Title: Monolithic memory system
IPC: G11C11/414
Filed: 1971-08-18
Abstract: 1334307 Transistor memory matrix INTERNATIONAL BUSINESS MACHINES CORP 18 Aug 1971 [22 Sept 1970] 38661/71 Heading G4C An integrated circuit data store includes a matrix of semi-conductor chips each comprising an array of memory cells together with associated addressing circuitry, a means for maintaining the chips in a low power state for retaining stored data, matrix row and column select circuits for applying row and column signals for selecting a particular chip, and gating means forming a part of the chip addressing circuits and being responsive to the row and column select signals and memory cell row address data to apply higher power to a selected row in the selected chip for read/write operations. As described each chip includes 16 rows of cells and a memory cell row decoder 37 comprising four true-complement generators 201 (of which two only are shown) one for each input W0-W3. The chips themselves are selected by row Y and column X signals applied to inputs 25, 27 and 21. When the chip is inactive, i.e. no X pulses applied to inupt 21, the row decoder circuits generate outputs W0, W0, W1 . . . W3 all of which are logical 1. When an X pulse is applied each true-complement circuit generates outputs W = 1, #W = 0 if the corresponding input is 1 and W = 0, #W = 1 otherwise. The outputs W are connected to a circuit 24 which couples various combinations of the signals to each of 16 row gates in the row address circuits 38. Each of these gates, e.g. T101, applies a high level voltage to its associated row if all its four inputs are at 1 and a gating signal is present at input 28. The gating signal appearing due to the presence of the X and Y chip select signals applied at inputs 25, 27. In operation the row address signals are applied to selector circuits 37 when the memory is in a low power state and the decoder outputs W0, #W0 ... #W3 are thus all 1. When the chip select signals X and Y appear the decoder outputs change, all non-selected row gates having at least one input brought down to 0, and the selected row gate still receiving four 1 inputs. In this way the delay normally required for the selected decoder output combination to switch to all 1's is eliminated since all the outputs are in this state when the chip select signals are applied. Thememory cells 39 described are conventional (see U.S.A. Specifications 3,423,737, 3,505,573) and are based on cross-coupled double emitter transistors, writing into and reading from the cells being by way of bit lines 43, 44. In order to prevent data stored in the cells from being lost when they are switched into the higher power state a circuit 36 is provided to act as a delay and ensure that word line 30 is raised to the higher voltage level before line 31 and remain in that state until line 31 has reverted to the lower voltage level.

Abstract: 1,120,185. Cooling I.C. engines &c. COMPAGNIE FRANCAIS THOMSON HOUSTONHOTCHKISS BRANDT. 2 Sept., 1966 [7 Sept., 1965], No. 39312/66. Heading F4U. [Also in Division F1] A moving component of a machine such as an I.C. engine or a compressor is cooled by the provision therein of a sealed chamber containing an evaporable liquid, a further chamber having connections to an external circuit for the circulation of a secondary coolant, and a heatconductive wall between the chambers against which the liquid phase of the evaporable coolant is thrown by virtue of the movement of the component in operation of the machine. As shown, the component to be cooled is the lobed rotor 5 of a rotary piston I.C. engine, the interior of the rotor being divided by a corrugated partition 24 into chambers 38 and 40, the latter of which is sealed and partly filled with a primary coolant such as water, ethyl alcohol, trichloroethylene or tetrachloroethylene. Chamber 38 is filled with oil and is connected to an external circuit including an oil cooler 88 and pump 86, via bores and passages 32-35 formed in the engine shaft 3; the oil also serves to lubricate the shaft and other bearings. In operation the rotor has a radial reciprocating component of motion which causes the liquid phase of the primary coolant to be thrown alternately against wall 24 and the internally ribbed outer wall 6 of the rotor, so cooling wall 6 and transferring its heat to the oil in chamber 38. Formulµ for determining the configuration of ribs 39 are given. The stator of the engine, which is shaped to define combustion chambers 10, has a peripheral chamber 12 which is also filled with a vaporizable coolant, ribs 13 being formed on the outer surfaces of each of the combustion chambers. In a further embodiment (Fig. 6, not shown) the primary coolant in the interior of a hollow reciprocating piston transfers its heat to lubricant circulating in a helically wound tube immersed in the primary coolant.

Abstract: 1,223,073. Slush moulding. DAVIDSON RUBBER CO. Inc. 11 Aug., 1969 [29 Aug., 1968], No. 40000/69. Heading B5A. In a slush moulding process in which a twolayered article is produced, the mould is heated by the impingement of streams of hot gas and is oscillated about a fixed pivot during formation of both the first and second layers. The use of such a heating means together with the movement of the mould ensures a reasonably even wall thickness since the number of bubbles and the amounts of material retained within any intricate parts of the mould are reduced. In the particular embodiment, moulds 12 are mounted upon a chain conveyer 10 and passed through a station I in which a preheated mould is filled with liquid material ; a station II in which the mould is inverted to remove excess material, oscillated about an axis 30, and heated by an oven 32 to gel the deposited layer; a station III at which further material is added to the mould, the heat retained by the mould causing a second layer to be formed upon the first; a station IV at which the mould is inverted, rotated, and heated by an oven 62 similar to oven 32 to fuse the layers; a station V at which cooling is effected; and a final station VI at which the moulded article is removed from the mould. The ovens each comprise a gas burner B, a compressed-air tube 47, and a perforated baffle member 38 through which the heated combustion products are propelled on to the mould by the air from tube 47.

Abstract: In a method of quenching a continuous web of material to a desired temperature level, the material is contacted as it enters the quenching bath with a stream of quench medium at a controlled temperature, or where the web has been differentially coated, e.g. in the case of tinplate, separate streams of coolant at differing temperatures may be brought into contact with the two sides of the web.  Temperature sensing means are provided close to the point where the coolant meets the web, whereby the temperature or volume of the coolant is controlled to maintain the desired quenching temperature.
