic 1 level stored in the memory cells to be less than the precharge voltage V 1 . During the READ operation, the precharge signal P discharges C2 the selected cell, so that for example when cell 1 is connected to line 3, by enabling line 60, a reference cell 22 is connected to the other line 7, whose voltage, previously V 1  is reduced by charge flow into its respective capacitor 22. A further embodiment (Fig. 6, not shown) has separate NOR gates (8<SP>1</SP>) controlling each line 2, 5.
