Abstract: 732,447. Testing physical qualities of materials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 13, 1953 [May 16, 1952], No. 12452/52. Class 106 (2). An apparatus for testing lubricants comprises mating surfaces in the form of cylinders set with their axes crossing, and means for moving the cylinders so that any one point on either cylinder only comes in contact once with one point on the other, provision being made to press the cylinders together under a known force. One cylinder 11 may be rotated in a milling machine. To the table 13 of the machine is fulcrumed a lever 14 extending over the rotating cylinder 11, the outer end of the lever 14 carrying a pan 15 for a load. Near its fulcrum, the lever 14 carries a non-rotating cylinder 16 with its axis set at right angles to that of cylinder 11. The non-rotating cylinder 16 rests on the rotating cylinder 11 and movement of cylinder 16 is effected by automatic longitudinal and cross feeds of the table. The fulcrum of the lever 14 may be formed by crossed steel strips 17, 18 secured to spaced brackets 19 on a base-plate 20 bolted to the machine table 13. The frictional forces between the cylinders 11, 16 tend to move the lever 14 longitudinally and this force can be measured by electric strain gauges attached to the crossed strips 17, 18. The non-rotating cylinder 16 is mounted within an opening in a steel block 21 and by rotating this cylinder a little between tests, this cylinder can be used for a series of tests. As shown, the load between the two cylinders 11 and 16 varies on operation of the longitudinal and cross-feed mechanisms. If the lever 14 and its hinge are arranged at right-angles to the position shown, the load between the cylinders 11 and 16 remains constant ; the cylinder 16 being, adapted to remain at right angles to the cylinder 11.

Filed: 1973-03-16
Abstract: 1423909 Memory cells RCA CORPORATION 16 March 1973 [24 March 1972] 12752/73 Heading H3T An arrangement, e.g. an array of memory cells, comprises a memory cell M 11  having a first point Q coupled via the conduction path of at least one transistor X 11 b, Q 1 b to a first conductor 1, a second point #Q coupled via the conduction path of at least one transistor X 11 a, Q 1 a to a second conductor 2 and a clamping arrangement R 1 , R 2  wherein, when in operation the logical levels at Q, #Q are such that the transistors X 11 b, Q 1 b operate in a common source mode and transistors X 11 a, Q 1 a operate in a source follower mode and the conductor 1 is clamped to the potential level at Q, the clamp R 1 , R 2  responsive to the potential on conductor 1 clamps the conductor 2 to a reference potential. In operation, write in is achieved by enabling FET 201 and the selected one of the FETs 202b, 202a depending on whether a "1" or a "0" is to be written in as well as enabling the relevant addressing FETs X 11 a, X 11 b, Q 1 a, Q 1 b for the selected cell. For read-out, the same addressing transistors are enabled. With a logical level of "0" at #Q, FETs Q 1 a, X 11 a operate in a source follower mode and their gate source thresholds must be exceeded before they are rendered conductive i.e. the sense line 2 is not clamped to the low potential at #Q but has a high voltage level which may exceed the threshold voltage of I 1  in the sense amplifier S 2  to turn it on erroneously while the sense amplifier S 1  is turned on by the correct "1" level at Q. However the clamp R 1 , R 2  detects the presence of a high level at one of the sense lines to clamp the other to earth potential. Further FETs D 1 A, D 1 B, D 2 A, D 2 B, D 1 S, D 2 S may be used in addition to set the digit lines and sense lines to zero potential before a read or write-in. Fig. 2 (not shown) is a simplified version of the arrangement including a single memory cell.

Abstract: 276,718. Tudor, J. May 21, 1926. Electrodes. - In order to economize space more particularly in quick-discharge accumulators of the " starting battery " type, plates of similar polarity are grouped in units arranged in alternative relation with respect to similar units of opposite polarity, so that the number of separators necessary for separating plates of opposite polarity is reduced. Fig. 1 shows one such arrangement in which two groups each made up of two positive plates are separated by a group of two negative plates and contained between two outer single negative plates, the number of separators E being thus reduced from eight to four as compared with the usual arrangement, and the number of negative plates from five to four. In other arrangements a group of four positive plates is spaced between two groups of two negative plates, the number of separators being reduced to two, and in a third arrangement groups of four positive and four negative plates separated by a single separator are employed. In order to provide a free flow for the electrolyte, a number of holes o, Fig. 4, may be formed in the grid of the electrode, or small holes may be pierced in the active mass. Fig. 10 shows a section in plan of another form of electrode in which a central plate A coated with oxides is bounded on each side by plates B formed by vertical ribs n which prevent disintegration of the active material and at the same time provide large plate area while giving free flow to the electrolyte through the spaces e. Compound plates may be built up of alternate plates such as A and B, holes being provided in the plates A to allow the electrolyte to reach the interior of the plate.
