Title: Method and means for load testing openended piles penetrating  the soil
IPC: G01N33/24
Filed: 1972-12-20
Abstract: 1413160 Testing building piles SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 20 Dec 1972 58761/72 Heading G1S An open-ended pile 1, Fig. 1, having been driven into ground 2 which may be underwater, is tested to determine its load carrying capacities by first removing the soil plug formed in the lower end, then placing a bearing plate 3 at the bottom of the pile with a hydraulic jack 5 on top, positioning a cable supported plate 6 on top of the jack so that clamps 8 may be extended to grip the inside wall of the pile, and extending a weight and pulley carrying frame 15 over the pile so that cables 10, 11, and 12 are attached as shown. In operation the jack is extended to move the bearing plate 3 or the pile 1 or both, the movements being ascertained and measured by watching the weights 13, 18. The jack forces required to produce various relative movements are noted and used  to determine the resistance to the pile at that particular depth. Fig. 2 shows an arrangement where a length or lengths of inner tube 24 are positioned between a bearing plate 23 and an upper plate 25 holding jacks 26 against abutments 28 welded to the pile 20, and in Fig. 3 (not shown) the housing of a jack is fixed to the pile whilst its piston is fixed to an inner tube extending down to a bearing plate.

Title: High Performance Dynamic MOS Read/Write Memory
IPC: H03K3/356
Filed: 1979-09-06
Abstract: A random access read/write MOS memory device consisting of an array of rows and columns of one-transistor memory cells employs a bistable sense amplifier circuit at the centre of the dynamic type in that coupling transistors connect the column line halves to the cross-coupled driver transistors. Active load devices connected to the column line halves provide pull-up of the voltage on the one-going column line half to a full Vdd level. An improved circuit is used for the address inputs, data inputs, or the like, to permit undershoot of the voltage on input lines, while not requiring substrate bias on the semiconductor chip. Buffers function to latch the data or address to allow the inputs to change states. The buffer is activated by TTL level inputs, exhibits low capacitance at its input, and switches states fast enough to allow rapid multiplexing of the addresses. Noise immunity is improved by selective implants of some of the transistors. A heavily doped guard ring, N+ for a P-type substrate, connected to Vdd, surrounds the transistors in the input stages to avoid the effects of injection of minority carriers by forward biasing of PN junction regions at the input. <IMAGE>
