Title: Semiconductor strain measuring device
IPC: G01L9/00
Filed: 1973-03-21
Abstract: 1362616 Stress transducers WELWYN ELECTRIC Ltd 21 March 1973 [21 March 1972] 13096/72 Heading G1N [Also in Division H1] A strain sensitive semi-conductor device Figs. 4, 5 comprises a Wheatstone bridge network of diffused Piezo resistive semi-conductor elements 15, 16, 17, 18 e.g. p-type in a chip 14 of e.g. n-type Si wherein an insulant film of e.g. Si O 2  (not shown) covers the surface and is apertured at 19 to 26 to expose the ends of the respective elements. Conductive films 27, 28 29 of e.g. Al are evaporated on to the surface to inter-connect elements 15, 16; 17, 18; 15, 18, respectively through the relevant openings, and a resistive link 30 of e. g. a single track of Al is evaporated on to inter-connect elements 16, 18. An energizing source is connected to conductors 27, 28 and a galvonometer to conductor 29, while its free connection is made to a probe slidable on link 30 to produce initial bridge balance at a point to which a permanent lead is thermocompressively or ultrasonically bonded. Subsequently the chip is applied to a structure to measure strain therein. In a modification Figs. 6, 6A (not shown) adjacent resistive tracks may be evaporated on and connected to the free ends of elements 16, 17 and the balancing probe is movable as a link connecting the tracks for initial balance, and a permanent link conductor is subsequently bonded. The tracks may terminate in connecting pads enabling the track resistances to be measured accurately, and the balance position of the bridging connector to be calculated if the tracks are uniform in width and resistivity. In a further modification Figs. 7, 8 (not shown) a Si diaphragm bearing the Piezo resistive elements is secured at its periphery and exposed to a fluid-pressure to be measured for deflection. First elements of opposite conductivity type are diffused in opposed peripheral regions and second elements in the central region; and the diaphragm is coated with insulant oxide exposing the elementary ends. Pressure distortion compresses the first elements and tensions the second elements, which are connected in a bridge by evaporated aluminium films and a resistive element, on which the galvonometer free connection is slidable for initial balance and subsequent bonding. Dual connectable adjacent tracks may replace the element.

Title: Polyimide filaments
IPC: D01F6/76
Filed: 1965-03-29
Abstract: 1,038,738. Polyimide filaments. E:I. DU PONT DE NEMOURS & CO. March 29, 1965 [March 30, 1964], No. 13200/65. Heading B5B. Polyimide filaments are made by spinning into a gaseous atmosphere a solution of a polyamide-acid of pyromellitic dianhydride and a diamine of formula wherein X is O or S to form a filament, and converting the filament to the pyromellitimide under a tension of 0À0-0À5 g./d., the filament being drawn before and/or after conversion to pyromellitimide, the total draw ratio being at least 1À4 times. The spinning solution comprises a solution of the polyamide-acid in an organic solvent, e.g. N,N-dimethylacetamide or pyridine. The solution contains e.g. 15-25% by weight solids and is desirably maintained below 80‹ C. prior to spinning. The solution is extruded into a column containing a cocurrent flow of dry gas, e.g. nitrogen at 200-280‹ C. to form polyamide filaments in which 8-16% of the amide linkages are converted to imide during their residence in the column. The as-spun filaments are then drawn and completely converted to polyimide. Drawing before conversion may be effected in air or in water at 50-90‹ C., or concurrently with washing the filaments in distilled or deionized water. Drawing after conversion may be carried out during a tempering step, which may comprise heating the filaments to at least 380‹ C. The tempered filaments may then be annealed. Conversion of polyamide to polyimide may be effected chemically, e.g. by immersing the polyamide filaments in a dehydrating agent such as an acid anhydride or a carbodiimide, or by thermal means, as by heating to at least 200‹ C. for 1 to 120 minutes, while being supported to avoid tension. The polyimide filaments have a straight tenacity of at least 3À0 g./d., a transverse tenacity of at least 1 g./d. and a flex life of at least 1000 cycles.

Title: Improvements in circular knitting machines

Filed: 1952-05-30
Abstract: 715,417. Knitting - machines. MELLOR, BROMLEY & CO., Ltd. May 30, 1952, No. 13800/52. Class 74 (2) A cylinder-and-dial machine has a transfer instrument associated with each needle of both sets so as to enable all the loops on the dial needles to be transferred to the cylinder needles and, after a selection of the' cylinder needles has been made, the loops on the selected cylinder needles to be transferred to associated dial needles. Subsequent to this latter loop transference, the latches of all the dial needles are closed to ensure that only the dial needles with loops knit at the next knitting location and a further selection of the cylinder needles last selected knit at the knitting location. The invention is described in connection with a four feeder machine having eight pattern drums operating selector bits controlling cylinder needle jacks. At a position G, the cylinder needles are raised sufficiently by cams 22 to take loops from the dial needles which are projected to a transfer position by transfer cam 59, the cylinder needles being previously raised to open their latches by cam 90 in preparation for receiving the dial needle loops. After having received the dial needle loops, a selection of the cylinder needles is made by the pattern drum at position D. The dial needles are prepared to receive the loops from the seleected needles by being advanced by cam 71 and retracted by cam 72 so as to cause a latch opener to open all of the latches. The dial needles are then sufficiently projected to receive the loops of the selected cylinder needles by cam 65, the cylinder needles being raised to transfer height by transfer cam 45 acting on the jacks. The latches of all the dial needles are immediately closed by plate 73 as the dial needles are retracted by cam 66. A further selection of the cylinder needles is then made after which the latches of all cylinder needles are opened by a latch opener preparatory to receiving yarn and knitting at the location under the influence of stitch cam 17. The dial needles also are advanced by clearing cam 60 or 61 so that only the dial needles with loops on have their latches opened to receive yarn, and are caused to knit by stitch cam 62. In certain instances, selecting drums may be provided at the locations D only, a selecting cam 91a being provided to co-operate with reversing cam 92 so that the jacks which were previously selected are inoperative and those that were inoperative now become operative. Specification 574,226 is referred to.
